Solar Generator


Solar Power versus Generator - the Choice


The cost of sun based power versus generator is considerably less finished the long haul.

The underlying expense of a sun oriented power framework will be more prominent than that of a generator framework. This is regularly the reason individuals introduce a generator as opposed to pick sunlight based power. One must look past the underlying expense, be that as it may, to get the full correlation of sun oriented power versus generator.
* Solar power, once introduced, has little upkeep or further cost. There is no fuel to buy, since the sun's vitality energizes the framework.

* Generators are not really. After establishment, a generator will require consistent overhauling by an expert like clockwork. Generators require fuel - a cost that is continually expanding. Moving generator parts must be supplanted now and again because of wear and tear.

Sun powered Power versus Generator - Convenience

Accommodation is another factor to consider when taking a gander at sunlight based power versus generator control. Sun oriented power is considerably more helpful than generator control.

* Solar power might be less advantageous to buy and introduce, since it isn't as generally accessible as generators. This is because of the as of now little market for sunlight based power. As the market increments, notwithstanding, this will be to a lesser degree an issue. Sun oriented power frameworks have no moving parts to destroy or require oil. Once introduced, sun powered power requires little consideration. The client can nearly overlook it.
* Generators are broadly accessible, so advantageous to buy and introduce. A generator must be observed every now and again to make certain adequate fuel is accessible. It must be refilled frequently when utilized as a standard wellspring of intensity. Fuel must be requested and conveyance taken - or fuel must be pulled by the proprietor. The framework must be adjusted two times per year. This overhauling will incorporate channel changes, an oil change, a tune up, and finish review of the whole unit. Worn parts must be supplanted.

Sun based Power versus Generator - Efficiency

The sun based power versus generator fight incorporates the matter of effectiveness, as well. Which is more savvy? The realities appear to point to sun oriented power.

* Solar power is gotten in through the boards, free of cost, and put away in batteries. It is prepared for utilize when required, yet in the midst of decreased use, the power stays away.

* Generators run continually, paying little heed to the measure of intensity being utilized at a given time. As they run, they devour exorbitant fuel. At the point when control use is decreased in brilliant sunlight, generators must keep on running.

Sun based Power versus Generator - Dependability

Some contend that, in contrasting sun oriented power versus generator, we should analyze the trustworthiness factor. Around there, they assert, generators win.

* Solar power is extremely tried and true in areas that have brilliant daylight 300+ long periods of the year. In zones with less daylight, or amid times of darkness and tempest, sun oriented power is less reliable. The framework will keep on providing power from charged batteries, yet will in the long run go dead. Having said that, it must be noticed that Germany, which has far less radiant days than a large portion of North America, is said to have significantly higher use of sunlight based power. The issue of trustworthiness appears not that huge.

* Generator frameworks don't rely upon daylight. They do, in any case, rely upon fuel. In the event that tempests or some other calamity upsets one from renewing the fuel supply, generators additionally end up pointless.

Sun based Power versus Generator - Eco-agreeableness

At long last, eco-agreeableness must be considered in any talk of sun based power versus generator. That is, which is kinder to nature: sun powered power or generator? The undeniable answer again is sunlight based power.

* Solar power has no outflows when working. There is no contamination associated with fuel creation - no ozone harming substances. It is thoroughly perfect. Sunlight based power utilizes a sustainable power source.

* A major downside to generator utilize is as yet the matter of outflows and nature. Generators are generally kept running on diesel fuel, and diesel fuel is delivered from a petroleum derivative. There are emanations in the creation of the fuel, and furthermore in its utilization. Diesel generators are a noteworthy wellspring of air contamination and high sulfur levels in North America. Presentation to diesel generator fumes can prompt wellbeing perils.

Sunlight based Power versus Generator - the Solution

For a great many people, the goals of the sunlight based power versus generator banter is to introduce a half breed framework. Utilizing sun powered influence as the principle vitality source will set aside some cash. The fuel is free. Sun powered power is helpful, proficient, and eco-accommodating. What it needs in steadfastness can be made up by having a little back-up generator for delayed shady periods.So solar generator is most important 

Generator Maintenance


 Maintenance The Power generator Proceeding & Proceeding & Proceeding.



Preventive Maintenance will be support the proprietor can perform on your RV before an issue exists. These checks are intended to forestall or distinguish potential issues that could prompt mechanical breakdown, glitch or disappointment of a part or framework on your RV. Preventive Maintenance comprises of cleaning, assessing, greasing up, altering and adjusting your RV.
Regardless of whether it's a versatile generator you use at home or the generator in your RV here are some basic PM checks you can perform to keep it in top working condition. Notwithstanding these checks you ought to dependably take after the upkeep timetable and rules that accompanied your particular generator set.

Note: These PM checks are for a gas energized generator. Diesel RVs come furnished with a diesel or propane energized generator. Counsel your generator proprietor's manual for support checks and administrations for your particular generator.

Continuously check the oil level before beginning the generator. Beginning and running a generator that is low on oil can result in expensive harm to the generator's motor. Include legitimate kind of oil as required.

Continuously check the fumes framework before beginning the generator. A harmed fumes framework can result in carbon monoxide gas getting inside the RV. Investigate the whole generator debilitate framework. Never work a generator with a harmed debilitate framework!

Keep the generator set and the compartment it is housed in clean. You can utilize packed air to help with wiping out the generator compartment and a perfect shop cloth to clean the generator set. While you are cleaning the generator check every electrical connector for secure associations.

Note: dependably wear security glasses when utilizing packed air.

Check the greater part of the channels on the generator. A regular generator may have an air channel, fuel channel and oil channel. Check your generator proprietor manual for the sorts of channels your generator has and where they are found.

Upkeep checks and administrations for a generator depend on long periods of activity. Screen the hour meter on your generator set for all support interims.
Replace the oil and oil channel (if prepared). This is maybe the most critical PM Service you can make on your generator to guarantee long stretches of solid administration. Replace the oil and supplant the oil channel at the suggested interims. In the event that you don't feel good replacing the oil and channel have an approved RV benefit focus do it for you.

Exercise the generator. There are a few reasons why you should begin and exercise the generator set all the time. Dampness develop can make harm your generator. When you practice your generator it warms up the generator windings and takes out this dampness develop. This month to month practice administration likewise greases up the greater part of the motor seals and segments and forestalls carbon develop. When you practice the generator it ought to have a heap on it and it should keep running for no less than two hours consistently. Check your generator proprietor's manual for stack evaluations particular to your unit.

Add a fuel stabilizer to the RVs gas tank or generator gas tank and run the generator sufficiently long for the stabilizer to traverse the fuel framework. This will help counteract gas related issues on generators, as not beginning or flooding. Fuel stabilizers can secure the fuel framework for up to a half year or more, yet remember the significance of practicing the generator as well.

Take after these straightforward advances, and the upkeep and administration directions in the generator proprietor's manual, and you can get long periods of solid, inconvenience free administration from your generator set.

LED Lights Save money

Tips For Saving Money on Your Power Bills by Switching to LED Lights


It's true that one of the biggest costs in running a household or commercial building is the cost of electricity needed to power lighting....until now.

Most buildings contain a combination of halogen (down lights and outdoor floodlights), incandescent (such as common light bulbs), fluorescent tubes, Sodium Va pour (such as outdoor floodlights and warehouse Hi bay lights) plus various other types of lighting.
LED Light

These can all be replaced now with LED lighting technology, and the savings in energy usage can be up to 90%...but how?

LED (which stands for light emitting diode) is a new form of lighting that offers immense benefits to the user and the environment. Replacement bulbs of all types are now available and generally fit right back into the same socket as they were removed from.

Unlike conventional forms of lighting, LED doesn't burn a filament inside the bulb for its brightness. This burning causes heat and a majority of the energy used to power traditional lights is wasted by this heat generation.

Does the latest generation of energy-saving light bulbs really save energy?
 LED Light

A major study conducted by Os ram, the giant German lighting company, provides evidence that they do. Until the release of the report Dec 2009 the answer remained unclear because no one knew if the production of LED lamps required more energy than needed for standard incandescent bulbs. If more energy were used in the manufacturing and distribution process, then the lighting industry would be harming not helping CO2 production.

To calculate what is known as a Life Cycle Assessment of LED lamps, Os ram compared nearly every aspect of the manufacturing process, including the energy used in manufacturing the lamps in Asia and Europe, then packaging them, and transporting them to Germany for sale.

Now back to saving money...

One of the easiest things to do is get yourself into the habit of turning off appliances and lights that aren't in use. This seems obvious, but do a simple experiment of your house one night. Are the kids leaving the lights on even when they aren't in the room? Is someone taking off to go to the shops or play outside while the TV continues playing in the living room?

While you're checking out light usage, look at the wattage of the bulbs you use in the lamps and overhead lights. You can probably go down a few watts: say, from 75 to 60 without noticing it too dramatically.

But switch to LED and suddenly you can go from a 50-watt halogen bulb to a 5 or 7-watt model with very similar light output.

There is very little heat generated by LED too... (typically halogen bulbs can reach temperatures up to 320 C and have been known to cause countless fires).

This means after the switch to LED you can run AIR CONDITIONING at lower speed and higher temperatures saving even more money and CO2 gases.

If you have Halogen lights chances are you have around 50 installed in the average sized 3-bedroom house. If these run daily for around 5 hours they will cost you around $820.00 per year to run (based on a conservative rate of  0.18c  per kw). If you switched these same lights to LED they would cost you around $88 per year to run- but the real benefit is the savings over their lifetime. Typically LED runs for 50 000 hrs- that's about 12 years of savings before replacement - or about $5850 in this example.

You can save a considerable amount of electricity by unplugging unused electronics. Many products still draw power even when they are not turned on. These items can contribute up to 25% of your electric bill! To save even more money - turn off the lights when you leave a room.

You can also use floor lamps instead of the overhead lights when you're working in one area (reading in bed, for example, or watching television). Its called task lighting and instead of lighting a whole room, concentrate on the tasks that require lighting. Under cabinet lighting in the kitchen or a bench light in the workshop are examples. Task lighting eliminates shadows and eases strain on your eyes.

Lets not forget the humble dimmer. Dimmers provide an additional way to save energy and money by allowing you to control the strength of the light. With most LED lights, electronic type dimmers need to be used instead of conventional incandescent types. Dimmers create a mood in a room.The dimmer the light, the less energy used, and the greater the savings.

DO they make all types of LED replacement lights now - even Fluro tubes?...The answer is YES! 
New developments in LED technology have made the humble FLUORESCENT tube outdated. While the flour tube is relatively efficient by itself, compared to LED tubes, it is a waste of energy and a major contributor to green house gases.


LED Lighting Technology

Advantages and Application Area of LED Lighting Technology



A number of the program locations which can be known and also enhance simply by LED are usually:

Transformer Protection


Transformer Protection

Transformers of differed sizes and setups are at the core of all power frameworks. As a basic and a costly segment of the power frameworks, transformers assume a critical part in control conveyance and the honesty of the power framework organize all in all. Transformers, in any case, have working points of confinement past which the transformer death toll can happen. In the event that subjected to unfriendly conditions there can be an overwhelming harm to the framework and framework gear, other than insufferable intrusion of administration to the clients. Since the lead time for repair and substitution of transformers is typically long, restricting the harm to blamed transformers is the premier goal of transformer assurance.

Transformer Protection 

Monetary effect of a transformer disappointment
• The direct monetary effect of repairing or supplanting the transformer.
• The circuitous monetary effect because of creation misfortune.
Working conditions like transformer over-burden, through flaws, and so on frequently result in transformer disappointment, featuring a requirement for transformer security capacities, for example, finished excitation insurance and temperature-based assurance. Broadened working of the transformer under anomalous condition, for example, blames or over-burdens can trade off the life of the transformer. Sufficient assurance ought to be accommodated snappier detachment of the transformer under such conditions. The kind of security utilized ought to decrease the disengagement time for flaws inside the transformer and limit the danger of disastrous breakdown to rearrange inevitable repair.
Surge arrester

Transformer Failure
The danger of a transformer disappointment is two-dimensional: the recurrence of disappointment, and the seriousness of disappointment. Frequently transformer disappointments are a consequence of "protection disappointment". This classification incorporates lacking or flawed establishment, protection weakening, and short-circuits, rather than outside floods, for example, lightning and line issues.
Disappointments in transformers can be arranged into
• Winding disappointments coming about because of shortcircuits (turn-turn issues, stage issues, stage ground, open winding)
• Core shortcomings (center protection disappointment, shorted covers)
• Terminal disappointments (open leads, free associations, shortcircuits)

• On-stack tap changer disappointments (mechanical, electrical, hamper)
• Abnormal working conditions (over fluxing, over-burdening, overvoltage)
• External flaws
Different reasons for transformer disappointment may incorporate
Over-burdening - Transformers that experience a supported stacking that surpasses the nameplate limit frequently confront disappointment because of over-burdening.
Line Surge - Failure caused by exchanging floods, voltage spikes, line flaws/flashovers, and other T&D variations from the norm proposes that more consideration ought to be given to flood assurance, or the sufficiency of curl bracing and short out quality.
Free Connections - Loose associations, inappropriate mating of disparate metals, ill-advised torquing of blasted associations and so on can likewise prompt disappointments in transformers.
Oil Contamination - Oil defilement bringing about sludging, carbon following and mugginess in the oil can frequently result in transformer disappointment.
Configuration/Manufacturing Errors - This incorporates conditions, for example, free or unsupported leads, free blocking, poor brazing, lacking center protection, sub-par hamper, and remote questions left in the tank.
Ill-advised Maintenance/Operation - Inadequate or inappropriate support and activity are a noteworthy reason for transformer disappointments. It incorporates separated or inappropriately set controls, loss of coolant, amassing of earth and oil, and consumption.
Outside Factors - Several outer elements like surges, fire blasts, helping and dampness can be set up as the reasons for the disappointment too.
Transformers Protection Best Practices
Transformer disappointments and security perils can be kept away from or limited by guaranteeing that the conductors and hardware are legitimately measured, ensured and enough grounded. Wrong establishment of transformers can result in flames from ill-advised security, and additionally electric stun from insufficient establishing.
*Once the transformer is set, the tank must be for all time grounded with an accurately estimated and legitimately introduced perpetual ground.
*Access ought to be confined to the transformer fluid filled compartment in states of inordinate dampness or rain.

* Dry air ought to be consistently directed into the gas space if mugginess surpasses 70%.
*Transformer ought to be given assurance against rain to such an extent that no water gets inside.
*All hardware utilized in the treatment of the liquid (hoses, pumps, and so forth.) ought to be spotless and dry. In the event that the protecting fluid for examination is drawn out, its level ought not go underneath the highest point of windings.
* Sufficient gas weight must be kept up to permit a positive weight of 1 psi to 2 psi consistently (even at low encompassing temperature) when fluid filled transformers are put away outside.
* Final investigation of the transformer is basic before it is invigorated. Every single electrical association, bushings, draw lead associations ought to be checked.
* Upon stacking the transformer ought to be kept under perception amid the initial couple of long stretches of task. All temperatures and weights ought to be checked in the transformer tank amid the primary seven day stretch of task.
* Surge arr esters must be introduced and associated with the transformer bushing/terminals with the briefest conceivable prompts shield the gear from line exchanging floods and lightning.So Our need to Transformer Protection.

Refrigeration Compressors


Refrigeration Compressors


Refrigeration compressors are a special type of compressor used for refrigeration, heat pumping, and air conditioning. Those compressors are large mechanical units, designed to be the core of industrial and air conditioning systems. Small, portable compressors do not fit into this category.

Refrigeration compressors are designed to turn low-pressure gases into high-pressure and high-temperature gases. Additionally, technically speaking, they are also used to maintain a low boiling point. This is achieved by removing vapor from the evaporator. There are three main types of refrigeration compressors.

Refrigeration Compressors

The first type of refrigeration compressor is the screw compressor. Screw compressors pass the refrigerant vapor through screw spindles. Each screw spindle compresses the intake of gas. Although there are refrigeration compressors with multiple spindles, most screw compressors have just two screw spindles.

The second type of refrigeration compressor is the scroll compressor. Scroll compressors achieve a lower rate of leakage and therefore are more efficient. They are the most common type of refrigeration compressors on the market.

The third type of refrigeration compressor is the piston compressor. These compressors achieve high pressure levels and are mostly used for commercial purposes. Piston compressors are also known as reciprocating compressors.

Though other types of refrigeration compressors exist aside from the main three described above, they fit only very specific situations and are usually not very effective. These types are less common and their usage is very rare.

To sum it up, refrigeration compressors are large modules aimed at refrigeration, heat pumping, and air conditioning of large facilities. They should not be confused with small, stand-alone compressors. The three main types are of refrigeration compressors screw compressors, scroll compressors, and piston or reciprocating compressors. Out of these three, scroll compressors are the most efficient, while reciprocating compressors are used for heavy industrial purposes.

Refrigerator Air Temperature Regulation


As the food inside your refrigerator gets colder and colder it radiates less heat to the air inside the refrigerator. The air temperature inside the refrigerator will remain colder as this process occurs. To regulate the temperature inside most refrigerators and freezers either a thermostat is used or a thermostat/control board combination.

Refrigeration Compressors

Thermostat Operation
A thermostat called a cold-control will cycle the compressor on and off to keep the temperature inside the refrigerator within a specified range. Typical average temperature settings of most refrigerators will be around 45 F. You can always adjust the fresh-food temperature setting by turning the dials on the cold control. Most cold-controls on Whirlpool, Maytag, Whirlpool, and GE refrigerators are located in the fresh-food side of the refrigerator, top and front near the interior light.

Thermostat/Control Board
A thermostat is an electrical device which changes resistance when a change in temperature occurs. Thermostats are typically mounted on the inside walls of the fresh-food compartment, and also the freezer compartment. The thermostat is connected electrically to the control board circuit. The firmware in the control board is designed so that resistance of the thermostat will correspond to a given temperature and will adjust fan speed, fresh-food damper door, and compressor operation to achieve the set temperature.

On most Whirlpool, Kenmore, Maytag, and GE refrigerators all the cold air for both the fresh-food compartment and the freezer compartment is produced by one evaporator, which is located behind the rear interior panel of the freezer compartment. Since the freezer air is so much colder than the fresh-food compartment, it is easy to see why it is logical to use this one evaporator to provide the necessary cold air for both the freezer and fresh-food compartments of most refrigerators.

Most of the cold air that is produced by the freezer/refrigerator evaporator circulates in the freezer compartment by the evaporator fan. The evaporator fan also circulates air to the ice maker and through the damper door to provide cold air to the refrigerator. Most of the damper door assemblies are located in the rear-top-left of the fresh food compartment. Only a small amount of cold air needed in the food compartment to keep it down to the proper temperature so the damper door will close when the proper temperature is reached. The control for this damper door is the other of the two dials within your refrigerator cold control or is adjusted via control board user interface.Refrigeration Compressors .





Radiator


Generator Set Cooling Systems
Radiator Design Considerations

Radiator cooling is the most widely recognized technique for cooling gen set motors. Basic and down to earth, they fit most applications' needs. All CAT gen sets can be furnished with different sizes of radiators mounted on the front of the unit. Notwithstanding, remote radiators can be utilized when sufficient wind current through the gen set walled in area isn't conceivable.

Most radiators are comprised of tubes encompassed by balances (the center) that concentrate warm from water pumped through the framework from the motor. Intended for 120 F surrounding temperatures, they work best when accurately coordinated to motor power, encompassing temperature and satisfactory wind stream.

Radiator

Radiator Selection Tips

Radiators ought to be estimated around 10 percent more prominent than the motor's warmth dismissal.

Elevation, air temperature and speed significantly influence cooling capacity and execution. Following are a few dependable guidelines that might be utilized by and large gen set cooling framework estimating works out:

For each 304.0m (1,000 feet) above ocean level, deduct 1.38C (2 F) from the watched encompassing temperature for a superior sign of the air's cooling capacity.

In encased zones with a motor mounted radiator, anticipate that surrounding temperature will increment as the air ignores the generator, motor and through the radiator. Table 1 records the assessed air to center temperatures ascends in various sorts of establishments.

Cooling capacity drops 1 C (1.8F) for each 10 percent expansion in glycol, up to 50 percent focus.

Clamor transmits for air delta and outlets, so position them far from commotion touchy zones.

Watch winning breezes that could cause deplete exhaust and warm or warmed outlet air to recycle to the channel as appeared in Figures 3A and B.

Position radiators from winning breezes so winds don't act against the fan, or introduce a windbreak a few feet before the outlet.

Utilize vast sweep turns and swinging vanes to limit disturbance and wind stream confinement on delta twists.

Table 1 – Estimated air to center temperature ascend with blower fan

Motor just, outside or in a vast motor room        3 C (5.4 F)

Motor/generator outside or in a vast motor room            4 C (7.2 F)

Motor/generator, in fenced in area with outside muffler               7 C (12.6 F)

Motor/generator, in fenced in area with interior muffler               9 C (16.2 F)

Motor mounted Units

Motor mounted radiators offer the least complex cooling framework. Industrial facility coordinated for the motor and application, planners and installers need to just stress over giving sufficient ventilation.

In walled in areas, radiator ducting ought to be bigger than the radiator center, with bay air conduits 1.5 times bigger than outlet air channels. In spite of the fact that louvers limit introduction to the components and vandalism, vent estimate must be expanded 25 percent since they repress air development, notwithstanding when completely open. These ought to mechanically, electrically or pneumatically controlled to completely open when the motor begins. Be that as it may, if units are practiced at no heap, louvers ought to consequently acclimate to keep up air temperature enabling the motor to warm to typical working temperature.

Radiator

Remote Radiators

In spite of the fact that remote radiators enable units to be set well inside a building, the warmth from motor task must be dispersed somewhere else. Be that as it may, framework configuration develops in multifaceted nature. Extra channeling and fittings add to starting expense and framework upkeep. In instances of long pipe runs, larger than usual channeling might be expected to meet stream prerequisites.

A few establishment indicates are one of a kind remote radiators. A remote radiator ought not be found more than 17.5m (57 feet) over the motor water pump. Something else, unreasonable head weight will probably cause the water draw seal to spill.

For establishments where the Radiator is mounted beneath the motor, a development tank is required. In the event that the extension tank is mounted on the motor, the radiator center must withstand full pump weight. This framework as a rule requires a round tube radiator. On the off chance that the radiator has a vertical center, invert water course through the radiator to take out any caught air in the gulf tank. E P G Designer can enable you to recognize the best segments for your establishments.

HVAC


Energy and HVAC Optimization

It’s talk about 30-40% of your electricity bill. That's how much it costs the average homeowner or commercial building owner to provide proper heating, ventilating, and air-conditioning (HVAC). A good HVAC system is the key to maintaining a comfortable, healthy and interior environment. Through the years, I have been asked by many owners for a strategy to reduce their cost of energy and HVAC. They don't want to sacrifice the interior environmental conditions, but they do want a point-by-point plan to follow. The interesting thing that often happens is that energy bills are lowered substantially and the HVAC system performance is improved. This is a standard function of any mechanical engineer specializing in energy and HVAC.

HVAC

The information on this page will help homeowners, building owners and building operators make informed decisions about existing HVAC systems or future upgrades.

Load Reduction

Control Systems
Operation and Maintenance
Load Reduction

The first step to achieve energy and HVAC system optimization is load reduction. This step normally consists of a long range plan which itemizes the actions to be taken based on best return on investment. Reducing your building load allows the existing HVAC system to operate more efficiently. If a new system or systems are being considered, it will be more cost effective to design for the reduced load as opposed to the existing load. A few common load reduction strategies include:

Tighten the building shell and add additional insulation. Adding insulation in existing buildings may not be achievable in some instances, so more consideration should be aimed at the exterior shell, especially windows and doors.
Installing energy-efficient windows. This is a big item on some buildings that still have single pane windows. The installation of double pane windows with a thermal break is a great return on investment. Make sure they are ENERGY STAR qualified windows. Tinting or Low-E coatings will even be better.
Upgrading lighting systems. The average commercial building has a lighting density of 2-3 watts per square foot which maintains proper lighting levels. This is a significant part of the HVAC load and almost any efforts in this direction will lower the cooling requirement for the building. Accent lighting (sometimes called architectural lighting) are not always energy efficient and should not be considered if you want to reduce energy and HVAC costs. Energy-efficient lighting systems emit less heat into conditioned space than older incandescent technology. If you have a return air plenum instead of return air ductwork, consider light twofers so that some of the heat from the lights is returned to the HVAC system instead of going into the occupied area.
Selecting efficient equipment and electronic devices that have a power saver option will reduce the sensible heat gain in the space. Items to consider include copy machines, kitchen equipment, computers and refrigerators.
Control ventilation by having your outside air balanced. Most building owners have drawings of the original HVAC system installation. Have the drawings reviewed by a mechanical engineer to confirm your outside air flow rates conform to the latest code requirements. If no drawings are available, your mechanical engineer should still be able to make recommendations for improvement.
Addressing these items is your first step to reducing energy and HVAC costs.

HVAC

HVAC Systems

The second step to achieve energy and HVAC system optimization is knowing your system. Your HVAC system is critical to your interior environment, but it also represents a large component of your utility expenses. While it is beyond the scope of this article to discuss every system, a few recommendations can be addressed. Every HVAC system component has increased in efficiency over the years. If your system is more than 13 years old, it's time to begin planning for an upgrade to new equipment. Well maintained residential systems have a life expectancy of about 15 years or so but seem to fail at the worse times. Have a replacement plan ready for the day your equipment fails.

Commercial systems vary, but if your building is using packaged equipment or split systems, the same lifetime can be expected. For larger commercial systems and industrial applications, the HVAC system may be more complex and require an individual analysis by a mechanical engineer. As I said, HVAC systems vary and no one-size-fits-all analysis works for larger systems. What all these systems have in common is they are normally fueled by electricity. Electricity cost money, so any efforts in the direction of increased efficiency is a plus

Nuclear power is one of the most discussed sources of energy nowadays. Nuclear energy is produced by nuclear fission or nuclear fusion of radioactive elements such as uranium. The process of nuclear energy production is free from carbon emission. So for this reason it is considered as an environment friendly energy source.

Nuclear energy is produced by certain chemical reactions. These reactions produce a huge amount of energy that is then converted to other forms of energy depending upon its required application. The reaction generally used to produce nuclear energy is nuclear fission. The fission reaction takes place within the nuclear reactor. Here the nucleus of the uranium atom is hit by some foreign neutron.
This causes the nucleus to break down into many small pieces and to release some free neutrons from it. The released neutrons hit the other uranium atoms and they break down. Thus a chain reaction takes place and huge amount of energy is released in the form of heat. This energy is then converted to other suitable forms if needed.
Nuclear Power

Nuclear energy is quite popular nowadays, notwithstanding tragic accidents which have occurred at nuclear power plants in the past. The most common source of energy today, however, is derived from fossil fuels. Due to the excessive use of these fossil fuels, it is predicted that their reserves will soon be exhausted.

So a new source of energy is needed badly to meet the needs of the current age. Beside this, there are also environmental concerns with the continued use of fossil fuels. The burning of fossil fuel releases carbon emissions into the air, which is harmful to the environment.
Many scientists believe this is increasing the temperature of the atmosphere of the whole world, as a result of what they call the greenhouse effect. The atmospheric pollutions produced from burning fossil fuels is also directly harmful to people and animals, having many adverse health consequences. Nuclear energy is free from emitting carbon products, so in this way it is friendly to the environment.
A nuclear power plant needs less substrate than the fossil fuel using power plant. So it has less fuel consumption too. The subject of the nuclear reaction is very sensitive, however, because the processed uranium can be used to produce the nuclear weapons and the nuclear waste is very harmful to the environment.

So, caution should be exercised when handling these materials. A nuclear power plant is also a sensitive place. Radiation leaks can occur anytime if there any kind of fault in the reactor, creating a hazardous situation for a potentially large geographical area.
Nuclear energy needs lot of technological support for production. Nations with the less technological advancement are unlikely to have the facilities and support to safely implement nuclear energy plants. Only a few countries in the world have already implemented nuclear power as a means of electricity generation.

World politics also presents an obstacle to the wide use of the nuclear power, as the supply of radioactive materials necessary to achieve the requisite reactions is subject to many restrictions.
So while from some angles it may seem that nuclear energy generation could be a perfect solution to the exhaustion of fossil fuels, there are quite a few objections to its immediate widespread usage.

3- Phase Induction Motor


         Industrial Star Delta Starter for a 3-Phase Induction Motor

Objectives of Star-Delta Technique Motor Starter are:
Reduce high starting current and along these lines forestall motor from overheating
Provide over-burden and no-voltage assurance
3- Phase Induction Motor

Star Delta Starter:
In star delta starting, the motor is connected in STAR mode throughout the starting period. When the motor reached the required speed, the motor is connected in DELTA mode.
Star Delta Motor Control Power Circuit
Star Delta Motor Control Power Circuit
Components of a Star-Delta Starter:
Contractors: The Star- Delta starter circuit comprises of three contractors: Main, star and delta contractors. The three contractors are solicited to unite the motor winding first in star and afterward in delta.

Timer: The contactors are regulated by a timer incorporated with the started.
By any chance if star and delta contactors are actuated at the same time, the motor will be damaged.
Thermal overload relay: A thermal over-load relay is likewise consolidated into star-delta control circuit to ensure the motor from intemperate heat which might expedite motor finding fire or wearing out. In the event that the temperature goes past a preset quality, the contact is open and power supply is cut in this manner ensuring the motor.

Working of Star-Delta Starter:
At first the primary contractor and the star contactors are shut. After a time interval the timer signs to the star contactor to head off to the open position and the primary, delta contactors to head off to the shut position, accordingly structuring delta circuit.
Hence, the line current drawn by the motor at starting is decreased to one-third as contrasted with starting current with the windings associated in delta. Likewise, since the torque advanced by an induction motor is corresponding to the square of the applied voltage; star- delta starter decreases the starting torque to one- third of that possible by immediate delta starting.
The timer controls conversion from star connection to delta connection. A timer in star delta starter for a 3-phase motor is intended to do the move from star mode, utilizing which the motor runs on a decreased voltage and current and produces less torque – to the delta mode indispensable for running the motor at its full power, utilizing high voltage and current to transform a high torque.

Terminal Connections in Star and Delta Configurations:
L1, L2 and L3 are the 3-phase line voltages, which are given to primary contractor. The main motor coils are U, V and W is shown in figure. In star mode of motor winding, the primary contractor associate the mains to essential winding terminals U1, V1 and W1.the star contractor shorts the auxiliary winding terminals U2, V2 and W2 as indicated in figure. Notwithstanding when the primary contractor is shut supply arrives at terminals A1, B1, C1 and consequently the motor winding are energized in star-mode.

The timer is initiated in the meantime moment when star contactor is energized. After the timer achieves the specified time period, the star contactor is de-energized and delta contactor is energized.

The point when delta contractor closes, the motor winding terminals U2, V2 and W2 get associated with V1, W1 and U1 individually through the shut contacts of primary contractor. That is for delta association, fulfilling end of one winding is to be joined with beginning end of the other winding. The motor winding are reconfigured in delta by supplying line voltage L1 to winding terminals W2 and U1, line voltage L2 to winding terminals U2 and V1; and line voltage L3 to winding terminals V2 and W1, as indicated in figure.3- Phase Induction Motor most of uses to Industrial work.
