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.

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

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.

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

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.

Induction motor winding terminals connected in star and delta configuration

Induction Motor Winding Terminals Connected in Star and Delta Configuration

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.
