Tips to Optimize HVAC Systems

Tips to Optimize HVAC Systems

Complaining about the temperature in your room to be overly hot or too cold, won’t get you anywhere. To ensure your HVAC system performs well all the time, it is necessary to optimize it properly.

Here are a few tips:

Calibrate thermostats
Thermostats that aren’t correctly calibrated read and adjust to the wrong temperature, so the heating or cooling is never to your satisfaction. That is why you need to ensure that thermostats are calibrated accurately.

Repair economizers
Economizers on air handling equipment might not work correctly or stop functioning. Faulty controls or slipped linkages cause the dampers to get stuck in one position. A DIY fix by sticking a 2×4 into the outside air damper to keep it open, until the repair can be made, is fine, but you have to actually repair it (forgetting won’t do).

Submetering
When buildings have only one electric meter, it causes a huge strain on the HVAC system. Sub-metering the lighting, HVAC system, and plug loads show which areas use more energy, so you can address the problem areas accordingly and fix small issues before they become major ones.

Cleaning coils
HVAC coils get dirty, and the buildup of dirty and hazardous biofilm makes the system work harder than normal, reducing its efficiency. Dirty coils can also diminish indoor air quality and make people sick. You need to hire a professional who can clean the coils thoroughly with proper equipment and specialized steam solution that gets deep into the coils.

Operating time
Equipment that should run only during normal operating hours, but instead runs constantly, wastes a lot of energy. Lights, air handling systems and pumps, as well as personal use equipment such as computers, chargers, heaters or small fans under or on top of desks, all have the potential to be left on 24/7. Install timers or motion sensors on lights and use programmable thermostats everywhere you can. Remember to switch off fans, computers, etc. when you step out.

Repair variable frequency drives
These can be excellent energy savers as they modify the speed of the motor they are serving depending upon the requirements of the system. The energy savings is proportional to the cube of the rpm. But if these drives malfunction and aren’t repaired in time, the motor keeps running at full rpm, squandering its energy saving capabilities, and possibly causing additional problems. Never put variable frequency drives on bypass and repair the problem ASAP.

These pointers will come in handy for optimizing HVAC systems and maintaining a comfortable ambience at home.
