What are HVACs?

HVACs are heating, ventilation, and air-conditioning systems. HVACs are involved in the process of exchanging or replacing the air in a space to provide good indoor air quality. They control the temperature, replace the oxygen, remove smoke, odors, moisture, dust, bacteria, and carbon dioxide. HVACs also keep the air circulating and prevent stagnant air. They are designed to operate at peak load. However, this only happens for a short time in the whole year. As a result, much energy is wasted in ventilation and air-conditioning applications. HVACs provide thermal comfort and good air quality, but it is important that they are energy-efficient.

Some HVACs can use natural sources of energy such as ground energy or solar power. These kinds of systems are kinder to the environment,

Settings, where HVACs are used, include:

  • Homes

  • Apartment buildings

  • Hotels

  • Care homes

  • Industrial buildings

  • Office buildings

  • Hospitals

  • Cars

  • Trains

  • Airplanes

  • Submarines

  • Ships

There are several parts to a typical HVAC system

Air Return

The air return is the part of the system that marks the beginning of the ventilation cycle. This return sucks in air, draws it through a filter, and then passes it into the main system.


The filter is the second part of the air return that draws air through it.

Exhaust Outlets

The exhaust outlets are where the exhaust created by the heating system is pushed out.


The ducts are the channels through which the air passes.

Electrical Elements

This part of your system can be the source of problems. Regular maintenance is essential.

Outdoor Unit

The outdoor unit houses the fan which provides airflow.


The compressor converts the refrigerant from a gas to liquid and sends it to the coils.


The coils cool the air as it passes through with help from the refrigerant.


The blower draws in warm air through the unit.

HVAC Drives

It is becoming ever more essential to save energy with HVAC applications due to cost and environmental considerations. Most systems use a motor. A way to improve energy efficiency is to run the motor with a variable frequency drive or VFD. The VFD adjusts the speed of the motor depending on the requirements and operations schedule. This precise control saves on energy consumption. Therefore, the entire system is more energy- efficient.

Electronic and control technology has been advancing greatly in recent years. As a result, the variable speed drives used for HVACs have improved in performance. They are now used more frequently in heating, ventilation, and air-conditioning systems. The drive changes the motor speed smoothly and within a broad range. This reduced motor speed also lessens motor power which in turn saves energy and therefore money.

With an HVAC drive, your clients can stay comfortable while also saving money, helping the environment, and reducing CO2 emissions. The VFD also keeps you compliant with environmental regulations across the world.

The increased control of the motor that a drive brings means that there is less waste of power. The components in the system also receive less wear and so will last longer, reducing maintenance costs.

Many models of HVAC drive can operate in tough environments, able to withstand extremes of heat and cold. It is also possible to run multiple motors from a single drive. The drive can work with a variety of motors so you can choose which one you prefer for your unique situation.
