Working of an HVAC System – Find out from Experts

Winter Season

Almost every house in Canada has an installed HVAC system, and for those who don’t, this article is for you. HVAC, heating ventilation and cooling provides thermal heat, cleans the air, and equips cool air depending upon the user’s requirements. They are installed in houses, offices, theatres, malls, stores, factories etc. Like any other inbuilt machinery, efficient HVAC systems are established by skilled and registered technicians. Other than just cooling, heating and ventilating the area where they are installed, this equipment serves additional benefits too. Some of them are:

Let’s look into the working of HVAC units.

 

How Does An HVAC System Work?

 

The working of the HVAC system is a bit complex. Every HVAC system serves three essential functions: providing indoor air quality, cooling, and heating with thermal power. These three functions are interrelated and work co-dependently. To understand the functioning, understanding the parts of the system are essential. There are nine basic elements of an HVAC unit. These are:

 

Electrical Components

Electrical components are the electric loads that convert electricity into mechanical energy like thermal heat or condense the air. The main elements in the HVAC system are

The electrical components are prone to go wrong first and then damage the other parts.

 

Compressor

The compressor works as an outdoor unit of the system. It compresses and converts the refrigerant gas into a liquid to increase its temperature, and once it is heated, the gas exits the compressor. After that, it enters the condenser, where the cooling takes place.

 

Air Return

Air return is the point where ventilation begins. The air is sucked and drawn out through a filter. Finally, it is passed to the primary system. Air returns or ventilation can be affected by dust and debris. So regular cleaning and servicing of these units can help you to make healthy use of the technology and increase its life span.

 

Filter

A filter is the secondary part of the air return. It is the part through which the air is drawn. Keeping the filters and air return clean will help you elongate the unit’s lifespan and maintain its functioning.

 

Exhaust Outlets

The air that is compressed into thermal heat or condensed to form cooling air also needs a path to exit. This path is called an exhaust or exhaust outlet. It can be a chimney or a vent stack etc.

 

Duct

A duct in an HVAC system is a passage used to pass, deliver, remove, and return the air. It also helps in air exhaustion. In order to keep them working, cleaning the ducts annually will help you save on extra HVAC maintenance costs.

 

Coils

A coil has two types of working in an HVAC system. The first is to absorb the inner heat of the area. It is situated in the air handler and attached to the furnace. As for condensing, it completes the heat exchange process to produce cool air.

 

Blower

The HVAC blower draws in warm air via the main section of the unit sends conditioned air from the furnace into the home or vice versa. The blower motor passes the duct system and then spreads across the house or the building.
