A commercial HVAC system is a complex network of different components working together to provide thermal comfort to the inside of your building. Each of these components play a vital role in the heating, cooling, ventilating, and movement of air into your building. And while you aren’t expected to know every detail about the operation of your HVAC system, it is important to have a general idea of what parts of the system need to be checked regularly as part of your HVAC maintenance plan.

Air-rite Solutions are experienced HVAC experts who have been helping commercial and industrial businesses throughout South East Queensland design, supply, install, and maintain their air conditioning systems. We are well equipped with knowledge on the inner workings of a commercial HVAC system.

Today, we are going to take you through the basics of how a commercial HVAC system works and what you can do to help it run at peak efficiency.

The Basic Components of a HVAC System

Before we dive into the actual operation of a HVAC system, it’s best if we start by discussing the basic components that make up a system. Each of these different parts work seamlessly together to provide the air regulation that allows for indoor comfort. There are nine main components that make up a HVAC system, and we are going to look at each of them.

1.        Air return

This component is what draws the outside air and returns it back into the main system through filters.

2.        Air filters

The air filters are important for keeping out dust and other contaminants from entering the main system and should be cleaned regularly.

3.        Compressor

The compressor plays an important role in converting the refrigerant into liquid so it can regulate the coils.

4.        Coils

These components are responsible for absorbing the indoor heat.

5.        Exhaust outlets

Provide an exit point for all the hot air in your system to be vented out.

6.        Ducts

The transporters of air that move it around your commercial building.

7.        Outdoor unit

This unit is responsible for transferring indoor heated air outside.

8.        Blower

The blower is what moves the cooled or heated air into your indoor space.

9.        Electrical components

The various inner electrical parts that are responsible for the efficient operation of your system.

The next time you have your commercial air conditioning system assessed by a HVAC technician, ask them to check each of these different components to guarantee a healthy and reliable system.

The Basics of How a HVAC System Works

At its core, a commercial HVAC system works by regulating the temperature and quality of the indoor air. During the summer months when you want to cool down your building, the refrigerant inside your system is cooled into a liquid while inside the coils. When the warmer air comes into contact with these cooled coils, the air itself lowers in temperature and is transported through the ductwork to the relevant room.

In winter, when you need to warm up your indoor space, a furnace consumes either gas, oil, or electricity to produce heated air to your building.

A centralised commercial HVAC system is therefore responsible for both the cooling and heating of air around a building. The scale obviously differs significantly depending on the type of building, but whether that’s an office block, restaurant, retail store, factory, or school, the basic fundamentals remain the same.
