The Basic Components of Commercial HVAC Systems

The Basic Components of Commercial HVAC Systems

When it comes down to your commercial HVAC systems, it is important to understand the basics.

When it comes down to your commercial HVAC systems, it is important to understand the basics. Hopefully, you will not ever have to deal with your HVAC unit’s problems, but if it does have issues, it will be beneficial to have some knowledge of the very basic components. While you probably still have to call in the professionals, this guide will help you see who has to be called, how quickly, and how to protect your HVAC systems.

Furnace Heating with Your HVAC Systems

Your furnace is the primary heating system of your HVAC system. Both commercial and residential buildings will have furnaces, but the furnace will be a lot more powerful for larger commercial buildings. The furnace uses energy to heat the air before moving it all throughout your building. All of this is activated by a pilot light. Once you alter the temperature, the pilot light will then turn on, setting off the burners. The heat that is created by these burners is then blown through a heat exchanger before it is then moved throughout the entire building by a blower motor. This process continues until the desired temperature throughout the building by your blower motor. This process will keep up until the desired temperature has been reached, at which point your system will shut off.

If you own an electric furnace, it functions differently. Electricity passes through the heating elements to start instead of using a pilot light. These heating units are attached to resistance coils, which then leads to blower motors.

Air Conditioning Components

The cooling components of your HVAC unit is more simply called the air conditioning unit. In many businesses, this is important to the safety and well-being of your employees and equipment, especially if you work within an industry with more heat-sensitive items. There are four main aspects to your air conditioner, the condenser, compressor, evaporator, and expansion device. Both the cooling and heating are pumped through the building with the assistance from the heat pump. Your heat pump will need either a ground source, water source, or air source to work properly.
