To help you control the temperature inside of your business, you need a commercial HVAC system. While residential HVAC systems units are more compact to fit inside homes, commercial systems are built to heat or cool a much larger space.

What Is a Commercial HVAC System?

First things first, HVAC stands for heating, ventilation and air conditioning. An HVAC system provides heating and cooling within a space. A commercial HVAC system is used for larger spaces such as businesses, large enterprises, restaurants, etc. These systems are much more robust and require many different parts. A few of the main parts include:

  • Thermostat: The thermostat is what controls the HVAC system. It signals the system to produce heat or cool air depending on the temperature set.
  • Furnace: The furnace is the largest part of your HVAC system, providing the heat.
  • Heat exchanger: The heat exchanger is found within the furnace and is used to heat the air pulled in by the furnace.
  • Refrigerant lines: These lines turn refrigerant substances into liquid form.
  • Ductwork and vents: The ductwork and vents transfer heated or cooled air into your business or commercial building.

How Do They Work?

Your HVAC system facilitates three different processes including heating, ventilation and air conditioning. Each process requires its own individual unit that when together, creates your HVAC system, controlled by your central thermostat.

Heating

For HVAC systems with furnaces, the thermostat will start the heating process by signaling the furnace. A gas valve within the furnace will open to ignite the gas burner. Next, the heat generated from the burner is then used to heat the heat exchanger. The heat is then transformed into air as it flows through the exchanger.

Once the heat is turned into air, it is distributed using an internal motor and fan attached to the furnace. The heat is sent through the ductwork located throughout the commercial building.

Ventilation

HVAC systems would be pointless without proper ventilation. Ventilation allows the correct amount of fresh air to enter your commercial space, regardless of heating and cooling procedures. Without this fresh air, you could be subjected to odor, mold and other contaminants in the air.

It works by releasing harmful contaminants created during the heating and cooling process via flues and vent pipes, while allowing new air to enter in a controlled manner.

Cooling

Air conditioners within the HVAC system will use refrigeration to cool the air. Refrigerants, or substances used to absorb the heat, start in a gas form. A compressor is used to compress the gas, raising the temperature.

Once the gas is properly pressurized, it is transferred into a condensation coil, which releases the heat and changes the gas into a cooler liquid. Finally, a blower takes in the warm air and releases it over an evaporator. The liquid becomes a cooler gas again, absorbs the heat from the air and effectively cools it.

Proper Furnace Repair and Your HVAC System

As the largest part of your HVAC system and one of the most important, your furnace should be in good repair at all times. Proper commercial HVAC maintenance should be scheduled to ensure your furnace is in good working order. Issues such as cracked heat exchangers and excess carbon monoxide can have serious effects on the HVAC system in its entirety.

All three systems in your HVAC system rely on each other for proper temperature regulation and ventilation. Your furnace and other parts of your HVAC system should be serviced at least once per year to protect your commercial property.
