HVAC systems are essential in commercial buildings such as hospitals, restaurants, hotels, banks, gas stations, office buildings, schools, and other commercial buildings. These commercial buildings require well-performing HVAC systems to keep occupants cozy and happy throughout the season, even when it is a steamy hot summer or a freezing winter.
But how does an HVAC system work? First, it is important to understand how the commercial HVAC system works to select the right one for your commercial needs.
What Is an HVAC System?
HVAC stands for heating, ventilation and air conditioning. The HVAC system plays a significant role in commercial buildings by controlling humidity, temperatures, and air conditioning through heating and cooling. This creates a comfortable environment for all occupants considering many commercial buildings host many people.
Notably, these systems are highly popular due to their ability to use fresh air from outside to provide high indoor air quality in commercial buildings.
How Does an HVAC System Work?
The HVAC system has three main functions:
- Cooling
- Heating
- Ventilating
Even though each process requires its own individual unit, they are all interconnected and controlled by a central thermostat.
Cooling
The air conditioner within the HVAC system uses refrigeration to cool the air. The standard process for conditioning and cooling the surrounding air will look something like this:
- First, refrigerants absorb heat from the air.
- Next, the compressor pressurizes the gas, raising temperatures.
- Once the gas is compressed, it is transferred to the condensation coil, which releases heat and changes the gas into a cool liquid.
- The blower then takes in warm air and releases it over an evaporator, and the liquid becomes a gas again, absorbing heat from the air and effectively cooling it.
Heating
During the heating process, your HVAC system will use heat pumps to extract heat from the air before distribution. A typical heating process will look something like this:
- The thermostat starts the heating process for HVAC systems with furnaces by signaling the furnace.
- A gas valve opens to ignite the burner, and the heat from the burner is used to heat the heat exchanger.
- The heat is transformed into air as it flows through the exchanger.
- The heated air is then distributed using a fan attached to the furnace and ductwork throughout the commercial building.
Ventilation
Ventilation is an essential and necessary part of an HVAC system. It removes harmful byproducts that are created by the combustion process and keeps the air quality fresh.
Without proper ventilation, the indoor air quality will become stuffy, odors will linger, and mold or mildew will develop quickly and easily.
