The Essential Refrigeration & Air Conditioning Components, and What Do They Do?
Essential Refrigeration & Air Conditioning Components

Keeping your facility cool during the hot summer requires a well-functioning air conditioning system. Each Commercial HVAC unit comprises of components that work together to extract heat from the surrounding air and turn it into cold, refreshing air. It’s helpful to understand what these components are and how they work. When your chosen commercial heating and cooling company inspects your system, they run through all the parts to ensure they function correctly. Without regular inspections, you may find that your compressor breaks down, the fan motor stops, or something worse happens.

The Essential Components for HVAC Refrigeration and Air Conditioning

Upon inspection, a qualified HVAC technician will look over these main components: 

  1. Compressor: As the heart of the refrigeration system, this component compresses the refrigerant gas, which raises its temperature and pressure and circulates it through the system. It is located outside the facility.
  2. Condenser: The condenser receives the compressed refrigerant gas and releases the heat from it into the surrounding air. Since it is located outdoors with the compressor, hot air can dissipate easily. Additionally, the heated gas turns into a heated liquid in the condenser. 
  3. Evaporator: This equipment is located inside the facility and is responsible for helping the hot liquid evaporate back into a cool gas. Heat is extracted from the air passing over the evaporator.
  4. Expansion Valve: Before heading into the evaporator, the expansion valve reduces the pressure of the liquid refrigerant. The liquid changes into a gaseous state as it absorbs the heat from the air passing over the evaporator.
  5. Refrigerant: To work effectively, an air conditioning system needs a chemical that produces a cooling effect as it vaporizes. This chemical is called a refrigerant, the critical component the other pieces of equipment push through the system.
  6. Thermostat: This device monitors the indoor temperature and automatically adjusts it to ensure comfort within the building. There are many different types, including fully automated building automation systems.
  7. Fan motors: The system has several fans; the supply air fan moves the air across the evaporator and blows air throughout the ductwork. The condenser fan moves the air across the condenser coil outside. 
  8. Air filter: To keep air conditioning units functioning well, air filters block dust, pollen, and other debris from accumulating on the evaporator coil.
