Your first impression when entering a building is the feeling of comfortability. Many people like to credit their HVAC unit for creating cool or hot air, but it actually functions to remove the undesired temperature from your indoor climate. This process can best be understood with a simplified explanation of the refrigeration process.

Traditional HVAC refrigeration systems are made up of 4 major components:

  • Compressor
  • Condenser Coil
  • Metering device
  • Evaporator Coil

The refrigeration process initiates when the compressor turns on, and its job is to create a pressure difference between the evaporator coil and condenser coil. These two coils work on opposite sides of the heat exchange process. The evaporator coil, more commonly known as the cool coil, is responsible for boiling the refrigerant into a cool vapor and send it to the compressor.

After the compressor receives the vapor from the evaporator coil, it increases the pressure to then discharge to the condenser coil. Due to the rise in pressure, the condenser coil temperature increases causing condensation to fall to the bottom of the condenser. This condensation is then transferred to the metering device to be cooled and transferred back to the evaporator coil.

Your HVAC system relies heavily on your evaporator coils and condenser coils for the entire refrigeration process to work. While all of your parts can be serviced by Wilmington Air, the wear and tear of these components should only be serviced by certified technicians who understand all of the latest techniques and regulations regarding refrigerant.
