What is an air chiller

A chiller that relies on a building’s air handler system to cool fluids is an industrial air-cooled chiller. Chillers rely on four main parts: an evaporator, compressor, condenser, and expansion valve.

A chiller uses air-cooling technology to remove the heat from the purified water. Through an air handler, the water is heated before being recirculated to the chiller. The chiller’s evaporator is responsible for cooling the liquid within. As the liquid refrigerant travels through the evaporator tube, it evaporates, converting it into a low-pressure gas. The compressor then converts the refrigerant gas from low pressure to high pressure. As soon as the gas is released, it is routed via condensers that use air as a cooling medium. Fans on the side of the chiller work to dissipate any remaining heat while it is in the condenser. To get the most out of your chiller, you should put it somewhere cool and airy that isn’t impacted by the additional heat it will produce, like the great outdoors. When the refrigerant exits the condenser, it becomes a high-pressure liquid. The under-pressure liquid is sent to the evaporator through an expansion valve. During this process, the refrigerant changes from a high-pressure liquid to a low-pressure liquid, a phase transition. At reduced pressure, this liquid is recycled back to the evaporator.

Outdoor retail centers and amusement parks depend on industrial chillers just as much as hotels, indoor shopping malls, hospitals, and massive industrial buildings. Portable air-cooled chillers might be helpful for large events or unanticipated crises.

The Workings of Air-Cooled Chillers

  • Air-cooled chillers take heat from treated water as their fuel source. As the water in the air handler system is used, it is cycled back to the chiller. Chiller water is cooled by passing it through an evaporator. Low-pressure gas is created when liquid refrigerant evaporates over the evaporator tube. After that, the refrigerant that has disappeared is transferred to the compressor. The compressor works to increase the pressure of low-pressure gas.
  • The condenser’s built-in chiller is cooled by expelling waste heat to the outside through fans. The released gas will go to the air-cooled condensers. Outdoors or in a huge room are the two best options for positioning the chiller. This is because the chiller vents the surplus heat away, lowering its overall effect.
  • The refrigerant changes from a gas to a high-pressure liquid as soon as the gas leaves the condenser. After passing through the expansion valve, the high-pressure liquid reaches the evaporator. During this process, the refrigerant undergoes a phase transition from a high-pressure liquid to a low-pressure liquid.
  • Everything goes through a full circle again at the evaporator. This low-pressure liquid will be recycled back to the evaporator since the principle of operation for an industrial air-cooled chiller is also based on a continuous cycle.
