In every water cooled chiller, the liquid is separated from the refrigerant by sealed tubes or coils. Water is then passed through a series of sealed tubes in and around a compressed refrigerant of ammonia or Freon. The heat from the warmer water is passed through the metal sealing tubes and into the gas of the refrigerant which is then sucked off through the vessel by a compressor.
Air cooled chillers range in different sizes from the common cold drinking fountain to large industrial chillers that can accommodate thousands of gallons of liquid. Regardless of the size, water chillers all have the same function, which is to remove unwanted heat and cool down the liquid to a desired temperature. After removing the unwanted heat, the cooled chiller will discharge it elsewhere.
The refrigerant enters the heat exchanger in the form of a liquid and it comes in contact with the sealed tubes that contain the water and while this happens, it flashes into a gas. The flashing of the refrigerant happens when the heat is exchanged from the warmer water through the metal tubes and into the recirculating chiller. The heat, which is now in gas form, gets carried away by the suction of the compressor.
Through the operation of a fan, the machine’s condenser releases heat that was captured by the gas into the air. The gas then turns back into a liquid or condenses as it cools and then exits the condenser. The liquid refrigerant is then forced back into the heat exchanger vessel to perform the same work of removing heat from the warm water. This is the same process that is used on a refrigerator.
Always remember that proper maintenance on the chiller is needed to lengthen the appliance’s lifespan.
