What is the difference between an air-cooled screw chiller and a water-cooled screw chiller - oumalchiller.com

 Both air-cooled screw chillers and water-cooled screw chillers use semi-hermetic screw compressors, and screw compressors have a high energy efficiency ratio. At present, the compressors of screw-type industrial chillers mostly use compressor brands such as Hanbell Bitzer, Fusheng, and Refcomp and other compressor brands. The main difference between the air-cooled screw chiller and the water-cooled screw chiller is the form of heat dissipation. The air-cooled screw chiller uses a fan to dissipate heat, uses air as the cooling medium, and dissipates heat through the air through a fin condenser and a low-noise fan. To cool the refrigerant, the water-cooled chiller uses water as the cooling medium, and then the cooling water cools the refrigerant.


Secondly, the installation of the air-cooled screw chiller is simple and does not require a cooling tower. Because the screw chiller machine is relatively large, an external water tank is used. The air-cooled screw chiller is greatly affected by the ambient temperature, especially in some areas with high ambient temperature, which will cause poor cooling effect and may cause a high-pressure alarm due to excessive temperature. As the air-cooled screw chiller’s water quality requirements are small, so we recommend installing an air-cooled screw chiller where the water quality is not good. The water-cooled screw chiller is not affected by the environment, and the cooling effect is better than the air-cooled screw chiller. In the case of the same cooling capacity, due to the lower condensing temperature of the water-cooled screw chiller, higher cooling effect, lower power and lower power consumption, the operating cost of the water-cooled screw chiller is lower than that of the air-cooled screw chiller machine.


Therefore, when purchasing a screw chiller, whether to choose an air-cooled screw chiller or a water-cooled screw chiller requires us to consider the environment, installation, and cost. If you are still hesitating about how to choose a chiller, contact us and a professional refrigeration engineer will give you advice. Email: oumal@oumal.com.

Where are water-cooled chillers used？ What is a chiller used for?

  Water-cooled chiller   is a cooling water device that can provide constant temperature, constant current and constant pressure. A chiller is a machine that achieves refrigeration through vapor compression or absorption cycles. These liquids can flow through heat exchangers to cool the air or equipment. The industrial chiller can always output ice water with a lower temperature than the ambient temperature. It can be used wherever cooling is required, either direct cooling or indirect heat exchange. The main components of a water-cooled chiller are compressor, condenser, evaporator, water pump, and water tank. Chillers have a wide range of applications. The chiller can be used to cool the injection mold, improve the quality of plastic products, cool the vacuum coating, control the temperature of the vacuum coating machine, cool the food industry, fast cooling processing, chemical industry, effectively control the temperature of chemicals, cooling buildings, concrete fast Cool...
