What is a water cooled chiller system?


Water chillers are commonly called freezers, refrigerators, ice water machines, freezers, coolers, etc. The use of chillers is widespread, so names are numerous. The principle of its nature is a versatile machine that removes liquid vapors through compression or heat absorption refrigeration cycles. The vapor compression chiller includes four main components, a vapor compression refrigeration cycle compressor, an evaporator, a condenser, and a partial metering device, thereby realizing different refrigerants. Absorption chillers use water as a refrigerant and rely on water and lithium bromide solutions to achieve a very good refrigeration affinity. 


Chillers are generally used in air conditioning units and industrial cooling. In air-conditioning systems, chilled water is usually distributed to heat exchangers or coils in an air handling unit or other type of terminal device to cool in its respective space, and then the cooling water is redistributed back to the cooling to be cooled. In industrial applications, cooling water for chilled water or other liquids is passed through a process or laboratory equipment. Industrial chillers are used in various industries that control the cooling of products, mechanisms and factory machinery.


Chillers can generally be divided into water-cooled and air-cooled types depending on the type of refrigeration. Technically, water cooling is 300 to 500 kcal/h higher than air-cooled energy efficiency. In terms of price, water cooling is much lower than air cooling. In the installation, the water cooling needs to be incorporated into the cooling tower before it can be used, and the air-cooling is removable without additional assistance. However, the air-cooled chiller only uses the fan to dissipate heat and has certain requirements for the environment: for example, ventilation, humidity, temperature can not be higher than 40°C, air pH value...
