Chillers Are Commonly Known As Freezers, Refrigeration Machines, Ice Water Machines, Frozen Water Machines, Coolers, Etc.

Chillers are commonly known as freezers, refrigerators, ice water machines, chillers, coolers, etc. Because they are widely used in various industries, they have countless names. Its nature principle is a multifunctional machine that removes liquid vapor through a compression or heat absorption refrigeration cycle. The vapor compression chiller consists of four main components in the form of a vapor compression refrigeration cycle compressor, evaporator, condenser, and part metering device to realize different refrigerants. Absorption chillers use water as the refrigerant and rely on a strong affinity between water and lithium bromide solution to achieve a refrigeration effect.

Chillers are generally used in air conditioning units and industrial cooling. In air conditioning systems, chilled water is typically distributed to heat exchangers or coils in air handling units or other types of terminal equipment for cooling in their respective spaces, and then the chilled water is redistributed back to the cooling units where it was cooled. In industrial applications, chilled water or other liquids are pumped through process or laboratory equipment. Industrial chillers are used in various industries to control the cooling of products, mechanisms and factory machinery.
Air-cooled chiller

Chillers can generally be divided into water-cooled and air-cooled types according to the refrigeration form. Technically, water-cooled energy efficiency is 300 to 500 kcal/h higher than air-cooled; in terms of price, water-cooled is much lower than air-cooled; In terms of installation, water cooling must be incorporated into a cooling tower before it can be used, while air cooling is movable and requires no other assistance. However, air-cooled chillers only rely on fans to dissipate heat and have certain environmental requirements: such as ventilation, humidity, and the temperature cannot be higher than 40°C. °C, air pH.
