Working Principle Of Chiller

The chiller consists of four main components: compressor, evaporator, condenser, and expansion valve, thus realizing the cooling and heating effect of the unit.
Chillers are commonly known as freezers, refrigerators, ice water machines, chilled water machines, coolers, etc. Because it is widely used in all walks of life, there are countless names. With the continuous development of the chiller industry, more and more people are beginning to pay attention to the fact that any choice in the chiller industry is becoming more and more important to humans. In terms of product structure, "water-cooled screw units with high energy efficiency ratio", "water source heat pump units", " Screw heat recovery unit", "high-efficiency heat pump unit", "screw cryogenic refrigeration unit" and so on are very competitive. The principle of its nature is a multifunctional machine that removes liquid vapor through compression or heat absorption refrigeration cycle. A vapor compression chiller consists of four main components: a compressor, an evaporator, a condenser, and a partial metering device, which implements different refrigerants in the form of a vapor compression refrigeration cycle. Absorption chillers use water as a refrigerant, and rely on a strong affinity between water and lithium bromide solution to achieve a cooling effect. Chillers are commonly used in air conditioning units and industrial cooling. In air conditioning systems, chilled water is usually 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 condenser to be cooled. In industrial applications, chilled water or other liquids are cooled by pumping through process or laboratory equipment. Industrial chillers are used in various industries to control the cooling of products, mechanisms and factory machinery. Chillers can generally be divided into water-cooled and air-cooled according to the cooling form. Technically, the energy efficiency ratio of water-cooled is 300 to 500 kcal/h higher than that of air-cooled; in terms of installation, water-cooled cooling towers can be used. Air cooling is removable without other assistance.
