Chiller working principle
The chiller unit consists of four main components: a compressor, an evaporator, a condenser, and an expansion valve, so that the cooling and heating effect of the unit is achieved.
Water chillers are commonly called freezers, refrigerators, ice water machines, freezers, coolers, etc. The use of chillers is widespread, so names are numerous. With the constant development of the chiller industry, more and more people are beginning to pay attention to any choice of the chiller industry which is increasingly important to human beings. In terms of product structure, "high energy efficiency than water-cooled screw units," "water source heat pump units," The highly competitive product structure consisting mainly of screw-type heat recovery units, "high-efficiency heat pump units", and "screw-type cryogenic refrigeration units" is a multifunctional machine that removes liquid vapors by compression or heat absorption. Refrigeration cycle. The vapor-compression chiller includes four main components of a vapor compression refrigeration cycle compressor, an evaporator, a condenser, and a partial metering device in the form of 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 equipment to be cooled in its respective space, and then the cooling water is redistributed back to the condenser 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 classified into water-cooled and air-cooled types depending on the type of refrigeration. Technically, water-cooled air-cooled air-to-energy ratios are 300 to 500 kcal/h higher than water-cooled. In installation, water cooling needs to be incorporated into the cooling tower before it can be used. Air cooling is removable without any additional assistance.
