The chiller consists of four main components: compressor, evaporator, condenser, and expansion valve, thus achieving the cooling and heating effect of the unit.
Chillers are commonly known as chillers, chillers, ice chillers, chillers, chillers, etc. Because of its wide use in all walks of life, there are so many names. With the continuous development of the chiller unit industry, more and more people are beginning to pay attention to any choice in the chiller unit industry. Human choice is becoming more and more important for human beings. In terms of product structure, "high energy efficiency ratio water-cooled screw unit", "water source heat pump unit", " "Screw heat recovery unit", "high-efficiency heat pump unit", "screw type cryogenic refrigeration unit", etc. are very competitive, its nature is a multi-functional machine, removing liquid vapor through compression or heat absorption refrigeration cycle. The vapor compression chiller consists of four main components: compressor, evaporator, condenser, and some metering devices. Different refrigerants are realized in the form of vapor compression refrigeration cycle. Absorption chillers use water as a refrigerant and rely on the water and lithium bromide solution to achieve a strong affinity for refrigeration. 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 air handling units or other types of terminal equipment for cooling in their respective spaces, and then the cooling water is redistributed back to the condenser to be cooled. In industrial applications, cooling pumps for chilled water or other liquids are passed through processes or laboratory equipment. Industrial chillers are used to control the cooling of products, mechanisms and factory machinery. The chiller can be generally divided into water-cooled and air-cooled according to the form of refrigeration. Technically, the water-cooled energy efficiency ratio is 300 to 500 kcal / h higher than that of the air-cooled. In installation, water cooling needs to be included in the cooling tower before it can be used. Air cooling is removable and requires no additional assistance.
