Working principle of water chiller


The chiller consists of four main components: compressor, evaporator, condenser and expansion valve, thus realizing the refrigeration and heating effect of the chiller.

Water chillers are commonly known as chillers, refrigerators, chillers, freezers, chillers, etc. Because they are widely used in all walks of life, there are countless names. With the continuous development of the water chiller industry, more and more people begin to pay attention to any choice in the water chiller industry, which is more and more important for human beings. In terms of product structure, the most competitive product structure, such as "energy efficient water-cooled screw unit", "water source heat pump unit", "screw heat recovery unit", "efficient heat pump unit", "screw cryogenic refrigeration unit", is a multi-functional machine, The liquid vapor is removed through a compression or heat absorption refrigeration cycle. The steam compression chiller consists of four main components: the steam compression refrigeration cycle compressor, the evaporator, the condenser, and some metering devices to achieve different refrigerants. The absorption chiller uses water as refrigerant and relies on the water and lithium bromide solution between them to achieve a strong affinity for refrigeration effect. Water chillers are generally used for air conditioning units and industrial cooling. In the air conditioning system, the chilled water is usually distributed to the heat exchanger or coil in the air handling unit or other types of terminal equipment for cooling in their respective spaces, and then the cooling water is redistributed back to the condenser for cooling. In industrial applications, chilled water or other liquid cooling pumps are used through processes or laboratory equipment. Industrial chillers are used to control all walks of life for product, mechanism and plant mechanical cooling. Water chillers can generally be divided into water-cooled and air-cooled according to the refrigeration 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 cooling can only be used after being included in the cooling tower, while air cooling is movable without other assistance.
