The chiller is a number of compressors working in parallel in the form of chiller organizational work structure, so as to achieve high efficiency cooling output.
The chiller is a physical machine.
Chiller is commonly known as freezer, refrigerator, ice water machine, freezing water machine, cooling machine, etc., because of the wider use of all walks of life, so the name is more than countless. The principle of its nature is a versatile machine that removes liquid vapor through a compression or thermal absorption refrigeration cycle. Vapor compression chiller consists of four main components of the vapor compression refrigeration cycle in the form of compressor, evaporator, condenser, and part of the metering device thereby realizing the different refrigerants. Absorption chillers utilize water as the refrigerant and rely on a strong affinity between the water and the lithium bromide solution to achieve the cooling 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 to be cooled off. In industrial applications, chilled water or other liquids are cooled by pumping them through process or laboratory equipment. Industrial chillers are used in a variety of industries to control the cooling of products, mechanisms and plant machinery.
Air-cooled chiller
Chiller according to the form of refrigeration can generally be divided into water-cooled and air-cooled, in technology, water-cooled than air-cooled energy efficiency than to be higher than the 300 to 500 kcal / h; in the price, water-cooled than the air-cooled much lower; in the installation, the water-cooled need to be incorporated into the cooling tower can be used, the air-cooled is movable without other assistance, but air-cooled chiller is only by virtue of the Fan cooling, the environment has requirements: such as ventilation, humidity, temperature can not be higher than 40 ° C, air pH ...
