The chiller is a modern and advanced refrigeration equipment. The chiller is an important auxiliary unit for industrial development. The chiller is a physical machine.

Chillers, commonly known as freezers, chillers, chillers, chillers, chillers, etc., are widely used in various industries, so the names are numerous. The principle of its nature is a versatile machine that removes liquid vapor through a compression or heat absorption refrigeration cycle. The steam compression chiller consists of four main components of a vapor compression refrigeration cycle compressor, an evaporator, a condenser, and a partial metering device to achieve different refrigerants. Absorption chillers use water as a refrigerant and rely on water and lithium bromide solution to achieve a strong refrigeration affinity.

The chiller is generally used in air conditioning units and industrial cooling. In an air conditioning system, chilled water is usually distributed to heat exchangers or coils in an air handling unit or other type of terminal equipment for cooling out of their respective spaces, and then the cooling water is redistributed back to the cooling and cooled. In industrial applications, chilled water or other liquid cooling pumps are passed through process or laboratory equipment. Industrial chillers are used in all industries to control products, mechanisms and plant machinery cooling.

The chiller can be generally divided into water-cooled and air-cooled according to the form of refrigeration. Technically, the water-cooling energy-efficiency ratio is higher than the kcal/h of 300 to 500; in terms of price, the water cooling is much lower than the air cooling; In the installation, water cooling needs to be included in the cooling tower before use, air cooling is movable, no other assistance is required, but the air-cooled chiller only relies on the fan to dissipate heat, which requires the environment: for example, ventilation, humidity, temperature can not be high 40 °C.
