Water chillers are commonly known as freezers, chillers, chillers, chillers, chillers, etc. Because they are widely used in all walks of life, there are countless names. The principle of its nature is a multifunctional machine that removes liquid vapor through compression or heat absorption refrigeration cycles. The vapor compression chiller includes four main components of the vapor compression refrigeration cycle compressor, evaporator, condenser, and part of the metering device to realize different refrigerants. Absorption chillers use water as a refrigerant and rely on the water and lithium bromide solution to achieve a strong affinity for the cooling effect.
water chillers are generally used in air conditioning units and industrial cooling. In air-conditioning systems, chilled water is usually allocated to heat exchangers or coils 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 cooling to be cooled. In industrial applications, chilled water or other liquid cooling pumps are passed through processes or laboratory equipment. Industrial chillers are used in various industries to control the cooling of products, mechanisms and factory machinery.
According to the type of cooling, water chillers can be generally divided into water-cooled and air-cooled. Technically, the energy efficiency of water-cooled is 300 to 500 kcal/h higher than that of air-cooled; in terms of price, water-cooled is much lower than air-cooled; In terms of installation, water cooling needs to be incorporated into the cooling tower before it can be used, while air cooling is movable without other aids. However, air-cooled chillers only rely on fans to dissipate heat and have certain requirements on the environment: such as ventilation, humidity, and the temperature cannot be higher than 40. °C, pH value of air, etc.
