Industrial water chillers are physical machines.
Industrial water chillers are commonly known as refrigerators, refrigerators, water chillers, water chillers, and chillers. Due to their wide use in various industries, their names are countless. The principle of its nature is a multifunctional machine that removes liquid vapor through a compression or heat absorption refrigeration cycle. The steam compression chiller consists of four main components: a steam compression refrigeration cycle compressor, an evaporator, a condenser, and some metering devices to achieve different refrigerants. Absorption chillers use water as a refrigerant and rely on the water and lithium bromide solution between them to achieve a strong affinity for refrigeration.
Industrial water chillers are commonly used in air conditioning units and industrial cooling. In air conditioning systems, chilled water is typically distributed to heat exchangers or coils for cooling in air handling units or other types of terminal equipment in their respective spaces, and then the cooling water is redistributed back to be cooled down. In industrial applications, cooling pumps for chilled water or other liquids are provided through process or laboratory equipment. Industrial water chillers are used to control products, mechanisms, and plant mechanical cooling in various industries.
Water chillers can generally be divided into water cooled and air cooled according to their refrigeration forms. Technically, the energy efficiency ratio of water cooling is 300 to 500 kcal/h higher than that of air cooling; In terms of price, water cooling is much lower than air cooling; In installation, water cooling needs to be incorporated into the cooling tower before it can be used, while air cooling is movable without other assistance. However, air cooled water chillers rely solely on fans to dissipate heat, and have environmental requirements: for example, ventilation, humidity, temperature not higher than 40 ° C, air pH
