Most people who want to buy a chiller or want to know about an industrial chiller want to know how the chiller works, and they are also confused about the working principle of the chiller. How does the chiller work? What are the working principles of the chiller? Answer it for you now!
The water chiller uses electricity as the power source. The Freon refrigerant evaporates in the evaporator and absorbs the heat of the refrigerant water for cooling. The wet steam of Freon after evaporation and heat absorption is compressed into high temperature and high pressure gas by the compressor, and then condensed by the water-cooled condenser It becomes liquid and enters the evaporator through the expansion valve for recirculation. In this way, 7°C-12°C chilled water is prepared for air conditioning at the end of the air conditioner. Take a single-screw refrigeration compressor as an example: the meshing of an active rotor and two star wheels is used to generate compression. Its three continuous processes of suction, compression, and exhaust are realized by periodic volume changes when the rotor and star wheel rotate. The number of rotor teeth is six, and the star wheel is eleven teeth. The main components are a rotor, two star wheels, body, main bearing, and energy adjustment device. The capacity can be adjusted steplessly from 10%-100% and three- or four-stage adjustment. Compression principle: Inhalation process: gas enters the rotor cogging through the inhalation port. With the rotation of the rotor, the star wheel enters the state of meshing with the rotor tooth grooves in turn, and the gas enters the compression cavity (the enclosed space formed by the rotor tooth groove surface, the inner cavity of the casing and the tooth surface of the star wheel). Compression process: As the rotor rotates, the volume of the compression chamber decreases, and the gas is compressed until the front of the compression chamber turns to the exhaust port. Exhaust process: After the front of the compression chamber is turned to the exhaust port, the exhaust starts to complete a working cycle. Due to the symmetrical arrangement of the star wheel, the cycle will be compressed twice every time it rotates, and the displacement is correspondingly twice that of the aforementioned cycle.
