-5 ℃ air-cooled screw chiller

-5 ℃ air-cooled screw chillerAir cooled flexible assembly, easy to install. No cooling tower required, suitable for use in water scarce areas or mobile environments. Based on factors such as environmental conditions, water quality, and production needs in various regions, our company offers a variety of models suitable for different locations, including shell and tube type, box type water pump with water tank type, titanium alloy type, stainless steel type, open type, screw type, split type, explosion-proof type, low-temperature type, and integrated cold and hot type

-5 ℃ air-cooled screw chillerIt is the low-temperature and low-pressure refrigerant gas sucked in by the compressor after evaporative refrigeration, and then compressed into high-temperature and high-pressure gas and sent to the condenser; After being cooled by a condenser, high-pressure and high-temperature gas condenses into a liquid at room temperature and high pressure; When the liquid at room temperature and high pressure flows into the thermal expansion valve, it is throttled into low-temperature and low-pressure wet vapor, which flows into the shell and tube evaporator, absorbs the heat of the chilled water in the evaporator, and lowers the water temperature; After evaporation, the refrigerant is sucked back into the compressor and the next refrigeration cycle is repeated to achieve the refrigeration purpose.

-5 ℃ air-cooled screw chillerThe compressor has a pair of helical teeth that mesh with each other and rotate in opposite directions. The rotor with protruding teeth is called a male rotor, and the rotor with concave teeth is called a female rotor. The teeth of the rotor are equivalent to the piston, and the working volume formed by the teeth of the rotor, the inner wall surface of the body, and the end caps at both ends is equivalent to the cylinder. There are suction and exhaust ports arranged diagonally at both ends of the body. As the rotor rotates inside the body, the working volume continuously changes due to the invasion or disengagement of teeth, thereby periodically changing the volume between each pair of teeth slots of the rotor to achieve the purpose of suction, compression, and exhaust. The rotor that meshes with each other has several identical working volumes that perform the same working process in sequence during each motion cycle. This working volume is called the elementary volume. It is formed by a pair of tooth surfaces in the rotor, the inner wall surface of the body, and the end cover. By studying the entire working cycle of one of the working volumes, one can gain a comprehensive understanding of the compressor's operation.
