After more than 20 years of ups and downs, the company came to the fore in Rizhao City in 2000. At the beginning of its establishment, the company was less well-known and faced great competitive pressure. However, with solid professional knowledge and tenacious team cohesion, it moved forward steadily and down-to-earth. From the initial scale of a few people to the current team of nearly 100 people, the company has gradually expanded in scale and its business scope has gradually broadened. -

Screw unit refrigeration principle
Release time:
2024-05-27
The refrigeration principle of the screw chiller is mainly based on the vapor compression refrigeration cycle, which includes four basic steps: compression, condensation, throttling and evaporation. The following is a detailed description of these steps:
Compression process. After the refrigerant vapor in the evaporator is sucked into the screw compressor, the motor applies energy to it through the compressor rotor, so that the pressure of the refrigerant vapor increases and enters the condenser. At the same time, the temperature of the refrigerant vapor also increases accordingly at the end of compression.
Condensation process. The high-pressure and high-temperature refrigerant vapor from the compressor releases heat through the cooling water in the tube in the condenser, and the temperature drops. At the same time, it condenses into liquid at the saturated pressure (condensation pressure corresponding to the condensation temperature). At this time, the cooling water absorbs heat from the refrigerant vapor, and its temperature will rise.
Throttling process. When the high-temperature and high-pressure refrigerant liquid from the bottom of the condenser flows through the throttling device, it undergoes decompression expansion, and the pressure and temperature are reduced, becoming a low-pressure and low-temperature liquid and entering the evaporator.
Evaporation process. The low-pressure, low-temperature refrigerant liquid absorbs heat from the refrigerant (such as cold water) in the evaporator and evaporates into gas, while reducing the temperature of the refrigerant, thereby achieving artificial refrigeration. The refrigerant vapor in the evaporator is sucked into the compressor for compression, repeating the above compression, condensation, throttling, and evaporation process.
The screw compressor is equipped with a sliding valve mechanism inside it, which is used to control the suction flow of the compressor and the evaporation amount of the refrigerant, so that the cooling capacity can be adjusted steplessly within a certain range. In addition, the refrigeration power of the screw chiller is greater than that of the scroll chiller, and is mainly used in chemical plants, ink printing plants, automobile manufacturers, or central air-conditioning systems or other large-scale industrial refrigeration.
