As the key equipment of cold storage refrigeration system, compressor plays a core role in refrigeration engineering. Its main responsibility is to compress the low temperature and low pressure refrigerant gas returned from the evaporator, through this process, the mechanical energy is converted into the internal energy and pressure energy of the refrigerant, and the temperature of the refrigerant is significantly increased, and the state of high temperature and high pressure is changed.
According to the different working principle and structure, cold storage compressors mainly include rotor compressors, scroll compressors, screw compressors, and piston compressors.
Advantages of piston compressors
1, high efficiency. Piston compressors can be adapted to different refrigerants and have high efficiency, especially for small cold storage systems.
2. Strong environmental adaptability. Piston compressors can handle a very wide pressure range, suitable for cold storage applications requiring high pressure ratios, and can also be used in deep freezing or extreme temperature conditions; It can work in a large exhaust gas range, and can adapt to the refrigeration needs under different load and pressure conditions.
3. Low maintenance cost. Piston compressor service life, durable, and the compressor is easy to operate and maintain, easy to replace parts, and the market supply of parts.
