CO2 compressor principle

From the compressor application industry, the compressed air industry includes machinery, automobiles, electronics, electric power, metallurgy, mining, construction, building materials, petroleum, chemical, petrochemical, textile, environmental protection, military industry and other industrial and civil fields. All areas of production and life. Compressed air is an important source of energy industrial products. It is also known as the \"source of life\" for the production of industrial products.

There are many types of air compressors, which can be divided into three categories according to their working principles: volumetric, dynamic (speed or turbine) and thermal. In positive displacement compressors, the increase in pressure is achieved by relying on direct compression of the gas volume. In a power compressor, the impeller rotates at a high speed to increase the pressure and speed of the gas, and then in the fixed element, a part of the speed can be further converted into the energy of the gas pressure. The jet is a thermal printer. It uses a high-speed gas or steam jet to carry inwardly flowing gas, and then converts it into pressure energy at the speed of the diffused mixture.

The best function of CO2 compressor

Compared with ordinary refrigerant compressors, CO2 compressors have high working pressure, large pressure difference, small pressure ratio, small volume, light weight, difficulty in controlling the clearance of moving parts, and difficult lubrication characteristics. Therefore, the development of carbon dioxide compressors has always been a difficult point in the development of refrigeration technology. Various scientific research institutes and refrigeration equipment companies have developed many types of compressors at home and abroad. Due to the environmental advantages of CO2 in automotive air conditioning applications, CO2 automotive air conditioning compressors have also been studied and developed through various refrigeration companies and vehicle companies.

Excellent application of CO2 compressor

1. In the application of automotive air conditioning, at this time, when the air conditioning system is operated under transcritical conditions and its working pressure is high but the compression ratio is low, the relative efficiency of the compressor is high; excellent heat transfer and the thermodynamic properties of supercritical fluid make it The efficiency of becoming a heat exchanger is also very high, which makes the air conditioning system more energy-efficient and can compete with conventional refrigerants (such as R12, R22, etc.) and other existing alternatives (R134a, R410A, etc.). For the development of electric vehicles, the characteristics of carbon dioxide heat pumps can also solve the defect that modern automobile air conditioners cannot provide sufficient heat to the car in winter. Through a large number of experimental studies, it has been shown that the CO 2 transcritical cycle is used for vehicle air-conditioning, which not only has the advantages of environmental protection, but also has a whole body efficiency.

2. Used in various heat pumps, especially heat pump water heaters. At this time, the heat pump system is also operating under transcritical conditions, and the advantages of compressors and heat exchangers still exist; the most important change in the gas cooler CO2 is suitable for water heating, so that the heat pump is more efficient And can compete with conventional refrigerants (R134a, R410A, etc.). Through the research of CO2 heat pump, not only CO2 emissions can be reduced, but also the heat pump has high performance and has broad application and development prospects.

3. Application in cascade refrigeration system. At this time, CO 2 is used as a low-temperature refrigerator, and high temperature is used NH 3 or R290 as a refrigerant. Compared with other low-temperature refrigerants, even at low temperatures, CO 2 has a very small viscosity, good heat transfer performance, and considerable freezing capacity.

At present, in China, NH/CO2 cascade refrigeration system, and NH3 as the refrigerant, the cooling system with carbon dioxide as the refrigerant has been widely used in logistics engineering, poultry processing, ice making, conditioning ingredients and aquatic products. application.
