The ozone-resistant aging test chamber is a commonly used experimental instrument and can be used in rubber products such as vulcanized rubber, thermoplastic rubber, cable insulation sheath and the like, and is widely used in various fields.
1. Refrigeration system and compressor. In order to ensure the requirements of the test chamber for the cooling rate and the minimum temperature, the refrigeration system of the test chamber adopts a cascade refrigeration system composed of imported compressors.
The refrigeration system has reasonable matching and high reliability. Easy to use and maintain, etc.
2. Refrigeration working principle. The refrigeration cycle adopts reverse card cycle, which consists of two isothermal processes and two adiabatic processes. The process is as follows: the refrigerant is adiabatically compressed to a higher pressure by the compressor, and the power is consumed.
The exhaust gas temperature rises, and then the refrigerant is heat-exchanged with the surrounding medium through the condenser to transfer heat to the surrounding medium.
After the refrigerant is adiabatically expanded by the shut-off valve, the temperature of the refrigerant is lowered. Finally, the refrigerant absorbs heat from the higher temperature object isothermally through the evaporator, so that the temperature of the object to be cooled is lowered. This cycle is repeated to achieve the purpose of cooling
3. Design and application of refrigeration system energy-adjusting technology. An effective treatment method can ensure the effective adjustment of the energy consumption and cooling capacity of the refrigeration system under the normal operation of the refrigeration unit, so that the refrigeration system operating costs have fallen to a more economical.
