Rubber ozone testing machine, ozone resistance test box machine, ozone resistance testing machine refrigeration principle: 01.The refrigeration cycle is composed of two isothermal processes and two adiabatic processes. The process is as follows: the refrigerant is compressed to a higher pressure by the adiabatic compression of the compressor, and the exhaust temperature is increased when the work is consumed.The refrigerant is then transferred to the surrounding medium by heat transfer through the condenser and other media. 02.The refrigerant temperature is reduced when the latter refrigerant works through the closure valve thermal expansion.Finally, the refrigerant absorbs heat from the higher temperature through the evaporator, which reduces the temperature of the cooled object.This cycle is repeated in order to achieve the purpose of cooling down. 03.The design of refrigeration system applies energy regulation technology, an effective treatment method can not only guarantee the refrigeration unit in normal operation, but also can effectively regulate the energy consumption and refrigerating capacity of the refrigeration system.The operating cost of the refrigeration system is reduced to a more economical state.
