Temperature shock test chamber concept and refrigeration system
Temperature shock test: used to test the degree of material structure or composite material that can be tolerated in a continuous environment of extremely high temperature and very low temperature in an instant, so as to test the chemical change or physics caused by thermal expansion and contraction in the shortest time. hurt. Used in electronic and electrical components, automation components, communication components, auto parts, metals, chemical materials, plastics and other industries, the physical changes of semiconductor ceramics and polymer materials, testing the material's repeated resistance to high and low temperature and products Chemical changes or physical damage produced by thermal expansion and contraction can confirm the quality of the product, from precision IC to heavy mechanical components, without the ideal test tool. Cooling System 3, refrigeration auxiliary parts: the main refrigeration accessories and control devices are imported originals. 4, refrigeration system and compressor: in order to ensure the test chamber cooling rate and minimum temperature requirements. The cascade system comprises a high pressure refrigeration cycle and a low pressure refrigeration cycle, the connection vessel being an evaporative condenser, and the evaporative condenser functioning as a condenser for the low pressure cycle. The design of the refrigeration system uses energy regulation technology, and an effective treatment method can ensure the energy consumption and cooling capacity of the refrigeration system can be effectively adjusted under the normal operation of the refrigeration unit, so that the operation cost of the refrigeration system And the failure has dropped to a more economical state.

1, cooling method: air cooling.
2. Refrigeration working principle: Both high and low refrigeration cycles adopt 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 work is consumed. The exhaust gas temperature is raised, and then the refrigerant is isothermally 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. This cycle is repeated to achieve the purpose of cooling.
