Introduction and function principle of high and low temperature alternating test chamber


High and low temperature alternating test chamber is an essential test equipment for aviation, automobile, home appliance, scientific research and other fields. It is used to test and determine the parameters of electric, electronic and other products and materials after high temperature, low temperature, or constant test temperature environment changes. And performance.
The high and low temperature alternating test chamber is used to simulate the product under the combination of temperature and humidity in the climatic environment (high and low temperature operation, storage, temperature cycle, high temperature and high humidity, low temperature and low humidity, condensation test, etc.), applied to the defense industry, aerospace industry, automation Test specifications for components, automotive parts, electrical and electronic components, instrumentation, materials, plastics, chemicals, food, pharmaceutical industry and related products for heat resistance, moisture resistance, cold resistance, dry resistance and quality management engineering Evaluate whether the adaptability and characteristics of the product itself are tested under given environmental conditions.
The refrigeration system of the test box adopts a cascade refrigeration system composed of imported compressors. The refrigeration system has the advantages of reasonable matching, high reliability, convenient use and maintenance, etc., and the refrigerant is adiabatically expanded by the shut-off valve, and the refrigerant is used. The temperature 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. The design of the refrigeration system applies energy regulation technology. An effective treatment method can ensure the energy consumption and cooling capacity of the refrigeration system can be effectively performed under the normal operation of the refrigeration unit. Adjustments reduce the operating costs of the refrigeration system to a more economical state.
