What is a "high and low temperature damp and heat test box"

The high and low temperature damp and heat box is also called "high and low temperature damp and heat test box". The high and low temperature damp and heat box is a test device that can simulate the temperature and humidity range and is suitable for high and low temperature reliability tests of industrial products. For electronic and electrical, automobile and motorcycle, aerospace, marine weapons, universities, scientific research units and other related products, components and materials are tested under the condition of periodic changes in high and low temperatures (alternating). Low temperature range: 0 to -80, high temperature range: RT 10-150 degrees, humidity and heat range: 30% to 98% RH

In order to ensure the cooling speed and minimum temperature requirements of the high and low temperature humid heat box, 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, and convenient use and maintenance. The refrigerant through the stop valve adiabatic expansion work, the refrigerant temperature is reduced. Finally, the refrigerant isothermally absorbs heat from the higher temperature object through the evaporator, thereby reducing the temperature of the object to be cooled. Repeat this cycle to achieve cooling. The design of the refrigeration system uses energy regulation technology. An effective treatment method can ensure that the energy consumption and cooling capacity of the refrigeration system are effectively performed under the normal operation of the refrigeration unit. The adjustment reduces the operating cost of the refrigeration system to a more economical state.
