System introduction：

The principle of rapid temperature change test chamber for simulating environment: By providing a series devices of cascade refrigerating system,which are compressor,condenser,evaporator - and closure device, it can make the cold source and heat source to cool down and heat up rapidly to get a certain temperature in the environment.

Test of rapid temperature change test chamber：Find out the respective maximum and minimum operating temperatures in the parts as well as the maximum and minimum storage temperatures, which will lead it closing to the ultimate temperature of designing. By screening the products under this kind of severe environment repeatedly, the faults that are caused by the potential design defects, manufacture defects and components faults can be found.

Test purpose of rapid temperature change test chamber：To find and eliminate the early failure of the product, which will make it enter to the stage of random failure stage during the leaving factory period, it will ensure the product quality and deliver it to the customer with inherent reliability.

This design can save more than 30% electricity compare with traditional design.
