The thermal shock test chamber is a device used to simulate the performance of products under special temperature changes, and its core working principle is mainly based on refrigeration and heating technology. The principle of low-temperature cooling in the cold and hot shock test chamber can be summarized as follows:

1、 Composition of refrigeration system

The refrigeration system of the cold and hot shock test chamber mainly consists of an evaporator, a compressor, a condenser, and an expansion valve. These components work together to complete the refrigeration cycle process.

2、 Refrigeration cycle process

The refrigeration cycle follows the principle of the inverse Carnot cycle, consisting of two isothermal processes and two adiabatic processes. The specific process is as follows:
