How to judge the performance of the constant temperature and humidity machine.

Cooling is an important part of a constant temperature and humidity machine. It is important to determine the performance of a constant temperature and humidity machine. The high and low temperature test chamber is composed of compressor, condenser, throttling device and evaporator. The compressor is for refrigeration. The heart of the system, it sucks in low-temperature and low-pressure gas, turns into high-temperature and high-pressure gas, releases heat by condensing into a liquid, and takes away the heat by a fan. Therefore, under the constant temperature and humidity machine is the cause of hot air, and then throttling to low pressure liquid, and then through evaporation The device becomes a low temperature and low pressure gas and finally returns to the compressor.

The refrigerant absorbs heat in the evaporator to complete the gasification process and absorbs heat to achieve the purpose of refrigeration and complete the cooling process of a constant temperature and humidity machine.
