Features
Cooling is an important part of the high and low temperature test chamber, and it is an important parameter
to determine the performance of a constant temperature and humidity machine. It consists of four
components: compressor, condenser, throttling device, and evaporator. The compressor is the heart of the
refrigeration system. It inhales low-temperature and low-pressure gases, turns into high-temperature and
high-pressure gases, and releases heat through condensation into liquids. The heat is taken away by fans.
Therefore, the temperature below the constant temperature and humidity is caused by hot air, and then it is
throttled to low-pressure liquids. Secondly, through the evaporator, it becomes the 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 absorb heat to achieve the purpose of cooling, and completes the
process of cooling the constant temperature and humidity.
