Refrigeration system: The refrigeration system is one of the key parts of the constant temperature and humidity machine. In general, the refrigeration methods are mechanical refrigeration and auxiliary liquid nitrogen refrigeration. Mechanical refrigeration uses vapor compression refrigeration, which is mainly composed of compressor, condenser, throttle mechanism and evaporator. If the temperature of our test is to reach -55 ℃, single-stage refrigeration is difficult to meet the requirements, so the cooling method of the constant temperature and humidity machine generally uses cascade refrigeration. The refrigeration system of the constant temperature and humidity machine is composed of two parts, called high temperature part and low temperature part, each part is a relatively independent refrigeration system. The evaporation of the refrigerant in the high temperature part absorbs the heat from the refrigerant in the low temperature part and vaporizes; the evaporation of the refrigerant in the low temperature part absorbs heat from the object to be cooled (air in the test machine) to obtain the cooling capacity. The high temperature part and the low temperature part are connected by an evaporative condenser, which is both the condenser of the high temperature part and the condenser of the low temperature part.
