　　IIIconstant temperature and humidity chamberrefrigeration system

　　The refrigeration system is one of the key components of the comprehensive test chamber. Generally speaking, the refrigeration methods are mechanical refrigeration and auxiliary liquid nitrogen refrigeration. Mechanical refrigeration adopts vapor compression refrigeration, which mainly consists of a compressor, condenser, throttling mechanism, and evaporator. If we want to achieve a low temperature of -55 ℃ in our experiment, single-stage refrigeration is difficult to meet the requirements, so the refrigeration method of the constant temperature and humidity box is generally a cascade refrigeration. The refrigeration system of a constant temperature and humidity chamber consists of two parts, namely the high temperature part and the low temperature part, each of which is a relatively independent refrigeration system. The evaporation of refrigerant in the high temperature section absorbs heat from the refrigerant in the low temperature section and vaporizes; The evaporation of the low-temperature refrigerant absorbs heat from the cooled object (air inside the test chamber) to obtain cooling capacity. The high temperature and low temperature sections are connected by an evaporative condenser, which serves as both the condenser for the high temperature section and the condenser for the low temperature section.
