The constant temperature and humidity test chamber is operated through three interconnected systems. The operating systems are: refrigerant circulation system, air circulation system, and electrical automatic control system. Then the following three operating systems will be explained by the constant temperature and humidity box manufacturer Beijing Yashilin Test Equipment Co., Ltd. The refrigeration system of constant temperature and humidity test chamber: The liquid refrigerant in the evaporator of the constant temperature and humidity test chamber absorbs the heat of the air and begins to evaporate. Eventually, a certain temperature difference is formed between the refrigerant and the air, and the liquid refrigerant is completely evaporated into a gaseous state, and then absorbed by the compressor And compressed, the gaseous refrigerant absorbs heat through the condenser and condenses into a liquid. After throttling through the expansion valve, the low-temperature and low-pressure refrigerant enters the evaporator and completes the refrigerant circulation process. The air circulation system of the constant temperature and humidity test chamber: The fan is responsible for sucking air from the return air inlet. The air passes through the evaporator, humidifier, and electric heating, and then is sent to the space required by the user through the air outlet. The air sent out is mixed with the air in the space and then returned to the air outlet. The electrical automatic control system of the constant temperature and humidity test chamber: The power supply part is divided into temperature and humidity control and fault protection parts through compressors, fans, electric humidifiers, humidifiers and other automatic power supply control parts through contactors: temperature and humidity control are controlled by temperature and humidity controllers. The temperature and humidity of the return air are compared with the temperature and humidity set by the user, and the compressor, humidifier, electric heating and other components are automatically performed to realize automatic control of constant temperature and humidity.
