Problems in constant temperature and humidity test chamber refrigerator
The constant temperature and humidity test chamber adjusts the temperature and humidity in the tank to a given value in a certain way, and conducts experiments under the conditions, in the experimental reaction requirements. That is, a test chamber capable of simultaneously applying temperature and humidity stress. In short, it refers to a test chamber where both temperature and humidity are controlled within a specified range. Constant temperature and humidity test chamber refrigeration problem:
A. There is no problem with the electrical system. Continue to check the refrigeration system. Firstly, the exhaust and suction pressures of the low-temperature (R23) compressors of the two groups of refrigeration units are lower than the normal values, and the suction pressure is evacuated, indicating that the refrigerant capacity of the main refrigeration unit is insufficient. Touching the exhaust and suction lines of the R23 compressor of the main unit by hand, it is found that the temperature of the exhaust line is not high, and the temperature of the suction line is not low (not frosted), which also indicates the R23 of the host group. Lack of refrigerant.
B. Since the temperature is not maintained, observe whether the refrigeration compressor can be started during the operation of the test box, and the compressor can be started during the operation of the environmental test equipment, indicating that the electrical circuit from the main power supply to each compressor is normal, and the electrical appliance There is no problem with the system.
Through the above explanations, I hope that we can help our customers to encounter problems when using the constant temperature and humidity test chamber.
