How to deal with abnormal situation of constant temperature and humidity test chamber

The structure shall be understood for constant temperature and humidity test chamber in accordance with the humidity during operation and use by personnel. The constant temperature and humidity test chamber is composed of air circulation system, refrigeration system, heating system and humidity control system. These systems are directly related to the price of test chamberes. In the general air circulation system, the air supply direction is adjustable, and the boiler humidification and humidification system and surface evaporation are used.

If the temperature of constant temperature and humidity test chamber fails to reach the test temperature, the electrical system can be checked and the fault can be eliminated gradually. If the temperature rises slowly, it is necessary to open the regulating baffle for the air circulation system, whether the air circulation pair and motor operate normally. When the temperature is over adjusted. Then set PID parameter setting. If the temperature rises, over temperature protection, then, the controller fails, replace the controller.

The low temperature can not reach the test index. Observe the temperature change. The temperature drops slowly. The temperature rises when the constant temperature and humidity test chamber or temperature reaches a certain value. Before the test, check whether the temperature is dry. In the workshop before the test, the workshop keeps the dry sample in the recording room for testing, and places too many test samples in the studio, so that the wind can not be completely round in the studio. For the above reasons To solve the problem, we should consider whether it is a fault in the refrigeration system. If so, please ask the professional personnel to repair.

constant temperature and humidity test chamber In the wet and hot test, the actual humidity will reach 100% or the actual humidity and humidity difference. The value is much lower. The former phenomenon: it may be due to the sensor of dry and wet ball gauze, which will check whether the water resource of the water tank of the wet ball sensor is short, whether the automatic water level controller of water level in the water tank is under normal control, check whether the water level controller of the water supply system and the water level controller are normal Whether it works normally. If everything is normal, check the electrical control system and ask professional maintenance personnel to carry out maintenance.
