The high and low temperature impact test chamber is correctly operated according to the operating procedures, and its structure should be understood. The high and low temperature damp heat test chamber is composed of a box body, a wind circulation system, a refrigeration system, a heating system and a humidity control system, and the air circulation system is generally adopted. The structure of the air supply direction can be adjusted; the humidification system has two types of boiler humidification and surface evaporation; and the cooling and dehumidification system adopts an air conditioning working condition refrigeration structure.
The high and low temperature impact test chamber heating system adopts electric fin heating and electric furnace wire to directly heat the two structures; the temperature and humidity test method adopts the dry and wet ball test method, and also the humidity sensor direct measurement method; the control and display operation interface is separated by temperature and humidity independently. And the combination of temperature and humidity controller.
High and low temperature impact test chambers will have other phenomena in use, so specific phenomena, specific analysis and elimination, high and low temperature damp heat test chambers should be regularly maintained, and the condenser of the refrigeration system should be cleaned regularly. These work are essential for refueling according to the instructions, regular maintenance inspection of the electrical control system, etc.
