The constant temperature and humidity test chamber is used as a test equipment for simulating high temperature, low temperature and constant temperature. Each test process requires extremely high stability and high data accuracy. The stability can make the test work normally. The manufacturer of the constant temperature and humidity test chamber has made a unique design in its cabinet and has planned a series of test requirements for the smooth running of the test. In order to obtain accurate test data stably for the test box, relevant debugging requirements have been made. .
In daily use, a large number of users will operate according to their instructions or in the way they plan, to better operate their test chambers to achieve the best working condition. The stability of the constant temperature and humidity test chamber is closely related to its refrigeration system. For each system structure in the cabinet and the various accessories used, it is required to match perfectly. The single-stage refrigeration cycle in the test chamber is generally based on the temperature refrigerant R404A, and the lowest temperature present in the actual tank is about -36.5 ° C, so that the lowest temperature drop is obtained by the evaporation pressure of its compressor. Up to -50 ° C. If it is necessary to reduce to the lowest temperature, it uses its cascade refrigeration cycle, which will ensure the cooling stability of its constant temperature and humidity test chamber. The refrigeration system of the test chamber is complementary to its compressor and thus interacts in one state.
In the stability treatment, the refrigeration system is related to the cooling and dehumidification effects of the constant temperature and humidity test chamber. Therefore, when each system of the test box is set and started, the different effects produced, under the interaction and reasonable operation, adopt the state of mutual cooperation to achieve the most ideal and most stable effect.
