High and low temperature humidity chamber has the advantages of overall structure, beautiful surface, multi-wing fan strong circulation, not easy to generate steam frosting and so on. It can be used for the design of air circulation in and out, long-term operation is reliable, and environmental protection refrigerant refrigeration, and has recording printer and remote temperature control system and other optional accessories. It can effectively control the change of room temperature and realize high and low temperature alternating humidity and heat test. In addition, the practicality of color touch screen human-machine interface is more prominent.

The function analysis of heating system in high and low temperature humidity chamber: The heating system is the key link of the temperature control device. When the controller receives the temperature rise instruction, it will output about 3-12V DC electricity to the solid-state relay; the circulating fan will bring the heat into the chamber, and the controller will adjust the temperature through on-off on the solid-state relay. The device generates heat and refrigeration cycle cooling through the solid-state relay to achieve temperature stabilization. It can be seen that the heating system plays an important role in the humidity and heat test chamber.

The key steps of high and low temperature humidity chamber are important parameters to identify the performance of the equipment. The test chamber consists of compressor, condenser, throttling device and evaporator. Compressor is the core of refrigeration system. It inhales low temperature and low pressure gas, and releases it as high temperature and high pressure gas, and the heat will be dissipated by the fan. Then the low pressure liquid enters the evaporator through throttling device. The refrigerant absorbs the heat in the evaporator to achieve the purpose of temperature reduction. The dehumidification is also achieved by the system: When the temperature is low, the moist items in the equipment chamber will be dehumidified by continuous circulation.

Using high and low temperature humidity chamber box for humidity and heat test can verify the physical properties and reliability of the specimens at the same time. The common humidity and heat test methods are constant humidity and heat test and alternating humidity and heat test. The constant humidity and heat test adopts the way of making the specimen moisture absorption through water vapor without temperature and humidity change, which can quickly simulate the conditions used in actual environment. The alternating humidity and heat test is the humidity and heat test with high and low temperature cycle period in the high humidity by alternately condensing and drying water vapor. This method can verify the physical properties and reliability of the specimen at the same time, and is suitable for the humidity and heat test of all kinds of products.
