The operation of the constant humidity and constant humidity machine system is through three interconnected systems: refrigerant circulation system, air circulation system, electrical appliance automatic control system; refrigerant circulation system, the liquid refrigerant in the evaporator absorbs the heat of the air (the air is cooled And dehumidification) and start to evaporate, and finally a certain temperature difference is formed between the refrigerant and the air, and the liquid refrigerant is completely evaporated to a gaseous state, and then is sucked and compressed by the compressor (pressure and temperature increase), the gaseous refrigerant passes through the condenser (Air-cooled / water-cooled) Absorb heat and condense into liquid. After being throttled by an expansion valve (or capillary), it turns into a low-temperature and low-pressure refrigerant and enters the evaporator to complete the refrigerant circulation process. Constant temperature and humidity controller Constant temperature and humidity machine (constant temperature and humidity test box | programmable constant temperature and humidity test machine | high and low temperature alternating humidity and heat test box) mainly provides constant humidity and heat for the testing of electronic components, industrial materials and finished products in the development, production and inspection , Complex high and low temperature alternating test environment and test conditions, suitable for various industries such as electronic appliances, communications, chemical, hardware, rubber, toys, etc. Executive Standard GB / T 10592-1989 high and low temperature test chamber technical conditions GB / T 10592-2008 high and low temperature test chamber technical conditions GB / T 2423.4-1993 Basic environmental test procedures for electrical and electronic products Test Db: Alternating damp heat test method GB / T 2423.4-2008 Environmental testing for electrical and electronic products. Part 2: Test method test Db alternating humid heat (12h + 12h cycle), etc. ★ Perfect shape design: arc shape and surface spraying treatment, high-quality appearance, and flat non-reaction handle, easy to operate, safe and reliable. ★ Large observation window has a wide and bright field of view: It adopts three-layer vacuum-coated windows and Philips energy-saving fluorescent lamps, without the need for wipers to remove fog, to maintain a clear observation effect, and to observe the status of the sample at any time. ★ Water and electricity separation to ensure safety: the humidification system pipeline is separated from the power supply, controller, and circuit board, which can avoid the leakage of the pipeline and affect the circuit, and improve safety. ★ Refrigeration and control system is advanced and reliable: original imported European and American hermetic compressors, imported environmentally friendly refrigerants, world-renowned brand refrigeration devices, original imported LCD touch screen controller, friendly interface, simple operation and easy to learn Inkjet Machine Accessories
