【 Compliant with standards 】 ◇ GB/T19394 ◇ GB/T9535 ◇ GB/T6492 ◇ GB/T6494 ◇ GB/T6497 ◇ SJ/T2196 ◇ IEC61345 ◇ IEC61646 At the same time, it complies with the temperature and humidity standards of IEC61215-2005, and can perform various high and low temperature humidity and humidity alternating environment tests. The wet freezing test chamber for photovoltaic modules is a testing equipment mainly used in the photovoltaic and solar energy industries to test the parameters and performance of a series of photovoltaic modules, including monocrystalline silicon modules, ground crystalline silicon photovoltaic modules, ground thin-film photovoltaic modules, etc., under high temperature, low temperature, alternating humidity or constant temperature environment changes; The parameters and performance of the constant humidity and heat test after temperature environment changes Suitable for schools, factories, research institutes, and other institutions. The box is processed and formed by CNC machine tools, with a beautiful and elegant shape, and adopts non reactive handles for easy operation. The inner liner of the box is made of stainless steel, and the outer liner of the box is made of galvanized steel plate, treated with phosphating electrostatic spraying, which increases the appearance texture and cleanliness. The water replenishment tank is located at the bottom right of the control box and has automatic water shortage protection, making it more convenient for operators to replenish water sources. The large observation window is equipped with lighting to keep the inside of the box bright, and the micro tempered glass inside the heating element is used to clearly observe the condition inside the box at any time. Separating the humidification system pipeline from the control circuit board can prevent malfunctions caused by water leakage in the humidification pipeline and improve reliability. The waterway system pipeline circuit system adopts a door type opening, which is convenient for maintenance and inspection. The insulation of the box is made of ultra-fine glass fiber insulation cotton, which can avoid unnecessary energy loss. A 100mm test hole is provided on the left side of the box, which can be used for external testing power or signal lines. Programmable controller The humidity control instrument adopts a fully large LCD screen, with simple screen operation and easy program editing. And the app can be upgraded. The controller operation interface is equipped with Chinese and English screens for selection, and the real-time operation curve chart can be displayed on the screen. It has a capacity of 100 sets of programs, 1000 segments, and 999 loop steps, with a set maximum value of 99 hours and 59 minutes per time segment. After inputting the data and experimental conditions, the controller has a locking function to avoid manual touch and shutdown. Equipped with RS-232 or RS-485 communication interface, it can be programmed on a computer to monitor the testing process and perform functions such as automatic power on/off. It has the function of automatic calculation, which can immediately correct the temperature and humidity change conditions, making temperature control more accurate and stable. Freezing and air circulation system The refrigeration unit adopts French original 'Taikang' or German blog compressor. The refrigeration system adopts a unit or binary low-temperature refrigeration system design. Adopting a multi wing air circulation system to avoid any dead corners can ensure even temperature distribution within the testing area. Wind path circulation design for air outlet and return, windThe pressure and wind speed meet the testing standards, and can make the temperature return time faster when the door is opened. Heating, cooling, and system independence can improve efficiency, reduce testing costs, extend lifespan, and decrease failure rates. [Specifications and Technical Parameters]
