Humid heat tester

The designed life of Solar cell module is about 20-30 years. But the reliability experiment is to verify the design by simulating the land-based photovoltaic module (crystalline Silicon, Amorphous Silicon , thin-film, concentrator-type) so that modules can long-term work in general high temperature and high humility for more than 20 years.
Solar cell is in need of regulatory requirements: Damp Heat test to determine the influence of sub-zero temperature after Solar Cell exposion to high temperature and high humility, and to determine the fatigue and thermal failure resulting from temperature repeated change, and to determine the ability to resist long-term moisture penetration. The design and ability of testing equipment has to meet the relevant requirements (IEC61215、IEC61646、 IEC62108、UL1703、IEEE 1513、IEC61730 etc)

1.The controller operation uses the fuzzy algorithm, the latest technology control and proper adjustment of refrigeration to make the best results; 7 "TFT true color LCD touch screen is larger than the other screens.
2.the controller interface of humanization design has more convenient operation and more reliable operation.
3.the refrigeration control system adopts cooling demand algorithm to reasonably and effectively use cooling capacity and effectively reduce the mutual consumption of heat and cold so as to achieve control stability and energy saving
4.The coupling PID adopted by the temperature and humidity control can effectively prevent the sudden runaway of the controlled humidity value, which not only makes constant temperature and humidity but also achieves well the function of alternating temperature and humidity .
5.the refrigeration system adopts imported compressor which has the lower noise and better performance.
6. The sampling calculation for a second can ensure the real-time curve sampling and historical data storage for 110 days.
The sampling rate can be arbitrarily set from 3 seconds to an hour.
7. Extra long constant time of 99999 hours 
8. the program segment setting time of 540 hours and 59 minutes
9. There is the USB interface to connect computer and corporate LAN.
