Experimental Study on Modularization for Solar Semiconductor Air-Conditioning Refrigeration

The solar pyroelectricity module refrigeration experiment system was built taking water as heat exchange intermediary. The system deployed dual energy memory device to store the energy of day and night temperature difference, so it would be able to continue working for the system if sunshine was insufficient. Refrigeration was modularized in order to suit for space refrigeration with great power changing, and to realize high-power in or out at starting refrigeration and maintaining different temperature periods. Semiconductor pyroelectricity components were mainly used in refrigeration module, red copper as heat exchange material for its fine heat conduction function at the cold or hot end, water was used as cooling liquid and heat circulation liquid. Heat-exchanging system adopted integration heat-exchange system. The experimental analysis and simulation were carried out on the property of refrigeration module, the results met the design basically.
