Experimental Study on the Novel Solar Adsorption Refrigeration Cooling Tube

Using solar light as energy and compound adsorbent/water as working pair, the novel solar cooling tube was made and experimental studied in this paper. The experimental results show that, when the solar radiation was about 19.6-21.9 MJ-d^-1m^-2 at the daytime, the temperature of adsorbent bed could reached to 220degC, the condensation temperature was about 45degC. In the nighttime, the evaporator temperature was about 15degC, the novel solar cooling tube could supply cooling mass about 300-390 kj and the COP is about 0.23-0.25 and the refrigeration power was varied from 15W to 2W.
