Economic Analysis and Experimental Study of Solar Cooling Tube Combined with Building
The solar cooling tube and the economic analysis were studied for supplying cooling and heating capacity on the building. The following conclusion could be drown: The refrigerating output of a single solar cooling tube was about 2 W to 13 W varying with the time. And the unit made up by 20 solar cooling tubes could supply about 3.96 MJ cooling capacity and 10.73 MJ heating capacity. The investment of the solar cooling tube combined with average 20m2 building is about 46000 RMB at present price and the fixed number of years necessary for redemption is about 7.5 years.
