Solar chimney power generation — An experimental research on comprehensive sea water distillation system

This paper has been set up for a small-scale experimental device for solar chimney power generation - sea water desalinization of synthetic system. Through contact temperature measuring devices, we study the temperature rise of internal system, of the glass cover, of heat collector, air temperature rise, variation of water production hourly and changes in the relationship. The results show that water storage can maintain the basic work day and night. The sea water thickness is 80 mm of storage water and environmental temperature difference is between 2.5square and 20square. Air temperature at the entrance of chimney has a greater improvement comparing to the one at the entrance of heat collector. At 13:00, the greatest improvement of air temperature reaches around 11square and the maximal difference between air temperature and environmental one is up to about 15square. The main output collection of fresh water areas is in the absence of irradiance time. At 20:00 water production arrives at the maximum, 182 g/(m² middot h), which reaches the minimum in the strong radiance time, so the efficiency of solar energy in use of the device is above 21.13% Multi-targeted products of synthetic system comparing to the solar chimney power generation system, the efficiency of solar energy in use enhances substantially and to highlight the economic performance at the same time.
