Solar chimneys integrated with sea water desalination

A new solar chimney power system with integration of sea water desalination has been introduced for the production of electricity and fresh water in this paper. Two mathematical models have been developed individually for a one-dimensional flow in solo solar chimney power system and this system. Through theoretical analysis, it has been demonstrated the integrated system can significantly improve the solar energy utilization efficiency as well as the land resources utilization efficiency, at the same time, the economic, social and ecological benefits can also be significant. The integrated system suits to be developed in Northwest China very much. ► A new solar chimney integrated with seawater desalination has been introduced. ► Two steady-state models have been developed individually. ► The performance and benefits of the integrated system have been investigated. ► The integrated system suits to be developed in Northwest China very much.
