| By analyzing the technical features of solar hot air chimney generating electricity and refrigeration system,a solar chimney refrigeration system combining with them to provide cooling water without electricity was proposed.It is made up of chimney,heat collector,heat storage layer,turbine,open-type compressor,condenser,and transmission.The operation principles,structure characteristics and geometric theory of this refrigeration system were formulated and analyzed,and the calculation formulae for refrigeration performance parameters and size of chimney and heat collector were deduced preliminarily basing on rated cooling capacity.The analysis results show that this mechanism is of simple structure,easy operation and maintenance,refrigerating without electricity,no pollution and has good environmental effect.It can change the speed of the compressor to regulate cooling load according to the ambient temperature,besides,it can effectively solve the problem of cooling and power supply in tropical and desert regions. |
