Abstract:

An assembly that harnesses solar power for diverse applications. The principal application utilizes three closed loop elements for operating an air conditioning system. The first loop is a brine-carrying conduit, said brine being heated in a solar collector. The heat of said brine is exchanged, in a boiler means, to a refrigerant fluid carried by a second loop element. The vaporized refrigerant fluid drives a first double acting air cylinder which in turn drives a second air cylinder that can be single acting for some pumping application and which is double acting in the air conditioning application. In such air conditioning application, the second air cylinder serves as the refrigerant fluid compressor means for the assembly. A countershaft member which carries the fans for the evaporator and condenser coils of the air conditioning system is rotated by a linkage apparatus that converts axial oscillation of the output shaft of the first air cylinder member into unidirectional rotation of such countershaft member, and a pump that circulates the refrigerant fluid through the second loop is also driven by said countershaft member. A third loop element condenses the spent refrigerant fluid--in a heat exchanger means--for subsequent re-expansion in the first double-acting air cylinder member--by transferring the heat of said spent fluid to cool water circulating through said third loop, a portion of said third loop being underground to lower the temperature of such water.
