Abstract: A closed loop system utilizing a solar refrigerant turbocharger and pump in conjunction with a solar collector to operate a heating and cooling system for a building by utilization of a renewable energy source. The liquid pump within the solar turbocharger is used to boost the refrigerant pressures into the solar collector, the refrigerant absorbs heat inside the solar collector and changes phase from a liquid to a vapor. The vapor is expanded across the turbine causing the turbine to spin. The ability of the refrigerant to change phase or flash from a liquid to a vapor is due to the solar energy that is transferred from evacuated tubes into the solar collector manifold and into the refrigerant. The gas is routed to the solar turbo pump turbine to drive the compressor and liquid pump. The resulting fluid gas leaving the turbine is routed to the condenser for normal operation.
