Abstract:

An energy efficient air conditioning system preferably includes a compressor, a reaction turbine, an electrical generator, an expansion device, an evaporator coil, an evaporator fan and a refrigerant gas. A condenser coil and fan are replaced with the reaction turbine. Hot high pressurized gas is piped into the reaction turbine from the compressor, which causes a drive shaft of the reaction turbine to spin the electrical generator. High pressurized liquid exits the reaction turbine into the expansion device as a high pressure liquid. A low pressure liquid exists at an output of the expansion device and enters the evaporator coil. The low pressure liquid boils, absorbing heat in the evaporator. The evaporator fan blows warm air from a confined space over the evaporator coil to provide a flow of cold air to the confined space. The low pressure gas then enters the compressor to start a new cycle.
