<p>A refrigerant power unit includes a closed piping loop containing refrigerant. The refrigerant is pumped to an evaporator (12) where it changes to a saturated vapor. It is directed across a generator (24) absorbing additional heat energy and changing to a super-heated hot gas. The refrigerant is directed through the nozzles in a turbine (30) and impinges upon turbine blades. As the refrigerant passes around the turbine blades, it expands and exits the turbine blades in an axial direction. The enthalpy, temperature and pressure of the refrigerant drops, reducing the refrigerant to a saturated vapor. The refrigerant then enters a condenser (36) heat exchanger dissipating heat into the surrounding medium, reducing the enthalpy of the refrigerant, changing the refrigerant into a liquid before entering the receiver tank. A pump (18) draws the liquid refrigerant from the receiver tank and pressurizes the system. The refrigerant is directed to the inlet of the evaporator, completing the cycle through the refrigerant power unit. A more detailed system includes an additional piping segment, between the receiver tank and the generator, which contains an evaporator (64), a compressor (74) and a motor (76). Another system includes a second evaporator (102) between the evaporator (100) and the generator (118). It includes a second closed piping loop containing a compressor (130) and a motor (136) between the first and third evaporators. The loop also provides the heating refrigerant for the first evaporator coil and the coolant refrigerant inside the third evaporator coil.</p> |
