An air aspirated hybrid heat pump and heat engine system (20) for selectively heating and cooling a space (22) having an flow path (24) including a compressor (76), a heat exchanger (32), an expander (78), and a generator (68). A combustion chamber (62) is in the flow path (24) for combusting a fuel in the air during a high heating mode. The heat exchanger (32) dissipates the heat from the air, and the expander (78) depressurizes the air while powering the generator (68). Also included is a positive displacement rotating vane-type device (36) having a stator housing (38) extending between longitudinal ends (40). A compression chamber inlet (52) and an expansion chamber outlet (58) are located on opposite longitudinal ends (40) of the stator housing (38) to be in simultaneous communication with the same chamber (48, 50)). A fluid enters the device through the compression chamber inlet (52) and pushes fluid out of the expansion chamber outlet (58). |
