Heat pump with ejector
Abstract
A system (20; 300; 500) comprises: a compressor (22) having a suction port (40) and a discharge port (42); an ejector (32) having a motive flow inlet (50), a suction flow inlet (52), and an outlet (54); a separator (34) having an inlet (72), a vapor outlet (74), and a liquid outlet (76); a first heat exchanger (24); at least one expansion device (28, 30; 520); a second heat exchanger (26); and a plurality of conduits and a plurality of valves (100, 120, 130, 140, 144, 148, 150; 100, 140, 144, 148, 150, 320, 340; 100, 120, 530). The conduits and valves are positioned to provide alternative operation in: a cooling mode; a first heating mode wherein the ejector has a motive flow and a suction flow and where utilizing a first expansion device (30; 520) of the at least one expansion device; and a second heating mode utilizing the first expansion device and wherein the ejector has a suction flow and essentially no motive flow.
