A system 300 has: 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; an expansion device 28; and a second heat exchanger 302. Conduits and valves are positioned to provide alternative operation in: a cooling mode and a heating mode. In the cooling mode, a needle of the ejector 32 is closed. In the heating mode refrigerant passes sequentially from a first section of the second heat exchanger to a second section. In the cooling mode refrigerant passes in parallel through the first section and the second section.
