Claim 0:
1. A heat pump, comprising:
a refrigerant loop, wherein the refrigerant loop comprises:
a compressor;
a first condenser downstream of the compressor and coupled to an outlet port of the compressor;
a vapor generator downstream of the first condenser;
a branching point positioned between the first condenser and the vapor generator, wherein the branching point diverts a portion of a first heat exchange fluid circulating through the refrigerant loop to a first inlet of the vapor generator;
a first expansion valve positioned between the branching point and the vapor generator, wherein a first outlet of the vapor generator is coupled to a mid-pressure inlet port of the compressor;
a second expansion valve positioned downstream of the vapor generator and coupled to a second outlet of the vapor generator, wherein a second inlet of the vapor generator is coupled to the first condenser; and
a first evaporator downstream of the second expansion valve and coupled to the second expansion valve, wherein the first evaporator is upstream of the compressor and is coupled to a low-pressure inlet port of the compressor.
