Abstract: A heat pump including at least two refrigerant injection flow paths into a scroll compressor and a main circuit. The main circuit includes a scroll compressor, a condenser, an expansion valve, a phase separator, and an evaporator for evaporating refrigerant. The scroll compressor is provided with a first refrigerant injection port between an inlet of the scroll compressor and an outlet of the scroll compressor, and a second refrigerant injection port between the inlet and the first refrigerant injection port. A first refrigerant injection flow path is bypassed from the phase separator. An internal heat exchanger is installed between the phase separator and the evaporator. A second refrigerant injection flow path is bypassed between the phase separator and the internal heat exchanger. The second refrigerant injection flow path is passed through the internal heat exchanger.

Abstract: A heat pump according to the present invention comprises a plurality of the compression chambers, and compresses refrigerant with multistage, and injects vapor refrigerant into the space between the plurality of the compression chambers by using the first refrigerant injection flow path and the second refrigerant injection flow path. Performance and efficiency of the heat pump can be improved compared with non-injection, as flow rate of the refrigerant circulating the indoor heat exchanger is increased. Thus heating performance can be improved also in the extremely cold environmental condition such as the cold area by increasing the injection flow rate. Also, because the heat pump according to the present invention comprises the first refrigerant injection flow path and the second refrigerant injection flow path, refrigerant is injected twice. Thus, as the injection flow rate of the refrigerant is increased, heating capacity can be improved. Also, the difference between the suction pressure and the discharge pressure of the rotary compressor may be decreased, and thus the reliability and the performance of the rotary compressor can be improved.
