A heat pump system is equipped with a compressor (10), a condenser (12) and an evaporator (14) and has a construction in which at least either one of the condenser and the evaporator includes a plurality of heat exchange chambers (20a-20d, 24a-24d), at least either one of the delivery side and the suction side of the compressor includes a plurality of ports (26a-26d, 28a-28d) that are on different pressure levels, and the plurality of heat exchange chambers and the plurality of ports are connected to each other. Furthermore, another mode of the heat pump system in accordance with the present invention includes a high-temperature cycle which is equipped with a high-temperature compressor and a condenser, a low-temperature cycle which is equipped with a low-temperature compressor and an evaporator and a cascading heat exchanger. |
