Abstract

A heat pump-type cooling/heating system of the present invention includes a refrigeration circuit, a hot water generating means and an indoor heat exchanger assisting means. In the refrigeration circuit, a compressor, a four-way valve, an indoor heat exchanger, a cooling expansion valve, a heating expansion valve, an outdoor heat exchanger and the four-way valve are connected in a sequence by a refrigerant conduit. The four-way valve and the compressor are connected by a suction conduit. The hot water generating means includes a bypass conduit and a double tube-type heat exchanger. The double tube-type heat exchanger has a condensation tube which is provided in a storage reservoir, and a heat medium heating conduit inserted into the condensation tube. The indoor heat exchanger assisting means includes an auxiliary heat exchanger which is located beside the indoor heat exchanger and connected to the heat medium heating conduit by a supply conduit provided and by a return conduit.
