PURPOSE:To prevent the breakage of a boundary layer between the hot-water and water by a method wherein the inlet port as well as the outlet port of water stream are provided at substantially same height near the bottom of a hot-water reserving tank. CONSTITUTION:A heat pump cycle is constituted by a compressor 3, a heating heat exchanger 4, a choke valve 5, an evaporator 6 and an accumulator 7 while the water stream outlet port 11' and the water stream inlet port 13'', equipped with a control device 21 such as a baffle plate or the like, are provided at substantially same height near the bottom of the hot-water reserving tank 1, and both of them are connected to the heating heat exchanger 4 through a sending pipe 10', equipped with a pump 9, and a returning pipe 12'. The water stream outlet port 11' and the water stream inlet port 13'' are opposed mutually in case of (a) shown by the diagram, or the inlet port 13'' is provided with a rectifying plate 22 in case of (b) shown by the diagram while it is provided with an internally extended pipe 23 in case of (c) as shown by the diagram. According to these constitutions, short-circuit current will never be caused. |
