により水循環回路が構成され、３ 、。As shown in the figure, the hot water system of this embodiment 118- is composed of a hot water tank 2 insulated with a heat insulating material 1 used as a heat insulator, and an air source heat pump heating device 3. The heat pump heating device 3 includes a compressor 4, an air heat source evaporator 6,
It is constructed by connecting a heat source fan 6 and an expansion mechanism 7 to a refrigerant circulation circuit, respectively, and a water heating heat exchanger 8 and a refrigerant connecting pipe 9 installed in the upper part of the hot water storage tank 2 in a heat-insulating manner with a heat insulating material 1. A heat pump heating circuit is constructed by connecting them at 10°. Water is supplied from a circulation water supply port 11 provided below the hot water storage tank 2, and includes a circulation pump 12, a water pipe line 13, a water heating heat exchanger 8, and a water pipe line 14 connected to the upper part of the hot water storage tank 2.
A water circulation circuit is constructed by 3.

出湯管である。Bay 7 Water supplied from below the hot water storage tank 2 is heated by a water heating heat exchanger 8 provided in the circulation path and recirculated to the hot water storage tank 2 from above. Here, the circulation pump 12, water pipes 13, 1
4 are each covered with a heat insulating material 1 that covers the hot water storage tank 2 to keep them warm. 16 is an auxiliary heating device such as a late-night electric heater, 16
17 is a pressure reducing check valve, 18 is a safety valve, and 19 is a hot water outlet pipe.
以上のように本実施例は水加熱熱交換器８、循環ポンプ

るのを解消する事ができる。As described above, in this embodiment, the water heating heat exchanger 8, the circulation pump 12, and the water pipes 13 and 14 are each insulated with the heat insulating material 1 along with the hot water storage tank 2, which causes the problem of freezing during water circulation. It is possible to eliminate the

ので、水管路１３１１４％領環ポンプ１２の凍結対策は
必要不可欠である。In particular, in order to configure the water heating heat exchanger 8 as a counter-flow type and to control the hot water temperature at the outlet to a constant level, a hot water temperature regulating valve (not shown) is installed between the water pipe line 14 and the outlet of the water heating heat exchanger 8. If the hot water storage tank 2 is installed or the circulation amount of the circulation pump 12 is controlled,
Since it is necessary to configure the water heating heat exchanger 8 and the water heating heat exchanger 8 independently, measures against freezing of the water pipe line 13114% area ring pump 12 are essential.
本参肴によらない別の構成としてヒートポンプ加熱装置
ａ内に水加熱熱交換器８を配設する事も考えられるが、
この場合は水管路１３．１４を低外気雰囲気中を長い距

。As another configuration other than this one, it is conceivable to arrange the water heating heat exchanger 8 in the heat pump heating device a.
In this case, the water pipes 13, 14 must be disposed over a long distance in a low-temperature outside atmosphere, and the risk of freezing becomes extremely high. In addition, as a countermeasure against freezing, a method of circulating antifreeze as a heat medium in the water heating heat exchanger 8 and arranging a second heating heat exchanger in the hot water storage tank 2 can be considered, but heat exchange is performed in two stages. This makes it difficult to maintain a high water temperature and the equipment is complicated.
これに対し本脚実施例は冷媒接続管９，１０で接続する
為に凍結の問題は全く生ずる事なく、簡略な構成で高い
湯温′を確保し乍ら、凍結問題の解決を図れる。On the other hand, in the present embodiment, since the refrigerant connecting pipes 9 and 10 are used for connection, the freezing problem does not occur at all, and the freezing problem can be solved while ensuring a high water temperature with a simple structure.

とができる。In addition, if the hot water storage tank 2 is a push-up hot water supply system in which the water supply port 16 is arranged at the bottom and the hot water supply pipe 19 is arranged at the top as shown in the figure, the circulation pump 12 and the water heating heat exchanger 8 are arranged at the top of the hot water storage tank 2. By installing and configuring this, it is possible to reliably obtain the hot water sampling effect of the circulation pump 12 and the water heating heat exchanger 8 even when the remaining hot water in the hot water storage tank 2 becomes low.
