設けられている。Furthermore, a water pipe 9 on the load side is connected to the storage 1hWI2, and this water pipe 9 is connected to a circulation pump 10 on the load side.
A plurality of faucets 11 for supplying hot water are also provided.
次に動作について説明する。この給湯用ヒートポンプ装
置では、負荷側の循環ポンプ１０は常時オンしている。Next, the operation will be explained. In this heat pump device for hot water supply, the circulation pump 10 on the load side is always on.
蛇口１１より温水が使用されると、貯湯槽２への還水が
減じ、貯湯槽２内の水位は満水位レベルＡより下がる。When hot water is used from the faucet 11, the amount of water returned to the hot water tank 2 is reduced, and the water level in the hot water tank 2 falls below the full water level A.
この水位の低下は水位レベルスイッチ１４により検知さ
れ、制御装置１３により電磁弁６が開き、加熱用ヒート
ポンプ１および循環ポンプ４がオンする。This drop in water level is detected by the water level switch 14, and the control device 13 opens the solenoid valve 6, turning on the heating heat pump 1 and the circulation pump 4.
