すぐに冷たくならないようにされている。 Next, the operation will be explained. In winter, the first and second valves 5 and 6 are opened, and the third valve 7 is closed. Therefore, the clean water in the pipe 13 pumped up by the pump 12 passes through the heat exchanger 4. While passing through this heat exchanger 4, the fan 3
The water supply is warmed by the warm air from the second
The water is stored in the water storage tank 9 through the valve 6 and the water inlet pipe 10. On the other hand, the water level in the water storage tank 9 is controlled to be at a high level A during the day and at a low level B at night, as will be explained below. That is, the tap water is not used much at night, and the tap water in the water storage tank 9 is cooled by the low surrounding temperature, and this cooled tap water must be used in the morning. Therefore, the control device 1
6, the water level in the water storage tank 9 is set to low level B at night when the amount of water used is low.
The operation of the pump 12 is controlled so that Next, when activities in the building begin, a timer built into the control device 16 controls the operation of the pump 12 so that the water level in the water storage tank 9 reaches the high level A, and the heat exchanger 4 is activated. The warmed water passing through is pumped up to a water storage tank 9, so that the warmed water can be used from the morning. In addition, this warmed water is stored in the water storage tank 9, which is thermally insulated.
It is made so that it does not get cold too quickly.
次に夏季においては、第１、第２のバルブ５，
６が閉じられ、第３のバルブ７が開放される。こ

朝から冷たい上水を使用することができる。 Next, in the summer, the first and second valves 5,
6 is closed and the third valve 7 is opened. Therefore, the cold water in the pipe 13 is directly pumped into the water storage tank 9 by the pump 12. Also, in this summer, by setting the water level in the water storage tank 9 to the low level B at night as described above and to the high level A in the morning, the tap water in the water storage tank 9 can be warmed by the ambient temperature. can be prevented,
You can use cold tap water from the morning.
