In addition, so-called stored hot water is in the time, for example refers to utilize the given time between 8 of 10 points in afternoon of electric power in the late into the night～morning.Again, the T1～T7 shown in this figure represents the hot water temperature that each temperature sensor T1～T7 detects.
The situation (the preferential situation of hot water supply of the 1st hot water storage tank 2) that the 1st hot water storage tank 2 is preferential
At first, as shown in Figure 4, judge whether at stored hot water in the time (S1).If in the time, then under the state that heat source machine 10 stops (S2) utilizes the sensor T2 of the 2nd hot water storage tank 2b to detect the interior temperature (S3) of the 1st hot water storage tank 2 (the 2nd hot water storage tank 2b) at stored hot water.T2 switches to preferential side setting (S4) with triple valve 7 and triple valve 17 when both fixed temperature is following, start heat source machine 10 (S5), and the 1st hot water storage tank 2 is heated up.What is called switches to preferential side and sets, and is meant triple valve 7 and triple valve 17 are switched to the side that the warm water in the 1st hot water storage tank 2 is circulated.
When T1, T2 both reach fixed temperature (S7), the T7 that further judges the 2nd hot water storage tank 4 whether be lower limit set temperature oc 1 (for example about 50 ℃) (S8).In addition, the hot water temperature of the 1st hot water storage tank 2 utilizes temperature sensor T1, the T2 of the 1st hot water storage tank 2a and the 2nd hot water storage tank 2b to detect.The thermograde layer of the warm water of the 1st hot water storage tank 2 has been considered in the position of temperature sensor T1, the T2 in the downstream when the 1st hot water storage tank 2 heats up, can judge that the upstream side (the 5th hot water storage tank 2e side) at described temperature sensor T1, T2 is storing both high-temperature water of fixed temperature (for example about 90 ℃).
When the hot water temperature who judges the 2nd hot water storage tank 4 does not reach lower limit set temperature oc 1, switch to non-preferential side and set (S9).At this, what is called switches to non-preferential side and sets, and refers to triple valve 7 and triple valve 17 are switched to the side that the warm water in the 2nd hot water storage tank 4 is circulated.
When the 2nd hot water storage tank 4 heats up, be both fixed temperatures following (S11), then switch to preferential side and set (S12), turn back to S6, so that 2 intensifications of the 1st hot water storage tank if judge T2.
Keep under set hot water temperature's the state at the 1st hot water storage tank 2, the hot water temperature of the 2nd hot water storage tank 4 is warmed up to upper limit design temperature α 3 (for example about 60 ℃) and (S13), closes heat source machine 10 afterwards, switches to preferential side.
If at stored hot water outside the time, whether the T4 that then judges the 4th hot water storage tank 2d is both fixed temperatures (S15).T4 switches to preferential side and sets (S16) when both fixed temperature is following, and the 1st hot water storage tank 2 is warmed up to both fixed temperatures (S17).At this, utilize the temperature sensor T4 of the 4th hot water storage tank 2d to detect warm water, be to interrupt for the hot water that prevents the 1st hot water storage tank 2.Promptly, by the hot water supply, warm water in the 1st hot water storage tank 2 is suitably used, in bottom supply to the 1 hot water storage tank 2 of tap water flows water supply piping 5 and the 1st hot water storage tank 2a from the temperature sensor T4 downstream position, so before the high-temperature water that will use the 5th hot water storage tank 2e, make high-temperature water flow into the 5th hot water storage tank 2e and prevent that hot water from interrupting.
And,, when lower limit set temperature oc 1 is following (S18), switches to non-preferential side and set (S19) at the T7 of the 2nd hot water storage tank 4, the 2nd hot water storage tank 4 is heated up.When the 2nd hot water storage tank 4 heats up,, turn back to S17 so that the 1st hot water storage tank 2 heats up if judge that T4 at both (S20) below the fixed temperature, then switches to preferential side and sets (S21).
Then, the T7 of the 2nd hot water storage tank 4 reaches middle design temperature α 2 (for example about 55 ℃) when above (S22), if then heat source machine 10 is closed (S23) at stored hot water outside the time, sets (S24) if then switch to preferential side in the time at stored hot water.
In addition, design temperature α 2 during the T7 of the 2nd hot water storage tank 4 is set in is for accumulation of heat, so that prepare the continuous heat of bathing pool 33, and can be rapidly and do not have the hot water supplying temperature warm water of suitable continuous heat interruptedly.
The following describes the situation of establishing the 2nd hot water storage tank 4 preferential (preferential continuous heat).
At first, as shown in Figure 5, judge whether at stored hot water in the time (S1).If in the time, then under the state that heat source machine 10 stops, detecting the T7 (S2) of the 2nd hot water storage tank 4 at stored hot water, T7 is when lower limit set temperature oc 1 is following, switch to preferential side and set (S3), start heat source machine 10, heating up reaches upper limit design temperature α 3 (S4) up to T7.At this, what is called switches to preferential side and sets, and refers to triple valve 7 and triple valve 17 are switched to the side that the warm water in the 2nd hot water storage tank 4 is circulated.
And the T2 of the 1st hot water storage tank 2 is (S5) when both fixed temperature is following, switches to non-preferential side and sets (S6), and the 1st hot water storage tank 2 is heated up.What is called switches to non-preferential side and sets, and refers to triple valve 7 and triple valve 17 are switched to the side that the warm water in the 1st hot water storage tank 2 is circulated.Transfer to S5 when in addition, T7 surpasses lower limit set temperature oc 1 in S2.
