In addition, this heat supply water heating mechanism of qi has the control device (not shown) that is assembled with microcomputer etc., carries out action control to heating installation operation, antifreeze operation etc. by this control device.
(heating installation run action)
Below, the run action of this heat supply water heating mechanism of qi is described.This run action is carried out by above-mentioned control device.
At first, by execution heating installation operations such as not shown remote controllers, make above-mentioned heating installation pump P1 work, and make above-mentioned heat-exchange device work.At this moment, when the heating installation operation of carrying out high temperature side terminal heating installation 3, the moving valve 300 of the heat that this high temperature side terminal heating installation 3 has self is opened.In addition, when the heating installation operation of carrying out low temperature side terminal heating installation 4, the moving valve 230 of the low temperature capability switch of above-mentioned bypass line 23 heat is opened, and be connected in carrying out in a plurality of low temperature side terminal heating installations the moving valve of heat of the moving valve head 240 of heat of low temperature side terminal heating installation of heating installation operation be opened.
Now, suppose that high temperature side terminal heating installation 3 and low temperature side terminal heating installation 4 all carry out the heating installation operation.Like this, the high-temperature-hot-water that generates in the main heat exchanger 11 of above-mentioned Heating installation heat exchanger 1 is supplied with to high temperature side terminal heating installation 3 through high temperature side terminal heating pipeline 21 from heat exchange pipe 13 of heating installation.And, the low-temperature water heating that comes out from high temperature side terminal heating installation 3 is supplied with to accumulator 20 through accumulator connecting line 26 after heating installation water return pipeline 27 flows through the heating installation latent heat heat exchange pipe 14 of the secondary heat exchanger 12 above-mentioned Heating installation heat exchanger 1 and reclaims latent heat.Moreover, a part that flows through the high-temperature-hot-water of above-mentioned high temperature side terminal heating pipeline 21 is supplied with to this accumulator 20 through bypass line 23, in this accumulator 20, mix with high-temperature-hot-water from above-mentioned bypass line 23 from the hot water of above-mentioned heating installation latent heat heat exchange pipe 14.And the low-temperature water heating of this accumulator 20 is supplied with to low temperature side terminal heating installation 4 through low temperature side terminal heating pipeline 24 on the one hand, supplies with to heat exchange pipe of heating installation 13 of above-mentioned main heat exchanger 11 by above-mentioned importing pipeline 25 on the other hand.In addition, the low-temperature water heating that comes out from low temperature side terminal heating installation 4 flows out to above-mentioned heating installation water return pipeline 27.Like this, by supply with the hot water of required temperature to high temperature side terminal heating installation 3 and low temperature side terminal heating installation 4, heating installation is moved.
In addition, in the occasion of having only above-mentioned high temperature side terminal heating installation 3 to carry out the heating installation operation, the moving valve 230 of above-mentioned low temperature capability switch heat does not open and still cuts out.But,, also can form minimum this valve of closing with gap in order to ensure the safety of Heating installation heat exchanger 1.In addition, having only above-mentioned low temperature side terminal heating installation 4 to carry out the occasion of heating installation operation, the moving valve 230 of low temperature capability switch heat of above-mentioned bypass line 23 is opened, but, the moving valve 300 of heat in high temperature side terminal heating installation 3 still cuts out, and the hot water of above-mentioned high temperature side terminal heating pipeline 21 is all supplied with to above-mentioned accumulator 20 by above-mentioned bypass line 23.
(freezing to prevent operation)
Below, freezing in the winter time prevented that operation from carrying out following explanation.Fig. 2 freezes to prevent the flow chart of the action that moves for expression.
As shown in Figure 2, at first, when the above-mentioned detected temperatures of freezing to prevent to move the low temperature thermistor of usefulness is (S100) below the solidification point T1 (for example 3 ℃), make heating installation pump P1 work (S200), secondly, judge whether the detected temperatures of above-mentioned heating installation high-temperature thermistor S1 is not more than maincenter ignition temperature T2 (for example 20 ℃) (S300).Be not more than the occasion of above-mentioned maincenter ignition temperature T2 (for example 20 ℃) in the detected temperatures of this heating installation high-temperature thermistor S1, make burner B1 burning and make Heating installation heat exchanger 1 work (S400).At this moment, the burner B1 of Heating installation heat exchanger 1 there is no need to generate the strong burning of the high-temperature-hot-water as common heating installation operation, but generates the low-temperature burning of the hot water of the temperature that can prevent the degree of freezing.Like this, the hot water circuit that is generated by above-mentioned Heating installation heat exchanger 1 is supplied to heating circulation circuit 2.
Then, through M1 burning time (for example 4 minutes) of regulation, M1 burning time then (S500) makes said burner B1 flame-out, stops the operation (S600) of Heating installation heat exchanger 1.Afterwards, according to the detected temperatures of at this moment low temperature thermistor, set and be used to make time interval M2 (for example 15 minutes～60 minutes) that heating installation pump P1 prolongs work (S700), as the time interval of pump work M2 one then (S800), just make heating installation pump P1 stop (S900), finish to freeze to prevent operation.
In addition, freeze to prevent that the control action that moves not only is confined to aforesaid way, also can be for example after the low-temperature burning of the operation of heating installation pump P1, Heating installation heat exchanger 1 begins, reach 7 ℃ occasion in the detected temperatures of low temperature thermistor, stop the control of the low-temperature burning of the operation of heating installation pump P1 and Heating installation heat exchanger 1.In addition, replace above-mentioned low temperature thermistor, also can begin the above-mentioned operation of freezing to prevent according to the detected temperatures that is arranged on the heating installation low temperature thermistor S2 in the heating circulation circuit 2.
But, in this heat supply water heating mechanism of qi, do not connecting above-mentioned low temperature side terminal heating installation 4, and, above-mentioned high temperature side terminal heating installation 3 for example blow in service like that, the moving valve 300 of heat of high temperature side terminal heating installation 3 self is closed, the unaccepted occasion of the supply of hot water, even carry out the above-mentioned operation of freezing to prevent, also because hot water does not flow into heating installation water return pipeline 27, so hot water is circulated in above-mentioned heating circulation circuit 2.Therefore, in this occasion, as shown in Figure 3, carry out following action.The flow process of this action is next step execution at above-mentioned steps S300.
At first, as shown in Figure 3, judge to have or not intelligence communication whether high temperature side terminal heating installation 3 is the condition of supplying (S310) of moving medium refusal hot water in air-supply.In addition, intelligence communication is certain signal exchange between high temperature side terminal heating installation 3 and the control device, and the signal of hot water is supplied with in the requirement of sending to control device from high temperature side terminal heating installation 3 just.Then, the occasion of this intelligence communication is being arranged, because high temperature side terminal heating installation 3 so motion flow is moved on to above-mentioned steps S400, makes Heating installation heat exchanger 1 carry out the low-temperature burning operation not for the condition of supplying of refusal hot water.
On the other hand, there be not the occasion of intelligence communication, because high temperature side terminal heating installation 3 is the condition of supplying of refusal hot water, moves the bathtub that whether carries out in the bathtub side loop (bathtub water return pipeline 64, bathtub supply channel 65 etc.) for confirmation so further confirm bathtub pump P2 whether being rotated and freeze to prevent operation (S320).In bathtub, have the occasion of remaining hot water etc., might produce under the environment that freezes, make bathtub pump P2 action, thus make bathtub side loop that bath water circulate in bathtub water return pipeline 64 and bathtub supply channel 65 freeze prevent to move.
And, in the occasion that bathtub pump P2 does not move, open the moving valve 220 (S350) of above-mentioned heat hot again, make Heating installation heat exchanger 1 carry out low-temperature burning operation (S400).Like this, the hot water of high temperature side terminal heating pipeline 21 passes through heating pipe line 22 again to be supplied with to heating installation water return pipeline 27, thus, hot water is circulated in above-mentioned heating circulation circuit 2.
On the other hand, in the occasion of bathtub pump P2 operation, whether the detected temperatures of confirming bathtub water supply thermistor S3 or bathtub thermistor S4 does not reach the temperature T 3 (for example 10 ℃) that can heat again (S330) as yet.Consequently: if the thermistor detected temperatures of bathtub does not reach the temperature T 3 that can heat again as yet, then open the moving valve 220 (S350) of above-mentioned heat hot again, make Heating installation heat exchanger 1 carry out low-temperature burning operation (S400); If the thermistor detected temperatures of bathtub is not less than the temperature T 3 that can heat again, then earlier bathtub pump P2 is stopped (S340), open the moving valve 220 (S350) of above-mentioned heat hot more then, make Heating installation heat exchanger 1 carry out low-temperature burning operation (S400).Thus, in that to prevent that bathtub from freezing in service,, also can prevent the heating phenomena again in the bathtub even beginning heating installation freezes to prevent operation.
In addition, at above-mentioned steps S340,, bathtub pump P2 is stopped though bathtub pump P2 is stopped, only open again the moving valve 220 of heat hot and do not make Heating installation heat exchanger 1 carry out the low-temperature burning operation, water is circulated in heating circulation circuit 2.
