When tap 5 is opened, when water is fed into feed pipe 2 from water pipe, the supplying hot water control part 52a of linkage unit controller 50a performs supplying hot water operation.At this moment, supplying hot water control part 52a changes the aperture of heat source machine flow variation valve 13, performs mixing temperature adjustment and controls, and makes to flow out the hot water with first object supplying hot water temperature from tap 5.Described mixing temperature adjustment controls to refer to change and is supplied to the flow of the water of heat source machine 10 side from feed pipe 2 and is supplied to the mixing ratio of flow of water of supplying hot water bypass pipe 45 side from feed pipe 2.In addition, in supplying hot water operation performs, heating flow variation valve 44 is in full-gear substantially.
Here, water can have been identified whether by the difference between thermal source flow Fin and heating flow Fc and be supplied to feed pipe 2 from water pipe.As Fth (water supply decision content) < Fin-Fc, supplying hot water control part 52a identifies that water is just fed into feed pipe 2 from water pipe.
Then, illustrate when being performed heating operation by heating control portion 51a, the heat source machine flow when the supplying hot water being realized first object supplying hot water temperature by supplying hot water control part 52a execution operates changes the setting order of valve 13 aperture.
About the hot water flowed in the circulation pathway of hot water supply and heating system 1a, the relation of following formula (1) is set up.
Fw×T1set＝Tout×(Fw－Fb)+Tw×Fb···(1)
Wherein, Fw: the flow (water supply flow) being supplied to the water of feed pipe 2 from water pipe, T1set: first object supplying hot water temperature, Tout: the temperature (thermal source leaving water temperature) being supplied to the hot water of heat supply water pipe 3 from heat exchanger 11, Fb: flow (the supplying hot water bypass flow circulating in the water of supplying hot water bypass pipe 45, Fb=Fw-Fin+Fc), Tw: the temperature (supply water temperature) being supplied to the water of feed pipe 2 from water pipe.
After above-mentioned formula (1) is out of shape, following formula (2) can be obtained.
Fb＝Fw×(Tout-T1set)/(Tout-Tw)···(2)
In addition, between water supply flow Fw, supplying hot water bypass flow Fb and heating flow Fc, the relation of following formula (3) is set up.
Fin＝Fw-Fb+Fc···(3)
When above-mentioned formula (2) is substituted into above-mentioned formula (3), following formula (4) can be obtained.
Fin＝Fw-Fw×(Tout-T1set)/(Tout-Tw)+Fc
＝Fw×(T1set-Tw)/(Tout-Tin)+Fc···(4)
Here, the corresponding heat source machine flow of ratio of flow (supplying hot water bypass flow) Fb of the flow (=Fin-Fc) flowing to the water of heat source machine 10 side from feed pipe 2 and the branch part A of supplying hot water bypass pipe 45 and the water that flows to supplying hot water bypass pipe 45 side from branch part A changes the aperture of valve 13 and changes.That is, the relation of following formula (4) is set up.
Fin-Fc＝Fw·k···(5)
Wherein, k: the allotment ratio (0≤k≤1) flowing to the water of heat source machine 10 side at branch part A place that sets according to the aperture of heat source machine flow variation valve 13.
Therefore, it is possible to calculate water supply flow Fw according to the aperture of the detected value of thermal source flow Fin, the detected value of heating flow Fc and heat source machine flow variation valve 13.Supplying hot water control part 52a regulates heat source machine flow to change the aperture of valve 13 based on the detected temperatures of thermal source leaving water temperature Tout, makes the thermal source flow Fin detected by heat source machine flow sensor 12 consistent with the calculated value obtained by above-mentioned formula (4).In this way, the temperature being supplied to the hot water of tap 5 from heat supply water pipe 3 is controlled so as to first object supplying hot water temperature T1set.
In addition, in the mixing temperature adjustment control that supplying hot water control part 52a performs, also can receive the second target supplying hot water temperature data to replace the detected temperatures data of thermal source leaving water temperature Tout from heat source machine 10, and the second target supplying hot water temperature is used as the Tout in above-mentioned formula (1).
Then, according to the flow process shown in Fig. 2, the process that priority acccess control portion 53a when operating supplying hot water operation and heating operation at the same time performs is described.When operating supplying hot water operation and heating operation at the same time, priority acccess control portion 53a performs the flow process (step) shown in Fig. 2 repeatedly.
In the STEP1 of Fig. 2, priority acccess control portion 53a calculates the heat, i.e. the supplying hot water heat Qw that consume in supplying hot water operation by following formula (6).
Qw＝Fw×(T1set-Tin)···(6)
Wherein, Qw: supplying hot water heat, Fw: the flow (water supply flow) being supplied to the water of feed pipe 2 from water pipe, T1set: first object supplying hot water temperature, Tin: thermal source inflow temperature.
In ensuing STEP2, priority acccess control portion 53a calculates the heat, i.e. the heating-amount Qc that consume in heating operation according to following formula (7).
Qc＝Fc×(Tout-Tc)···(7)
Wherein, Qc: heating-amount, Fc: heating flow, Tout: thermal source leaving water temperature (towards heating temperature), Tc: heating returns temperature.
In ensuing STEP3, priority acccess control portion 53a according to communicating between linkage unit controller 50a with heat source machine controller 20, maximum heat (maximum heat that heat exchanger 11 can obtain because of the burning of the burner) Qmax of setting heat source machine 10.
In STEP4 subsequently, priority acccess control portion 53a judges whether the total heat of supplying hot water heat Qw and heating-amount Qc is more than maximum heat Qmax.Further, when the total heat of supplying hot water heat Qw and heating-amount Qc is more than maximum heat Qmax, STEP5 is entered.When the total heat of supplying hot water heat Qw and heating-amount Qc is less than maximum heat Qmax, be branched off into STEP7.
In STEP5, priority acccess control portion 53a judges whether to be set to supplying hot water operator precedence by heat source machine remote controller 30.Here, when operating supplying hot water operation and heating operation at the same time, user operates heat source machine remote controller 30, can carry out the setting of supplying hot water operator precedence or heating operator precedence.Described supplying hot water operator precedence refers to that supplying hot water operation will have precedence over heating operation, and described heating operator precedence refers to that heating operation will have precedence over supplying hot water operation.
Further, priority acccess control portion 53a is according to communicating between heat source machine controller 20 with linkage unit controller 50a, and identifying whether is the setting of supplying hot water operator precedence.In addition, this setting supplying hot water operator precedence and heating operator precedence by heat source machine remote controller 30 forms and is equivalent to priority service configuration part of the present invention.
When being set to supplying hot water operator precedence, be branched off into STEP20.Then, priority acccess control portion 53a performs the side in following (a) and (b) or performs (a) and (b) simultaneously, thus carry out supplying hot water priority acccess control, reduce the flow of the hot water circulated in heating pad pipe 46, then enter STEP7.
A () reduces the rotary speed of pump 62.
B () reduces the aperture of heating flow variation valve 44.
In addition, change the rotary speed of pump 62 or the aperture of heating flow variation valve 44, thus this formation changing the flow of the hot water circulated in heating pad pipe 46 is equivalent to heating flow variation portion of the present invention.
By supplying hot water priority acccess control, reduce the flow circulating in the hot water of heating pad pipe 46, thus the flow being mixed into the hot water feed pipe 2 from heating pad pipe 46 is reduced, circulate in heat exchanger 11 and reduced by the flow of the hot water heated.Therefore, it is possible to the temperature of the hot water flowing to heat supply water pipe 3 from heat exchanger 11 maintained on the second target supplying hot water temperature T2set, thus prevent the temperature of the hot water supplied from tap 5 lower than first object supplying hot water temperature T1set.
On the other hand, when not setting supplying hot water operator precedence in STEP5 (when being configured to heating operator precedence), STEP6 is entered.Further, priority acccess control portion 53a performs a wherein side of following (c) and (d), carries out heating priority acccess control, reduces the flow of the water being fed into heat exchanger 11 from water channel via feed pipe 2, and enter into STEP7.
C () reduces first object supplying hot water temperature T1set.By reducing first object supplying hot water temperature T1set, due to be supplied to feed pipe 2 from water channel water in the middle of flow to the water of supplying hot water bypass pipe 45 side ratio increase, the flow being supplied to the hot water of heat exchanger 11 from feed pipe 2 reduces.
D () reduces the aperture of water supply flow variation valve 80.By reducing the aperture of water supply flow variation valve 80, the flow being supplied to the water of feed pipe 2 from water channel is reduced, thus the flow being supplied to the hot water of heat exchanger 11 from feed pipe 2 is reduced.
Reduced the flow of the water being fed into heat exchanger 11 from water channel via feed pipe 2 by heating priority acccess control, circulate in heat exchanger 11 and reduced therefrom by the flow of the hot water heated.Therefore, the temperature of the hot water flowing to heat supply water pipe 3 from heat exchanger 11 can be maintained the second target supplying hot water temperature T2set, and supply has the hot water of the second target supplying hot water temperature T2set from heat supply water pipe 3 to heating pad pipe 46, and heated by heating device 60.
In addition, when reducing first object supplying hot water temperature T1set by the process of above-mentioned (c) thus performing supplying hot water operation, the first object supplying hot water temperature T1set after being lowered can be shown to the display part of heat source machine remote controller 30.Or, notify reduce first object supplying hot water temperature T1set because of heating priority acccess control thus the supplying hot water temperature of tap 5 is declined this situation by display or voice.
In STEP7, priority acccess control portion 53a judges whether supplying hot water operation or heating operation stop thus being in the independent operation of supplying hot water operation or heating operation.Further, be in operate separately time, enter STEP8, end process.On the other hand, when be not in operate separately time (supplying hot water operation and heating operation while operation be in persistent state time), return STEP1, priority acccess control portion 53a performs the later process of STEP1 again.
