As shown in figure 3, firstly, heat transmission control unit 420 judges whether it is the hot state (S1) transmitted of energy.It hot can transmit
State is judged based on above-mentioned temperature condition.In the case where being judged as is not that hot can transmit (S1: no), heat transmission control unit
420 make heat transmission pump 222 halted states (S5).Then, processing moves to step S11.
In the case where being judged as YES hot can transmit (S1: yes), during which judging part 410 judges whether be currently intergrade
(S2).In the case where being judged as currently is intergrade (S2: yes), control device 400 judges whether it is to stop in control at night
(S3).In the present embodiment, for example, carrying out hot transmission at dead of night with it when being judged as, heat transmission heat is carried out not as good as from morning
Whens the heat dissipation capacity of water storage bin 210, piping etc. is smaller etc., carrying out night stops control, 0 point at dead of night~9 points of period etc.
Forbid hot transmission.In addition, prediction calculates second day thermal-arrest condition etc., when being judged as early as possible to 210 heated conveying of hot water reservoir
In better situation, the control stopped without night can also be applied.
In the case where being judged as is not to stop in control at night (S3: no), heat transmission control unit 420 drives heat transmission pump
222(S4).Then, processing moves to step S11.In the case where on the other hand, in being judged as YES night stopping and controlling (S3:
It is), heat transmission control unit 420 makes heat transmission pump 222 halted states (S5).Then, processing moves to step S11.
In addition, being judged as (S2: no) in the case where being currently not intergrade, during which judging part 410 judge it is current whether
It is refrigeration phase (S6).Being judged as (S6: no) in the case where being currently not the refrigeration phase, that is, be judged as be currently heating period feelings
Under condition, heat transmission control unit 420 judges whether current time is to open from preset heat transmission time started t3 to supplying hot water
During beginning time t0 (S7).
In the case where during being judged as YES from heat transmission time started t3 to supplying hot water time started t0 (S7: yes),
Heat transmission control unit 420 drives 222 (S4) of heat transmission pump.Then, processing moves to step S11.On the other hand, it is not being judged as
In the case where during transmitting time started t3 to supplying hot water time started t0 from heat (S7: no), heat transmission control unit 420 makes heat
Transmission pump 222 is halted state (S5).Then, processing moves to step S11.
In addition, in the case where being judged as is currently the refrigeration phase (S6: yes), the air conditioner load of the presumption of presumption unit 430 from now on
(S8).Next, calculating configuration part 440 for air conditioner load (air conditioner load heat accumulative) from now on is that predetermined load Q1 is below
Time point calculates and is set as heat transmission time started t2 (S9).Then, heat transmission control unit 420 judge current time whether be
Set in step s 9 from heat transmit time started t2 to supplying hot water time started t0 during (S10).
In the case where during being judged as YES from heat transmission time started t2 to supplying hot water time started t0 (S10: yes),
Heat transmission control unit 420 drives 222 (S4) of heat transmission pump.Then, processing moves to step S11.On the other hand, it is not being judged as
In the case where during transmitting time started t2 to supplying hot water time started t0 from heat (S10: no), heat transmission control unit 420 makes
Heat transmission pump 222 is halted state (S5).Then, processing moves to step S11.
Herein, it shown in above-mentioned in flow chart, presumption unit 430 and calculates configuration part 440 and is only functioned in the refrigeration phase.
This is based on following reason.Fig. 4 is the figure for showing the air conditioner load of refrigeration phase, and Fig. 5 is the figure for showing the air conditioner load of heating period.
As shown in figure 4, in the refrigeration phase, due to high in daytime temperature, the refrigeration load on daytime increases, with process
Night is moved at night, there is the tendency of decline.Presumption unit 430 is based on storage content, estimates refrigeration load shown in Fig. 4.It calculates
Configuration part 440 based on the refrigeration load estimated by presumption unit 430, such as will become predetermined load Q1 or less at the time of t2 calculating be
The heat transmission time started.In addition, at the time of moment t2 is more late than moment t3.
On the other hand, as shown in figure 5, in recent years using passive building, high heat-insulated and high airtight building, heating load
Has the tendency that decline.In such building, as shown in figure 5, the heating load on warm daytime is for example essentially a zero, from night
Several heating loads can be generated during by night to morning.Since such heating load is small, such as 1 day air conditioner load is
Predetermined load Q1 is not hereinafter, therefore, presumption unit 430 and calculating configuration part 440 function.At this point, the heat transmission time started is
T3 at the time of decision according to design, the time longest of heat transmission.
Referring again to Fig. 3.In step s 11, heating source control unit 450 judges whether current time is heating from setting
The heating interval (S11) of time started t1 to supplying hot water time started t0.In the case where being judged as YES heating interval (S11:
It is), heating source control unit 450 judges whether the coolant-temperature gage in hot water reservoir 210 is predetermined temperature or more (S12).Judging
Not to be in the case where predetermined temperature or more (S12: no), heating source control unit 450 is heated (S13) using heating source 230.
It is later, shown in Fig. 3 that processing terminate.On the other hand, (S11: no) or judgement in the case where being judged as not is heating interval
To be in the case where predetermined temperature or more (S12: yes), heating source control unit 450 does not drive heating source 230 and without heating
(S14).It is later, shown in Fig. 3 that processing terminate.
In the above manner, air-conditioning involved according to the present embodiment and hot-water supply system 1, due to the heat in setting
Transmission time started t2, t3 start hot transmission, terminate hot transmission in supplying hot water time started t0, therefore, carry out heat by limiting
The heat of heat storage tank 120 can be sent to hot water reservoir 210 in the case where not interfering air-conditioning to utilize by the time of transmission,
The water in hot water reservoir 210 is set to heat up.Also, since the supplying hot water time started t0 in setting terminates hot transmission, it examines
Heat transmission time started t2, the t3 for considering next time make the water low temperature in hot water reservoir 210 to which heat utilization effect can be improved
Rate.Thus it is possible to reduce the influence utilized to air-conditioning, and the consumption that non-renewable energy can be improved cuts down effect.
Also, since the supplying hot water time started t0 in setting terminates hot transmission, heat surplus in heat storage tank 120
In the case where, it can be ensured that it is used for second day etc. air-conditioning.
In addition, due to estimating air conditioner load from now on, presumptive air conditioner load starts to calculate and set heat transmission
Time t2, therefore, in the case where air conditioner load is small, heat transmission time started t2 shifts to an earlier date, in the case where air conditioner load is big, heat
Transmit time started t2 delay.It therefore, can be under conditions of not interfering more accurately air-conditioning to utilize by the heat of heat storage tank 120
It is sent to hot water reservoir 210, the water in hot water reservoir 210 is made to heat up.Air-conditioning utilized thus it is possible to further decrease
It influences, the consumption for improving non-renewable energy cuts down effect.
In addition, in the case where being judged as YES intergrade, with heat transmission time started t2, t3 and supplying hot water time started t0
Hot transmission is independently carried out, therefore, almost without using the intergrade of air-conditioning, can energetically use the heat in heat storage tank 120
Amount makes the water in hot water reservoir 210 heat up, and can further increase the reduction effect of primary energy consumption amount.
In addition, since the temperature for the water being judged as in hot water reservoir 210 in the heating interval set is not up to makes a reservation for
It is heated in the case where more than temperature using heating source 230, is not to be sufficient to correspond in the temperature prediction based on water therefore
In the case where the heat of heat supply water load, it can be heated using heating source 230 to correspond to heat supply water load.In addition, due to
Terminated using the heating of heating source 230 in supplying hot water time started t0, accordingly, it is considered to next time heat transmission time started t2,
T3 can make the water low temperature in hot water reservoir 210 and improve efficiency of heating- utilization.
