Then, to boil the situation that executive condition is set up in warming operation execution, process heating executive condition being described and boiling when executive condition is set up simultaneously.
(the first embodiment of the process that simultaneously operates)
First, according to the flow chart shown in Fig. 2, illustrate that controller 150 performs, the hot water in the warming operation of warming-up 200 and heat accumulation water pot 11 boil running while the first embodiment of running process.
STEP1 ~ the STEP4 of Fig. 2 and STEP20 ~ STEP21 is the process that heating control portion 151 performs.In STEP1, heating control portion 151 judges whether heating executive condition is set up.Such as following condition can be set to heating executive condition: (1) user carries out heating to floor heating remote controller 201 and starts operation, (2) arrive the start time of the timing running set by floor heating remote controller 201.
In STEP1, when the executive condition that heats is set up, enter into STEP2.Heating control portion 151 performs following control: stop warm water from heating side mixing valve 48 to the circulation of heat pump bypass 42 side by heating side mixing valve 48, and allows warm water in heat pump heat exchanger 55 side circulation formation recurrent state.
In ensuing STEP3, heating control portion 151 allows heating circulation pump 111 become ON (startup), and in STEP4, allow heat pump 51 become ON.Thus, at heat pump heat exchanger 55 place, at the warm water of heating closed circuit 40 Inner eycle by the heating medium for heating at heat pump cycle loop 52 Inner eycle, and be fed into ground warming-up 200, heated by ground warming-up 200.

STEP5 ~ STEP9 and STEP30 is the process that operation control section 153 performs.Operation control section 153, in STEP5, measures the temperature (hereinafter referred to as heating reflux temperature Thb) flowing into the warm water of heat pump heat exchanger 55 from heating closed circuit 40 by heating reflux temperature sensor 45.
In ensuing STEP6, operation control section 153 judges whether boil executive condition sets up.Here, following condition is set to boils executive condition: when heat accumulation water pot 11 is in the state of disconnected hot water.The disconnected hot water conditions of heat accumulation water pot 11 can be judged by following situation: (1) supplying hot water auxiliary thermal source machine 70 is started working, (2) the mensuration temperature of tank temperature sensor 17 is reduced to disconnected hot water judgement temperature (such as boiling temperature-5 DEG C), and the mensuration temperature of (3) hot water temperature sensor 26 is reduced to disconnected hot water and judges temperature etc.Then, boil when executive condition is set up and enter into STEP7, boil executive condition when being false, turn back to STEP1.
In STEP7, operation control section 153 measures the temperature (hereinafter referred to as tank reflux temperature Ttb) flowing into the hot water of heat pump heat exchanger 55 from tank closed circuit 41 by tank reflux temperature sensor 68.Then, in ensuing STEP8, operation control section 153 judges whether temperature difference (absolute value) the Δ Tb of heating reflux temperature Thb and tank reflux temperature Ttb is less than 5 DEG C (are equivalent to regulation of the present invention and judge temperature).
Then, when temperature difference Δ Tb is less than 5 DEG C, be branched off into STEP30, operation control section 153 is allowed warming operation and is boiled running and operate simultaneously, and gets back to STEP1.Thus, be only limitted to allow warming operation under following occasion and boil running and operate simultaneously: the temperature Thb flowing into the warm water of heat pump heat exchanger 55 from heating closed circuit 40 is less with the temperature difference Δ Tb flowing into the temperature Ttb of the hot water of heat pump heat exchanger 55 from tank closed circuit 41, in heat pump heat exchanger 55, the impact that the heat loss at heat pump heat exchanger 55 place that the warm water of circulation and the heat exchange between the hot water of tank closed circuit 41 circulation cause in heating closed circuit 40 increases is less.
And on the other hand, when temperature difference Δ Tb is when being more than or equal to 5 DEG C, entering into STEP9, operation control section 153 forbids warming operation and boils running operating simultaneously, turns back to STEP1.Thus, under following occasion, forbid warming operation and boil running operating simultaneously: from heating closed circuit 40 flow into the warm water of heat pump heat exchanger 55 temperature Thb and flow into from tank closed circuit 41 heat pump heat exchanger 55 hot water temperature Ttb between temperature difference Δ Tb larger, make at heat pump heat exchanger 55 place, when the impact of the heat loss increase at heat pump heat exchanger 55 place that the heat exchange between the warm water and the hot water of circulation in tank closed circuit 41 of the circulation in closed circuit 40 that heats causes is larger.

Then, STEP54 ~ STEP59 and STEP80, STEP81 are the process that operation control section 153 performs.Operation control section 153, in STEP54, measures heating reflux temperature Thb by heating reflux temperature sensor 45.
In ensuing STEP55, operation control section 153 judges whether boil executive condition sets up.Enter STEP56 when boiling executive condition and setting up, and turn back to STEP50 when boiling executive condition and being false.
In STEP56, operation control section 153 measures tank reflux temperature Ttb by tank reflux temperature sensor 68.Then, in ensuing STEP57, operation control section 153 judges whether temperature difference (absolute value) the Δ Tb of heating reflux temperature Thb and tank reflux temperature Ttb is be more than or equal to 5 DEG C.
Further, be branched off into STEP80 when temperature difference Δ Tb is and is more than or equal to 5 DEG C, and enter into STEP58 when temperature difference Δ Tb is less than 5 DEG C.In STEP80, operation control section 153 performs following temperature adjustment and controls, and enter into STEP58: allow tank circulating pump 66 work, changed by heat pump mixing valve 59 and be supplied to the flow of the hot water of tank closed circuit 41 from heat accumulation water pot 11 and be back to the mixing ratio of flow of hot water of tank closed circuit 41 from hot water return loop 58, thus reduce temperature difference Δ Tb.

Thus, be only limitted to allow warming operation under following occasion and boil running and operate simultaneously: the temperature Thb flowing into the warm water of heat pump heat exchanger 55 from heating closed circuit 40 is less with the temperature difference Δ Tb flowing into the temperature Ttb of the hot water of heat pump heat exchanger 55 from tank closed circuit 41, in heat pump heat exchanger 55, the impact that the heat loss at heat pump heat exchanger 55 place that the warm water of circulation and the heat exchange between the hot water of tank closed circuit 41 circulation cause in heating closed circuit 40 increases is less.
And on the other hand, when temperature difference Δ Tb is when being more than or equal to 5 DEG C, entering into STEP59, operation control section 153 forbids warming operation and boils running operating simultaneously, turns back to STEP50.Thus, identical with the first embodiment, under following occasion, forbid warming operation and boil running operating simultaneously: from heating closed circuit 40 flow into the warm water of heat pump heat exchanger 55 temperature Thb and flow into from tank closed circuit 41 heat pump heat exchanger 55 hot water temperature Ttb between temperature difference Δ Tb larger, make at heat pump heat exchanger 55 place, when the impact of the efficiency decline of the heat pump 51 that the heat exchange between the warm water and the hot water of circulation in tank closed circuit 41 of the circulation in closed circuit 40 that heats causes is larger.
