Below, about the run action of heat pump-warm water supply and floor heating device of the present invention, with reference to thermal source loop 40, hot water supply loop 45 and the floor heating loop 50 of Fig. 1, the flow chart of key diagram 2～Fig. 5.
Fig. 2 represents the temperature controlled flow chart in the floor heating running.
At first, when the temperature that sends to (step 71) plate heating simultaneously on the product body when the commencing signal that after the floor heating mode of selecting floor heating remote controller 57 floor heating turned round was selected (step 72), the beginning floor heating was with heat pump running (step 73).
That is, use in the thermal source loop 41 at floor heating, cold medium open and close valve 2a closes, cold medium open and close valve 2b opens, and carries out floor heating with adding heat run in the compressor 1a → heat pump circuit of cold medium open and close valve 2b → floor heating with cold medium tube 8a → decompressor 4c → evaporimeter 5a → compressor 1a.
On the other hand, in floor heating loop 50, selection by floor heating remote controller 57, open floor heating open and close valve 11, any one of 12 or both sides, by the running of floor heating with circulating pump 9, at floor heating groove 10 → floor heating circulating pump 9 → floor heating heat-transfer pipe 8b → floor heating open and close valve 11,12 → floor heating hot water supply pipe joint 32,33 → heat release pipe 35a, 36a → floor heating uses recurrent canal joint 34 → floor heating with thermal medium (not shown) circulation in the loop circuit of groove 10, with the thermal medium floor heating device 35 of heating heat exchanger 8 heat absorptions in floor, 36 heating, the heat release floor.
Thermal medium for circulating floor heating loop 50, detect the go to temperature of floor heating with going to temperature thermometer 8c with the export department of heat-transfer pipe 8b, detect the return temperature of floor heating with returning temperature thermometer 10a with the inlet portion of groove 10, with each temperature information at any time to the transmission of running control module.
Then, when operation is risen in floor heating running beginning back (step 74), the floor heating of the remote controller by high slightly setting according to respect to temperature stabilization the time is gone to desired temperature and is moved continuously, shorten floor heating and arrive the time that is fit to temperature, when local plate temperature reaches the stable state that is fit to temperature, switch to and go to temperature control operation (step 75).
Go to temperature control operation (step 75), reduce the floor heating of remote controller and go to desired temperature, and set floor heating according to the difference that the floor heating that the floor heating of remote controller returns desired temperature and physical device returns temperature and go to the temperature objectives value, its details are described now.
At first, when from bringing into operation to going to temperature control operation when switching, the floor heating that carries out physical device returns temperature and returns the comparison of desired temperature by the floor heating that the input of remote controller is set, when satisfying " return temperature 〉=return desired temperature " (step 76), the new temperature objectives value of going to as " old go to temperature objectives value-(return temperature-return desired temperature) " (step 76a).And then, if new go to the temperature objectives value below lower limit temperature (for example 30 ℃) (step 76b), then new gone to the temperature objectives value as 30 ℃ (step 76c).In addition, when satisfying " return temperature＜return desired temperature-2 ℃ " (step 77), the new temperature objectives value of going to as " old go to temperature objectives value+(return desired temperature-return temperature) " (step 77a).And then, if new go to the temperature objectives value more than ceiling temperature (for example 70 ℃) (step 77b), then new gone to the temperature objectives value as 70 ℃ (step 77c).
Go to temperature control operation, repeat with predetermined distance (for example 10 minutes), return temperature by the judgement renewal of returning temperature, just can often remain on the temperature control that is fit to temperature, get rid of unnecessary heating operation, can realize that the good necessary minimal low temperature of effect coefficient (COP) moves continuously.In this occasion, lower limit temperature and ceiling temperature in any occasion, all are to be made as this temperature with interior boundary value, rather than the control temperature during floor heating common, the effect of the harmless thus raising effect coefficient (COP) by low temperature control of the present invention.
By the operation of timer or remote controller, when output floor heating running stop signal (step 78), stop floor heating and turn round with heat pump with circulating pump 9 and floor heating, finish floor heating running (step 79).
According to Fig. 1 and Fig. 3 the concrete example that adds heat run control according to the floor of flow chart is described below.
In the present embodiment, go to temperature as floor heating, use the outlet temperature of using the floor heating of going to temperature thermometer 8c detection to use heat-transfer pipe 8b, return temperature, use the inlet temperature of using groove with the floor heating that returns temperature thermometer 10a detection as floor heating.
In addition, the invention is not restricted to present embodiment, floor heating is gone to temperature as long as then have same effect between the inlet that exports to floor heating plate 35,36 of floor heating with heat-transfer pipe 8b, and floor heating returns temperature and needs only at floor heating and then have same effect with the inlet of groove 10 between the inlet of floor heating plate 35,36.
Fig. 3 is that transverse axis represents that floor heating running elapsed time, the longitudinal axis represent an embodiment of the floor heating running control of compressor rotary speed and heat medium temperature.
At first, by floor heating remote controller 57, set floor heating in the floor heating loop 50 with the desired temperature (hereinafter referred to as returning desired temperature) of the thermal medium of the entrance side of groove 10 and floor heating initial temperature desired value (hereinafter referred to as initially going to the temperature objectives value) with the thermal medium of the outlet side of heat exchanger 8.Here, for example return desired temperature, have height (50 ℃), in (40 ℃), low (30 ℃) 3 selection modes, corresponding each mode determines to go to the temperature objectives value.Below with regard to its return desired temperature selected in (40 ℃), initially going to the occasion that the temperature objectives value is made as 60 ℃, the action of the control module 55 that turns round is described.
Because originally stipulated time of operation is the operation of rising, and initially goes to the temperature objectives value and be set at high 60 ℃,, can reach stable operation ahead of time so can shorten the temperature rise time.
Then, when beginning from operation through setting-up time (for example 30 minutes), (A point) switched in the temperature control operation of going to floor heating plate 35,36, and that relatively returns desired temperature and actual thermal medium returns temperature (be designated hereinafter simply as and return temperature), determines the new temperature objectives value of going to.At the A point, because return temperature (50 ℃) than returning desired temperature (40 ℃) height, so the new temperature objectives value of going to is for initially going to temperature objectives value (60 ℃)-[return temperature (50 ℃)-return desired temperature (40 ℃)]=50 ℃.
After the A point (30 minutes), for example, every through just returning temperature in 10 minutes and returning the comparison of desired temperature (40 ℃), but behind 40,50,60 minutes of transverse axis, return temperature＜return desired temperature, and return temperature 〉=[return desired temperature-2 ℃], the heating-up temperature of expression design temperature and thermal medium is almost consistent, can not carry out unnecessary temperature and switch, continue stable floor heating running.
And then, shown in the B point, returning temperature (35 ℃) than [returning-2 ℃ of desired temperatures (40 ℃)] also low occasion, the new temperature objectives value of going to becomes above-mentioned new temperature objectives value (50 ℃)+[return desired temperature (40 ℃)-return temperature (35 ℃)]=55 ℃ of going to.
Tmin (30 ℃) and Tmax (70 ℃), the boundary of temperature objectives value is gone in expression, exceeds the occasion of this scope in the result of calculation of the setting formula of going to temperature, and the new temperature objectives value of going to is taken as 30 ℃ or 70 ℃.
In addition, Fig. 3 goes to the temperature change action for what the floor heating plate was described, has made the temperature curve in the present embodiment, and the content of these charts such as time, temperature setting, temperature objectives value changes according to condition enactment certainly.
In addition, in the present embodiment, in explanation, the remote controller design temperature as returning desired temperature, but be not limited thereto, for example, can as low (30 ℃), in (40 ℃), high (50 ℃) as predefined temperature, also can set and flow through the temperature of floor heating with the ad-hoc location of the thermal medium of heat exchanger.
As above-mentioned, the temperature of returning by frequent detection physical device, every predetermined distance (for example 10 minutes) upgrades and goes to the temperature objectives value according to returning temperature and returning the comparison of desired temperature, can carry out the temperature control of floor heating of the variation of corresponding physical device load.
Effect coefficient (COP) when with Fig. 4 the floor warming operation being described below.
Fig. 4 during with floor heating thermal medium to go to temperature (floor heating with the outlet side temperature of heat-transfer pipe) be transverse axis, be the longitudinal axis with effect coefficient (COP), represent to go to the dependency relation of temperature and effect coefficient.In the identical occasion of service condition, in the floor heating running, it is high more to go to the low more effect coefficient of temperature as shown in Figure 4.
In the present invention, because the shortening of attention rise time is established height a little and is gone to temperature objectives value (50～60 ℃) when the floor heating initial launch, so it is 2～2.5 low slightly that the effect coefficient is about, but behind temperature stabilization, be made as 30～40 ℃, can bring up to 3.5～4.0 to the effect coefficient initially going to the temperature objectives value.
Below, the hot water supply running when illustrating that with Fig. 5 the hot water that passes through Kitchen tap uses.When opening Kitchen tap 23 and bring into use hot water (step 81), feedwater water sensor 15 detects flow, carry out the judgement (step 82) that hot water supply begins, then being judged to be hot water supply as flow more than a certain amount of begins, running control module 55, beginning starting compressor 1a, 1b, beginning heat pump running (step 83), by Water supplying tube joint 13, pressure-reducing valve 14, feedwater water sensor 15, water non-return valve 16, feedwater side heat-transfer pipe 3c, 3d, hot water supply mixing valve 19, hot water water mixing valve 20, flow rate regulating valve 21, kitchen hot-water outlet pipe's joint 22, the hot water supply loop of Kitchen tap 23, beginning hot water supply (step 84).

That is, sending into to cold side medium heat-transfer pipe 3a, the 3b of heat exchanger for hot water supply 3 with the cold medium of HTHP of compressor 1a, 1b compression, the feedwater that heating is flowed in cold side medium heat-transfer pipe 3a, 3b goes out to hot water water mixing valve 20 effluents, but because the cold medium that operation beginning back is sent into to heat exchanger for hot water supply 3 does not fully become HTHP, temperature is low, and heat exchanger for hot water supply 3 all cools off, so it is insufficient to add the heating efficiency of hot water.Along with the cold medium of the process of time becomes HTHP, accompany with it, the thermal discharge of the next self cooling medium that takes place increases, heating efficiency for water increases gradually, but begin when the operation that the hot water supply temperature reaches suitable temperature (about 40 ℃) is risen from this operation, the hot water of the temperature (for example 60～65 ℃) more than the suitable temperature that outflow is put aside in the hot water holding tank in advance, with hot water supply mixing valve 19 with from feedwater side heat-transfer pipe 3c, the hot water that 3d comes mixes makes the high-temperature water that is fit to more than the temperature, and then with an amount of cold water that mixes to come self-water-supply water sensor 15 sides of hot water water mixing valve 20 be transferred to use be fit to temperature after, by flow rate regulating valve 21, kitchen hot-water outlet pipe's joint 22 is supplied with hot water to Kitchen tap.
In this hot water supply running, the floor heating of service chart 1 is used thermal source loop 42 with thermal source loop 41 and hot water supply together, compressor 1a, 1b, carry out rotating speed control by the running control module, in the high summer of supplying with from the water pipe at water source etc. of feed temperature because with little add heat can so that rotating speed is low, in feed temperature low winter, because need the big heat that adds, move so improve rotating speed.
In the hot water memory type heat-pump-type hot water supply apparatus of prior art, make compressor come high temperature storage hot water with 3000～4000 rev/mins of runnings.The occasion of using at floor heating because and store the hot water running and make the high-temperature water circulation with 3000～4000 rev/mins of runnings equally, so compare in the light floor heating running of load frequent interrupted compressor with the hot water supply running.
Relative therewith, moment of the present invention the formula heat pump-warm water supply and floor heating device, with the compressor rotary speed running corresponding with the hot water supply applied load, as the moment burning water heater, supply with hot water, but, when floor heating turns round, unlike hot water memory type heat-pump-type hot water supply apparatus, rotate intermittent working with high speed, the compressor but low speed turns round continuously is so can raise the efficiency (COP).
Return Fig. 5, after hot water supply begins (step 84), detection data according to feedwater water sensor 15, feed temperature meter 37, hot water supply thermometer 38 etc., running control module 55 carries out the adjustment (step 85) of hot water supply temperature and flow, continues proper temperature, the suitably hot water supply running of flow.And then, repeat the judgement (step 86) of hot water supply temperature and flow, as in regulation, then continue hot water supply and close (step 87) up to tap.When closing Kitchen tap 23 when finishing hot water and using (step 88), running control module 55 stops heat pump running (step 89), finishes hot water supply running (step 80).
