The Teat pump boiler that constitutes as described above just below describes its action, effect.
At first, if make refrigerant loop 5 runnings according to storage hot water CRANK PULSES, then cold-producing medium is compressed at compressor 1, become HTHP, by heating and heat release at 2 pairs of water of radiator, become low-temp low-pressure by decompressor 3, from atmosphere, absorb heat and evaporate, turn back to compressor 1 by air heat exchanger 4.In water loop 9, two-port valve 8 is opened, and supplies to running water the hot-water cylinder 6 from feed pipe 10, by circulating pump 7 from the underfeed of hot-water cylinder 6 to radiator 2, heated by radiator 2.By radiator 2 heating, become the hot water of high temperature, pass two-port valve 8, flow into the top of hot-water cylinder 6, store hot water successively from top.And, if the temperature of water that records the inlet of radiator 2 by temperature sensor 21 reaches setting, then owing to be stored in the temperature that the temperature of the warm water in the hot-water cylinder 6 reaches regulation, so, compressor 1 is shut down, refrigerant loop 5 is shut down.Though the hot water temperature who supplies with from heat supply water terminal 15 is below 45 ℃ usually, in the present invention, when the running of storage hot water, the heating-up temperature that makes water loop 9 is more than 60 ℃, increases the amount of stored heat of giving hot-water cylinder 6.So, be more than 60 ℃ owing to make the heating-up temperature of water loop 9, set the temperature that is stored in the warm water in the hot-water cylinder 6 to such an extent that compare from the temperature height of the warm water of terminal 15 supplies of heat supply water, can reduce the capacity of hot-water cylinder 6, can make the volume of hot-water cylinder 6 little.
Occasion supply with from hot water to heat supply water terminal 15 in heat supply water loop 17, makes the state of feed water valve 18 for opening, and flow into the pressure of the running water of hot-water cylinder 6 by the feed pipe 10 from hot-water cylinder 6 bottoms, makes the warm water of hot-water cylinder 6 flow out to hot-water outlet pipe 11.The hot water that flows out from hot-water cylinder 6 passes the 1st mixed water valve 12, mixes with the running water of the low temperature that flows into from tap water pipe line 13 at the 2nd mixed water valve 14.The 2nd mixes the output valve of water valve 14 according to hot water outlet temperature sensor 24, to adjusting from the warm water of hot-water cylinder 6 and the mixed proportion of running water, is the temperature of regulation, and heat supply water end 15 is arrived in hot water supply.
And, supplying with the occasions of hot water with 45 ℃ from heat supply water terminal 15, because the running water temperature is according to the difference in season and change to some extent, so, according to the required ability of heating of running water temperature and outer temperature degree change Teat pump boiler.Particularly, in the winter time,, also have outside air temperature low, so the heating efficiency of Teat pump boiler has reduced because the running water temperature is low.Therefore, must improve the heating-up temperature of water loop 9, increase the amount of stored heat of giving hot-water cylinder 6.Therefore, can the heating-up temperature of water loop 9 changed in 60 ℃ to 90 ℃ scope, change the amount of stored heat of giving hot-water cylinder 6 according to outside air temperature and running water temperature.
Below, the running action that the subtend bathtub is supplied with hot water describes.If begin to supply with hot water to bathtub 16 according to signal from hot water to bathtub that supply with, then refrigerant loop 5 entrys into service, the setting heating-up temperature that makes water loop 9 is 35～45 ℃.Owing to can reduce the compression ratio of refrigerant loop 5 thus, reduce the power consumption of compressor 1, so, can turn round efficiently.In addition, when supplying with hot water by refrigerant loop 5 runnings, the warm water of hot-water cylinder 6 also mixes water valve 12 by the 1st and supplies to heat supply water loop 17, therefore, mix water valve 14 the 2nd and mixes with running water, can make quantity delivered from the warm water of set points of temperature (for example 35 ℃～45 ℃) to bathtub 16 that supply with is maximum.Consequently, can supply with hot water to bathtub 16 at short notice.
Below, the heat supply water transport rotation under the few situation of the surplus hot water's quantitative change in the hot-water cylinder 6 is described.Surplus hot water's quantitative change in supplying with hot water, hot-water cylinder 6 repeatedly is few, surplus hot water's temperature sensor 23 is output as the occasion below the setting, send storage hot water CRANK PULSES, refrigerant loop 5 runnings, output valve according to heat supply water temperature sensor 22, the flow of control circulating pump 7, supply with hot water with the heating-up temperature of setting, be stored in the hot-water cylinder 6.
In the storage hot water operation process of refrigerant loop 5 runnings, the occasion of opening at heat supply water end 15, close two-port valve 8, through the 1st mixed water valve 12, mixed water valve 14 the 2nd and mix with the running water of the low temperature that flows into from tap water pipe line 13 by radiator 2 warmed-up warm water.Mix water valve 14 the 2nd,, adjust the mixed proportion of warm water and running water, be the temperature of regulation, supply with hot water from heat supply water terminal 15 according to the output valve of hot water outlet temperature sensor 24.In this case, warm water use more, only use the occasion of refrigerant loop 5 heating efficiency deficiencies, also supply with hot water from hot-water cylinder 6, mix water valve 12 the 1st and mix, the hot water amount increases supply.And, if close heat supply water end 15, then open two-port valve, close the 1st and mix water valve 12, continue the running of storage hot water.
Fig. 2 is an example of heat supply water load model, and the heat of supposing the supply hot water of every day is 49320kJ (11780kcal), 1 year was 18GJ (4.3Gcal) (being equivalent to IBEC L pattern).
Fig. 3 is the heat supply water load model to Fig. 2, the running water temperature of supposing winter is that 5 ℃, the capacity of hot-water cylinder 6 are 100 liters, 45 ℃ heating efficiency Q is 10kW, 65 ℃ heating efficiency Q is 8.9kW, and tentative calculation is at the curve map of the variation of the delayed heat water yield of carrying out the hot-water cylinder 6 under the working order as described above.
Fig. 4 is that 45 ℃ heating efficiency Q of hypothesis is the curve map that the capacity of the hot-water cylinder 6 under the working order as described above is carried out in 5kW, 10kW, 20kW, tentative calculation.Be equivalent to IBEC L pattern, heating efficiency is that 10kW needs 90 liters, is the capacity that 20kW needs 50 liters hot-water cylinder 6.Being 73970KJ (17670kcal), 1 year at the heat of heat supply water of hypothesis every day is the occasion of 27GJ (6.45Gcal) (be equivalent to IBEC L pattern 1.5 times), and heating efficiency is that 10kW needs 160 liters, is the capacity of the hot-water cylinder 6 of 110 liters of 20kW needs.Supposing that the storage hot water temperature is 85 ℃ a L pattern, heating efficiency is that 10kW can make the capacity of hot-water cylinder 6 reduce to 70 liters, is that 20kW can reduce to 32 liters.
So, owing to, can predict the capacity of hot-water cylinder 6 according to the heat supply water load of hypothesis and the heating efficiency of Teat pump boiler, so, if make the size of hot-water cylinder 6 more than the capacity, then can not can produce disconnected hot water phenomenon at this.
According to present embodiment, because by these runnings, when heat supply water end 15 is supplied with hot water slightly, do not make refrigerant loop 5 runnings, the heat supply water yield big supply with the occasion that the surplus hot water of the occasion of hot water and hot-water cylinder 6 tails off to bathtub 16, make refrigerant loop 5 runnings, so, in the running that can reduce compressor 1, stop number of times, when improving the reliability of machine, can reduce the size of hot-water cylinder 6, can finish at short notice to bathtub 16 and supply with hot water.
In addition, as shown in Figure 5, by two-port valve 8 is replaced as triple valve 19, according to the output switch three-way valve 19 of heat supply water temperature sensor 22, the lower occasion of temperature of the water of the outlet of radiator 2 when starting refrigerant loop 5 grades, make the bottom that is turned back to hot-water cylinder 6 by radiator 2 warmed-up water, in the occasion that approaches to set by the storage hot water temperature of the temperature of radiator 2 warmed-up water, switch three-way valve 19, make warm water turn back to the top of hot-water cylinder 6, then can make the water in the hot-water cylinder 6 keep higher temperature.
Fig. 6 is the structure chart of the Teat pump boiler of the 2nd embodiment of the present invention.The structure member identical with Fig. 1 uses prosign, and omits its explanation.
In Fig. 6, the 2nd export pipeline that mixes water valve 14 is connected with heat supply water terminal 15, mix water valve 12 and the line branching pipe of the 2nd mixed water valve 14 and the branched pipe of tap water pipe line 13 with connecting the 1st, mixing water valve 20 with the 3rd connects, the 3rd export pipeline that mixes water valve 20 is connected with bathtub 16, constitutes heat supply water loop 17.The 25th, bathroom temperature at discharging condensate sensor, the 26th, the outer temperature degree sensor of detection outside air temperature.
In the Teat pump boiler that as above, constitutes, when common running, because mixing water valve 19 by the 2nd mixed water valve 14, bathtub 16 by the 3rd, heat supply water terminal 15 is connected with tap water pipe line 13 with water loop 9 respectively, so, to the occasion of heat supply water terminal 15 and bathtub 16 supply hot water, can supply with hot water at the same time with different temperature.It is identical with the embodiment 1 that illustrates with Fig. 1 with effect that work is rotated in other heat supply water transport, omits its explanation.
Below, the heat supply water transport commentaries on classics under the few situation of surplus hot water's quantitative change of hot-water cylinder 6 is described.The maximum heating ability Q of refrigerant loop 5 changes according to outside air temperature with from the temperature that hot-water cylinder 6 supplies to the water of refrigerant loop 5.Because the temperature of water and the variation of outside air temperature change simultaneously, so, so can think that maximum heating ability Q changes according to outside air temperature.Shown in Figure 7 is relatively with 45 ℃ of relations of supplying with the maximum heating ability Q of the outer temperature degree under the hot water situation.
In a large amount of occasions of supplying with hot water such as when bathtub 16 is supplied with hot water etc., surplus hot water's quantitative change at hot-water cylinder 6 must be than setting after a little while, according to the output valve of temperature sensor 21 and the output valve of outdoor temperature sensor 26, calculate the maximum heating ability Q of refrigerant loop 5, the value of calculating according to maximum heating ability Q by the delayed heat water yield of hot-water cylinder 6 and refrigerant loop 5, minimizing is from the quantity delivered of the warm water of hot-water cylinder 6, the heating efficiency that makes refrigerant loop 5 increases the quantity delivered from the warm water of water loop 9 for maximum.Have again,, stop to supply with warm water, only supply with warm water from water loop 9 from hot-water cylinder 6 in the few occasion of surplus hot water's quantitative change of hot-water cylinder 6.
For example, following occasion is described: store 80 ℃ hot water at hot-water cylinder 6, the delayed heat water yield be 90 liters, outside air temperature be 2 ℃, running water temperature be 5 ℃, with 18 minutes with 43 ℃ of hot water to 180 liters of bathtub 16 supplies.At this moment, Teat pump boiler is that 45 ℃ maximum heating ability is 8kW according to Fig. 7 in heating-up temperature.Therefore, can supply with 45 ℃ hot water with the flow of 2.87 liters of per minutes.
But the occasion supply with 180 liters 45 ℃ hot water with 18 fens clockwise bathtubs 16 needs per minute to supply with 10 liters of hot water.This moment, needed heat supply outlet capacity was 27.9kW, and only the heating efficiency of refrigerant loop 5 is 19.9kW, scarce capacity.Therefore, supply with 80 ℃ warm water from hot-water cylinder 6 simultaneously, mix, supply with hot water at the running water of the 2nd mixed water valve 14 with 5 ℃.This moment, the heat supply water yield from hot-water cylinder 6 was 3.8 liters of per minutes, and 20 minutes is 76 liters.Consequently, the delayed heat water yield of hot-water cylinder 6 is 24 liters.
At this moment, the delayed heat water yield by surplus hot water's temperature sensor 23 detection hot-water cylinders 6 when the delayed heat water yield is 40 liters, will reduce to 2 liters of per minutes from the heat supply water yield of hot-water cylinder 6, and flow from hot water to bathtub 16 that supply with is 6.6 liters of per minutes.Having, is 30 liters occasion in the delayed heat water yield of hot-water cylinder 6 again, stops to supply with hot water from hot-water cylinder 6, only supplies with hot water from refrigerant loop 5.In this occasion, because the heat supply water yield is 2.87 liters of per minutes, so the needed time of hot water of supplying with 180 liters 45 ℃ to bathtub 16 is 23.9 minutes.But, because the delayed heat water yield is 30 liters, so, supplying with in the process of hot water to bathtub 16, both can supply with hot water (the heat supply water yield is 42 ℃, 15.9 liters, supplies with 80 ℃, 7.9 liters hot water from hot-water cylinder 6) to the kitchen, or after bathtub 16 is supplied with hot water, and then use shower (the heat supply water yield is 42 ℃, 40 liters, supplies with 80 ℃, 19.5 liters hot water from hot-water cylinder 6), also can guarantee enough heat supply water yields.
A kind of small-sized Teat pump boiler can be provided, make it by carrying out above such running, even after bathtub 16 is supplied with hot water in large quantities, also can guarantee the delayed heat water yield that hot-water cylinder 6 is certain, even after bathtub 16 is supplied with hot water, and then supply with the occasion of the hot water of hot water or supply shower to the kitchen, can not only prevent disconnected hot water phenomenon, the flow of enough supply hot water can also be guaranteed, heat supply water load can be dealt with fully.
As previously discussed, in the present embodiment, because according to the output valve of temperature sensor 21 and the output valve of outdoor temperature sensor 26, calculate the maximum heating ability Q of refrigerant loop, in the delayed heat water yield of hot-water cylinder 6 occasion littler than setting, minimizing is from the quantity delivered of the warm water of hot-water cylinder 6, increase is from the quantity delivered of the warm water of water loop 9, be the ratio that the maximum heating ability Q according to the delayed heat water yield of hot-water cylinder 6 and refrigerant loop 5 calculates,, stop to supply with warm water from hot-water cylinder 6 in the fewer occasion of the delayed heat water yield of hot-water cylinder 6, only supply with warm water from water loop 9, therefore, can not produce disconnected hot water phenomenon, can deal with heat supply water load fully.
As previously discussed, because the Teat pump boiler that the present invention relates to, volume is little, can deal with heat supply water load fully, so, can be arranged on narrow and small place, can not only be used for family, also can be used for Teat pump boiler that industry uses etc.
