On the other hand, when being judged to be in the situation of No at step S20, get back to step S19, control device 1a adjusts the valve opening of idle call expansion valve 27 until reach the target condensation temperature (Tc) of Air-conditioning Cycle.Like this, in the processing of control 3 patterns, because the air-conditioning heat dissipation amount is less than hot water supply caloric receptivity, therefore, at first, control so that the little Air-conditioning Cycle of heat reaches target condensation temperature (Tc).Then, when being judged to be at step S21 in the situation of No, in step S22, adjust the aperture of (turning down slightly) the 3rd expansion valve 49a and the 4th expansion valve 49c.Then, get back to step S19, control device 1a adjusts the aperture of the 3rd expansion valve 49a and the 4th expansion valve 49c until reach the target evaporating temperature (Te) of hot water supply circulation.Like this, in the processing of control 3 patterns, the running of control device 1a control hot water supply circulation after Air-conditioning Cycle reaches target condensation temperature (Tc).

At this, the order that is used for making the hot water supply circulation reach the control of target evaporating temperature (Te) is, carry out first the adjustment (step S19) of hot water supply with the rotating speed of outdoor fan 45, under hot water supply even so circulates the situation of also miss the mark evaporating temperature (Te) (be the situation of No at step S21), adjust complementaryly and be positioned at hot water supply with the 3rd expansion valve 49a of the gateway of heat source side heat exchanger 44 and the aperture of the 4th expansion valve 49c.Namely, control device 1a, even at the rotating speed of control hot water supply with outdoor fan 45, hot water supply with the heat exchange amount of heat source side heat exchanger 44 and and the difference quite poor value heat of the hot water supply caloric receptivity of in step S3, trying to achieve and air-conditioning heat dissipation amount between difference also be in the situation beyond the predetermined scope, the aperture of adjusting the 3rd expansion valve 49a and the 4th expansion valve 49d is described poor to compensate, thereby controls to guarantee the balance of heat-shift.

Next, with reference to Fig. 9～Figure 11 cold-producing medium and the mobile of hot pumped (conveying) medium in the scheduling operation mode are described.At first, use Fig. 9 explanation " controlling 1 pattern ".Under control 1 pattern, the first expansion valve 35c, the second expansion valve 35d, the 3rd expansion valve 49a and the 4th expansion valve 49c close, and idle call outdoor fan 25 and hot water supply stop with outdoor fan 45.

In air-conditioning refrigeration agent loop 5, the gas refrigerant of the HTHP of being discharged by the outlet 21b of idle call compressor 21 flows into intermediate heat exchangers 23 by cross valve 22.At the gas refrigerant of the interior mobile HTHP of intermediate heat exchanger 23, to hot water supply condensation with refrigerant loses heat, the liquefaction of the low temperature that flows at intermediate heat exchanger 23.The liquid refrigerant of this high pressure is expanded by idle call expansion valve 27 decompressions that are adjusted to predetermined aperture after flowing to air-conditioning refrigeration agent container 26, becomes the gas-liquid two-phase cold-producing medium of low-temp low-pressure, then flows into idle call and utilizes side heat exchanger 28.Utilize side heat exchanger 28 interior mobile gas-liquid two-phase cold-producing mediums in idle call, from the cold water heat absorption of the interior mobile high temperature of idle call hot and cold water closed circuit 8 and evaporate, become the gas refrigerant of low pressure.The gas refrigerant of this low pressure flows into the suction inlet 21a of idle call compressors 21 by cross valve 22, is again compressed and is become the gas refrigerant of HTHP by idle call compressor 21.

In idle call hot and cold water closed circuit 8, to the cold water that utilizes in idle call after the 28 mobile air-conditioning refrigeration agent of side heat exchanger are dispelled the heat, by driving idle call hot and cold water circulating pump 52, by idle call cold and hot water piping system 55a and inflow indoor heat exchanger 61.In indoor heat converter 61, the cold water in the idle call hot and cold water closed circuit 8 and the air of dwelling house 60 interior high temperature carry out heat exchange, and the air of dwelling house 60 is cooled.That is, freezed in the indoor of dwelling house 60.At this moment, absorb heat and heat up from the air in the dwelling house 60 at cold water that indoor heat converter 61 flows.Cold water after this intensification utilizes idle call hot and cold water circulating pump 52 to flow to idle call cold and hot water piping system 55b, 55c, and again idle call utilize in the process that side heat exchanger 28 flows with in air-conditioning refrigeration agent loop the 5 air-conditioning refrigeration agent of flowing carry out heat exchange and be cooled.

On the other hand, with in the refrigerant loop 6, with compressor 41 compressions become the gas refrigerant of HTHP by hot water supply in hot water supply, the inflow hot water supply is with utilizing side heat exchanger 42.At the gas refrigerant of hot water supply with the interior mobile HTHP of heat source side heat exchanger 42, at hot water supply stream 9 interior mobile water-cooleds and condensation, liquefaction.Then, the cold-producing medium of the high pressure that has liquefied is flowing through hot water supply with behind the cryogen vessel 46, is reduced pressure with expansion valve 43 and is expanded by the hot water supply that is adjusted to predetermined aperture, becomes the gas-liquid two-phase cold-producing medium of low-temp low-pressure.This gas-liquid two-phase cold-producing medium from the air-conditioning refrigeration agent heat absorption of the high temperature that flows at intermediate heat exchanger 23 and evaporate, becomes the gas refrigerant of low pressure in the process that flows through intermediate heat exchanger 23.The gas refrigerant of this low pressure flows into hot water supply with the suction inlet 41a of compressor 41, is again compressed with compressor 41 and is become the gas refrigerant of HTHP by hot water supply.

In hot water supply stream 9, flow into the water of feed water inlet 78, interior mobile and be directed to hot water supply with utilizing side heat exchanger 42 with pipe arrangement 72 in hot water supply.Flow into hot water supply with utilizing the water of side heat exchanger 42, in hot water supply with utilizing side heat exchanger 42 to absorb heat with cold-producing medium and become the hot water of high temperature from the hot water supplies of flowing with refrigerant loop 6 in hot water supply.This hot water flows and is stored by hot water storage container 70 with pipe arrangement 73 is interior in hot water supply, is directed to the hot water supply load-side according to user's requirement from hot water supply mouth 79.

Like this, under control 1 pattern, because hot water supply caloric receptivity and air-conditioning heat dissipation amount are equal, therefore needn't use idle call heat source side heat exchanger 24 and hot water supply heat source side heat exchanger 44, and only use intermediate heat exchanger 23, just can realize carrying out waste heat utilization with Air-conditioning Cycle in the running of the air conditioning hot feed system of hot water supply circulation.Therefore, control 1 pattern according to this, the heat extraction of Air-conditioning Cycle can not wasted, and can realize the efficient activity of entire system.

Then, use Figure 10 explanation " controlling 2 patterns ".Under control 2 patterns, the first expansion valve 35c and the second expansion valve 35d open, and the 3rd expansion valve 49a and the 4th expansion valve 49c close.And, 25 rotations of idle call outdoor fan, and hot water supply stops with outdoor fan 45.

In air-conditioning refrigeration agent loop 5, the gas refrigerant of the HTHP of being discharged by the outlet 21b of idle call compressor 21 flows into intermediate heat exchanger 23 and idle call heat source side heat exchangers 24 by cross valve 22.In hot water supply condensation with refrigerant loses heat, the liquefaction to the low temperature that flows at intermediate heat exchanger 23 of the gas refrigerant of the interior mobile HTHP of intermediate heat exchanger 23, simultaneously, at the gas refrigerant of the interior mobile HTHP of idle call heat source side heat exchanger 24 to the atmosphere heat radiation that transports from idle call outdoor fan 25 and condensation, liquefaction.The liquid refrigerant of this high pressure is expanded by idle call expansion valve 27 decompressions that are adjusted to predetermined aperture after flowing through air-conditioning refrigeration agent container 26, becomes the gas-liquid two-phase cold-producing medium of low-temp low-pressure, then flows into idle call and utilizes side heat exchanger 28.Utilize side heat exchanger 28 interior mobile gas-liquid two-phase cold-producing mediums in idle call, from the cold water heat absorption of the interior mobile high temperature of idle call hot and cold water closed circuit 8 and evaporate, become the gas refrigerant of low pressure.The gas refrigerant of this low pressure flows into the suction inlet 21a of idle call compressors 21 by cross valve 22, is again compressed and is become the gas refrigerant of HTHP by idle call compressor 21.

On the other hand, with in the refrigerant loop 6, the gas refrigerant that is become HTHP by hot water supply with compressor 41 compressions flows into hot water supply with utilizing side heat exchanger 42 in hot water supply.In hot water supply with the gas refrigerant of the interior mobile HTHP of heat source side heat exchanger 42 at hot water supply stream 9 interior mobile water-cooleds and condensation, liquefaction.Then, the liquid refrigerant of the high pressure that has liquefied is flowing through hot water supply with behind the cryogen vessel 46, is reduced pressure with expansion valve 43 and is expanded by the hot water supply that is adjusted to predetermined aperture, becomes the gas-liquid two-phase cold-producing medium of low-temp low-pressure.This gas-liquid two-phase cold-producing medium from the air-conditioning refrigeration agent heat absorption of the high temperature that flows at intermediate heat exchanger 23 and evaporate, becomes the gas refrigerant of low pressure in the process that flows through intermediate heat exchanger 23.The gas refrigerant of this low pressure flows into hot water supply with the suction inlet 41a of compressor 41, and is again compressed with compressor 41 and become the gas refrigerant of HTHP by hot water supply.

In addition, control the idle call hot and cold water closed circuit 8 in 2 patterns cold water flow and hot water supply stream 9 in water flow identical with control 1 pattern, therefore omission explanation herein.

Like this, under control 2 patterns, owing to the air-conditioning heat dissipation amount is supplied with caloric receptivity greatly than hot water, therefore, and the heat radiation from idle call heat source side heat exchanger 24 to atmosphere, the amount of described heat radiation is the poor quite poor value heat that recepts the caloric with air-conditioning heat dissipation amount and hot water supply.At this moment, in the hot water supply circulation, do not use hot water supply heat source side heat exchanger 44.That is, in hot water supply circulation, can be only carry out the running of air conditioning hot feed system that the waste heat utilization of Air-conditioning Cycle is circulated in hot water supply with intermediate heat exchanger 23.Therefore, control 2 patterns according to this, the heat extraction of Air-conditioning Cycle can not wasted, and can realize the efficient activity of entire system.

Then, use Figure 11 explanation " controlling 3 patterns ".Under control 3 patterns, the first expansion valve 35c and the second expansion valve 35d close, and the 3rd expansion valve 49a and the 4th expansion valve 49c open.And idle call outdoor fan 25 stops, and hot water supply is rotated with outdoor fan 45.

In air-conditioning refrigeration agent loop 5, the gas refrigerant of the HTHP of being discharged by the outlet 21b of idle call compressor 21 flows into intermediate heat exchangers 23 by cross valve 22.At the gas refrigerant of the interior mobile HTHP of intermediate heat exchanger 23, to hot water supply condensation with refrigerant loses heat, the liquefaction of the low temperature that flows at intermediate heat exchanger 23.The liquid refrigerant of this high pressure is expanded by idle call expansion valve 27 decompressions that are adjusted to predetermined aperture after flowing through air-conditioning refrigeration agent container 26, becomes the gas-liquid two-phase cold-producing medium of low-temp low-pressure, then flows into idle call and utilizes side heat exchanger 28.Utilize side heat exchanger 28 interior mobile gas-liquid two-phase cold-producing mediums in idle call, from the cold water heat absorption of the interior mobile high temperature of idle call hot and cold water closed circuit 8 and evaporate, become the gas refrigerant of low pressure.The gas refrigerant of this low pressure flows into the suction inlet 21a of idle call compressors 21 by cross valve 22, is again compressed and is become the gas refrigerant of HTHP by idle call compressor 21.

On the other hand, with in the refrigerant loop 6, the gas refrigerant that is become HTHP by hot water supply with compressor 41 compressions flows into hot water supply with utilizing side heat exchanger 42 in hot water supply.At the gas refrigerant of hot water supply with the interior mobile HTHP of heat source side heat exchanger 42, at hot water supply stream 9 interior mobile water-cooleds and condensation, liquefaction.Then, the cold-producing medium of the high pressure that has liquefied is flowing through hot water supply with behind the cryogen vessel 46, is reduced pressure with expansion valve 43 and is expanded by the hot water supply that is adjusted to predetermined aperture, becomes the gas-liquid two-phase cold-producing medium of low-temp low-pressure.This gas-liquid two-phase cold-producing medium is in flowing through intermediate heat exchanger 23 and the hot water supply process with heat source side heat exchanger 44, absorb heat and evaporate from the air-conditioning refrigeration agent of the high temperature that flows at intermediate heat exchanger 23 with by the atmosphere that hot water supply comes with outdoor fan 45 outputs respectively, become the gas refrigerant of low pressure.The gas refrigerant of this low pressure flows into hot water supply with the suction inlet 41a of compressor 41, is again compressed with compressor 41 and is become the gas refrigerant of HTHP by hot water supply.

In addition, control the idle call hot and cold water closed circuit 8 in 3 patterns cold water flow and hot water supply stream 9 in water flow identical with control 1 pattern, therefore omission explanation herein.

Like this, under control 3 patterns, because the hot water supply caloric receptivity is larger than air-conditioning heat dissipation amount, therefore, utilize hot water supply with heat source side heat exchanger 44 from the atmosphere heat absorption, the amount of described heat absorption is the poor quite poor value heat with hot water supply caloric receptivity and air-conditioning heat dissipation amount.At this moment, in Air-conditioning Cycle, do not use idle call heat source side heat exchanger 24.That is, the heat extraction of Air-conditioning Cycle is only passed through intermediate heat exchanger 23 to the hot water supply circulation cooling.In other words, the heat extraction of Air-conditioning Cycle all is used in the hot water supply circulation.Therefore, control 3 patterns according to this, the heat extraction of Air-conditioning Cycle can not wasted, and can realize the efficient activity of entire system.

Then, with reference to Figure 12 cold-producing medium and the mobile of hot pumped (conveying) medium in " forcing the heat run pattern " are explained.Forcing under the heat run pattern, two- port valve 35a, 35b open, and two- port valve 49b, 49d close, and expansion valve 35c, 35d, 49a, 49c open.Therefore, hot water supply does not flow to intermediate heat exchanger 23 with cold-producing medium, uses heat source side heat exchanger 44 and only flow to hot water supply, and the air-conditioning refrigeration agent flows to intermediate heat exchanger 23 and idle call heat source side heat exchanger 24 both sides.

In air-conditioning refrigeration agent loop 5, the gas refrigerant of the HTHP of being discharged by the outlet 21b of idle call compressor 21 flows into idle calls by cross valve 22 and utilizes side heat exchanger 28.Utilize the gas refrigerant of the interior mobile HTHP of side heat exchanger 28 in idle call, to 8 interior mobile hot water heat radiations and condensation in idle call hot and cold water loop, liquefaction.The liquid refrigerant of this high pressure is expanded by idle call expansion valve 27 decompressions that are adjusted to predetermined aperture, become the gas-liquid two-phase cold-producing medium of low-temp low-pressure, then flow into idle call heat source side heat exchanger 24 and intermediate heat exchanger 23 by air-conditioning refrigeration agent container 26.At idle call heat source side heat exchanger 24 interior mobile gas-liquid two-phase cold-producing mediums, from the heat absorption of the atmosphere that transported by idle call outdoor fan 25 and evaporate, thereby become the gas refrigerant of low pressure.On the other hand, at intermediate heat exchanger 23 interior mobile gas-liquid two-phase cold-producing mediums, never the plate that flows through with cold-producing medium of hot water supply absorbs some heats and evaporates, and becomes the gas refrigerant of low pressure.The gas refrigerant of this low pressure flows into the suction inlet 21a of idle call compressors 21 by cross valve 22, is again compressed and is become the gas refrigerant of HTHP by idle call compressor 21.

On the other hand, with in the refrigerant loop 6, with compressor 41 compressions become the gas refrigerant of HTHP by hot water supply in hot water supply, the inflow hot water supply is with utilizing side heat exchanger 42.At the gas refrigerant of hot water supply with the interior mobile HTHP of heat source side heat exchanger 42, at hot water supply stream 9 interior mobile water-cooleds and condensation, liquefaction.Then, the liquid refrigerant of the high pressure that has liquefied is flowing through hot water supply with behind the cryogen vessel 46, is reduced pressure with expansion valve 43 and is expanded by the hot water supply that is adjusted to predetermined aperture, becomes the gas-liquid two-phase cold-producing medium of low-temp low-pressure.This gas-liquid two-phase cold-producing medium flow through hot water supply with the process of heat source side heat exchanger 44 in from the atmosphere heat absorption that transported with outdoor fan 45 by hot water supply and evaporate, thereby become the gas refrigerant of low pressure.Then, the gas refrigerant of the low pressure that flows out with heat source side heat exchanger 44 from hot water supply flows into hot water supply with the suction inlet 41a of compressor 41, is again compressed with compressor 41 and is become the gas refrigerant of HTHP by hot water supply.

In addition, flowing of the hot water in the air-conditioning refrigeration agent loop 8 is identical with " heating/hot water supply individual operation pattern ", therefore omits explanation herein.And flowing of the water in the hot water supply stream 9 is identical with " cooling/heating water is supplied with the individual operation pattern ", therefore omits explanation herein.

At this, forcing the key character of heat run pattern is not have hot water supply to use as evaporimeter in Air-conditioning Cycle with the intermediate heat exchanger 23 that cold-producing medium flows through.That is, being characterized as of this pattern also absorbed heat from the thermal conductive surface of hollow plate, thereby also improved slightly the ability that heats running in air-conditioning refrigeration agent loop 5.Therefore, in the indoor situation that is difficult to fully heat of dwelling house 60, the running of carrying out this pressure heat run pattern is effective in the winter time.

Then, control in mobile and this operation mode of cold-producing medium and hot pumped (conveying) medium in " moment boiling operation mode " is described, flowing for cold-producing medium and hot pumped (conveying) medium but, because identical with scheduling operation mode " controlling 3 patterns " (with reference to Figure 11), therefore omit explanation herein, only the control of moment boiling operation mode described with Figure 13 and Figure 14.

When moment boiling operation mode began, at first, in step S101, but control device 1a judged that the vessel temp inputted from temperature sensor TH21 is whether below the temperature as supplying hot water.When being in the situation of Yes at step S101, control device 1a judges in step S102 whether the hot water supply caloric receptivity is larger than air-conditioning heat dissipation amount.In the hot water supply caloric receptivity situation larger than air-conditioning heat dissipation amount, advance to step S103, control device 1a opens two-port valve 35a, 35b, 49b, the 49d of the gateway of intermediate heat exchanger 23, open and be positioned at the 3rd expansion valve 49a and the 4th expansion valve 49c that the gateway of heat source side heat exchanger 44 is used in hot water supply, the first expansion valve 35c and the second expansion valve 35d that close the gateway that is positioned at idle call heat source side heat exchanger 24.Namely, because the hot water supply caloric receptivity is larger than air-conditioning heat dissipation amount, therefore, control device 1a becomes can be while utilizing hot water supply carry out the state that cooling operation and hot water supply are turned round with heat source side heat exchanger 44 from atmosphere heat absorption, and the amount of described heat absorption is the poor quite poor value heat with hot water supply caloric receptivity and air-conditioning heat dissipation amount.

Next, advance to step S104, control device 1a carries out the reception ﹠ disposal of various data.Specifically, control device 1a receives target hot water amount, target hot water temperature, running water temperature (from the input of temperature sensor TH1), the outdoor temperature (from the input of temperature sensor TH19) in the hot water supply circulation.And then control device 1a receives target temperature, target air quantity, indoor temperature (from the input of temperature sensor TH20), the outdoor temperature (from the input of temperature sensor TH19) in the Air-conditioning Cycle.Then, advance to step S105, control device 1a calculates the target capability of Air-conditioning Cycle, the rotating speed of idle call compressor 21, the rotating speed of idle call outdoor fan 25, the discharge temperature of idle call compressor 21, power consumption and the heat dissipation capacity of idle call compressor 21 based on the various data that receive in step S104.

Next, advance to step S106, control device 1a is received in the data of the heat dissipation capacity of the Air-conditioning Cycle that calculates among the step S105, and receives the data of target hot water amount in the hot water supply circulation, target hot water temperature, running water temperature, outdoor temperature.Then, advance to following step S107, the target capability of control device 1a calculating hot water supply circulation, the rotating speed that compressor 41 is used in hot water supply, the rotating speed that outdoor fan 45 is used in hot water supply, the power consumption that hot water supply is used compressor 21 with discharge temperature and the hot water supply of compressor 41.Next, advance to step S108, control device 1a controls the running of hot water supply circulation and Air-conditioning Cycle according to the result of calculation that has just obtained.

Specifically, control device 1a in hot water supply circulation the control hot water supply with compressor 41 to reach rotating speed of target, the control hot water supply with the rotating speed of outdoor fan 45 reaching rotating speed of target, and control hot water supply with the valve opening of expansion valve 43 to reach target capability.And control device 1a controls idle call compressor 21 to reach rotating speed of target in Air-conditioning Cycle, stop idle call outdoor fan 25, and the valve opening of control idle call expansion valve 27 is to reach target capability.

Next, advance to step S109, control device 1a judges whether hot water supply circulation and Air-conditioning Cycle reach respectively target capability.When in step S109, being judged to be in the situation of Yes, advance to step S110, control device 1a determines whether to reach and need to carry out hot water supply and add water.Add at needs in the situation of water, advance to step S111, control device 1a closing containers return valve (not shown), the return valve of fetching boiling water (not shown) Lai Jiashui.On the other hand, be in the situation of No at step S110, advance to step S112, control device 1a closing containers return valve (not shown) cuts out water loop valve (not shown).That is, do not add water.Then, in step S113, via the tap supplying hot water of hot water supply mouth 79 from hot water supply load-side (not shown).Then, in next step, return, skip the processing of moment boiling operation mode.In addition, when being in the situation of No, get back to step S108 in step S109, in the situation that in step S101, is judged to be No and in step S102, be judged to be in the situation of No, return and skip the processing of moment boiling operation mode.
