More specifically, the unnecessary cold-producing medium that liquid reservoir 248 is preserved from outdoor unit 100, and only make liquid refrigerant flow.That is to say that under " utilizing the room refrigerating mode of accumulation of heat ", liquid reservoir 248 only makes liquid refrigerant flow in thermal storage unit 300.

The 4th valve 226 has an end to be connected to high pressure accumulation of heat joint 250.High pressure accumulation of heat joint 250 has an end of coupled thermal storage unit 300 pipelines.

In functional element 200, on the pipeline between the 3rd valve 224 and the 4th valve 226, the 5th valve 252 is installed.The 5th valve 252 has coupled indoor high-pressure flow pipeline 410, and it is connected with the following indoor unit that will describe 400.

Functional element 200 is connected with indoor unit 400 with indoor low pressure flow line 412 by indoor high-pressure flow pipeline 410.Functional element 200 has indoor high pressure connection 262 and indoor low-pressure connector 260, and it is connected with indoor low pressure flow line 4 12 with indoor high-pressure flow pipeline 410 respectively.

On an end of indoor low-pressure connector 260, stop valve 270 is installed, is used for optionally being breaking at the flow of refrigerant between indoor unit 400 and the functional element 200.

Functional element 200 receives from the flow through cold-producing medium of low pressure accumulation of heat joint 272 of thermal storage unit 300, and low pressure accumulation of heat joint 272 is connected with second valve 218.

Thermal storage unit 300 is connected with functional element 200, and the flow of refrigerant between thermal storage unit 300 and functional element 200 is by

second valve

218 and 226 controls of the 4th valve.

In thermal storage unit 300, be provided with heat storage container 310, be used to preserve heat storage material.Therefore, because heat storage material is heated or cooled, heat is stored in the heat storage container 310.Heat storage material storage power in heat storage container 310, and preferably have hyperbaric H2O.

In heat storage container 310, accumulation of heat heat exchanger 320 is arranged.Be provided with two accumulation of heat heat exchangers 320 therein, be used for the cold-producing medium of portion within it and between the heat storage material in heat storage container 310 outsides, carry out heat exchange.That is to say that accumulation of heat heat exchanger 320 comprises the first accumulation of heat heat exchanger 322 and the second accumulation of heat heat exchanger 324, heat or cool off heat storage material in the heat storage container 310 with temperature according to cold-producing medium in the accumulation of heat heat exchanger 320.

Side at the first accumulation of heat heat exchanger 322 is equipped with the first accumulation of heat expansion gear 330, and in a side of the second accumulation of heat heat exchanger 324 the second accumulation of heat expansion gear 332 is installed.The first accumulation of heat expansion gear 330 and the second accumulation of heat expansion gear 332 control flow to the flow of refrigerant speed in the thermal storage unit 300, and make cold-producing medium expand into low temperature and low pressure.

As the first accumulation of heat expansion gear 330 and the second accumulation of heat expansion gear 332, the valve of many types can adopt, and for example is known as electric expansion valve, magnetic valve of LEV (linear expansion valve) or the like.

Therefore, under the accumulation of heat pattern, the first accumulation of heat expansion gear 330 and the second accumulation of heat expansion gear 332 will with the temperature and pressure of reduction cold-producing medium, and impel the flow rate of cold-producing medium and the load of accumulation of heat heat exchanger 320 to adapt in outdoor heat converter 120 condensed refrigerant adiabatic expansions.

Preferably, the aperture of the first accumulation of heat expansion gear 330 and the second accumulation of heat expansion gear, 332 control valves is compressed the flow rate of cold-producing medium with effective adjusting.

Indoor unit 400 comprises the indoor heat converter that is used to carry out heat exchange, and the indoor expansion gear 430 that is used for swell refrigeration agent and control flow of refrigerant speed.

One or two indoor unit 400 is arranged, and its capacity is suitable for cooling off or the space of heat rooms.

Similar with the first accumulation of heat expansion gear 330 and the second accumulation of heat expansion gear 332, indoor expansion gear 430 is LEV.Therefore, under " the direct refrigerating mode in room ", indoor expansion gear 430 will be in outdoor heat converter 120 the condensed refrigerant adiabatic expansion, reducing the temperature and pressure of cold-producing medium, and impel the flow rate of cold-producing medium and the load of indoor heat converter 420 to adapt.

To be example with the situation of cool room below, the operation of heat-storing air conditioner will be described.

At first, with reference to Fig. 4, heat-storing air conditioner of the present utility model operates under " accumulation of heat pattern ".

Under " accumulation of heat pattern ", will night promptly energy consume low during storage power in thermal storage unit 300 in advance, more particularly, will change the state of heat storage material (if heat storage material is a water, become ice), heat storage material is kept in the heat storage container 310 of thermal storage unit 300.

In this case, operation outdoor unit 100, functional element 200 and thermal storage unit 300.That is to say that functional element 200 makes outdoor unit 100 and thermal storage unit 300 communicate with each other, and cut off cold-producing medium flowing to indoor unit 400.

More specifically, the cold-producing medium indoor low pressure flow line 412 of flowing through, and indoor high-pressure flow pipeline 410 is cut off valve 270 and the 5th valve 252 cuts off, to stop cold-producing medium flowing between indoor unit 400 and functional element 200.

First valve 216 and second valve 218 have stoped flowing of the cold-producing medium that is imported into additional flow pipeline 210.The 3rd valve 224 and the 4th valve 226 cut off liquid flow pipeline 240.

Therefore, as shown by arrows, cold-producing medium is compressed to high pressure by compressor 110, and imports in the outdoor heat converter 120 by cross valve 140.

Usually, because outdoor heat converter 120 is installed in the outside of building, the cold-producing medium and the building air outside of outdoor heat converter 120 inside of therefore flowing through are carried out heat exchange.

Owing to be " accumulation of heat pattern ", therefore the cold-producing medium in outdoor heat converter 120 is to building air outside discharges heat.That is to say that because outdoor heat converter 120 is as condenser, so cold-producing medium is cooled by carrying out heat exchange with the building air outside, thereby become liquid refrigerant (certainly, be not liquid refrigerant) completely.

Then, cold-producing medium is discharged from outdoor heat converter unit 120, the outdoor expansion gear 150 of flowing through, and be imported in the functional element 200.

Then, cold-producing medium is imported in the thermal storage unit 300.That is to say that owing to liquid flow pipeline 240 is cut off by the 3rd valve 224 and the 4th valve 226, so the cold-producing medium in the import feature unit 200 imports in the thermal storage unit 300 by high pressure accumulation of heat joint 250 is directly mobile.

The cold-producing medium that imports thermal storage unit 300 is divided into two-way, and flow through the respectively first accumulation of heat expansion gear 330 and the second accumulation of heat expansion gear 332.The cold-producing medium of the first accumulation of heat expansion gear 330 and the second accumulation of heat expansion gear 332 of flowing through becomes the cold-producing medium of relative low temperature, low pressure by expansion, more preferably, becomes temperature at sub-zero cold-producing medium.

When cold-producing medium is flowed through the first accumulation of heat heat exchanger 322 and the second accumulation of heat heat exchanger 324, the cold-producing medium generation heat exchange of the flow through first accumulation of heat expansion gear 330 and the second accumulation of heat expansion gear 332.In this case, the first accumulation of heat heat exchanger 322 and the second accumulation of heat heat exchanger 324 are kept at the temperature of heat storage material in the heat storage container 310 with reduction, thereby change the state (freezing) of heat storage material in the heat storage container 310 at last as evaporimeter.That is to say that the temperature of heat storage material reduces in the heat storage container 310, have the state (freezing) that begins to change gradually from accumulation of heat heat exchanger 320 on every side.

When cold-producing medium was flowed through accumulation of heat heat exchanger 320, the cold-producing medium that has absorbed heat flashed to gas, and by in the low pressure accumulation of heat joint 272 import feature unit 200.Because second valve 21 8 and first valve 216 have cut off the flow line of guiding to additional flow pipeline 210, import to cold-producing medium in the functional element 200 additional flow pipeline 210 of can not flowing through, but import in the outdoor unit 100 through functional low-pressure connector 220 and outdoor low-pressure connector 160.The cold-producing medium that imports in the outdoor unit 100 is directed in the reservoir 130 by cross valve 140.

Reservoir 130 filters out liquid refrigerant, only gaseous refrigerant is imported in the compressor 110.

According to above-mentioned steps, the circulation of " accumulation of heat pattern " has been finished, and under " accumulation of heat pattern ", phase transformation (if heat storage material is a water, becoming ice so) has taken place in the heat storage container 310 of thermal storage unit 300.

Fig. 5 shows the flow of refrigerant under " utilizing accumulation of heat cool room pattern ".That is to say, show the process of cool room by utilizing energy stored, this energy utilizes above-mentioned " accumulation of heat pattern " and store.

" utilize accumulation of heat cool room pattern " and mainly use on daytime when the energy consume significant, with by utilize night energy stored come cool room.

In this case, cold-producing medium flow through functional element 200, thermal storage unit 300 and indoor unit 400, and stop at outdoor unit 100.That is to say, be cut off, allow flow of refrigerant in additional flow pipeline 210 and liquid flow pipeline 240 by first valve 216 and the 3rd valve 224 to the flow of refrigerant of outdoor unit 100.In this case, second valve 218 has cut off the flow line that links to each other with first valve 216, and opens the flow line that imports additional flow pipeline 210 and low pressure accumulation of heat joint 272.The 4th valve 226 has cut off the flow line that links to each other with the 5th valve 252, and opens the flow line that imports liquid flow pipeline 240 and high pressure accumulation of heat joint 250.The 5th valve 252 is opened the flow line that imports indoor high-pressure flow pipeline 410, and has cut off the flow line that links to each other with the 4th valve 226.

At first, cold-producing medium by high pressure accumulation of heat joint 250 import feature unit 200 will be described.

In this case, owing to open liquid flow pipeline 240 by the 3rd valve 224 and the 4th valve 226, therefore the cold-producing medium from thermal storage unit 300 import feature unit 200 flows through liquid flow pipeline 240.

The cold-producing medium of liquid flow pipeline 240 of flowing through is forced mobile by liquid pump 246.Therefore, comprise moisture in the cold-producing medium of the liquid flow pipeline 240 of flowing through, and when cold-producing medium was flowed through liquid reservoir 248 and liquid pump 246, gas refrigerant was wherein removed therefrom.

More specifically, liquid reservoir 248 is removed gas refrigerant, and drier 244 is removed moisture from cold-producing medium.

Therefore, the liquid refrigerant of the liquid flow pipeline 240 of flowing through flow through successively second cross valve 242, the 3rd valve 224 and the 5th valve 252, and import in the indoor unit 400 by indoor high pressure connection 262.

Because a plurality of indoor units 400 are arranged, therefore the cold-producing medium that provides from functional element 200 is distributed to indoor unit 400 fifty-fifty.The cold-producing medium that imports indoor unit 400 flows through a plurality of indoor expansion gears 430 respectively.

The cold-producing medium of indoor expansion gear 430 of flowing through becomes and has low pressure, and is imported into indoor heat converter 420, and carries out heat exchange in indoor heat converter 420.That is to say that heat exchange occurs between the cold-producing medium and the air in the room of indoor heat converter 420 inside of flowing through, and when indoor heat converter 420 was used as evaporimeter, cold-producing medium is draw heat from space air.

Like this, when cold-producing medium was flowed through indoor heat converter 420, cold-producing medium evaporation became gaseous state, and space air is by draw heat therefrom, with cool room.

By means of indoor low pressure flow line, be imported into functional element 200 from the cold-producing medium of indoor heat converter 420 through indoor low-pressure connector 260.In this case, the flow through cold-producing medium of stop valve 270 is directed in the additional flow pipeline 210 by first valve 216.By means of complementary pump 214, the cold-producing medium that imports in the additional flow pipeline 210 is compelled to flow in the additional heat exchanger 212.

Additional heat exchanger 212 is undersized heat exchangers, as condenser.Therefore, the flow through cold-producing medium of additional heat exchanger 212 has the temperature that is reduced by additional heat exchanger 212.

The cold-producing medium of additional heat exchanger 212 of flowing through flows through second valve 218 and low pressure accumulation of heat joint 272 successively, and is imported in the thermal storage unit 300.The cold-producing medium that imports in the thermal storage unit 300 flows through accumulation of heat heat exchanger 320.

Heat exchange takes place in accumulation of heat heat exchanger 320.That is to say that heat exchange occurs between the cold-producing medium and the heat storage material (ice) in the heat storage container 310 in the accumulation of heat heat exchanger 320.Therefore, the cold-producing medium draw heat of the heat storage material in the heat storage container 310 (ice) from accumulation of heat heat exchanger 320, and melted, by this process, the cold-producing medium of accumulation of heat heat exchanger 320 inside of flowing through becomes low-temperature refrigerant.

The cold-producing medium of discharging from accumulation of heat heat exchanger 320 is by in high pressure accumulation of heat joint 250 quilts import feature unit again.

According to above-mentioned steps, the circulation of " utilizing accumulation of heat cool room pattern " has been finished, with cool room.

Fig. 6 shows " the direct refrigerating mode in room ", and wherein the room is cooled, and is not to utilize thermal storage unit 300, but directly utilizes outdoor unit 100.

In direct refrigerating mode, stop valve 270 is opened, and first valve 216 and second valve 218 have cut off the flow line of guiding additional flow pipeline 210.The 3rd valve 224 and the 4th valve 226 have cut off the flow line of guiding liquid flow pipeline 240.The 5th valve 252 has cut off the flow line that is connected with the 4th valve 226, and has opened the flow line that is connected with indoor high pressure connection 410.

In case allow compressor 110 put into operation, be imported in the outdoor heat converter 120 by cross valve 140 from the high-pressure refrigerant of compressor 110.Because outdoor heat converter 120 is as condenser, so outdoor air absorbs heat from cold-producing medium, so that cold-producing medium becomes the low temperature liquid cold-producing medium.

The cold-producing medium that the flows through outdoor heat converter 120 outdoor expansion gear 150 of flowing through, and be imported in the functional element 200.The cold-producing medium that is imported in the functional element 200 flows through the 3rd valve 224, the 5th valve 252 and indoor high pressure connection 262 successively, and directly is imported in the indoor unit 400.That is, the flow of refrigerant to thermal storage unit 300 is cut off.

Like this, when cold-producing medium was flowed through indoor heat converter 420, cold-producing medium evaporation became gaseous state, and from space air draw heat, with cool room.These are identical with the method for operation of indoor unit 400 in above-described " utilizing accumulation of heat cool room pattern ".

In this case, because stop valve 270 is opened, and first valve 216 has cut off the flow of refrigerant of additional flow pipeline 210, and therefore the cold-producing medium that imports in the functional element 200 is directed in the outdoor unit 100 by functional low-pressure connector 220 and outdoor low-pressure connector 160.

The cold-producing medium that imports in the outdoor unit 100 is directed in the reservoir 130 by cross valve 140.Reservoir 130 has the liquid refrigerant that leaches from cold-producing medium, only gaseous refrigerant is imported in the compressor 110.

According to above-mentioned steps, " the direct refrigerating mode in room " finished.

1. and 2. be illustrated respectively in before the compressor and state afterwards, and 3. and 4. be illustrated respectively in as the import of the outdoor heat converter 120 of condenser and the state in exit.That is, the pressure of cold-producing medium rises in compressor 110, and in the process that heat exchange takes place, pressure does not change in outdoor heat converter 120, but because temperature change has the change of enthalpy h.

5. symbol represents to import to the state of cold-producing medium in the

functional element

200, and 6. and 7. is illustrated respectively in before the accumulation of heat heat exchanger 320 and the state of cold-producing medium afterwards.

More specifically, when cold-producing medium is flowed through indoor thermal expansion equipment 430 (5. → 6.), cold-producing medium generation pressure reduces.In being used as the accumulation of heat heat exchanger 320 of evaporimeter, pressure does not change, and the temperature owing to cold-producing medium in this process raises, so enthalpy h increase.8. unaccounted symbol represents to import from functional element 200 state of the cold-producing medium the outdoor unit 100.

That is, the heat-storing air conditioner of this embodiment provides such advantage, under the direct refrigerating mode of accumulation of heat pattern and room, realizes heat rooms by additionally utilizing room heating indoor unit 400b.

Simultaneously, Figure 14 to 16 shows the heat-storing air conditioner according to the utility model the 5th preferred embodiment separately.

Heat-storing air conditioner according to the utility model the 5th preferred embodiment designs like this, and the heat storage material (for example water) that is kept in the thermal storage unit 300 can cycle through indoor unit 400, to realize the room cooling by cold-producing medium circulation or cold water circulation.

To be described in more detail this.

With reference to Figure 14, come out from indoor low pressure flow line 4 12 branches with the inner water supply flow lines 340 that are connected of thermal storage unit 300, cold-producing medium flow to functional element 200 by indoor low pressure flow line 412 from indoor unit 400; And the drain flow pipeline 350 that is connected with thermal storage unit 300 comes out from indoor high-pressure flow pipeline 410 branches, and indoor high-pressure flow pipeline 410 is connected between functional element 200 and the indoor unit 400.

Junction at water supply flow line 340 and indoor low pressure flow line 412 is equipped with water supply valve 342, is used for opening/closing water supply flow line 340 and indoor low pressure flow line 412.Junction at drain flow pipeline and indoor pressure duct 410 is equipped with water discharging valve 352, is used for optionally opening/closing drain flow pipeline 350 and indoor high-pressure flow pipeline 410.

On an end of water supply flow line 340, spray spout 344 is arranged, be used to spray the heat storage material (water) that is included in heat storage container 310 inside.Therefore, the heat storage material (water) that will import in the heat storage container 310 by such spray spout 344 sprays in the heat storage container 310, and is cooled off by air.

Circulating pump 354 is installed on drain flow pipeline 350.Circulating pump 354 forces heat storage material (water) to be recycled to indoor unit 400 from heat storage container 310.Promptly, the heat storage material (water) of discharging from thermal storage unit 300 by circulating pump 354 offers indoor unit 400 through indoor high-pressure flow pipeline 410, and import in the thermal storage unit 300 by water supply flow line 340 once more, indoor high-pressure flow pipeline will be explained below.

With reference to Figure 15, in the heat storage container 310 of thermal storage unit 300, water is saved to certain altitude, and water 360 is heat storage materials.Accumulation of heat heat exchanger 320 in the heat storage container 310 is fixed on the fixture 362, and fixture 362 is arranged to across accumulation of heat heat exchanger 320.

Simultaneously, demixing plate 370 is arranged in heat storage container 310, be used for heat storage container 310 being separated in/following direction.Heat storage material in the demixing plate 370 prevention heat storage containers 310 for example water 360 up/down flows, to impel layering.

More specifically, in heat storage container 310, between the water of the water of upside and downside, there is temperature difference.That is, at the upside glassware for drinking water higher temperature (about 7～8 ℃ or 10～15 ℃) is arranged, and lower temperature (about 4～5 ℃) is arranged at the downside glassware for drinking water.Therefore, demixing plate 370 makes the water 360 of upside and downside have the temperature that differs from one another, and to form layer, is used to discharge and is positioned at the water 360 that demixing plate 370 downsides have lower temperature.

Demixing plate 370 has a plurality of small through hole 372, and the water 360 in the heat storage container 310 can pass through this through hole.That is, preferably, demixing plate 370 has the shape of mesh, is used for making the water 360 of heat storage container 310 slowly to pass through.

EGR 380 is arranged in heat storage container 310, be used for forcing water 360 circulations of heat storage container 310.That is, as shown, in the bottom of heat storage container 310 or a plurality of EGRs 380 are arranged, be used to force upwards/down circulation of water 360 on demixing plate 370.

EGR 380 comprises fan and motor etc., is used under the situation that heat storage material (water) at heat storage container 310 do not cycle through indoor unit 400 (under the situation of so-called " cold-producing medium circulation ") and moves.Promptly, heat storage material in heat storage container 310 (water) cycles through (under the situation of so-called " cold water circulation ") under the situation of indoor unit 400, do not use EGR 380, but only in accumulation of heat heat exchanger 320 cold-producing medium cycle through under the situation of indoor unit 400 inside (under the situation of " cold-producing medium circulation "), just use EGR 380.

Drainpipe 390 is connected on the end of heat storage container 310 downsides.Drainpipe 390 is set for when the heat storage material of wanting to change in the heat storage container 310 (water), and heat storage material (water) is discharged to heat storage container 310 outsides.Water discharging valve 392 is installed on drainpipe 390, is used for opening/closing drainpipe 390.

The heat-storing air conditioner of the 5th embodiment has following running.

In the accumulation of heat pattern, utilize under the direct refrigerating mode of accumulation of heat cool room pattern and room, water supply valve 342 and water discharging valve 352 cuts off water supply flow line 340 and drain flow pipelines 350.Therefore, the accumulation of heat pattern of this preferred embodiment air-conditioner, utilize the operation of accumulation of heat cool room pattern and the direct refrigerating mode in room identical with the operation of the utility model first embodiment air-conditioner.

Water supply valve 342 and water discharging valve 352 are opened water supply flow line 340 and drain flow pipeline 350 respectively, are used for the heat storage material of circulation thermal storage unit 300 under " cold water circulation pattern ", for example cold water.

Will be described in greater detail in the state of cold-producing medium under " cold water circulation pattern " and cold water (heat storage material) circulation below with reference to Figure 16.

Under the cold water circulation pattern, all valves all move, so that outdoor unit 100 and thermal storage unit 300 communicate with functional element 200, and cold-producing medium is cut off to the mobile of indoor unit.

That is, stop valve 270 is closed, and first valve 216 and second valve 218 cut off and lead to the flow line of additional flow pipeline 210, and open other flow lines.The 3rd valve 224 and the 4th valve 226 have cut off the flow line of liquid flow pipeline 240, and open other flow lines.The 5th valve 252 cuts off the flow line that is connected to indoor high-pressure flow pipeline 410.In view of the above, between indoor unit 400 and functional element 200, there is not flow of refrigerant.

Water supply valve 342 and water discharging valve 352 are cut to the flow line of functional element 200, and are opened to the flow line of water supply flow line 340 and drain flow pipeline 350 respectively.

As shown by arrows, in this state, in case make compressor 110 operations, cold-producing medium is compressed to high pressure, and imports in the outdoor heat converter 120 by cross valve 140.The outer air of cold-producing medium in the outdoor heat converter 120 and building carries out heat exchange, is cooled into liquid refrigerant (cold-producing medium be not liquid refrigerant) certainly, completely.

Cold-producing medium from outdoor heat converter 120 passes through outdoor expansion gear 150, and is directed in the functional element 200.The cold-producing medium that imports in the functional element 200 is directed in the thermal storage unit 300 by the 3rd valve 224, the 5th valve 252 and the 4th valve 226.

The flow of refrigerant that is directed in the thermal storage unit 300 is divided into two-way, and flow through the respectively first accumulation of heat expansion gear 330 and the second accumulation of heat expansion gear 332.The cold-producing medium of the first accumulation of heat expansion gear 330 and the second accumulation of heat expansion gear 332 of flowing through becomes relatively low pressure, low temperature by expansion, more preferably becomes to be positioned at sub-zero cold-producing medium.

When cold-producing medium is flowed through the first accumulation of heat heat exchanger 322 and the second accumulation of heat heat exchanger 324, flow through the cold-producing medium generation heat exchange of the first accumulation of heat expansion gear 330 and the second accumulation of heat expansion gear 332.In this case, the first accumulation of heat heat exchanger 322 and the second accumulation of heat heat exchanger 324 are kept at the temperature of heat storage material in the heat storage container 310 as evaporimeter with reduction.

When cold-producing medium was flowed through accumulation of heat heat exchanger 320, the cold-producing medium of having drawn heat flashed to gas, and imported in the functional element 200 by low pressure accumulation of heat joint 272.

The cold-producing medium that imports in the functional element 200 imports in the outdoor unit 100 by functional low-pressure connector 220 and outdoor low-pressure connector 160.The cold-producing medium that imports in the outdoor unit 100 is imported in the reservoir 130 by cross valve 140, and is directed to once more in the compressor 110, thereby keeps circulation.

Simultaneously, when the cold-producing medium circular flow is crossed outdoor unit 100, functional element 200, thermal storage unit 300 and circulating pump 354 operations, so that water 360 is recycled to the indoor unit 400 from heat storage container 310, wherein water 360 is heat storage materials.When circulating pump 354 operation, the water 360 that is arranged in heat storage container 310 downsides and has a relatively lower temp imports to indoor high-pressure flow pipeline 410 by drain flow pipeline 350.

In this case, because water discharging valve 352 has cut off the passage of functional element 200, the water 360 that flows through drain flow pipeline 350 is directed in the indoor unit 400 by indoor high-pressure flow pipeline 410.

Because a plurality of indoor units 400 are arranged, be assigned in each indoor unit 400 from the water 360 of heat storage container 310.Import to water 360 in each indoor unit 400 each indoor expansion gear 430 of flowing through respectively.

The water 360 that flows through indoor expansion gear 430 becomes and has low pressure, and is directed in the indoor heat converter 420, and in indoor heat converter 420 heat exchange takes place.That is, heat exchange occurs between the water 360 and the air in the room that flows in the indoor heat converter 420, and when indoor heat converter 420 is used as evaporimeter, water 360 draw heat from space air.

Like this, when water 360 was flowed through indoor heat converter 420, the temperature of water 360 raise, and from space air draw heat, with cool room.

The water 360 of discharging from the indoor heat converter 420 indoor low pressure flow line 412 of flowing through.In this case, owing to cut off by water supply valve 342 to the passage of functional element 200, the water 360 that therefore is directed to the indoor low pressure flow line 412 of flowing through is imported in the water supply flow line 340 of thermal storage unit 300.

The water 360 that flows through water supply flow line 340 sprays the heat storage container 310 from spray spout 344.Accumulate heat storage container 310 from the water 360 of spray spout 344 ejections, and flow downward gradually.In this course, the water 360 in the heat storage container 310 carries out heat exchange in accumulation of heat heat exchanger 320.That is, heat exchange occurs between the cold-producing medium of the water 360 in the heat storage container 310 and the accumulation of heat heat exchanger 320 of flowing through.

Therefore, water 360 temperature in the heat storage container 310 reduce, move down gradually, and by demixing plate 370 (seeing Figure 15).That is, water 360 flows through the small through hole 372 in the demixing plate 370, and moves to demixing plate 370 belows.The cold water 360 that moves to demixing plate 370 belows is imported in the drain flow pipeline 350 once more.According to this process, finished once circulation.

If want to change the water 360 in the heat storage container, open water discharging valve 392, water 360 is discharged to outside the heat storage container 310 by drainpipe 390.

Fig. 17 shows the schematic diagram according to the heat-storing air conditioner of the utility model the 6th preferred embodiment.Heat-storing air conditioner also additionally had cool-heat-exchanger 122, and it is arranged on the outlet side of outdoor heat converter 120 as supercooling apparatus, is used for further cooling refrigeration agent, thereby further improves heat exchange property.

Similar with outdoor heat converter 120, cross cool-heat-exchanger 122 and be used between cold-producing medium and surrounding air, carrying out heat exchange, be used in particular for when cool room, the cold-producing medium that will cool off in outdoor heat converter 120 cools off once more.

At the outlet side of crossing cool-heat-exchanger 122 outdoor expansion gear 150 is installed, is used to control the flow of refrigerant speed that flows through outdoor heat converter 120.When indoor unit 400 heat rooms, outdoor expansion gear 150 expands cold-producing medium.

Outlet side at outdoor expansion gear 150 also is equipped with outdoor liquid reservoir 152.Outdoor liquid reservoir 152 separates liquid refrigerant and gas refrigerant.That is, outdoor liquid reservoir 152 will flow through outdoor heat converter 120 in the outdoor unit 100 and the cold-producing medium of outdoor expansion gear 150 is separated into gas refrigerant and liquid refrigerant, and make gas refrigerant turn back to the inlet side of outdoor heat converter 120.

Therefore, between outdoor liquid reservoir 152 and outdoor heat converter 120 imports, bypass flow pipeline 154 is arranged, be used for flowing of gas refrigerant.

Like this, by through outdoor heat converter 120 with cross cool-heat-exchanger 122 twice condensating refrigerant, the heat exchange rate of outdoor unit 100 has improved, to improve the coefficient of performance of in cool room or heat rooms refrigeration machine or heat pump.

In addition, owing to be separated into gas refrigerant and liquid refrigerant by outdoor liquid reservoir 152 cold-producing mediums, and gas refrigerant turns back to the inlet side of outdoor heat converter 120 again, and therefore the cold-producing medium that imports in thermal storage unit 300 or the indoor unit 400 has become liquid refrigerant completely.Therefore, compare with the common situation when mix refrigerant (gas+liquid) offers thermal storage unit 300 or indoor unit 400, the preferred embodiment of the application has advantage, because heat transfer rate has been enhanced.

Figure 18 to 20 shows the heat-storing air conditioner according to the utility model the 7th preferred embodiment separately, also comprises the supercooling apparatus 170 that is positioned at outdoor heat converter 120 outlet sides.Similar with outdoor heat converter 120, supercooling apparatus 170 makes and carries out heat exchange between cold-producing medium and the surrounding air, cools off once more with the cold-producing medium that will cool off in outdoor heat converter 120, particularly under the direct refrigerating mode of accumulation of heat pattern and room.

The cold-producing medium that supercooling apparatus 170 comprises the two-tube subcooler 172 that is used for carrying out heat exchange, be used for a part is flow through outdoor heat converter 120 imports to the reverse stream pipe 174 of subcooler 172, and is used for and will imports the cold expansion valve 176 of mistake that the cold-producing medium of subcoolers 172 expands by reverse stream pipe 174.

With reference to Figure 19 and 20, cylindrical two-tube subcooler 172 both directed flow is crossed the cold-producing medium of outdoor heat converter 120, and the also cold-producing medium that in the opposite direction flows of guiding is to cause the heat exchange in inner/outer.

More specifically, subcooler 172 comprises the interior pipe 172a of the flow of refrigerant that is used to flow through outdoor heat converter 120, and the outer tube 172b of the cold-producing medium that is used to guide adverse current to flow through reverse stream pipe 174.That is, interior pipe 172a has identical size and dimension with the refrigerant pipe that directed flow is crossed outdoor heat converter 120, and above-mentioned refrigerant pipe is used to flow through flowing of outdoor heat converter 120 cold-producing mediums.The outer tube 172b that is positioned at the pipe 172a outside has the diameter more relatively large than pipe 172a, is used to guide a part to flow through the adverse current of the cold-producing medium of interior pipe 172a.
