Description

Technical Field

[0001] The present application relates to the technical field of smart home appliances, for example, to an air conditioning system. Background Art

[0002] For places such as office buildings, apartments, shopping malls and hotels, due to the large overall area and the fact that the venues are divided into multiple independent small spaces, ordinary split-type "one-to-one" air-conditioning models often cannot meet the actual usage needs of these places. Therefore, "one-to-many" commercial air-conditioning models came into being. The structure of "one-to-many" air-conditioning has multiple indoor units, each of which can be installed in multiple rooms respectively, and multiple indoor units share one outdoor unit. Compared with split-type "one-to-one" air-conditioning, "one-to-many" air-conditioning is cheaper and requires smaller outdoor unit installation space.

[0003] When a "one-to-many" air conditioner is in use, after any indoor unit is turned on, the outdoor unit needs to start and operate to deliver cooling / heat to the indoor unit. As the number of indoor units turned on increases, the cooling / heat output of the outdoor unit also increases accordingly. In this way, the power parameters of the outdoor unit's cooling / heating are designed to at least meet the cooling / heat supply needs of all indoor units, that is, the capacity of the outdoor unit must be at least greater than the sum of the capacities of all indoor units. In order to solve the problem of waste of excess energy output from the outdoor unit when a small number of indoor units are enabled, an optional method is to configure the air conditioning system with energy storage components such as a hot water tank, and use the energy storage components to absorb and store excess energy.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] Although the above design can improve the matching between the outdoor unit output capacity and the indoor unit consumption, the energy source of the above air-conditioning system all comes from the air-conditioning system, and considering that there will be additional energy consumption in the process of energy storage and reuse, the energy-saving effect of this type of air-conditioning system is not good.

[0067] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0068] Combination Figure 1 As shown, in an optional embodiment, the air conditioning system mainly includes a refrigerant heat exchange module 100, an energy storage heat exchange module and an external cold and heat source component 300. Among them, the refrigerant heat exchange module 100 is mainly used to realize the function of cooling or heating the indoor environment through indoor units and other components, and the energy storage heat exchange module is mainly used to exchange heat with the refrigerant heat exchange module 100 and the external heat source, which may specifically include accumulating heat / cold from the refrigerant heat exchange module 100 and the external heat source, and releasing the accumulated heat / cold to the refrigerant heat exchange module 100; the external cold and heat source component 300 is mainly used to input additional heat / cold into the refrigerant heat exchange module 100 and the energy storage heat exchange module in the form of direct heat transfer or indirect heat transfer.

[0069] The components of the refrigerant heat exchange module 100 mainly include a compressor 103, an outdoor heat exchanger 102, an indoor heat exchanger 101, a throttling device and a four-way valve 104, etc.

[0070] Here, the body composition of the refrigerant heat exchange module 100 includes two parts, namely an indoor unit and an outdoor unit. The indoor unit is arranged on the indoor side, and the indoor heat exchanger 101 is arranged in the indoor unit, which is used to exchange heat between the refrigerant and the indoor environment to absorb indoor heat for cooling or release heat for heating; the outdoor unit is arranged on the outdoor side, and components such as a compressor 103, an outdoor heat exchanger 102 and a four-way valve 104 are arranged in the outdoor unit.

[0071] The multiple components of the refrigerant heat exchange module 100 are connected by refrigerant pipelines and are constructed into a refrigerant circulation loop filled with refrigerant. The refrigerant can circulate along the refrigerant circulation loop to achieve heat transfer between the indoor and outdoor sides.

[0072] The embodiments of the present disclosure and the following text are described by taking a "one-to-many" air conditioner as an example, wherein the indoor unit has multiple indoor heat exchangers 101, such as Figure 1 and 2 The refrigerant heat exchange module 100 shown is provided with three indoor heat exchangers 101, which are connected in parallel and each parallel branch is provided with a switching valve. The switching valve can be used to control the on-off state of each parallel branch, and then control the specific activated indoor heat exchanger 101.

[0073] In some optional embodiments, the energy storage and heat exchange module includes an indoor energy storage part and an outdoor energy storage part that can exchange heat with each other, wherein the indoor energy storage part is arranged on the indoor side, and the outdoor energy storage part is arranged on the outdoor side, and the two are connected to each other so as to realize the transfer and transportation of heat / cold from the indoor side to the outdoor side, or from the outdoor side to the indoor side.

[0074] Here, the indoor energy storage unit is connected to the indoor heat exchanger 101 to form an indoor energy storage flow path, and the outdoor energy storage unit is connected to the outdoor heat exchanger 102 to form an outdoor energy storage flow path; the energy storage heat exchange module is configured to controllably transport cold / heat between the indoor side and the outdoor side.

[0075] The external cold / heat source assembly 300 in this embodiment is disposed on an outdoor energy storage flow path, and is specifically configured to controllably transport cold / heat to the outdoor energy storage flow path.

[0076] In some embodiments, the external cold and heat source assembly 300 includes an energy tower module 320. The energy tower module 320 is used to provide cold / heat, and the external cold and heat source assembly 300 is arranged on the outdoor energy storage flow path, so that the external cold and heat source assembly 300 can controllably transport cold / heat to the outdoor energy storage flow path, for example, transport cold to the outdoor energy storage flow path under the cooling condition in summer, or transport heat to the outdoor energy storage flow path under the heating condition in winter.

[0077] Optionally, the type of the energy tower module 320 may include a cooling tower module. The cooling tower module can cool down and dissipate the energy medium by water cooling or air cooling, so as to output a low-temperature energy medium. In this way, by making the low-temperature energy medium output by the cooling tower module exchange heat with the energy storage medium flowing through the outdoor energy storage flow path, and using the low-temperature energy medium to absorb the heat of the energy storage medium, the function of outputting cold to the refrigerant heat exchange module 100 can be achieved.

[0078] Alternatively, the type of the energy tower module 320 may include a heat source tower module. The heat source tower module may utilize wind source heat or ground source heat to heat the energy medium, thereby being able to output the energy medium in a high temperature state. In this way, by heat exchanging the high temperature energy medium output by the heat source tower module with the energy storage medium flowing through the outdoor energy storage flow path, and transferring the heat to the energy storage medium, the function of outputting heat to the refrigerant heat exchange module 100 can be achieved.

[0079] In some optional embodiments, the energy medium type of the energy tower module 320 is water, ethylene glycol, etc.

[0080] In addition, the external cold and heat source component 300 also includes an intermediate heat exchanger 310, which has a first heat exchange part and a second heat exchange part that can exchange heat with each other, wherein the first heat exchange part is connected to the outdoor energy storage flow path, and the second heat exchange part can be connected to the energy tower module 320 and form an energy medium circulation loop to enable heat exchange between the energy storage medium and the energy medium.

[0081] Therefore, in this embodiment, the energy medium and the energy storage medium of the intermediate heat exchanger 310 are heat exchanged in the form of indirect heat exchange, thereby avoiding the energy medium and the energy storage medium used in the energy tower module from directly contacting and contaminating each other.

[0082] In some further optional embodiments, the energy tower module 320 further includes a water replenishment pipeline 321, which can be used to replenish energy medium to the energy tower module 320, thereby timely replenishing the naturally lost energy medium and ensuring the medium circulation volume and energy supply efficiency of the energy medium circulation loop.

[0083] Optionally, the water supply pipeline 321 includes an automatic water supply pipeline and a manual water supply pipeline. The automatic water supply pipeline includes a liquid level meter and a water pump. The liquid level meter is arranged in the energy tower module 320 and can automatically detect the water level of the energy medium in the energy tower module 320. At the same time, when the liquid level meter detects that the water level of the energy medium is low and the total amount of the energy medium is insufficient, the water pump can be controlled to start and the water pump can be used to supplement the energy tower module 320 with energy medium.

[0084] In some other embodiments, the energy tower module 320 further includes a drain pipe 322 and / or an overflow pipe 323. The drain pipe 322 is used to allow the energy tower module to remove contaminated energy medium. The overflow pipe 323 can be used to discharge excess energy medium when there is too much energy medium in the energy tower module 320, thereby stabilizing the flow path pressure in the energy medium circulation loop.

[0085] In other optional embodiments, the external cold and heat source assembly 300 also includes an external energy storage tank 330, which is connected in series or parallel to the energy medium circulation loop, and can be used to store additional cold / heat and release this part of cold / heat to the energy medium circulation loop.

[0086] By setting up an external energy storage box 330, cold / heat can be supplied to the energy medium circulation loop during the startup phase of the energy tower module 320 or when the energy generation is insufficient, thereby accelerating the energy supply response speed of the external cold and heat source component 300 and improving the operating efficiency of the air conditioner.

[0087] The present application provides a variety of optional matching structures of the refrigerant heat exchange module 100 and the energy storage heat exchange module. The following describes two matching structures in conjunction with the accompanying drawings:

[0088] The first cooperation form of the refrigerant heat exchange module 100 and the energy storage heat exchange module: the indoor energy storage part and the outdoor energy storage part perform indirect heat exchange.

[0089] In an optional embodiment, the indoor energy storage part includes an indoor energy storage box 211 which is constructed in the form of a box and the interior of which is used as a space for accommodating an energy storage medium. The indoor energy storage box 211 is mainly used to store energy indoors, and the indoor energy storage box 211 is connected to the indoor heat exchanger 101 to achieve energy transfer between the indoor energy storage box 211 and the indoor heat exchanger 101. The energy transfer form at least includes that the indoor energy storage box 211 can controllably store cold / heat from the indoor heat exchanger 101, or release cold / heat to the indoor heat exchanger 101.

[0090] It should be noted that one of the optional ways for the indoor energy storage box 211 to store cold energy is that after the energy storage medium with a higher temperature in the indoor energy storage box 211 is transported to the indoor heat exchanger 101, its heat is absorbed by the outside world so that its own temperature is reduced, so that the energy storage medium becomes a low-temperature medium, and is sent back to the indoor energy storage box 211 for storage. That is, in this embodiment, cold energy is stored in the indoor energy storage box 211 using the energy storage medium itself as a carrier.

[0091] Correspondingly, one of the optional ways for the indoor energy storage box 211 to release cold is that after the energy storage medium with a lower temperature in the indoor energy storage box 211 is transported to the indoor heat exchanger 101, it absorbs external heat (equivalent to releasing cold to the outside) to increase its own temperature, so that the energy storage medium becomes a medium-high temperature medium and is sent back to the indoor energy storage box 211.

[0092] Similarly, one of the optional ways for the indoor energy storage box 211 to store heat is that after the energy storage medium with a lower temperature in the indoor energy storage box 211 is transported to the indoor heat exchanger 101, it absorbs heat from the outside to increase its own temperature, so that the energy storage medium becomes a medium-high temperature medium, and is sent back to the indoor energy storage box 211 for storage.

[0093] Correspondingly, one of the optional ways for the indoor energy storage box 211 to release heat is that after the energy storage medium with a higher temperature in the indoor energy storage box 211 is transported to the indoor heat exchanger 101, its heat is absorbed by the outdoor unit to reduce its own temperature, so that the energy storage medium becomes a low-temperature medium and is sent back to the indoor energy storage box 211.

[0094] In some other optional embodiments, the indoor energy storage box 211 also includes a phase change material filled therein, which can absorb cold / heat in the energy storage medium flowing through it, and release cold / heat to the energy storage medium; therefore, in this embodiment, cold / heat can also be stored in the indoor energy storage box 211 using the phase change material as a carrier.

[0095] In this embodiment, the body of the indoor energy storage box 211 is made of insulation or low thermal conductivity material, or an insulation layer is provided on the inner and outer walls of the body to reduce the heat exchange between the environment in which the indoor energy storage box 211 is located and the energy storage medium inside the indoor energy storage box 211, thereby being able to store cold / heat for a longer period of time.

[0096] Optionally, an on-off valve is provided on the liquid inlet side of the indoor energy storage box 211, and the on-off valve can be used to control the on-off state of the liquid inlet side pipeline of the indoor energy storage box 211; another on-off valve is provided on the liquid outlet side of the indoor energy storage box 211, and the on-off valve can be used to control the on-off valve provided on the indoor energy storage box 211 and / or the liquid outlet side.

[0097] In some embodiments, the indoor energy storage unit further includes an indoor driving pump, which is configured to controllably drive the energy storage medium to circulate between the indoor heat exchanger 101 , the indoor energy storage tank 211 and / or the intermediate heat exchange unit 230 .

[0098] In some other optional embodiments, since some types of energy storage media will cause their own volume to change when the heat / cold amount changes, this may cause the volume of the energy storage medium after the change to exceed the volume design requirement of the indoor energy storage tank 211. In order to improve the safety of use and reduce the damage to the indoor energy storage tank 211 caused by the change in the volume of the energy storage medium, the indoor energy storage unit also includes a first safety valve, which is arranged on the liquid outlet side of the indoor energy storage tank 211. The first safety valve is configured to be turned on to release pressure when the flow path pressure is greater than the set pressure value.

[0099] Optionally, the set pressure value of the first safety valve is 0.5 MPa. Here, the set pressure value of the first safety valve can be adaptively adjusted according to the carrying capacity of the indoor energy storage box 211, and the present application is not limited thereto.

[0100] In some other optional embodiments, during the long-term use of the indoor heat storage module, there may be a problem of impurities being mixed into the internal flow path. Therefore, in order to reduce the impact of these impurities on other pipeline components of the indoor energy storage unit, such as avoiding clogging of the aforementioned indoor drive pump; the indoor energy storage unit also includes a first filter, which is configured to filter out impurities from the energy storage medium flowing through the indoor energy storage box 211.

[0101] Optionally, the first filter is arranged on the liquid inlet side pipeline of the aforementioned indoor driving pump to filter and purify the energy storage medium before it flows into the indoor driving pump.

[0102] In some other optional embodiments, the indoor energy storage part also includes a first expansion tank, which is configured to provide a variable volume space for the volume change caused by the change in hot and cold temperatures of the energy storage medium in the flow path; here, the working principle of the first expansion tank is: when the external pressurized medium enters the first expansion tank, the nitrogen sealed in the tank is compressed. According to Boyle's gas law, the volume of the gas decreases and the pressure increases after being compressed, thereby freeing up part of the tank volume originally occupied by the gas, and filling the medium into this part of the volume until the gas pressure in the expansion tank is consistent with the medium hydraulic pressure; when the medium pressure decreases (the gas pressure in the expansion tank is greater than the medium hydraulic pressure), the gas expands and squeezes the medium in the tank out of the tank again so that this part of the medium returns to the indoor energy storage circuit to participate in the circulation.

[0103] The first expansion tank can provide a certain volume change space for the energy storage medium, thereby reducing the squeezing force of the energy storage medium volume change on the relevant components of the indoor energy storage part.

[0104] Similarly, in some optional embodiments, the indoor energy storage unit further includes a first buffer tank, which is configured to store at least part of the energy storage medium and provide a variable capacity space for volume changes caused by changes in the temperature of the energy storage medium.

[0105] The outdoor energy storage unit includes an outdoor energy storage box 221. Optionally, the flow path form and component composition constructed between the outdoor energy storage unit and the outdoor heat exchanger 102 are substantially the same as the flow path form and component composition between the indoor energy storage unit and the indoor heat exchanger 101 in the aforementioned embodiment, and the details can be referred to the aforementioned embodiment, which will not be described in detail here.

[0106] In this embodiment, the indoor energy storage flow path includes an indoor intermediate heat exchange pipeline 212, which includes an intermediate heat exchange pipe section arranged in the intermediate heat exchange part 230 and used for heat exchange with the outdoor side; the outdoor energy storage flow path includes an outdoor intermediate heat exchange pipeline 222, which includes an intermediate heat exchange pipe section arranged in the intermediate heat exchange part 230 and used for heat exchange with the indoor side.

[0107] The energy storage heat exchange module also includes an intermediate heat exchange part 230, which is respectively connected to the intermediate heat exchange pipe section of the indoor intermediate heat exchange pipeline 212 and the intermediate heat exchange pipe section of the outdoor energy storage box 221 through the outdoor intermediate heat exchange pipeline 222, so that the indoor energy storage part and the outdoor energy storage part can perform heat exchange under control in the intermediate heat exchange part 230.

[0108] Optionally, the outdoor energy storage box 221 and the outdoor heat exchanger 102 are both arranged on the outdoor intermediate heat exchange pipeline 222 and form an outdoor medium circulation loop 251.

[0109] In this embodiment, the external cold and heat source component 300 is arranged on the outdoor intermediate heat exchange pipeline 222, so the external cold and heat source component 300 is configured to allow the energy storage medium flowing through the outdoor intermediate heat exchange pipeline 222 to exchange heat with the external heat source, so as to use the external low-temperature heat source to cool the energy storage medium, or use the external high-temperature heat source to heat the energy storage medium.

[0110] In some other embodiments, the outdoor energy storage flow path also includes an outdoor heat exchange branch 223, which is connected in parallel to the intermediate heat exchange pipe section of the outdoor intermediate heat exchange pipe 222, so that the outdoor energy storage tank 221, the outdoor heat exchanger 102 and the external cold and heat source component 300 form a separate circulation loop, and the energy storage medium can be transferred along the separate circulation loop between the outdoor energy storage tank 221, the outdoor heat exchanger 102 and the external cold and heat source component 300 to transfer heat / cold.

[0111] In this embodiment, a plurality of valve components are further provided, and the specific flow direction of the energy storage medium in the outdoor energy storage flow path is switched by controlling the on-off of the valve components.

[0112] Optionally, the valve component includes a first parallel valve 241 and a second parallel valve 242 , wherein the first parallel valve 241 is arranged on the outdoor heat exchange branch 223 , and the second parallel valve 242 is arranged on the middle heat exchange pipe section of the outdoor middle heat exchange pipe 222 .

[0113] Optionally, when the first parallel valve 241 is closed and the second parallel valve 242 is opened, the outdoor heat exchanger 102, the outdoor energy storage tank 221, the external cold and heat source assembly 300 and the intermediate heat exchange part 230 form a circulation loop, and the flow order of the energy storage medium is: outdoor heat exchanger 102→outdoor energy storage tank 221→external cold and heat source assembly 300→intermediate heat exchange part 230→outdoor heat exchanger 102.

[0114] Alternatively, when the first parallel valve 241 is open and the second parallel valve 242 is closed, the outdoor heat exchanger 102, the outdoor energy storage tank 221, and the external cold and heat source assembly 300 form a circulation loop, and the flow order of the energy storage medium is: outdoor heat exchanger 102 → outdoor energy storage tank 221 → external cold and heat source assembly 300 → outdoor heat exchanger 102.

[0115] In this way, by switching the above-mentioned different flow path states, the actual heat exchange object of the external heat source can be selectively limited to the indoor side and / or the outdoor side. For example, in the first state mentioned above, the cold / heat input by the external heat source is respectively delivered to the indoor energy storage tank 211 and the outdoor energy storage tank 221; and in the second state mentioned above, the cold / heat input by the external heat source is delivered to the outdoor energy storage tank 221.

[0116] In this embodiment, for the outdoor side, the cold / heat input by the external heat source can be stored in the outdoor energy storage tank 221, or it can be directly used along the flow path for heat exchange with the outdoor heat exchanger 102; for the indoor side, the cold / heat input by the external heat source can be stored in the indoor energy storage tank 211, or it can be directly used along the flow path for heat exchange with the indoor heat exchanger 101.

[0117] The second coordination form between the refrigerant heat exchange module 100 and the energy storage heat exchange module: the indoor energy storage part and the outdoor energy storage part perform indirect heat exchange.

[0118] In some embodiments, the indoor energy storage unit includes an indoor energy storage box 211, which is connected to the indoor heat exchanger 101. The structure of the indoor energy storage box 211, the connection structure with the indoor heat exchanger 101, and other auxiliary accessories can refer to the above embodiments and are not described in detail here.

[0119] In this embodiment, the outdoor energy storage unit includes an outdoor heat exchange pipeline 224 , at least part of which is disposed in the outdoor heat exchanger 102 , so that the energy storage medium flowing through the outdoor heat exchange pipeline 224 can perform heat exchange with the outdoor heat exchanger 102 .

[0120] Here, the outdoor heat exchange pipeline 224 is also connected to the indoor energy storage tank 211. The indoor energy storage tank 211 and the indoor heat exchanger 101 are configured as an indoor energy storage circuit, and the energy storage medium can flow along the indoor energy storage circuit to transport cold / heat; wherein part of the pipeline of the indoor energy storage circuit is used as a parallel pipe section 213, and both ends of the outdoor heat exchange pipeline 224 are connected to the parallel pipe section 213, and the parallel pipe section 213 is located on the liquid inlet side of the indoor energy storage tank 211. Under this connection form, the energy storage medium from the indoor heat exchanger 101 can be divided into two flow directions, one of which is that the energy storage medium does not pass through the parallel pipe section 213 and directly flows into the outdoor heat exchange pipeline 224, and then flows back to the indoor energy storage circuit and flows into the indoor energy storage tank 211; the other is that the energy storage medium flows into the indoor energy storage tank 211 after passing through the parallel pipe section 213.

[0121] Optionally, a parallel connection valve 244 is provided on the parallel connection pipe section 213 , and the on-off state of the parallel connection pipe section 213 can be adjusted by controlling the parallel connection valve 244 .

[0122] The external cold and heat source assembly 300 in this embodiment is disposed on the outdoor heat exchange pipeline 224 to cool the energy storage medium flowing through the outdoor heat exchange pipeline 224 using an external low-temperature heat source, or to heat the energy storage medium using an external high-temperature heat source.

[0123] Optionally, the air conditioning system further includes a control valve 243 , which is disposed on the outdoor heat exchange pipeline 224 . By controlling the on / off state of the control valve 243 , the on / off state of the outdoor heat exchange pipeline 224 can be switched.

[0124] For example, when the control valve 243 is in the open state, the outdoor heat exchange pipeline 224 is in the conducting state. At this time, the energy storage medium can flow along the outdoor heat exchange pipeline 224 and transport the heat / cold input from the external heat source to one or more of the outdoor heat exchanger 102, the indoor heat exchanger 101, and the indoor energy storage unit.

[0125] When the control valve 243 is in a closed state, the outdoor heat exchange pipeline 224 is in a blocked state, and the energy storage medium does not flow along the outdoor heat exchange pipeline 224 at this time.

[0126] In the aforementioned embodiments, Figure 3 and Figure 4 As shown, the air conditioning system further includes an outdoor medium circulation loop 251 and / or an indoor medium circulation loop 252 .

[0127] The outdoor medium circulation loop 251 is connected to the outdoor heat exchanger 102, the indoor energy storage unit and the outdoor energy storage unit so that when the energy storage medium flows in the outdoor medium circulation loop 251, the cold / heat is transferred from the outdoor heat exchanger 102 to at least one of the indoor energy storage unit and the outdoor energy storage unit, or the cold / heat is transferred from at least one of the indoor energy storage unit and the outdoor energy storage unit to the outdoor heat exchanger 102.

[0128] For example, in the process of the energy storage medium flowing along the outdoor medium circulation loop 251, cold / heat can be transported from the outdoor heat exchanger 102 to at least one of the indoor energy storage part and the outdoor energy storage part. For example, in the cooling mode, the outdoor heat exchanger 102 is used as a "condenser". At this time, the outdoor heat exchanger 102 releases heat to the outside, and the energy storage medium can be transported to the indoor energy storage part or the outdoor energy storage part through the outdoor medium circulation loop 251, so that the indoor energy storage part or the outdoor energy storage part can store heat; for example, in the heating mode, the outdoor heat exchanger 102 is used as an "evaporator". At this time, the outdoor heat exchanger 102 absorbs heat from the outside (equivalent to releasing cold), and cold can be transported to the indoor energy storage part or the outdoor energy storage part through the outdoor medium circulation loop 251.

[0129] The indoor medium circulation loop 252 is connected to the indoor heat exchanger 101, the indoor energy storage unit and the outdoor energy storage unit, so that when the energy storage medium flows in the indoor medium circulation loop 252, the cold / heat is transferred from the indoor heat exchanger 101 to at least one of the indoor energy storage unit and the outdoor energy storage unit, or the cold / heat is transferred from at least one of the indoor energy storage unit and the outdoor energy storage unit to the outdoor heat exchanger 102.

[0130] For example, in the process of the energy storage medium flowing along the outdoor internal mass circulation loop, cold / heat can be transported from the indoor heat exchanger 101 to at least one of the indoor energy storage part and the outdoor energy storage part. For example, in the cooling mode, the indoor heat exchanger 101 is used as an "evaporator". At this time, the indoor heat exchanger 101 absorbs heat from the outside (equivalent to releasing cold), and the energy storage medium can be transported to the indoor energy storage part or the outdoor energy storage part through the indoor medium circulation loop 252, so that the indoor energy storage part or the outdoor energy storage part can store cold; for example, in the heating mode, the indoor heat exchanger 101 is used as a "condenser". At this time, the indoor heat exchanger 101 releases heat to the outside, and heat can be transported to the indoor energy storage part or the outdoor energy storage part through the outdoor medium circulation loop 251.

[0131] In some embodiments, in combination Figure 5 As shown, the air conditioning system further includes a radiation heat exchange module, which is used for exchanging heat with the indoor environment through thermal radiation.

[0132] The radiation heat exchange module includes one or more radiation heat exchangers 410, each of which is connected to the indoor heat exchanger 101 and is configured to form an indoor radiation circulation loop, which is configured to perform heat exchange with the outside by using the energy storage medium flowing through it.

[0133] Optionally, the radiation heat exchanger 410 can be directly connected to the indoor energy storage flow path between the indoor heat exchanger 101 and the indoor energy storage box 211, that is, under this flow path form, the flow direction of the energy storage medium is: indoor heat exchanger 101 → indoor energy storage box 211 → radiation heat exchanger 410 → indoor heat exchanger 101.

[0134] When low-temperature energy storage medium flows through the radiation heat exchanger 410, the radiation heat exchanger 410 can cool down the room; and when medium-high temperature energy storage medium flows through the radiation heat exchanger 410, the radiation heat exchanger 410 can heat up the room.

[0135] Optionally, the indoor radiation circulation loop further includes a radiation valve 420 , which is disposed on the indoor radiation circulation loop and is used to control the on / off of the indoor radiation circulation loop, and further control the start and stop of the heat exchange operation of the corresponding radiation heat exchanger 410 .

[0136] In some embodiments, the number of indoor heat exchangers 101 is at least two, and the liquid inlet ends of the energy storage media corresponding to each indoor heat exchanger 101 are connected in parallel to the indoor radiation circulation loop, and the liquid outlet ends are connected in parallel to the indoor radiation circulation loop; in this way, the energy storage media flowing out of different indoor heat exchangers 101 can be mixed at the parallel node and then transported to the radiation heat exchanger 410, which can keep the temperature state of the energy storage media flowing into each radiation heat exchanger 410 uniform, thereby making the radiation heat exchange effect of each radiation heat exchanger 410 on the corresponding indoor area more consistent.

[0137] Optionally, the radiation heat exchange module includes multiple radiation heat exchangers 410, such as the two radiation heat exchangers 410 shown in the figure, and the liquid inlet interfaces corresponding to the radiation heat exchangers 410 are connected in parallel to the indoor radiation circulation loop, and the liquid outlet interfaces are connected in parallel to the indoor radiation circulation loop. In the embodiment, different radiation heat exchangers 410 can be arranged in the same indoor area, or in different indoor areas, and the specific arrangement can be adjusted according to the actual heat exchange needs, and this application does not limit this.
