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] Air conditioners are currently widely used household appliances. Their excellent role in maintaining indoor temperature and creating a comfortable indoor environment makes them an indispensable part of today's residents' daily life. However, for existing air conditioner products, there are still some problems in indoor temperature control. Wall-mounted air conditioners are generally installed at a higher position close to the ceiling, or cabinet air conditioners are generally installed in indoor corners. When the air conditioner is running, it will have a faster effect on the temperature change of indoor spaces that are closer, and a slower effect on the temperature change of indoor spaces that are farther away. For example, in the indoor winter heating mode, the air conditioner blows hot air, resulting in high temperature at the air conditioner outlet and low temperature far away from the air conditioner outlet, resulting in a large temperature difference between various indoor areas.

[0003] In order to improve the above-mentioned problems in the related technology, one of the current methods is to combine the air-conditioning system and the water system, and use the air-conditioning system and the water system to provide cooling / heating for different indoor areas at the same time. For example, the water system is designed by adding a new intermediate heat exchanger, using the heat of the refrigerant to heat the water, and the heated hot water is then transported to the radiation module for radiant heating.

[0046] 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.

[0047] Combination Figure 1 As shown, in an optional embodiment, the air conditioning system mainly includes a refrigerant heat exchange module 100, a radiation module and an external heat source component. Among them, the refrigerant heat exchange module 100 is mainly used to realize the function of cooling or heating the indoor environment through components such as an indoor unit; the radiation module is mainly used to cool or heat the indoor environment through devices such as a radiation heat exchanger 210; the external heat source component is mainly used as an intermediate transfer component, which is configured to connect the refrigerant heat exchange module 100, the radiation module and the external heat source, so that the external heat source can input heat / cold in the form of direct heat transfer or indirect heat transfer, and release it at the refrigerant heat exchange module 100 and the radiation module.

[0048] In this embodiment, 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.

[0049] 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.

[0050] 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.

[0051] 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 The refrigerant heat exchange module 100 shown is provided with two 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.

[0052] In some embodiments, the indoor heat exchanger 101 is a type three-medium heat exchanger, which has a refrigerant heat exchange pipe section, a radiation working fluid heat exchange pipe section and an air channel. It is configured to enable heat exchange between any two or three of the refrigerant heat exchange pipe section, the radiation working fluid heat exchange pipe section and the air channel.

[0053] Among them, the refrigerant heat exchange pipe section is used to be connected with the pipeline corresponding to the refrigerant heat exchange module 100, and the radiation working fluid heat exchange pipe section is used to be connected with the pipeline corresponding to the indoor radiation working fluid flow path; the air channel is connected with the internal air duct of the indoor unit, so that the indoor air can exchange heat with the refrigerant pipe section and / or the radiation working fluid heat exchange pipe section through the air channel.

[0054] Exemplarily, a three-medium heat exchanger is used to allow the refrigerant flowing through the refrigerant heat exchange pipe section to exchange heat with the radiant working fluid flowing through the radiant working fluid heat exchange pipe section, such as using a high-temperature refrigerant to heat up the radiant working fluid, or using a low-temperature refrigerant to cool down the radiant working fluid; and a three-medium heat exchanger is used to allow the refrigerant flowing through the refrigerant heat exchange pipe section to exchange heat with the air flowing through the air channel, such as using a high-temperature refrigerant to heat up the air, or using a low-temperature refrigerant to cool down the air; and a three-medium heat exchanger is used to allow the refrigerant flowing through the refrigerant heat exchange pipe section to simultaneously exchange heat with the radiant working fluid flowing through the radiant working fluid heat exchange pipe section and the air flowing through the air channel, such as using a high-temperature refrigerant to simultaneously heat up the radiant working fluid and the air, or using a low-temperature refrigerant to simultaneously cool down the radiant working fluid and the air, etc.

[0055] In some optional embodiments, the radiation module mainly includes a radiation heat exchanger 210 and a radiation pipeline 230, wherein the radiation heat exchanger 210 is connected to the radiation working fluid heat exchange pipe section of the indoor heat exchanger 101 through the radiation pipeline 230 and is constructed as an indoor radiation working fluid flow path, which is configured to utilize the radiation working fluid flowing through it to exchange heat with the outside. For example, when low-temperature radiation working fluid flows through the radiation heat exchange module, the radiation heat exchange module can cool the room; and when medium-high temperature radiation working fluid flows through the radiation heat exchange module, the radiation heat exchange module can heat the room.

[0056] In some embodiments, the indoor radiation working fluid flow path also includes a driving pump, which is arranged on the indoor radiation working fluid flow path and is used to drive the radiation working fluid to flow along the indoor radiation working fluid flow path. Therefore, in this embodiment, the driving pump can be used to provide driving force for the flow of the indoor radiation working fluid flow path.

[0057] In some embodiments, the indoor radiation working medium flow path further includes a radiation valve 220 , and the radiation valve 220 is used to control the on / off state of the indoor radiation working medium flow path, thereby realizing control of the heat exchange start / stop state of the radiation heat exchanger 210 .

[0058] When the radiation module needs to be activated for cooling / heating, the drive pump can be controlled to start and the radiation valve 220 can be opened to conduct the indoor radiation working fluid flow path; when the radiation module does not need to be activated for cooling / heating, the drive pump can be controlled to stop and the radiation valve 220 can be closed to block the indoor radiation working fluid flow path.

[0059] Optionally, the type of the radiation working fluid is water or ethylene glycol.

[0060] Optionally, the type of the radiation heat exchanger 210 is a floor heating pipe network, a column type, a plate group type heat sink / cooler, etc.

[0061] In some optional embodiments, the external heat source component is disposed on the indoor radiation working fluid flow path, and is configured to controllably transport external input cold / heat to at least one of the indoor heat exchanger 101 and the radiation module.

[0062] For the form of inputting heat / cold in the form of direct heat transfer, as shown in the figure, the external heat source component includes a heat source input port 311 and a heat source output port 312, wherein the heat source input port 311 is arranged at the first end of the indoor radiation working fluid flow path, which serves as the inlet of the indoor radiation working fluid flow path for the radiation working fluid to be input, and the heat source output port 312 is arranged at the second end of the indoor radiation working fluid flow path, which serves as the outlet for the radiation working fluid to flow out of the indoor radiation working fluid flow path after heat exchange.

[0063] Optionally, the indoor heat exchanger 101 and the radiation module in this embodiment are arranged in series at the first end and the second end of the indoor radiation medium flow path, and the flow order of the radiation medium defined by this flow path is: external heat source → heat source input port 311 → radiation module (or indoor heat exchanger 101) → indoor heat exchanger 101 (or radiation module) → heat source output port 312 → external heat source. In this flow path form, the radiation medium input from the external heat source successively exchanges heat with the radiation module and the indoor heat exchanger 101 to transfer heat / cold to the radiation module and the indoor heat exchanger 101 respectively, and the two heat exchanges can effectively improve the utilization rate of the energy input from the external heat source.

[0064] In some embodiments, the radiation module is arranged on one side of the indoor radiation working fluid flow path adjacent to the heat source input port 311, that is, the radiation working fluid flowing in through the heat source input end preferentially flows through the radiation heat exchanger 210 of the radiation module. Here, since the radiation working fluid input first has not undergone heat exchange and contains more heat / cold, the above-mentioned setting can make this part of the larger heat / cold be used preferentially for external heat exchange of the radiation module.

[0065] Compared with the air-cooled heat exchange method of the refrigerant heat exchange module 100, the radiation heat exchange module exchanges heat to the outside based on the principle of thermal radiation. Its heat exchange method is gentler, but the heat exchange rate is lower than the air-cooled heat exchange. In this embodiment, more heat / cold is supplied to the radiation module first, which can enhance the efficiency of radiation heat exchange while ensuring a smooth heat exchange effect.

[0066] Exemplarily, the external heat source is a municipal heating pipe network system, the application condition is a winter heating condition, and the radiation working fluid is high-temperature hot water; at this time, the municipal heating pipe network system is connected to the heat source input port 311 and the heat source output port 312, and the high-temperature hot water is sent from the heat source input port into the indoor radiation working fluid flow path. The high-temperature hot water is heat exchanged in the radiation heat exchanger 210 and the indoor heat exchanger 101 in turn, and the heat is transferred to the indoor environment in the form of thermal radiation and air-cooled heat exchange. The cooled hot water flows back to the municipal heating pipe network system via the heat source output port 312.

[0067] Optionally, when the external heat source is in the form of the above-mentioned municipal heating pipe network system, since the municipal heating pipe network system itself is equipped with a radiation working fluid drive, it is possible to choose not to equip a separate drive pump in this embodiment.

[0068] During long-term use, impurities (such as rust, scale, etc.) mixed in the radiation working fluid directly input by the external heat source may be deposited in the indoor radiation working fluid flow path and components such as the radiation heat exchanger 210 and the indoor heat exchanger 101, causing problems such as the pipe diameter becoming smaller or even clogging the pipe. Therefore, in order to solve the above technical problems, in some embodiments, the external heat source component also includes a filter 400, which is arranged at the heat source input port 311, and is configured to filter the radiation working fluid flowing through. After filtering, the radiation working fluid flows into the indoor radiation working fluid flow path, thereby reducing the impurity content entering the indoor radiation working fluid flow path and improving the cleanliness of the pipeline.

[0069] Optionally, the filter 400 is in the form of a filter screen.

[0070] In some embodiments, the filter 400 is detachably connected to the pipeline, so that the impurities filtered in the filter 400 can be easily cleaned regularly.

[0071] During actual use, some air bubbles may gradually accumulate in the indoor radiation working fluid flow path. The reasons for this are: residual air inside has not been completely exhausted during the on-off switching connection between the external heat source and the indoor radiation working fluid, or gas molecules are dissolved in the radiation working fluid input by the external heat source; these air bubbles will cause "air blockage" problems, affecting the flow of the radiation working fluid in the indoor radiation working fluid flow path. Therefore, in order to solve the above technical problems, in some embodiments, the external heat source assembly also includes an automatic exhaust valve 500, which is arranged on the indoor radiation working fluid flow path, and is configured to automatically exhaust gas impurities in the indoor radiation working fluid flow path.

[0072] Optionally, the automatic exhaust valve 500 is disposed at the heat source output port 312 .

[0073] Generally, with respect to the installation position in the indoor space, the radiation heat exchanger 210 is generally installed at a position with a lower spatial height, while the indoor heat exchanger 101 of the refrigerant heat exchange module 100 is installed at a position with a relatively higher spatial height. In this way, in the flow direction of the radiation working fluid defined in the aforementioned embodiment successively flowing through the radiation heat exchanger 210 and the indoor heat exchanger 101, the heat source output port 312 to which the radiation working fluid flows from the indoor heat exchanger 101 is also located at a higher spatial height position. Since the density of air bubbles themselves is smaller than that of the radiation working fluid, they are easy to float up and accumulate at a higher position. Therefore, the setting position of the automatic exhaust valve 500 in this embodiment is conducive to discharging air bubbles in the flow path.

[0074] When an external heat source supplies radiation working fluid, there may be an unstable flow rate. In order to more timely and accurately monitor the changes in the radiation working fluid quality in the indoor radiation working fluid flow path, in some embodiments, the external heat source assembly also includes a liquid level detector, which is arranged in the indoor radiation working fluid flow path. The liquid level detector can reflect the actual radiation working fluid quality in the indoor radiation working fluid by detecting the changes in the liquid level of the radiation working fluid.

[0075] In some other optional embodiments, for the input of heat / cold in the form of indirect heat transfer, as shown in the figure, the indoor radiation working fluid flow path is constructed in a circulation loop form, and the flow direction of the radiation working fluid defined by the flow path form is: indoor heat exchanger 101→radiation heat exchanger 210→indoor heat exchanger 101.

[0076] Here, the external heat source component includes an intermediate heat exchanger 320, and the radiation heat exchanger 210 is arranged on the indoor radiation working fluid flow path and is connected to the external heat source, so that the radiation working fluid in the indoor radiation working fluid flow path can exchange heat with the heat working fluid of the external heat source through the intermediate heat exchanger 320.

[0077] Optionally, the intermediate heat exchanger 320 is arranged on the flow pipe section between the outflow end of the indoor heat exchanger 101 and the inflow end of the radiation heat exchanger 210, or the intermediate heat exchanger 320 is arranged on the flow pipe section between the outflow end of the radiation heat exchanger 210 and the inflow end of the indoor heat exchanger 101.

[0078] In this embodiment, the intermediate heat exchanger 320 includes 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 indoor radiation working fluid flow path, and the second heat exchange part can be connected to the external heat source pipeline to enable heat exchange between the radiation working fluid and the external heat source.

[0079] Optionally, the intermediate heat exchanger 320 is a shell and tube heat exchanger.

[0080] In some embodiments, the shell and tube heat exchanger includes an inner tube and an outer tube extending coaxially and arranged inside and outside, wherein the internal pipeline of the inner tube serves as a channel for the flow of hot working fluid for an external heat source, and the space formed between the inner wall of the outer tube and the outer wall of the inner tube serves as a channel for the flow of radiation working fluid, so that the hot working fluid and the radiation working fluid can perform non-contact indirect heat transfer in the shell and tube heat exchanger, thereby avoiding the problem of cross-contamination between the two different media, the hot working fluid and the radiation working fluid, during heat exchange.

[0081] In another embodiment, the shell and tube heat exchanger includes a first group of heat pipes and a second group of heat pipes, which are arranged in a relative position such as side by side or crosswise and are in thermal contact with each other, wherein the first group of heat pipes is connected to an indoor radiation working medium flow path, and the second group of heat pipes is connected to an external heat source, so that the radiation working medium flowing in the first group of heat pipes and the thermal working medium flowing in the second group of heat pipes can also exchange heat in the shell and tube heat exchanger.

[0082] In an embodiment, the number of indoor heat exchangers 101 is one or more, and the radiation module has the same number of radiation heat exchangers 210 as the indoor heat exchangers 101. As shown in the figure, the number of indoor heat exchangers 101 is two, and accordingly, the number of radiation heat exchangers 210 of the radiation module is also two.

[0083] In this embodiment, the indoor heat exchanger 101 is connected to the radiation heat exchanger 210 in a one-to-one correspondence and is constructed as a separate radiation branch. Each radiation branch is connected in parallel to the indoor radiation working medium circulation loop. Figure 2 Two sets of radiation branches are constructed in total, and each indoor heat exchanger 101 provides cooling / heating to its corresponding radiation heat exchanger 210 through the corresponding radiation branch. Optionally, for the air-conditioning system shown in this embodiment, the same set of indoor heat exchangers 101 and their corresponding radiation heat exchangers 210 are arranged in the same indoor area, that is, the same set of indoor heat exchangers 101 and radiation heat exchangers 210 cool / heat the same indoor area. Since each set of indoor radiation working medium circulation loop works independently, when the user turns on a certain indoor heat exchanger 101 for cooling / heating, the radiation heat exchanger 210 can be simultaneously enabled to cool / heat the same indoor area without interfering with the temperature of other indoor areas.

[0084] Each radiation branch is also provided with a radiation valve 220, which is used to individually control the on / off state of the corresponding radiation branch.

Unless explicitly required, individual components and functions are optional, and the order of operations may vary.
