Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning system and a control method thereof. Background Art

[0002] The air conditioning system includes an all-air system, which is a system that completely uses air to bear the cold and heat load of the room. The all-air air conditioning system provides sensible heat and latent heat to the room by delivering cold air, or delivers hot air to the room to provide heat. Therefore, an air handling device is required in the all-air system to process the delivered air. The air handling device must have a heat exchanger for heat exchange between liquid and air. Since the heat exchanger is a heat exchanger for heat exchange between liquid and air, its volume is relatively large compared to the heat exchanger for heat exchange between liquid and liquid. This is due to the specific heat capacity. The cooling capacity / heating capacity per unit volume of air is much smaller than that of liquid. For example, the cooling capacity / heating capacity per unit volume of air is only about one thousandth of that of water, and the difference between the two is close to 3 orders of magnitude. Therefore, the volume of the air handling device in the current all-air system is generally large, and generally requires an independent equipment room for storage, which makes it impossible to popularize it in ordinary houses with limited area and number of rooms.

[0003] If the size of the air handling device is reduced, the air flow rate is reduced, and no other terminal equipment or measures are added, it can be installed in an ordinary residence, but the ability of the air handling device to supply cold or hot air to the room will become limited. For example, when a user enters the room and turns on the air conditioner and needs to immediately adjust the temperature in the room to the user's set temperature, the air handling device and the air supply terminal of the room cannot meet the needs at this time, and it cannot adjust the temperature in the room to the user's set temperature in a short time. Therefore, a new air conditioning system is urgently needed and its layout is optimized to better meet the needs of users. Summary of the invention

[0072] The technical solution of the present invention has the following significant beneficial effects:

[0073] 1. When the user just enters the first space and turns on the air conditioning system to quickly adjust the temperature and / or humidity of the first space, the air conditioning system can use the first heat exchange unit to form gas after temperature and / or humidity adjustment and input the gas into the first space through the air supply terminal, so as to achieve temperature and / or humidity adjustment of the first space. At the same time, the energy supply device also supplies heat and / or cold to the terminal device, so that the terminal device can quickly process the gas in the second space, such as temperature adjustment and / or humidity adjustment. Since the first space is connected to the second space, when the temperature and / or humidity of the second space are also adjusted, the temperature and / or humidity of the second space can approach or reach the parameters set by the user, so that the gas that may enter the first space from the second space can play a favorable role in adjusting the temperature and / or humidity of the first space, so that the parameters of the gas in the first space can be adjusted to the parameters set by the user more quickly.

[0074] 2. Since the first heat exchange unit in the air handling device adjusts the temperature and / or humidity of the gas flowing into the fresh air inlet and / or the return air inlet and flowing out of the air supply outlet, the gas is then transported to the air supply terminal to enter the first space. Since the cooling / heating capacity of air is relatively low, at the same volume flow rate, it is basically only about one thousandth of that of liquid, so the gas input into the first space cannot carry the full power of the energy supply device. Therefore, when it is necessary to achieve rapid temperature adjustment and / or humidity adjustment for the first space, the remaining power of the energy supply device can be allocated to the terminal device, and the terminal device is used to adjust the parameters of the gas in the second space, thereby further shortening the time for the gas parameters in the first space to be adjusted to the parameters set by the user. In this way, the performance of the energy supply device can be fully utilized to achieve rapid temperature adjustment and / or humidity adjustment for the first space.

[0075] 3. The air-conditioning system in the present application can combine the advantages of various systems such as the full air handling system, the radiant air-conditioning system and the multi-split system. The air-conditioning system can use the terminal equipment to adjust the temperature and / or humidity of the space, so it has the advantages of taking up less space and being easy to install. The air-conditioning system can continuously introduce fresh air to regulate the freshness of the air in the space, and can form a better airflow organization through the reasonable arrangement of the air supply terminal and the terminal equipment, thereby forming a relatively uniform and stable temperature, humidity, airflow speed and cleanliness in one space or multiple spaces to meet the comfort requirements of the human body. In addition, the air-conditioning system has the advantages of low noise and high comfort during operation.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0092] In order to fully utilize the performance of the energy supply device in the air-conditioning system to achieve rapid temperature adjustment and / or humidity adjustment for the first space, an air-conditioning system is proposed in the present application. Figure 1 FIG. 1 is a schematic diagram of the principle of the air conditioning system in the first embodiment of the present invention. Figure 2 FIG. 1 is a schematic diagram showing the principle of the air conditioning system in the second embodiment of the present invention. Figure 1 and Figure 2 As shown, the air conditioning system includes: an air treatment device 800 , at least one air supply terminal 300 , at least one terminal device 400 and an energy supply device 600 .

[0093] Among them, Figure 1 and Figure 2 As shown, the air handling device 800 may include: a return air port 2, an air supply port 3, a fresh air port 4; a first heat exchange unit 6, the first heat exchange unit 6 having a first heat exchange channel 61, the first heat exchange channel 61 can adjust the temperature and / or humidity of the gas flowing into the fresh air port 4 and / or the return air port 2 and flowing out of the air supply port 3. The above-mentioned gas may include air.

[0094] like Figure 1 and Figure 2 As shown, the air supply terminal 300 can be connected to the air supply port 3 to receive the conditioned gas output by the air supply port 3. At least one air supply terminal 300 can be used to supply air to the first space 100. Further, at least one air supply terminal 300 can be used to supply air to the second space 200.

[0095] like Figure 1 and Figure 2 As shown, at least one terminal device 400 is used to process the gas in the second space 200, and the first space 100 is connected to the second space 200. For example, the connection can be made through an open door or a door gap. The energy supply device 600 can be used to supply heat and / or cold to the first heat exchange flow channel 61 and the terminal device 400, so that the terminal device 400 can process the gas in the second space 200, and the first heat exchange unit 6 can adjust the gas flowing out of the air supply port 3 to supply air to the first space 100, and the temperature and / or humidity of the gas in the first space 100 is adjusted.

[0096] When the user just enters the first space 100 and turns on the air conditioning system to quickly adjust the temperature and / or humidity of the first space 100, the air conditioning system can use the first heat exchange unit 6 to form the gas after the temperature and / or humidity adjustment is completed and input the gas into the first space 100 through the air supply terminal 300, so as to achieve the temperature and / or humidity adjustment of the first space 100. At the same time, the energy supply device 600 also supplies heat and / or cold to the terminal device 400, so that the terminal device 400 can quickly process the gas in the second space 200, such as temperature adjustment and / or humidity adjustment. Since the first space 100 is connected to the second space 200, when the temperature and / or humidity of the second space 200 are also adjusted, the temperature and / or humidity of the second space 200 can approach or reach the parameters set by the user, so that the gas that may enter the first space 100 from the second space 200 can play a favorable role in adjusting the temperature and / or humidity of the first space 100, so that the parameters of the gas in the first space 100 can be adjusted to the parameters set by the user more quickly. In addition, since the first heat exchange unit 6 in the air handling device 800 adjusts the temperature and / or humidity of the gas flowing into the fresh air inlet 4 and / or the return air inlet 2 and flowing out of the air supply port 3, and then delivers the gas to the air supply terminal 300 to enter the first space 100. Since the cooling capacity / heating capacity of air is relatively low, at the same volume flow rate, it is basically only about one thousandth of that of liquid, so the gas input into the first space 100 cannot carry the full power of the energy supply device 600, so when it is necessary to achieve rapid temperature adjustment and / or humidity adjustment for the first space 100, the remaining power of the energy supply device 600 can be allocated to the terminal device 400, and the terminal device 400 is used to adjust the parameters of the gas in the second space 200, thereby further shortening the time for the gas parameters in the first space 100 to be adjusted to the parameters set by the user. In the above manner, the performance of the energy supply device 600 can be fully utilized to achieve rapid temperature adjustment and / or humidity adjustment for the first space 100.

[0097] As a feasible method, the return air outlet 2 of the air treatment device 800 can be connected to the second space 200 and the first space 100. For example, the return air outlet 2 of the air treatment device 800 is indirectly connected to the first space 100 through the second space 200, and the specific air flow path is as follows: the gas in the second space 200 enters the return air outlet 2 of the air treatment device 800, and the gas is then supplied by the air supply outlet 3 after being processed by the air treatment device 800, and then enters the first space 100 through the air supply terminal 300, and part of the gas in the first space 100 enters the second space 200, and the cycle continues in this way. Through the above-mentioned method, the return air requirement of the first space 100 is guaranteed, and the installation of the air-conditioning system can be made more convenient. The first space 100 does not need to install a pipe with a certain length for return air to the return air outlet 2 of the air treatment device. As a feasible method, the return air outlet 2 of the air treatment device 800 can be directly connected to the second space 200 and the first space 100 through the return air pipe at the same time. Further, as Figure 1 and Figure 2 As shown, the return air port 2 of the air handling device 800 may only be directly connected to the second space 200 .

[0098] When the air handling device 800 forms the temperature-adjusted and / or humidity-adjusted gas using the first heat exchange unit 6 and inputs the gas into the first space 100 through the air supply terminal 300, the gas in the second space 200 will enter the return air port 2. Since it is necessary to achieve rapid temperature adjustment and / or humidity adjustment for the first space 100, the terminal device 400 will adjust the gas in the second space 200 accordingly, and the parameters of the gas in the second space 200 entering the return air port 2 will be close to the parameters set by the user, so that the air handling device 800 can supply a higher flow of conditioned gas to the first space 100, thereby accelerating the adjustment of the gas in the first space 100 to the parameters set by the user.

[0099] The energy supply device 600 may include a compressor and a heat exchange system. Figure 1 As shown, the compressor and the heat exchange system are used to supply the cooled or heated refrigerant to the terminal device 400 and the first heat exchange channel 61; or Figure 2 As shown, the compressor and heat exchange system are used to supply the cooled or heated refrigerant to the first heat exchange channel 61, and to supply heat or cold to the terminal device 400. For example, the compressor and heat exchange system can be a heat pump outdoor unit, an air conditioner outdoor unit, etc.

[0100] When the air conditioning system is installed in an ordinary residential building, such as a flat house, the first space 100 may be a quiet space, which needs to be relatively quiet at certain times, for example, a bedroom, a study, etc., where the air conditioning system is not expected to generate relatively loud noise when adjusting the temperature and / or humidity. The second space 200 may be a moving space, where people move relatively frequently, for example, a dining room, a living room, etc., where the air conditioning system may generate relatively loud noise when adjusting the temperature and / or humidity, which may not have much impact.

[0101] Since there are multiple spaces of different types in ordinary houses, such as bedrooms, dining rooms, and living rooms, these different types of spaces have very different requirements for temperature regulation and / or humidity regulation, such as the speed and noise during temperature regulation and / or humidity regulation, the freshness of the air in the space, etc., the full air system cannot meet the different requirements of different types of spaces only through the air supply terminal. Since the performance characteristics of the air supply terminal 300 in the air conditioning system for air treatment of the first space 100 are different from the performance characteristics of the terminal device 400 in the air conditioning system for air treatment of the second space 200, the different performance characteristics of the air supply terminal 300 and the terminal device 400 can be used to meet the demand differences between the first space 100 and the second space 200 due to different types, so as to better meet the needs of users during use and improve the user experience. For example, at some times, the quiet space is relatively closed and cannot be directly ventilated with the outdoors, so the air conditioning system needs to add fresh air. By conditioning the air in the first space 100 through the air supply terminal 300, the above requirements can be better met. The air supply terminal 300 can make a relatively small sound when it is blowing out air, and it can also replenish fresh air. For example, the bedroom can still ensure the freshness and quietness of the air in the first space 100 when the user is sleeping at night. The second space 200 has a relatively large area or a large temperature difference from the parameters set by the user, and the air conditioning system needs to provide a large cooling capacity or heating capacity. By conditioning the air in the second space 200 through the terminal device 400, the above requirements can be better met. Relatively speaking, the cooling capacity or heating capacity provided by the terminal device 400 per unit time is large, which can meet the requirements of the second space 200, and the relatively large noise it emits will not have a significant impact on the users of the space. In addition, the general users of the second space 200 often ventilate and exchange air. Therefore, when the air conditioning system adjusts the temperature and / or humidity, even if fresh air is not replenished, it will not cause a significant impact. The general users have low requirements in this regard.

[0102] As feasible, Figure 1As shown, the inlet and outlet of the terminal device 400 can be connected to the outlet and inlet of the energy supply device 600 respectively, and the energy supply device 600 delivers the refrigerant to the terminal device 400 and recycles it. The inlet and outlet of the first heat exchange flow channel 61 can be connected to the outlet and inlet of the energy supply device 600 respectively. For example, Figure 1 As shown, the terminal device 400 and the first heat exchange channel 61 can be connected to the compressor and the heat exchange system in parallel, and the refrigerant input from the compressor and the heat exchange system to the terminal device 400 and the first heat exchange channel 61 can be distributed by the fluid distribution unit. In another feasible embodiment, the two ends of the terminal device 400 and the first heat exchange channel 61 after being connected in series can be connected to the compressor and the heat exchange system. In other feasible embodiments, the energy supply device 600 may include two compressors and heat exchange systems, and the two ends of the terminal device 400 can be connected to one compressor and heat exchange system respectively, and the two ends of the first heat exchange channel 61 can be connected to the other compressor and heat exchange system respectively.

[0103] In the above-mentioned embodiments, the terminal device 400 connected to the outlet and the inlet of the energy supply device 600 may include an indoor unit of an air conditioner.

[0104] The study found that no matter how the heat exchanger for heat exchange between liquid and air is optimized, the size of the heat exchanger can only be reduced slightly at most. Due to the large air flow rate, the heat exchanger cannot be further reduced to the ideal size. Therefore, the size of the air treatment device 800 cannot be reduced to the ideal size. The room temperature cannot be further miniaturized by only relying on the air delivered to the room. Therefore, after changing the idea, it is found that a heat exchange unit for heat exchange between liquid and liquid can be set in the air treatment device 800. Since the heat exchange performance of the heat exchange unit for heat exchange between liquid and liquid is far superior to the heat exchange performance of the first heat exchange unit 6 for heat exchange between liquid and air, the liquid can be used to exchange heat with the air in the room to provide cold or heat to the room. It should be noted that the heat exchange unit for heat exchange between liquid and liquid here can be a heat exchange unit for heat exchange between gas and liquid in two phases. In extreme cases, it can also be a heat exchange unit in which the refrigerant is completely throttled to gas state and the gaseous refrigerant exchanges heat with the liquid.

[0105] Therefore, as feasible, Figure 2As shown, the air treatment device 800 may include: a second heat exchange unit 5, the second heat exchange unit 5 having a second heat exchange channel 51 and a third heat exchange channel 52 capable of heat exchange. The energy supply device 600 is used to supply heat and / or cold to the second heat exchange channel 51 and the first heat exchange channel 61. At least one terminal device 400 can be connected to the third heat exchange channel 52. The second heat exchange unit 5 is a heat exchanger for liquid to liquid heat exchange. By miniaturizing the size of the air treatment device 800 to an ideal degree, the air treatment device 800 can be directly installed in an ordinary commercial residence, such as a kitchen or balcony, etc.

[0106] Figure 7 This is a schematic diagram of the structure when the air supply module is located at the upper end of the air handling device. Figure 8 is a schematic diagram of the structure when the air supply module is located at the lower end of the air handling device, such as Figure 2 , Figure 7 and Figure 8 As shown, the air handling device 800 may include: a shell 1 having a return air outlet 2, a supply air outlet 3, and a fresh air outlet 4, and a second heat exchange unit 5 and a first heat exchange unit 6 are arranged in the shell 1. The fresh air outlet 4 is used to communicate with the outdoor air through a fresh air duct, so as to replenish fresh air. The supply air outlet 3 is used to connect to the air supply terminal 300 through the air supply duct. The air supply terminal 300 can be one or more, which can be located in different spaces, so as to achieve temperature regulation and / or humidity regulation for different spaces. The return air outlet 2 and the fresh air outlet 4 can be independent openings, or they can share the same opening. The fresh air and the return air are first mixed and then sent into the shell 1 through one opening.

[0107] As feasible, the return air inlet 2, the supply air inlet 3, and the fresh air inlet 4 can be independently arranged on the shell 1, or at least partially arranged inside or outside the shell 1, and only one or two openings need to be formed on the shell 1. For example, a pipe body whose interior is divided into two or three independent flow channels can be passed through the shell 1, so as to be connected to at least two of the return air inlet 2, the supply air inlet 3, and the fresh air inlet 4 inside or outside the shell 1. For another example, the return air inlet 2 and the fresh air inlet 4 are connected to a pipeline through a pipeline and then communicated with the inside of the shell 1 through an opening on the shell 1.

[0108] As a feasibility, the air supply duct can be made of metal material, which can effectively reduce the resistance to the gas.

[0109] like Figure 7 and Figure 8As shown, a gas flow channel is formed in the housing 1, and the return air port 2 and the fresh air port 4 are connected to the air supply port 3 through the gas flow channel, and the gas flow channel passes through the first heat exchange unit 6. Therefore, when the air flows through the gas flow channel and is discharged from the air supply port 3, the temperature and / or humidity can be adjusted by the first heat exchange unit 6. The fresh air port 4 is connected to the outdoor air through the fresh air duct.

[0110] As feasible, the air conditioning system includes: at least one filter element, which is used to filter the gas discharged from the air supply port 3. For example, the filter element can be set in the fresh air duct and / or the gas flow channel. The filter element may include one of the following: HEPA, PP melt-blown material, etc. The structure and shape of the filter element may correspond to the first heat exchange unit 6, so that the filter element can be installed together with the first heat exchange unit 6 or arranged in the same direction, and the air flowing through the first heat exchange unit 6 is immediately filtered by the filter element, or the air flowing through the filter element immediately flows through the first heat exchange unit 6. The above method can also avoid the increase in the volume of the air treatment device 800. For example, the cross-section of at least part of the first heat exchange unit 6 can be V-shaped or arc-shaped, and correspondingly, the cross-section of at least part of the filter element is V-shaped or arc-shaped, so that the filter element can be installed together with the first heat exchange unit 6 or arranged in the same direction.

[0111] As feasible, Figure 7 and Figure 8 As shown, the air treatment device 800 may include: a booster device 20. The booster device 20 may be disposed in the housing 1 and connected between the first inlet end and the first outlet end. The booster device 20 is used to drive the heat exchange medium in the third heat exchange channel 52 of the second heat exchange unit 5 to flow toward the terminal device 400, and then flow back to the third heat exchange channel 52.

[0112] In a feasible embodiment, the air treatment device 800 may include: a fan disposed in the housing 1, the fan is used to transport the gas flowing into the return air port 2 and / or the fresh air port 4 to the air supply port 3. Afterwards, the gas output from the air supply port 3 can enter the first space 100 to be transported from the air supply terminal 300 through the air supply duct. By controlling the power of the fan, the air supply volume can be controlled to a certain extent. In this embodiment, the fan and the housing 1 are arranged together.

[0113] In another possible implementation, if Figure 7 and Figure 8 As shown, the air treatment device 800 may include: an air supply module 19. The air supply module 19 includes a housing and a second fan disposed in the housing. The air supply module 19 is disposed separately from the housing 1, and the air supply module 19 and the housing 1 can be installed together so that the inlet of the air supply module 19 is connected to the air supply port 3 of the housing 1. For example, Figure 7 As shown, the air outlet 3 of the housing 1 is located at the top plate of the housing 1, and the air supply module 19 is at least partially installed in the ceiling. This method can be particularly used for the method of using the air supply duct in the ceiling to supply air. In addition, it can also improve the aesthetics of the air treatment device 800, and the air supply module 19 that generates noise is at least partially installed in the ceiling to reduce the impact of noise on users. For another example, Figure 8 As shown, the air outlet 3 of the housing 1 is located at the bottom plate of the housing 1, and the air supply module 19 is at least partially used to be installed on the floor. This method can be particularly aimed at the method of using the air supply duct under the floor to supply air.

[0114] As feasible, the fan can form gas at a preset pressure, and the preset pressure is greater than or equal to 200 Pa. Through high-pressure air supply, under the condition of the same air supply volume, the diameter of the air supply duct at least in part can be greatly reduced, which can facilitate the drilling of holes when the air supply duct passes through walls and beams, so that the air handling device 800 is easy to install in ordinary residential buildings, such as single-story houses, which is conducive to the laying of air supply ducts. For example, the air supply duct needs to be laid from the kitchen or balcony to the bedroom and living room, etc., which generally needs to pass through walls and beams. Some walls or beams have steel bars. Once the diameter of the air supply duct at this location is reduced, it is easy to avoid the steel bars when drilling holes, and there is no need to cut the steel bars, which is conducive to protecting the strength structure of the building.

[0115] The air treatment device 800 may include: Figure 1 and Figure 2 As shown, a first air valve 8 for adjusting the return air volume of the return air outlet 2 and / or a second air valve 9 for adjusting the fresh air volume of the fresh air outlet 4. By adjusting the opening of the first air valve 8 and / or the second air valve 9, the ratio between the return air volume and the fresh air volume can be adjusted.

[0116] As a feasible method, the air outlet 3 can output air of a first preset temperature, and the difference between the user-set temperature and the first preset temperature is greater than or equal to 13 degrees Celsius. By further reducing the temperature of the air output from the air outlet 3, under the same other conditions, the amount of air supplied to the first space 100 can be reduced, which can further reduce the diameter of the air supply duct, facilitate the laying of the air supply duct, and also miniaturize the air treatment device 800 to a certain extent.

[0117] As feasible, the air supply port 3 is connected to the air supply terminal 300 through an air supply duct, and the air supply duct includes an air supply duct main pipe and an air supply duct branch pipe connected to the air supply duct main pipe, and the diameter of at least part of the air supply duct main pipe is less than or equal to 130 mm. Further, the diameter of at least part of the air supply duct branch pipe is less than or equal to 100 mm. The above goal can be achieved by high-speed and low-temperature air supply, which can greatly facilitate the laying of the air supply duct, and finally realize that the air conditioning system can be installed in ordinary residential flats.

[0118] As feasible, Fig. 9 Schematic diagram of the structure of the wind box body in the embodiment of the present invention. Figure 1 and Figure 2 , Fig. 9 As shown, the air conditioning system may include: an air distribution box 500. The inlet of the air distribution box 500 is connected to the air supply port 3 of the air treatment device 800, and the air distribution box 500 has multiple outlets, and at least part of the outlets of the air distribution box 500 are provided with air valves. The treated gas output from the air supply port 3 of the air treatment device 800 can be diverted by the air distribution box 500 to be respectively delivered to the air supply terminals 300 in different spaces through different air supply ducts. The air flow rate of the gas delivered to the air supply terminal 300 corresponding to the air valve can be controlled by the air valve. When the fan is arranged in the housing 1, the inlet of the air distribution box 500 can be connected to the air supply port 3 on the housing 1. When the air treatment device 800 includes an air supply module 19, the inlet of the air distribution box 500 can be connected to the outlet of the air supply module 19. The air distribution box 500 can be installed in the ceiling, thereby improving the aesthetics of the air treatment device 800.

[0119] As feasible, Fig. 9 As shown, the air volume detection device 5001 may be provided in the air distribution box 500, and the air volume detection device 5001 is used to detect the air volume output from the outlet of the air distribution box 500. The air treatment device 800 may include: a controller with an air volume display function, and the controller may be installed in the corresponding space. The controller is electrically connected to the air volume detection device 5001 or can realize wireless communication, and the controller is used to display the air volume output from the outlet of the air distribution box 500 detected by the air volume detection device 5001. The user can not only control the air treatment device 800 through the controller to change the user-set temperature of the space, but also directly know the air volume input to the space by the air treatment device 800 at this time. Further, the controller may also have a temperature control function, and the user may operate the controller to control the air conditioning system. The controller can communicate with the air volume detection device 5001 through a power carrier, so there is no need to install additional communication lines.

[0120] As a feasible method, the air supply terminal 300 can adopt an air supply box structure, which can have a muffler function, thereby reducing the decibel of the sound it emits to enhance the user experience. The air supply terminal 300 can also be directly the end of the air supply duct. Further, the air supply terminal 300 can be connected to the outlet of the air distribution box 500 through the air supply duct.

[0121] As a feasible method, the second heat exchange unit 5 can adopt a plate heat exchanger, a shell and tube heat exchanger, etc. Of course, other types of heat exchangers can also be used in the present application, and no limitation is made to the specific type of the second heat exchange unit 5. Further, the second heat exchange unit 5 can preferably adopt a plate heat exchanger. Relatively speaking, the heat exchange performance of the plate heat exchanger is better, and its volume can be smaller under the same heat exchange amount. As a feasible method, the first heat exchange unit 6 can include a heat exchanger with fins. Through the above structure, the heat exchange amount of the heat exchanger can be increased to improve the heat exchange performance, thereby miniaturizing the air treatment device 800.

[0122] The two ends of the third heat exchange channel 52 can be connected to the terminal device 400 respectively. At least one terminal device 400 is a device capable of adjusting the temperature and / or humidity of the gas in the second space 200, and the terminal device 400 for processing the gas in the second space 200 includes at least one of the following: a fan coil unit and a chilled beam. The terminal device 400 can be one or more. A circulation channel can be formed between the third heat exchange channel 52 and the terminal device 400 for adjusting the temperature and / or humidity of the gas in the second space 200, and the circulation channel uses a heat exchange medium to achieve heat transfer. Generally speaking, the heat exchange medium can be a liquid substance with high thermal conductivity and high cooling capacity, such as water, which has a relatively low cost and is easy to replace or supplement at will. Since the cooling capacity of the heat exchange medium is much greater than the cooling capacity of the air, the terminal device 400 such as a fan coil unit and a chilled beam can achieve rapid adjustment of the gas in the second space 200.

[0123] As feasible, Figure 2As shown, at least one terminal device 400 can be a device capable of adjusting the temperature and / or humidity of the gas in the first space 100, and the terminal device 400 for processing the gas in the first space 100 includes at least one of the following: floor heating, wall heating, and capillary network. Similarly, as feasible, at least one terminal device 400 can be a device capable of adjusting the temperature and / or humidity of the gas in the second space 200, and the terminal device 400 for processing the gas in the second space 200 includes at least one of the following: floor heating, wall heating, and capillary network. In the above embodiment, the device for adjusting the temperature and / or humidity of the gas in the first space 100 and the second space 200 has the characteristic of slow onset, and cannot complete the temperature and / or humidity adjustment in a short time, but has the advantage of being quiet and not generating any noise. For example, if the gas in the first space 100 needs to be maintained at a temperature or humidity set by the user, and if you want the first space 100 to be sufficiently quiet and noise-free, it can be achieved through the terminal device 400 in the above embodiment. In addition, when the first space 100 needs to be quickly adjusted to the temperature or humidity set by the user, the distribution terminal and the terminal device 400 for processing the gas in the first space 100 can be operated simultaneously to fully utilize the performance of the energy supply device 600 and the air treatment device 800.

[0124] When the user needs to cool down the first space 100 faster, the air treatment device 800 can use the first heat exchange unit 6 to cool the air, and then directly input the cooled air into the first space 100 through the air supply port 3 and the air supply terminal 300, so that the first space 100 can achieve a faster cooling speed. Although the cooling speed of the second heat exchange unit 5 and the terminal device 400 is slow, the second heat exchange unit 5 and the terminal device 400 can be used to cool down the first space 100 at the same time, so that the cooling speed of the first space 100 can be further accelerated under the premise of fully utilizing the performance of the air treatment device 800, so as to approach or meet the user's demand for rapid cooling of the space.

[0125] As feasible, Figure 2 As shown, the terminal device 400 for processing the gas in the second space 200 and the terminal device 400 for processing the gas in the first space 100 can be connected together in parallel.

[0126] As feasible, the energy supply device 600 may include: a compressor and a heat exchange system. Figure 2 FIG. 1 is a schematic diagram showing the principle of the air conditioning system in the second embodiment of the present invention. Figure 3 for Figure 2The schematic diagram of the second heat exchange flow channel and the first heat exchange flow channel in the air conditioning system in the first embodiment is as follows Figure 2 and Figure 3 As shown, the second heat exchange channel 51 and the first heat exchange channel 61 can be connected to the compressor and the heat exchange system in parallel. The air treatment device 800 may include: a fluid distribution unit, which is used to distribute the heat exchange medium input to the second heat exchange channel 51 and the first heat exchange channel 61 by the compressor and the heat exchange system. The refrigerant input by the compressor and the heat exchange system can be distributed to the second heat exchange channel 51 and the first heat exchange channel 61 according to specific needs through the fluid distribution unit.

[0127] For example, the air handling device 800 may include at least a first working state and a second working state: in the first working state, the fluid distribution unit delivers all the heat exchange medium input by the compressor and the heat exchange system to the first heat exchange channel 61 of the first heat exchange unit 6. At this time, the temperature and / or humidity of the space are adjusted by the air supply terminal 300, and the terminal device 400 connected to the third heat exchange channel 52 is in a non-operating state. The second working state is particularly important in the following situation. When the difference between the surface temperature of the terminal device 400 for adjusting the temperature of the first space 100 and the dew point temperature of the first space 100 is less than or equal to a preset value, such as 2 degrees Celsius or about 2 degrees Celsius, at this time, if the temperature of the first space 100 is adjusted by the terminal device 400, condensation water will be formed on the surface of the terminal device 400, or condensation water will be formed on the wall and the ground in contact with the surface of the terminal device 400, and the condensation water will cause problems such as slippery ground and moldy walls, and the user experience is poor. Therefore, in this case, the second working state can be operated to avoid the above situation.

[0128] In the second working state, the fluid distribution unit delivers part of the heat exchange medium input by the compressor and the heat exchange system to the first heat exchange channel 61 of the first heat exchange unit 6, and delivers part of the heat exchange medium input by the compressor and the heat exchange system to the second heat exchange channel 51 of the second heat exchange unit 5. At this time, the temperature and / or humidity of the first space 100 can be adjusted through the air supply terminal 300, and at the same time, the terminal device 400 connected to the third heat exchange channel 52 of the second heat exchange unit 5 is in operation to achieve temperature adjustment and / or humidity adjustment of the first space 100, and / or, to achieve temperature adjustment and / or humidity adjustment of the second space 200. For example, when the temperature of the first space 100 is adjusted by the terminal device 400, condensation water will not be formed on the surface of the terminal device 400, or condensation water will not be formed on the wall and the ground in contact with the surface of the terminal device 400, the second working state can be operated. For another example, when the temperature and / or humidity of the first space 100 needs to be adjusted quickly, the second working state can be operated, and the temperature and / or humidity of the first space 100 can be adjusted through the air supply terminal 300, and the temperature and / or humidity of the second space 200 can be adjusted through the terminal device 400 such as a fan coil unit and a chilled beam for adjusting the temperature and / or humidity of the second space 200, so that the parameters of the gas in the first space 100 can be adjusted to the parameters set by the user more quickly. For another example, when the temperature and / or humidity of the first space 100 is adjusted through the air supply terminal 300, and at least one of the terminal device 400 such as a fan coil unit and a chilled beam for adjusting the temperature and / or humidity of the second space 200, the terminal device 400 such as a floor heating, a wall heating, a capillary network for adjusting the temperature and / or humidity of the second space 200, and the terminal device 400 such as a floor heating, a wall heating, a capillary network for adjusting the temperature and / or humidity of the first space 100 needs to be operated, the second working state can be operated.

[0129] Furthermore, the air conditioning system may include a control unit. The control unit is used to receive environmental information and control the air handling device 800 to be in the first working state or the second working state according to the environmental information; the environmental information includes at least one of the following: temperature information, humidity information of the space where the terminal device 400 is located, and the surface temperature of the terminal device 400. Through the above structure, the air conditioning system can control the working state according to the environmental information received by the control unit, so as to avoid the formation of condensed water on the surface of the terminal device 400 in the first working state, or the formation of condensed water on the wall and the ground in contact with the surface of the terminal device 400.

[0130] As feasible, the air handling device 800 includes at least a third working state: in the third working state, the fluid distribution unit delivers all the heat exchange medium input by the compressor and the heat exchange system to the second heat exchange flow channel 51 of the second heat exchange unit 5. At this time, the temperature and / or humidity of the first space 100 can be adjusted without using the air supply terminal 300, and at least one terminal device 400 connected to the third heat exchange flow channel 52 of the second heat exchange unit 5 is in operation to achieve temperature adjustment and / or humidity adjustment of the space. Further, in this working state, when the terminal device 400 includes at least one of the following: floor heating, wall heating, capillary network, etc., since the air supply terminal 300 does not supply air and there is no other fan device that needs to blow air, when the air treatment device 800 is in this working state, the device will not produce any sound for the space that needs temperature adjustment and / or humidity adjustment, so that it will not affect the users in the space at all. For example, when the user sleeps at night, the air treatment device 800 can be in this operating state, which can ensure the user's sleep quality on the one hand, and on the other hand, the first space 100 has a low requirement for heat exchange at night, and the requirement for heat exchange can be fully met by relying solely on the terminal device 400. Of course, in this working state, a certain amount of fresh air can also be supplied to the first space 100 through the air supply terminal 300, thereby ensuring the air quality of the first space 100. The supplied fresh air may be subjected to temperature and / or humidity adjustment processing, or may not be subjected to processing. Since the volume of the supplied fresh air is relatively small, the sound generated by the air supply terminal 300 is very small and basically does not affect the users in the first space 100.

[0131] As feasible, Figure 2 and Figure 3 As shown, the fluid distribution unit may include a first flow regulating valve 11 and a second flow regulating valve 12, the outlet of the compressor and the heat exchange system is connected to the inlet of the compressor and the heat exchange system through the first flow channel 14, the first flow channel 14 includes a second heat exchange flow channel 51, the outlet of the compressor and the heat exchange system is connected to the inlet of the compressor and the heat exchange system through the second flow channel 16, the second flow channel 16 includes a first heat exchange flow channel 61, the first flow channel 14 and the second flow channel 16 are connected in parallel, the first flow regulating valve 11 is located on the first flow channel 14, and the second flow regulating valve 12 is located on the second flow channel 16.

[0132] Through the above structure, the heat exchange medium input to the second heat exchange channel 51 and the first heat exchange channel 61 by the compressor and the heat exchange system can be distributed according to the opening of the first flow regulating valve 11 and the second flow regulating valve 12. Furthermore, the first flow regulating valve 11 and the second flow regulating valve 12 can use electronic expansion valves, which can not only realize the distribution of the heat exchange medium input to the second heat exchange channel 51 and the first heat exchange channel 61 by the compressor and the heat exchange system, but also play the role of throttling and reducing pressure. In addition, the first flow regulating valve 11 can be used without throttling, and the second flow regulating valve 12 can be used for throttling, so as to realize the isothermal dehumidification function of a certain space or multiple spaces by using the terminal device 400 and the air supply terminal 300.

[0133] In another embodiment, Figure 4 FIG. 1 is a schematic diagram of the second heat exchange channel and the first heat exchange channel in a second implementation manner in an embodiment of the present invention. Figure 4 As shown, the two ends of the second heat exchange channel 51 and the first heat exchange channel 61 after being connected in series are connected to the compressor and the heat exchange system. In this embodiment, an electronic expansion valve 21 needs to be set at the inlet of the second heat exchange channel 51 and the first heat exchange channel 61. By controlling the electronic expansion valve 21, it is realized whether the imported heat exchange medium entering the second heat exchange channel 51 and the first heat exchange channel 61 is throttled and depressurized. If the corresponding heat exchange channel needs to exchange heat, the electronic expansion valve 21 at the inlet of the heat exchange channel is controlled to play a throttling and depressurizing function on the heat exchange medium flowing through. Specifically, according to the amount of heat exchange required, the degree to which the electronic expansion valve 21 plays a throttling and depressurizing role on the heat exchange medium flowing through is controlled. In the above manner, the cooling capacity can also be distributed to the second heat exchange channel 51 and the first heat exchange channel 61. Similarly, the electronic expansion valve 21 upstream of the second heat exchange channel 51 can be throttled without throttling, and the electronic expansion valve 21 between the second heat exchange channel 51 and the first heat exchange channel 61 can be throttled, thereby utilizing the terminal device 400 and the air supply terminal 300 to achieve an isothermal dehumidification function in a certain space or multiple spaces.

[0134] In yet another embodiment, Figure 5 FIG. 1 is a schematic diagram of the second heat exchange channel and the first heat exchange channel in a third implementation manner in an embodiment of the present invention. Figure 5As shown, the energy supply device 600 includes: two compressors and heat exchange systems, the two ends of the second heat exchange channel 51 can be connected to one compressor and heat exchange system respectively, and the two ends of the first heat exchange channel 61 can be connected to another compressor and heat exchange system respectively. In this structure, a set of compressors and heat exchange systems are used to provide the second heat exchange channel 51 with a cooling or heating refrigerant, and another set of compressors and heat exchange systems are used to provide the first heat exchange channel 61 with a cooling or heating refrigerant. The terminal device 400 can transfer heat to the space; the cooling refrigerant passes through the first heat exchange channel 61 to cool and dehumidify the gas flowing through it, and the gas after cooling and dehumidification is input into the same space through the air supply port 3 and the air supply terminal 300. The cooling gas is neutralized with the heat input by the terminal device 400, so that the basic temperature of the gas in the space can be maintained, but its humidity is effectively reduced, thereby realizing the isothermal dehumidification function.

[0135] In other feasible embodiments, the air handling device 800 may include: a compressor and a heat exchange system disposed in the housing 1, the compressor and the heat exchange system being used to supply the cooled or heated refrigerant to the second heat exchange channel 51 and the first heat exchange channel 61. In this embodiment, the compressor and the heat exchange system are both installed in the housing 1 to form a complete device, and the air handling device 800 does not need to be used in conjunction with a heat pump outdoor unit.

[0136] In other possible implementations, Figure 6 FIG. 4 is a schematic diagram of the second heat exchange channel and the first heat exchange channel in a fourth embodiment of the present invention. Figure 6As shown, the energy supply device 600 includes: a compressor and a heat exchange system, one end of the compressor and the heat exchange system is connected to the first on-off valve 13 and then connected to the other end of the compressor and the heat exchange system through the first flow channel 14, the first flow channel 14 includes a second heat exchange flow channel 51 and a second on-off valve 15 connected to the other end, one end of the compressor and the heat exchange system is connected to the first on-off valve 13 and then connected to the other end of the compressor and the heat exchange system through the second flow channel 16, the second flow channel 16 includes a first heat exchange flow channel 61, the first flow channel 14 and the second flow channel 16 are connected in parallel, the first flow channel 14 has a first flow regulating valve 11, and the second flow channel 16 has a second flow regulating valve 12; one end of the compressor and the heat exchange system is connected to the first flow channel 14 between the second on-off valve 15 and the second heat exchange flow channel 51 through the third flow channel 17, and the third flow channel 17 has a third on-off valve 18. The first flow regulating valve 11 and the second flow regulating valve 12 can be electronic expansion valves, which can also achieve the purpose of throttling. By controlling the on and off of the first on-off valve 13, the second on-off valve 15 and the third on-off valve 18, the second heat exchange channel 51 and the first heat exchange channel 61 can be connected in parallel. Specifically, the first on-off valve 13 and the second on-off valve 15 are in an open state, and the third on-off valve 18 is in a closed state. At this time, the heat exchange medium input to the second heat exchange channel 51 and the first heat exchange channel 61 by the compressor and the heat exchange system can be distributed through the first flow regulating valve 11 and the second flow regulating valve 12. In this embodiment, the second heat exchange channel 51 and the first heat exchange channel 61 can also be connected in series. Specifically, the first on-off valve 13 and the second on-off valve 15 are in a closed state, and the third on-off valve 18 is in an open state. When the second heat exchange channel 51 and the first heat exchange channel 61 are connected in series, it is necessary to distribute the heat exchange medium input to the second heat exchange channel 51 and the first heat exchange channel 61 by the compressor and the heat exchange system. An electronic expansion valve is required in the compressor and the heat exchange system or on the third channel 17. The electronic expansion valve is located upstream of the second heat exchange channel 51. The refrigerant enters the second heat exchange channel 51 after passing through the electronic expansion valve and the third channel 17, and then enters the first heat exchange channel 61 after passing through the first flow regulating valve 11 and the second flow regulating valve 12 and then returns to the compressor and the heat exchange system.When the second heat exchange channel 51 and the first heat exchange channel 61 are connected in series, the isothermal dehumidification function can be realized for the same space. The liquid refrigerant with a higher temperature output by the compressor and the heat exchange system passes through the second heat exchange channel 51, and the terminal device 400 can output heat to the space at this time; thereafter, the liquid refrigerant with a higher temperature passes through the electronic expansion valves of the first flow control valve 11 and the second flow control valve 12 to be throttled and cooled to at least partially become a gaseous state, and the cooled refrigerant passes through the first heat exchange channel 61 to cool and dehumidify the gas passing through it, and the cooled and dehumidified gas is input into the above-mentioned same space through the air supply port 3 and the air supply terminal 300, and the cooled gas is neutralized with the heat input by the terminal device 400, so that the basic temperature of the gas in the space can be maintained, but its humidity is effectively reduced, thereby realizing the isothermal dehumidification function.

[0137] As feasible, Figure 2 As shown, the air conditioning system may include: a heating device 700, the inlet and outlet of the heating device 700 can be respectively connected to the flow channel between the outlet of the third heat exchange channel 52 and the terminal device 400, or the fluid flowing out of the outlet of the third heat exchange channel 52 can exchange heat with the fluid flowing out of the outlet of the heating device 700 and then supply it to the terminal device 400. The heating device 700 can be a gas water heater, a wall-mounted boiler or an electric heater, etc. For example, when the weather temperature is low, the heating performance of the compressor and the heat exchange system is limited, and the heat exchange medium flowing through the third heat exchange channel 52 of the second heat exchange unit 5 cannot be heated to a higher temperature, or the energy consumption of heating the heat exchange medium flowing through the third heat exchange channel 52 of the second heat exchange unit 5 to a higher temperature is relatively high. At this time, the heat exchange medium can be further heated by the heating device 700, so as to ensure that the heat exchange medium can still be heated to an ideal temperature, and it is more economical.

[0138] As a feasible method, the air conditioning system may include a first state, in which the first heat exchange unit 6 delivers the gas after cooling and dehumidification to the first space 100 through the air supply terminal 300, and the heating device 700 is in a heating state to increase the temperature of the first space 100 through the terminal device 400. In this embodiment, the compressor and the heat exchange system are in a cooling state, and the fluid distribution unit delivers all the cold heat exchange medium input by the compressor and the heat exchange system to the first heat exchange channel 61 of the first heat exchange unit 6, so that the air treatment device 800 delivers the gas after cooling and dehumidification to the first space 100 through the air supply terminal 300. At this time, the heating device 700 is in a heating state, thereby heating the heat exchange medium flowing through the third heat exchange channel 52 of the second heat exchange unit 5, and then the first space 100 can be heated through the terminal device 400, and finally the constant temperature dehumidification of the first space 100 is achieved.

[0139] The air conditioning system in this application can combine the advantages of the full air handling system and the multi-split system. The air conditioning system can use the terminal equipment to adjust the temperature and / or humidity of the space, so it has the advantages of less space occupation and easy installation of the system; the air conditioning system can continuously introduce fresh air to adjust the freshness of the air in the space, and can form a better airflow organization through the reasonable arrangement of the air supply terminal and the terminal equipment, so as to form a relatively uniform and stable temperature, humidity, airflow speed and cleanliness in one space or multiple spaces to meet the requirements of human comfort; in addition, the air conditioning system has the advantages of low noise and high comfort during operation. A control method for the air conditioning system is also proposed in this application, and the control method includes the following steps:

[0140] S101 : Detecting the temperature of the first space 100 .

[0141] S102: When the temperature of the first space 100 meets the first preset condition, the first heat exchange unit 6 of the air treatment device 800 is used to adjust the temperature and / or humidity of the gas delivered to the air supply terminal 300, so that the air supply terminal 300 performs temperature adjustment and / or humidity adjustment on the first space 100, and at the same time, the second heat exchange unit 5 of the air treatment device 800 is used to adjust the temperature and / or humidity of the fluid delivered to the terminal device 400, so that the terminal device 400 performs temperature adjustment and / or humidity adjustment on the second space 200; the first space 100 is connected to the second space 200.

[0142] Fig.10 FIG. 1 is a schematic diagram of a process in which the temperature in the first space is gradually adjusted to a parameter set by a user when the first preset condition is met in a feasible implementation manner, such as Fig.10 As shown, the order of steps of the control method of the air conditioning system can be Fig.10 The differences in can also be the same. Fig.10 The purpose is only to show the process of adjusting the temperature in the first space to the parameters set by the user through all the steps in the control method after the temperature in the first space meets the first preset condition. In the actual process, the control method of the air-conditioning system can be to detect the temperature of the first space 100 and then perform any one or several steps from S102 to S106 in any order. In the above steps, the first preset condition can be that the temperature of the first space 100 is greatly different from the temperature set for the first space 100, so the temperature in the first space 100 needs to be lowered quickly, for example, when the user just enters the first space 100 and just turns on the air-conditioning system to cool down the first space 100.

[0143] In the above steps, the terminal device 400 for processing the gas in the second space 200 includes at least one of the following: fan coil unit, chilled beam, air conditioner indoor unit, etc. Since the cooling capacity of air is relatively low, at the same flow rate, it is basically only about one thousandth of liquid, so the gas input into the first space 100 cannot carry the full power of the energy supply device 600, so the heat or heat generated by the energy supply device 600 can be transmitted to the terminal device 400 through the liquid working medium, and then the terminal device 400 is used to adjust the parameters of the gas in the second space 200, thereby further shortening the time for the gas parameters in the first space 100 to be adjusted to the parameters set by the user.

[0144] As a feasible condition, the first preset condition may be that the difference between the temperature of the first space 100 and the temperature set for the first space 100 is greater than or equal to a first preset value. The first preset value may be a specific value, such as 2 degrees Celsius, 3 degrees Celsius, 4 degrees Celsius, etc.

[0145] Since the first space 100 is connected to the second space 200, when the temperature and / or humidity of the second space 200 are also adjusted, the gas that may enter the first space 100 from the second space 200 can be close to the parameters set by the user, which can reduce the impact of the gas in the second space 200 on the gas in the first space 100, so that the parameters of the gas in the first space 100 can be adjusted to the parameters set by the user more quickly.

[0146] As feasible, the control method may include the following steps:

[0147] S103: When the temperature of the first space 100 does not meet the first preset condition, the first heat exchange unit 6 of the air treatment device 800 is used to adjust the temperature and / or humidity of the gas delivered to the air supply terminal 300, so that the air supply terminal 300 performs temperature adjustment and / or humidity adjustment on the first space 100; when there is no need for temperature adjustment and humidity adjustment in the second space 200, the terminal device 400 stops adjusting the temperature and humidity of the second space 200.

[0148] In the above steps, the temperature of the first space 100 is not much different from the temperature set in the first space 100, so there is no need to quickly reduce the temperature in the first space 100. At this time, there is no need to use the terminal device 400 to adjust the temperature and humidity of the second space 200, for example Fig.10 shown.

[0149] S104: When the temperature of the first space 100 satisfies the second preset condition and the dew point temperature of the first space 100 satisfies the third preset condition, the first heat exchange unit 6 of the air treatment device 800 is used to adjust the temperature and / or humidity of the gas delivered to the air supply terminal 300, so that the air supply terminal 300 performs temperature adjustment and / or humidity adjustment on the first space 100, and at the same time, the second heat exchange unit 5 of the air treatment device 800 is used to adjust the temperature of the fluid delivered to the terminal device 400, so that the terminal device 400 performs temperature adjustment on the first space 100; when there is no need for temperature adjustment and humidity adjustment in the second space 200, the terminal device 400 stops adjusting the temperature and humidity of the second space 200.

[0150] In the above steps, the terminal device 400 for adjusting the temperature of the first space 100 includes at least one of the following: floor heating, wall heating, capillary network, etc. When the dew point temperature of the first space 100 meets the third preset condition, when this type of terminal device 400 adjusts the temperature of the first space 100, condensation water will not form on the surface of the terminal device 400, or condensation water will not form on the wall and the ground in contact with the surface of the terminal device 400, thereby avoiding problems such as slippery ground and moldy walls caused by condensation water, resulting in poor user experience.

[0151] In the above steps, the second preset condition may be that the difference between the temperature of the first space 100 and the temperature set for the first space 100 is less than the first preset value and greater than or equal to the second preset value, and the second preset value is less than the first preset value. The third preset condition may be that the difference between the surface temperature of the terminal device 400 for adjusting the temperature of the first space 100 and the dew point temperature of the first space 100 is less than or equal to the third preset value. For example, the third preset value may be 2 degrees Celsius or about 2 degrees Celsius.

[0152] Through the above steps, the terminal device 400 and the air supply terminal 300 can be used to simultaneously adjust the temperature and humidity of the first space 100. For example, when the user needs to cool down the first space 100, the air treatment device 800 can use the first heat exchange unit 6 to cool the air, and then directly input the cooled air into the first space 100 through the air supply port 3 and the air supply terminal 300, so that the temperature of the first space 100 can be adjusted. Although the speed of adjusting the temperature by the cooperation of the second heat exchange unit 5 and the terminal device 400 is slow, the second heat exchange unit 5 and the terminal device 400 can be used to adjust the temperature of the first space 100 at the same time, so that the cooling speed of the first space 100 can be further accelerated under the premise of fully utilizing the performance of the air treatment device 800 and the energy supply device 600, thereby meeting the user's requirements for the cooling speed of the space.

[0153] As feasible, the control method may include the following steps:

[0154] S105: When the temperature of the first space 100 satisfies the fourth preset condition and the dew point temperature of the first space 100 satisfies the third preset condition, stop using the air supply terminal 300 to adjust the temperature and / or humidity of the first space 100, and use the second heat exchange unit 5 of the air treatment device 800 to adjust the temperature of the fluid sent to the terminal device 400, so that the terminal device 400 adjusts the temperature of the first space 100.

[0155] In the above steps, the third preset condition may be that the difference between the surface temperature of the terminal device 400 for adjusting the temperature of the first space 100 and the dew point temperature of the first space 100 is less than or equal to the third preset value. The fourth preset condition may be that the absolute value of the temperature set for the first space 100 and the temperature of the first space 100 is less than or equal to the fourth preset value, and the fourth preset value is less than the second preset value.

[0156] In this step, it can be understood that the temperature of the first space 100 is slightly different from the set temperature of the first space 100, or is about to be close, and only a small load adjustment is required to achieve the temperature of the first space 100 reaching the set temperature of the first space 100. Therefore, the temperature of the first space 100 can be adjusted by only the terminal device 400, which not only meets the demand for temperature adjustment of the first space 100, but also allows the first space 100 to be sufficiently quiet without noise, such as better meeting the user's demand for a quiet environment when sleeping at night.

[0157] As feasible, the control method may include the following steps:

[0158] S106: When the temperature of the first space 100 satisfies the fourth preset condition and the dew point temperature of the first space 100 satisfies the third preset condition, the fresh air inlet 4 of the air treatment device 800 is opened, and the return air inlet 2 of the air treatment device 800 is closed, and the gas flowing in from the fresh air inlet 4 is sent into the first space 100 through the air supply terminal 300, and the second heat exchange unit 5 of the air treatment device 800 is used to adjust the temperature of the fluid sent to the terminal device 400, so that the terminal device 400 adjusts the temperature of the first space 100.

[0159] In this step, the difference from S105 is that a small amount of fresh air is added to the first space 100 through the air treatment device 800 at the same time, so that the freshness of the air in the first space 100 can be ensured, and at the same time, the adjustment of the small load can achieve the temperature of the first space 100 reaching the set temperature of the first space 100. The flow rate of fresh air added to the first space 100 by the air treatment device 800 is small, and it is necessary to meet the influence of the flow rate of fresh air added to the first space 100 by the air treatment device 800 on the temperature of the first space 100 and the influence of the temperature adjustment of the first space 100 by the terminal device 400 on the temperature of the first space 100. The temperature of the first space 100 can still meet the fourth preset condition for a long time. Since only a small amount of fresh air is added to the first space 100 by the air treatment device 800, the air supply terminal 300 basically does not make any sound.

[0160] As a feasible method, the control method may include the following steps: detecting the air volume output from the outlet of the air distribution box 500 by the air volume detection device, and displaying the air volume output from the outlet of the air distribution box 500 detected by the air volume detection device 5001 by the controller. Through this step, the controller and the air volume detection device 5001 can cooperate to display the air volume output from the outlet of the air distribution box 500, and the user can know the air volume input by the air treatment device 800 to the space corresponding to the controller at this time through the controller.

[0161] As a feasible method, the control method may include the following steps: controlling the opening of the air valve at the outlet of the air distribution box 500 corresponding to the different air supply terminals 300 based on the air volume required to be output by different air supply terminals 300. Through this step, the air conditioning system can control the opening of the air valve at the outlet of the air distribution box 500 corresponding to the air supply terminal 300 in the user's space according to the user's needs, so that the air volume output by the air supply terminal 300 in the user's space matches the user's needs.
