Description

Technical Field

[0001] Embodiments of the present disclosure provide an air conditioning system and a temperature adjustment method. Background Art

[0002] Air conditioners cool indoor spaces, providing a comfortable environment. However, air conditioners typically consume a lot of energy, hindering energy conservation. For example, excessive air conditioning energy consumption is the primary cause of power shortages in the summer and power surpluses in other seasons, resulting in a significant waste of social resources. Another example is the compact design of automotive air conditioners, which are only about 50% as energy efficient as conventional air conditioners. This wastes significant amounts of fuel for internal combustion vehicles or electricity for electric vehicles, reducing range.

[0003] To reduce air conditioning energy consumption, especially in central air conditioning systems, management energy-saving technologies are currently being adopted. For example, frequency converters are used to adjust the power of the central air conditioning system's pumps and fans, IoT intelligent control methods are used to reduce pump and fan power, and regulating valves are used to control air and water volume to reduce cooling waste.

[0004] However, practice has shown that for a fundamentally well-designed air conditioning system, the energy savings achievable through management without compromising air conditioning temperature standards are typically less than 10%, making the investment economics less than ideal. Furthermore, the temperature drift problem of the temperature sensors used to control the equipment's frequency has long remained unreliable.

[0005] If energy savings of 15% or more are achieved through management, this often comes at the cost of significantly reduced air conditioning performance. For example, in commercial spaces, this can reduce revenue per square meter, making the energy savings insufficient to offset the reduced profit margin. Summary of the Invention

[0049] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0051] The drawings in this disclosure are not drawn strictly to scale, and the specific size and quantity of each structure can be determined according to actual needs. The drawings provided in this disclosure are only schematic diagrams.

[0052] According to an embodiment of the present disclosure, an air conditioning system is provided. Figure 1A-1F Schematic diagram of an air conditioning system according to an embodiment of the present disclosure. Figure 1A-1F As shown, the air-conditioning system according to an embodiment of the present disclosure includes: a first air-conditioning device 100A, which cools a first target area A having a first initial temperature; a second air-conditioning device 100B, which cools a second target area B having a second initial temperature; the first target area A is located outside the second target area B and at least partially surrounds the second target area B, and the first initial temperature is higher than the second initial temperature; the first air-conditioning device uses at least one of cooling water, cooling air, water from a natural water body, and natural air to cool the first target area.

[0053] It should be noted that the first initial temperature of the first target area A refers to the temperature of the first target area A before the first air-conditioning equipment 100A is used for cooling, the second initial temperature of the second target area B refers to the temperature of the second target area B before the second air-conditioning equipment 100B is used for cooling, the first initial temperature of the first target area A is higher than the second initial temperature of the second target area B, and the second initial temperature of the first target area A refers to the temperature of the first target area A is higher than the temperature of the second target area B before the first air-conditioning equipment 100A and the second air-conditioning equipment 100B are used for cooling.

[0054] It should be noted that the first air-conditioning equipment uses at least one of cooling water, cooling air, water from natural water bodies and natural air to cool the first target area, which means that any one of cooling water, cooling air, water from natural water bodies and natural air or any combination thereof is used by the first air-conditioning equipment to cool the first target area.

[0055] It should be noted that there may be various situations in which the first target area A is located outside the second target area B and at least partially surrounds the second target area B. As an example, the embodiment of the present disclosure provides the following situation; however, the embodiment of the present disclosure is not limited to the following situation.

[0056] Case 1: For example, Figure 1A and 1BAs shown, with the ground as a reference, the second target area B is located on the ground, and the first target area A is located on the side of the second target area B away from the ground. For example, in an indoor space, hot air will rise and cold air will sink, making the temperature of the upper part of the indoor space higher than that of the lower part of the indoor space. In this case, the upper part of the indoor space is the first target area A and the lower part of the indoor space is the second target area B. For example, lighting devices may be installed in the upper part of the indoor space. The lighting devices generate heat while emitting light. In particular, a large number of lighting devices may be installed in some commercial places, resulting in a large amount of heat generation. In this case, the upper part of the indoor space is the first target area A and the lower part of the indoor space is the second target area B. For example, under sunlight, the temperature of the upper part of the interior space of a building will be higher than that of the lower part. In this case, the upper part of the interior space of the building is the first target area A and the lower part of the interior space of the building is the second target area B. For example, the indoor space is a kitchen space, the interior space of a commercial place, etc. For example, under sunlight, the temperature of the roof of a building is higher than the temperature of the interior space of the building. In this case, the area where the roof of the building is located is the first target area A and the interior space of the building is the second target area B. For example, Figure 1A As shown, the first target area A and the second target area B are separated by a barrier; for example, a suspended ceiling installed in an indoor space can serve as the barrier. Figure 1B As shown, there is no barrier between the first target area A and the second target area B, so that the first target area A and the second target area B are completely connected.

[0057] Case 2: For example, Figure 1C As shown, with the ground as a reference, the second target area B is located on the ground, and the first target area A is set on the other side of the second target area B except the side close to the ground. Figure 1D As shown, the second target area B is the interior space, while the first target area A is the area surrounding the interior space. For example, due to solar radiation, the temperature of the building's exterior structure is higher than the temperature of the building's interior space. In this case, the area surrounding the building's exterior structure is the first target area A, and the building's interior space is the second target area B.

[0058] Case 3: For example, Figure 1E As shown, the first target area A is set to surround the entire second target area B. For example, due to sunlight, the temperature of the car's peripheral structure is higher than the temperature of the car's interior space. In this case, the area where the car's peripheral structure is located is the first target area A and the car's interior space is the second target area B.

[0059] Case 4, for example, Figure 1FAs shown, along the direction of heat flow, the first target area A is located upstream of the heat flow, while the second target area is located downstream of the heat flow. For example, multiple servers are set up in the computer room of a data center. During the operation of the multiple servers, a large amount of heat is generated. This heat moves in a directional manner and becomes a heat flow. During the flow of the heat flow, a temperature gradient is generated so that the temperature of the upstream area of the heat flow is higher than the temperature of the downstream area of the heat flow. At this time, the upstream area of the heat flow is the first target area A and the downstream area of the heat flow is the second target area B. For example, during the operation of multiple servers, a large amount of heat is generated and introduced into a pit under the floor of the computer room. This heat moves in a directional manner in the pit and becomes a heat flow. It should be noted that directional movement does not necessarily mean movement in only one direction. Heat can move in multiple directions to form multiple heat flows.

[0060] It should be noted that in the above Figures 1A to 1F , the connecting line between the first target area A and the first air-conditioning device 100A represents that the first air-conditioning device 100A cools the first target area A and does not represent the actual equipment pipeline; similarly, the connecting line between the second target area B and the second air-conditioning device 100B represents that the second air-conditioning device 100B cools the second target area B and does not represent the actual equipment pipeline.

[0061] It should be noted that the first initial temperature is higher than the second initial temperature, so the first target area with the first initial temperature can be called a high-heat area, and the second target area with the second initial temperature can be called a low-heat area.

[0062] According to the embodiments of the present disclosure, cooling water, cooling air, water from natural bodies, and natural air serve as natural cooling media. These natural cooling media consume little energy during refrigeration, resulting in the first air conditioning unit 100A, which utilizes a natural cooling medium, having a very high cooling efficiency (cooling efficiency = heat cooled per unit time divided by input power). For example, the cooling efficiency of the first air conditioning unit 100A, which utilizes a natural cooling medium, can reach 8-200; in comparison, the cooling efficiency of a conventional central air conditioner is only 3. Because the air conditioning system according to the embodiments of the present disclosure includes the first air conditioning unit 100A with such a high cooling efficiency, the cooling efficiency of the entire air conditioning system is very high, resulting in excellent energy savings.

[0063] According to the embodiments of the present disclosure, due to the inherent characteristics of the natural cooling medium, the first air conditioning device 100A, which uses the natural cooling medium, has excellent cooling effects on high-temperature areas. This embodiment divides the area to be cooled into a high-temperature area (i.e., the first target area A) and a low-temperature area (i.e., the second target area B) based on temperature. The first air conditioning device 100A is used to cool the high-temperature area, fully leveraging its advantages. The low-temperature area can then be cooled using the second air conditioning device 100B (e.g., a compression air conditioner), which is suitable for low-temperature areas. This results in excellent cooling effects for the entire air conditioning system.

[0064] According to an embodiment of the present disclosure, on the other hand, the first target area A is located outside the second target area B and at least partially surrounds the second target area B. Since the outer first target area A is cooled by the first air-conditioning device 100A which has an excellent cooling effect on high-temperature areas, the second target area B is less affected by the heat from the first target area A, thereby reducing the cooling load of the second air-conditioning device 100B, and further improving the cooling efficiency of the entire air-conditioning system.

[0065] According to the embodiments of the present disclosure, on the other hand, based on the various situations listed above that "the first target area A is located outside the second target area B and at least partially surrounds the second target area B", it can be seen that the air-conditioning system provided by the embodiments of the present disclosure has a very wide range of applications, that is, the embodiments of the present disclosure can achieve high cooling efficiency and good cooling effects in a large number of life and production scenarios, and have very high practical value.

[0066] The technical effects of the air conditioning system according to the embodiment of the present disclosure will be further described using an example in which the first target area A is the upper portion of the indoor space and the second target area B is the lower portion of the indoor space. Conventional technology does not divide the indoor space to be cooled according to temperature. Instead, a compression air conditioner, for example, is used to uniformly cool the indoor space. The temperature in the upper portion of the indoor space is high (e.g., due to the aforementioned air flow, lighting installation, solar radiation, and other factors). For example, the temperature in the upper portion of the indoor space can reach as high as 40-50 degrees Celsius due to heat generated by lamps. Due to design temperature limitations, the compression air conditioner has a poor cooling effect on the high-temperature upper portion of the indoor space. Furthermore, the large amount of heat in the upper portion of the indoor space also affects the cooling effect of the compression air conditioner on the lower portion of the indoor space, resulting in a high cooling load and poor cooling effect. According to an embodiment of the present disclosure, the area to be cooled is divided into a high-temperature area (e.g., the upper portion of the indoor space) and a low-temperature area (e.g., the lower portion of the indoor space) based on temperature. The upper portion of the indoor space is cooled by the first air conditioner 100A, fully leveraging the advantages of the first air conditioner 100A. The lower portion of the indoor space can then be cooled by the second air conditioner 100B (e.g., a compression air conditioner), which is suitable for low-temperature areas. This results in excellent cooling performance for the entire air conditioning system. Furthermore, the first air conditioner 100A, which uses a natural cooling medium, has very high cooling efficiency, resulting in very high cooling performance for the entire air conditioning system, achieving excellent energy savings. Furthermore, because the upper portion of the indoor space is cooled by the first air conditioner 100A, which excels in cooling high-temperature areas, the lower portion of the indoor space is less affected by heat from the upper portion, thereby reducing the cooling load of the second air conditioner 100B, further improving cooling performance and energy efficiency. Similar to the scenario where the first target area A is the upper portion of the indoor space and the second target area B is the lower portion of the indoor space, the embodiments of the present disclosure can also achieve the above-mentioned technical effects in other application scenarios.

[0067] For example, if the first initial temperature is higher than the wet-bulb temperature of the natural environment and the second initial temperature is lower than the wet-bulb temperature of the natural environment, the first air conditioning device 100A can more effectively cool the first target area A, thereby improving the cooling effect of the entire air conditioning system. Here, the natural environment refers to the natural environment in which the first target area A and the second target area B are located, such as an outdoor environment.

[0068] For example, the second air conditioner is at least one of a compression air conditioner, an absorption air conditioner, a semiconductor air conditioner, and a magnetic refrigeration air conditioner. For example, if the first initial temperature of the first target area is 5°C or more higher than the design temperature of the second air conditioner, the first air conditioner 100A can more effectively cool the first target area A, thereby improving the cooling effect of the entire air conditioning system.

[0069] Figure 2 1 is a schematic structural diagram of a first air conditioning device of an air conditioning system according to an embodiment of the present disclosure. For example, the first air conditioning device 100 includes: an air inlet 11, an air outlet 21, a first wet curtain 31, and a first fan 41. The first wet curtain 31 serves as a cooling component. Air flows from the air inlet 11 to the first wet curtain 31 under the action of the first fan 41. After passing through the first wet curtain 31, the air becomes cooled air and reaches the air outlet 21. The first water collection tray 51, a first water pump 61, a first water pipe 71, a first water collection pipe 81, and a first circulating water distributor 91 are provided. The first water collection tray 51 is located below the first wet curtain 31. Water in the first water collection tray 51 enters the first water pipe 71 under the action of the first water pump 61, passes through the first water pipe 71 and the first water collection pipe 81, and reaches the first circulating water distributor 91. The first circulating water distributor 91 sprays the first wet curtain 31 onto the first wet curtain 31, and after passing through the first wet curtain 31, the water becomes cooled water and flows back to the first water collection tray 51. Air (for example, outdoor natural air) and circulating water meet in the first wet curtain 31 and exchange air and water to achieve cooling; for example, in this process, the temperature of the air and circulating water can be reduced to a wet-bulb temperature close to that of the natural environment, that is, the cooling water and cooling air obtained after passing through the first wet curtain 31 have a wet-bulb temperature close to that of the natural environment, so as to be used for cooling purposes.

[0070] For example, Figure 2 As shown, the first fan 41 is located on a side of the first wet curtain 31 close to the air outlet 21. However, the embodiment of the present disclosure is not limited thereto, as long as the first fan 41 is located in a position that allows air to pass through the first wet curtain 31.

[0071] For example, the first wet curtain 31 has a honeycomb structure so that the air and the circulating water can fully contact each other for air-water exchange to achieve cooling. For example, the first wet curtain 31 is made of an organic material with stable performance.

[0072] For example, the circulating water in the first water collection tray 51 comes from a water source such as ordinary tap water. For example, the first water collection tray 51 is connected to a water source to replenish water lost due to heat exchange as needed. For example, the amount of water in the first water collection tray 51 can be adjusted according to actual needs.

[0073] For example, the air entering from the air inlet 11 comes from the natural environment. For example, the amount of air entering from the air inlet 11 can be adjusted according to actual needs.

[0074] Figure 3A-Figure 3E Schematic diagram of using cooling air from the first cooling device to cool the first target area. Figure 3A-Figure 3E The following description is made by taking the case where the first target area A is located on the side of the second target area B away from the ground as an example; Figure 3A-Figure 3EThis also applies to other situations where the first target area A is outside the second target area B. Figure 3A-Figure 3E In the embodiment, the cooling air of the first air-conditioning device 100A is used to cool the first target area. In this case, the cooling water of the first air-conditioning device 100A may not cool the first target area. The first water supply pipe 71 and the first water collecting pipe 81 are directly connected to each other to serve as a circulating water pipe to circulate water between the first water collecting tray 51 and the first wet curtain 31.

[0075] See also Figure 3A , the first air-conditioning device 100A also includes an air duct 21-1 in gas communication with the air outlet 21, the first target area A has an air inlet A-1 and an air outlet A-2, the air duct 21-1 is in gas communication with the air inlet A-1 of the first target area A, the cooling air enters the first target area A from the air inlet A-1 of the first target area A, and leaves the first target area A from the air outlet A-2 of the first target area A. During this process, the cooling air exchanges heat with the first target area A to cool the first target area A. The above-mentioned cooling method is to use a cooling medium such as cooling air to directly cool the first target area A, which is called open cooling. The open cooling method requires a small investment; especially when the outer structure of the building itself has an air duct (for example, the space between the external marble of the building and the outer wall), the cooling air can be directly introduced into the air duct of the outer structure of the building, which is more economical. For example, in Figure 3A In the embodiment, the first target area A may be the upper part of an indoor space, the upper part of an interior space of a building, an outer structure of a building having an air duct, and the like.

[0076] For example, see Figure 3B The first air conditioning device 100A further includes a plurality of relay fans 21-2, which are arranged in sequence from the air inlet A-1 of the first target area A to the air outlet A-2 of the first target area A, so that the cooling air flows from the air inlet A-1 of the first target area A to the air outlet A-2 of the first target area A in a directional manner, thereby improving the efficiency of heat exchange between the cooling air and the first target area A and improving the cooling effect of the first target area A. For example, the number of relay fans 21-2 can be appropriately set according to actual conditions. For example, Figure 3B In the embodiment, the first target area A may be the upper part of an indoor space, the upper part of an interior space of a building, an outer structure of a building having an air duct, and the like.

[0077] For example, see Figure 3C, the first air conditioning device 100A further includes a plurality of diffusers 21-3. When the cooling air moves from the air inlet A-1 of the first target area A to the air outlet A-2 of the first target area A, the plurality of diffusers 21-3 deliver part of the cooling air to the second target area B. For example, a barrier is provided between the first target area A and the second target area B to separate the first target area A from the second target area B. In this case, by providing the diffusers 21-3, part of the cooling air entering the first target area A can be delivered to the second target area B, thereby reducing the cooling load of the second air conditioning device 100B and improving the cooling energy efficiency of the entire air conditioning system. For example, in Figure 3C In the embodiment, the first target area A may be the upper part of an indoor space, the upper part of an interior space of a building, and the like.

[0078] For example, see Figure 3D The first air conditioning device 100A further includes a heat exchange duct 21-4, which is disposed within the first target area A. One end of the heat exchange duct 21-4 is in gaseous communication with the air inlet A-1 of the first target area, and the other end is in gaseous communication with the air outlet A-2 of the first target area A. Since one end of the heat exchange duct 21-4 is in gaseous communication with the air inlet A-1 of the first target area, the heat exchange branch pipe 21-4 is in gaseous communication with the air duct 21-1 as described above. The cooling air is passed through the air duct 21-1 into the heat exchange duct 21-4 and, while flowing through the heat exchange duct 21-4, heat exchanges with the first target area A to achieve cooling of the first target area A. For example, the heat exchange duct 21-4 is a corrugated pipe to increase the heat exchange area between the cooling air and the first target area A. The above-mentioned cooling method is that the cooling medium, such as cooling air, indirectly cools the first target area A through a heat exchanger, such as the heat exchange duct 21-4, which is called closed cooling. In the closed cooling process, there is only heat exchange but no air exchange, so it is suitable for application environments with high requirements on air quality. Figure 3C In the embodiment, the first target area A may be the upper part of an indoor space, the upper part of an interior space of a building, an upstream area of a heat flow (eg, an upstream area of a heat flow in a heat pit under a machine room floor), and the like.

[0079] For example, see Figure 3E The first air conditioning device 100A includes an air duct 21-1, one end of which is in air communication with the air outlet 21, and the other end of which has an injection port 21-5. The injection port 21-5 injects cooling air to the first target area A to cool the first target area A. Figure 3E In the process, the cooling medium such as cooling air directly cools the first target area A, so it is also open cooling. Figure 3E In the embodiment, the first target area A may be a roof of a building, an outer structure of a building, an outer structure of a car, and the like.

[0080] It should be noted that in Figures 3A-3E In the figure, only one air duct 21-1 is shown as an example; however, the embodiment of the present disclosure is not limited thereto, and multiple air ducts 21-1 can be provided that are gas-connected to the air outlet 21 respectively, and the cooling air transmitted by the multiple air ducts 21-1 acts on different parts of the first target area A to cool the first target area A at the same time.

[0081] Figures 4A-4D Schematic diagram of using cooling water of the first cooling device to cool the first target area. Figures 4A-4D The cooling water of the first air-conditioning device 100A is used to cool the first target area A; in this case, the cooling air of the first air-conditioning device 100A may not be used to cool the first target area A, and the cooling air of the first air-conditioning device 100A may be output to the natural environment through the air outlet 21.

[0082] For example, see Figure 4A The first air conditioning unit 100A includes a cooling water distributor 71-A connected to a first water pipe 71, which sprays cooling water onto a first target area A to cool the first target area A. A water collector 81-A connected to a first water collection pipe 81, which collects the water from the first target area A and delivers it to the first water collection pipe 81. The cooling water sprayed onto the first target area A undergoes heat exchange with the first target area A, thereby lowering the temperature of the first target area A and increasing the temperature of the cooling water. The water collected by the water collector 81-A is heated and transported by the first water collection pipe 81 to the first wet curtain 31 for cooling, followed by recycling. For example, the water sprayed onto the first target area A flows into the water collector 81-A under the action of gravity. For example, multiple first water pipes 71 and multiple cooling water distributors 71-A, each connected to each of the multiple first water pipes 71, can be provided to simultaneously spray cooling water onto multiple portions of the first target area A, thereby enhancing the cooling effect. For example, a plurality of first water collecting pipes 81 and a plurality of water collecting tanks 81-A respectively connected to the plurality of first water collecting pipes 81 may be provided to facilitate the recycling of circulating water and save water resources. Figure 4A In the process, the cooling water directly cools the first target area A, which is open cooling. Figure 4A In the example, the first target area A may be a building roof, a building perimeter structure, a car perimeter structure, and the like.

[0083] For example, see further Figure 4AThe first air conditioning device 100A further includes a water pump connected between the water collector 81-A and the first water collecting pipe 81 to transfer the water collected by the water collector 81-A to the first water collecting pipe 81. By providing the water pump, the water collected by the water collector 81-A can be transferred to the first water collecting pipe 81 regardless of the relative positional relationship between the water collector 81-A and the first water collecting pipe 81, thereby increasing the design flexibility of the water collector 81-A and the first water collecting pipe 81 and reducing the difficulty of equipment installation.

[0084] exist Figure 4A In the embodiment, the water collector 81-A is close to the lower part of the first target area A; however, in Figure 4B , the water collector 81-A is located near the upper portion of the first target area A. For example, see Figure 4B The water collector 81-A includes: a water collecting tank 81-A-1; a T-type sewer pipe 81-A-2, including a first end and a second end opposite to each other and a third end away from the first end and the second end, the third end being liquid-connected to the bottom of the water collecting tank 81-A-1, and the first end being liquid-connected to the first water collecting pipe 81; a limiting pipe 81-A-3, one end of the limiting pipe 81-A-3 being liquid-connected to the second end of the T-type sewer pipe 81-A-2, the other end of the limiting pipe 81-A-3 being liquid-connected to the rainwater pipe of the building, and the other end of the limiting pipe 81-A-3 being liquid-connected to the rainwater pipe of the building is closer to the water collecting tank 81-A-1 than the end of the limiting pipe 81-A-3 being liquid-connected to the second end of the T-type sewer pipe 81-A-2; and an anti-siphon port 81-A-4, which is opened at the other end of the limiting pipe 81-A-3. For example, the water collection tank 81-A-1 can be the original water collection tank of the building. In this way, there is no need to set up a water collection tank specifically for the water collector 81-A, reducing equipment costs. Under the action of the limiting pipe 81-A-3, the cooling water preferentially enters the first water collection pipe 81 for circulating cooling; when it rains (at this time, the first air-conditioning device 100A may or may not work; however, the temperature of the building's outer structure is not too high when it rains, so it is preferred that the first air-conditioning device 100A does not work when it rains), due to the continuous increase in the amount of external water, the water level of the sewer pipe 81-A-2 continues to rise. When the water level exceeds the upper limit water level of the limiting pipe 81-A-3, the water flows to the building's rainwater pipe and is eventually discharged to the municipal rainwater main. For example, the anti-siphon port 81-A-4 can prevent the building's rainwater pipe from generating a siphon effect and evacuate the water inside the first air-conditioning device 100A. For example, in Figure 4B In the example, the first target area A may be a roof of a building or a peripheral structure of a building.

[0085] For example, see Figure 4CThe first air conditioning device 100A further includes a heat exchanger 101, which is disposed in the first target area A. One end of the heat exchanger 101 is in liquid communication with the first water pipe 71, and the other end is in liquid communication with the first water collecting pipe 81. The cooling water is transported by the first water pipe 71 to the heat exchanger 101 disposed in the first target area A to perform heat exchange with the first target area A. During the heat exchange process, the temperature of the first target area A decreases while the temperature of the cooling water increases. The water with increased temperature returns to the first wet curtain 31 through the first water collecting pipe 81 for cooling, and is then recycled. Figure 4C In the example, the cooling water indirectly cools the first target area A through the heat exchanger 101, which is a closed cooling method. It can be seen that the closed cooling method is safer and the cooling water will not have an adverse effect on the electrical devices in the first target area A. For example, the heat exchanger 101 is a surface cooler. For example, in Figure 4C In the embodiment, the first target area A may be the upper part of an indoor space, the upper part of an interior space of a building, an upstream area of a heat flow (eg, an upstream area of a heat flow in a heat pit under a machine room floor), and the like.

[0086] For example, the first target area A includes a plurality of sub-areas spaced apart from each other, and the first air conditioning device 100A includes a plurality of heat exchangers, which are respectively located in the plurality of sub-areas of the first target area A. For example, see Figure 4D Taking the first target area A as the exterior structure of a car as an example, the first target area A includes multiple, spaced-apart subareas A-1 and A-2. For example, the car roof is subarea A-1, and the car hood is subarea A-2. Heat exchanger 101-1 is located in subarea A-1, while heat exchanger 101-2 is located in subarea A-2. This allows simultaneous cooling of the car roof and hood, despite their distance from each other. This allows the first air conditioning device 100A provided in the disclosed embodiment to be flexibly designed based on the specific conditions of the first target area A, thus embracing a wide range of applications.

[0087] It should be noted that in the above Figure 3A-Figure 3E The cooling air is used to cool the first target area A. Figures 4A-4D The first target area A is cooled by cooling water; however, the embodiment of the present disclosure is not limited thereto, and both cooling air and cooling water may be used to cool the first target area A. For example, the above Figure 3A-Figure 3E and its corresponding description and the above Figures 4A-4D and their corresponding descriptions.

[0088] On the top Figure 3A-Figure 3E The cooling air is introduced into the first target area A to cool the first target area A. Figures 4A-4DThe cooling water is introduced into the first target area A to cool the first target area; however, the embodiment of the present disclosure is not limited thereto, and the cooling air and cooling water may also be introduced into the first target area to achieve cooling of the first target area. Figure 5 is another structural diagram of the first air conditioning device of the air conditioning system according to an embodiment of the present disclosure. Figure 5 The first air-conditioning device 100 includes: an air inlet 11, an air outlet 21, a first wet curtain 31 and a first fan 41. The first wet curtain 31 is used as the cooling component. Under the action of the first fan 41, air reaches the first wet curtain 31 from the air inlet 11, becomes cooled air after passing through the first wet curtain 31 and reaches the air outlet 21; a first water collecting tray 51, a first water pump 61, a first circulating water pipe 102, and a first circulating water distributor 91. The water collecting tray 51 is located below the first wet curtain 31. The water in the first water collecting tray 51 reaches the first circulating water distributor 91 through the first circulating water pipe 102 under the action of the first water pump 61 and is cooled by the first circulating water distributor 91. A circulating water distributor 91 sprays water onto the first wet curtain 31. After passing through the first wet curtain 31, the water becomes cooling water and flows back to the first water collection tray 51. An isolated heat exchanger 103 is provided. A first circulating water pipe 102 is located on a first side of the isolated heat exchanger 103 and exchanges heat with the isolated heat exchanger 103. A circulating heat exchanger 104 is provided. The circulating heat exchanger 104 is located on a second side of the isolated heat exchanger 103 that is different from the first side, for example, the second side is opposite the first side. The circulating heat exchanger is filled with a cooling medium that exchanges heat with the isolated heat exchanger 103. At least a portion of the circulating heat exchanger is located in the first target area A to cool the first target area. The isolated heat exchanger 103 can serve as a medium to enable heat exchange between the first circulating water pipe 102 on its first side and the circulating heat exchanger 104 on its second side, while isolating the two to prevent material exchange between them. The cooling water reaches the isolation heat exchanger 103 through the first circulating water pipe 102, and transfers the cold energy to the isolation heat exchanger 103. The isolation heat exchanger 103 transfers the cold energy to the cooling medium in the circulating heat exchanger 104. The cooling medium in the circulating heat exchanger 104 absorbs the heat of the first target area A to cool the first target area A. The cooling medium in the circulating heat exchanger 104 transfers the heat to the isolation heat exchanger 103. The isolation heat exchanger 103 transfers the heat to the cooling water in the first circulating water pipe 102. The cooling water that has gained heat passes through the first wet curtain 31 and is cooled again, thus circulating. For example, the cooling medium in the circulating heat exchanger 104 is not cooling water or cooling air; it is a suitable cooling medium selected according to the specific situation of the first target area A. For example, Figure 5 As shown, the circulation heat exchanger 104 includes a circulation pump. For example, the entire circulation heat exchanger 104 is located in the first target area; in this case, the entire circulation heat exchanger 104 is transparent, for example. Figure 5The structure can select a suitable cooling medium according to the specific conditions of the first target area A, making the design of the first air conditioning device 100A provided by the embodiment of the present disclosure more flexible and having a wider range of applications. For example, on the front windshield of a car (for example, see Figure 4D ) also requires cooling, you can use Figure 5 In the illustrated first air conditioning system, the front windshield of the vehicle serves as sub-area A-3 of the first target area A. At least a portion of the circulating heat exchanger 104 is disposed between the two panes of glass of the vehicle's front windshield, on the inward-facing side of the vehicle's front windshield, or on the outward-facing side of the vehicle's front windshield, cooling the vehicle's front windshield using a cooling medium. In this case, for example, at least the portion of the circulating heat exchanger 104 located in the first target area A is transparent, and the cooling medium is also transparent. For example, depending on actual needs, the cooling medium may also have antifreeze properties or properties that prevent algae growth.

[0089] It should be noted that for Figure 5 The structure shown can select a suitable cooling medium according to the characteristics of the first target area A; and Figure 5 The structure shown is not only applicable to cooling the front windshield of the car as described above, but is also applicable to cooling the transparent roof, cooling the transparent outer structure of the building, and the like.

[0090] It should be noted that the portion of the circulation heat exchanger 104 located in the first target area A and the portion located outside the first target area A may be an integrated structure or a split structure.

[0091] In the above description, only one first air conditioning device 100A is shown for the first target area A; however, the embodiments of the present disclosure are not limited thereto, and multiple first air conditioning devices 100A may be provided for the first target area A according to actual needs.

[0092] Figure 6 is another structural diagram of the first air conditioning device of the air conditioning system according to an embodiment of the present disclosure. Figure 6The first air conditioning device provided in the disclosed embodiment also includes a first air filter. The first air filter includes a second wet curtain 32. Air enters the second wet curtain 32 from the air inlet 11 under the action of the first fan 41, and then reaches the first wet curtain 31 after passing through the second wet curtain 32. A second water collection tray 52, a second water pump 62, a second circulating water pipe 72, and a second circulating water distributor 92 are located below the second wet curtain 32. Water in the second water collection tray 52, under the action of the second water pump 62, flows through the second circulating water pipe 72 to the second circulating water distributor 92, where it is sprayed onto the second wet curtain 32. After passing through the second wet curtain 32, it flows back to the second water collection tray 52. The first air filter is located on the air inlet side of the first wet curtain 31 to purify the air entering the first wet curtain 31 and reduce particulate matter in the air entering the first wet curtain 31. This allows for the provision of clean air to the indoor space when the cooled air is subsequently used for open-circuit cooling. On the other hand, since the air and circulating water meet at the first wet curtain 31, the air is purified before entering the first wet curtain 31, which reduces circulating water evaporation and prevents scaling of heat exchangers and other structures caused by particulate matter or hardness components in the cooling water during cooling. The first air filter according to the embodiment of the present disclosure has a simple structure, is easy to clean, and is very effective in removing oily particles from the air.

[0093] For example, according to an embodiment of the present disclosure, the second air conditioning device 100B is at least one of a compression air conditioner, an absorption air conditioner, a semiconductor air conditioner, and a magnetic refrigeration air conditioner. Generally, the design temperature of a compression air conditioner is 26°C ± 2°C. Therefore, when a compression air conditioner is used to cool only the second target area B with low temperature, the cooling load of the compression air conditioner is not high, thereby reducing energy consumption. Figures 1A-1F The second target area B with low temperature is basically the area where people move indoors. The use of compression air conditioning can provide a comfortable indoor environment for people indoors.

[0094] For example, if the first initial temperature of the first target area is 5°C or higher than the design temperature of the second air conditioner 100B, the first air conditioner 100A can more effectively cool the first target area A, thereby improving the cooling effect of the entire air conditioning system. Typically, the design temperature of a compression air conditioner is 26°C ± 2°C, and the first initial temperature of the first target area A is 31°C or higher.

[0095] Figure 7 is a schematic diagram of the structure of the second air conditioning device of the air conditioning system according to an embodiment of the present disclosure. Figure 7The second air conditioning device 100B includes an air inlet 23B. The second air conditioning device 100B provided by the embodiment of the present disclosure also includes a second air filter. The second air filter includes: a second air inlet 13, a second air outlet 23, a third wet curtain 33, and a second fan 43. The second air outlet 23 is in gaseous communication with the air inlet 23B of the second air conditioner 100B. Under the action of the second fan 43, air flows from the second air inlet 13 to the third wet curtain 33. After passing through the third wet curtain 33, it enters the air inlet 23B of the second air conditioner 100B through the second air outlet 23. A third water collection tray 53, a third water pump 63, a third circulating water pipe 73, and a third circulating water distributor 93 are also included. The third water collection tray 53 is located below the third wet curtain 33. Under the action of the third water pump 63, water in the third water collection tray 53 flows through the third circulating water pipe 73 to the third circulating water distributor 93. The water is sprayed onto the third wet curtain 33 by the third circulating water distributor 93, and then flows back to the third water collection tray 53 after passing through the third wet curtain 33. Furthermore, for example, the second air filter is disposed on the air inlet side of the terminal heat exchanger of the second air conditioner 100B. Traditional compression air conditioners typically use dry air filters, which require frequent cleaning and are difficult to manage. This can easily lead to poor air conditioning performance and waste fan energy, especially when the incoming air contains oil. The air filter provided by the disclosed embodiments is less prone to clogging, easily automated, and effectively removes oily particles from the incoming air.

[0096] For example, according to an embodiment of the present disclosure, the first air conditioning device 100A includes a water pump that inputs water from a natural water body into the first target area A to cool the first target area A. For example, water from a natural water body includes groundwater and surface water. Generally, the water temperature of a natural water body is similar to the local annual average temperature. For example, the method in which the first air conditioning device 100A uses water from a natural water body to cool the first target area A can refer to Figures 4A-4D , water from the natural water body is input into the water pipe 71 through the water pump, and the water collecting pipe 81 returns the water with a higher temperature after heat exchange with the first target area A to the natural water body; in this case, the water intake point where the water pump takes water from the natural water body and the return point where the water collecting pipe 81 returns water to the natural water body are separated by a certain distance to prevent the water after heat exchange from affecting the temperature of the water input into the water pipe 71, thereby affecting the cooling effect. For example, the method of using water from the natural water body to cool the first target area by the first air conditioning equipment 100A can refer to Figure 5 The water pump inputs water from the natural water body into the first circulating water pipe 102 , and after heat exchange with the isolation heat exchanger 103 , the water in the first circulating water pipe 102 is discharged and returned to the natural water body, for example.

[0097] For example, in summer, water from a natural water body is used to cool the first target area A. For example, in winter, the water from a natural water body is used to cool the first target area A. Figure 2 The cooling water described cools the first target area A.

[0098] It is understandable that when the water from the natural water body and the above-mentioned cooling water are used to cool the first target area A simultaneously, a water delivery pipe 71 and a water collecting pipe 81 can be provided for the water from the natural water body and the above-mentioned cooling water respectively.

[0099] For example, the first air conditioning device 100A includes a fan that inputs natural air into the first target area A to cool the first target area A. For example, the natural air is outdoor air. The method of using natural air to cool the first target area A can refer to Figure 3A-Figure 3E Under the action of the fan, natural air is input into the air duct 21 - 1 and then input into the first target area A, or under the action of the fan, natural air is directly input into the first target area A.

[0100] It is understandable that when natural air and the cooling air are used to cool the first target area A simultaneously, air ducts 21 - 1 may be provided for the natural air and the cooling air, respectively.

[0101] For example, according to an embodiment of the present disclosure, the first air-conditioning device 100A can also heat the first target area A having a third initial temperature, and the second air-conditioning device 100B can also heat the second target area B having a fourth initial temperature, the third initial temperature is lower than the fourth initial temperature, and the first air-conditioning device 100A uses groundwater to heat the first target area A. In this case, the first target area A is a low-heat area, and the second target area B is a high-heat area. For example, in winter, the temperature of the outer structure of a building is lower than the temperature of the interior space of the building, and the temperature of the outer structure of a car is lower than the temperature of the interior space of the car. For example, in winter, the temperature of groundwater is higher, and it can be used to heat the first target area; in this case, the heating efficiency of the entire air-conditioning system can be improved and a good heating effect can be obtained. For example, the way in which the first air-conditioning device 100A uses groundwater to heat the first target area A can refer to Figures 4A-4D , groundwater is pumped into the water pipe 71, and the water collecting pipe 81 returns the water whose temperature has dropped after heat exchange with the first target area A to the groundwater; in this case, the water intake point of the water pump and the return point of the water collecting pipe 81 are separated by a certain distance to prevent the water after heat exchange from affecting the temperature of the water input to the water pipe 71, thereby affecting the heating effect. For example, the method of using groundwater to cool the first target area by the first air conditioning equipment 100A can refer to Figure 5 The water pump inputs the groundwater into the first circulating water pipe 102. After heat exchange with the isolation heat exchanger 103, the water in the first circulating water pipe 102 is discharged and returned to the natural water body, for example.

[0102] It should be noted that the third initial temperature of the first target area A refers to the temperature of the first target area A before the first air-conditioning equipment 100A is used for heating, the fourth initial temperature of the second target area B refers to the temperature of the second target area B before the second air-conditioning equipment 100B is used for heating, the third initial temperature of the first target area A is lower than the fourth initial temperature of the second target area B, which means that the temperature of the first target area A is lower than the temperature of the second target area B before the first air-conditioning equipment 100A and the second air-conditioning equipment 100B are used for heating.

[0103] For example, if the third initial temperature is 5°C or more lower than the design temperature of the second air conditioner, the first air conditioner 100A has a better heating effect.
