Description

Air conditioning system

Technical Field

Embodiments of the present disclosure provide an air conditioning system.

Background

The air conditioner can cool an indoor environment to provide a comfortable indoor environment for a user. However, the energy consumption of the air conditioner is generally high, which is not favorable for energy saving. For example, excessive energy consumption of the air conditioner is a main cause of power supply shortage in summer and power supply surplus in other seasons, and considerable waste of social resources is caused. For another example, because the automobile air conditioner adopts a compact design, the energy efficiency is only about 50% of that of a common air conditioner, a large amount of internal combustion engine fuel or electric quantity of the electric automobile is wasted, and the endurance mileage is compressed.

In order to reduce the energy consumption of air conditioners, particularly the energy consumption of central air conditioning systems, management energy-saving technology is mainly adopted. For example, the power of a water pump and a fan of a central air-conditioning system is adjusted by using a frequency converter, or the power of the water pump and the fan is reduced by using an intelligent control means of the internet of things, or the air quantity and the water quantity are controlled by using an adjusting valve, so that the waste of cold quantity is reduced.

However, practice has proved that for an air conditioning system with a basically reasonable design, the achievable power saving rate of managing energy saving is usually less than 10% without lowering the air conditioning temperature standard, and the investment economy is not ideal. Moreover, the temperature drift problem of temperature sensors for controlling the frequency of the device has not been reliably solved for a long time.

If management of energy savings achieves a power savings rate of 15% or more, it is common practice to trade off significant reductions in air conditioning effectiveness. For example, the profit margin may be reduced in a business, so that the electricity saving profit is not enough to compensate for the loss due to the reduced profit margin.

An air conditioning system is provided according to an embodiment of the present disclosure. Fig. 1A-1F are schematic diagrams of an air conditioning system according to an embodiment of the present disclosure. As shown in fig. 1A to 1F, an air conditioning system according to an embodiment of the present disclosure includes: a first air conditioner 100A cooling a first target area a having a first initial temperature; a second air conditioner 100B cooling a second target zone B having a second initial temperature; the first target area a is located outside 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 unit uses at least one of cooling water, cooling air, water of a natural water body, and natural air for cooling the first target area.

It should be noted that the first initial temperature of the first target area a is the temperature of the first target area a before cooling by the first air conditioner 100A, the second initial temperature of the second target area B is the temperature of the second target area B before cooling by the second air conditioner 100B, and 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 first initial temperature of the first target area a is higher than the temperature of the second target area B before cooling by the first air conditioner 100A and the second air conditioner 100B.

It should be noted that, the first air conditioning device uses at least one of cooling water, cooling air, water of natural water body and natural air for cooling the first target area, which means that any one or any combination of cooling water, cooling air, water of natural water body and natural air is used by the first air conditioning device for cooling the first target area.

It should be noted that the first target area a is located outside the second target area B and at least partially surrounds the second target area B, and there may be various situations. As an example, the disclosed embodiments provide the following; however, the embodiments of the present disclosure are not limited to the following cases.

The first condition is as follows: for example, as shown in fig. 1A and 1B, the second target area B is located on the ground with reference to 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 the indoor space, the hot air may rise upward and the cold air may sink downward such that the temperature of the upper portion of the indoor space is higher than that of the lower portion of the indoor space, where the upper portion of the indoor space is the first target area a and the lower portion of the indoor space is the second target area B. For example, a lighting device may be installed in an upper portion of an indoor space, and the lighting device may emit light while generating heat, and particularly, a large number of lighting devices may be installed in some commercial locations to generate a large amount of heat, in which case the upper portion of the indoor space is a first target area a and the lower portion of the indoor space is a second target area B. For example, the temperature of the upper portion of the building interior space is higher than the temperature of the lower portion under solar radiation, where the upper portion of the building interior space is the first target area a and the lower portion of the building interior space is the second target area B. For example, the indoor space is a kitchen space, a business space, and the like. For example, the temperature of the roof of a building under solar radiation is higher than the temperature of the interior space of the building, where the area of the roof of the building is the first target area a and the interior space of the building is the second target area B. For example, as shown in fig. 1A, a first target area a is separated from a second target area B by a barrier; for example, a ceiling installed in an indoor space may serve as the barrier. For example, as shown in fig. 1B, the first target area a and the second target area B do not have any barrier between them such that the first target area a and the second target area B are fully connected.

Case two: for example, as shown in fig. 1C, the second target area B is located on the ground with reference to the ground, and the first target area a is disposed on the other side of the second target area B than the side close to the ground. Further, for example, as shown in fig. 1D, the second target area B is an inner space, and the first target area a is an area where a peripheral structure of the inner space is located. For example, due to the irradiation of the sun, the temperature of the peripheral structure of the building is higher than the temperature of the internal space of the building, where the area in which the peripheral structure of the building is located is the first target area a and the internal space of the building is the second target area B.

Case three: for example, as shown in fig. 1E, the first target area a is disposed so as to surround the entire second target area B. For example, the temperature of the peripheral structure of the vehicle is higher than the temperature of the interior space of the vehicle due to the irradiation of the sun, in which case the area in which the peripheral structure of the vehicle is located is the first target area a and the interior space of the vehicle is the second target area B.

In case four, for example, as shown in FIG. 1F, the first target area A is located upstream of the heat flow and the second target area is located downstream of the heat flow in the direction of flow of the heat flow. For example, a plurality of servers are arranged in a data center room, and generate a large amount of heat during operation, the heat moves directionally to become a heat flow, and the heat flow generates a temperature gradient during flowing so that the temperature of a heat flow upstream area is higher than that of a heat flow downstream area, and then the heat flow upstream area is a first target area a and the heat flow downstream area is a second target area B. For example, a plurality of servers generate a large amount of heat during operation that is directed into a pit below the floor of the machine room, where the heat moves directionally into a heat flux. It should be noted that the directional movement is not necessarily only along one direction, and the heat may be directionally moved along multiple directions to form multiple heat flows respectively.

Note that, in fig. 1A to 1F described above, a connection line between the first target area a and the first air conditioner 100A represents that the first air conditioner 100A cools the first target area a and does not represent an actual equipment line; similarly, the connection line between the second target zone B and the first ac unit 100B represents the second ac unit 100B cooling the second target zone B and not the actual unit lines.

It should be noted that the first initial temperature is higher than the second initial temperature, so the first target region with the first initial temperature may be referred to as a high heat region, and the second target region with the second initial temperature may be referred to as a low heat region.

According to the embodiment of the present disclosure, on the one hand, the cooling water, the cooling air, the water of the natural water body, and the natural air are natural cooling mediums, and the energy consumed in the process of cooling by using the natural cooling mediums is small, so that the first air conditioner 100A using the natural cooling mediums has a very high cooling efficiency (cooling efficiency ═ heat cooled per unit time ÷ input power). For example, the cooling efficiency of the first air conditioner 100A using a natural cooling medium may reach 8 to 200; in contrast, the cooling efficiency of the conventional central air conditioner is only 3. Since the air conditioning system according to the embodiment of the present disclosure includes the first air conditioning device 100A having a very high cooling efficiency, the cooling efficiency of the entire air conditioning system is made very high, and a very good energy saving effect can be obtained.

According to the embodiment of the present disclosure, on the other hand, the first air-conditioning apparatus 100A employing the natural cooling medium is excellent in the cooling effect on the high heat region due to the characteristics of the natural cooling medium itself. According to the embodiment of the disclosure, the area to be cooled is divided into a high-heat area (i.e., a first target area a) and a low-heat area (i.e., a second target area B) according to the temperature, the first air conditioning equipment 100A is adopted for cooling in the high-heat area, so that the advantages of the first air conditioning equipment 100A are fully exerted, and the second air conditioning equipment 100B (e.g., a compression air conditioner) suitable for the low-heat area can be adopted for cooling in the low-heat area. Therefore, the refrigerating effect of the whole air conditioning system is very good.

According to the 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, and since the outside first target area a is cooled by the first air conditioner 100A having an excellent cooling effect on the high heat area, the influence of the heat from the first target area a on the second target area B is reduced, so that the cooling load of the second air conditioner 100B is reduced, and the cooling efficiency of the whole air conditioning system is further improved.

According to the embodiments of the present disclosure, based on the above-listed situations 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 application range, that is, the embodiments of the present disclosure can achieve high cooling efficiency and good cooling effect in a large number of life and production scenes, and has a very high practical value.

The technical effects of the air conditioning system according to the embodiment of the present disclosure will be further explained by taking the first target area a as an upper portion of the indoor space and the second target area B as a lower portion of the indoor space as an example. In the conventional technology, the indoor space to be refrigerated is not divided according to the temperature, but the indoor space is refrigerated uniformly by adopting, for example, a compression type air conditioner; the temperature of the upper part of the indoor space is high (e.g. due to air flow, lighting installation, sun exposure, etc. as described above), e.g. up to 40-50 degrees under the effect of heat generated by the lamp; the compression type air conditioner has poor refrigeration effect on the upper part of the high-heat indoor space due to the limitation of the design temperature, and a large amount of heat on the upper part of the indoor space can also influence the refrigeration effect of the compression type air conditioner on the lower part of the indoor space, so that the refrigeration load is high and the refrigeration effect is poor. According to the embodiment of the disclosure, the area to be cooled is divided into a high-heat area (e.g., upper part of the indoor space) and a low-heat area (e.g., lower part of the indoor space) according to the temperature, the first air conditioning equipment 100A is adopted for the upper part of the indoor space to perform cooling, so that the advantages of the first air conditioning equipment 100A are fully exerted, the second air conditioning equipment 100B (e.g., compression type air conditioner) suitable for the low-heat area can be adopted for the lower part of the indoor space to perform cooling, and the cooling effect of the whole air conditioning system is very good; further, the first air conditioning equipment 100A using a natural cooling medium has a very high cooling efficiency, so that the cooling efficiency of the entire air conditioning system is very high, and a very good energy saving effect can be obtained; further, since the upper portion of the indoor space is cooled by the first air conditioner 100A, which is excellent in cooling effect for a high heat region, the influence of heat from the upper portion of the indoor space on the lower portion of the indoor space is reduced, thereby reducing the cooling load of the second air conditioner 100B, further improving the cooling effect and improving the energy efficiency. Similar to the case where the first target area a is the upper part of the indoor space and the second target area B is the lower part of the indoor space, the embodiments of the present disclosure can achieve the above technical effects in other application scenarios.

For example, 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, in which case the first air conditioning apparatus 100A can cool the first target area a more effectively, improving the cooling effect of the entire air conditioning system. Here, the natural environment refers to a natural environment in which the first target area a and the second target area B are located, and is, for example, an outdoor environment.

For example, the second air conditioning equipment is at least one of a compression type air conditioner, an absorption type air conditioner, a semiconductor air conditioner, and a magnetic refrigeration air conditioner. For example, the first initial temperature of the first target area is higher than the design temperature of the second air conditioner by 5 ℃ or more, in which case the first air conditioner 100A can cool the first target area a more efficiently, improving the cooling effect of the entire air conditioning system.

Fig. 2 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 conditioner 100 includes: the air conditioner comprises an air inlet 11, an air outlet 21, a first wet curtain 31 and a first fan 41, wherein the first wet curtain 31 is used as a cooling component, air reaches the first wet curtain 31 from the air inlet 11 under the action of the first fan 41, and after passing through the first wet curtain 31, the air becomes cooling air and reaches the air outlet 21; the first water collecting tray 51 is positioned below the first wet curtain 31, water in the first water collecting tray 51 enters the first water pipe 71 under the action of the first water pump 61, reaches the first water circulating distributor 91 through the first water pipe 71 and the first water collecting pipe 81, is sprayed on the first wet curtain 31 by the first water circulating distributor 91, passes through the first wet curtain 31, becomes cooling water, and returns to the first water collecting tray 51. Air (for example, outdoor natural air) meets the circulating water in the first wet curtain 31 and carries out air and water exchange, so that the temperature is reduced; for example, in this process, the temperatures of the air and the circulating water can be respectively lowered to near the wet bulb temperature of the natural environment, that is, the cooling water and the cooling air obtained through the first wet curtain 31 have near the wet bulb temperature of the natural environment for cooling purposes.

For example, as shown in fig. 2, the first fan 41 is located on a side of the first wet curtain 31 near the air outlet 21. However, the disclosed embodiment is not limited thereto as long as the first fan 41 is disposed at a position such that air passes through the first wet curtain 31.

For example, the first wet curtain 31 has a honeycomb structure so that air and circulating water can sufficiently contact each other for gas and water exchange, thereby achieving temperature reduction. For example, the first wet curtain 31 is made of an organic material having stable properties.

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

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.

Fig. 3A-3E are schematic diagrams of cooling a first target area with cooling air from a first cooling device. In fig. 3A to 3E, a case where the first target area a is located on a side of the second target area B away from the ground is described as an example; fig. 3A-3E are also applicable to other situations where the first target area a is located outside the second target area B. It should be noted that, in fig. 3A to 3E, the first target area is cooled using the cooling air of the first air conditioner 100A, in which case the cooling water of the first air conditioner 100A may not cool the first target area, and the first water delivery pipe 71 and the first water collection pipe 81 are directly connected to each other to serve as a circulation water pipe for circulating water between the first water collection tray 51 and the first wet curtain 31.

Referring to fig. 3A, the first air conditioner 100A further includes an air duct 21-1 in air 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 air communication with the air inlet a-1 of the first target area a, and the cooling air enters the first target area a from the air inlet a-1 of the first target area a and exits the first target area a from the air outlet a-2 of the first target area a, during which the cooling air exchanges heat with the first target area a to cool the first target area a. The above cooling manner is to directly cool the first target area a with a cooling medium such as cooling air, which is called open cooling. The investment of the open cooling mode is small; especially, the air duct which can directly lead the cooling air into the peripheral structure of the building under the condition that the peripheral structure of the building is provided with the air duct (for example, the space between the external marble of the building and the outer wall), has better economical efficiency. For example, in fig. 3A, the first target area a may be an upper portion of an indoor space, an upper portion of a building interior space, a building peripheral structure itself having a duct, and the like.

For example, referring to fig. 3B, the first air conditioning equipment 100A further includes a plurality of relay fans 21-2, and the plurality of relay fans 21-2 are sequentially arranged in a direction 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 directionally 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, 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 the relay fans 21-2 may be set as appropriate according to actual conditions. For example, in fig. 3B, the first target area a may be an upper portion of an indoor space, an upper portion of a building interior space, a building peripheral structure itself having a duct, and the like.

For example, referring to fig. 3C, the first air conditioning apparatus 100A further includes a plurality of diffusers 21-3, the plurality of diffusers 21-3 delivering a portion of the cooling air into the second target area B during the movement of the cooling air from the inlet opening a-1 of the first target area a to the outlet opening a-2 of the first target area a. 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, and in this case, by providing the diffuser 21-3, a part of the cooling air introduced into the first target area a can be sent into the second target area B, thereby reducing the cooling load of the second air conditioner 100B and providing the cooling energy efficiency of the entire air conditioning system. For example, in fig. 3C, the first target area a may be an upper portion of an indoor space, an upper portion of a building inner space, or the like.

For example, referring to fig. 3D, the first air conditioning equipment 100A further includes a heat exchange air duct 21-4, the heat exchange air duct 21-4 is disposed in the first target area a, one end of the heat exchange air duct 21-4 is in air communication with an air inlet a-1 of the first target area, and the other end is in air communication with an air outlet a-2 of the first target area a. One end of the heat exchange air duct 21-4 is in gas communication with the air inlet A-1 of the first target area, so that the heat exchange branch duct 21-4 is in gas communication with the air duct 21-1, the cooling air is introduced into the heat exchange air duct 21-4 through the air duct 21-1 and exchanges heat with the first target area A in the process of flowing in the heat exchange air duct 21-4 to realize refrigeration of the first target area A. For example, the heat exchange air duct 21-4 is a corrugated duct to increase the heat exchange area between the cooling air and the first target area a. The cooling mode is that a cooling medium such as cooling air indirectly cools the first target area A through a heat exchanger such as a heat exchange air duct 21-4, and is called closed cooling. And in the closed cooling process, only heat exchange is performed, and air exchange is not performed, so that the closed cooling system is suitable for application environments with high requirements on air quality. For example, in fig. 3C, the first target area a may be an upper portion of an indoor space, an upper portion of a building interior space, an upstream area of heat flow (e.g., an upstream area of heat flow in a heat pit below a machine room floor), and so forth.

For example, referring to fig. 3E, the first air conditioner 100A includes an air duct 21-1, one end of the air duct 21-1 is in gas communication with the air outlet 21, the other end of the air duct 21-1 has an injection port 21-5, and the injection port 21-5 injects cooling air to the first target area a to cool the first target area a. In fig. 3E, the first target area a is also directly cooled, and therefore also open-cooled, by a cooling medium, such as cooling air. For example, in fig. 3E, the first target area a may be a roof of a building, a peripheral structure of an automobile, or the like.

It should be noted that, in fig. 3A-3E, only one air duct 21-1 is shown as an example; however, the disclosed embodiment is not limited thereto, and a plurality of ducts 21-1 respectively in gas communication with the outlet 21 may be provided, and the cooling air delivered by the plurality of ducts 21-1 acts on different portions of the first target area a to simultaneously cool the first target area a.

Fig. 4A-4D are schematic diagrams of cooling a first target area with cooling water from a first cooling device. Note that, in fig. 4A to 4D, the first target area a is cooled by the cooling water of the first air conditioner 100A; in this case, the first target area a may not be cooled by the cooling air of the first air conditioner 100A, and the cooling air of the first air conditioner 100A may be output to the natural environment through the outlet port 21.

For example, referring to fig. 4A, the first air conditioner 100A includes: a cooling water distributor 71-A connected to the first water delivery pipe 71, for spraying cooling water to the first target area A to refrigerate the first target area A; the water collector 81-a connected to the first water collecting pipe 81 collects and inputs water of the first target area a to the first water collecting pipe 81. The cooling water sprayed to the first target area a exchanges heat with the first target area a, so that the temperature of the first target area a is lowered and the temperature of the cooling water is raised; the water collector 81-a collects the water with increased temperature, and the water with increased temperature is conveyed to the first wet curtain 31 by the first water collecting pipe 81 to be cooled and then recycled. For example, water sprayed to the first target area A flows into the sump 81-A under the influence of gravity. For example, a plurality of first water delivery pipes 71 and a plurality of cooling water distributors 71-a connected to the plurality of first water delivery pipes 71, respectively, may be provided to spray cooling water to a plurality of portions of the first target area a at the same time, so as to improve the cooling effect. For example, a plurality of first water collecting pipes 81 and a plurality of water collectors 81-a connected to the plurality of first water collecting pipes 81 may be provided to facilitate recycling of the circulating water and save water resources. In fig. 4A, the cooling water directly cools the first target area a, which belongs to open cooling. For example, in fig. 4A, the first target area a may be a building rooftop, a building enclosure structure, a car enclosure structure, or the like.

For example, with further reference to FIG. 4A, the first air conditioner 100A further includes a water pump connected between the sump 81-A and the first water collecting pipe 81 to transfer the water collected by the sump 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 flexibility of the design of the water collector 81-a and the first water collecting pipe 81 and reducing the difficulty of installation of the apparatus.

In FIG. 4A, the water collector 81-A is near the lower portion of the first target area A; however, in FIG. 4B, the water collector 81-A is near the upper portion of the first target area A. For example, referring to fig. 4B, the sump 81-a includes: a water collection tank 81-A-1; a T-shaped downcomer 81-A-2 comprising first and second ends opposite one another and a third end remote from the first and second ends, the third end being in fluid communication with the bottom of the sump 81-A-1, the first end being in fluid communication with the first header 81; a limiting pipe 81-A-3, one end of the limiting pipe 81-A-3 is in liquid communication with the second end of the T-shaped sewer pipe 81-A-2, the other end of the limiting pipe 81-A-3 is in liquid communication with the rainwater pipe of the building, and the other end of the limiting pipe 81-A-3 in liquid communication with 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 in liquid communication with the second end of the T-shaped sewer pipe 81-A-2; and an anti-siphon port 81-A-4 opened at the other end of the stopper tube 81-A-3. For example, the water collection tank 81-A-1 may be the original water collection tank of the building, so that the water collection tank 81-A is not required to be specially provided, thereby reducing the equipment cost. Under the action of the limiting pipe 81-A-3, cooling water preferentially enters the first water collecting pipe 81 to be circularly cooled; when raining (at this time, the first air conditioner 100A may or may not operate; however, the temperature of the peripheral structure of the building is not too high during raining, and therefore, it is preferable that the first air conditioner 100A does not operate during raining), since the amount of external water is continuously increased, the water level of the down pipe 81-A-2 is continuously increased, and when the water level exceeds the upper limit water level of the limit pipe 81-A-3, the water flows to the rain pipe of the building and is finally discharged to the municipal rainwater main. For example, the anti-siphon port 81-A-4 may prevent a building storm hose from siphoning off the volume of water inside the first air conditioner 100A. For example, in fig. 4B, the first target area a may be a building roof, a building perimeter structure.

For example, referring to fig. 4C, the first air conditioner 100A further includes a heat exchanger 101, the heat exchanger 101 is disposed at the first target area a, and one end of the heat exchanger 101 is in fluid communication with the first water duct 71 and the other end is in fluid communication with the first water collecting pipe 81. The cooling water is transferred to the heat exchanger 101 disposed in the first target area a by the first water transfer pipe 71 to exchange heat with the first target area a; during the heat exchange, the temperature of the first target area a is decreased and the temperature of the cooling water is increased, and the water with the increased temperature returns to the first wet curtain 31 through the first water collecting pipe 81 to be cooled and then is recycled. In fig. 4C, the cooling water indirectly refrigerates the first target area a through the heat exchanger 101, belonging to closed cooling; it can be seen that the safety of closed cooling is high and that the cooling water does not adversely affect the electrical devices of the first target area a. For example, the heat exchanger 101 is a surface cooler. For example, in fig. 4C, the first target area a may be an upper portion of an indoor space, an upper portion of a building interior space, an upstream area of heat flow (e.g., an upstream area of heat flow in a hot pit below a machine room floor), and so forth.

For example, the first target area a includes a plurality of divisional areas spaced apart from each other, and the first air conditioner 100A includes a plurality of heat exchangers respectively located in the plurality of divisional areas of the first target area a. For example, referring to fig. 4D, taking a first target area a as an example of a peripheral structure of an automobile, the first target area a includes a plurality of sub-areas a-1 and a-2 spaced apart from each other, for example, a roof of the automobile is the sub-area a-1, a hood of the automobile is the sub-area a-2, a heat exchanger 101-1 is disposed in the sub-area a-1, and a heat exchanger 101-2 is disposed in the sub-area a-2; in this way, the vehicle roof and the vehicle hood can be cooled simultaneously, although they are remote from each other. It can be seen that the first air conditioner 100A provided by the embodiment of the present disclosure can be flexibly designed according to the specific situation of the first target area a, and has a wide application range.

It should be noted that in the above fig. 3A-3E, the first target area a is cooled by cooling air, and in the above fig. 4A-4D, the first target area a is cooled by cooling water; however, the disclosed embodiments are not limited thereto, and both cooling air and cooling water may be used to cool the first target area a, and for example, the above fig. 3A to 3E and their corresponding descriptions may be combined with the above fig. 4A to 4D and their corresponding descriptions.

In the above fig. 3A-3E the cooling air is introduced into the first target area a to refrigerate the first target area a, and in the above fig. 4A-4D the cooling water is introduced into the first target area a to refrigerate the first target area; however, the disclosed embodiments are not limited thereto, and cooling air and cooling water may be introduced into the first target zone to cool the first target zone. Fig. 5 is another structural schematic diagram of the first air conditioning device of the air conditioning system according to the embodiment of the present disclosure. For example, referring to fig. 5, the first air conditioner 100 includes: an air inlet 11, an air outlet 21, a first wet curtain 31 and a first fan 41, wherein the first wet curtain 31 is used as the cooling component, and air reaches the first wet curtain 31 from the air inlet 11 under the action of the first fan 41, becomes cooling air after passing through the first wet curtain 31 and reaches the air outlet 21; the first water collecting tray 51 is positioned below the first wet curtain 31, water in the first water collecting tray 51 reaches the first water circulating distributor 91 through the first water circulating pipe 102 under the action of the first water pump 61 and is sprayed on the first wet curtain 31 by the first water circulating distributor 91, and the water passes through the first wet curtain 31 to become cooling water and flows back to the first water collecting tray 51; the first circulating water pipe 102 is positioned on a first side of the isolating heat exchanger 103 and exchanges heat with the isolating heat exchanger 103; and the circulating heat exchanger 104 is positioned on a second side, different from the first side, of the isolating heat exchanger 103, for example, the second side is opposite to the first side, the circulating heat exchanger is filled with a cooling medium, the cooling medium exchanges heat with the isolating heat exchanger 103, and at least part of the circulating heat exchanger is positioned in the first target area A to refrigerate the first target area. The isolating heat exchanger 103 may mediate the heat exchange between the first circulating water pipe 102 at the first side thereof and the circulating heat exchanger 104 at the second side thereof, but isolate the two to prevent the exchange of substances therebetween. The cooling water reaches the isolating heat exchanger 103 through the first circulating water pipe 102, the cold energy is transmitted to the isolating heat exchanger 103, the isolating heat exchanger 103 transmits the cold energy to the cooling medium in the circulating heat exchanger 104 again, the cooling medium in the circulating heat exchanger 104 absorbs the heat of the first target area A to refrigerate the first target area A, the cooling medium in the circulating heat exchanger 104 transmits the heat to the isolating heat exchanger 103, the isolating heat exchanger 103 transmits the heat to the cooling water in the first circulating water pipe 102 again, and the cooling water which obtains the heat is cooled again through the first wet curtain 31 to circulate. For example, the cooling medium in the circulation heat exchanger 104 is not cooling water or cooling air; but a suitable cooling medium is selected according to the specific circumstances of the first target area a. For example, as shown in FIG. 5, the recycle heat exchanger 104 comprises a recycle pump. For example, the entire recycle heat exchanger 104 is located in a first target zone; in this case, the entire circulation heat exchanger 104 is transparent, for example. With the structure of fig. 5, a suitable cooling medium can be selected according to the specific situation of the first target area a, so that the first air conditioning equipment 100A provided by the embodiment of the present disclosure is more flexible in design and wider in application range. For example, in the case where the front windshield of the automobile (see, for example, fig. 4D) also needs to be cooled, the first air conditioning apparatus shown in fig. 5 may be employed, the front windshield of the automobile being the sub-area a-3 of the first target area a, at least part of the circulation heat exchanger 104 being provided between two sheets of glass of the front windshield of the automobile, on the inward side of the front windshield of the automobile, or on the outward side of the front windshield of the automobile, the front windshield of the automobile being cooled by the cooling medium; in this case, for example, the at least part of the circulation heat exchanger 104 located at the first target area a is transparent, and the cooling medium is also transparent. For example, the cooling medium may have antifreeze property, algae growth prevention property, and the like according to actual needs.

It should be noted that, with the configuration shown in fig. 5, a suitable cooling medium may be selected according to the characteristics of the first target area a; and the structure shown in fig. 5 is applicable not only to cooling of the front windshield of an automobile as described above, but also to cooling of a transparent roof, cooling of a transparent building enclosure, and the like.

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 integral structure or a separate structure.

In the above description, only one first air conditioner 100A is shown for the first target area a; however, the present embodiment is not limited thereto, and a plurality of first air conditioners 100A may be provided for the first target area a according to actual needs.

Fig. 6 is another structural schematic diagram of the first air conditioning device of the air conditioning system according to the embodiment of the present disclosure. For example, referring to fig. 6, a first air conditioning apparatus provided by an embodiment of the present disclosure further includes a first air filter; the first air filter includes: the second wet curtain 32, the air reaches the second wet curtain 32 from the air inlet 11 under the action of the first fan 41, and reaches the first wet curtain 31 after passing through the second wet curtain 32; the second water collecting tray 52 is positioned below the second wet curtain 32, the second water pump 62, the second water circulating pipe 72 and the second water circulating distributor 92, water in the second water collecting tray 52 reaches the second water circulating distributor 92 through the second water circulating pipe 72 under the action of the second water pump 62 and is sprayed on the second wet curtain 32 by the second water circulating distributor 92, and flows back to the second water collecting tray 52 after passing through the second wet curtain 32. The first air filter is located on the air intake side of the first wet curtain 31 to purify the air entering the first wet curtain 31 and reduce particulate matters in the air entering the first wet curtain 31. On the one hand, in the case of subsequent open cooling with cooling air, pure air can be supplied to the interior space. On the other hand, since the air and the circulating water meet at the first wet curtain 31, in the case where the air is purified before entering the first wet curtain 31, it is possible to reduce the evaporation of the circulating water and prevent the fouling of the structure such as the heat exchanger caused by the particulate matter or the hardness component in the cooling water when the cooling water is used for cooling. The first air filter according to the embodiment of the disclosure has a simple structure, is easy to clean, and has a very good removal effect on oily particles in air.

For example, according to the embodiment of the present disclosure, the second air conditioning apparatus 100B is at least one of a compression type air conditioner, an absorption type air conditioner, a semiconductor air conditioner, and a magnetic refrigeration air conditioner. Generally, the design temperature of the compression type air conditioner is 26 ℃ ± 2 ℃, so that the refrigeration load of the compression type air conditioner is not high when the compression type air conditioner is used to refrigerate only the low-heat second target zone B, reducing the energy consumption. Further, referring to fig. 1A-1F, the low-heat second target area B is basically an indoor personnel activity area, and a comfortable indoor environment can be provided for indoor personnel by using a compression type air conditioner.

For example, the first initial temperature of the first target area is higher than the design temperature of the second air conditioner 100B by 5 ℃ or more, in which case the first air conditioner 100A can cool the first target area a more efficiently, improving the cooling effect of the entire air conditioning system. Typically, the design temperature of a compression type air conditioner is 26 ℃ ± 2 ℃, and the first initial temperature of the first target area a is 31 ℃ or higher.

Fig. 7 is a schematic structural diagram of a second air conditioning device of the air conditioning system according to an embodiment of the present disclosure. For example, referring to fig. 7, the second air conditioner 100B includes an air inlet 23B, and the second air conditioner 100B provided by the embodiment of the present disclosure further includes a second air filter. The second air filter includes: the second air outlet 23 is in air communication with the air inlet 23B of the second air conditioning equipment 100B, air reaches the third wet curtain 33 from the second air inlet 13 under the action of the second fan 43, passes through the third wet curtain 33 and then enters the air inlet 23B of the second air conditioning equipment 100B through the second air outlet 23; the third water collecting tray 53 is positioned below the third wet curtain 33, water in the third water collecting tray 33 reaches the third water circulating distributor 93 through the third water circulating pipe 73 under the action of the third water pump 63 and is sprayed on the third wet curtain 33 by the third water circulating distributor 93, and the water flows back to the third water collecting tray 53 after passing through the third wet curtain 33. Further, for example, a second air filter is provided on the intake side of the terminal heat exchanger of the second air conditioner 100B. The traditional compression type air conditioner usually adopts a dry air filter, needs frequent cleaning and is difficult to manage, the air conditioning effect is easy to deteriorate, the energy of a fan is wasted, and particularly when the inlet air contains oil. The air filter provided by the embodiment of the disclosure is not easy to block, is easy to realize automatic cleaning, and has a good removing effect on oily particles in inlet air.

For example, according to an embodiment of the present disclosure, the first air conditioning unit 100A includes a water pump that inputs water of a natural water body into the first target area a to cool the first target area a. For example, water of natural bodies of water includes ground water and surface water. Generally, the water temperature of natural water is similar to the local annual average temperature. For example, referring to fig. 4A to 4D, the first air conditioner 100A may refrigerate the first target area a by using water of a natural water body, the water of the natural water body is input into the water pipe 71 through a water pump, and the water pipe 81 returns the water with the increased temperature after heat exchange with the first target area a to the natural water body; in this case, the water intake point of the water pump for taking water from the natural water body and the water return point of the water collection pipe 81 for returning water to the natural water body are spaced apart by a certain distance to prevent the water after heat exchange from affecting the temperature of the water input to the water delivery pipe 71, thereby affecting the refrigerating effect. For example, the first air conditioner 100A may cool the first target area using water of the natural water body, referring to fig. 5, a water pump inputs water of the natural water body into the first circulation water pipe 102, and the water in the first circulation water pipe 102 is discharged after heat exchange with the isolating heat exchanger 103 and is returned to the natural water body, for example.

For example, in summer, the first target area a is refrigerated with water from a natural body of water. For example, in winter, the first target area a is refrigerated using the cooling water as described above with reference to fig. 2.

It is understood that when the first target area a is cooled by using the water of the natural water body and the cooling water, the water delivery pipe 71 and the water collection pipe 81 may be provided for the water of the natural water body and the cooling water, respectively.

For example, the first air conditioner 100A includes a blower fan to introduce natural air into the first target area a to cool the first target area a. For example, natural air is outdoor air. The manner in which the natural air is used to cool the first target area a can be seen in fig. 3A-3E, where the natural air is delivered into the ductwork 21-1 and then into the first target area a under the influence of a blower or directly into the first target area a under the influence of a blower.

It will be appreciated that in the case where natural air and the above-described cooling air are used to simultaneously cool the first target area a, the air ducts 21-1 may be provided for the natural air and the above-described cooling air, respectively.

For example, according to an embodiment of the present disclosure, the first air conditioner 100A may also heat the first target area a having a third initial temperature, and the second air conditioner 100B may also heat the second target area B having a fourth initial temperature, the third initial temperature being lower than the fourth initial temperature, and the first air conditioner 100A employs groundwater for heating 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 peripheral structure of a building is lower than the temperature of the interior space of the building, and the temperature of the peripheral structure of an automobile is lower than the temperature of the interior space of the automobile. For example, during winter, groundwater is at a higher temperature and can be used to heat a first target area; in this case, it is possible to improve the heating efficiency of the entire air conditioning system and obtain a good heating effect. For example, the first air conditioner 100A heats the first target area a using the ground water, which is input into the water pipe 71 through a water pump, and the water collecting pipe 81 returns the water having the decreased temperature after heat exchange with the first target area a to the ground water; in this case, the water intake point of the water pump is spaced apart from the water return point of the water collection pipe 81 returning water to the ground water by a certain distance to prevent the water after heat exchange from affecting the temperature of the water input to the water delivery pipe 71, thereby affecting the heating effect. For example, the manner in which the first air conditioner 100A cools the first target area using the ground water may be as shown in fig. 5, in which a water pump inputs the ground water into the first circulation water pipe 102, and the water in the first circulation water pipe 102 is discharged after heat exchange with the isolating heat exchanger 103 and returned to, for example, a natural water body.

The third initial temperature of the first target area a is the temperature of the first target area a before heating by the first air conditioner 100A, the fourth initial temperature of the second target area B is the temperature of the second target area B before heating by the second air conditioner 100B, and the third initial temperature of the first target area a being lower than the fourth initial temperature of the second target area B is the temperature of the first target area a being lower than the temperature of the second target area B before heating by the first air conditioner 100A and the second air conditioner 100B.

For example, the third initial temperature is lower than the design temperature of the second air conditioner by 5 ℃ or more, in which case the heating effect of the first air conditioner 100A is better. Typically, the design temperature of a compression type air conditioner is 26 ℃ ± 2 ℃, and the first initial temperature of the first target area a is 21 ℃ or less.

According to an embodiment of the present disclosure, there is also provided a temperature adjustment method, including: cooling a first target zone having a first initial temperature with a first air conditioning unit; cooling a second target area having a second initial temperature using a second air conditioning unit, wherein the first target area is outside and at least partially surrounds the second target area, and the first initial temperature is higher than the second initial temperature; the first air conditioning unit uses at least one of cooling water, cooling air, water of a natural water body, and natural air for cooling the first target area.

For example, the first target area a is an upper portion of the indoor space, and the second target area B is a lower portion of the indoor space; or the first target area A is the upper part of the internal space of the building, and the second target area B is the lower part of the internal space of the building; or the first target area A is an area where a peripheral structure of the building is located, and the second target area B is an internal space of the building; or the first target area A is an area where a peripheral structure of the automobile is located, and the second target area B is an inner space of the automobile; alternatively, the first target area a is an upstream area of heat flow and the second target area B is a downstream area of heat flow. For example, as described above, the heat flow is heat flow exhausted by servers in a data center room.

It should be noted that, if the building is a single floor, the upper part of the internal space of the building is the upper part of the indoor space; if the building is multi-storey, the upper part of the building interior space is the part of the building interior space near the roof, and the upper part of the indoor space is the upper area of each storey.

For example, referring to fig. 3A, a first target area a has an air inlet a-1 and an air outlet a-2, and a temperature adjustment method according to an embodiment of the present disclosure includes: cooling air and/or natural air is caused to enter the first target area a from the air inlet a-1 of the first target area a and exit the first target area a from the air outlet a-2 of the first target area a to cool the first target area a.
