Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a radiant panel structure, an air conditioner, and an air conditioning system. Background Technology

[0002] Existing three-constant and five-constant systems all involve installing radiant panels on the ceiling and circulating cold / heating medium pipes on the walls and floor. The cold / heating medium is recirculated through the radiant panels and pipes, and the cold or heat energy of the medium exchanges heat directly with the indoor occupants and environment through convection and radiation (primarily radiation), achieving the purpose of cooling / heating the indoor space. This type of radiant air conditioning system, equipped with a fresh air handling system, is designed as a whole, 365 days a year, with human health and comfort as its design goal. It comprehensively solves problems related to cooling, heating, fresh air, purification, humidification, and dehumidification, and has constant temperature, constant humidity, and constant oxygen levels. It is currently the most comfortable and energy-efficient air conditioning method.

[0003] Existing three-constant and five-constant radiant panels have the following drawbacks: 1. The amount of cold / heat radiation per unit area is relatively small, requiring a large area to be laid, resulting in high construction costs; 2. The cold / heat medium circulation pipelines arranged inside the radiant panels have high pressure, which may cause damage and leakage to the pipeline system after a certain period of use; 3. Multiple sets of radiant panels need to be fully installed on the ceiling of the room, but the connection between the radiant panels is arbitrary and difficult to standardize, and the large number of joints makes it difficult to guarantee quality. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a radiant panel structure, an air conditioner and an air conditioning system, which solves the problems of low cold / heat radiation, high pipeline pressure and difficulty in ensuring quality in the existing technology.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a radiant plate structure, which is a hollow flat plate structure. The radiant plate structure is provided with a water supply and exhaust zone, a heat exchange zone, and a return water zone arranged sequentially from top to bottom. The water supply and exhaust zone is connected to the heat exchange zone through a water outlet. The heat exchange zone includes a plurality of sub-heat exchange zones arranged sequentially from top to bottom. In adjacent sub-heat exchange zones, the water outlet of the upper sub-heat exchange zone and the water inlet of the lower sub-heat exchange zone are connected, and the water outlet and water inlet of each sub-heat exchange zone are staggered.

[0006] Furthermore, the radiant plate structure includes a top plate, a bottom plate, side plates, a front plate, and a back plate for forming a hollow flat plate structure. Multiple first horizontal partitions are provided inside the radiant plate structure to divide the radiant plate structure into a water supply and exhaust zone, a heat exchange zone, and a return water zone.

[0007] Furthermore, the heat exchange zone is provided with multiple second horizontal baffles to divide the heat exchange zone into multiple sub-heat exchange zones.

[0008] Furthermore, the water supply and venting area is provided with an vent at the top and a main water inlet at the bottom.

[0009] Furthermore, the main water inlet is fitted with a water inlet pipe, and the water inlet pipe is provided with a sub-outlet hole.

[0010] Furthermore, at least one vertical baffle is provided in the sub-heat exchange zone, and at least one vertical baffle in adjacent sub-heat exchange zones is located on the same straight line to form the outlet of the upper sub-heat exchange zone and the inlet of the lower sub-heat exchange zone in adjacent sub-heat exchange zones.

[0011] Furthermore, the multiple vertical partitions divide the interior of the sub-heat exchange zone into several "S"-shaped water flow heat exchange channels.

[0012] Furthermore, the vertical partitions are respectively connected to the front panel and the back panel, and air holes are provided on the vertical partitions near the upper heat exchange zone.

[0013] Furthermore, a condensate collection area for collecting condensate is also provided at the bottom of the radiant plate structure.

[0014] Furthermore, a condensate pump is installed in the condensate collection area, which is used to transfer the condensate in the condensate collection area to the return water area.

[0015] Furthermore, an insulation layer is also provided in the condensate collection area.

[0016] Furthermore, a perforated protective plate is also provided on the outer side of the radiating plate structure.

[0017] Furthermore, a return water pipe is provided at the bottom of the return water area, and a return water hole is opened on the side of the return water pipe facing the bottom of the return water area.

[0018] In a second aspect, the present invention also discloses an air conditioner, characterized in that it comprises: a circulating heat exchange water supply device and a radiant plate structure as described in any of the first aspects, wherein the circulating heat exchange water supply device comprises a separate circulating pump and a heat exchanger, the heat exchanger being connected to the return water area of ​​the radiant plate structure through the separate circulating pump, and the heat exchanger being connected to the water supply and exhaust area of ​​the radiant plate structure.

[0019] Furthermore, a first solenoid valve is also provided between the circulating pump and the return water zone; and / or, The heat exchanger and the water supply and exhaust zone are also equipped with a second solenoid valve.

[0020] Furthermore, the circulating heat exchange water supply device also includes a drain pipe and a water purifier, the water purifier being connected between the distributed circulating pump and the radiant plate structure, and the drain pipe being connected to the drain outlet of the water purifier.

[0021] Thirdly, the present invention also discloses an air conditioning system, including a main unit, a circulating water pump, and at least one air conditioner as described in the second aspect, wherein the main unit is connected to the heat exchanger of the air conditioner through the circulating water pump, and the main unit is also connected to the heat exchanger through a water pipe.

[0022] Furthermore, the circulating water pump is a chilled water pump.

[0023] Furthermore, there are several air conditioners, each installed on a different floor.

[0024] Compared to existing technologies, the above technical solution brings the following technical effects: This invention employs a radiant panel structure with a water supply and exhaust zone, a heat exchange zone, and a return water zone arranged sequentially from top to bottom. This replaces existing circulating pipes for the circulation of cold / hot media within the structure. Liquids carrying heat / cold energy can flow from top to bottom through the heat exchange zone. The heat / cold energy is radiated through the entire panel, bidirectionally conducted between the heat exchange zone and people and surrounding objects in the room. In summer, the heat energy from people and objects is radiated and conducted to the low-temperature liquid within the radiant panel structure; in winter, the heat energy from the medium-temperature liquid within the radiant panel structure is radiated and conducted to people and surrounding objects, achieving the purpose of cooling / heating the indoor space. This invention has advantages such as standardization, modularity, easier construction, and less susceptibility to damage.

[0025] Meanwhile, the radiant panel structure of the present invention can be directly installed indoors, and the outer surface of the product does not require secondary decoration or finishing. The construction cycle is greatly shortened. The entire radiant panel structure directly faces the room to emit electromagnetic radiation. The amount of cold / heat radiation per unit area is greatly increased compared with existing radiant panels. Therefore, the area to be laid is smaller and the construction cost is lower. Moreover, its direct, efficient and fast cold / heat radiation makes it easy to achieve real-time control of room temperature, and the energy-saving performance is greatly improved.

[0026] Furthermore, the radiant plate structure of the present invention achieves minimal pressure in its internal cold / hot medium, ensuring that it will not break or leak even after long-term operation. In addition, the bottom of the radiant panel structure of the present invention is provided with a condensate channel for collecting condensate. The condensate on the surface of the radiant panel structure flows downward into the condensate channel and is discharged through the condensate channel, which prevents the condensate from flowing into the ground or walls and causing mold or other damage to the indoor environment. At the same time, it is used in conjunction with anti-water contact fins to prevent people or objects from coming into contact with the condensate on the surface of the radiant panel structure and causing pollution.

[0027] The radiant panel structure of this invention is made of aluminum alloy, which has good waterproof and aesthetic properties, and prevents the product from becoming moldy. Aluminum alloy also has strong anti-oxidation properties and is very easy to machine, thereby reducing manufacturing costs and preventing rust and waste. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0035] like Figures 1 to 4 As shown, the radiant panel structure of this embodiment includes a radiant panel structure 100, which is a hollow flat plate structure. Inside the radiant panel structure 100, from top to bottom, there are a water supply and exhaust zone 110, a heat exchange zone 120, and a return water zone 130. The water supply and exhaust zone 110 is connected to the heat exchange zone 120 through a water outlet 111. The heat exchange zone 120 includes multiple sub-heat exchange zones 121 arranged from top to bottom. The water outlet 1211 of the upper sub-heat exchange zone and the water inlet 1212 of the lower sub-heat exchange zone are connected, and the water outlet 1211 and water inlet 1212 of each sub-heat exchange zone 121 are staggered. The cold / hot water medium flows naturally within the radiant panel structure 100 in a partially filled state, radiating cold / heat to the indoor space through the outer surface of the radiant panel structure 100, thus achieving cooling / heating.

[0036] Specifically, in this embodiment, the radiant panel structure 100 can be used as a pressureless radiant panel air conditioner. The water supply and exhaust zone 110 is set at the uppermost end of the radiant panel structure 100 as the water inlet. An exhaust port 112 is opened at the top of the water supply and exhaust zone 110 or at the upper end of the side of the water supply and exhaust zone 110. This exhaust port is used to remove air from the return water zone 130, the heat exchange zone 120, and the water supply and exhaust zone 110 during the water intake process, so as to eliminate the pressure of air on the liquid surface inside the radiant panel structure 100 (the water medium squeezes out the air inside the radiant panel structure 100 when it flows into the radiant panel structure 100, thereby avoiding the pressure caused by compressing the air inside the radiant panel structure 100). A main water inlet 113 is provided at the bottom of the lower side of the water supply and exhaust zone 110. In this embodiment, an inlet pipe 1121 is sleeved inside the main water inlet 113, which is connected to the external circulating water supply system. The portion of the inlet pipe 1121 located inside the water supply and exhaust zone 110 has a sub-outlet hole 11211 to evenly flow the cold / hot water medium into the water supply and exhaust zone 110. In specific implementations, it can also be connected to the external water supply system through the main water inlet 113. The number of main water inlets 113 and inlet pipes 1121 can be one or more. The number of cold / hot water medium in the circulating water supply system enters the water supply and exhaust zone 110 from the main water inlet 113 / inlet pipe 1121. An outlet hole 111 is also provided on the bottom surface of the water supply and exhaust zone 110. The cold / hot water medium in the water supply and exhaust zone 110 flows into the heat exchange zone 120 through the outlet hole 111 in the form of gravity flow. In this embodiment, the water outlet 111 is located in the middle of the bottom surface. In a specific implementation, the water outlet 111 can also be set in other locations.

[0037] To reduce the internal pressure of the radiant panel structure 100, the heat exchange zone 120 includes multiple sub-heat exchange zones 121, which are arranged sequentially from top to bottom to form multiple parallel sub-heat exchange zones 121. Each sub-heat exchange zone 121 only needs to withstand the pressure caused by the cold / hot water medium within its own layer, so that the radiant panel structure 100 can be vertically stacked and combined with multiple layers of sub-heat exchange zones 121, while the static pressure of the cold / hot water medium within each layer of sub-heat exchange zone 121 remains unchanged, and each vertically installed layer of sub-heat exchange zone 121 uniformly radiates electromagnetic radiation. The outlet 1211 of each sub-heat exchange zone 121 is located at the top, and the inlet 1212 is located at the bottom, so that the outlet 1211 and the inlet 1212 are staggered at different heights. This ensures that each sub-heat exchange zone 121 can retain a sufficient amount of cold / hot water medium, and the water medium flows in each channel in an "S" shape to prolong the time, or flows in a parallel manner to ensure that the panel temperature is basically the same. Compared with existing radiant panels, this can greatly increase the amount of cold / hot radiation per unit area.

[0038] This product utilizes a heat exchange zone 120 within the radiant panel structure 100, replacing existing circulation pipes for the internal circulation of cold / hot media. Existing radiant panels have circulation pipes occupying only a small portion (approximately 10%) of the total radiant panel area, while this product fills the entire internal space of the radiant panel with water, separated from the indoor space only by an aluminum panel, significantly improving its radiant energy efficiency. In winter, heat energy is directly radiated through the radiant panel structure 100 to people and surrounding objects. In summer, people and surrounding objects radiate heat energy through the radiant panel structure 100 to the internal refrigerant, achieving the purpose of cooling / heating the indoor space. This product can be used as a partition / wall within a room, offering advantages such as standardization, modularity, easier construction, and resistance to damage. The outer surface of the product requires no secondary decoration or finishing, or can be decorated externally by hanging / posting, significantly shortening the construction period. The radiant panel structure 1 directly faces the interior, providing direct, efficient, and rapid electromagnetic radiation, facilitating real-time temperature control and greatly improving energy-saving performance.

[0039] In one embodiment, the radiant plate structure 100 is made of aluminum alloy, which has good waterproof / thermal conductivity. In specific implementations, other materials with good waterproof / thermal conductivity can be used, and no limitation is made here.

[0040] In one embodiment, the radiant plate structure 100 includes a top plate 101, a bottom plate 102, side plates 103, a front plate 104, and a back plate 105. The radiant plate structure 100 also includes multiple first horizontal partitions 106, each connected to the front plate 104 and the back plate 105, dividing the radiant plate structure into a water supply and exhaust zone 110, a heat exchange zone 120, and a return water zone 130. In specific implementations, the radiant plate structure 100 can also be integrally formed or partially integrally formed, and then combined with other parts to form a hollow structure. For example, the side plates 103, front plates 104, back plates 105, and vertical partitions 1213 of the sub-heat exchange zone 121 can be integrally extruded and then welded together with the top plate 101 and the bottom plate 102 to form a hollow structure. In another embodiment, the front plate 104 and back plate 105 of the water supply and exhaust zone 110, heat exchange zone 120, and return water zone 130 can also not be a single piece, but can be made from independent sheet materials. In another embodiment, the heat exchange zone 120 and the return water zone 130 can also be integrally formed, while the water supply and exhaust zone 110 is a separate module. It should be noted that when the outlet of the last sub-heat exchange zone 121 is located at the upper end, the first horizontal partition 106 may not be necessary between the last sub-heat exchange zone 121 and the return water zone 130. Figure 3 , 4 As shown in Figure 5.

[0041] In one embodiment, the heat exchange zone 120 is provided with multiple second horizontal baffles 107 to divide the heat exchange zone 120 into multiple sub-heat exchange zones 121. The multiple sub-heat exchange zones 121 are stacked sequentially from top to bottom, which can divide the liquid in the radiant plate structure 100 into multiple independent areas, thereby vertically distributing the pressure in the entire radiant plate structure 100. Each sub-heat exchange zone 121 is provided with an inlet 1212 and an outlet 1211. The outlet 1211 of the upper sub-heat exchange zone is connected to the inlet 1212 of the lower sub-heat exchange zone. In order to store a sufficient amount of cold / hot water medium in each sub-heat exchange zone 121, the inlet 1212 of the upper sub-heat exchange zone in adjacent sub-heat exchange zones is located at the bottom of the sub-heat exchange zone, and the outlet 1211 of the lower sub-heat exchange zone in adjacent sub-heat exchange zones is close to the top of the sub-heat exchange zone. In one embodiment, at least one vertical baffle 1213 is provided within the sub-heat exchange zone 121. At least one vertical baffle in each adjacent sub-heat exchange zone 121 is located on the same straight line, thus connecting the outlet 1211 of the upper sub-heat exchange zone and the inlet 1212 of the lower sub-heat exchange zone. In this case, the vertical baffles on the same straight line in adjacent sub-heat exchange zones 121 are located on both sides, also serving to connect and support the internal structure. In other embodiments, the outlet 1211 of the upper sub-heat exchange zone and the inlet 1212 of the lower sub-heat exchange zone can be connected by a connecting pipe.

[0042] In one embodiment, multiple vertical baffles 1213 are provided in the sub-heat exchange zone 121. The multiple vertical baffles 1213 divide the interior of the sub-heat exchange zone 121 into several "S"-shaped water flow heat exchange channels 1214. Each water flow heat exchange channel 1214 is adjacent to each other, that is, the multiple vertical baffles 1213 are arranged at different heights. Some are connected to the bottom plate of the sub-heat exchange zone 121, and some are connected to the top plate of the sub-heat exchange zone 121. In this way, the vertical baffles 1213 can uniformly support the sub-heat exchange zone 121 while guiding the water flow in an "S"-shaped path, thereby extending the residence time of the water medium in the sub-heat exchange zone 121 during the water medium flow process, that is, allowing for longer radiative heat exchange with indoor people or objects. In this application, each vertical partition 1213 is also connected to the front panel 104 and the back panel 105. The vertical partition 1213 near the upper sub-heat exchange zone is provided with vents 12111 to ensure internal air circulation, which is ultimately discharged through the water supply and exhaust zone 110, thereby eliminating pressure within the sub-heat exchange zone 121. In other embodiments, a portion of the vertical partitions 1213 are connected to the front panel 104 (or back panel 105) and the top plate of the sub-heat exchange zone 121, while another portion of the vertical partitions 1213 are connected to the front panel 104 (or back panel 105) and the bottom plate of the sub-heat exchange zone 121. It should be noted that the top of the vertical partition 1213 connecting the front panel 104, back panel 105, and the top plate of the sub-heat exchange zone 121 (i.e., near the upper sub-heat exchange zone) is also provided with vents 12111 to ensure internal air circulation and thus eliminate pressure within the sub-heat exchange zone 121.

[0043] In one embodiment, see Figure 2 The bottom of the radiant panel structure is also equipped with a condensate collection area 140 for collecting condensate.

[0044] Specifically, the bottom of the radiant panel structure 100 is provided with a condensate collection area 140 for collecting condensate. Condensate on the surface of the radiant panel structure 100 flows downward into the condensate collection area 140, where it is collected to prevent condensate from flowing onto the ground or walls and causing mold or other indoor hygiene problems. In addition, the surface of the radiant panel structure 100 can also be used in conjunction with waterproof fins / perforated protective plates 150 installed on the outside of the radiant panel structure 100 [generally, the waterproof fins / perforated protective plates 150 are installed on the back and / or front of the radiant panel structure 100] to prevent people or objects from coming into contact with condensate on the surface of the radiant panel structure 100 and causing contamination. It should be noted that, for improved aesthetics, the outer surface of the waterproof fins / perforated protective plates 150 is basically flush with the outer surface of the condensate collection area 140.

[0045] Furthermore, a condensate pump 141 can also be installed within the condensate collection area 140. If the cold / hot water medium within the radiant panel structure 100 is water, the condensate pump 141 is used to transport the condensate in the condensate collection area 140 to the return water area 130, forming a circulation; if the cold / hot water medium within the radiant panel structure 100 is not water, the condensate in the condensate collection area 140 can be transported to the outside by the condensate pump 141. It is understood that the condensate pump 141 may not be installed within the condensate collection area 140, and the base plate of the condensate collection area 140 may be inclined to discharge the condensate to the outside through pipes.

[0046] Furthermore, an insulation layer is also provided inside the condensate collection area 140 to prevent condensate from forming on the outer surface of the condensate collection area 140 due to temperature fluctuations.

[0047] In one embodiment, a return water pipe 131 is provided at the bottom of the return water zone 130, and a return water hole 1311 is opened on the side of the return water pipe 131 facing the bottom of the return water zone 130. At this time, the liquid flowing into the return water zone 130 can flow back through the return water hole 1311.

[0048] This application also provides an air conditioner, such as Figure 6-7 As shown, the air conditioner includes a circulating heat exchange water supply unit 210 and a radiant panel structure 100 as described in any of the above embodiments. The circulating heat exchange water supply unit 210 includes a circulating pump 230 and a heat exchanger 220. The heat exchanger 220 is connected to the return water zone 130 of the radiant panel structure 100 through the circulating pump 230, and the heat exchanger 220 is also connected to the water supply and exhaust zone 110 of the radiant panel structure 100. The circulating pump 230 is used to pump the cold / hot water medium in the return water zone 130 to the heat exchanger 220. The cold / hot water medium in the heat exchanger 220 is then transported to the water supply and exhaust zone 110 through the inlet pipe 1121. The cold / hot water medium in the water supply and exhaust zone 110 then flows to the heat exchange zone 121 by gravity and continues to flow to the return water zone 130 by gravity, thereby enabling the cold / hot water medium to circulate and exchange heat between the circulating heat exchange water supply unit 210 and the radiant panel structure 100. The heat exchanger 220 can be any heat exchange device capable of energy exchange in the prior art, such as a plate heat exchanger, a shell-and-tube heat exchanger, etc. It is understood that the circulating heat exchange makeup water device 210 can be connected to multiple radiant plate structures 100.

[0049] In some embodiments, to avoid the backflow of cold / hot water medium, a first solenoid valve 240 is also provided between the circulating pump 230 and the return water zone 130. The first solenoid valve 240, in conjunction with a check valve, prevents the cold / hot water medium from flowing back into the return water zone 130 after the pump stops operating. A second solenoid valve 250 is also provided between the heat exchanger 220 and the water supply and exhaust zone 110. The second solenoid valve 250 keeps the circulating heat exchange makeup water tank 210 full of cold / hot water medium after the pump stops operating, so that it does not flow into the water supply and exhaust zone 110, which would eventually cause the cold / hot water medium in the heat exchange zone 121 to exceed the limit value.

[0050] In some embodiments, to facilitate the purification of cold / hot water medium, the circulating heat exchanger 210 further includes a drain pipe 260 and a water purifier 270, wherein the water purifier 270 is connected between the distributed circulating pump 230 and the radiant plate structure 100 (i.e., the water purifier 270 is installed on the return water pipe 131, specifically as follows). Figure 6 , 7 As shown in the diagram, one end of the drain pipe 260 is connected to the drain outlet of the water purifier 270, and the other end is connected to the outside for drainage. In a specific implementation, the circulating heat exchange water supply device 210 may also include an inlet pipe / inlet for supplying cold / hot water medium to the air conditioner.

[0051] like Figure 8 As shown, this application also discloses an air conditioning system, including: a main unit 300, a circulating water pump 400, and at least one air conditioner 200 as described in any of the above embodiments. The main unit 300 is connected to the heat exchanger 220 of the air conditioner 200 through the circulating water pump 400, and the main unit 300 is also connected to the heat exchanger 220 through a water pipe.

[0052] As one embodiment, a plurality of radiant panel structures 100 can be installed in the same indoor space. The inlet and outlet pipes of the plurality of radiant panel structures 100 are interconnected to form an air conditioner 200, and each air conditioner 200 is installed on a different floor. The air conditioner 200 described in any of the above embodiments can be installed in a building, and at least one air conditioner 200 can be installed in each room (the plurality of radiant panel structures 100 can be interconnected sequentially to form a more powerful air conditioner, or each room can have only one radiant panel structure 100, depending on the needs). The air conditioners 200 in rooms on the same floor are connected through heat exchangers 220. Specifically, the inlet of the heat exchanger 220 is connected through a horizontal inlet pipe, and the outlet of the heat exchanger 220 is connected through a horizontal outlet pipe. The horizontal inlet pipe is also connected to the vertical inlet pipe, and the horizontal outlet pipe is connected to the vertical outlet pipe, thereby connecting the heat exchangers 220 in rooms on different floors. In order to achieve centralized heating / cooling of the building, the vertical water inlet pipe and the vertical water return pipe in this application are also connected to the main unit 300. The main unit 300 can be installed on the top floor of the building, and the vertical water return pipe is connected to the main unit 300 through the circulating water pump 400.

[0053] The main unit 300 is connected to the air conditioner 200 and filled with water medium. The main unit 300 continuously heats or cools the air conditioner.

[0054] In this embodiment, the heat exchanger 220 in the air conditioning system can be a plate heat exchanger. The plate heat exchanger separates the water medium on both sides, allowing only heat exchange. The water medium on both sides of the plate heat exchanger forms a separate loop, without interference, significantly reducing the head of the circulating water pump 400. In some embodiments, the air conditioning system also includes solenoid valves installed in the horizontal inlet pipe, vertical inlet pipe, horizontal return pipe, and vertical return pipe to control the direction of water flow. Of course, regulating valves can also be installed as needed, but details are not provided here.
