Description

Technical Field

[0001] The present application relates to the technical field of air conditioners, and particularly to an air conditioning system. Background Art

[0002] An air conditioning system can adjust and control the temperature and humidity of a controlled area throughout the year to achieve the purpose of constant temperature and humidity. Usually, in seasons such as summer with high temperature and high humidity, it is necessary to make the air conditioning system perform low-temperature dehumidification to reduce the supply air humidity of the air conditioning system. After low-temperature dehumidification, the air temperature may be too low, which will cause the target area to be too cold, or due to the too low supply air temperature, water droplets will condense and drip at the edge of the air supply outlet of the air conditioning system. To solve the above problems, traditional air conditioning systems use external heating devices to heat the air, so as to increase the temperature of the air at the air supply outlet. In this way, a large amount of additional heat needs to be consumed, resulting in energy waste. Summary of the Invention

[0003] One technical problem solved by the present application is how to reduce the energy consumption of an air conditioning system.

[0004] An air conditioning system includes:

[0005] A conveying mechanism, including an air inlet unit and an air outlet unit;

[0006] A surface cooler, located between the air inlet unit and the air outlet unit. There is a first channel between the surface cooler and the air inlet unit, and a second channel between the surface cooler and the air outlet unit;

[0007] A migration mechanism, including an evaporator, a condenser, an air pipe and a liquid pipe. The air pipe and the liquid pipe are connected between the evaporator and the condenser. The evaporator is located in the first channel, and the condenser is located in the second channel;

[0008] Wherein, the liquid in the evaporator absorbs the heat in the first channel to be converted into a gas input to the condenser through the air pipe, and the gas in the condenser discharges the heat to the second channel to be converted into a liquid input to the evaporator through the liquid pipe.

[0009] In one embodiment, the evaporator includes a buffer tank and a plurality of distribution components. The buffer tank has a containing cavity. The air pipe and the liquid pipe are both arranged on the buffer tank, and the inner cavities of both communicate with the containing cavity respectively. The plurality of distribution components are arranged on the buffer tank at intervals. The distribution component includes a distribution part and an evaporation part. The distribution part is connected to the buffer tank, and the evaporation part is connected to the distribution part. The liquid in the containing cavity flows into the evaporation part through the distribution part.

[0010] In one embodiment, the evaporation member includes a convex tube and an evaporation tube connected to each other. The convex tube has a receiving cavity, and the evaporation tube has an evaporation cavity. The evaporation cavity has a communication port communicating with the receiving cavity. An edge region of the bottom wall surface of the receiving cavity forms a stepped surface surrounding the communication port, and the stepped surface is used to receive liquid from the dispensing member.

[0011] In one embodiment, an annular groove is recessed on the stepped surface. The annular groove surrounds the communication port, and the annular groove is used to receive liquid from the dispensing member.

[0012] In one embodiment, internal threads for liquid flow are provided on the side wall surface of the evaporation cavity. The thread profile of the internal threads is triangular; or the internal threads are single-threaded.

[0013] In one embodiment, the dispensing member includes an inner tapered tube and an outer tapered tube. The larger-diameter ends of both the inner tapered tube and the outer tapered tube are close to the convex tube. A flow passage communicating the accommodating cavity and the receiving cavity is formed between the inner tapered tube and the outer tapered tube. The orthographic projection of the end of the inner tapered tube close to the convex tube falls on the stepped surface.

[0014] In one embodiment, the inner tapered tube includes a first tapered section and a second tapered section connected to each other. The second tapered section is closer to the convex tube than the first tapered section. The taper angle of the second tapered section is greater than that of the first tapered section. The flow passage is formed between the outer tapered tube and the first tapered section. The orthographic projection of the end of the second tapered section close to the convex tube falls on the stepped surface.

[0015] In one embodiment, the outer tapered tube includes a protruding portion protruding relative to the bottom wall surface of the accommodating cavity and located in the accommodating cavity. A liquid inlet passage communicating the flow passage and the accommodating cavity is opened on the protruding portion. Along the liquid flow direction, the liquid inlet passage is spaced from the end of the protruding portion.

[0016] In one embodiment, at least one of the following solutions is further included:

[0017] The liquid inlet passage includes a first liquid inlet hole and a second liquid inlet hole arranged at intervals. The first liquid inlet hole is closer to the bottom wall surface of the accommodating cavity than the second liquid inlet hole, and the caliber of the first liquid inlet hole is less than or equal to that of the second liquid inlet hole;

[0018] A through hole is opened at the end of the protruding portion away from the bottom wall surface of the accommodating cavity, and the through hole communicates the accommodating cavity and the flow passage.

[0019] In one embodiment, at least one of the following solutions is further included:

[0020] The condenser includes a housing, condensing tubes, and a liquid collector. The housing is connected to the air pipe. The number of the condensing tubes is multiple, and the multiple condensing tubes are arranged at intervals on the housing. The inner cavities of the housing and the condensing tubes communicate with each other. The liquid collector is connected to the liquid pipe and is used to introduce the liquid in the condensing tubes into the liquid pipe;

[0021] The transfer mechanism further includes a regulating valve. The regulating valve is arranged in the liquid pipe and is horizontally arranged so that the flowing direction of the liquid in the regulating valve is perpendicular to the direction of gravity.

[0022] One technical effect of an embodiment of the present application is that when the air inlet unit inputs gas into the first channel, part of the heat of the gas in the first channel is absorbed by the surface cooler, and another part of the heat is absorbed by the liquid in the evaporator during the process of gasification to form gas. In view of the fact that the evaporator can absorb the heat of the gas in the first channel, the cooling capacity requirement in the surface cooler can be reasonably reduced, thereby reducing the energy consumption of the surface cooler and the entire air conditioning system. When the gas enters the second channel from the first channel through the surface cooler and is output to the target area through the air outlet unit, in the case where the gas temperature in the second channel is too low, in view of the fact that the condenser will exchange heat with the gas in the second channel, the heat released due to the liquefaction of the gas by the condenser is discharged into the second channel, and the gas in the second channel will absorb heat and increase in temperature. In this way, the situation where the gas output from the air outlet unit has too low a temperature is effectively avoided. The heat absorbed by the gas in the second channel just comes from the heat released by the gas in the first channel, enabling the air conditioning system to make full use of the heat transferred from the first channel to the second channel, without the need for an external heat source to heat the gas output from the air outlet unit. In this way, the energy consumption of the air conditioning system can be further reduced. Description of the Drawings

[0031] In addition, if the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0032] In this application, unless otherwise clearly stipulated and defined, if terms such as "installed", "connected", "joined", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined.

[0035] Refer to Figure 1 、 Figure 2 and Figure 3, an air conditioning system 10 provided by an embodiment of the present application includes a conveying mechanism 100, a surface cooler 200, and a migration mechanism 300. The conveying mechanism 100 includes an air inlet unit 110 and an air outlet unit 120. The surface cooler 200 is located between the air inlet unit 110 and the air outlet unit 120. There is a first channel 210 between the surface cooler 200 and the air inlet unit 110, and there is a second channel 220 between the surface cooler 200 and the air outlet unit 120. The migration mechanism 300 includes an evaporator 400, a condenser 710, a gas pipe 720, and a liquid pipe 730. The gas pipe 720 and the liquid pipe 730 are connected between the evaporator 400 and the condenser 710. The evaporator 400 is located in the first channel 210, and the condenser 710 is located in the second channel 220. During operation, the air inlet unit 110 inputs gas into the first channel 210 and exchanges heat with the surface cooler 200, so that the cold quantity in the surface cooler 200 absorbs the heat of the gas, thereby cooling the gas to be input into the second channel 220. The gas in the second channel 220 after cooling will be output from the air outlet unit 120 to the target area, thereby controlling the temperature and humidity of the target area. The liquid in the evaporator 400 absorbs the heat in the first channel 210 to be converted into gas input into the condenser 710 through the gas pipe 720, and the gas in the condenser 710 discharges the heat to the second channel 220 to be converted into liquid input into the evaporator 400 through the liquid pipe 730.

[0036] Refer to Figure 1 , Figure 2 and Figure 3 , when the air inlet unit 110 inputs gas into the first channel 210, part of the heat of the gas in the first channel 210 is absorbed by the surface cooler 200, and the other part of the heat is absorbed by the liquid in the evaporator 400 during the process of gasification to form gas. In view of the fact that the evaporator 400 can absorb the heat of the gas in the first channel 210, the cold quantity demand in the surface cooler 200 can be reasonably reduced, thereby reducing the energy consumption of the surface cooler 200 and the entire air conditioning system 10.

[0037] Refer to Figure 1 , Figure 2 and Figure 3, when the gas enters from the first channel 210 through the surface cooler 200 into the second channel 220 and is output to the target area through the air outlet unit 120, if the gas temperature in the second channel 220 is too low, it will cause the temperature in the target area to be too low and will also cause condensate at the edge of the air outlet of the air outlet unit 120. At this time, in view of the fact that the condenser 710 will exchange heat with the gas in the second channel 220, so that the heat released by the liquefaction of the gas is discharged into the second channel 220, and the gas in the second channel 220 will absorb heat and warm up, thus effectively avoiding the situation where the gas output from the air outlet unit 120 has too low a temperature. The heat absorbed by the gas in the second channel 220 just comes from the heat released by the gas in the first channel 210, enabling the air conditioning system 10 to make full use of the heat migrated from the first channel 210 to the second channel 220, without the need for an external heat source to heat the gas output from the air outlet unit 120, so that the energy consumption of the air conditioning system 10 can be reduced.

[0038] Refer to Figure 2 , Figure 3 and Figure 4 , in some embodiments, the evaporator 400 includes a buffer tank 500 and a distribution component 600. The number of the distribution components 600 is multiple. The buffer tank 500 has a receiving cavity 510. The air pipe 720 and the liquid pipe 730 are both arranged on the buffer tank 500. The inner cavities of both the air pipe 720 and the liquid pipe 730 communicate with the receiving cavity 510. This inner cavity is actually the pipe cavities of both the air pipe 720 and the liquid pipe 730. The multiple distribution components 600 are arranged at intervals on the buffer tank 500. The distribution component 600 includes a distributor 610 and an evaporation part 620. The distributor 610 is connected to the buffer tank 500, and the evaporation part 620 is connected to the distributor 610. The liquid in the receiving cavity 510 flows into the evaporation part 620 through the distributor 610. By arranging multiple distribution components 600, multiple evaporation parts 620 are formed, so that the contact area between the liquid in the evaporator 400 and the gas in the first channel 210 can be increased, making it easier for the liquid in each evaporation part 620 to absorb the heat in the first channel 210 and vaporize. The gas formed by vaporization will be input into the condenser 710 through the receiving cavity 510 and the air pipe 720.

[0039] Refer to Figure 1 , Figure 2 and Figure 3, in some embodiments, the evaporation member 620 includes a convex tube 621 and an evaporation tube 622. The convex tube 621 and the evaporation tube 622 are connected to each other. The evaporation tube 622 can be understood as protruding relative to the convex tube 621 along the axial direction of the evaporation member 620, and the convex tube 621 can be understood as protruding relative to the evaporation tube 622 along the radial direction of the evaporation member 620. The convex tube 621 has a receiving cavity 6211, and the evaporation tube 622 has an evaporation cavity 6221. The receiving cavity 6211 and the evaporation cavity 6221 can be coaxially arranged, and the receiving cavity 6211 and the evaporation cavity 6221 can be understood as the respective tube cavities of the convex tube 621 and the evaporation tube 622. The evaporation cavity 6221 has a communication port 6212 communicating with the receiving cavity 6211. Obviously, the communication port 6212 is provided at one end of the evaporation cavity 6221 close to the receiving cavity 6211. A step surface 6213 is formed at the edge region of the bottom wall surface of the receiving cavity 6211. The step surface 6213 surrounds the communication port 6212 and is used to receive the liquid from the distribution member 610. That is, the liquid discharged from the distribution member 610 will first enter the step surface 6213, and then the liquid will flow from the step surface 6213 into the edge of the communication port 6212, and then the liquid will flow downward along the side wall surface of the evaporation cavity 6221 under the action of gravity, avoiding the liquid directly falling onto the bottom wall surface of the evaporation cavity 6221, so that the liquid generates heat exchange with the gas in the first channel 210 through the entire evaporation tube 622. In this way, the heat exchange area between the liquid in the evaporation tube 622 and the gas in the first channel 210 can be increased, thereby improving the heat exchange efficiency of the evaporator 400.

[0040] Refer to Figure 1 , Figure 2 and Figure 3 , in some embodiments, an annular groove 6214 is recessed on the step surface 6213. The annular groove 6214 surrounds the communication port 6212 and is used to receive the liquid from the distribution member 610. That is, the liquid discharged from the distribution member 610 will first enter the annular groove 6214. When the liquid level in the annular groove 6214 gradually rises and reaches the height where the communication port 6212 is located, the liquid in the annular groove 6214 will gradually overflow and flow downward along the side wall surface of the evaporation cavity 6221 from the edge of the communication port 6212, thereby increasing the heat exchange area between the liquid in the evaporation tube 622 and the gas in the first channel 210, and finally improving the heat exchange efficiency of the evaporator 400. It can be understood that when the liquid is input from the distribution member 610 into the annular groove 6214, compared with the liquid directly falling onto the step surface 6213, the splashing of the liquid can be reduced or eliminated, avoiding the splashed liquid directly falling into the bottom wall surface of the evaporation cavity 6221, and ensuring that the liquid overflowing from the annular groove 6214 will flow downward along the inner wall surface of the evaporation cavity 6221.

[0041] Refer to Figure 1 , Figure 2 andFigure 3 , in some embodiments, internal threads 6222 are provided on the side wall surface of the evaporation chamber 6221. During the downward flow of the liquid, the liquid slides downward along the spiral groove formed by the internal threads 6222. In this way, the flow time and flow path of the liquid on the side wall surface of the evaporation chamber 6221 can be reasonably extended, so that the liquid can generate sufficient heat exchange with the first channel 210 through the evaporation tube 622, thereby improving the heat exchange efficiency of the evaporator 400. For example, to further improve the heat exchange effect, the tooth profile of the internal threads 6222 is triangular; the internal threads 6222 are single-threaded. In other embodiments, the tooth profile of the internal threads 6222 can be trapezoidal, etc., and the internal threads 6222 can also be multi-threaded.

[0042] Refer to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the distributor 610 includes an inner tapered tube 611 and an outer tapered tube 612. The larger-diameter ends of both the inner tapered tube 611 and the outer tapered tube 612 are arranged close to the convex tube 621. The outer tapered tube 612 is located outside the inner tapered tube 611, and a flow channel 6124 is formed between the inner tapered tube 611 and the outer tapered tube 612. The flow channel 6124 communicates with the accommodation chamber 510 and the receiving chamber 6211. The orthographic projection of the end of the inner tapered tube 611 close to the convex tube 621 falls on the step surface 6213. When the liquid flows from the accommodation chamber 510 into the flow channel 6124, it can be ensured that the liquid in the flow channel 6124 will flow out along the end of the inner tapered tube 611 and fall onto the step surface 6213. In this way, it can effectively prevent the liquid flowing out of the flow channel 6124 from directly falling onto the bottom wall surface of the evaporation chamber 6221 without passing through the side wall surface of the evaporation chamber 6221, so that the liquid can generate sufficient heat exchange with the gas in the first channel 210 in the evaporation tube 622, and finally improve the heat exchange efficiency of the evaporator 400.

[0043] Refer to Figure 1 , Figure 2 and Figure 3, in some embodiments, the inner conical tube 611 includes a first conical section 6111 and a second conical section 6112, and the first conical section 6111 and the second conical section 6112 are in communication with each other. The second conical section 6112 is closer to the convex tube 621 than the first conical section 6111, which can be understood as the second conical section 6112 being located below the first conical section 6111. The cone angle of the second conical section 6112 is greater than the cone angle of the first conical section 6111, and the cone angle of the first conical section 6111 can be equal to the cone angle of the outer conical tube 612. A flow passage 6124 is formed between the outer conical tube 612 and the first conical section 6111. The orthographic projection of one end of the second conical section 6112 close to the convex tube 621 falls on the step surface 6213. When the liquid flows out of the flow passage 6124, the liquid will flow along the second conical section 6112 and flow the end of the second conical section 6112 onto the step surface 6213 of the receiving cavity 6211, thereby effectively preventing the liquid flowing out of the flow passage 6124 from directly dropping onto the bottom wall surface of the evaporation cavity 6221 without passing through the side wall surface of the evaporation cavity 6221.

[0044] Refer to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the outer conical tube 612 includes a protruding portion 6121, and the protruding portion 6121 is located in the accommodating cavity 510, such that the protruding portion 6121 protrudes a certain height relative to the bottom wall surface of the accommodating cavity 510. A liquid inlet passage 6122 is formed on the protruding portion 6121. The liquid inlet passage 6122 communicates the accommodating cavity 510 and the flow passage 6124. Along the flowing direction of the liquid, the liquid inlet passage 6122 is spaced apart from the end of the protruding portion 6121, which can be understood as the liquid inlet passage 6122 being located below the end of the protruding portion 6121. In this way, the liquid in the accommodating cavity 510 enters the flow passage 6124 from the side of the protruding portion 6121, which can, to a certain extent, increase the area of the opening where the liquid inlet passage 6122 communicates with the accommodating cavity 510, thereby ensuring that the liquid in the accommodating cavity 510 quickly enters the flow passage 6124 through the liquid inlet passage 6122, and ultimately improving the heat exchange efficiency.

[0045] Refer to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the liquid inlet passage 6122 includes a first liquid inlet hole 6122a and a second liquid inlet hole 6122b. The first liquid inlet hole 6122a and the second liquid inlet hole 6122b are spaced apart along the extending direction of the protruding portion 6121. The first liquid inlet hole 6122a is closer to the bottom wall surface of the accommodating cavity 510 than the second liquid inlet hole 6122b, which can be understood as the second liquid inlet hole 6122b being located above the first liquid inlet hole 6122a. The diameter of the first liquid inlet hole 6122a is less than or equal to the diameter of the second liquid inlet hole 6122b. In this way, the flow rate and speed of the liquid entering the flow passage 6124 can be precisely controlled.

[0046] Refer to Figure 1 、 Figure 2 and Figure 3 In some embodiments, a through hole 6123 is formed at one end of the protrusion 6121 away from the bottom wall surface of the accommodation cavity 510, and the through hole 6123 communicates with the accommodation cavity 510 and the flow channel 6124. By providing the through hole 6123, during the process that the liquid in the accommodation cavity 510 enters the flow channel 6124 through the liquid inlet channel 6122, the gas in the flow channel 6124 can be quickly discharged from the through hole 6123, reducing the flow resistance of the liquid in the flow channel 6124, thereby increasing the flow rate and speed of the liquid in the flow channel 6124, that is, improving the fluidity of the liquid in the flow channel 6124. Ultimately, the heat exchange efficiency of the evaporator 400 is improved.

[0047] Refer to Figure 1 and Figure 5 In some embodiments, the condenser 710 includes a housing 711, a condensing pipe 712 and a liquid collecting member 713. The housing 711 is connected to the gas pipe 720. The number of the condensing pipes 712 is multiple, and the multiple condensing pipes 712 are arranged at intervals on the housing 711. The liquid collecting member 713 is connected to both the condensing pipe 712 and the liquid pipe 730. The inner cavities of the housing 711 and the condensing pipe 712 communicate with each other. The gas output from the evaporator 400 can flow into the housing 711 through the gas pipe 720, and then the gas in the housing 711 flows into the condensing pipe 712, so that the gas in the condensing pipe 712 releases heat to the second channel 220 through the condensing pipe 712. Therefore, the gas in the second channel 220 will absorb heat and increase in temperature, avoiding the gas discharged from the air outlet unit 120 into the target area being too low in temperature. When the gas in the condensing pipe 712 releases heat, the gas will be converted into a liquid, and the liquid will flow into the liquid collecting member 713. The liquid in the liquid collecting member 713 then flows into the accommodation cavity 510 of the evaporator 400 through the liquid pipe 730. Through the conduction of the gas pipe 720 and the liquid pipe 730, the heat exchange medium in the evaporator 400 and the condenser 710 can form a closed loop, thereby continuously transferring heat from the first channel 210 to the second channel 220.

[0048] The heat exchange medium can be composed of a variety of substances mixed together. Therefore, the heat exchange medium simultaneously has substances with different components, and no chemical reactions will occur between various substances. Moreover, the evaporation temperature difference between different substances is small, and this evaporation temperature difference can be 1°C to 3°C. Of course, the condensation temperature difference between different substances is also small, and this condensation temperature difference can be 1°C to 3°C. The viscosity between various substances is small, and the fluidity is strong. Thus, within different temperature ranges, different substances can be evaporated or condensed to meet the requirements of heat transfer from the first channel 210 to the second channel 220.

[0049] Refer to Figure 1, in some embodiments, the transfer mechanism 300 may further include a regulating valve 740. The regulating valve 740 is disposed in the liquid pipe 730 and is horizontally arranged. Thus, the flow direction of the liquid in the regulating valve 740 is perpendicular to the direction of gravity. In the case where the heat exchange medium is formed by mixing multiple substances, it is possible to avoid the layering phenomenon of the liquid in the direction of gravity due to different densities, and ensure that the components in the liquid flow uniformly in the liquid pipe 730.

[0050] Refer to Figure 1 , in some embodiments, the air inlet unit 110 includes a return air fan 111, a return air valve 112, an exhaust air valve 113, a mixed air valve 114, a fresh air valve 115, and a filter 116. The return air fan 111 is used to convey gas. The return air valve 112 and the exhaust air valve 113 are used to control the flow rate of the gas. After the gas passes through the mixed air valve 114, it is mixed with the gas entering from the fresh air valve 115, and then the gas passes through the filter 116 and enters the first channel 210. The filter 116 filters impurities in the gas. The filtered gas will exchange heat with the evaporator 400 and the surface cooler 200 in the first channel 210.

[0051] Refer to Figure 1 , in some embodiments, the air outlet unit 120 may include a supply air fan 121, a heater 122, and a temperature and humidity meter 123. The temperature and humidity meter 123 and the heater 122 are both disposed in the second channel 220 and can monitor the temperature and humidity of the gas in the second channel 220. The supply air fan 121 is used to input the gas in the second channel 220 into the target area. In the case where the temperature of the gas in the second channel 220 still cannot meet the requirements after absorbing the heat released by the condenser 710, the heater 122 can be appropriately turned on to heat the gas in the second channel 220. It can be understood that in most cases, the heater 122 does not need to be turned on, and the gas in the second channel 220 can completely absorb the heat transferred in the first channel 210 and rise to the required temperature.
