Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an air conditioning system. Background Technology

[0002] Air conditioning systems can regulate and control the temperature and humidity of a controlled area throughout the year, achieving a constant temperature and humidity. Typically, during hot and humid seasons like summer, the system needs to dehumidify at low temperatures to reduce the humidity of the supplied air. After dehumidification, the air temperature may be too low, causing the target area to become too cold, or condensation may form on the edges of the air vents due to the low supply air temperature. To address these issues, traditional air conditioning systems use external heating equipment to heat the air, raising the temperature at the air vents. This requires a significant amount of extra heat, resulting in energy waste. Utility Model Content

[0003] One of the technical problems addressed by this application is how to reduce the energy consumption of air conditioning systems.

[0004] An air conditioning system, comprising:

[0005] The conveying mechanism includes an air inlet unit and an air outlet unit;

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

[0007] The migration mechanism includes an evaporator, a condenser, a gas pipe, and a liquid pipe, wherein the gas 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] The liquid in the evaporator absorbs heat from the first channel and is converted into gas that is input to the condenser via the gas pipe. The gas in the condenser then releases heat to the second channel and is converted into liquid that is input to the evaporator via the liquid pipe.

[0009] In one embodiment, the evaporator includes a buffer tank and a plurality of dispensing components. The buffer tank has a receiving cavity. The gas pipe and the liquid pipe are both disposed on the buffer tank and their inner cavities are respectively connected to the receiving cavity. The plurality of dispensing components are spaced apart on the buffer tank. Each dispensing component includes a dispensing element and an evaporating element. The dispensing element is connected to the buffer tank, and the evaporating element is connected to the dispensing element. Liquid in the receiving cavity flows into the evaporating element through the dispensing element.

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

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

[0012] In one embodiment, the sidewall of the evaporation chamber is provided with an internal thread for liquid flow, the thread having a triangular tooth profile; or the internal thread having a single number of threads.

[0013] In one embodiment, the dispensing component includes an inner conical tube and an outer conical tube, both of which are located close to the convex tube at their larger outer diameter ends. A flow channel is formed between the inner conical tube and the outer conical tube, connecting the accommodating cavity and the receiving cavity. The orthographic projection of the end of the inner conical tube near the convex tube falls on the stepped surface.

[0014] In one embodiment, the inner conical tube includes a first conical segment and a second conical segment connected to each other, the second conical segment being closer to the convex tube than the first conical segment, the cone angle of the second conical segment being greater than the cone angle of the first conical segment, the flow channel being formed between the outer conical tube and the first conical segment, and the orthographic projection of the end of the second conical segment near the convex tube falling on the step surface.

[0015] In one embodiment, the outer conical tube includes a protrusion located within the accommodating cavity and protruding from the bottom wall of the accommodating cavity. The protrusion has a liquid inlet channel that connects the flow channel and the accommodating cavity. Along the flow direction of the liquid, the liquid inlet channel is spaced apart from the end of the protrusion.

[0016] In one embodiment, at least one of the following schemes is also included:

[0017] The liquid inlet channel 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 of the accommodating cavity than the second liquid inlet hole. The diameter of the first liquid inlet hole is smaller than or equal to the diameter of the second liquid inlet hole.

[0018] The protrusion has a through hole at one end away from the bottom wall of the accommodating cavity, and the through hole connects the accommodating cavity and the flow channel.

[0019] In one embodiment, at least one of the following schemes is also included:

[0020] The condenser includes a shell, condenser tubes, and a liquid collecting device. The shell is connected to the gas pipe. There are multiple condenser tubes, which are spaced apart on the shell. The inner cavities of the shell and the condenser tubes are interconnected. The liquid collecting device is connected to the liquid pipe and is used to guide the liquid in the condenser tubes into the liquid pipe.

[0021] The migration mechanism also includes a regulating valve, which is disposed in the liquid pipe and is horizontally arranged so that the flow direction of the liquid in the regulating valve is perpendicular to the direction of gravity.

[0022] One technical effect of one embodiment of this application is that when the air intake 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 vaporization process to form gas. Since 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 via the surface cooler and is output to the target area via the air outlet unit, if the gas temperature in the second channel is too low, the condenser will exchange heat with the gas in the second channel, causing the heat released by the condenser due to gas liquefaction to be discharged into the second channel. The gas in the second channel will absorb the heat and rise in temperature, thus effectively preventing the gas output from the air outlet unit from being too cold. The heat absorbed by the gas in the second channel comes precisely from the heat released by the gas in the first channel, allowing the air conditioning system to fully utilize the heat transferred from the first channel to the second channel without requiring an external heat source to heat the gas output from the air outlet unit, thus further reducing the energy consumption of the air conditioning system.

[0031] Furthermore, where 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 number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," 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, unless otherwise expressly limited.

[0035] See Figure 1 , Figure 2 and Figure 3An embodiment of this application provides an air conditioning system 10 including a conveying mechanism 100, a surface cooler 200, and a transfer 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. A first channel 210 exists between the surface cooler 200 and the air inlet unit 110, and a second channel 220 exists between the surface cooler 200 and the air outlet unit 120. The transfer 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 within the first channel 210, and the condenser 710 is located within the second channel 220. During operation, the air intake unit 110 introduces gas into the first channel 210, where it exchanges heat with the surface cooler 200. The surface cooler 200 absorbs the heat from the gas, cooling it before it enters the second channel 220. After cooling, the gas in the second channel 220 is 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 heat from the first channel 210 and is converted into gas that is introduced into the condenser 710 via the gas pipe 720. The gas in the condenser 710 then releases heat into the second channel 220 and is converted into liquid that is introduced into the evaporator 400 via the liquid pipe 730.

[0036] See Figure 1 , Figure 2 and Figure 3 When the air intake 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 another part of the heat is absorbed by the liquid in the evaporator 400 during the process of vaporization to form gas. Since the evaporator 400 can absorb the heat of the gas in the first channel 210, the cooling 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] See Figure 1 , Figure 2 and Figure 3When gas enters the second channel 220 from the first channel 210 via the surface cooler 200 and is output to the target area via the air outlet unit 120, if the gas temperature in the second channel 220 is too low, the temperature of the target area will also be too low, resulting in condensate at the edge of the air outlet of the air outlet unit 120. At this time, since the condenser 710 will exchange heat with the gas in the second channel 220, the heat released by the condenser 710 due to gas liquefaction will be discharged into the second channel 220. The gas in the second channel 220 will absorb the heat and rise in temperature, thus effectively preventing the gas output from the air outlet unit 120 from being too cold. The heat absorbed by the gas in the second channel 220 comes precisely from the heat released by the gas in the first channel 210, allowing the air conditioning system 10 to fully utilize the heat transferred from the first channel 210 to the second channel 220, eliminating the need for an external heat source to heat the gas output from the air outlet unit 120, thereby reducing the energy consumption of the air conditioning system 10.

[0038] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the evaporator 400 includes a buffer tank 500 and a distribution assembly 600. There are multiple distribution assemblies 600. The buffer tank 500 has a receiving cavity 510. Gas pipes 720 and liquid pipes 730 are both disposed on the buffer tank 500. The inner cavities of both gas pipes 720 and liquid pipes 730 are interconnected with the receiving cavity 510; these inner cavities are actually the cavities of both gas pipes 720 and liquid pipes 730. Multiple distribution assemblies 600 are spaced apart on the buffer tank 500. Each distribution assembly 600 includes a distribution element 610 and an evaporating element 620. The distribution element 610 is connected to the buffer tank 500, and the evaporating element 620 is connected to the distribution element 610. Liquid in the receiving cavity 510 flows into the evaporating element 620 through the distribution element 610. By setting multiple distribution components 600, multiple evaporation elements 620 are formed, which can increase the contact area between the liquid in the evaporator 400 and the gas in the first channel 210, making it easier for the liquid in each evaporation element 620 to absorb the heat in the first channel 210 and vaporize. The gas formed by vaporization will be input to the condenser 710 through the accommodating cavity 510 and the gas pipe 720.

[0039] See Figure 1 , Figure 2 and Figure 3In some embodiments, the evaporator 620 includes a convex tube 621 and an evaporator tube 622, which are interconnected. The evaporator tube 622 can be understood as protruding relative to the convex tube 621 along the axial direction of the evaporator 620, and the convex tube 621 can be understood as protruding relative to the evaporator tube 622 along the radial direction of the evaporator 620. The convex tube 621 has a receiving cavity 6211, and the evaporator tube 622 has an evaporator cavity 6221. The receiving cavity 6211 and the evaporator cavity 6221 can be coaxially arranged, and can be understood as the respective cavities of the convex tube 621 and the evaporator tube 622. The evaporator cavity 6221 has a connecting port 6212 communicating with the receiving cavity 6211. Obviously, the connecting port 6212 is located at the end of the evaporator cavity 6221 near the receiving cavity 6211. The bottom wall of the receiving cavity 6211 forms a stepped surface 6213 at its edge. The stepped surface 6213 surrounds the connecting port 6212 and is used to receive liquid from the distributor 610. The liquid discharged from the distributor 610 first enters the stepped surface 6213, then flows from the stepped surface 6213 to the edge of the connecting port 6212. Subsequently, the liquid flows downwards from the side wall of the evaporation cavity 6221 under gravity, preventing it from falling directly onto the bottom wall of the evaporation cavity 6221. This allows the liquid to exchange heat with the gas in the first channel 210 through the entire evaporation tube 622, thereby increasing the heat exchange area between the liquid in the evaporation tube 622 and the gas in the first channel 210, and thus improving the heat exchange efficiency of the evaporator 400.

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

[0041] See Figure 1 , Figure 2 and Figure 3 In some embodiments, an internal thread 6222 is provided on the side wall of the evaporation chamber 6221. During the downward flow of the liquid, the liquid slides downward along the spiral groove formed by the internal thread 6222. This effectively prolongs the flow time and path of the liquid on the side wall of the evaporation chamber 6221, allowing the liquid to achieve 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 thread 6222 is triangular; the internal thread 6222 has a single number of threads. In other embodiments, the tooth profile of the internal thread 6222 can be trapezoidal, etc., and the internal thread 6222 can also have multiple threads.

[0042] See Figure 1 , Figure 2 and Figure 3 In some embodiments, the dispensing member 610 includes an inner conical tube 611 and an outer conical tube 612. The larger outer diameter ends of both the inner conical tube 611 and the outer conical tube 612 are located close to the convex tube 621. The outer conical tube 612 is located outside the inner conical tube 611. A flow channel 6124 is formed between the inner conical tube 611 and the outer conical tube 612. The flow channel 6124 connects the accommodating cavity 510 and the receiving cavity 6211. The orthographic projection of the end of the inner conical tube 611 near the convex tube 621 falls on the stepped surface 6213. When liquid flows from the receiving cavity 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 cone tube 611 and fall onto the stepped surface 6213. This can effectively prevent the liquid flowing out of the flow channel 6124 from falling directly onto the bottom wall of the evaporation cavity 6221 without passing through the side wall of the evaporation cavity 6221. This allows the liquid to have sufficient heat exchange with the gas in the first channel 210 in the evaporation tube 622, ultimately improving the heat exchange efficiency of the evaporator 400.

[0043] See Figure 1 , Figure 2 and Figure 3In some embodiments, the inner conical tube 611 includes a first conical segment 6111 and a second conical segment 6112, which are interconnected. The second conical segment 6112 is closer to the convex tube 621 than the first conical segment 6111, meaning it is located below the first conical segment 6111. The cone angle of the second conical segment 6112 is greater than that of the first conical segment 6111, and the cone angle of the first conical segment 6111 can be equal to that of the outer conical tube 612. A flow channel 6124 is formed between the outer conical tube 612 and the first conical segment 6111, and the orthographic projection of the end of the second conical segment 6112 near the convex tube 621 falls on the stepped surface 6213. When the liquid flows out of the flow channel 6124, the liquid will flow along the second cone section 6112 and the end of the second cone section 6112 will flow into the stepped surface 6213 of the receiving cavity 6211, thereby effectively preventing the liquid flowing out of the flow channel 6124 from falling directly to the bottom wall of the evaporation cavity 6221 without passing through the side wall of the evaporation cavity 6221.

[0044] See Figure 1 , Figure 2 and Figure 3 In some embodiments, the outer conical tube 612 includes a protrusion 6121 located within the accommodating cavity 510, such that the protrusion 6121 protrudes a certain height relative to the bottom wall of the accommodating cavity 510. A liquid inlet channel 6122 is provided on the protrusion 6121, connecting the accommodating cavity 510 and the flow channel 6124. Along the liquid flow direction, the liquid inlet channel 6122 is spaced apart from the end of the protrusion 6121, meaning the liquid inlet channel 6122 is located below the end of the protrusion 6121. This allows the liquid in the accommodating cavity 510 to enter the flow channel 6124 from the side of the protrusion 6121, which can increase the area of ​​the opening connecting the liquid inlet channel 6122 and the accommodating cavity 510 to a certain extent, thereby ensuring that the liquid in the accommodating cavity 510 quickly enters the flow channel 6124 through the liquid inlet channel 6122, ultimately improving heat exchange efficiency.

[0045] See Figure 1 , Figure 2 and Figure 3 In some embodiments, the liquid inlet channel 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 protrusion 6121. The first liquid inlet hole 6122a is closer to the bottom wall surface of the receiving cavity 510 than the second liquid inlet hole 6122b. It can be understood that the second liquid inlet hole 6122b is located above the first liquid inlet hole 6122a. The diameter of the first liquid inlet hole 6122a is smaller than or equal to the diameter of the second liquid inlet hole 6122b. This allows for precise control of the flow rate and velocity of the liquid entering the flow channel 6124.

[0046] See Figure 1 , Figure 2 and Figure 3 In some embodiments, the end of the protrusion 6121 furthest from the bottom wall of the accommodating cavity 510 has a through hole 6123, which connects the accommodating cavity 510 and the flow channel 6124. By providing the through hole 6123, as the liquid in the accommodating cavity 510 enters the flow channel 6124 through the liquid inlet channel 6122, the gas in the flow channel 6124 can be quickly discharged through the through hole 6123, reducing the flow resistance of the liquid in the flow channel 6124, thereby increasing the flow rate and velocity of the liquid in the flow channel 6124, i.e., improving the fluidity of the liquid in the flow channel 6124. Ultimately, this improves the heat exchange efficiency of the evaporator 400.

[0047] See Figure 1 and Figure 5 In some embodiments, the condenser 710 includes a housing 711, condenser tubes 712, and a liquid collector 713. The housing 711 is connected to a gas pipe 720. Multiple condenser tubes 712 are spaced apart on the housing 711. The liquid collector 713 is connected to both the condenser tubes 712 and a liquid pipe 730. The inner cavities of the housing 711 and the condenser tubes 712 are interconnected. Gas output from the evaporator 400 can flow into the housing 711 through the gas pipe 720, and then the gas inside the housing 711 flows into the condenser tubes 712. This allows the gas in the condenser tubes 712 to release heat into the second channel 220. Therefore, the gas in the second channel 220 absorbs heat and heats up, preventing the gas temperature discharged from the air outlet unit 120 to the target area from being too low. After the gas in the condenser 712 releases heat, it turns into a liquid. The liquid flows into the liquid collector 713, and then flows through the liquid pipe 730 into the evaporator 400's receiving cavity 510. 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 mixture of various substances, thus containing substances with different compositions. These substances do not undergo chemical reactions, and the evaporation temperature difference between them is small, ranging from 1°C to 3°C. Similarly, the condensation temperature difference between the different substances is also small, ranging from 1°C to 3°C. The substances also have low viscosity and high fluidity. This allows for the evaporation or condensation of different substances within different temperature ranges, meeting the heat transfer requirements from the first channel 210 to the second channel 220.

[0049] See Figure 1In some embodiments, the migration mechanism 300 may further include a regulating valve 740, which is disposed in the liquid pipe 730 and is horizontally positioned. This ensures that the flow direction of the liquid in the regulating valve 740 is perpendicular to the direction of gravity. When the heat exchange medium is composed of a mixture of multiple substances, it can prevent the liquid from stratifying in the direction of gravity due to differences in density, ensuring that all components in the liquid flow uniformly in the liquid pipe 730.

[0050] See Figure 1 In some embodiments, the air intake unit 110 includes a return air fan 111, a return air valve 112, an exhaust valve 113, a mixing valve 114, a fresh air valve 115, and a filter 116. The return air fan 111 is used to transport gas, and the return air valve 112 and the exhaust valve 113 are used to control the gas flow rate. After passing through the mixing valve 114, the gas mixes with the gas entering through the fresh air valve 115, and then the gas passes through the filter 116 into 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] See Figure 1 In some embodiments, the air outlet unit 120 may include a blower 121, a heater 122, and a thermometer / hygrometer 123. Both the thermometer / hygrometer 123 and the heater 122 are disposed within the second channel 220, allowing for monitoring of the temperature and humidity of the gas within the second channel 220. The blower 121 is used to input the gas from the second channel 220 to the target area. If the temperature of the gas in the second channel 220 still does not meet the requirements after absorbing the heat released by the condenser 710, the heater 122 can be appropriately activated to heat the gas in the second channel 220. It is understood that in most cases, it is not necessary to activate the heater 122, as the gas in the second channel 220 can fully absorb the heat transferred from the first channel 210 and rise to the required temperature.

[0052] The technical features of the above embodiments can be combined in any way.
