Description

Technical Field

[0001] The present invention relates to the field of air conditioning systems, and in particular to an air conditioning system and an air-water separation device thereof. Background Art

[0002] In water systems such as heating or air conditioning, there are gases in the pipes. Some of these gases are originally in the pipes, some are dissolved in the water, some are brought in by the water flow in the form of microbubbles, and some are refrigerants leaking from the air conditioning system into the water system. Some of these gases are flammable. Once leaked, they will cause explosions that endanger the personal safety of users. They will also affect the heat exchange effect of the entire system and the normal operation of the system, increase noise, reduce system efficiency, and cause corrosion and damage to equipment such as water pumps, boilers, and heat exchangers. In severe cases, air plugs may form, causing the water flow to stop flowing, resulting in the system being unable to operate. The exhaust valve currently used in water systems such as air conditioning and heating can remove the gas existing in the system pipe before it is filled with the medium, but it is difficult to remove the microbubbles and gases dissolved in the water in time. Therefore, in these systems, a gas-water separator is needed that can both discharge the gas in the pipe and discharge the air contained in the flowing water in the pipe in time to ensure the normal operation of the system.

[0003] Prior art, such as the Chinese utility model patent with the announcement number "CN221254018U", involves an air conditioning system and an air-water separation device thereof. An air-water separation device comprises a shell, a separation core and an exhaust assembly arranged on the shell; a separation chamber, and a water inlet and a water outlet connected to the separation chamber are arranged inside the shell; the separation core is arranged inside the separation chamber, and the exhaust assembly is connected to the upper end of the shell and connected to the separation chamber; the separation core comprises a main shaft, and spiral wires and radial wires interwoven and attached to the main shaft; the spiral wires are arranged in a spiral shape relative to the main shaft, and the radial wires are arranged radially relative to the main shaft.

[0004] This solution has the following two problems:

[0005] First, the separation core structure adopted in this solution is relatively complex and the cost is relatively high;

[0006] Second, the solution further places the water outlet below the annular partition, specifically below the separation core, so that the liquid flowing in from the water inlet must pass through the separation core inside the annular partition before flowing to the water outlet. However, this will cause a short circuit between the water inlet and the water outlet, that is, the part of the separation core that is far from the closest path between the water inlet and the water outlet will not be able to function. Summary of the invention

[0007] In order to solve the above problems, the purpose of the present invention is to provide a gas-water separation device, which can not only increase the air attachment area on the separation core, but also guide the liquid flow direction and make full use of the attachment surface of the separation core; in this way, it is easier to collect the gas in the liquid and improve the gas capture efficiency.

[0008] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0009] An air-water separation device comprises a shell, and a separation core and an exhaust assembly arranged in the shell; a separation chamber, and a water inlet and a water outlet connected to the separation chamber are arranged inside the shell; the separation core is arranged inside the separation chamber, and the exhaust assembly is connected to the upper end of the shell and is connected to the separation chamber; it is characterized in that: the separation core comprises a plurality of core units uniformly arranged circumferentially along the center of the separation chamber; each core unit comprises at least an outer annular separation plate and an inner annular separation plate arranged concentrically, and both the outer annular separation plate and the inner annular separation plate are mesh plates.

[0010] The present invention adopts the above technical solution, which relates to a gas-water separation device, wherein a separation core and an exhaust assembly are arranged on the shell of the gas-water separation device, the separation core is arranged in a separation chamber in the shell, and the exhaust assembly is connected to the upper end of the shell and communicates with the separation chamber. When in use, the water inlet and the water outlet are connected to the liquid pipeline, the liquid in the pipeline flows into the separation chamber through the water inlet, the gas in the liquid adheres to the separation core, small bubbles continuously gather into large bubbles, and the bubbles rise into the upper part of the separation core under the action of buoyancy, and finally the gas is discharged through the exhaust assembly, and the separated water flows out from the water outlet of the shell.

[0011] On this basis, the difference between this solution and the prior art is that the separation core in this solution adopts a plurality of core units arranged regularly in the circumferential direction, and each core unit includes at least an outer annular separation plate and an inner annular separation plate arranged concentrically. Based on the above solution, after the liquid flows into the separation chamber from the water inlet, part of the liquid can flow along the periphery of the plurality of core units, so that the gas in the part of the liquid adheres to the outer side wall of the outer annular separation plate; in addition, part of the liquid can flow through the holes of the outer annular separation plate and the inner annular separation plate, so that the gas in the part of the liquid can adhere to the inner side wall of the outer annular separation plate and the inner and outer side walls of the inner annular separation plate.

[0012] In summary, the above scheme can not only increase the air attachment area on the separation core, but also guide the liquid flow direction and make full use of the attachment surface of the separation core; thus, it is easier to collect the gas in the liquid and improve the gas capture efficiency.

[0013] In some other solutions, at least one layer of middle annular separation plate may be provided between the outer annular separation plate and the inner annular separation plate, so as to further improve the gas capture efficiency.

[0014] In a specific embodiment, the outer annular separation plate and the inner annular separation plate are connected by a plurality of radially distributed connecting ribs, the inner end of the connecting rib is connected to the inner annular separation plate, and the outer end is connected to the outer annular separation plate. In this scheme, a plurality of radial connecting ribs can be used to connect the outer annular separation plate and the inner annular separation plate, so that the outer annular separation plate and the inner annular separation plate are arranged concentrically.

[0015] In a further preferred embodiment, the through-hole density on the inner annular separation plate is greater than the through-hole density on the outer annular separation plate. In this embodiment, it is difficult for large bubbles to pass through the inner annular separation plate and adhere to the outer wall of the inner annular separation plate, and the inner wall of the inner annular separation plate can be further attached to small bubbles, so that microbubbles can be gathered into large bubbles.

[0016] In a specific embodiment, the separation core also includes a main shaft fixed at the center of the separation cavity, and the inner ends of the plurality of core units are fixedly connected to the main shaft. In this scheme, the inner ends of the plurality of core units can be fixed to the main shaft, thereby facilitating the fixing and circumferential regular arrangement of the core units.

[0017] In a further solution, the outer annular separation plates of the multiple core units are adjacent or tangent, and a gap is left between the outer annular separation plates of the core units and the inner wall of the separation chamber of the shell. The solution here requires that the multiple core units are as close or close as possible, so that for the liquid passing through the separation core, it is possible to flow along the surface of the outer annular separation plate to facilitate gas replenishment. Furthermore, a gap is left between the outer annular separation plate of the core unit and the inner wall of the separation chamber of the shell, so that the liquid can flow through the gap between the separation core and the inner wall of the separation chamber, thereby making full use of the outer surface of the outer annular separation plate to capture bubbles.

[0018] In a specific solution, the water inlet and the water outlet are arranged on opposite sides of the shell. In this way, the liquid flows from the water inlet to the water outlet in multiple directions, and the surface of the core unit is fully utilized to improve the gas capture efficiency; and the problem of short circuit from the water inlet to the water outlet as described in the background technology will not occur.

[0019] Preferably, a water inlet joint is connected to the side wall of the shell, and a water inlet is constructed in the water inlet joint; the water inlet in the water inlet joint is constructed in an expanded shape with a diameter gradually increasing from the outside to the inside, and a water distribution net is arranged in the water inlet, and the water distribution net is a mesh structure or a porous structure. In this scheme, the diameter of the water inlet gradually increases, reducing the water flow pressure, and the gas is more easily precipitated.

[0020] Preferably, the exhaust assembly includes an exhaust valve and an exhaust pipe connected to the exhaust valve; a gas sensor for detecting gas is provided on the exhaust pipe. In this solution, the gas sensor can be used to detect gas, that is, the exhaust gas in the pipe can be detected, and then a corresponding instruction, such as an alarm, is issued. A more preferred solution is that the gas sensor is preferably configured to be a sensor capable of detecting flammable and explosive gases, such as methane gas; so that an alarm can be issued when the corresponding flammable and explosive gas is detected.

[0021] An air conditioning system, characterized in that: the system is provided with an air-water separation device as described in any of the above items.

[0022] An air conditioning system comprises a refrigerant side heat exchange circuit (a) and a water side heat exchange circuit (b); characterized in that: the water side heat exchange circuit (b) is provided with a gas-water separation device as described in any of the above items in the outdoor pipe process; in this scheme, when refrigerant [mainly methane, R] leaks from the refrigerant side heat exchange circuit a to the water side heat exchange circuit b, the gas-water separation device can be used to timely discharge the refrigerant in the water side heat exchange circuit b outdoors, thereby avoiding the refrigerant from expanding the water side pipeline and avoiding the refrigerant from entering the room with the water circulation and inducing safety accidents such as explosion and poisoning.

[0023] In a specific scheme, the refrigerant side heat exchange circuit (a) includes a first heat exchanger, a second heat exchanger, a compressor and an expansion valve located inside the air conditioner outdoor unit, and the first heat exchange tube of the first heat exchanger, the compressor, the second heat exchanger and the expansion valve are connected through a refrigerant pipeline; the water side heat exchange circuit (b) includes an air conditioning terminal and a water pump connected to the second heat exchange tube in the first heat exchanger through a water side pipeline, the air conditioning terminal is located indoors, and the refrigerant in the first heat exchange tube of the first heat exchanger realizes heat exchange with the refrigerant in the second heat exchange tube; the gas-water separation device is arranged on the water side pipeline inside or outside the air conditioner outdoor unit.

[0032] Embodiment 1:

[0033] like Figure 1 and 2As shown, this embodiment relates to a gas-water separation device, including a shell 20, and a separation core 4 and an exhaust assembly 3 arranged in the shell 20. A separation chamber 21, and a water inlet 22 and a water outlet 23 connected to the separation chamber 21 are arranged inside the shell 20. The separation core 4 is arranged inside the separation chamber 21, and the exhaust assembly 3 is connected to the upper end of the shell 20 and is connected to the separation chamber 21. The shell of the gas-water separation device is provided with a separation core 4 and an exhaust assembly 3, the separation core 4 is arranged in the separation chamber in the shell, and the exhaust assembly 3 is connected to the upper end of the shell and is connected to the separation chamber 21. When in use, the water inlet 22 and the water outlet 23 are connected to the liquid pipeline, the liquid in the pipeline flows into the separation chamber 21 through the water inlet 22, the gas in the liquid adheres to the separation core 4, small bubbles are continuously gathered into large bubbles, the bubbles rise into the upper part of the separation core 4 under the action of buoyancy, and finally the gas is discharged through the exhaust assembly 3, and the separated water flows out from the water outlet 23 of the shell.

[0034] like Figure 1 As shown, the exhaust assembly 3 includes an exhaust valve 31 and an exhaust pipe 32 connected to the exhaust valve 31. A gas sensor 33 for detecting gas is provided on the exhaust pipe 32. In this solution, the gas sensor can be used to detect gas, that is, the exhaust gas in the pipeline can be detected, and then a corresponding instruction, such as an alarm, is issued. A better solution is that the gas sensor is preferably configured to be a sensor capable of detecting flammable and explosive gases, such as methane gas. Thus, an alarm can be issued when the corresponding flammable and explosive gas is detected.

[0035] like Figure 2 As shown, the separation core 4 includes a main shaft 41 fixed at the center of the separation chamber 21, and a plurality of core units 42 uniformly arranged circumferentially along the center of the separation chamber 21. The inner ends of the plurality of core units 42 are fixedly connected to the main shaft 41. In the scheme here, the inner ends of the plurality of core units 42 can be fixed on the main shaft 41, so as to facilitate the fixation and circumferential regular arrangement of the core units 42. In a specific embodiment, each core unit 42 includes at least an outer annular separation plate 421 and an inner annular separation plate 422 arranged concentrically, and the outer annular separation plate 421 and the inner annular separation plate 422 are both mesh plates. In some other schemes, at least one layer of middle annular separation plate can be arranged between the outer annular separation plate 421 and the inner annular separation plate 422, and the middle annular separation plate is also a mesh plate, so as to further improve the gas replenishment efficiency.

[0036] The difference between this solution and the prior art is that the separation core 4 in this solution adopts a plurality of core units 42 regularly arranged in the circumferential direction, and each core unit 42 includes at least an outer annular separation plate 421 and an inner annular separation plate 422 arranged concentrically. Based on the above solution, after the liquid flows into the separation chamber 21 from the water inlet 22, part of the liquid can flow along the periphery of the plurality of core units 42, so that the gas in the part of the liquid adheres to the outer wall of the outer annular separation plate 421. In addition, part of the liquid can flow through the holes of the outer annular separation plate 421 and the inner annular separation plate 422, so that the gas in the part of the liquid can adhere to the inner wall of the outer annular separation plate 421 and the inner and outer walls of the inner annular separation plate 422. In summary, the above solution can not only increase the air attachment area on the separation core 4, but also guide the liquid flow direction and make full use of the attachment surface of the separation core 4. In this way, it is easier to collect the gas in the liquid and improve the gas capture efficiency.

[0037] In a further solution, the outer annular separation plates 421 of the plurality of core units 42 are adjacent or tangent to each other, and a gap 420 is left between the outer annular separation plates 421 of the core unit 42 and the inner wall of the separation chamber 21 of the shell 20. The solution here requires that the plurality of core units 42 are as close or close to each other as possible, so that the liquid passing through the separation core 4 can flow along the surface of the outer annular separation plate 421 as much as possible, which is convenient for gas replenishment. Furthermore, a gap 420 is left between the outer annular separation plate 421 of the core unit 42 and the inner wall of the separation chamber 21 of the shell 20, so that the liquid can flow through the gap 420 between the separation core 4 and the inner wall of the separation chamber 21, thereby making full use of the outer surface of the outer annular separation plate 421 to capture bubbles.

[0038] In a specific embodiment, the outer annular separation plate 421 and the inner annular separation plate 422 are connected by a plurality of radially distributed connecting ribs 423, the inner end of the connecting rib 423 is connected to the inner annular separation plate 422, and the outer end is connected to the outer annular separation plate 421. In this scheme, a plurality of radial connecting ribs 423 can be used to connect the outer annular separation plate 421 and the inner annular separation plate 422, so that the outer annular separation plate 421 and the inner annular separation plate 422 are concentrically arranged. In addition, in a preferred scheme, the through-hole density on the inner annular separation plate 422 is greater than the through-hole density on the outer annular separation plate 421. In this scheme, it is not easy for large bubbles to pass through the inner annular separation plate 422 and attach to the outer wall of the inner annular separation plate 422, and the inner wall of the inner annular separation plate 422 can be further attached to small bubbles, so that microbubbles can be easily gathered into large bubbles.

[0039] like Figure 1 and 2As shown, the water inlet 22 and the water outlet 23 are arranged on opposite sides of the shell 20. In this way, the liquid flows from the water inlet 22 to the water outlet 23 in multiple directions, and the surface of the core unit 42 is fully utilized to improve the gas capture efficiency. And the problem of short circuit from the water inlet 22 to the water outlet 23 as described in the background technology will not occur. A water inlet joint 220 is connected to the side wall of the shell 20, and the water inlet 22 is constructed in the water inlet joint 220. The water inlet 22 in the water inlet joint 220 is constructed into an expanded shape with a diameter gradually increasing from the outside to the inside, and a water distribution network 24 is provided in the water inlet 22, and the water distribution network 24 is a mesh structure or a porous structure. In this scheme, the diameter of the water inlet 22 is gradually enlarged, the water flow pressure is reduced, and the gas is more easily precipitated.

[0040] In summary, the characteristics and advantages of the new steam-water separator are as follows:

[0041] 1) The structure is simple and can efficiently capture non-condensable gases in water.

[0042] 2) The diameter of the water inlet 22 is gradually enlarged to reduce the water flow pressure, making it easier for gas to precipitate.

[0043] 3) The concentric core makes it easier for microbubbles to aggregate into large bubbles.

[0044] 4) Add a gas sensor to the exhaust port to increase the alarm function

[0045] 5) Multiple circular filter elements are evenly arranged to form a curved flow channel, allowing the water flow to change its flow direction multiple times. Bubbles are more likely to accumulate on the filter element due to inertia.

[0046] 6) When the circular filter element allows water to enter, the water flow changes from linear motion to circular motion, generating centrifugal force to separate small bubbles, making them easier to be captured by the filter element.

[0047] 7) Multiple concentric circles are designed with channels between them to separate air and water, thus reducing the interference of water flow on the gathering and rising of bubbles.

[0048] 8) Multiple round filter elements, smaller volume for the same surface area

The water side heat exchange circuit b is provided with a gas-water separation device 2 as described in any of the above items in the outdoor pipe process, and the gas-water separation device 2 is preferably provided in the water side heat exchange circuit b in the outdoor unit. In this scheme, when the refrigerant [mainly methane, R290] leaks into the water side heat exchange circuit b in the refrigerant side heat exchange circuit a, the above-mentioned gas-water separation device can be used to timely discharge the refrigerant in the water side heat exchange circuit b outdoors, which can avoid the refrigerant from expanding the water side pipeline, and avoid the refrigerant from entering the room with the water circulation and inducing safety accidents such as explosion and poisoning.

[0051] In a further solution, the refrigerant side heat exchange circuit a includes a first heat exchanger 11, a second heat exchanger 12, a compressor 13 and an expansion valve 14 located inside the air conditioner outdoor unit 10, and the first heat exchange pipe 111 of the first heat exchanger 11, the compressor 13, the second heat exchanger 12 and the expansion valve 14 are connected through a refrigerant pipeline 15.
