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 like heating and air conditioning, gases are present in the pipes. Some of these gases are already present, some are dissolved in the water, and some are introduced by the water flow in the form of microbubbles. These gases can affect the heat exchange and normal operation of the entire system, increase noise, reduce system efficiency, and corrode and damage equipment such as pumps, boilers, and heat exchangers. In severe cases, they can form air locks, stopping the flow of water and causing the system to cease operation. Exhaust valves currently used in water systems like air conditioning and heating can remove gases from the system pipes before they are filled with the medium, but they cannot remove microbubbles or dissolved gases in the water.

[0003] Therefore, these systems require a gas-water separator that can both discharge the gas in the pipeline and the air contained in the flowing water in the pipeline to ensure the normal operation of the system. The gas-water separator referred to here is mainly used to separate gas and liquid in liquid systems. Summary of the Invention

[0004] In order to solve the above problems, the first purpose of the present invention is to provide a gas-water separation device. This solution has a simple structure, can efficiently capture the gas in the water, and can also make microbubbles more easily aggregate into large bubbles.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0006] A gas-water separation device comprises a shell, and 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; it is characterized in that: 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 spirally relative to the main shaft, and the radial wires are arranged radially relative to the main shaft.

[0007] The present invention adopts the above-mentioned technical solution, which relates to a gas-water separation device. The housing of the gas-water separation device is provided with a separation core and an exhaust assembly. The separation core is disposed in a separation chamber within the housing, and the exhaust assembly is connected to the upper end of the housing and communicates with the separation chamber. During use, the water inlet and outlet are connected to a liquid pipeline. Liquid in the pipeline flows into the separation chamber through the water inlet. Gas in the liquid adheres to the separation core, and small bubbles continuously converge into large bubbles. The bubbles rise into the upper portion of the separation core under the action of buoyancy, and the gas is eventually discharged through the exhaust assembly. The separated water flows out of the water outlet of the housing.

[0008] On this basis, the separation core in this scheme includes a main shaft, as well as spiral and radial filaments interwoven and attached to the main shaft. The main shaft serves as a supporting shaft, while the spiral and radial filaments are interlaced and connected to the main shaft. The spiral filaments are arranged helically relative to the main shaft, primarily forming dense filaments in the axial direction, while the radial filaments are arranged radially relative to the main shaft, primarily forming dense filaments in the radial direction. Based on this structure, the separation core provides dense filaments for bubble attachment in both the axial and radial directions. The simple structure can effectively capture gas in water and also allows microbubbles to more easily aggregate into large bubbles.

[0009] In a specific embodiment, the spiral filaments are arranged from sparse to dense from top to bottom.

[0010] In a specific embodiment, the radial filaments are arranged from dense to sparse from the radial inside to the radial outside.

[0011] Preferably, a water inlet connector is connected to the side wall of the shell, and the water inlet is constructed in the water inlet connector.

[0012] In a specific embodiment, the water inlet in the water inlet connector is constructed in an expanded shape with a diameter gradually increasing from the outside to the inside. In this solution, the diameter of the water inlet gradually increases, reducing the water flow pressure and making it easier for gas to precipitate.

[0013] In a further solution, a water distribution network is provided in the water inlet, and the water distribution network has a mesh structure or a porous structure.

[0014] Preferably, the exhaust assembly includes an exhaust valve and an exhaust pipe connected to the exhaust valve; the exhaust pipe is provided with a gas sensor for detecting gas. In this embodiment, the gas sensor can be used to detect gas, i.e., gas discharged from the pipe can be detected, thereby issuing a corresponding instruction, such as an alarm. More preferably, the gas sensor is configured to detect flammable and explosive gases, such as methane, so that an alarm can be issued when such flammable and explosive gases are detected.

[0015] Preferably, an annular baffle is provided inside the shell, and the separation core is provided inside the enclosed area of ​​the annular baffle and its outer edge is in contact with the inner diameter of the annular baffle; the water inlet is provided on the side wall of the shell above the annular baffle, and the water outlet is located on the side wall or bottom surface of the shell below the annular baffle. In this scheme, an annular baffle is provided to separate the interior of the shell into two upper and lower areas, and the water inlet and the water outlet are required to be located in two different areas [i.e., the upper and lower sides of the annular baffle], so as to ensure that the liquid flowing in from the water inlet must pass through the separation core inside the annular baffle before it can flow to the water outlet, thereby avoiding a short circuit between the inlet and the outlet, and ensuring that all liquids in the system pass through the separation core. Furthermore, in order to allow the gas in the liquid to be discharged smoothly, the water inlet is provided on the side wall of the shell above the annular baffle, and the water outlet is located below the annular baffle. As for the water outlet being provided on the side wall or bottom surface of the lower area, it can be adjusted as needed.

[0016] A second object of the present invention is to provide an air conditioning system using the air-water separation device as described above.

[0017] The above-mentioned air conditioning system comprises a refrigerant-side heat exchange circuit a and a water-side heat exchange circuit b. It is characterized in that the outdoor water-side heat exchange circuit b is equipped with the aforementioned gas-water separation device in the outdoor piping. In this solution, if refrigerant (primarily methane, R290) leaks from the refrigerant-side heat exchange circuit a into the water-side heat exchange circuit b, the gas-water separation device can promptly remove the refrigerant from the water-side heat exchange circuit b outdoors, preventing the refrigerant from expanding the water-side piping and entering the indoor space with the circulating water, potentially causing explosions, poisoning, and other safety hazards.

[0018] In a specific solution, 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's outdoor unit. The first heat exchange tube of the first heat exchanger, the compressor, the second heat exchanger, and the expansion valve are connected via a refrigerant pipeline. The water-side heat exchange circuit b includes an air conditioner terminal and a water pump connected to the second heat exchange tube in the first heat exchanger via a water-side pipeline. The air conditioner terminal is located indoors, and the refrigerant in the first heat exchange tube of the first heat exchanger exchanges heat with the refrigerant in the second heat exchange tube. The gas-water separation device is installed on the water-side pipeline inside or outside the air conditioner's outdoor unit. In this solution, R9 refrigerant is used in the refrigerant-side heat exchange circuit. The water-side heat exchange circuit includes an air conditioner terminal and a water pump connected to the second heat exchange tube in the first heat exchanger via a water-side pipeline. The refrigerant in the first heat exchange tube of the first heat exchanger exchanges heat with the refrigerant in the second heat exchange tube. BRIEF DESCRIPTION OF THE DRAWINGS

Example

[0027] like Figure 1 and 2 As shown, this embodiment relates to a gas-water separation device, comprising a shell 20, and a separation core 4 and an exhaust assembly 3 provided on the shell 20. A separation chamber 21, as well as a water inlet 22 and a water outlet 23 connected to the separation chamber 21, are provided 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 20 of the gas-water separation device is provided with a separation core 4 and an exhaust assembly 3, the separation core 4 is provided in the separation chamber 21 inside the shell 20, and the exhaust assembly 3 is connected to the upper end of the shell 20 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, and the liquid in the pipeline flows into the separation chamber 21 from the water inlet 22. The gas in the liquid adheres to the separation core 4, and small bubbles continuously gather 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 component 3. The separated water flows out from the water outlet 23 of the shell 20.

[0028] On this basis, the separation core 4 includes a main shaft, and spiral filaments 41 and radial filaments 42 interwoven and attached to the main shaft. The spiral filaments 41 are arranged in a spiral shape relative to the main shaft, and the radial filaments 42 are arranged radially relative to the main shaft. The main shaft serves as a supporting shaft, and the spiral filaments 41 and radial filaments 42 are staggered and connected to the main shaft. The spiral filaments 41 are arranged in a spiral shape relative to the main shaft, mainly to form dense filaments in the axial direction, and the radial filaments 42 are arranged radially relative to the main shaft, mainly to form dense filaments in the radial direction. Based on this structure, the separation core 4 provides dense filaments for bubbles to attach in the axial and radial directions. It has a simple structure, can efficiently capture gases in water, and can also make it easier for microbubbles to gather into large bubbles.

[0029] In a specific embodiment, the spiral filaments 41 are arranged from sparse to dense from top to bottom, and the radial filaments 42 are arranged from dense to sparse from radial inside to outside. Based on this scheme, a non-uniform core is constructed, which makes it easier for microbubbles to aggregate into large bubbles.

[0030] As shown in the figure, a water inlet connector 220 is connected to the side wall of the shell 20, and a water inlet 22 is constructed in the water inlet connector 220. The water inlet 22 in the water inlet connector 220 is constructed into a flared shape with a diameter gradually increasing from the outside to the inside. In this solution, the diameter of the water inlet 22 gradually increases, reducing the water flow pressure and making it easier for gas to precipitate. In a further solution, a water distribution network 24 is provided in the water inlet 22. The water distribution network 24 has a mesh structure or a porous structure. The provision of the water distribution network 24 allows the water flow to enter the separation core 4 more evenly.

[0031] As shown in the figure, an annular baffle 25 is provided inside the shell 20, and the separation core 4 is provided inside the enclosed area of ​​the annular baffle 25, with its outer edge being in contact with the inner diameter of the annular baffle 25. The water inlet 22 is provided on the shell side wall above the annular baffle 25, and the water outlet 23 is located on the shell side wall or bottom surface below the annular baffle 25. In this scheme, the annular baffle 25 is provided to separate the interior of the shell 20 into two upper and lower areas, and the water inlet 22 and the water outlet 23 are required to be located in two different areas (i.e., the upper and lower sides of the annular baffle 25), so as to ensure that the liquid flowing in from the water inlet 22 must pass through the separation core 4 inside the annular baffle 25 before flowing to the water outlet 23, thereby avoiding short circuiting of the inlet and outlet water and ensuring that all liquid in the system passes through the separation core 4. Furthermore, in order to allow the gas in the liquid to be discharged smoothly, the water inlet 22 is set on the side wall of the shell above the annular partition 25, and the water outlet 23 is below the annular partition 25. As for the water outlet 23 being set on the side wall or bottom surface of the lower area, it can be adjusted as needed.

[0032] Furthermore, the exhaust assembly 3 includes an exhaust valve 31 and an exhaust pipe 32 connected to the exhaust valve 31. The exhaust pipe 32 is provided with a gas sensor 33 for detecting gas. In this embodiment, the gas sensor 33 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, can be issued. A more preferred embodiment is that the gas sensor 33 is preferably configured to detect flammable and explosive gases, such as methane. Thus, an alarm can be issued when the corresponding flammable and explosive gas is detected. Example

[0033] A second object of the present invention is to provide an air-conditioning system, which uses the air-water separation device described in Example 1.

[0034] like Figure 3As shown, the air conditioning system includes a refrigerant-side heat exchange circuit a and a water-side heat exchange circuit b. In a specific embodiment, 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. 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 via a refrigerant pipeline 15. The water-side heat exchange circuit b includes an air conditioning terminal 52 and a water pump 53 connected to the second heat exchange pipe 112 in the first heat exchanger 11 via a water-side pipeline 51. The air conditioning terminal 52 is located indoors, and the refrigerant in the first heat exchange pipe 111 of the first heat exchanger 11 and the refrigerant in the second heat exchange pipe 112 achieve heat exchange. The gas-water separation device is arranged on the water-side pipeline 51 inside or outside the air conditioner outdoor unit 10. In this solution, R290 refrigerant is used in the refrigerant side heat exchange circuit, and the water side heat exchange circuit 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 refrigerant in the first heat exchange tube of the first heat exchanger and the refrigerant in the second heat exchange tube realize heat exchange.

[0035] The outdoor water-side heat exchange circuit b is equipped with the aforementioned gas-water separation device within its outdoor piping. In this solution, if refrigerant (primarily methane, R290) leaks from the refrigerant-side heat exchange circuit a into the water-side heat exchange circuit b, the gas-water separation device can promptly remove the refrigerant from the water-side heat exchange circuit b outdoors. This prevents R290 refrigerant from expanding the water-side piping and preventing it from circulating with the water and potentially causing explosions, poisoning, and other safety hazards.
