Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a gas-liquid separator and HVAC equipment. Background Technology

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] In the heat exchange system of HVAC equipment, there are usually two components: a refrigerant circulation system and a coolant circulation system. The refrigerant system exchanges heat with the coolant system to regulate the temperature of the coolant and also exchanges heat with the room through the coolant system.

[0004] The refrigerant system is located outdoors. When the refrigerant system leaks, the leaked refrigerant may enter the room along with the coolant, posing a safety hazard to the user. Utility Model Content

[0005] The purpose of this application is to at least solve the problem of refrigerant leakage into indoor spaces. This purpose is achieved through the following technical solution: A first aspect of this application provides a gas-liquid separator, the gas-liquid separator comprising: The housing has a flow channel and an inlet, an outlet, and an exhaust port that are respectively connected to the flow channel. The inlet has a first axis that is angled to a first direction. The flow channel has a second axis that is aligned with the first direction. Along the first direction, the outlet and the exhaust port are located at opposite ends of the housing, and the exhaust port is located above the outlet. A flow-dispersing element is disposed within the housing, with at least a portion of the flow-dispersing element located between the liquid inlet and the liquid outlet.

[0006] When the gas-liquid separator of this application is used in HVAC equipment, during the operation of the heat exchange system, the refrigerant in the first heat exchange device of the heat exchange system exchanges heat with the coolant through the second component of the second heat exchange device. After heat exchange, the coolant exchanges heat indoors through the first component of the second heat exchange device to meet the indoor temperature regulation requirements. When refrigerant leaks and flows with the coolant, as the coolant flows through the gas-liquid separator, the coolant carrying the refrigerant enters the flow channel through the inlet and flows out through the outlet. During the flow of the coolant towards the outlet, the turbulence-inducing component turbules the coolant, causing the refrigerant mixed in the coolant to separate from the coolant. The separated coolant flows downward through the outlet, and the separated refrigerant is discharged upward through the exhaust port.

[0012] In some embodiments of this application, the housing is further provided with at least one limiting structure, which is disposed in the flow channel. Along the first direction, the at least one limiting structure is spaced apart from the exhaust valve.

[0013] In some embodiments of this application, there are multiple limiting structures, and the multiple limiting structures are spaced apart along the circumferential direction of the flow channel.

[0014] In some embodiments of this application, the disturbance body includes: A plurality of first rods are radially distributed on the outer peripheral surface of the retaining body; The second rod is spirally arranged around the retaining body. The second rod is spaced apart from the retaining body and is connected to the plurality of first rods respectively. The second rod and the first rods form a cage-like structure.

[0015] In some embodiments of this application, the housing further includes at least one reserved interface having a fourth axis that is angled to the first direction.

After heat exchange, the coolant exchanges heat indoors through the first component to meet the indoor temperature regulation requirements. When refrigerant leaks and flows with the coolant, as the coolant flows through the gas-liquid separator, the coolant carrying the refrigerant enters the flow channel through the inlet and flows out through the outlet. During the flow of the coolant towards the outlet, the turbulence-inducing component turbules the coolant, causing the refrigerant mixed in the coolant to separate from the coolant.

The coolant, after heat exchange, then passes through the first component of the second heat exchange device to exchange heat within the room, thus meeting the requirements for indoor temperature regulation. When refrigerant leaks and flows with the coolant, as the coolant passes through the gas-liquid separator, the coolant carrying the refrigerant enters the flow channel through the inlet and flows out through the outlet. During the flow towards the outlet, the flow-turbulent component turbules the coolant, causing the refrigerant mixed in with the coolant to separate from the coolant. The separated coolant flows downwards through the outlet, while the separated refrigerant is discharged upwards through the exhaust port. This reduces the possibility of refrigerant entering the room, thereby lowering safety hazards for users.

[0022] In some embodiments of this application, the second component further includes a plurality of functional components, each of which is mounted on a reserved connector on the housing of the gas-liquid separator. The functional component is connected to the flow channel through a reserved interface on the reserved connector.

[0027] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0028] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0029] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0030] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0031] like Figures 1 to 12 As shown, according to an embodiment of this application, a gas-liquid separator 21 is proposed, which can be used in a heating, ventilation and air conditioning system 100.

[0032] The HVAC system 100 includes an indoor unit and an outdoor unit, which are connected by pipes to form a heat exchange system. This heat exchange system includes a first heat exchange device 1 and a second heat exchange device 2. The first heat exchange device 1 circulates refrigerant and is located outdoors. The second heat exchange device 2 circulates coolant and includes a first component 10 and a second component 20. The first component 10 is located indoors and exchanges heat with the indoor environment. The second component 20 is located outdoors and is thermally connected to the first heat exchange device 1, enabling the refrigerant to exchange heat with the coolant.

[0033] Specifically, the first heat exchange device 1 forms a first loop, through which refrigerant (e.g., R22, R32, R290, R410A, R134A, etc.) circulates. The first heat exchange device 1 includes multiple first functional components connected in series in the first loop. These components work together to circulate the refrigerant within the first loop and to change the refrigerant's state. Among the multiple first functional components are a compressor and a heat exchanger. The compressor drives the refrigerant to circulate in the first loop, and the heat exchanger facilitates heat exchange between the refrigerant and the outdoor air.

[0034] The second heat exchange device 2 forms a second loop for circulating coolant. The first component 10 and the second component 20 are connected by pipes to form the second loop, which circulates coolant (e.g., deionized water, propylene glycol, or a mixture of propylene glycol and deionized water). The second heat exchange device 2 includes multiple second functional devices, some of which are included in the first component 10 and others in the second component 20. The first component 10 specifically includes a first heat exchange element and a drive pump. The first heat exchange element has a first channel and a second channel, which are isolated from each other and capable of exchanging heat with each other. The first loop is connected in series with the first channel, forming a partial first loop, and the second channel is connected in series with the second loop, forming a partial second loop. When the refrigerant circulates to the first channel, it exchanges heat with the coolant in the second channel, thus regulating the coolant temperature using the refrigerant. The drive pump is connected in series with the second loop, driving the coolant to circulate within the second loop. The second component 20 specifically includes a second heat exchanger, which is connected in series in the second circuit. The second heat exchanger is installed indoors, and the coolant after exchanging heat with the refrigerant exchanges heat with the indoors through the second heat exchanger to meet the indoor heat exchange requirements (such as regulating the indoor temperature, or being installed in the indoor water storage tank and at least heating the water in the water storage tank to provide hot water for the indoors).

[0035] The second component 20 includes a first pipe and a second pipe. The first pipe is connected to the inlet of the second heat exchanger, and the second pipe is connected to the outlet of the second heat exchanger. The coolant, after exchanging heat with the refrigerant, flows into the second heat exchanger through the first pipe. After exchanging heat with the room through the second heat exchanger, the coolant flows out through the second pipe and enters the second channel of the first heat exchanger to exchange heat with the refrigerant again.

[0036] The second component 20 also includes an outdoor gas-liquid separator 21, which is connected in series with the first pipeline. The gas-liquid separator 21 can be installed on the first pipeline or upstream of it. Before entering the second heat exchanger located indoors, the coolant passes through the gas-liquid separator 21 to separate the coolant from the gas, thus reducing the likelihood of refrigerant entering the room with the coolant.

[0037] In some embodiments of this application, the gas-liquid separator 21 includes a flow-turbing element 28 and a housing 211. The housing 211 is provided with an inlet 213, an outlet 215, an exhaust port 217, and a flow channel 216. The inlet 213, outlet 215, and exhaust port 217 are respectively connected to the flow channel 216. The housing 211 has an approximately cylindrical structure and an axial direction. The inlet 213 has a first axis a, which forms an angle with a first direction (which can be understood as vertical when the gas-liquid separator 21 is in the installed state). The flow channel 216 has a second axis b, which is consistent with the axial direction of the housing 211. The exhaust port 217 and outlet 215 are located at opposite ends of the housing 211 along the first direction, with the exhaust port 217 positioned above the outlet 215. The flow deflector 28 is disposed within the flow channel 216, and at least a portion of the body of the flow deflector 28 is disposed between the inlet 213 and the outlet 215.

[0038] When the gas-liquid separator 21 is used in the HVAC system 100, during operation of the heat exchange system of the HVAC system 100, the refrigerant in the first heat exchange device 1 exchanges heat with the coolant through the second component 20 of the second heat exchange device 2. After heat exchange, the coolant exchanges heat in the room through the first component 10 to meet the indoor temperature regulation requirements. When refrigerant leaks and flows with the coolant, when the coolant flows through the gas-liquid separator 21, the coolant carrying the refrigerant enters the flow channel 216 through the inlet 213 and flows out through the outlet 215. During the flow of the coolant towards the outlet 215, the turbulence member 28 turbulents the coolant, causing the refrigerant mixed in the coolant to separate from the coolant. The separated coolant flows downward through the outlet 215, and the separated refrigerant is discharged upward through the exhaust port 217. In this way, the possibility of refrigerant entering the room can be reduced, thereby reducing the safety hazards during user operation.

[0039] In addition, the first axis a of the inlet 213 is set at an angle to the first direction, and the outlet 215 is set at one end of the second axis b of the flow channel 216. This makes the flow direction of the coolant in the flow channel 216 bend, which can extend the flow path of the coolant in the gas-liquid separator 21, increase the chance of the coolant coming into contact with the turbulence member 28, and further improve the effect of gas-liquid separation of the coolant.

[0040] It should be noted that the opening shape of the liquid inlet 213 can be circular, elliptical, or polygonal, etc. In the accompanying drawings of this application, the opening shape of the liquid inlet 213 is shown as circular. Setting the liquid inlet 213 as circular can improve the convenience of processing. The opening shape of the liquid outlet 215 can be circular, elliptical, or polygonal, etc. In the accompanying drawings of this application, the opening shape of the liquid outlet 215 is shown as circular. Setting the liquid outlet 215 as circular can improve the convenience of processing. The opening shape of the vent 217 can be circular, elliptical, or polygonal, etc. In the accompanying drawings of this application, the opening shape of the vent 217 is shown as circular. Setting the vent 217 as circular can improve the convenience of processing.

[0041] The angle between the first axis a of the inlet 213 and the first direction is greater than 0° and less than or equal to 90°, for example, it can be 0°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, or 90°.

[0042] In addition, the housing 211 has a radial direction. Along the radial direction, the first axis a of the liquid inlet 213 can intersect with the second axis b of the flow channel 216, or it can be spaced apart from the second axis b of the flow channel 216.

[0043] For example, along the radial direction, the first axis a of the inlet 213 and the second axis b of the flow channel 216 are spaced apart, that is, when the coolant enters the flow channel 216 through the inlet 213, it can deviate from the center of the flow channel 216 (located on the second axis b), thereby enabling the coolant to form a swirling flow in the flow channel 216, and using the effect of centrifugal force to improve the separation effect of coolant and refrigerant.

[0044] For example, in the radial direction, the first axis a of the inlet 213 intersects with the second axis b of the flow channel 216. That is, when the coolant enters the flow channel 216 through the inlet 213, it turns at the center of the flow channel 216 (located on the second axis b), causing the coolant to collide with the inner wall of the flow channel 216, thereby turbulenting the coolant and effectively separating the refrigerant mixed in the coolant.

[0045] Furthermore, in this application, the flow channel 216 can be a straight flow channel or a bent flow channel.

[0046] The entire body of the turbulence-disrupting component 28 can be disposed between the liquid inlet 213 and the liquid outlet 215, or a portion of the body can be disposed between the liquid inlet 213 and the liquid outlet 215.

[0047] In some embodiments of this application, such as Figure 10 and Figure 11As shown, the flow channel 216 is disposed within the housing 211 of the gas-liquid separator 21. The flow channel 216 is approximately cylindrical in shape, and its cross-section is circular. The second axis b of the flow channel 216 is aligned with the first direction. The first axis a of the liquid inlet 213 intersects with the second axis b of the flow channel 216, and the two axes are perpendicular to each other.

[0048] Specifically, based on the structure of the inlet 213 and outlet 215, the coolant forms an L-shaped liquid path as it flows from the inlet 213 to the outlet 215, thereby increasing the length of the liquid path and allowing the coolant to fully contact the turbulence-disrupting element 28. The turbulence-disrupting element 28 turbulents the coolant, allowing the refrigerant mixed in the coolant to be intercepted by the turbulence-disrupting element 28, thus facilitating the separation of the refrigerant from the coolant and improving the refrigerant separation effect. This reduces the possibility of refrigerant entering the room with the coolant, further improving the safety of users.

[0049] In some embodiments of this application, the inlet 213 has an opening area, which is a first area, and the flow channel 216 has a flow cross section (when the flow channel 216 is a cylindrical structure, the flow cross section is the cross-sectional area of ​​the flow channel 216), the area of ​​the flow cross section is a second area, and the second area is greater than the first area.

[0050] Specifically, the coolant flows into the flow channel 216 through the inlet 213. After passing through the baffle 28, the coolant flows towards the outlet 215. Since the area of ​​the flow cross section is larger than the opening area of ​​the inlet 213, the coolant can be slowed down as it enters the flow channel 216 through the inlet 213. The slowed-down coolant can increase its contact time with the baffle 28, thereby further improving the separation effect of the refrigerant by utilizing the baffle 28 to turbulent the coolant.

[0051] It should be understood that the flow deflector 28 is set in the flow channel 216. When the coolant flows to the outlet 215, it needs to pass through the flow deflector 28. The flow deflector 28 turbulents the coolant, so that the refrigerant mixed in the coolant (for example, the refrigerant exists in the form of bubbles) is intercepted by the flow deflector 28. The intercepted refrigerant escapes from the coolant, thereby achieving gas-liquid separation of the coolant.

[0052] The spoiler 28 can be a cage structure or a combination structure formed by multiple spoiler columns, etc.

[0053] In some embodiments of this application, such as Figure 7 and Figure 8As shown, the turbulence-disrupting component 28 includes a turbulence-disrupting body 282, on which a turbulence-disrupting channel is formed. The number of turbulence-disrupting channels is at least one. At least a portion of the body of the turbulence-disrupting body 282 is disposed between the liquid inlet 213 and the liquid outlet 215. The coolant entering through the liquid inlet 213 needs to pass through the turbulence-disrupting channel of the turbulence-disrupting body 282 and connect with the liquid outlet 215.

[0054] Specifically, the turbulence channel has a turbulence effect on the passing coolant, causing the refrigerant mixed in the coolant to collide as it flows along the turbulence channel, thereby escaping from the coolant. In this way, gas-liquid separation of the coolant can be achieved, reducing the possibility of refrigerant entering the room with the coolant, and thus improving the safety of users.

[0055] It should be noted that the number of spoiler channels can be one, two, three, four, five, six, seven, eight, nine, ten, etc. When there are multiple spoiler channels, they can be arranged in a regular or irregular manner.

[0056] In addition, when there are multiple turbulence channels, these channels can be set independently or interconnected.

[0057] In some embodiments of this application, such as Figure 7 and Figure 8 As shown, the spoiler 28 includes a spoiler body 282 and a retaining body 281, wherein the spoiler body 282 is disposed on the retaining body 281, and the retaining body 281 provides support for the spoiler body 282.

[0058] The main body 281 has a cylindrical structure and a third axis. It is positioned within the flow channel 216, and the third axis of the main body 281 coincides with the second axis b of the flow channel 216. A turbulence channel is located on the outside of the main body 281.

[0059] By setting up the retaining body 281, a carrier is provided to support the retaining body 281, so that the retaining body 281 has sufficient structural strength, thereby improving the structural strength and stability of the turbulence member 28, so that the turbulence member 28 can better realize the gas-liquid separation operation of the coolant.

[0060] It should be noted that by keeping the main body 281 as a cylindrical part, the weight of the main body 281 can be reduced, thereby reducing the weight of the gas-liquid separator 21. At the same time, by setting the main body 281 as a cylindrical part, the manufacturing cost of the gas-liquid separator 21 can be effectively reduced.

[0061] In some embodiments of this application, the gas-liquid separator 21 is used in the HVAC equipment 100 as an example, such as... Figures 5 to 7 ,as well as Figures 9 to 11 As shown, the second heat exchange component of the second heat exchange device 2 also includes an exhaust valve 22. The exhaust valve 22 is connected and fixed to the housing 211 of the gas-liquid separator 21. The exhaust valve 22 closes the exhaust port 217 of the housing 211. The refrigerant separated by the gas-liquid separator 21 needs to pass through the exhaust valve 22 before it can be discharged to the outside.

[0062] Specifically, an exhaust valve 22 is installed to control the discharge of refrigerant separated by the enterprise's separator, thereby reducing the overflow of coolant from the exhaust port 217.

[0063] It should be noted that in this application, the exhaust valve 22 includes a valve body 221, a valve cover 222, a valve core 223, an elastic element 224, a float 226, and a connecting rod assembly 225. The bottom of the valve body 221 is inserted into the exhaust port 217, and the valve body 221 and the exhaust port 217 are connected by a connecting structure (for example, the valve body 221 and the inner wall of the exhaust port 217 are connected by a threaded connection). A sealing structure (such as a sealing ring) can be provided at the connection. The bottom of the valve body 221 is provided with an air inlet, and the valve cover 222 is provided with an exhaust port. The valve body 221 has a receiving space inside, which is connected to the flow channel 216 of the housing 211 through the air inlet. 22 is threaded to the end of valve body 221 away from housing 211 (a sealing structure, such as a sealing ring, can be provided at the connection) and closes the opening of the accommodating space. Valve core 223 is movably mounted on valve cover 222 and can open or close the exhaust port. Elastic element 224 cooperates with valve core 223 and valve cover 222 respectively. Valve core 223 is connected to float 226 through connecting rod assembly 225 (connecting rod assembly 225 includes a first connecting rod and a second connecting rod. One end of the first connecting rod is movably connected to one end of valve core 223. The other end of the first connecting rod is hinged to one end of the second connecting rod. The other end of the second connecting rod is connected to float 226 (it can be fixedly connected or hinged, etc.)).

[0064] When there is no coolant in the flow channel 216 of the housing 211, the float 226 falls to the bottom of the receiving cavity under its own weight. The float 226 pulls down the valve core 223 through the connecting rod assembly 225, so that the valve core 223 overcomes the elastic force of the elastic element 224 and stays in the lowest position. At this time, the vent is open. When coolant enters the flow channel 216 through the inlet 213, the coolant enters the receiving space through the air inlet. The coolant entering the receiving cavity provides buoyancy to the float 226. Under the action of buoyancy, the float 226 rises to the top of the receiving space. The float 226 releases the downward force on the valve core 223. The rebound force of the elastic element 224 causes the valve core 223 to close the vent, thereby preventing coolant from overflowing through the vent.

[0065] After being turbulent by the baffle 28, the refrigerant in the coolant separates from the coolant and enters the containment space through the air inlet. It then floats to the space between the valve cover 222 and the float 226. As the amount of refrigerant increases, the gaseous refrigerant gradually squeezes the coolant out of the containment space into the flow channel 216. The float 226 descends as the coolant flows out. The descent of the float 226 pulls down the valve core 223 through the connecting rod assembly 225, causing the valve core 223 to overcome the elastic force of the elastic element 224 and move downward, thereby opening the vent hole so that the accumulated refrigerant can be discharged from the vent hole. After the refrigerant is discharged, the coolant continues to enter the containment cavity through the air inlet, and the float 226 floats up, causing the valve core 223 to close the vent hole again.

[0066] In addition, a guide hole 228 is provided on the float 226, and a guide post 227 is provided on the inner bottom surface of the valve seat. The guide post 227 is arranged in the vertical direction. The guide hole 228 is sleeved on the outside of the guide post. By utilizing the cooperation between the guide post 227 and the guide hole 227, the float 226 can rise or fall in the vertical direction, thereby reducing the possibility of the float 226 getting stuck, and thus achieving effective discharge of refrigerant and reducing coolant leakage.

[0067] In some embodiments of this application, taking the gas-liquid separator 21 used in the HVAC equipment 100 as an example, the second component includes an exhaust valve 22, such as... Figure 10 As shown, the gas-liquid separator 21 also has a limiting structure 2192 on its housing 211. The limiting structure 2192 is disposed within the flow channel 216 of the housing 211. There is at least one limiting structure 2192. The limiting structure 2192 is disposed between the exhaust port 217 and the liquid outlet 215 in the vertical direction (i.e., the first direction), and the limiting structure 2192 is spaced apart from the exhaust port 217. The flow-deflecting element 28 is assembled between the limiting structure 2192 and the exhaust port 217, and the retaining body 281 of the flow-deflecting element 28 abuts against the exhaust valve 22 disposed at the exhaust port 217 and the limiting structure 2192, respectively.

[0068] Specifically, during assembly, the deflector 28 is inserted into the flow channel 216 from the exhaust port 217, so that the retainer of the deflector 28 abuts against the limiting structure 2192. After the exhaust port 217 is assembled, the exhaust valve 22 abuts against the retainer. In this way, the deflector 28 can be fixed. Fixing the deflector 28 by abutting can improve the fixing strength of the deflector 28 and reduce the shaking of the deflector 28, thereby improving the deflection effect of the deflector 28 on the coolant, and thus improving the gas-liquid separation effect of the gas-liquid separator 21 on the coolant.

[0069] It should be noted that the limiting structure 2192 can be a boss or rib formed on the inner wall of the flow channel 216.

[0070] In addition, the number of limit structures 2192 can be one, two, three, four, five, six, seven, eight, nine, etc.

[0071] In some embodiments of this application, such as Figure 10 As shown, there are multiple limiting structures 2192, which are spaced apart along the circumferential direction of the flow channel 216.

[0072] Specifically, along the first direction, one end of the retaining body 281 of the deflector 28 abuts against the limiting structure 2192, and the other end abuts against the exhaust valve 22. By setting multiple limiting structures 2192, the limiting effect on the deflector 28 is improved, thereby improving the positional accuracy of the deflector 28, so as to effectively achieve the effect of gas-liquid separation of coolant using the deflector 28.

[0073] It should be noted that multiple limiting structures 2192 are set at intervals along the circumferential direction, and the intervals can be set at equal intervals or unequal intervals.

[0074] In addition, in this application, along the first direction (i.e., the direction of the second axis b), the liquid inlet 213 is disposed between the liquid outlet 215 and the exhaust port 217, and the flow-dispersing member 28 is respectively disposed against the limiting structure 2192 and the exhaust valve 22. At this time, along the first direction, the flow-dispersing member 28 covers the areas of the flow channel 216 located above and below the liquid inlet 213, so that the flow-dispersing member 28 can further contact the coolant, increasing the contact area between the flow-dispersing member 28 and the coolant, further increasing the effect of the flow-dispersing member 28 on the coolant, and further improving the effect of gas-liquid separation of the coolant.

[0075] In some embodiments of this application, such as Figure 8 As shown, the deflector 28 includes a deflector body 282 and a retaining body 281. The deflector body 282 includes a first rod 283 and a second rod 284. There are multiple first rods 283, which are respectively disposed on the outer peripheral surface of the retaining body 281 and are radially distributed on the outer peripheral surface of the retaining body 281.

[0076] The second rod 284 is spirally disposed on the outside of the holding body 281 and is connected to each of the first rods 283. The second rod 284 is spaced apart from the outer peripheral surface of the holding body 281, and the first rods 283 and the second rod 284 form a cage structure.

[0077] Specifically, in the cage-like structure of the turbulence-inducing body 282, the turbulence-inducing channel formed by the space between the first rod 283 and the second rod 284 is set in the flow channel 216. The first rod 283 and the second rod 284 are used to turbulent the coolant, so that the refrigerant mixed in the coolant is intercepted, thereby realizing the gas-liquid separation of the coolant.

[0078] The cage-like turbulence-dispersing body 282 has a simple structure and a large contact area with the coolant, which can effectively improve the gas-liquid separation effect of the coolant.

[0079] It should be noted that the turbulence-disrupting body 282 and the retaining body 281 can be metal or non-metal. When the turbulence-disrupting body 282 and the retaining body 281 are metal (e.g., stainless steel), the metal parts have high structural strength, which can reduce the deformation caused by coolant impact, thereby effectively maintaining the gas-liquid separation effect of the coolant.

[0080] In addition, the first rod 283 can be a straight rod or a bent rod. For example, the first rod 283 is a U-shaped rod, with both ends of the U-shaped rod connected to the outer circumferential surface of the retainer, and the second rod 284 is connected to the bottom of the U-shaped rod (the connection method can be, for example, welding).

[0081] In addition, the second rod 284 can be a one-piece structure or a split structure.

[0082] In some embodiments of this application, such as Figure 7 As shown, a reserved interface 219 is also provided on the housing 211 of the gas-liquid separator 21. The number of reserved interfaces 219 is at least one, and the reserved interface 219 has a fourth axis, which is set at an angle to the second direction. A sealing element 29 is provided on each reserved interface 219 in a detachable manner to seal the reserved interface 219.

[0083] Specifically, when additional components are needed, the component can be directly connected to the reserved interface 219 after the sealing component 29 is removed. The reserved interface 219 improves the versatility of the gas-liquid separator 21.

[0084] It should be noted that the opening shape of the reserved interface 219 can be circular, elliptical, or polygonal. In the accompanying drawings of this application, the opening shape of the reserved interface 219 is shown as circular. Setting the reserved interface 219 as circular can improve the convenience of processing.

[0085] The angle between the fourth axis of the reserved interface 219 and the first direction is greater than 0° and less than or equal to 90°. For example, it can be 0°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, or 90°.

[0086] In addition, the housing 211 has a radial direction, and along the radial direction, the fourth axis of the reserved interface 219 can intersect with the second axis b of the flow channel 216, or it can be spaced apart from the second axis b of the flow channel 216.

[0087] In addition, the number of reserved interfaces 219 can be one, two, three, four, five, six, seven or eight, etc.

[0088] When there are multiple reserved interfaces 219, the multiple reserved interfaces 219 can be spaced apart along the first direction or spaced apart along the circumferential direction of the housing 211.

[0089] In some embodiments of this application, such as Figure 12 As shown, the housing 211 is provided with a number of reserved connectors 218 that are the same as the number of reserved interfaces 219, and a reserved interface 219 is provided on each reserved connector 218.

[0090] The sealing component 29 includes a limiting body 292 and a sealing body 291. The sealing body 291 has a first state and a second state. In the first state, the sealing body 291 seals the reserved interface 219. The limiting body 292 cooperates with the sealing body 291 and the reserved connector 218 respectively to fix the sealing body 291. In the second state, the sealing body 291 is separated from the reserved interface 219.

[0091] Taking the gas-liquid separator 21 used in the HVAC equipment 100 as an example, the reserved interface 219 is used for the connection of the functional components of the second component 20, and the limiting body 292 cooperates with the functional components and the reserved connector 218 respectively to fix the functional components.

[0092] Specifically, the reserved connector 218 protrudes from the outer surface of the housing 211, and the reserved interface 219 is opened at the end of the reserved connector 218 away from the housing 211. By setting the reserved connector 218, the convenience of assembly can be improved, and the efficiency of assembly can be improved.

[0093] In addition, the reserved connector 218 can be an integral structure with the housing 211 or a separate structure (the two are fixedly connected, and the connection method includes but is not limited to bonding or welding).

[0094] In this application, the sealing body 291 is a sealing plug, which is installed in the reserved interface 219 by insertion and removal. The limiting body 292 is a retaining ring (C-type retaining ring). A socket is provided on the side of the reserved connector 218, which communicates with the inside of the reserved connector 218. Part of the retaining ring is inserted into the inside of the reserved connector 218 through the retaining hole and engages with the sealing connector, so that the sealing connector is fixed in the reserved connector 218.

[0095] In some embodiments of this application, the gas-liquid separator 21 is used in the HVAC equipment 100 as an example, such as... Figures 5 to 7 , Figure 9 , Figure 10 as well as Figure 12 As shown, the second component includes a pressure relief valve 23 among its multiple functional parts. The pressure relief valve 23 is connected to a reserved connector 218. At the reserved connector 218 connected to the pressure relief valve 23, the sealing body 291 switches from a first state to a second state. The pressure relief valve 23 is inserted into the reserved connector 218 and connected to the flow channel 216 through the reserved interface 219. The limiting body 292 cooperates with the reserved connector 218 and the pressure relief valve 23 respectively to fix the pressure relief valve 23.

[0096] Specifically, the flow channel 216 has a radial direction, and along this radial direction, the inlet 213 is positioned opposite to the pressure relief valve 23. The coolant in the flow channel 216 has a certain pressure, and the pressure relief valve 23 has a preset opening pressure. When the pressure in the flow channel 216 reaches the opening pressure of the pressure relief valve 23, the pressure relief valve 23 automatically opens, allowing the coolant in the flow channel 216 to be released. At the same time, the refrigerant mixed in the coolant is also released, thereby reducing the possibility of refrigerant entering the room with the coolant and further improving user safety.

[0097] In addition, the pressure relief valve 23 is inserted into the reserved connector 218 through the reserved interface 219 and fixed by the limiting body 292. In this way, the pressure relief valve 23 can be quickly assembled, which improves the assembly efficiency.

[0098] A sealing structure (such as a sealing ring) can be installed at the joint between the pressure relief valve 23 and the reserved connector 218 to reduce leakage at the joint.

[0099] In some embodiments of this application, the gas-liquid separator 21 is used in the HVAC equipment 100 as an example, such as... Figures 5 to 7 , Figure 9 and Figure 10As shown, a first connector 212 protrudes from the outer peripheral surface of the housing 211, and a liquid inlet 213 is provided on the end of the first connector 212 away from the housing 211. A first flange 2190 is provided on the first connector 212. In the second component 20 of the second heat exchange device 2, a first clamp 25 and a liquid inlet pipe 24 are also included. A second flange 241 is provided on the outer peripheral surface of the liquid inlet pipe 24. The first connector 212 is inserted into the liquid inlet pipe 24, and the first flange 2190 abuts against the second flange 241. The first clamp 25 cooperates with the first flange 2190 and the second flange 241 respectively to fix the first connector 212 and the liquid inlet pipe 24.

[0100] Specifically, the first clamp 25 includes two opposing first clamping arms, which are elastically spaced apart. Each first clamping arm has a first locking hole, and these holes are opposite to each other. A first clamping space is formed between the two first clamping arms, and this first clamping space communicates with the outside at a first opening position.

[0101] When it is necessary to fix the first connector 212 and the inlet pipe 24, the end of the inlet pipe 24 with the second flange 241 is inserted into the first connector 212, so that the first flange 2190 and the second flange 241 abut against each other. The external force drives the opening size of the first opening position to increase, and it is sleeved on the outside of the first flange 2190 and the second flange 241, so that the first flange 2190 and the second flange 241 respectively enter the first clamping space through the first opening position. When the external force is released, the two first clamping arms are reset, the size of the first opening is reset, and part of the structure of the first flange 2190 and the second flange 241 protrudes through the first card hole to clamp the first space. The two first clamping arms are clamped on the outside of the inlet pipe 24 and the first connector 212 to fix the inlet pipe 24.

[0102] The above structure is simple and facilitates the disassembly and assembly of the liquid inlet pipe 24, which can improve the convenience of the disassembly and assembly process.

[0103] In addition, a sealing structure such as a sealing ring is provided at the insertion position of the liquid inlet pipe 24 and the liquid inlet structure to reduce the occurrence of coolant leakage.

[0104] In some embodiments of this application, the gas-liquid separator 21 is used in the HVAC equipment 100 as an example, such as... Figures 5 to 7 , Figure 9 and Figure 10As shown, a second connector 214 protrudes from the outer peripheral surface of the housing 211, and a liquid outlet 215 is provided on the end of the second connector 214 away from the housing 211. A third flange 2191 is provided on the second connector 214. In the second component 20 of the second heat exchange device 2, a second clamp 26 and a liquid outlet pipe 27 are also included. A fourth flange 271 is provided on the outer peripheral surface of the liquid outlet pipe 27. The second connector 214 is inserted into the liquid outlet pipe 27, and the third flange 2191 abuts against the fourth flange 271. The second clamp 26 is engaged with the third flange 2191 and the fourth flange 271 respectively to fix the second connector 214 and the liquid outlet pipe 27.

[0105] Specifically, the second clamp 26 includes two opposing second clamping arms, which are elastically spaced apart. Each second clamping arm has a second locking hole, and these holes are opposite to each other. A second clamping space is formed between the two second clamping arms, and this second clamping space communicates with the outside at a second opening position.

[0106] When it is necessary to fix the second connector 214 and the outlet pipe 27, the end of the outlet pipe 27 with the third flange 2191 is inserted into the second connector 214, so that the third flange 2191 and the fourth flange 271 abut against each other. The external force drives the opening size of the second opening position to increase, and it is sleeved on the outside of the third flange 2191 and the fourth flange 271, so that the third flange 2191 and the fourth flange 271 enter the second clamping space through the second opening position respectively. When the external force is released, the two second clamping arms are reset, the size of the second opening is reset, and part of the structure of the third flange 2191 and the fourth flange 271 protrudes from the first clamping space through the second card hole. The two second clamping arms are clamped on the outside of the outlet pipe 27 and the second connector 214 to fix the outlet pipe 27.

[0107] The above structure is simple and facilitates the disassembly and assembly of the liquid outlet tube 27, which can improve the convenience of the disassembly and assembly process.

[0108] In addition, a sealing structure such as a sealing ring is provided at the insertion position of the outlet pipe 27 and the second connector 214 to reduce the occurrence of coolant leakage.

[0109] like Figures 1 to 12As shown, a second aspect of this application discloses a heating, ventilation, and air conditioning (HVAC) system 100, which includes an indoor unit and an outdoor unit. The indoor unit and the outdoor unit are connected to form a heat exchange system. The heat exchange system includes a first heat exchange device and a second heat exchange device. The first heat exchange device is located in the outdoor unit and is used to circulate refrigerant, while the second heat exchange device is used to circulate coolant. The second heat exchange device includes a first component and a second component. The first component is located indoors and exchanges heat with the indoor unit, while the second component is located in the outdoor unit and connected to the first heat exchange device, enabling the coolant to exchange heat with the refrigerant. The second component includes a gas-liquid separator, which is used to separate the coolant entering the indoor unit.

[0110] According to this application, when the heat exchange system of the HVAC equipment 100 is running, the refrigerant in the first heat exchange device 1 exchanges heat with the coolant through the second component 20 of the second heat exchange device 2. After heat exchange, the coolant exchanges heat in the room through the first component 10 to meet the needs of indoor temperature regulation. When refrigerant leaks and flows with the coolant, when the coolant flows through the gas-liquid separator 21, the coolant carrying the refrigerant enters the flow channel 216 through the inlet 213 and flows out through the outlet 215. During the flow of the coolant towards the outlet 215, the turbulence member 28 turbulents the coolant, causing the refrigerant mixed in the coolant to separate from the coolant. The separated coolant flows downward through the outlet 215, and the separated refrigerant is discharged upward through the exhaust port 217. In this way, the situation of refrigerant entering the room can be reduced, thereby reducing the safety hazards during user operation.

[0111] In this application, the HVAC equipment 100 includes a housing 3, which forms a receiving space. The first heat exchange device 1 and the second component 20 of the second heat exchange device 2 are disposed in the receiving space. The housing 3 provides protection for the first heat exchange device 1 and the second component 20, thereby reducing the adverse effects of the external environment on the first heat exchange device 1 and the second component 20.

[0112] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
