Description

Technical Field

[0001] The present application relates to the field of refrigeration technology, and specifically to a liquid collecting bag of a HVAC equipment and a HVAC equipment. Background Art

[0002] In the HVAC equipment of the related technology, the liquid intake structure of the economizer and the liquid intake structure of the compressor are independently welded and connected to the shell of the condenser. This requires the provision of multiple liquid intake ports on the condenser, which affects the structural strength of the condenser shell and the production efficiency of the HVAC equipment. In addition, the coolant flow rate inside the shell is fast and the diameter of the liquid intake pipe is small, which makes it easy for the liquid intake pipe to fail to extract the coolant and the liquid intake process is unstable.

[0033] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0034] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] Combination Figure 1 and Figure 2 According to the liquid collection bag 10 of the HVAC equipment 100 of the embodiment of the present application, it includes a main body 11, a first liquid collection pipe 12 and a second liquid collection pipe 13. The main body 11 has a connecting port 111 for connecting to the condenser and a accommodating cavity 112 connected to the connecting port 111. The first liquid collection pipe 12 is connected to the main body 11 and communicates with the accommodating cavity 112. The second liquid collection pipe 13 is connected to the main body 11 and communicates with the accommodating cavity 112. The first liquid collection pipe 12 is used to connect to the economizer, and the second liquid collection pipe 13 is used to connect to the compressor.

[0036] The liquid collecting bag 10 of the HVAC equipment 100 of the present application includes a main body 11, a first liquid collecting pipe 12 and a second liquid collecting pipe 13. Since the first liquid collecting pipe 12 and the second liquid collecting pipe 13 are connected to the liquid collecting bag 10, which is used for collecting liquid from the compressor and the economizer, the liquid collecting bag 10 can be produced in advance, and then the liquid collecting bag 10 is connected to the condenser 20 to realize collecting liquid from the collecting pipe, and there is no need to respectively open collecting holes for the first liquid collecting pipe 12 and the second liquid collecting pipe 13 on the condenser 20. In addition, when the liquid collecting bag 10 is installed on the condenser 20, the coolant in the condenser 20 can enter the accommodating chamber 112. At this time, the accommodating chamber 112 contains coolant, and the flow rate of the coolant in the accommodating chamber 112 is relatively small compared to the flow rate in the condenser 20. The first liquid collecting pipe 12 and the second liquid collecting pipe 13 can collect liquid from the accommodating chamber 112, which facilitates the coolant to pass into the first liquid collecting pipe 12 and the second liquid collecting pipe 13, thereby further improving the stability of the liquid collecting process of the collecting pipe.

[0037] like Figure 2 As shown, in order to further improve the stability of the liquid collection bag 10, in some embodiments of the present application, a sedimentation area 113 is constructed at the lower part of the accommodating chamber 112, and the liquid intake port of the first liquid intake tube 12 and the liquid intake port of the second liquid intake tube 13 are both higher than the sedimentation area 113.

[0038] It is understandable that the pipelines of HVAC equipment are usually welded, and the coolant is easily mixed with impurities such as welding slag when it circulates. When the coolant flows through the main body 11, the welding slag and other impurities in the coolant are deposited in the sedimentation area 113 at the lower part of the accommodating cavity 112 due to the action of gravity, and the liquid intake port of the first liquid collection pipe 12 and the liquid intake port of the second liquid collection pipe 13 are both higher than the sedimentation area 113. When the first liquid collection pipe 12 and the second liquid collection pipe 13 are taking liquid, the welding slag will be deposited in the sedimentation area 113, and the welding slag and other impurities deposited in the sedimentation area 113 are difficult to enter the first liquid collection pipe 12 and the second liquid collection pipe 13 from the liquid intake port, thereby preventing the welding slag and other impurities from clogging the first liquid collection pipe 12 and the second liquid collection pipe 13, and also preventing the welding slag and other impurities from easily circulating with the pipelines of the HVAC equipment and thereby clogging the pipelines.

[0039] like Figure 2As shown, in some embodiments of the present application, the liquid intake port of the first liquid intake tube 12 is staggered with the deposition area in the axial direction, and the liquid intake port of the first liquid intake tube 12 is staggered with the connecting port 111 in the axial direction; the liquid intake port of the second liquid intake tube 13 is staggered with the deposition area in the axial direction, and is staggered with the connecting port 111.

[0040] It should be noted that “the liquid intake port of the first liquid intake tube 12 is offset from the sedimentation area in the axial direction” means that the liquid intake port of the first liquid intake tube 12 is not opposite to the sedimentation area in the axial direction; similarly, “the liquid intake port of the first liquid intake tube 12 is offset from the connecting port 111 in the axial direction” means that the liquid intake port of the first liquid intake tube 12 is not opposite to the connecting port 111 in the axial direction; “the liquid intake port of the second liquid intake tube 13 is offset from the sedimentation area in the axial direction” means that the liquid intake port of the second liquid intake tube 13 is not opposite to the sedimentation area in the axial direction; “the liquid intake port of the second liquid intake tube 13 is offset from the connecting port 111 in the axial direction” means that the liquid intake port of the second liquid intake tube 13 is not opposite to the connecting port 111 in the axial direction.

[0041] It can be understood that impurities such as welding slag in the coolant can be fully deposited in the deposition area 113 in the accommodating chamber 112. Since the liquid collection port is not opposite to the deposition area 113 in the axial direction, it is difficult for the liquid collection port to absorb impurities such as welding slag in the deposition area 113 when taking liquid. The liquid collection port is also not opposite to the connecting port 111 in the axial direction. It is difficult for the liquid collection port to absorb the coolant in the accommodating chamber 112 from which impurities such as welding slag have not been separated when taking liquid. This prevents impurities such as welding slag mixed in with the coolant after it enters the connecting port 111 from entering the liquid collection port due to liquid absorption.

[0042] In some embodiments of the present application, the main body 11 can be configured to be tubular, wherein: the axis of the liquid intake port of the first liquid intake tube 12 can be configured to have an angle greater than 20° with the axis of the main body 11; the axis of the liquid intake port of the second liquid intake tube 13 can be configured to have an angle greater than 20° with the axis of the main body 11. The axis of the main body 11 can be configured to extend in the up-down direction. It can be understood that since there is an angle between the axis of the liquid intake port of the first liquid intake tube 12 and the axis of the main body 11, the liquid intake port of the first liquid intake tube 12 can be partially extended into the accommodating chamber 112 to facilitate liquid collection, and the difficulty of impurities entering the second liquid intake tube 13 is increased by avoiding the liquid intake port of the first liquid intake tube 12 from being opposite to the deposition area 113 or opposite to the connecting port 111. Similarly, there is an angle between the axis of the liquid intake port of the second liquid intake tube 13 and the axis of the main body 11, and the liquid intake port of the second liquid intake tube 13 can be partially extended into the accommodating chamber 112 for liquid intake. By avoiding the liquid intake port of the second liquid intake tube 13 being opposite to the sedimentation area 113 or the connecting port 111, the difficulty of impurities entering the second liquid intake tube 13 is increased.

[0043] like Figure 2As shown, in other embodiments of the present application, the connecting port 111 is opposite to the deposition area 113 in the up-down direction, the axis of the liquid intake port of the first liquid intake tube 12 is perpendicular to the up-down direction, and the axis of the liquid intake port of the second liquid intake tube 13 is perpendicular to the up-down direction.

[0044] It is understandable that when the impurities such as welding slag mixed with the coolant enter the accommodating chamber 112 from the connecting port 111, they can be deposited to the deposition area 113 opposite to the connecting port 111 by gravity, thereby improving the deposition effect of impurities such as welding slag. At the same time, compared with the above-mentioned embodiment, the angle between the axis of the liquid outlet of the first liquid taking pipe 12 and the vertical direction is greater than 20° and less than 90°. Since the axis of the liquid outlet of the first liquid taking pipe 12 is perpendicular to the vertical direction, the suction direction of the first liquid taking pipe 12 when taking liquid is perpendicular to the vertical direction, and impurities such as welding slag are more difficult to be sucked into the liquid outlet from the deposition area 113 by the first liquid taking pipe 12 along the vertical direction. Similarly, since the axis of the liquid outlet of the second liquid taking pipe 13 is perpendicular to the vertical direction, the suction direction of the second liquid taking pipe 13 when taking liquid is perpendicular to the vertical direction, and impurities such as welding slag are more difficult to be sucked into the liquid outlet from the deposition area 113 by the second liquid taking pipe 13 along the vertical direction.

[0045] It can also be understood that if there is an angle between the axis of the liquid intake port and the axis of the main body 11, impurities such as welding slag may contact the liquid intake port of the first liquid intake tube 12 and enter the first liquid intake tube 12 during the deposition process. Since the axis of the liquid intake port of the first liquid intake tube 12 is perpendicular to the up-down direction, it is difficult for impurities such as welding slag to fall into the liquid intake port of the first liquid intake tube 12 during the deposition process. Similarly, since the axis of the liquid intake port of the second liquid intake tube 13 is perpendicular to the up-down direction, it is difficult for impurities such as welding slag to fall into the liquid intake port of the second liquid intake tube 13 during the deposition process. When the first and second liquid intake tubes 12 and 13 take liquid, it is difficult to absorb the coolant from which the welding slag and other impurities have not been separated in the accommodating chamber 112, and it is also difficult to absorb the welding slag and other impurities in the deposition area 113, further avoiding the welding slag and other impurities from clogging the first and second liquid intake tubes 12 and 13.

[0046] like Figure 2 As shown, in some embodiments of the present application, the main body 11 includes a blocking piece 114 , which is disposed at the bottom of the deposition area 113 , and the blocking piece 114 is used to open and close the deposition area 113 .

[0047] It is understandable that when the sealing member 114 opens the deposition area 113, it is used to clean impurities such as welding slag in the deposition area 113. When the sealing member 114 closes the deposition area 113, it is used for coolant to enter the main body 11, and impurities such as welding slag are deposited in the deposition area 113 due to gravity.

[0048] In some embodiments of the present application, the plugging member 114 and the deposition area 113 are configured to be bolted, snap-fitted or flanged, etc. The plugging member 114 is removable or disposed at the bottom of the deposition area 113 to open and close the deposition area 113. It should be noted that the assembly method between the plugging member 114 and the deposition area 113 can be set according to actual needs. The assembly method of the plugging member 114 and the deposition area 113 is described in this application, but this is not a limitation on the scope of protection of this application. For example, the plugging member 114 can be configured to have a peripheral edge that fits tightly against the peripheral wall of the deposition area 113; the plugging member 114 can also be configured to have a peripheral edge that covers the peripheral wall of the deposition area 113, etc. In addition, as described in the following embodiments, the plugging member 114 in this application can also be configured in other forms.

[0049] Combination Figure 3 and Figure 4 In some embodiments of the present application, the main body 11 includes a connecting pipe 115 and a sealing plate 116. The connecting pipe 115 extends in the up-down direction. A accommodating cavity 112 is constructed in the connecting pipe 115. The connecting port 111 is arranged at the upper end of the connecting pipe 115. The sealing plate 116 closes the lower end of the connecting pipe 115.

[0050] It can be understood that since the connecting pipe 115 extends in the up-down direction and constitutes the peripheral wall of the main body 11, the sealing plate 116 closes the lower end of the connecting pipe 115. At this time, the connecting pipe 115 and the sealing plate 116 construct a accommodating chamber 112 for storing coolant and a deposition area 113 at the lower part of the accommodating chamber 112 for depositing impurities such as welding slag, and the connecting port 111 is arranged at the upper end of the connecting pipe 115 to facilitate the introduction of coolant.

[0051] like Figure 3 As shown, in some embodiments of the present application, a first interface and a second interface are provided on the peripheral wall of the connecting pipe 115, and the first interface and the second interface are both separated from the sealing plate 116 by a predetermined distance, and the liquid intake port of the first liquid collection tube 12 is connected to the first interface, and the liquid intake port of the second liquid collection tube 13 is connected to the second interface.

[0052] It can be understood that the liquid inlet of the first liquid collection tube 12 is connected to the first interface, and the liquid inlet of the second liquid collection tube 13 is connected to the second interface, so that the first liquid collection tube 12 and the second liquid collection tube 13 are connected to the connecting pipe 115. At the same time, since the first interface and the second interface are both spaced apart from the sealing plate 116, the liquid inlet of the first liquid collection tube 12 and the liquid inlet of the second liquid collection tube 13 are also at a certain distance from the sealing plate 116, so that it is difficult for the first liquid collection tube 12 and the second liquid collection tube 13 to absorb impurities such as welding slag in the deposition area 113 when taking liquid.

[0053] In some other embodiments of the present application, the first interface and the second interface are disposed on opposite sides of the connecting pipe 115 .

[0054] It can be understood that when the first interface and the second interface are arranged on opposite sides of the connecting pipe 115, the distance between the liquid collection areas of the first liquid collection tube 12 and the second liquid collection tube 13 when they are collecting liquid is relatively maximized, thereby reducing the stability of the liquid collection process that is affected by each other when the two are collecting liquid at the same time, and further improving the stability of the liquid collection process of the first liquid collection tube 12 and the second liquid collection tube 13.

[0055] In some other embodiments of the present application, the angle between the first interface and the second interface may be set to be between 10° and 180°.

[0056] Furthermore, in some other embodiments of the present application, the angle between the first interface and the second interface is set to 90°.

[0057] like Figure 2 As shown, in some embodiments of the present application, the upper end of the connecting pipe 115 is opened to form a connecting port 111. The connecting port 111 is used to contact the condenser 20, which is convenient for welding or other fixed connection. When the coolant enters the main body 11 through the connecting port 111, it not only quickly fills the accommodating cavity 112 due to gravity, but also separates impurities such as welding slag mixed with the coolant due to gravity and deposits them in the deposition area 113.

[0058] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, the upper end of the connecting pipe 115 is configured to be in an arc shape that matches the outer surface shape of the condenser 20 .

[0059] It can be understood that the arc shape of the upper end of the connecting pipe 115 is adapted to the outer surface shape of the condenser 20 , and after the connecting pipe 115 contacts the condenser 20 , the contact surface fits better and is convenient for welding or other fixed connection.

[0060] In some embodiments of the present application, the sealing plate 116 is disposed on the inner side of the connecting pipe 115, and the periphery of the sealing plate 116 is sealed with the peripheral wall of the connecting pipe 115; the sealing plate 116 is welded, integrally formed, or sealed with the connecting pipe 115. The sealing plate 116 and the connecting pipe 115 are tightly connected by the above-mentioned simple assembly method to form the accommodating chamber 112 and the deposition area 113 at the lower part of the accommodating chamber 112.

[0061] The sealing plate 116 and the connecting pipe 115 in the present application can be assembled together in different ways. For example, the sealing plate 116 and the connecting pipe 115 can be welded, integrally formed, sealed, etc. The assembly method between the sealing plate 116 and the connecting pipe 115 can be set according to actual needs. The assembly method of the sealing plate 116 and the connecting pipe 115 is explained in some detail in the present application, but this does not limit the scope of protection of the present application.

[0062] In other embodiments of the present application, the sealing plate 116 is disposed on the inner side of the pipe 115, and the periphery of the sealing plate 116 cooperates with the peripheral wall of the pipe 115, and the sealing plate 116 and the pipe 115 are configured to be threaded or snap-fitted. It is understandable that the sealing plate 116 can be freely disassembled and matched with the pipe 115, and the sealing plate 116 and the pipe 115 cooperate to construct the closed accommodating chamber 112 and the deposition area 113, and the disassembly of the sealing plate 116 can be used to clean impurities such as welding slag deposited on the sealing plate 116.

[0063] like Figure 4 As shown, in some embodiments of the present application, the sealing plate 116 has an outlet, and the main body 11 further includes a blocking member 114, which is used to block and open the outlet. It can be understood that when the blocking member 114 opens the outlet, it is used to clean impurities such as welding slag in the deposition area 113, and when the blocking member 114 closes the outlet, it is used to prevent the coolant from flowing out of the outlet when entering the main body 11, and at the same time, impurities such as welding slag are deposited on the sealing plate 116 under the influence of gravity.

[0064] In some embodiments of the present application, the plugging member 114 is threadedly connected, snap-fitted or flanged to the sealing plate 116. It is understandable that the plugging member 114 and the sealing plate 116 are connected in the above manner to open the outlet to clean up the impurities such as welding slag, and the outlet can also be blocked to construct the accommodating chamber 112 and the deposition area 113 to store coolant and deposit impurities such as welding slag.

[0065] In some embodiments of the present application, the plugging member 114 is configured as a screw plug, and the sealing plate is configured with an opening having threads. It is understandable that when the screw plug is screwed into the threads of the sealing plate opening, the deposition area is closed.

[0066] In other embodiments of the present application, the blocking member 114 is configured as a flange cover, and the sealing plate is provided with a circular hole that matches the flange cover. It is understandable that the flange cover is provided at the lower end of the outlet, and the flange cover is connected to the sealing plate by a flange connection to open and block the outlet.

[0067] like Figure 1As shown, the connecting pipe 115 can be set to a circular tube shape, one end of which is used to dock with the shell of the condenser 20, and the end portion is set to a shape that is compatible with the shell of the condenser 20, the first liquid collection pipe 12 and the second liquid collection pipe 13 are connected to the peripheral wall of the connecting pipe 115, and can be set to extend in a direction perpendicular to the axis of the connecting pipe 15, wherein the radial dimension of the first liquid collection pipe 12 and the radial dimension of the second liquid collection pipe 13 can be the same or different. The other end of the connecting pipe is closed by a sealing plate 116, and the sealing plate 116 can be configured to be embedded in the connecting pipe 115, and the periphery of the sealing plate 116 can be sealed with the connecting pipe 115, welded or integrally formed, etc. In addition, the first liquid collection tube 12 and the second liquid collection tube 13 can be configured to have an angle with a predetermined angle, and the angle between the first liquid collection tube 12 and the second liquid collection tube 13 can be set to be between 10° and 180°, for example, the angle between the first liquid collection tube 12 and the second liquid collection tube 13 is set to 90°.

[0068] The HVAC equipment 100 according to the present application is briefly described below.

[0069] Combination Figures 5 to 7 According to the HVAC equipment 100 of the embodiment of the present application, it includes a condenser 20 and the liquid collecting bag 10 of the HVAC equipment mentioned above, and the connecting port 111 is connected to the condenser 20.

[0070] The HVAC equipment 100 of the embodiment of the present application connects the liquid collecting bag 10 to the condenser 20. The coolant enters the liquid collecting bag 10 through the connecting port 111, and the liquid collection pipe then stably draws liquid from the liquid collecting bag 10. The liquid collection process is highly stable and there is no need to open an economizer liquid collection hole.

[0071] In some embodiments of the present application, the liquid collecting bag 10 is welded to the shell of the condenser 20 .

[0072] In some embodiments of the present application, the liquid collecting bag 10 is connected to the bottom of the shell of the condenser 20 .

[0073] The liquid collecting bag 10 and the condenser 20 in the present application can be assembled together in different ways. For example, the liquid collecting bag 10 and the condenser 20 body can be welded, interference fit, snap-connected, bolted, etc., and the assembly method between the liquid collecting bag 10 and the condenser 20 can be set according to actual needs. The assembly method of the liquid collecting bag 10 and the condenser 20 is explained in some detail in the present application, but this is not a limitation on the scope of protection of the present application.

[0074] Combination Figure 1 , Figure 6 and Figure 8In the HVAC equipment 100 of the embodiment of the present application, the liquid collecting bag 10 is connected to the condenser 20, and the coolant enters the liquid collecting bag 10 through the connection port 111. A part of the coolant in the liquid collecting bag 10 is taken from the liquid collecting bag 12 to the economizer 30 through the first liquid taking pipe 12, and another part of the coolant is taken from the second liquid taking pipe 13 to the compressor 40. The stability of the liquid taking process is relatively high, and there is no need to open the liquid taking hole of the economizer. Figure 8 As shown, the coolant enters the liquid collecting bag 10 through the connection port 111, and the coolant in the liquid collecting bag 10 flows through the compressor 40 and then flows back to the condenser 20, or flows through the economizer 30 and the compressor 40 and then flows back to the condenser 20 from the compressor 40, thereby realizing the circulation of the coolant in the HVAC equipment 100.
