Technical Field

[0001] The utility model relates to the technical field of air conditioning, and in particular to an air conditioning outdoor unit and a heating and ventilation device. Background Art

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] In the air-conditioning outdoor unit, a filter is usually installed between the four-way valve and the stop valve.

[0042] The utility model provides an air-conditioning outdoor unit, which comprises a multi-way valve, at least one stop valve and at least one filter, wherein one valve port of the multi-way valve is connected to one inlet and outlet of the stop valve through a refrigerant pipeline, and the other inlet and outlet of the stop valve is connected to one inlet and outlet of the filter through a refrigerant pipeline, so that the refrigerant medium can flow along one valve port of the multi-way valve to the stop valve and then to the filter, and the refrigerant medium can also flow along the filter to the stop valve and then flow into one valve port of the multi-way valve.

[0043] At least one valve port of the multi-way valve is connected in series with a stop valve and a filter through a refrigerant pipeline, and the filter is arranged on a side of the stop valve away from the valve port.

[0044] In the air-conditioning outdoor unit of the utility model, the pipelines connected to different valve ports of the multi-way valve can be arranged in a more reasonable path. Since a filter is no longer arranged between the multi-way valve and the stop valve, the pipelines connected to different valve ports of the multi-way valve no longer need to avoid the filter between the multi-way valve and the stop valve, thereby reducing the length of multiple refrigerant pipelines. In addition, the arrangement of multiple refrigerant pipelines is simpler, which is convenient for subsequent maintenance and repair.

[0045] The air-conditioning outdoor unit of the utility model reduces the lengths of a plurality of refrigerant pipelines in the air-conditioning outdoor unit, thereby simplifying its structure and reducing the cost of the air-conditioning outdoor unit, thereby improving the product competitiveness of the air-conditioning outdoor unit.

[0046] In the air-conditioning outdoor unit of the utility model, at least one filter is arranged in the refrigerant pipeline assembly, which is used to filter impurities formed in the refrigerant pipeline assembly when the air-conditioning outdoor unit is running, so as to prevent the impurities from entering the stop valve, multi-way valve, or other equipment such as a compressor or a heat exchanger of the air-conditioning outdoor unit.

[0047] The air-conditioning outdoor unit of the utility model is provided with at least one stop valve in the refrigerant pipeline assembly, and the stop valve is used to prevent the refrigerant in the refrigerant pipeline assembly of the air-conditioning outdoor unit from leaking; when the air-conditioning outdoor unit is being transported or the air-conditioning outdoor unit is in a non-working state, closing the stop valve can prevent the refrigerant in the refrigerant pipeline assembly from overflowing; when the air-conditioning outdoor unit is installed in a HVAC equipment or an air-conditioning system, opening the stop valve, the refrigerant pipeline assembly and other equipment are connected to form a refrigerant circulation loop, so that the HVAC equipment or the air-conditioning system can realize cooling or heating through heat exchange of the refrigerant medium.

[0048] In order to keep the refrigerant pipeline assembly of the air-conditioning outdoor unit in a clean state and protect the equipment connected to it from being corroded by impurities, the existing air-conditioning outdoor unit usually sets the stop valve at the end of the air-conditioning outdoor unit, that is, the inlet and outlet positions of the refrigerant of the air-conditioning outdoor unit. The adverse consequence is that when the air-conditioning outdoor unit is installed in the HVAC equipment or air-conditioning system, the outlet and inlet positions of the refrigerant of the air-conditioning outdoor unit usually need to be connected to the interface of other equipment such as the indoor unit by welding. The high temperature generated by welding will affect the stop valve. In severe cases, the valve body of the stop valve will be damaged, so that the stop valve fails and cannot connect or disconnect the refrigerant pipeline of the air-conditioning outdoor unit.

[0049] In view of the above problems, the air conditioner outdoor unit of the present invention reasonably arranges the positional relationship of various components in the air conditioner outdoor unit, and sets filters at the inlet and outlet of the refrigerant of the air conditioner outdoor unit. The connection relationship of the filters is as follows:

[0050] One inlet and outlet of the filter is connected to the stop valve through a refrigerant pipeline, and the other inlet and outlet of the filter is connected to other equipment outside the air-conditioning outdoor unit through the refrigerant pipeline. The refrigerant pipeline connected to the other inlet and outlet of the filter extends in a direction away from the filter and the stop valve. Therefore, when the pipeline interface connected to the other inlet and outlet of the filter is connected to other equipment outside the air-conditioning outdoor unit by welding, the high temperature generated during welding can be kept away from the stop valve, preventing the high temperature from damaging the stop valve, protecting the safety of the stop valve, and also improving the environmental adaptability of the air-conditioning outdoor unit.

[0051] The air-conditioning outdoor unit of the utility model sequentially connects a valve port of a multi-way valve, a stop valve and a filter through a plurality of refrigerant pipelines. In the formed refrigerant flow path, the filter is located upstream or downstream of the refrigerant flow path and is far away from the multi-way valve and the stop valve. The air-conditioning outdoor unit of the utility model solves the adverse effects of high temperature generated by welding on the stop valve.

[0052] No filter is arranged between the multi-way valve and the stop valve, and there is more space between the multi-way valve and the stop valve to arrange the refrigerant medium pipeline, thereby reducing the problem of extending the refrigerant pipeline due to interference between different refrigerant pipelines and between different refrigerant pipelines and filters.

[0053] Therefore, the air-conditioning outdoor unit of the utility model can reduce the unreasonable extension of different refrigerant pipelines, reduce the effective length of the refrigerant pipelines, and reduce the cost by reasonably arranging the multi-way valve, stop valve and filter inside it. On the other hand, the structure inside the air-conditioning outdoor unit is simpler and the layout is more reasonable, which is convenient for later repair and maintenance. Furthermore, the stop valve of the air-conditioning outdoor unit is effectively protected, reducing the adverse effects of high welding temperature, and at the same time improving the environmental adaptability of the air-conditioning outdoor unit.

[0054] Different implementation modes of the present invention are explained in detail below in conjunction with the accompanying drawings. It should be noted that the accompanying drawings and embodiments are only used to explain the present invention and cannot be understood as limiting the present invention.

[0055] Figure 3 1 is a schematic diagram of the connection between a valve port of a multi-way valve of an air conditioner outdoor unit of an embodiment of the present utility model, a first stop valve 131 and a filter 140, wherein the first stop valve 131 is arranged on a mounting plate 160, such as Figure 3 As shown, the multi-way valve 120 of the air-conditioning outdoor unit 100 of the utility model has multiple valve ports, including a first valve port 121121. The air-conditioning outdoor unit 100 also includes a first stop valve 131 and a first filter 141, and also includes a first pipeline 111, a second pipeline 112, and a third pipeline 113.

[0056] The first valve port 121 of the multi-way valve 120 is connected to one end of the third pipeline 113, the other end of the third pipeline 113 is connected to an inlet and outlet of the first stop valve 131, the other inlet and outlet of the first stop valve 131 is connected to one end of the second pipeline 112, the other end of the second pipeline 112 is connected to an inlet and outlet of the first filter 141, the other inlet and outlet of the first filter 141 is connected to one end of the first pipeline 111, and the other end of the first pipeline 111 extends in a direction away from the first filter 141, the first stop valve 131 and the multi-way valve 120.

[0057] In the air-conditioning outdoor unit 100 of the present embodiment, a gaseous refrigerant passage 114 is formed through a plurality of refrigerant pipelines between the first valve port 121 of the multi-way valve 120 , the first stop valve 131 , and the first filter 141 .

[0058] In the formed gas refrigerant passage, according to the different cooling or heating requirements of the air-conditioning outdoor unit 100, the flow direction of the refrigerant can flow along the direction of the first valve port 121, the first stop valve 131 and the first filter 141; the flow direction of the refrigerant can also flow along the direction of the first filter 141, the first stop valve 131 and the first valve port 121.

[0059] Among them, the other end of the first pipeline 111 is the refrigerant interface of the air-conditioning outdoor unit 100, which is used to connect with other equipment. The refrigerant interface can be the refrigerant input port of the air-conditioning outdoor unit, and can also be the refrigerant output port of the air-conditioning outdoor unit.

[0060] In one embodiment, the air-conditioning outdoor unit 100 of the utility model is applied to a HVAC equipment or an air-conditioning system, and the HVAC equipment or the air-conditioning system is provided with at least one air-conditioning outdoor unit 100 provided by the utility model, and also includes at least one air-conditioning indoor unit, wherein the refrigerant interface of the air-conditioning indoor unit is connected to the other end of the first pipeline 111 of the air-conditioning outdoor unit 100 of the utility model, and a refrigerant circulation loop is formed between the refrigerant pipeline of the air-conditioning indoor unit and the refrigerant pipeline assembly 110 of the air-conditioning outdoor unit 100.

[0061] When the other end of the first pipeline 111 of the air-conditioning outdoor unit 100 of the utility model is connected to the refrigerant interface of the air-conditioning indoor unit by welding, since the other end of the first pipeline 111 is far away from the first filter 141, the first stop valve 131 and the multi-way valve 120, the high temperature generated by welding between the other end of the first pipeline 111 and the refrigerant interface of the air-conditioning indoor unit will not affect the first filter 141, the first stop valve 131 and the multi-way valve 120.

[0062] like Figure 3 As shown, along the vertical direction, the distance between the first filter 141 and the first stop valve 131 is D1, and the distance between the first filter 141 and the multi-way valve 120 is D2, D1<D2, that is, the first filter 141 is not arranged between the first stop valve 131 and the multi-way valve 120, and the first filter 141 will not interfere with the refrigerant pipeline connected to the multi-way valve 120, so that there is a larger space between the first stop valve 131 and the multi-way valve 120 for arranging the refrigerant pipeline, thereby reducing the problem of excessive length of the refrigerant pipeline due to avoiding the first filter 141 and the unreasonable path of the refrigerant pipeline.

[0063] In particular, the other end of the first pipeline 111 is far away from the first stop valve 131, and the high welding temperature will not damage the first stop valve 131, thereby ensuring the safety of the first stop valve 131 and ensuring that the refrigerant in the refrigerant pipeline assembly 110 of the air-conditioning outdoor unit 100 will not leak.

[0064] The air-conditioning outdoor unit 100 in this embodiment can not only ensure that the refrigerant pipeline is arranged in a reasonable path between the first stop valve 131 and the multi-way valve 120, but also reduce the influence of the high temperature generated when the other end of the first pipeline 111 is welded with other equipment on the first filter 141, the first stop valve 131 and the multi-way valve 120.

[0065] Figure 4 FIG. 1 is a schematic diagram of the connection between another valve port of the multi-way valve of the air conditioner outdoor unit of an embodiment of the present utility model, the second stop valve 132 and the filter 140, wherein the second stop valve 132 is arranged on the mounting plate 160, as shown in FIG. Figure 4 As shown, the air conditioner outdoor unit 100 of this embodiment includes a second stop valve 132 and a second filter 142, a fourth pipeline 115, a fifth pipeline 116 and a sixth pipeline 117, and a multi-way valve 120. The multi-way valve 120 has a second valve port 122. The connection relationship between the second stop valve 132, the second filter 142 and the second valve port 122 of the multi-way valve 120 is as follows:

[0066] The second valve port 122 of the multi-way valve 120 is connected to one end of the sixth pipeline 117, the other end of the sixth pipeline 117 is connected to an inlet and outlet of the second stop valve 132, the other inlet and outlet of the second stop valve 132 is connected to one end of the fifth pipeline 116, the other end of the fifth pipeline 116 is connected to an inlet and outlet of the second filter 142, the other inlet and outlet of the second filter 142 is connected to one end of the fourth pipeline 115, and the other end of the fourth pipeline 115 extends in a direction away from the second filter 142, the second stop valve 132 and the multi-way valve 120.

[0067] In the air-conditioning outdoor unit 100 of the present embodiment, a liquid refrigerant passage 118 is formed through a plurality of refrigerant pipelines between the second valve port 122 of the multi-way valve 120 , the second stop valve 132 , and the second filter 142 .

[0068] In the formed liquid refrigerant passage, according to the different cooling or heating requirements of the air-conditioning outdoor unit 100, the flow direction of the refrigerant can flow along the direction of the second valve port 122, the second stop valve 132 and the second filter 142; the flow direction of the refrigerant can also flow along the direction of the second filter 142, the second stop valve 132 and the second valve port 122.

[0069] The other end of the fourth pipeline 115 is a refrigerant interface of the air-conditioning outdoor unit 100, which is used to connect with other devices.

[0070] In the air-conditioning outdoor unit 100 of the present embodiment, the second stop valve 132 is far away from the other end of the fourth pipeline 115. When the other end of the fourth pipeline 115 is connected to other equipment by welding, the high temperature generated during the welding process will not affect the second stop valve 132, thereby ensuring the safety of the second stop valve 132 and avoiding leakage of the refrigerant medium in the refrigerant pipeline assembly 110 of the air-conditioning outdoor unit 100 due to damage to the second stop valve 132.

[0071] In one embodiment, the air-conditioning outdoor unit 100 of the utility model is suitable for a HVAC device or an air-conditioning system, and the HVAC device or the HVAC device also includes an air-conditioning indoor unit, and the refrigerant interface of the air-conditioning indoor unit is connected to the other end of the fourth pipeline 115, and a refrigerant circulation loop is formed between the refrigerant pipeline of the air-conditioning indoor unit and the refrigerant pipeline assembly 110 of the air-conditioning outdoor unit 100.

[0072] When installing the HVAC equipment or air-conditioning system, the refrigerant interface of the air-conditioning indoor unit is connected to the other end of the fourth pipeline 115 by welding. The high temperature of welding will not cause damage to the second stop valve 132, thereby ensuring the safety of the second stop valve 132, avoiding the leakage of the refrigerant medium in the liquid refrigerant passage 118 of the air-conditioning outdoor unit 100, and avoiding the leakage of the refrigerant medium in the refrigerant circulation loop of the HVAC equipment or air-conditioning system.

[0073] In the air-conditioning outdoor unit 100 of the present embodiment, since the second filter 142 is not arranged between the second stop valve 132 and the multi-way valve 120, there is a larger space between the second stop valve 132 and the multi-way valve 120 for arranging the refrigerant pipeline. The refrigerant pipeline can be arranged in a more reasonable path without avoiding the second filter 142, thereby reducing unnecessary extension of the refrigerant pipeline.

[0074] In the above two embodiments, the multi-way valve 120 in the air-conditioning outdoor unit 100 can be set as a four-way valve.

[0075] The four-way valve can meet the requirements of connecting and disconnecting the gaseous refrigerant passage 114 and the liquid refrigerant passage 118 in the HVAC equipment or air-conditioning system.

[0076] like Figure 3 and Figure 4 As shown, the air-conditioning outdoor unit 100 also includes a mounting plate 160, which is used to fix the first stop valve 131 or the second stop valve 132. In the air-conditioning outdoor unit 100 of this embodiment, a mounting plate 160 is separately provided to fix the stop valve 130 of the air-conditioning outdoor unit 100, thereby reducing the influence of the vibration of the compressor and the fan in the air-conditioning outdoor unit 100 during operation on the stop valve 130.

[0077] In particular, when multiple stop valves 130 are installed in the air-conditioning outdoor unit 100, the multiple stop valves 130 are fixed on the mounting plate 160, which can reduce the impact of vibration on the stop valves 130 and the refrigerant pipeline assembly 110, and the multiple stop valves 130 can also be centrally fixed to facilitate subsequent repair and maintenance.

[0078] The mounting plate 160 is disposed in the housing 150 and can be connected to the inner wall of the housing 150 to fix the mounting plate 160 .

[0079] Figure 1 This is a schematic structural diagram of an air-conditioning outdoor unit according to an embodiment of the utility model. Figure 2 3D diagram of an air conditioner outdoor unit according to an embodiment of the present invention, Figure 1 and Figure 2 As shown, the air-conditioning outdoor unit 100 of this embodiment includes a shell 150, in which a refrigerant pipeline assembly 110, at least one stop valve 130 and at least one filter 140 are arranged, and a multi-way valve 120 is arranged on the refrigerant pipeline assembly 110. The multi-way valve 120 can be a four-way valve. The valve port of the multi-way valve 120, the stop valve 130 and the filter 140 are connected in sequence through the refrigerant pipeline, and the filter 140 is far away from the multi-way valve 120 and the stop valve 130.

[0080] like Figure 1 and Figure 2 As shown, two air outlets 153 are arranged on the side wall of the shell 150 of the air-conditioning outdoor unit 100, and the two air outlets 153 are arranged at intervals. In the partial accommodation space in the shell 150 adjacent to the two air outlets 153, a refrigerant pipeline assembly 110, a stop valve 130 and a filter 140 are arranged.

[0081] like Figure 1 As shown, a first installation port 151 is further provided on the housing 150 , and the first installation port 151 is used for installing and removing the multi-way valve 120 and the stop valve 130 .

[0082] The housing 150 is provided with a second installation opening 152 , and the second installation opening 152 is used for installing and removing the filter 140 .

[0083] Among them, the second installation port 152 and the first installation port 151 can be set at intervals, and the second installation port 152 and the first installation port 151 can also be combined to form one installation port for installing and disassembling the multi-way valve 120, the stop valve 130, the filter 140 and the refrigerant pipeline assembly 110.

[0084] Combination Figure 1 and Figure 2It can also be seen that the filter 140 is arranged below the stop valve 130 and the multi-way valve 120, so that the filter 140 can be away from the stop valve 130 and the multi-way valve 120, and the refrigerant pipeline connected to the filter 140 can extend in a direction away from the multi-way valve 120 and the stop valve 130. When the end of the refrigerant pipeline away from the filter 140 is welded to other equipment, the influence of the high welding temperature on the stop valve 130 can be reduced.

[0085] In one embodiment of the present invention, a refrigerant passage is formed in the refrigerant pipeline assembly 110 , and the filter 140 is disposed at one end of the refrigerant passage.

[0086] like Figure 1 As shown, a pipe inlet and outlet 154 is also provided in the shell 150 of the air-conditioning outdoor unit 100. When the air-conditioning outdoor unit 100 of the utility model is applied to a HVAC equipment or an air-conditioning system, the refrigerant interface of the indoor unit of the HVAC equipment or the air-conditioning system can be set in the shell 150 through the pipe inlet and outlet 154, and connected to an inlet and outlet of the filter 140 of the air-conditioning outdoor unit 100.
