DETAILED DESCRIPTION
[0023] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.
[0024] In the present disclosure, the orientation words such as "inner" and "outer" refer to the contour of the parts themselves, unless otherwise stated. In addition, it should be noted that the terms such as "first", "second" and the like are used to distinguish one element from another, and do not have sequential and important meanings. In addition, in the description with reference to the drawings, the same reference signs in different drawings represent the same elements.
[0025] In the related art, an air conditioner needs to be tested by an air conditioner test device before leaving the factory, and the air conditioner test device includes a laboratory and a large air conditioning system. The laboratory can include a high-temperature outdoor unit room and a low-temperature indoor unit room, and the temperature in the outdoor unit room and the indoor unit room is adjusted by the large air conditioning system to realize variable temperature operation test. However, when heat exchange is performed through the temperature balance air outlet in the high-temperature outdoor unit room, condensation phenomenon is easily generated outside the outdoor unit room, which affects the working environment outside the outdoor unit room. For example, the air conditioner test device is usually arranged in a workshop or an experimental building. When the air conditioner is tested, the high-temperature outdoor unit room will gradually increase in temperature until the preset temperature as the air conditioner outdoor unit works. The preset temperature is usually higher than the temperature in the workshop or the experimental building. The outdoor unit room is a closed space, and part of the hot air in the outdoor unit room can be intermittently discharged through the exhaust structure on the outdoor unit room. At the same time, the air inlet structure can be opened to replace the outside air into the outdoor unit room, so as to control the air temperature in the outdoor unit room within the preset range. When the hot air in the high-temperature outdoor unit room in the air conditioner test device exchanges heat with the external environment, condensation phenomenon is easily generated outside the outdoor unit room. In particular, the laboratory in the air conditioner test device is usually located inside the building, thereby forming a "room-in-room" structure. The air outlet of the laboratory usually faces the window of the building. When the outside air temperature is low, especially in winter, the hot air meets the cold glass and easily generates condensation on the glass, thereby affecting the working environment outside the laboratory in the air conditioner test device.
[0026] To solve the above technical problems, as shown in Figures 1-4 The present disclosure provides an air conditioner test device, which comprises an outdoor unit room 1, a heat exchange channel 5 and a condensation removal structure 6. The outdoor unit room 1 is provided with an outdoor unit 3 for heating the outdoor unit room 1. The indoor unit room 2 is provided with an indoor unit 4 for cooling the indoor unit room 2 and corresponding to the outdoor unit 3. The heat exchange channel 5 is arranged on the outdoor unit room 1 and used to communicate the outdoor unit room 1 with the external environment. The condensation removal structure 6 is arranged on the heat exchange channel 5.
[0027] By the above technical scheme, by setting the heat exchange channel 5 on the outdoor unit room 1, and setting the condensation removal structure 6 on the heat exchange channel 5, when the high-temperature air in the outdoor unit room 1 is discharged and exchanges heat with the normal-temperature air outside, the condensation phenomenon caused by the heat exchange of cold and hot air can be reduced by the setting of the condensation removal structure 6, thereby improving the working environment outside the outdoor unit room 1. Especially, when the air conditioning experimental equipment is arranged in the experimental building, the laboratory in the air conditioning experimental equipment is usually located inside the building, thereby forming a "room-in-room" structure, and the air outlet of the laboratory usually faces the window of the building. In addition to the air conditioning experimental equipment, other working areas are also arranged inside the building. When the air temperature outside is low, especially in winter, hot air is easy to produce condensation on the glass. The condensation removal structure 6 arranged on the heat exchange channel 5 can reduce the condensation on the cold glass, thereby improving the working environment outside the outdoor unit room 1.
[0028] It should be noted that, in order to control the temperature and pressure in the outdoor unit room 1 to be within a preset range, in some implementable manners, the outdoor unit room 1 can be provided with an air inlet structure (not shown in the figure) and an air outlet structure (not shown in the figure). The air inlet structure and the air outlet structure can each include a check valve and a fan. By the setting of the check valve, when the air inlet structure and the air outlet structure are not working, the hot air in the outdoor unit room 1 will not leak. The fan of the air inlet structure can be started to guide the air outside into the outdoor unit room 1. The fan of the air outlet structure can be started to guide the hot air in the outdoor unit room 1 to be discharged, thereby adjusting the air temperature in the outdoor unit room 1 and controlling the air temperature and pressure in the outdoor unit room 1 to be within a preset range. When the temperature in the outdoor unit room 1 rises to a preset temperature, the heating outdoor unit 3 still continuously generates hot air. At this time, part of the hot air in the outdoor unit room 1 can be intermittently discharged through the air outlet structure, and at the same time, the air outside can be replaced into the outdoor unit room 1 through the air inlet structure. In this way, the air temperature in the outdoor unit room 1 is controlled to be within a preset range. When the hot air in the high-temperature outdoor unit room 1 in the air conditioning experimental equipment exchanges heat with the air outside, the condensation phenomenon is reduced by the condensation removal structure 6 arranged on the heat exchange channel 5, thereby improving the working environment outside the outdoor unit room 1.
[0029] It should be noted that, in the present disclosure, the structure of the condensation removal structure 6 arranged on the heat exchange channel 5 at the air outlet structure will be exemplarily described.
[0030] It can be understood that the heat exchange channel 5 described above can be a galvanized steel plate or a stainless steel plate. The cross-sectional shape and length of the heat exchange channel 5 can be set according to the size of the specific outdoor unit room 1, and the present disclosure does not make specific limitations. The heat exchange channel 5 can have two and be communicated with the air inlet structure and the air outlet structure of the outdoor unit room 1 respectively.
[0031] In some feasible implementations, to facilitate the removal of condensation during heat exchange in the heat exchange channel 5, the decondensation structure 6 can be located on the side of the heat exchange channel 5 closer to the external environment. Thus, as hot air flows through the heat exchange channel 5, condensation (condensate) is more likely to form in the portion of the heat exchange channel 5 closer to the external environment. By installing the decondensation structure 6 at this location, the condensate can be easily collected and discharged from the heat exchange channel 5, reducing direct contact between hot air and the cold glass inside the building, which would otherwise lead to condensation on the cold glass.
[0032] like Figure 1 and Figure 2 As shown, in some feasible embodiments, the decondensation structure 6 may include a condensation pipe 61 having a first opening 62 and a second opening 63. A water collection trough 64 for collecting condensate is formed at the bottom of the condensation pipe 61. The first opening 62 is for communication with the outdoor unit compartment 1, and the second opening 63 is for communication with the external environment. Thus, when hot air needs to be discharged, the hot air in the outdoor unit compartment 1 enters the condensation pipe 61 through the first opening 62 and is guided by the condensation pipe 61 to the second opening 63 for discharge. As the hot air gradually approaches the second opening 63, heat exchange begins between the hot air and the outside cold air. At this time, condensate forms on the inner wall of the condensation pipe 61. The condensate flows along the inner wall of the condensation pipe 61 and collects in the water collection trough 64 at the bottom of the condensation pipe 61, thereby reducing the direct discharge of hot air through the condensation pipe 61 to the outside of the outdoor unit compartment 1, which would otherwise exchange heat with the outside cold air and cause condensation (condensate) to form on the cold glass outside the outdoor unit compartment 1, thus improving the working environment outside the outdoor unit compartment 1.
[0033] In some feasible embodiments, to facilitate the formation of condensate on the inner wall of the condensate pipe 61 near the second opening 63, which collects in the water collection tank 64, the second opening 63 is positioned vertically above the first opening 62. For example... Figure 2 As shown, the vertical direction refers to the up-and-down direction of the paper, and the horizontal direction refers to the left-and-right direction of the paper. Figure 2 It can be seen that the condenser pipe 61 can be arc-shaped, wherein the first opening 62 can be arranged horizontally and connected to the outdoor unit room 1, the pipe body of the condenser pipe 61 is generally curved upward, the second opening 63 can be opened vertically and is located above the first opening 62 in the vertical direction, and the water collection tank 64 is set at the lowest point of the condenser pipe 61. In this way, the hot air can be blocked by the arc-shaped pipe body, and the condensate formed on the inner side wall of the condenser pipe 61 can be collected along the inner side wall of the pipe body to the water collection tank 64. Thus, the decondensation structure 6 set on the heat exchange channel 5 can reduce the condensation generated outside the outdoor unit room 1 when the hot air exchanges heat with the external environment air, and improve the working environment outside the outdoor unit room 1.
[0034] It can be understood that the above-mentioned arc-shaped structure of the pipe body of the condensation pipeline 61 is illustrative, and in other embodiments, the condensation pipeline 61 can also be configured in a serpentine shape. The serpentine-shaped condensation pipeline 61 can also play a role in blocking the flow, thereby facilitating the formation of condensed water in the part of the condensation pipeline 61 close to the second opening 63. The low points of the multiple turns of the serpentine-shaped condensation pipeline 61 close to the second opening 63 can be provided with water collecting grooves 64, thereby facilitating the collection of condensed water into the corresponding water collecting grooves 64. In this way, the dehumidification structure 6 provided on the heat exchange channel 5 can reduce the condensation generated outside the outdoor unit room 1 when the hot air exchanges heat with the air in the external environment, thereby improving the working environment outside the outdoor unit room 1.
[0035] Of course, the second opening 63 is located above the first opening 62 in the vertical direction is illustrative, in other embodiments, the relative position between the first opening 62 and the second opening 63 can be selected according to the specific shape of the condensation pipeline 61, for example, the vertical position of the first opening 62 can be located above the second opening 63, the condensation pipeline 61 can be U-shaped, and the water collecting groove 64 is provided at the lowest point of the condensation pipeline 61. In this way, the condensed water formed on the inner wall of the part of the condensation pipeline 61 close to the second opening 63 can be collected into the corresponding water collecting groove 64. In this way, the dehumidification structure 6 provided on the heat exchange channel 5 can reduce the condensation generated outside the outdoor unit room 1 when the hot air exchanges heat with the air in the external environment, thereby improving the working environment outside the outdoor unit room 1.
[0036] In some embodiments, in order to delay the overflow of the condensed water in the water collecting groove 64 into the outdoor unit room 1, the condensation pipeline 61 between the first opening 62 and the water collecting groove 64 is configured to be inclined downward toward the water collecting groove 64. In this way, when the condensed water in the water collecting groove 64 does not drain in time to form a collection, the condensation pipeline 61 between the first opening 62 and the water collecting groove 64 is inclined downward toward the water collecting groove 64, thereby forming a buffer area, thereby delaying the overflow of the condensed water in the water collecting groove 64 directly into the outdoor unit room 1.
[0037] Of course, in some embodiments, in order to delay the overflow of the condensed water in the water collecting groove 64, the condensation pipeline 61 between the second opening 63 and the water collecting groove 64 is configured to be inclined upward away from the water collecting groove 64. In this way, a buffer area is formed in the direction toward the second opening 63, thereby delaying the overflow of the condensed water collected in the water collecting groove 64.
[0038] In some embodiments, to facilitate the drainage of the condensed water in the water pan 64, the air conditioning experimental device further comprises a drain pipe 65 arranged at the lowest point of the water pan 64. Thus, the condensed water in the water pan 64 can be drained in time through the arrangement of the drain pipe 65, avoiding the accumulation of the condensed water in the water pan 64 from flowing back into the outdoor unit 1. Of course, an electromagnetic valve is arranged on the drain pipe 65, and a liquid level sensor is arranged in the water pan 64. When the liquid level sensor reaches a preset high level, the electromagnetic valve is controlled to open to drain the condensed water. When the liquid level sensor reaches a preset low level, the electromagnetic valve is controlled to close. It can be understood that the electromagnetic valve and the liquid level sensor described above are both conventional devices, and the specific structure will not be described here.
[0039] As shown in FIG. 6, to facilitate the drainage of the condensed water in the water pan 64, in some embodiments, the water pan 64 comprises a downwardly inclined bottom 66, and the drain pipe 65 is arranged at the lowest point of the bottom 66. In this way, through the inclined arrangement of the bottom 66, the condensed water collected in the water pan 64 will gather at the lowest point of the bottom 66 and be drained by the drain pipe 65. Figure 3 As shown in FIG. 7, to prolong the flow time of the hot air in the condensing pipeline 61, in some embodiments, the air conditioning experimental device further comprises a flow resistance structure arranged on the inner side wall of the condensing pipeline 61 between the water pan 64 and the second opening 63. In this way, through the arrangement of the flow resistance structure, the hot air can be hindered to some extent, and the flow time of the hot air in the condensing pipeline 61 is prolonged, so that the inner side wall of the part of the condensing pipeline 61 close to the second opening 63 has enough time to form condensed water and collect in the water pan 64 for drainage, thereby improving the working environment outside the outdoor unit 1.
[0040] Figure 4 In some embodiments, the flow resistance structure can comprise a plurality of flow resistance plates 67 arranged alternately and spaced apart on the inner side wall of the condensing pipeline 61 between the water pan 64 and the second opening 63. As shown in FIG. 8, the flow resistance plates 67 are arranged alternately and spaced apart on the inner side wall of the condensing pipeline 61 between the water pan 64 and the second opening 63.
[0041] In some embodiments, the flow resistance structure can comprise a plurality of flow resistance plates 67 arranged alternately and spaced apart on the inner side wall of the condensing pipeline 61 between the water pan 64 and the second opening 63. As shown in FIG. 8, the flow resistance plates 67 are arranged alternately and spaced apart on the inner side wall of the condensing pipeline 61 between the water pan 64 and the second opening 63. Figure 4 As shown, the flow blocking structure can include three flow blocking plates 67, the outer ends of the flow blocking plates 67 are fixedly arranged on the inner side wall of the condensing duct 61, and the inner ends of the flow blocking plates 67 extend towards the center line of the condensing duct 61. The inner side wall of the condensing duct 61 on the same side of the water collecting groove 64 is the first inner side wall, and the inner side wall of the condensing duct 61 on the opposite side of the water collecting groove 64 is the second inner side wall. Among the three flow blocking plates 67, the outer end of the flow blocking plate 67 located in the middle position is fixed on the first inner side wall, and the outer ends of the remaining two flow blocking plates 67 are fixed on the second inner side wall. The inner ends of the adjacent two flow blocking plates 67 at least partially overlap in the cross section of the condensing duct 61, so that the flow blocking structure formed by the three flow blocking plates 67 can prolong the flow time of the hot air in the condensing duct 61, so that the inner side wall of the part of the condensing duct 61 close to the second opening 63 has enough time to form condensate and collect into the water collecting groove 64 for discharge.
