Detailed Implementation

[0033] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0034] In this disclosure, the X-direction is defined for the experimental equipment used in air conditioning, where X-direction refers to the height direction of the indoor unit compartment and the outdoor unit compartment in normal operating conditions. Unless otherwise stated, directional terms such as "inner" and "outer" refer to the inner and outer contours relative to the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element.

[0035] like Figures 1 to 10 As shown, this disclosure provides an air conditioning experimental device, including an indoor unit compartment 10 and an outdoor unit compartment 20. The indoor unit compartment 10 is equipped with an indoor air conditioning unit 30, and the outdoor unit compartment 20 is equipped with an outdoor air conditioning unit 40 that cooperates with the indoor air conditioning unit 30. The air conditioning experimental device also includes an air intake structure 50 and an air pressure balancing structure 70. The air intake structure 50 connects the indoor unit compartment 10 and the outdoor unit compartment 20, and can be used to allow air to flow from the indoor unit compartment 10 to the outdoor unit compartment 20, or vice versa. The air pressure balancing structure 70 includes an indoor unit chamber balancing port 71 and an outdoor unit chamber balancing port 72. The indoor unit chamber balancing port 71 is used to allow air to enter or exit the indoor unit chamber 10 to balance the air pressure in the indoor unit chamber 10 so that the air pressure in the indoor unit chamber 10 can be maintained at a preset air pressure. The outdoor unit chamber balancing port 72 is used to allow air to enter or exit the outdoor unit chamber 20 to balance the air pressure in the outdoor unit chamber 20 so that the air pressure in the outdoor unit chamber 20 can be maintained at a preset air pressure, which facilitates the exchange of air between the indoor unit chamber 10 and the outdoor unit chamber 20, thereby facilitating the temperature regulation in the indoor unit chamber 10 and the outdoor unit chamber 20.

[0036] In the above embodiment, the air conditioner indoor unit 30 is arranged in the indoor chamber 10, and the air conditioner outdoor unit 40 cooperating with the air conditioner indoor unit 30 is arranged in the outdoor chamber 20, the indoor chamber 10 can be heated and the outdoor chamber 20 can be cooled, or the indoor chamber 10 can be cooled and the outdoor chamber 20 can be heated, so that the temperatures in the indoor chamber 10 and the outdoor chamber 20 are different, the air conditioner indoor unit 30 in the indoor chamber 10 can be used as a measured device, the operating condition of the air conditioner indoor unit 30 at the ambient temperature of the indoor chamber 10 can be detected, the air conditioner outdoor unit 40 in the outdoor chamber 20 can be used as a detected device, the operating condition of the air conditioner outdoor unit 40 at the ambient temperature of the outdoor chamber 20 can be detected, the air conditioner indoor unit 30 and the air conditioner outdoor unit 40 cooperate to change the ambient temperature of the indoor chamber 10 and the outdoor chamber 20, and the ambient temperature of the indoor chamber 10 can be used as a temperature condition for detecting the operation of the air conditioner indoor unit 30, and the ambient temperature of the outdoor chamber 20 can be used as a temperature condition for detecting the operation of the air conditioner indoor unit 30, without additionally arranging an air conditioning system, thereby reducing the energy consumption of the experiment.

[0037] However, when adjusting the temperature of the indoor chamber 10 and the outdoor chamber 20 by the air conditioner indoor unit 30 and the air conditioner outdoor unit 40, it is found that sometimes the temperature in the indoor chamber 10 and / or the outdoor chamber 20 deviates from the preset temperature, the indoor chamber 10 and the outdoor chamber 20 can be communicated with the air inlet structure 50 for allowing the indoor chamber 10 to introduce air into the outdoor chamber 20, or allowing the outdoor chamber 20 to introduce air into the indoor chamber 10, so that the gases in the indoor chamber 10 and the outdoor chamber 20 are exchanged, and then the heat exchange between the indoor chamber 10 and the outdoor chamber 20 is realized, so that the temperature in the indoor chamber 10 and / or the outdoor chamber 20 reaches the preset temperature. For example, when the air conditioner indoor unit 30 heats, the heat in the outdoor chamber 20 is transferred to the indoor chamber 10, so that the temperature in the indoor chamber 10 increases and the temperature in the outdoor chamber 20 decreases, sometimes the temperature of the outdoor chamber 20 is lower than the preset temperature, the air in the indoor chamber 10 can be introduced into the outdoor chamber 20 through the air inlet structure 50 to neutralize the temperature in the outdoor chamber 20, so that the temperature in the outdoor chamber 20 reaches the preset temperature.

[0038] However, when the air inlet structure 50 is used to introduce air from the indoor chamber 10 into the outdoor chamber 20, or introduce air from the outdoor chamber 20 into the indoor chamber 10, the air pressure in the indoor chamber 10 or the outdoor chamber 20 will increase, if the air pressure in the indoor chamber 10 or the outdoor chamber 20 is not adjusted, the air introduced into the indoor chamber 10 or the outdoor chamber 20 will be affected, and then the heat exchange between the indoor chamber 10 and the outdoor chamber 20 will be affected.

[0039] Further, as Figures 1 to 5As shown, the air-conditioning experimental device includes an air pressure balancing structure 70, which includes an inner chamber balancing port 71 and an outer chamber balancing port 72. The inner chamber balancing port 71 is used to make the inner chamber 10 enter or flow out air to balance the air pressure in the inner chamber 10, so that the air pressure in the inner chamber 10 can be maintained at a preset air pressure, which is conducive to the air exchange between the inner chamber 10 and the outer chamber 20 through the air inlet structure 50, and further conducive to the heat exchange between the inner chamber 10 and the outer chamber 20. The outer chamber balancing port 72 is used to make the outer chamber 20 enter or flow out air to balance the air pressure in the outer chamber 20, so that the air pressure in the outer chamber 20 can be maintained at a preset air pressure, which is conducive to the air exchange between the inner chamber 10 and the outer chamber 20 through the air inlet structure 50, and further conducive to the heat exchange between the inner chamber 10 and the outer chamber 20.

[0040] In some specific embodiments, when the air in the inner chamber 10 is introduced into the outer chamber 20 through the air inlet structure 50 for heat exchange between the inner chamber 10 and the outer chamber 20, air can be introduced into the inner chamber 10 through the inner chamber balancing port 71, and air in the outer chamber 20 can be discharged through the outer chamber balancing port 72, so that the air pressure in the inner chamber 10 and the air pressure in the outer chamber 20 are maintained at a preset air pressure, which is conducive to the air exchange between the inner chamber 10 and the outer chamber 20 through the air inlet structure 50, and further conducive to the heat exchange between the inner chamber 10 and the outer chamber 20.

[0041] In addition, when the air in the outer chamber 20 is introduced into the inner chamber 10 through the air inlet structure 50, air in the inner chamber 10 can be discharged through the inner chamber balancing port 71, and air can be introduced into the outer chamber 20 through the outer chamber balancing port 72, so that the air pressure in the inner chamber 10 and the air pressure in the outer chamber 20 are maintained at a preset air pressure, which is conducive to the air exchange between the inner chamber 10 and the outer chamber 20 through the air inlet structure 50, and further conducive to the heat exchange between the inner chamber 10 and the outer chamber 20.

[0042] In some embodiments, as shown in Figures 1 to 5 The air inlet structure 50 can be arbitrarily structured according to actual needs. For example, the air inlet structure 50 can include a first air passage 51 communicating the inner chamber 10 and the outer chamber 20, and a fan 52 arranged in the first air passage 51, which can provide power for the air flow in the first air passage 51.

[0043] In the above embodiment, air in the indoor unit compartment 10 can flow to the outdoor unit compartment 20 through the first air passage 51, or air in the outdoor unit compartment 20 can flow to the indoor unit compartment 10 through the first air passage 51, for heat exchange between the indoor unit compartment 10 and the outdoor unit compartment 20. The fan 52 installed in the first air passage 51 provides power for the airflow within the first air passage 51, enabling it to draw air from the indoor unit compartment 10 to the outdoor unit compartment 20, or to draw air from the outdoor unit compartment 20 to the indoor unit compartment 10, thereby accelerating the airflow between the indoor unit compartment 10 and the outdoor unit compartment 20.

[0044] In some embodiments, a second air passage 60 is provided between the indoor unit compartment 10 and the outdoor unit compartment 20, and the second air passage 60 can also be used for air circulation between the indoor unit compartment 10 and the outdoor unit compartment 20. The indoor unit compartment balance port 71 and the outdoor unit compartment balance port 72 can be located at opposite ends of the second air passage 60. For example... Figures 1 to 5 As shown, one end of the second air passage 60 is connected to the indoor unit 10 through the indoor unit balance port 71, and the other end of the second air passage 60 is connected to the outdoor unit 20 through the outdoor unit balance port 72. With the above configuration, the air in the indoor unit 10 can flow out into the second air passage 60 through the indoor unit balance port 71, and the air in the second air passage 60 can flow out into the outdoor unit 20 through the outdoor unit balance port 72; or the air in the outdoor unit 20 can flow out into the second air passage 60 through the outdoor unit balance port 72, and the air in the second air passage 60 can flow out into the indoor unit 10 through the indoor unit balance port 71, so that the indoor unit 10 and the outdoor unit 20 can exchange air through the second air passage 60, the indoor unit balance port 71 and the outdoor unit balance port 72.

[0045] It should be understood that, in order to facilitate air exchange between the indoor unit compartment 10 and the outdoor unit compartment 20 through the first air passage 51 and the second air passage 60, the airflow direction in the first air passage 51 and the airflow direction in the second air passage 60 are opposite. That is, when air in the indoor unit compartment 10 flows into the outdoor unit compartment 20 through the first air passage 51, air in the outdoor unit compartment 20 can flow into the indoor unit compartment 10 through the second air passage 60; when air in the outdoor unit compartment 20 flows into the indoor unit compartment 10 through the first air passage 51, air in the indoor unit compartment 10 can flow into the outdoor unit compartment 20 through the second air passage 60.

[0046] In some embodiments, when the inner chamber 10 is refrigerated and the outer chamber 20 is heated, the first air passage 51 is located above the second air passage 60, the fan 52 is used to send the air in the outer chamber 20 from the first air passage 51 into the inner chamber 10, the air in the inner chamber 10 flows into the outer chamber 20 through the second air passage 60, so that the inner chamber 10 and the outer chamber 20 can be maintained at a preset air pressure after completing air exchange, and the above-mentioned air in the inner chamber 10 flowing into the outer chamber 20 through the second air passage 60 can reduce the increase of air pressure in the inner chamber 10 caused by the air entering the inner chamber 10 through the first air passage 51, which can be more conducive to the fan 52 sending the air in the outer chamber 20 from the first air passage 51 into the inner chamber 10.

[0047] In the above-mentioned embodiments, the specific process of the air in the inner chamber 10 flowing into the outer chamber 20 through the second air passage 60 is that the air in the inner chamber 10 flows out of the inner chamber 10 through the inner chamber balance port 71 arranged at one end of the second air passage 60 and flows into the second air passage 60, and then the air in the second air passage 60 flows into the outer chamber 20 through the outer chamber balance port 72.

[0048] The specific process of the inner chamber 10 being refrigerated and the outer chamber 20 being heated is that the air conditioner indoor unit 30 is refrigerated, so that the air conditioner indoor unit 30 and the matched air conditioner outdoor unit 40 transfer the heat in the inner chamber 10 to the outer chamber 20, so that the temperature in the inner chamber 10 is reduced and the temperature in the outer chamber 20 is increased, and then the temperature in the outer chamber 20 is higher than the temperature in the inner chamber 10, the air in the outer chamber 20 can be hot air compared with the air in the inner chamber 10, and the air in the inner chamber 10 can be cold air compared with the air in the outer chamber 20. The first air passage 51 is located above the second air passage 60, the hot air in the outer chamber 20 can be sent into the inner chamber 10 through the first air passage 51 by the fan 52, the density of the cold air in the inner chamber 10 is greater than that of the hot air sent into the inner chamber 10, and the cold air in the inner chamber 10 is usually located below the hot air, the second air passage 60 is located below the first air passage 51, which is conducive to the cold air in the inner chamber 10 flowing into the outer chamber 20 through the second air passage 60, and the exchange of air between the inner chamber 10 and the outer chamber 20 can be completed more quickly, and then the heat transfer between the inner chamber 10 and the outer chamber 20 can be completed more quickly through the first air passage 51 and the second air passage 60, so that the inner chamber 10 and / or the outer chamber 20 can reach the preset temperature more quickly.

[0049] In some embodiments, when the inner machine chamber 10 is heating and the outer machine chamber 20 is cooling, the first air passage 51 is located above the second air passage 60, the air fan 52 is used to send the air in the inner machine chamber 10 from the first air passage 51 into the outer machine chamber 20, the air in the outer machine chamber 20 flows into the inner machine chamber 10 through the second air passage 60, so that the inner machine chamber 10 and the outer machine chamber 20 can be maintained at a preset air pressure after completing air exchange, and the above-mentioned air in the outer machine chamber 20 flows into the inner machine chamber 10 through the second air passage 60, which can reduce the increase of air pressure in the outer machine chamber 20 caused by the air entering the outer machine chamber 20 through the first air passage 51, and can be more conducive to the air fan 52 sending the air in the inner machine chamber 10 from the first air passage 51 into the outer machine chamber 20.

[0050] In the above-mentioned embodiments, the specific process of the air in the outer machine chamber 20 flowing into the inner machine chamber 10 through the second air passage 60 is that the air in the outer machine chamber 20 flows out of the outer machine chamber 20 through the outer machine chamber balance port 72 arranged at one end of the second air passage 60 and flows into the second air passage 60, and then the air in the second air passage 60 flows into the inner machine chamber 10 through the inner machine chamber balance port 71. The specific process of the outer machine chamber 20 cooling and the inner machine chamber 10 heating is that the air conditioner inner machine 30 heats, so that the air conditioner inner machine 30 and the air conditioner outer machine 40 matched therewith transfer the heat in the outer machine chamber 20 to the inner machine chamber 10, so that the temperature in the outer machine chamber 20 decreases and the temperature in the inner machine chamber 10 increases, and then the temperature in the inner machine chamber 10 is higher than the temperature in the outer machine chamber 20, and the air in the inner machine chamber 10 can be hot air compared with the air in the outer machine chamber 20, and the air in the outer machine chamber 20 can be cold air compared with the air in the inner machine chamber 10. The first air passage 51 is located above the second air passage 60, and the hot air in the inner machine chamber 10 can be sent into the outer machine chamber 20 through the first air passage 51 by the air fan 52. The cold air in the outer machine chamber 20 has a greater density than the hot air sent into the outer machine chamber 20, and the cold air in the outer machine chamber 20 is usually located below the hot air. The second air passage 60 is located below the first air passage 51, which is conducive to the cold air in the outer machine chamber 20 flowing into the inner machine chamber 10 through the second air passage 60, and can more quickly complete the air exchange between the inner machine chamber 10 and the outer machine chamber 20, and then the heat transfer between the inner machine chamber 10 and the outer machine chamber 20 can be more quickly completed through the first air passage 51 and the second air passage 60, so that the inner machine chamber 10 and / or the outer machine chamber 20 can more quickly reach the preset temperature.

[0051] In some embodiments, a blocking member 80 may be provided at the first air passage 51 and the second air passage 60 to open or close the first air passage 51 and / or the second air passage 60. The blocking member 80 may include a first blocking member 81 and a second blocking member 82. The first air passage 51 may be provided with a first blocking member 81, which is used to open or close the first air passage 51. By providing the first blocking member 81, when air exchange between the indoor unit compartment 10 and the outdoor unit compartment 20 is required, the first blocking member 81 can be opened; correspondingly, when air exchange between the indoor unit compartment 10 and the outdoor unit compartment 20 via the first air passage 51 needs to be stopped, the first blocking member 81 can be closed.

[0052] In addition, the second air passage 60 is provided with a second sealing member 82, which is used to open or close the second air passage 60. When it is necessary to use the second air passage 60 to exchange air between the indoor unit compartment 10 and the outdoor unit compartment 20, the second sealing member 82 can be used to open the second air passage 60. Correspondingly, when it is necessary to stop the air exchange between the indoor unit compartment 10 and the outdoor unit compartment 20 through the second air passage 60, the second sealing member 82 can be used to close the second air passage 60.

[0053] The reliability of the experimental equipment for air conditioning can be improved by providing a first sealing member 81 for opening or closing the first air passage 51 and a second sealing member 82 for opening or closing the second air passage 60.

[0054] In some implementations, such as Figure 1 , Figure 6 and Figure 7 As shown, the first air passage 51 is connected to the first stop structure 300. The first sealing member 81 includes multiple separable overlapping first sealing plates 811, all of which are rotatably connected to the first air passage 51. This increases the flow area of ​​the first air passage 51 when the multiple first sealing plates 811 simultaneously open the first air passage 51. The innermost first sealing plate 811 and the first stop structure 300 are separably overlapping. When the multiple first sealing plates 811 close the first air passage 51, they overlap together, with the innermost first sealing plate 811 overlapping the first stop structure 300, preventing the multiple first sealing plates 811 from rotating in opposite directions and opening the first air passage 51.

[0055] It should be noted that when the plurality of first blocking plates 811 are rotated to be separated from each other, the first blocking member 81 is in an open position to open the first air passage 51, and when the plurality of first blocking plates 811 are rotated to be overlapped with each other, the first blocking member 81 is in a closed position to close the first air passage 51. When the first blocking member 81 is in the closed position, the innermost first blocking plate 811 of the plurality of first blocking plates 811 is overlapped with the first stop structure 300.

[0056] It should be understood that the innermost first blocking plate 811 can be understood as the first blocking plate 811 that is last opened or last closed to the first air flow channel among the plurality of first blocking plates 811. When the first blocking plate 811 is rotated clockwise to open the first air passage 51, the opposite side refers to counterclockwise rotation, and when the first blocking plate 811 is rotated counterclockwise to open the first air passage 51, the opposite side refers to clockwise rotation.

[0057] In some embodiments, the first blocking plate 811 is rotationally connected to the first air passage 51, the rotation axis of the first blocking plate 811 extends in a horizontal direction, and the rotation axis of the first blocking plate 811 is located above the center of gravity of the first blocking plate 811. In this way, when the first blocking plate 811 opens the first air passage 51, part of the gravity of the first blocking plate 811 can be converted into a reset force to reset the first blocking plate 811, so that when the first air passage 51 needs to be closed, the gravity of the first blocking plate 811 can be used to reset the first blocking plate 811.

[0058] It should be noted that when the first blocking member 81 is installed at one end of the first air passage 51, the first blocking plate 811 can be configured to open the first air passage 51 when the fan 52 operates to reach a preset operating power to generate a preset air pushing force, and when the fan 52 stops operating or does not reach the preset operating power, the first blocking plate 811 resets by its own gravity to close the first air passage 51.

[0059] In other embodiments, the first blocking member 81 can also be reset by an elastic reset structure. The elastic reset structure can be provided between the first blocking member 81 and the first air passage 51, and the elastic reset structure can have an elastic force to drive the second blocking plate 821 to close the first air passage 51. That is, when the first blocking member 81 opens the first air passage 51, the elastic reset structure can store the above-mentioned elastic force to achieve automatic reset of the first blocking plate 811. The elastic reset structure can be configured as a torsion spring to adapt to the rotation of the first blocking plate 811. Of course, the elastic reset structure can also be configured as a tension spring.

[0060] Of course, the first blocking plate 811 opening or closing the first air passage 51 can also be achieved by other ways. For example, a driving mechanism can be arranged to drive the plurality of first blocking plates 811 of the first blocking member 81 to rotate to close or open the first air passage 51, which is not limited herein.

[0061] In some embodiments, as shown in Figure 1 、 Figure 6 and Figure 7 , the first stop structure 300 can be configured as a stop protrusion, and the innermost blocking plate of the plurality of first blocking plates 811 is lapped on the stop protrusion when the first air passage 51 is in the closed state. The present disclosure is not limited to this.

[0062] In some embodiments, as shown in Figure 1 、 Figure 8 、 Figure 9 and Figure 10 , the second air passage 60 is connected with a second stop structure 400, and the second blocking member 82 includes a plurality of separable lapped second blocking plates 821, and the plurality of second blocking plates 821 are all rotatably connected with the second air passage 60, so that when the plurality of second blocking plates 821 simultaneously open the second air passage 60, the flow area of the second air passage 60 can be increased. The innermost second blocking plate 821 and the second stop structure 400 are separably lapped, so that when the plurality of second blocking plates 821 close the second air passage 60, the plurality of second blocking plates 821 are lapped together, and the innermost second blocking plate 821 is lapped with the second stop structure 400, which can prevent the plurality of second blocking plates 821 from rotating in the opposite direction to open the second air passage 60.

[0063] It should be noted that when the plurality of second blocking plates 821 are rotated to be separated from each other, the second blocking member 82 is in an open position to open the second air passage 60, and when the plurality of second blocking plates 821 are rotated to be lapped with each other, the second blocking member 82 is in a closed position to close the second air passage 60, and when the second blocking member 82 is in the closed position, the innermost second blocking plate 821 of the plurality of second blocking plates 821 is lapped on the second stop structure 400.

[0064] It should be understood that the innermost second blocking plate 821 can be understood as the second blocking plate 821 of the plurality of second blocking plates 821 which is last opened or last closed the second air passage. When the second blocking plate 821 is rotated clockwise to open the second air passage 60, the opposite side refers to counterclockwise rotation, and when the second blocking plate 821 is rotated counterclockwise to open the second air passage 60, the opposite side refers to clockwise rotation.

[0065] In some embodiments, the second sealing plate 821 is rotationally connected to the second air passage 60, and a rotation reset structure 500 can be connected between the second sealing plate 821 and the second air passage 60, which can reset the second sealing plate 821 to close the second air passage 60, that is, when the second sealing plate 821 opens the second air passage 60, the rotation reset structure 500 can store a reset force, and when it is needed to close the second air passage 60, the rotation reset structure 500 can reset the second sealing plate 821 to close the second air passage 60 by the reset force, so that the reliable closing of the second air passage 60 by the second sealing plate 821 can be realized.

[0066] In some embodiments, as shown in Figure 9 and Figure 10 the rotation reset structure 500 can be configured as a rotation shaft, the rotation axis of the rotation shaft extends in the horizontal direction, the rotation axis of the second sealing plate 821 extends in the horizontal direction, and the rotation axis of the second sealing plate 821 is above the center of gravity of the second sealing plate 821, so that when the second sealing plate 821 opens the second air passage 60, the gravity of the second sealing plate 821 can be converted into a reset force to reset the second sealing plate 821, and thus when it is needed to close the second air passage 60, the rotation shaft can be used to reset the second sealing plate 821 by the gravity of the second sealing plate 821.

[0067] In other embodiments, the rotation reset structure 500 can also be configured as an elastic reset structure, which can have an elastic force to drive the second sealing plate 821 to close the second air passage 60, that is, when the second sealing plate 821 opens the second air passage 60, the elastic reset structure can store the above-mentioned elastic force to realize the automatic reset of the second sealing plate 821. The elastic reset structure can be configured as a torsion spring to adapt to the rotation of the second sealing plate 821. Of course, the elastic reset structure can also be configured as a tension spring.

[0068] It should be noted that when the second sealing member 82 is installed at one end of the second air passage 60, the second sealing plate 821 can be configured to open the second air passage 60 when the air pressure in the inner machine room 10 and the outer machine room 20 generates a preset pressure difference, and the second sealing plate 821 can be reset to close the second air passage 60 when the pressure difference of the air pressure in the inner machine room 10 and the outer machine room 20 is less than the preset pressure difference.

[0069] In addition, the opening or closing of the second air passage 60 by the second sealing plate 821 can also be realized by other ways. For example, a driving mechanism can be provided to drive the rotation of the plurality of second sealing plates 821 of the second sealing member 82 to close or open the second air passage 60, which is not limited here.

[0070] In some embodiments, referring toFigure 9 As shown, the second stop structure 400 can be configured as a protruding portion of the second air passage 60, and the innermost second blocking plate of the plurality of second blocking plates 821 is lapped on the protruding portion of the second air passage 60 when the second air passage 60 is in the closed state. The present disclosure does not limit this.

[0071] In some embodiments, as shown, Figures 1 to 5 As shown, one end of the first air passage 51 is provided with the first blocking piece 81, and one end of the second air passage 60 is provided with the second blocking piece 82. The opening direction of the first blocking piece 81 provided at the first air passage 51 is opposite to the opening direction of the second blocking piece 82 provided at the second air passage 60. Here, since the first air passage 51 and the second air passage 60 are used as one-way passages, and the flow directions of the two are opposite, the opening direction of the first blocking piece 81 at the first air passage 51 is opposite to the opening direction of the second blocking piece 82 of the second air passage 60. On the one hand, it can adapt to the flow of air respectively, and on the other hand, it can realize the self-locking of the first blocking piece 81 and the second blocking piece 82. For example, when the innermost first blocking plate 811 in the first blocking piece 81 is lapped with the first stop structure 300 and the plurality of first blocking plates 811 are lapped, it can avoid that each first blocking plate 811 of the first blocking piece 81 rotates to the opposite side, thereby accidentally opening the first air passage 51; when the innermost second blocking plate 821 in the second blocking piece 82 is lapped with the second stop structure 400 and the plurality of first blocking plates 811 are lapped, it can avoid that the second air passage 60 is accidentally opened.

[0072] As described above, the plurality of first blocking plates 811 of the first blocking piece 81 are pushed to the opening position by the pushing force generated when the fan 52 operates to the preset power to open the first air passage 51, and the plurality of second blocking plates 821 of the second blocking piece 82 are opened by the pressure difference between the inner machine chamber 10 and the outer machine chamber 20.

[0073] In some embodiments, as shown, Figures 1 to 5 As shown, the inner machine chamber 10 is in communication with the outside through the third air passage 90, the inner machine chamber balance port 71 is located at one end of the third air passage 90, the other end of the third air passage 90 is in communication with the outside, and the one end of the third air passage 90 is in communication with the inner machine chamber 10 through the inner machine chamber balance port 71. The inner machine chamber balance port 71 can be used to make the air in the inner machine chamber 10 flow out to the outside through the third air passage 90, or can be used to make the air of the outside flow into the inner machine chamber 10 through the third air passage 90, so that the air pressure in the inner machine chamber 10 quickly reaches the preset air pressure. Of course, when the inner machine chamber 10 exchanges air with the outside through the third air passage 90, heat exchange between the inner machine chamber 10 and the outside can also be synchronized to make the heat in the inner machine chamber 10 quickly reach the preset temperature.

[0074] It should be understood that the end of the third air passage 90 communicating with the outside can be provided with a damper to open the third air passage 90 when the inner machine chamber 10 needs to exchange air with the outside, and to close the third air passage 90 when the inner machine chamber 10 does not need to exchange air with the outside. In addition, in order to ensure the reliability and efficiency of the inner machine chamber 10 when exchanging air with the outside through the third air passage 90, an air extractor 200 can be provided in the third air passage 90 to extract air in the inner machine chamber 10 to the outside through the third air passage 90, or to deliver air from the outside to the inner machine chamber 10 through the third air passage 90.

[0075] In some embodiments, the number of third air passages 90 can be one, two or more, which is not limited here. When the number of third air passages 90 is two, one of the two third air passages 90 can be used to pass air from the outside to the inner machine chamber 10, and the other can be used to pass air from the inner machine chamber 10 to the outside.

[0076] In some embodiments, as shown in Figures 1 to 5 The outer machine chamber 20 communicates with the outside through a fourth air passage 100, and the outer machine chamber balance port 72 is located at one end of the fourth air passage 100, and the other end of the fourth air passage 100 communicates with the outside. The fourth air passage 100 communicates with the outer machine chamber 20 through the outer machine chamber balance port 72, and the outer machine chamber balance port 72 can be used to make air in the outer machine chamber 20 flow out to the outside through the fourth air passage 100, or to make air from the outside flow into the outer machine chamber 20 through the fourth air passage 100, so that the air pressure in the outer machine chamber 20 quickly reaches the preset air pressure. Of course, when the outer machine chamber 20 exchanges air with the outside through the fourth air passage 100, heat exchange between the outer machine chamber 20 and the outside can also be synchronized to make the heat in the outer machine chamber 20 quickly reach the preset temperature.

[0077] It should be understood that the end of the fourth air passage 100 communicating with the outside can be provided with a damper to open the fourth air passage 100 when the outer machine chamber 20 needs to exchange air with the outside, and to close the fourth air passage 100 when the outer machine chamber 20 does not need to exchange air with the outside. In addition, in order to ensure the reliability and efficiency of the outer machine chamber 20 when exchanging air with the outside through the fourth air passage 100, an air extractor 200 can be provided in the fourth air passage 100 to extract air in the outer machine chamber 20 to the outside through the fourth air passage 100, or to deliver air from the outside to the inner machine chamber 10 through the fourth air passage 100.

[0078] In some embodiments, the number of the fourth air passages 100 can be one, two or more, which is not limited here. When the number of the fourth air passages 100 is two, one of the two fourth air passages 100 can be used to pass the air in the outside to the outer chamber 20, and the other can be used to pass the air in the outer chamber 20 to the outside.

[0079] It should be noted that the preset air pressure or the preset temperature of the above-mentioned inner chamber 10 and the outer chamber 20 is not a fixed value. For example, the preset air pressure can be determined according to the actual situation, which can keep the air pressure between the inner chamber 10 and the outer chamber 20 balanced to ensure the reliability of the experiment. The preset temperature can also be determined according to the actual situation, which can be a value in a range, which is not limited here.

[0080] The use process of the air-conditioning experimental equipment will be introduced in the following disclosure in combination with specific embodiments. As shown in Figures 1 to 5 the air-conditioning experimental equipment can only include the inner chamber 10 and the outer chamber 20, or the air-conditioning experimental equipment can include the inner chamber 10 and the outer chamber 20 arranged on the opposite sides of the inner chamber 10.

[0081] First, the use process of the air-conditioning experimental equipment will be introduced when the air-conditioning experimental equipment only includes the inner chamber 10 and the outer chamber 20. As shown in Figure 1 and Figure 2 For example, when the inner chamber 10 is heated and the outer chamber 20 is cooled. When the temperature in the outer chamber 20 is lower than the preset temperature, the heat exchange between the inner chamber 10 and the outer chamber 20 is needed to be realized by the first air passage 51 and the second air passage 60, the fan 52 is started, under the driving of the air force of the fan 52, the first blocking piece 81 arranged in the first air passage 51 is opened, and the fan 52 passes the air in the inner chamber 10 to the outer chamber 20 through the first air passage 51. With the increase of the air in the outer chamber 20, the air pressure in the outer chamber 20 gradually increases, the pressure difference between the outer chamber 20 and the inner chamber 10 gradually increases to the preset pressure difference, the second blocking piece 82 arranged in the second air passage 60 is opened, the air in the outer chamber 20 flows into the second air passage 60 through the outer chamber balance port 72, the air in the second air passage 60 passes into the inner chamber 10 through the inner chamber balance port 71, and the air exchange between the inner chamber 10 and the outer chamber 20 is realized at the same time as the heat exchange through the first air passage 51 and the second air passage 60. When the temperature in the outer chamber 20 reaches the preset temperature, the fan 52 is closed, the first blocking piece 81 closes the first air passage 51, and when the air pressure difference between the inner chamber 10 and the outer chamber 20 is less than the preset pressure difference, the second blocking piece 82 closes the second air passage 60, the inner chamber 10 and the outer chamber 20 also reach the preset air pressure to reach the balanced state, so as to ensure the reliable operation of the air-conditioning experimental equipment.

[0082] When the inner chamber 10 is connected to the outside through the third air passage 90 and the outer chamber 20 is connected to the outside through the fourth air passage 100, when the temperature in the outer chamber 20 is lower than the preset value, when the temperature of the outside is higher than the temperature in the outer chamber 20, the air in the outside is also sent into the outer chamber 20 through the fourth air passage 100, the air in the outer chamber 20 flows into the inner chamber 10 through the second air passage 60, and the air in the inner chamber 10 flows out to the outside through the third air passage 90, so that the temperature in the outer chamber 20 is adjusted, and the balance of the air pressure in the inner chamber 10 and the outer chamber 20 is maintained, so that the inner chamber 10 and the outer chamber 20 are maintained at the preset air pressure.

[0083] As shown in Figure 2 When the inner chamber 10 is connected to the outside through the third air passage 90 and the outer chamber 20 is connected to the outside through the fourth air passage 100, when the air in the outside is needed to be sent into the inner chamber 10 through one of the two third air passages 90, the other third air passage 90 can exhaust the gas in the inner chamber 10 to the outside to balance the air pressure in the inner chamber 10, so that the air exchange between the inner chamber 10 and the outside is fast, the temperature exchange between the inner chamber 10 and the outside is fast, and when the temperature of the inner chamber 10 is adjusted, the temperature exchange between the two third air passages 90 and the outside is performed to quickly adjust the temperature in the inner chamber 10. When the air in the outside is needed to be sent into the outer chamber 20 through one of the two fourth air passages 100, the other fourth air passage 100 can exhaust the gas in the outer chamber 20 to the outside to balance the air pressure in the outer chamber 10, so that the air exchange between the outer chamber 20 and the outside is fast, the temperature exchange between the outer chamber 20 and the outside is fast, and when the temperature of the outer chamber 20 is adjusted, the temperature and gas exchange between the two fourth air passages 100 and the outside is performed to quickly adjust the temperature in the outer chamber 20.

[0084] In the air conditioning experimental device including the inner machine room 10 and the outer machine rooms 20 arranged on opposite sides of the inner machine room 10, the outer machine rooms 20 include the first outer machine room 21 and the second outer machine room 22, the first outer machine room 21, the inner machine room 10 and the second outer machine room 22 are arranged in a line. The first air channel 51 and the second air channel 60 are communicated between the first outer machine room 21 and the inner machine room 10, one end of the second air channel 60 is communicated with the inner machine room 10 through the inner machine room balance port 71, and the other end is communicated with the first outer machine room 21 through the outer machine room balance port 72. In addition, the first air channel 51 and the second air channel 60 are communicated between the second outer machine room 22 and the inner machine room 10, one end of the second air channel 60 is communicated with the inner machine room 10 through the inner machine room balance port 71, and the other end is communicated with the second outer machine room 22 through the outer machine room balance port 72. In addition, the air conditioner inner machine 30 arranged in the inner machine room 10 includes the first air conditioner inner machine 31 and the second air conditioner inner machine 32, the first outer machine room 21 is provided with the first air conditioner outer machine 41 matched with the first air conditioner inner machine 31, and the second outer machine room 22 is provided with the second air conditioner outer machine 42 matched with the second air conditioner inner machine 32. Among them, the first air conditioner inner machine 31 can be used for refrigeration of the inner machine room 10, the first air conditioner outer machine 41 can be used for heating of the first outer machine room 21, the second air conditioner inner machine 32 can be used for heating of the inner machine room 10, and the second air conditioner outer machine 42 can be used for refrigeration of the second outer machine room 22. Therefore, the temperature in the first outer machine room 21 is higher than that in the inner machine room 10, and the temperature in the inner machine room 10 is higher than that in the second outer machine room 22, which can be defined as the first outer machine room 21 as the high-temperature room, the inner machine room 10 as the normal-temperature room, and the second outer machine room 22 as the low-temperature room.

[0085] When the temperature in the inner machine room 10 is lower than the preset value and the temperature in the inner machine room 10 needs to be increased, the fan 52 in the first air channel 51 between the inner machine room 10 and the first outer machine room 21 is started to open the first blocking piece 81 arranged at one end of the first air channel 51, and the air in the first outer machine room 21 is introduced into the inner machine room 10. As the air in the inner machine room 10 increases, the pressure difference between the inner machine room 10 and the first outer machine room 21 reaches the preset value, the second blocking piece 82 arranged at the second air channel 60 between the inner machine room 10 and the first outer machine room 21 is opened, and the air in the inner machine room 10 is introduced into the first outer machine room 21 through the second air channel 60. When the temperature in the inner machine room 10 reaches the preset temperature, the first blocking piece 81 closes the first air channel 51, and the second blocking piece 82 closes the second air channel 60, and the air pressure between the first outer machine room 21 and the inner machine room 10 can be maintained at the preset air pressure to maintain the air pressure balance between the first outer machine room 21 and the inner machine room 10.

[0086] When it is necessary to lower the temperature of the inner chamber 10, the fan 52 in the first air passage 51 between the inner chamber 10 and the second outer chamber 22 is started to open the first blocking member 81 arranged at one end of the first air passage 51, and the air in the inner chamber 10 is passed into the second outer chamber 22. As the air in the second outer chamber 22 increases, the pressure difference between the inner chamber 10 and the second outer chamber 22 reaches a preset value, the second blocking member 82 arranged at the second air passage 60 between the inner chamber 10 and the second outer chamber 22 is opened, and the air in the second outer chamber 22 is passed into the inner chamber 10 through the second air passage 60. When the temperature in the inner chamber 10 reaches a preset temperature, the fan 52 is stopped, the first blocking member 81 closes the first air passage 51, and the second blocking member 82 closes the second air passage 60. The air pressure between the second outer chamber 21 and the inner chamber 10 can be maintained at a preset air pressure to maintain the air pressure balance between the second outer chamber 21 and the inner chamber 10.

[0087] In addition, as shown in Figure 3 and Figure 4 When the inner chamber 10 is communicated with the outside through the third air passage 90, and the first outer chamber 21 and the second outer chamber 22 are each communicated with the outside through the fourth air passage 100, the inner chamber 10 can exhaust air to the outside through the third air passage 90, or the inner chamber 10 passes air in the outside into the inner chamber 10 through the third air passage 90 to realize the rapid adjustment of the air pressure in the inner chamber 10. The first outer chamber 21 can pass air in the outside into the first outer chamber 21 through the fourth air passage 100, or the first outer chamber 21 exhausts air to the outside through the fourth air passage 100 to realize the rapid adjustment of the air pressure in the first outer chamber 21. The second outer chamber 22 can pass air in the outside into the second outer chamber 22 through the fourth air passage 100, or the second outer chamber 22 exhausts air to the outside through the fourth air passage 100 to realize the rapid adjustment of the air pressure in the second outer chamber 22.

[0088] As shown in Figure 5As shown, the third air channels 90 connecting the inner machine chamber 10 with the outside can be two, the fourth air channels 100 connecting the first outer machine chamber 21 with the outside can be two, and the fourth air channels 100 connecting the second outer machine chamber 22 with the outside can also be two. Among them, one of the two third air channels 90 connecting the inner machine chamber 10 with the outside can pass the air in the inner machine chamber 10 to the outside, and the other can pass the air from the outside to the inner machine chamber 10, which can quickly exchange heat between the inner machine chamber 10 and the outside while maintaining the air pressure balance in the inner machine chamber 10. One of the two fourth air channels 100 connecting the first outer machine chamber 21 with the outside can pass the air in the first outer machine chamber 21 to the outside, and the other can pass the air from the outside to the first outer machine chamber 21, which can quickly exchange heat between the first outer machine chamber 21 and the outside while maintaining the air pressure balance in the first outer machine chamber 21. One of the two fourth air channels 100 connecting the second outer machine chamber 22 with the outside can pass the air in the second outer machine chamber 22 to the outside, and the other can pass the air from the outside to the second outer machine chamber 22, which can quickly exchange heat between the second outer machine chamber 22 and the outside while maintaining the air pressure balance in the second outer machine chamber 22.

[0089] It should be noted that there are many ways of air exchange between the inner machine chamber 10, the first outer machine chamber 21 and the second outer machine chamber 22, which will not be described here.
