That is to say, the indoor unit will increase the temperature of the indoor unit chamber, and the outdoor unit will decrease the temperature of the outdoor unit chamber. Thus, the outdoor unit can cool the outdoor unit chamber to provide a low-temperature environment for itself. In this way, through the heat transfer from the outdoor unit chamber to the indoor unit chamber, the heat of the outdoor unit chamber and the indoor unit chamber itself can be used to provide a low-temperature environment for the outdoor unit to conduct low-temperature tests on the outdoor unit, thereby reducing or even avoiding the energy consumption generated by using an external air-conditioning system to cool the outdoor unit chamber.

[0036] Similarly, when the indoor unit and the outdoor unit cooperate for refrigeration, that is, the indoor unit and the outdoor unit can transfer the heat in the indoor unit room to the outdoor unit room. That is to say, the indoor unit will lower the temperature of the indoor unit room, and the outdoor unit will raise the temperature of the outdoor unit room. Thus, the outdoor unit can raise the temperature of the outdoor unit room to provide a high-temperature environment for itself. In this way, through the heat transfer from the indoor unit room to the outdoor unit room, the heat of the outdoor unit room and the indoor unit room itself can be used to provide a high-temperature environment for the outdoor unit to conduct a high-temperature test on the outdoor unit, thereby reducing or even avoiding the energy consumption generated by using an external air-conditioning system to raise the temperature of the outdoor unit room.

[0037] In addition, by using the heat transfer channel, mutual heat transfer between the indoor unit room and the outdoor unit room, or heat transfer from one of them to the other can be realized. Since the heat transfer channel is provided with a heat transfer control structure, the heat transfer control structure can control the appropriate amount of heat transferred from the indoor unit room to the outdoor unit room, or control the appropriate amount of heat transferred from the outdoor unit room to the indoor unit room. It can balance the temperature of any one of the indoor unit room and the outdoor unit room, which is beneficial to avoiding the temperature of the indoor unit room being too high or too low, or avoiding the temperature of the outdoor unit room being too low or too high. That is, the heat transfer control structure provided in the heat transfer channel can make the indoor unit room and / or the outdoor unit room be in the corresponding experimental temperature range. Thus, it is beneficial to conduct a long-term test on the outdoor unit and improve the reliability of the experimental equipment for air conditioners.

Detailed implementation manners

[0050] The following details the specific implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for the purpose of illustrating and explaining the present disclosure, and are not intended to limit the present disclosure.

[0051] In the present disclosure, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" are defined based on the gravity direction of the experimental equipment for air conditioners, where "upper" corresponds to "top" and "lower" corresponds to "bottom". "Inner and outer" refer to the inside and outside of the self - contour of each component. The terms "first, second" are used to distinguish one element from another, without sequence and importance. In addition, when the following description refers to the accompanying drawings, the same reference numerals in different drawings represent the same or similar elements, and the present disclosure will not repeat them.

[0052] According to some embodiments of the present disclosure, an experimental equipment for air conditioners is provided. Referring to Figure 1 and Figure 2 as shown, the air conditioner experimental equipment includes an indoor unit chamber 11 and an outdoor unit chamber 12. An indoor unit 10 is arranged in the indoor unit chamber 11, and an outdoor unit 20 is arranged in the outdoor unit chamber 12. The indoor unit 10 and the outdoor unit 20 cooperate to heat the indoor unit chamber 11 or cooperate to cool the indoor unit chamber 11.

[0053] Among them, a heat transfer channel 2 can be provided between the indoor unit chamber 11 and the outdoor unit chamber 12. The heat transfer channel 2 is used for mutual heat transfer between the two or heat transfer from one of them to the other. The heat transfer channel is provided with a heat transfer control structure to make the indoor unit chamber and / or the outdoor unit chamber in the corresponding experimental temperature range.

[0054] Through the above technical solution, in the experimental equipment for air conditioners provided by the present disclosure, when the indoor unit 10 and the outdoor unit 20 cooperate for heating, that is, the indoor unit 10 and the outdoor unit 20 can transfer the heat in the outdoor unit chamber 12 to the indoor unit chamber 11. That is to say, the indoor unit 10 will increase the temperature of the indoor unit chamber 11, and the outdoor unit 20 will decrease the temperature of the outdoor unit chamber 12. Thus, the outdoor unit 20 can cool the outdoor unit chamber 12 to provide a low-temperature environment for itself. In this way, through the heat transfer from the outdoor unit chamber 12 to the indoor unit chamber 11, the heat of the outdoor unit chamber 12 and the indoor unit chamber 11 itself can be used to provide a low-temperature environment for the outdoor unit 20 to conduct a low-temperature test on the outdoor unit 20, thereby reducing or even avoiding the energy consumption generated by using an external air-conditioning system to cool the outdoor unit chamber 12.

[0055] Similarly, when the indoor unit 10 and the outdoor unit 20 cooperate for refrigeration, that is, the indoor unit 10 and the outdoor unit 20 can transfer the heat in the indoor unit chamber 11 to the outdoor unit chamber 12. That is to say, the indoor unit 10 will decrease the temperature of the indoor unit chamber 11, and the outdoor unit 20 will increase the temperature of the outdoor unit chamber 12. Thus, the outdoor unit 20 can heat the outdoor unit chamber 12 to provide a high-temperature environment for itself. In this way, through the heat transfer from the indoor unit chamber 11 to the outdoor unit chamber 12, the heat of the outdoor unit chamber 12 and the indoor unit chamber 11 itself can be used to provide a high-temperature environment for the outdoor unit 20 to conduct a high-temperature test on the outdoor unit 20, thereby reducing or even avoiding the energy consumption generated by using an external air-conditioning system to heat the outdoor unit chamber 12. Here, the heat of the indoor unit chamber 11 and the outdoor unit chamber 12 themselves can be understood as at least including the internal energy stored in the air in each of them.

[0056] In addition, by using the heat transfer channel 2, mutual heat transfer between the indoor unit chamber 11 and the outdoor unit chamber 12 or heat transfer from one of them to the other can be realized. Since the heat transfer channel is provided with a heat transfer control structure, the heat transfer control structure can control an appropriate amount of heat transferred from the indoor unit chamber 11 to the outdoor unit chamber 12 or control an appropriate amount of heat transferred from the outdoor unit chamber 12 to the indoor unit chamber 11. It can balance the temperature of either the indoor unit chamber 11 or the outdoor unit chamber 12, which is beneficial to avoiding the temperature of the indoor unit chamber 11 being too high or too low, or avoiding the temperature of the outdoor unit chamber 12 being too low or too high. That is, the heat transfer control structure provided in the heat transfer channel can make the indoor unit chamber and / or the outdoor unit chamber in the corresponding experimental temperature range. Thus, it is beneficial to conduct a long-term test on the outdoor unit 20 and improve the reliability of the experimental equipment for air conditioners.

[0057] It should be noted that the heat transfer channel 2 is used for heat transfer between one of the indoor unit chamber 11 and the outdoor unit chamber 12 and the other. It can be understood that: the indoor unit chamber 11 transfers heat to the outdoor unit chamber 12 through the heat transfer channel 2, or the outdoor unit chamber 12 transfers heat to the indoor unit chamber 11 through the heat transfer channel 2.

[0058] In some embodiments of the present disclosure, the indoor unit 10 and the outdoor unit 20 cooperate as the device to be tested. That is, the indoor unit 10 and the outdoor unit 20 as a whole are tested as the device to be tested. The air-conditioning experimental equipment can perform low-temperature tests on the device to be tested, or perform high-temperature tests on the device to be tested. Among them, the air-conditioning experimental equipment can test the reliability of the device to be tested during low-temperature and long-term operation, shorten the factory test time of the device to be tested, or can test the reliability of the device to be tested during high-temperature and long-term operation, shorten the factory test time of the device to be tested.

[0059] Next, the structure of the heat transfer channel 2 will be elaborated in detail to explain how the heat transfer control structure controls the indoor unit chamber and / or the outdoor unit chamber to be within the corresponding experimental temperature range.

[0060] In some embodiments of the present disclosure, referring to Figure 1 and Figure 2 as shown, the heat transfer channel 2 may include an air flow channel 21, and the air flow channel 21 is used to connect the indoor unit chamber 11 and the outdoor unit chamber 12. In this way, the air flow channel 21 can realize the mutual flow of air between the indoor unit chamber 11 and the outdoor unit chamber 12, or realize the air flow of one of them to the other. Thus, heat transfer can be realized through the flow of air, and the flow of air can improve the efficiency of heat transfer. Of course, in some other embodiments, the heat transfer channel 2 may also include a heat exchange medium, and the heat exchange medium may be made of a medium with good thermal conductivity. Thus, rapid heat transfer can also be realized. In addition, the heat exchange medium may have a one-way heat conduction function, or be arranged in a structure with a one-way heat conduction function to realize one-way heat conduction. The present disclosure does not limit this too much. Through the above elaboration, it can be seen that both the air flow channel 21 and the heat exchange medium are feasible embodiments of the heat transfer control structure, and both can control the indoor unit chamber and / or the outdoor unit chamber to be within the corresponding experimental temperature range.

[0061] In some embodiments of the present disclosure, referring to Figure 1 and Figure 2As shown, the air flow channel 21 may include a first air flow channel 211 and a second air flow channel 212. The first air flow channel 211 is used to allow the air in the indoor unit chamber 11 to flow into the outdoor unit chamber 12. In this way, when the indoor unit 10 cooperates with the outdoor unit 20 for refrigeration and the air in the indoor unit chamber 11 flows into the outdoor unit chamber 12, this can reduce the temperature of the outdoor unit chamber 12 and prevent the temperature of the outdoor unit chamber 12 from being too high. When the indoor unit 10 cooperates with the outdoor unit 20 for heating and the air in the indoor unit chamber 11 flows into the outdoor unit chamber 12, this can increase the temperature of the outdoor unit chamber 12 and prevent the temperature of the outdoor unit chamber 12 from being too low. The second air flow channel 212 is used to allow the air in the outdoor unit chamber 12 to flow into the indoor unit chamber 11. In this way, when the indoor unit 10 cooperates with the outdoor unit 20 for refrigeration and the air in the outdoor unit chamber 12 flows into the indoor unit chamber 11, it can increase the temperature of the indoor unit chamber 11 and prevent the temperature of the indoor unit chamber 11 from being too low. When the indoor unit 10 cooperates with the outdoor unit 20 for heating and the air in the outdoor unit chamber 12 flows into the indoor unit chamber 11, it can reduce the temperature of the indoor unit chamber 11 and prevent the temperature of the indoor unit chamber 11 from being too high. Of course, when the air flow channel 21 communicates with the indoor unit chamber 11 and the outdoor unit chamber 12, it may also include only the first air flow channel 211 or the second air flow channel 212. Of course, when the air flow channel 21 communicates with the indoor unit chamber 11 and the outdoor unit chamber 12, it may also include only the first air flow channel 211 or the second air flow channel 212.

[0062] In some embodiments, the first air flow channel 211 and the second air flow channel 212 are used as one-way flow channels.

[0063] In some embodiments, in the embodiment where the air flow channel 21 includes the first air flow channel 211 and the second air flow channel 212, refer to Figure 1 As shown, when the indoor unit 10 cooperates with the outdoor unit 20 to heat the indoor unit chamber, the first air flow channel 211 may be adjacent to the top of the experimental equipment, and the second air flow channel 212 may be adjacent to the bottom of the experimental equipment. Here, since the first air flow channel 211 introduces the hotter air into the colder air, based on the characteristic that hot air rises, setting the first air flow channel 211 upwards is beneficial to introducing the hotter air into the colder air. Similarly, based on the characteristic that cold air sinks, setting the second air flow channel 212 downwards is beneficial for the second air flow channel 212 to introduce the colder air into the hotter air.

[0064] In some embodiments, in the embodiment where the air flow channel 21 includes the first air flow channel 211 and the second air flow channel 212, refer to Figure 2As shown, when the indoor unit 10 and the outdoor unit 20 cooperate to cool the indoor unit room, the first air flow channel 211 can be adjacent to the bottom of the experimental equipment, and the second air flow channel 212 can be adjacent to the top of the experimental equipment. Here, since the second air flow channel 212 introduces hotter air into colder air, based on the characteristic that hot air rises, setting the second air flow channel 212 higher is beneficial for introducing hotter air into colder air. Similarly, based on the characteristic that cold air sinks, setting the first air flow channel 211 lower is beneficial for the first air flow channel 211 to introduce colder air into hotter air.

[0065] Of course, in other embodiments, both the first air flow channel 211 and the second air flow channel 212 can be adjacent to the top of the experimental equipment. In this way, the higher position can avoid other components from blocking the first air flow channel 211 and the second air flow channel 212, and can realize the centralized arrangement of the first air flow channel 211 and the second air flow channel 212.

[0066] In some embodiments of the present disclosure, referring to Figure 1 and Figure 2 as shown, the air flow channel 21 can be provided with a plugging and adjusting member 3. The above heat transfer control structure can include this plugging and adjusting member 3. The plugging and adjusting member 3 is used to open or close the air flow channel 21, or adjust the opening degree of the air flow channel 21 during air circulation. In this way, when it is necessary to use the air flow channel 21 for heat exchange, the plugging and adjusting member 3 can be made to open the air flow channel 21. At this time, by adjusting the opening degree of the air flow channel 21, the heat exchange efficiency can be adjusted. When the opening degree of the air flow channel 21 is increased, the heat exchange efficiency can be increased. When the opening degree of the air flow channel 21 is decreased, the heat exchange efficiency can be decreased. Thus, the flexible adjustment of the heat exchange efficiency can be realized. Correspondingly, when it is necessary to stop using the air flow channel 21 for heat exchange, the air flow channel 21 can be closed, thereby improving the reliability of the experimental equipment for air conditioners.

[0067] In some embodiments of the present disclosure, referring to Figure 1 、 Figure 2 、 Figure 5 and Figure 7As shown, the blocking and adjusting member 3 can be rotatably connected to the air flow channel 21. That is to say, the blocking and adjusting member 3 can open or close the air flow channel 21 by rotation. Here, the air flow channel 21 can be connected with a stop structure 4, and the blocking and adjusting member 3 and the stop structure 4 are detachably lapped. Among them, when the blocking and adjusting member 3 is disengaged from or spaced apart from the stop structure 4, the blocking and adjusting member 3 is in the open position for opening the air flow channel 21. When the blocking and adjusting member 3 is lapped with the stop structure 4, the blocking and adjusting member 3 is in the closed position for closing the air flow channel 21. At this time, since the blocking and adjusting member 3 is lapped with the stop structure 4, the stop structure 4 will restrict the blocking and adjusting member 3 from rotating in the opposite direction to open the air flow channel 21. Thus, self-locking of the blocking and adjusting member 3 can be achieved. When at least one of the first air flow channel 211 and the second air flow channel 212 is provided with the blocking and adjusting member 3 and the stop structure 4, it can be ensured that the first air flow channel 211 and the second air flow channel 212 are used as one-way flow channels.

[0068] It should be noted that when the blocking and adjusting member 3 rotates clockwise to open the air flow channel 21, the above-mentioned opposite side refers to counterclockwise rotation. When the blocking and adjusting member 3 rotates counterclockwise to open the air flow channel 21, the above-mentioned opposite side refers to clockwise rotation.

[0069] In some embodiments of the present disclosure, referring to Figure 5 and Figure 7 As shown, the blocking and adjusting member 3 can include a plurality of blocking and adjusting plates 31 that are detachably lapped. The plurality of blocking and adjusting plates 31 are all rotatably connected to the air flow channel 21. In this way, when the plurality of blocking and adjusting plates 31 open the air flow channel 21 simultaneously, the flow area of the air flow channel 21 can be increased. Among them, the innermost blocking and adjusting plate 31 and the stop structure 4 are detachably lapped. In this way, when the plurality of blocking and adjusting plates 31 close the air flow channel 21, the plurality of blocking and adjusting plates 31 are lapped together, and the innermost blocking and adjusting plate 31 is lapped with the stop structure 4. At this time, such a setting can prevent the plurality of blocking and adjusting plates 31 from rotating in the opposite direction to open the air flow channel 21.

[0070] It should be noted that the innermost blocking and adjusting plate 31 can be understood as the blocking and adjusting plate 31 that opens or closes the air flow channel 21 last among the plurality of blocking and adjusting plates 31.

[0071] In some embodiments, referring to Figure 5 As shown, the stop structure 4 can be configured as a stop protrusion. Of course, referring to Figure 7 As shown, the stop structure 4 can also be configured as a protrusion protruding from the air flow channel 21. The present disclosure does not impose too many restrictions on this.

[0072] In some embodiments of the present disclosure, referring to Figure 8As shown, a rotation and reset structure 5 may be connected between the plugging and adjusting member 3 and the air flow channel 21. The rotation and reset structure 5 is used to reset the plugging and adjusting member 3 to close the air flow channel 21. That is to say, when the plugging and adjusting member 3 opens the air flow channel 21, the rotation and reset structure 5 can store the reset force. When it is necessary to close the air flow channel 21, the rotation and reset structure 5 can use the reset force to reset the plugging and adjusting member 3 to close the air flow channel 21. Thus, reliable closing of the air flow channel 21 by the plugging and adjusting member 3 can be achieved.

[0073] In some embodiments, referring to Figure 8 As shown, the rotation and reset structure 5 may be configured as a rotating shaft. The rotation axis of the rotating shaft extends in the horizontal direction, and the rotation axis is located above the center of gravity of the plugging and adjusting member 3. In this way, when the plugging and adjusting member 3 opens the air flow channel 21, part of the gravity of the plugging and adjusting member 3 can be converted into the above-mentioned reset force through the rotating shaft. Thus, it is beneficial for the rotating shaft to cooperate with the gravity of the plugging and adjusting member 3 to achieve automatic reset of the plugging and adjusting member 3.

[0074] In some other embodiments, the rotation and reset structure 5 may also be configured as an elastic reset structure. The elastic reset structure may have an elastic force to drive the plugging and adjusting member 3 to close the air flow channel 21. That is to say, when the plugging and adjusting member 3 opens the air flow channel 21, the elastic reset structure can store the above-mentioned elastic force to achieve automatic reset of the plugging and adjusting member 3. Among them, the elastic reset structure may be configured as a torsion spring to adapt to the rotation of the plugging and adjusting member 3. Of course, the elastic reset structure may also be configured as a tension spring.

[0075] In some embodiments of the present disclosure, referring to Figure 1 and Figure 2 As shown, a plugging and adjusting member 3 is provided in the air flow channel 21. The plugging and adjusting member 3 is used to open or close the air flow channel 21, or adjust the opening degree of the air flow channel 21 during air circulation. Among them, plugging and adjusting members 3 may be connected to both the first air flow channel 211 and the second air flow channel 212. The opening direction of the plugging and adjusting member 3 at the first air flow channel 211 is opposite to the opening direction of the plugging and adjusting member 3 at the second air flow channel 212. Here, since the first air flow channel 211 and the second air flow channel 212 are used as one-way flow channels and their flow directions are opposite, therefore, the opening direction of the plugging and adjusting member 3 at the first air flow channel 211 is opposite to the opening direction of the plugging and adjusting member 3 at the second air flow channel 212. On the one hand, it can adapt to the flow of the respective air. On the other hand, self-locking of each plugging and adjusting member 3 can be achieved. For example, when the plugging and adjusting member 3 is lapped with the stop structure 4, it can prevent the plugging and adjusting member 3 from rotating in the opposite side, thereby accidentally opening the first air flow channel 211 or the second air flow channel 212. Among them, the plugging and adjusting member 3 may be rotatably connected to the first air flow channel 211 or the second air flow channel 212.

[0076] In some embodiments of the present disclosure, with reference to Figure 1 and Figure 2 as shown, an air duct 21 may be connected to a blower 6, and the heat transfer control structure may include the blower 6, and the blower 6 is used to provide power for air flow. In this way, the rotation of the blower 6 can drive the air flow, and thus the reliability and efficiency of heat exchange can be improved. Among them, when a blocking and adjusting member 3 is provided in the air duct 21 and the rotation reset structure 5 is configured as a rotating shaft, when the blower 6 is started, at this time, the blower 6 can drive the air flow, and then the air can push the blocking and adjusting member 3 to open the air duct 21. Correspondingly, when the blower 6 stops working, the blocking and adjusting member 3 can be reset to close the air duct 21 under the action of gravity.

[0077] In some embodiments of the present disclosure, with reference to Figure 1 and Figure 3 as shown, at least one of the first air duct 211 and the second air duct 212 is provided with a blower 6, and the blower 6 is used to provide power for air flow. The rotation of the blower 6 can drive the air flow, and thus the reliability of heat exchange can be improved. Among them, in some embodiments, the first air duct 211 may be provided with a blower 6, and the second air duct 212 may be omitted from being provided with a blower 6, or the second air duct 212 may be provided with a blower 6, and the first air duct 211 may be omitted from being provided with a blower 6, or both the first air duct 211 and the second air duct 212 may be provided with a blower 6.

[0078] Next, the present disclosure will introduce the specific use process of the air duct 21 in combination with the above specific embodiments. With reference to Figure 1 and Figures 3 to 8As shown, when the indoor unit 10 and the outdoor unit 20 cooperate for heating, and when heat exchange between the indoor unit chamber 11 and the outdoor unit chamber 12 is required, the fan 6 in the first air flow channel 211 is started. The fan 6 pushes open a plurality of blocking and adjusting plates 31 on the first air flow channel 211, allowing the air in the indoor unit chamber 11 to flow into the outdoor unit chamber 12. After that, the air in the outdoor unit chamber 12 becomes positive pressure, and then this positive pressure air pushes open a plurality of blocking and adjusting plates 31 on the second air flow channel 212, allowing the air in the outdoor unit chamber 12 to flow into the indoor unit chamber 11. At this time, heat exchange between the indoor unit chamber 11 and the outdoor unit chamber 12 can be achieved. Additionally, since the air in the indoor unit chamber 11 enters the outdoor unit chamber 12 while the air in the outdoor unit chamber 12 also enters the indoor unit chamber 11, the above arrangement can also achieve air pressure balance in the indoor unit chamber 11 and air pressure balance in the outdoor unit chamber 12. When it is necessary to stop the heat exchange between the indoor unit chamber 11 and the outdoor unit chamber 12, the fan 6 is stopped. At this time, the rotating shaft can convert the gravity of the blocking and adjusting plates 31 into a restoring force, causing the plurality of blocking and adjusting plates 31 to automatically reset to close the first air flow channel 211 or the second air flow channel 212. After that, the setting of the stop structure 4 can achieve self-locking of the blocking and adjusting plates 31.

[0079] Similarly, referring to Figures 2 to 8 As shown, when the indoor unit 10 and the outdoor unit 20 cooperate for cooling, and when heat exchange between the indoor unit chamber 11 and the outdoor unit chamber 12 is required, the fan 6 in the second air flow channel 212 is started. The fan 6 pushes open a plurality of blocking and adjusting plates 31 on the second air flow channel 212, allowing the air in the outdoor unit chamber 12 to flow into the indoor unit chamber 11. After that, the air in the indoor unit chamber 11 becomes positive pressure, and then this positive pressure air pushes open a plurality of blocking and adjusting plates 31 on the first air flow channel 211, allowing the air in the indoor unit chamber 11 to flow into the outdoor unit chamber 12. At this time, heat exchange between the indoor unit chamber 11 and the outdoor unit chamber 12 can be achieved. Additionally, since the air in the indoor unit chamber 11 enters the outdoor unit chamber 12 while the air in the outdoor unit chamber 12 also enters the indoor unit chamber 11, the above arrangement can also achieve air pressure balance in the indoor unit chamber 11 and air pressure balance in the outdoor unit chamber 12. When it is necessary to stop the heat exchange between the indoor unit chamber 11 and the outdoor unit chamber 12, the fan 6 is stopped. At this time, the rotating shaft can convert the gravity of the blocking and adjusting plates 31 into a restoring force, causing the plurality of blocking and adjusting plates 31 to automatically reset to close the first air flow channel 211 or the second air flow channel 212. After that, the setting of the stop structure 4 can achieve self-locking of the blocking and adjusting plates 31.

[0080] In some embodiments of the present disclosure, referring to Figure 1 and Figure 2As shown, the experimental device may further be provided with an external heat exchange channel 7 for exchanging heat between the experimental device and the external environment. In this way, by using the heat exchange, i.e., thermal exchange, between the experimental device and the external environment, it is convenient to adjust the temperature of the indoor unit chamber 11 or the outdoor unit chamber 12 in the experimental device.

[0081] Among them, in some embodiments, referring to Figure 1 and Figure 2 as shown, the external heat exchange channel 7 may include an external air intake channel 71 and an external air outlet channel 72. The external air intake channel 71 is used to allow the air outside the experimental device to enter the experimental device, for example, to enter the indoor unit chamber 11 or the outdoor unit chamber 12 of the experimental device. The external air outlet channel 72 is used to allow the air inside the experimental device to flow out to the outside of the experimental device, for example, to flow out of the indoor unit chamber 11 or the outdoor unit chamber 12 of the experimental device. Thus, by using the heat exchange between the experimental device and the external air, it is possible to prevent the temperature in the indoor unit chamber 11 from being too high or too low, or prevent the temperature in the outdoor unit chamber 12 from being too low or too high. In addition, the arrangement of the external air intake channel 71 and the external air outlet channel 72 can also ensure the air pressure balance of the experimental device and avoid air pressure fluctuations. Among them, in some other embodiments, the external heat exchange channel 7 may also only include the external air intake channel 71, and the external air intake channel 71 is used to allow the air outside the experimental device to enter the experimental device. In this way, the external air and the air inside the experimental device are mixed to achieve the effect of adjusting the temperature inside the experimental device.

[0082] In some embodiments of the present disclosure, referring to Figure 1 and Figure 2 as shown, the external air intake channel 71 may communicate with one of the indoor unit chamber 11 and the outdoor unit chamber 12, and the external air outlet channel 72 communicates with one of the indoor unit chamber 11 and the outdoor unit chamber 12. In this way, when it is necessary to lower or raise the temperature of the indoor unit chamber 11, the external air intake channel 71 may communicate with the indoor unit chamber 11. At this time, the external air outlet channel 72 may communicate with any one of the indoor unit chamber 11 and the outdoor unit chamber 12. Similarly, when it is necessary to raise or lower the temperature of the outdoor unit chamber 12, the external air intake channel 71 may communicate with the outdoor unit chamber 12, and the external air outlet channel 72 may communicate with any one of the indoor unit chamber 11 and the outdoor unit chamber 12. In some embodiments, a wind valve may be provided at the external air intake channel 71, and the wind valve is used to open or close the external air intake channel 71. In this way, the flexible opening and closing of the external air intake channel 71 can be realized. Here, the opening and closing principle of the wind valve is well known to those skilled in the art, and the present disclosure will not elaborate herein.

[0083] In some embodiments, referring to Figure 1 and Figure 2As shown, both the external air intake passage 71 and the external air outlet passage 72 can communicate with the external machine room 12. In this way, the heat exchange between the external machine room 12 and the outside, such as the outside atmosphere, can be quickly achieved to rapidly increase or decrease the temperature of the external machine room 12.

[0084] In some embodiments, referring to Figure 1 and Figure 2 As shown, the external air intake passage 71 is adjacent to the bottom of the external machine room 12, and the external air outlet passage 72 is adjacent to the top of the external machine room 12. Here, when the indoor unit 10 and the outdoor unit 20 cooperate for refrigeration, the temperature of the external machine room 12 is usually higher, higher than the temperature of the outside atmosphere. Therefore, setting the external air intake passage 71 lower is conducive to the automatic entry of relatively cold air from the outside into the external machine room 12. Similarly, setting the external air outlet passage 72 higher is conducive to the automatic discharge of relatively hot air in the external machine room 12 to the outside, such as the outside atmosphere. When the indoor unit 10 and the outdoor unit 20 cooperate for heating, the above setting facilitates the air in the external machine room 12 to be discharged from the top of the external machine room 12. Of course, when the indoor unit 10 and the outdoor unit 20 cooperate for heating, the external air intake passage 71 can be adjacent to the top of the external machine room 12, and the external air outlet passage 72 can be adjacent to the bottom of the external machine room 12. In this way, since the air temperature in the external machine room 12 is relatively low, such a setting facilitates the automatic discharge of the air in the external machine room 12 to the outside atmosphere and the automatic entry of the air in the outside atmosphere into the external machine room 12.

[0085] Optionally, referring to Figure 1 and Figure 2 As shown, the external air outlet passage 72 can be connected with a fan 6, and the fan 6 is used to send the air in the external machine room 12 to the outside of the experimental equipment. In this way, the heat exchange efficiency between the external machine room 12 and the outside of the experimental equipment can be further improved.

[0086] In some embodiments of the present disclosure, referring to Figure 1 and Figure 2 As shown, a heat exchange device 8 is provided in one of the indoor machine room 11 and the outdoor machine room 12, and the heat exchange device 8 is used to heat or cool the air. In this way, the heat exchange device 8 can directly heat or cool the air in the indoor machine room 11 or the outdoor machine room 12. Thus, it is also possible to prevent the temperature in the indoor machine room 11 from being too high or too low, or prevent the temperature in the outdoor machine room 12 from being too low or too high.

[0087] In some embodiments of the present disclosure, the heat exchange device 8 can be configured as an air conditioning system, that is, the heat exchange device 8 can blow hot air or cold air to heat or cool the air in the indoor unit chamber 11 or the outdoor unit chamber 12. Among them, since the heat transfer channel 2 is used for heat exchange, the heat exchange device 8 is not mainly used to provide a low-temperature environment or a high-temperature environment for the outdoor unit 20. Therefore, setting the heat exchange device 8 can also reduce the energy consumption during air conditioning experiments. Of course, in other embodiments, the heat exchange device 8 can include a heat exchange medium, which can be configured as a medium with good thermal conductivity and large specific heat capacity. Thus, the air can also be heated or cooled.

[0088] In some embodiments of the present disclosure, as shown in Figure 3 a partition wall 100 is provided between the indoor unit chamber 11 and the outdoor unit chamber 12. The partition wall 100 is connected with a mounting bracket 91, and the indoor unit 10 is fixed to the mounting bracket 91. In this way, the indoor unit 10 can be conveniently suspended on the partition wall 100. At this time, the indoor unit 10 can be configured as a wall-mounted unit. Here, in some embodiments, as shown in Figure 1 and Figure 2 in the embodiment where the experimental equipment includes the first air flow channel 211 and the second air flow channel 212, both the first air flow channel 211 and the second air flow channel 212 can be provided on the partition wall 100 and can penetrate through the partition wall 100 to communicate the indoor unit chamber 11 and the outdoor unit chamber 12.

[0089] In some embodiments of the present disclosure, the experimental equipment can be provided with a refrigerant outlet (not shown in the figure), and the refrigerant outlet is used to discharge the refrigerant leaked from the indoor unit 10 or the outdoor unit 20. In this way, the refrigerant can be prevented from remaining in the indoor unit chamber 11 or the outdoor unit chamber 12, thereby endangering the health of the test personnel. In addition, preventing the refrigerant from remaining in the indoor unit chamber 11 or the outdoor unit chamber 12 can also have an explosion-proof effect on the indoor unit chamber 11 or the outdoor unit chamber 12, avoiding an explosion when the concentration of the refrigerant remaining in the indoor unit chamber 11 or the outdoor unit chamber 12 reaches a certain level.

[0090] In some embodiments of the present disclosure, the temperature of the indoor unit chamber 11 can be configured to be 16°C - 32°C, for example, it can be 23°C - 28°C. Specifically, for example, it can be 24°C, 25°C, 26°C, 27°C, etc. That is to say, the indoor unit chamber 11 can be generally configured as a constant temperature chamber.

[0091] In some embodiments of the present disclosure, when the indoor unit 10 and the outdoor unit 20 cooperate for heating, the temperature of the outdoor unit chamber 12 can be configured to be -35°C - 10°C, for example, it can be -16°C - (-1)°C. Specifically, for example, it can be -15°C, -10°C, -5°C, etc. That is to say, the outdoor unit chamber 12 can be generally configured as a low-temperature chamber to test the performance of the outdoor unit 20 in this temperature range.

[0092] In some embodiments of the present disclosure, when the indoor unit 10 cooperates with the outdoor unit 20 for refrigeration, the temperature of the outdoor unit chamber 12 can be configured to be 25°C - 65°C, for example, it can be 44°C - 56°C. Specifically, for example, it can be 45°C, 50°C, 55°C, etc. That is to say, the outdoor unit chamber 12 can be generally constructed as a high-temperature chamber to test the performance of the outdoor unit 20 within this temperature range.

[0093] In some embodiments of the present disclosure, in one of the indoor unit chamber 11 and the outdoor unit chamber 12, a pressure balance structure can be provided. The pressure balance structure can include an air tank and an air suction structure and an air release structure connected to the air tank. The air suction structure is used to suck the air in the indoor unit chamber 11 or the outdoor unit chamber 12 into the air tank, and the air release structure is used to release the air in the air tank into the indoor unit chamber 11 or the outdoor unit chamber 12. Thus, it can help maintain the air pressure balance in the indoor unit chamber 11 or the outdoor unit chamber.

However, the present disclosure is not limited to the specific details in the above embodiments.

[0095] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0096] In addition, any combination can be made between various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
