[0055] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0056] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0057] The present disclosure provides a control method for an air-conditioning experimental system. The control method is based on such an air-conditioning experimental system: Figure 5 As shown, the air-conditioning experimental system includes: an indoor machine room 100, a first outdoor machine room 200 and a second outdoor machine room 300. The indoor machine room 100 is provided with a first heat exchanger 1 and a second heat exchanger 2, the first outdoor machine room 200 is provided with a first outdoor unit 3, and the second outdoor machine room 300 is provided with a second outdoor unit 4. The first heat exchanger 1 and the first outdoor unit 3 cooperate to heat the indoor machine room 100, and the second heat exchanger 2 and the second outdoor unit 4 cooperate to cool the indoor machine room 100.

[0058] The internal machine room 100 is used to accommodate the first heat exchanger 1 and the second heat exchanger 2 and simulate a normal temperature environment, the target temperature range of which can be set to 16°C~32°C, for example; the first external machine room 200 is used to accommodate the first external machine 3 and simulate a low temperature environment, the target temperature range of which can be -35°C~10°C, for example; the second external machine room 300 is used to accommodate the second external machine 4 and simulate a high temperature environment, the target temperature range of which can be 25°C~65°C, for example. That is, the experimental system disclosed in the present invention can simultaneously perform long-term operation tests of the internal machine under normal temperature and long-term operation tests of the external machine in extreme environments including low temperature and high temperature, so as to obtain parameters such as the loss of components of the internal machine and the external machine under long-term operation, and further improve the design.

[0059] Specifically, the first heat exchanger 1 and the first external machine 3 cooperate to heat the internal machine room 100, and the first external machine 3 cools the first external machine room 200 to provide a low temperature environment for the first external machine 3 itself. Similarly, the second heat exchanger 2 and the second external machine 4 cooperate to cool the internal machine room 100, and the second external machine 4 heats the second external machine room 300 to provide a high temperature environment for the second external machine 4 itself. The internal machine room 100 has the first heat exchanger 1 for heating and the second heat exchanger 2 for cooling running at the same time, so that the internal machine room 100 is in a normal temperature environment. The internal machine room 100, the first external machine room 200 and the second external machine room 300 can all be provided with a thermal insulation layer.

[0060] In some embodiments, the first heat exchanger 1 and the second heat exchanger 2 can be respectively arranged in one indoor unit, that is, the first heat exchanger 1 and the second heat exchanger 2 are separately arranged, the first heat exchanger 1 can be arranged in the first indoor unit, and the second heat exchanger 2 can be arranged in the second indoor unit. In this case, the first indoor unit cooperates with the first outdoor unit 3 for heating, and the second indoor unit cooperates with the second outdoor unit 3 for cooling. In other embodiments, the first heat exchanger 1 and the second heat exchanger 2 can also be centrally arranged. For example, the first heat exchanger 1 and the second heat exchanger 2 can be integrated in the casing of one indoor unit, and the first heat exchanger 1 and the second heat exchanger 2 are separated to perform independent heat exchange.

[0061] Different from the related art that tests the operation of air conditioners in an open environment, the air conditioner experimental system provided by the present disclosure places both the indoor and outdoor units inside the corresponding machine rooms, so that the variable temperature long-term operation of the air conditioner can be achieved without being restricted by the ambient temperature. This variable temperature long-term operation has low requirements for the selection of the time node of the test, and because it can run for a long time, it is also beneficial to shorten the test cycle. In addition, the generation of the test environment temperature of the indoor machine room 100, the first outdoor machine room 200 and the second outdoor machine room 300 is achieved by generating heat by the operation of the air conditioner itself, which is also beneficial to saving energy.

[0062] Taking into account the possibility of temperature imbalance between the indoor and outdoor units during long-term operation and deviating from the target temperature range during the test, specifically, as the heating process continues, the temperature of the first outdoor unit chamber 200 is gradually decreasing, and will drop below its target temperature range for a long time, which may cause the first outdoor unit 3 to shut down protectively. Similarly, as the cooling process continues, the temperature of the second outdoor unit chamber 300 is gradually increasing, and will rise above the target temperature range for a long time, which may cause the second outdoor unit 4 to shut down protectively.

[0063] Based on this, Figure 1As shown, the control method provided by the present disclosure includes: S1, obtaining the first current temperature of any one of the indoor unit room, the first outdoor unit room and the second outdoor unit room during operation; and S2, based on the obtained first current temperature of the indoor unit room, the first outdoor unit room and the second outdoor unit room, controlling the air-conditioning experimental system to adjust one of the indoor unit room, the first outdoor unit room and the second outdoor unit room to the first target temperature range corresponding to each other.

[0064] It should be noted that during operation, the internal machine room 100, the first external machine room 200, and the second external machine room 300 all have their respective first current temperatures. Similarly, during operation, the internal machine room 100, the first external machine room 200, and the second external machine room 300 all have their respective first target temperature intervals. As mentioned above, the first target temperature interval of the internal machine room 100 may be, for example, 16°C to 32°C, the first target temperature interval of the first external machine room 200 may be, for example, -35°C to 10°C, and the first target temperature interval of the second external machine room 300 may be, for example, 25°C to 65°C.

[0065] The control method provided by the present invention enables the internal machine room 100, the first external machine room 200 and the second external machine room 300 to always remain in the first target temperature range of the test during the operation of the experimental system, avoiding temperature imbalance during the operation of the air conditioner and deviating from the first target temperature range, which is beneficial to improving the reliability of the test results.

[0066] Any one of the internal machine room 100 , the first external machine room 200 , and the second external machine room 300 may be adjusted to the first target temperature range corresponding to each other in various ways.

[0067] In some embodiments, Figure 2 As shown, according to the first current temperature of the internal machine room, the first external machine room, and the second external machine room, the step of controlling the air-conditioning experimental system so that one of the internal machine room, the first external machine room, and the second external machine room is adjusted to the first target temperature range corresponding to each other includes: S21, controlling the internal machine room and the first external machine room to transfer heat to adjust the first current temperature of the internal machine room and / or the first current temperature of the first external machine room; and / or controlling the internal machine room and the second external machine room to transfer heat to adjust the first current temperature of the internal machine room and / or the first current temperature of the second external machine room. That is, in this embodiment, the adjustment of the first current temperature is achieved by transferring heat between the internal machine room 100 and the first external machine room 200, and / or transferring heat between the internal machine room 100 and the second external machine room 300.

[0068] In other embodiments, Figure 3As shown, according to the first current temperature of any one of the internal machine room, the first external machine room and the second external machine room, the step of controlling the air conditioning experimental system to adjust any one of the internal machine room, the first external machine room and the second external machine room to the first target temperature range corresponding to each other also includes: S22, controlling the first external machine room and the second external machine room to transfer heat to adjust the first current temperature of the first external machine room and / or the first current temperature of the second external machine room. That is, in this embodiment, the adjustment of the first current temperature is achieved by transferring heat between the first external machine room 200 and the second external machine room 300.

[0069] Heat is transferred to any two of the inner machine room 100, the first outer machine room 200 and the second outer machine room 300, wherein the heat used for the transfer and exchange is generated when the inner and outer machines are working, and the heat transfer occurs between the insides of the machine rooms, thereby achieving the target temperature of each machine room to be maintained without the aid of additional energy-consuming equipment such as operating condition machines, which is beneficial to saving electricity consumption, reducing costs and being environmentally friendly and energy-saving.

[0070] The heat exchange between the chambers includes air exchange, that is, the air in one of the inner chamber 100, the first outer chamber 200, and the second outer chamber 200 flows into the other, thereby achieving air exchange. Such air exchange can be achieved, for example, by providing an air flow channel for air circulation, the air flow channel connecting the inner chamber 100, the first outer chamber 200, and the second outer chamber 200. Figure 5 and Figure 6 As shown, an example of setting an air flow channel on the wall between the inner machine room 100 and the first outer machine room 200 is used for explanation. The air flow channel may include a first air flow channel 5 and a second air flow channel 6. The first air flow channel 5 is used to allow the air in the inner machine room 100 to flow into the first outer machine room 200. The air flow direction is Figure 5 As shown by the solid arrow, the second air flow channel 6 is used to allow the air in the first external machine room 200 to flow into the internal machine room 100, and the air flow direction is Figure 5 As shown by the dashed arrow in the middle, a similar air flow passage may be provided between the inner machine room 100 and the second outer machine room 300, which will not be described in detail here.

[0071] The first air flow channel 5 and the second air flow channel 6 can be configured as a one-way channel or a two-way channel. The one-way channel only allows air to flow from one machine room to another, and the reverse flow of air is prevented, for example, by setting a one-way valve, or by using a blower with a directional rotating guide plate. The two-way channel does not limit the air flow direction.

[0072] A heat exchange fan can be set at the first air flow channel 5. After the first air flow channel 5 is opened, starting the heat exchange fan can provide power for the flow of air. The second air flow channel 6 can be configured to control the air of the inner machine room 100 to flow into the first outer machine room 200 through the first air flow channel 5, while allowing the air of the first outer machine room 200 to flow back through the second air flow channel 6, so as to achieve the heat transfer function and maintain the balance of gas pressure in either one. In detail, the air in the inner machine room 100 flows into the first outer machine room 200 through the first air flow channel 5. At this time, the air pressure in the first outer machine room 200 will be greater than that in the inner machine room 100, so that the air in the first outer machine room 200 flows back to the inner machine room 100 through the second air flow channel 6. At this time, the second air flow channel 6 has the functions of heat transfer and air pressure balance at the same time. It should be noted that in order to balance the air pressure of each machine room, in addition to setting the second air flow channel 6, each machine room can also be connected to the external environment to maintain air pressure balance.

[0073] The following is an exemplary introduction to the control method of heat transfer between the inner machine chamber 100 and the first outer machine chamber 200, heat transfer between the inner machine chamber 100 and the second outer machine chamber 300, and heat transfer between the first outer machine chamber 200 and the second outer machine chamber 300.

[0074] Regarding the heat transfer between the inner machine chamber 100 and the first outer machine chamber 200. In some embodiments, the step of controlling the heat transfer between the inner machine chamber and the first outer machine chamber includes: S211, when the first current temperature of the inner machine chamber is higher than the upper limit of the first target temperature range of the inner machine chamber, controlling the heat of the first outer machine chamber to be transferred to the inner machine chamber. Specifically, when the first current temperature of the inner machine chamber 100 is higher than the upper limit of its first target temperature range, the temperature of the first outer machine chamber 200 is reduced to within the first target temperature range by allowing the air with lower temperature in the inner machine chamber 100 to flow into the inner machine chamber 100. It should be noted that the lower and higher here are relative to the temperatures of the air in the two chambers undergoing heat exchange, and are comparative values ​​of the two rather than absolute values.

[0075] In other embodiments, the step of controlling heat transfer between the inner machine chamber and the first outer machine chamber includes: S212, when the first current temperature of the first outer machine chamber is lower than the lower limit of the first target temperature range of the first outer machine chamber and is greater than the low temperature threshold, controlling the heat of the inner machine chamber to be transferred to the first outer machine chamber; when the first current temperature of the first outer machine chamber is lower than the low temperature threshold, first controlling the heat of the second outer machine chamber to be transferred to the inner machine chamber, and then controlling the heat of the inner machine chamber to be transferred to the first outer machine chamber.

[0076] Specifically, when the first current temperature of the first external machine room 200 is lower than the lower limit of its first target temperature range and greater than the low temperature threshold, the air in the internal machine room 100 flows into the first external machine room 200, which is sufficient to raise the temperature in the first external machine room 200 to its first target temperature range. When the first current temperature of the first outdoor machine 200 is lower than the low temperature threshold, the air inflow from the internal machine room 100 alone is not sufficient to raise the temperature in the first external machine room 200 to its first target temperature range, and at this time, the higher temperature air in the second external machine room 300 can flow into the first external machine room 200. The low temperature threshold can be set by comprehensively considering factors such as the upper and lower limits of each target temperature range and the difference between the target temperature ranges of each machine room.

[0077] The air in the second external machine room 300 may first enter the internal machine room 100, and then enter the first external machine room 200. Of course, the air in the second external machine room 300 may also enter the first external machine room 200 directly without passing through the internal machine room 100, which may be achieved by arranging the internal machine room 100, the first external machine room 200, and the second external machine room 300, such as inline arrangement or inverse arrangement, or by a jumper pipe between the first external machine room 200 and the second external machine room 300.

[0078] Regarding the heat transfer between the inner machine room 100 and the second outer machine room 300. In some embodiments, the step of controlling the inner machine room and the second outer machine room to transfer heat includes: S213, when the first current temperature of the inner machine room is lower than the lower limit of the first target temperature range of the inner machine room, controlling the heat of the second outer machine room to transfer to the inner machine room. Specifically, when the first current temperature of the inner machine room 100 is lower than the lower limit of its first target temperature range, the temperature of the inner machine room 100 is raised to within the first target temperature range by allowing the air with a higher temperature in the second outer machine room 300 to flow into the inner machine room 100.

[0079] In other embodiments, the step of controlling the heat transfer between the inner machine room and the second outer machine room further includes: S214, when the first current temperature of the second outer machine room is higher than the upper limit of the first target range of the second outer machine room, controlling the heat of the inner machine room to transfer to the second outer machine room. Specifically, when the first current temperature of the second outer machine room 300 is higher than the upper limit of the first target temperature range, the temperature of the second outer machine room 300 is reduced to within the first target temperature range by allowing the air with a lower temperature in the inner machine room 100 to flow into the second outer machine room 300.

[0080] Regarding the heat transfer between the first external machine chamber 200 and the second external machine chamber 300. In some embodiments, the step of controlling the heat transfer between the first external machine chamber and the second external machine chamber includes: S221, when the first current temperature of the first external machine chamber is lower than the lower limit of the target temperature range of the first external machine chamber, the heat of the second external machine chamber is transferred to the first external machine chamber. Specifically, when the first current temperature of the first external machine chamber 200 is lower than the lower limit of its first target temperature range, the temperature of the second external machine chamber 300 is increased to within the first target temperature range by allowing the air with a higher temperature in the first external machine chamber 200 to flow into the first external machine chamber 200.

[0081] In other embodiments, the step of controlling the first external machine chamber and the second external machine chamber to transfer heat includes: S222, when the first current temperature of the second external machine chamber is higher than the upper limit of the first target temperature interval of the second external machine chamber, the heat of the first external machine chamber is transferred to the second external machine chamber. Specifically, when the first current temperature of the second external machine chamber 300 is higher than the upper limit of its first target temperature interval, the temperature of the second external machine chamber 300 is reduced to within the first target temperature interval by allowing the air with a lower temperature in the first external machine chamber 200 to flow into the second external machine chamber 300.

[0082] In addition to the above-mentioned method of transferring heat between the rooms to control the air-conditioning experimental system so that one of the inner room, the first outer room and the second outer room is adjusted to the first target temperature range corresponding to each other, Figure 4 As shown, the step of controlling the air-conditioning experimental system to adjust one of the indoor machine room, the first outdoor machine room, and the second outdoor machine room to the first target temperature range corresponding to each other also includes: S23, controlling one of the indoor machine room, the first outdoor machine room, and the second outdoor machine room to transfer heat to the outside of the experimental system, that is, the heat transfer is achieved by introducing fresh air from the external environment into the machine room while exhausting part of the original air. The outside of the experimental system here refers to the environmental space outside the machine room.

[0083] In some embodiments, the step of controlling heat transfer between any one of the inner machine room, the first outer machine room, and the second outer machine room and the outside of the experimental system includes: S231, when the first current temperature of the inner machine room deviates from the target temperature range, the air outside the experimental system flows into the inner machine room, and is discharged from any one of the inner machine room, the first outer machine room, and the second outer machine room to the outside of the experimental system. The deviation here refers to being higher than the upper limit of the target temperature range or lower than the lower limit of the target temperature. In this embodiment, both the air intake and the air outlet can be set in the inner machine room 100, or the air intake is set in the inner machine room 100 and the air outlet is set in the first outer machine room 200, or the air intake is set in the inner machine room 100 and the air outlet is set in the second outer machine room 300. By setting the air intake in the inner machine room 100, fresh air can be directly introduced into the inner machine room 100 to improve the efficiency of heat transfer.

[0084] In other embodiments, the step of controlling heat transfer between any one of the inner machine room, the first outer machine room, and the second outer machine room and the outside of the experimental system includes: S232, when the first current temperature of the first outer machine room deviates from the first target temperature range, allowing air outside the laboratory to flow into the first outer machine room, and to be discharged from any one of the inner machine room, the first outer machine room, and the second outer machine room to the outside of the experimental system. In this embodiment, both the air intake and the air outlet can be set in the first outer machine room 200, or the air intake is set in the first outer machine room 200 and the air outlet is set in the inner machine room 100, or the air intake is set in the first outer machine room 200 and the air outlet is set in the second outer machine room 300. In the arrangement scheme of a straight line, the air outlet of the first outer machine room 200 can be discharged first through the inner machine room 100 and then through the second outer machine room 300. By setting the air intake in the first outer machine room 200, fresh air can be directly introduced into the first outer machine room 200 to improve the efficiency of heat transfer.

[0085] In other embodiments, the step of controlling heat transfer between any one of the inner chamber, the first outer chamber, and the second outer chamber and the outside of the experimental system includes: S233, when the first current temperature of the second outer chamber deviates from the first target temperature interval, air outside the experimental system flows in from the second outer chamber, and is discharged outside the experimental system from any one of the inner chamber, the first outer chamber, and the second outer chamber. Wherein, step S2331 includes: when the first current temperature of the second outer chamber is higher than the upper limit of the first target temperature interval, air outside the experimental system flows in from the second outer chamber, and is discharged outside the experimental system from the second outer chamber, that is, both the air inlet and the air outlet are set in the second outer chamber 300. In other embodiments, the air inlet may be set in the second outer chamber 300, and the air outlet may be set in the inner chamber 100 or the first outer chamber 200.

[0086] In the above-mentioned implementation mode in which both the air inlet and the air outlet are arranged in the second external machine chamber 300, further, step S23311 is included: when the first current temperature of the second external machine chamber is higher than the upper limit of the first target temperature range, and the first current temperatures of the internal machine chamber and the first external machine chamber do not deviate from the corresponding first target temperature range, the air outside the experimental system is made to flow into the second external machine chamber, and is discharged from the second external machine chamber to the outside of the experimental system. Specifically, even if the temperature of the second external machine chamber 300 meets its own needs, but the temperatures in the internal machine chamber 100 and the first external machine chamber 200 are already within their target temperature ranges, the air in the second external machine chamber 300 It will not be forced to flow into the inner machine chamber 100, but will be discharged to the external environment; when the first current temperature of the second external machine chamber is higher than the upper limit of the target temperature range, and the first current temperature of one of the inner machine chamber and the first external machine chamber is lower than the corresponding lower limit of the first target temperature range, the air intake and outlet of the second external machine chamber for heat transfer with the outside of the experimental system are closed. Specifically, when the first current temperature of one of the inner machine chamber 100 and the first external machine chamber 200 is lower than the corresponding lower limit of the first temperature target range, the higher temperature air in the second external machine chamber 300 will preferentially meet the needs of the inner machine chamber 100 and the first external machine chamber 200 without exchanging heat with the external environment.

[0087] In some embodiments, the inner machine room 100, the first outer machine room 200 and the second outer machine room 300 are all provided with a heat exchange device, and the control method includes: S24, when one of the inner machine room, the first outer machine room and the second outer machine room deviates from the corresponding first target temperature interval, the heat exchange device is started to heat or cool the air in the room. The heat exchange device can be, for example, a working condition machine, or it can also be a device capable of cooling or heating, such as an air conditioning system. For example, when the temperature in the first outer machine room 200 is lower than the lower limit of its first target temperature, the heat exchange device directly heats the air in the first outer machine room 200. It should be noted that the aforementioned first heat exchanger 1, the second heat exchanger 2, the first outer machine 3 and the second outer machine 4 are the tested equipment, and the heat exchange device including the air conditioning system, etc. here is used as a device for simulating the test environment.

[0088] The air conditioner also has certain requirements for the conditions when it is started. For example, before the air conditioner is operated, if the temperature in the indoor machine room 100 is high, the first heat exchanger 1 used for heating will not work. Considering this problem, in some embodiments, the control method also includes: S3, obtaining the second current temperature of the indoor machine room before operation; S4, according to the second current temperature of the indoor machine room, controlling the air conditioner experimental system, operating one of the first heat exchanger and the second heat exchanger, and adjusting it to the corresponding second target temperature range; and S5, after the temperature of the indoor machine room reaches the second target temperature range, operating the other of the first heat exchanger and the second heat exchanger. Among them, the second current temperature is the temperature of each machine room before the air conditioner is operated, and the second target temperature is the temperature at which one of the first heat exchanger 1 and the second heat exchanger 2 can start working normally.

[0089] For example, the second current temperature in the indoor machine room 100 before the air conditioner is running is higher than the upper limit of its second target temperature range. At this time, the first heat exchanger 1 does not work and the entire experimental system cannot run. The second heat exchanger 2 can be started first for cooling until the temperature in the indoor machine room 100 drops to the second target temperature range. At this time, the first heat exchanger 1 can already work, and then the first heat exchanger 1 is turned on and gradually cooperates with the second heat exchanger 2 to keep the indoor machine room 100 at normal temperature. The second current temperature in the indoor machine room 100 before the air conditioner is running is less than the lower limit of the second target temperature range. The control method is similar and will not be repeated here.
