[0045] Using the technical solution of this application, the cabinet serves to fix and protect the components installed inside. The refrigeration system is mainly used to realize the refrigeration cycle function of the air conditioning system. The refrigeration system includes a compressor, an evaporator, and a condenser. The evaporator is mainly used to absorb heat from the air in the first cabinet. When the return air flows through the evaporator, the refrigerant inside evaporates from a liquid state to a gaseous state. This process requires the absorption of a large amount of heat, thereby cooling the air in the first cabinet. The compressor is used to drive the flow of refrigerant and compress the low-temperature, low-pressure gaseous refrigerant from the evaporator into a high-temperature, high-pressure gas, enabling the refrigerant to effectively release heat in the condenser. The condenser is used to cool the high-temperature, high-pressure gaseous refrigerant compressed by the compressor and convert it into a liquid state. The heat released by the refrigerant in this process is discharged. The refrigerant is brought to the outdoor environment and cooled back to a liquid state. Then, it is sent back to the evaporator to evaporate and absorb heat, thus completing a refrigeration cycle. The first fan drives the airflow and is positioned corresponding to the air supply outlet, which connects the first cabinet to the indoor environment. The first fan blows the air cooled by the refrigeration system from the first cabinet into the indoor environment, thereby reducing the indoor temperature. The return air outlet is located on the second cabinet, connecting the indoor environment and the second cabinet, ensuring that the hot air in the indoor environment can flow back into the cabinet due to the pressure difference between the indoor environment and the cabinet. The air supply outlet and the return air outlet are located on the same side of the cabinet, connecting the cabinet to the indoor environment, thereby ensuring that the air can circulate between the indoor environment and the cabinet. After being cooled by the refrigeration system, the air is blown into the room through the air outlet by the fan, further cooling the room. Under air pressure, the hot air on the side of the room furthest from the air outlet flows back into the server rack through the return air vent, is cooled again, and is then blown back into the room, thus achieving air circulation. By placing the evaporator in the air circulation path between the air outlet and return air vent inside the server rack, the air is brought into maximum contact with the evaporator during circulation, thereby improving the evaporator's cooling effect. The air conditioning system provided in this application allows for indoor cooling by placing the refrigeration system in an outdoor server rack, eliminating the need for indoor units inside the data center. This avoids the air conditioning system occupying server room space, improves the utilization rate of server room space, reduces the difficulty and cost of air conditioning system installation, and ultimately reduces data center operating costs.

[0057] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0058] Referring to Figures 1 to 9, this application provides an air conditioning system, including a cabinet 1, which is located outdoors and includes a first cabinet 11 and a second cabinet 12, which communicate with each other; a ventilation opening, including an air supply outlet 27 and a return air outlet 28, wherein the air supply outlet 27 connects the indoor unit to the first cabinet 11, and the return air outlet 28 is located on the second cabinet 12 and connects the indoor unit to the second cabinet 12, and the air supply outlet 27 and the return air outlet 28 are located on the same side of the cabinet 1; a fan 6, including a first fan 61, which is located corresponding to the air supply outlet 27 and supplies air towards the air supply outlet 27; and a refrigeration system, including a compressor 32, an evaporator 31 and a condenser 33, wherein the evaporator 31 and the compressor 32 are located inside the first cabinet 11, the condenser 33 is located outside the first cabinet 11, and the evaporator 31 is located between the air supply outlet 27 and the return air outlet 28.

[0059] In the above technical solution, the cabinet 1 is used to fix and protect the components installed inside the cabinet 1.

[0060] The refrigeration system is mainly used to realize the refrigeration cycle function of the air conditioning system. The refrigeration system includes a compressor 32, an evaporator 31, and a condenser 33. The evaporator 31 is mainly used to absorb the heat of the air in the first cabinet 11. When the return air flows through the evaporator 31, the refrigerant inside the evaporator 31 will evaporate from liquid to gas. This process requires the absorption of a large amount of heat, thereby cooling the air in the first cabinet 11. The compressor 32 is used to drive the flow of refrigerant and compress the low-temperature, low-pressure gaseous refrigerant from the evaporator 31 into a high-temperature, high-pressure gas, so that the refrigerant can effectively release heat in the condenser 33. The condenser 33 is used to cool the high-temperature, high-pressure gaseous refrigerant compressed by the compressor 32 and convert it into a liquid. During this process, the heat released by the refrigerant is discharged to the outdoor environment and cooled back into a liquid. Then the refrigerant is sent back to the evaporator 31 to evaporate and absorb heat, thereby completing a refrigeration cycle. The first fan 61 is used to drive airflow. The first fan 61 is set to the air supply outlet 27 to supply air to the air supply outlet 27, which connects the first cabinet 11 to the room. The first fan 61 blows the air cooled by the cooling system in the first cabinet 11 into the room, thereby reducing the room temperature. The return air outlet 28 is set on the second cabinet 12 to connect the room and the second cabinet 12, ensuring that the hot air in the room can flow back into the cabinet 1 under the action of the gas pressure difference between the room and the cabinet 1. The cooling system is set in the outdoor cabinet 1. One side of the cabinet 1 is attached to the outer wall of the data center. The air supply outlet 27 and the return air outlet 28 are both set on the side of the cabinet 1 close to the outer wall of the data center, so that the cabinet 1 is connected to the indoor data center, thereby ensuring that the air can circulate between the indoor room and the cabinet 1, which facilitates the external placement of the cooling system.

[0061] After being cooled by the refrigeration system, the air is blown into the room through the air outlet 27 by the fan to cool the room. Under the action of air pressure, the hot air on the side of the room away from the air outlet 27 flows back to the cabinet 1 through the return air outlet 28, is cooled again, and is blown into the room again, thus realizing the circulation of cooling air. By placing the evaporator 31 in the air circulation path between the air outlet 27 and the return air outlet 28 in the cabinet 1, the air is made to come into contact with the evaporator 31 as much as possible during the circulation process, thereby improving the cooling effect of the evaporator 31 on the air.

[0062] The air conditioning system of this application embodiment can cool the indoor temperature by setting the refrigeration system in the outdoor cabinet 1, without the need to set up indoor units inside the data center. This avoids the air conditioning system occupying the computer room space, improves the utilization rate of the computer room space, and reduces the installation difficulty and cost of the air conditioning system, thereby achieving the effect of reducing the operating cost of the data center.

[0063] In one embodiment of this application, the air conditioning system further includes a partition 4, which includes a first partition 41. The ventilation openings also include a first ventilation opening 21 and a second ventilation opening 22. The first ventilation opening 21 is disposed on the first cabinet 11 and connects the outside to the first cabinet 11. The first partition 41 separates the first cabinet 11 from the second cabinet 12. The second ventilation opening 22 is disposed on the first partition 41 and connects the first cabinet 11 to the second cabinet 12. The air conditioning system also includes a ventilation valve 7, which includes a first ventilation valve 71. The first ventilation valve 71 is disposed at the second ventilation opening 22. The evaporator 31 divides the first cabinet 11 into a first chamber 51 and a second chamber 52. The first ventilation opening 21 connects the outside to the first chamber 51. The air outlet 27 connects the inside to the second chamber 52. The second ventilation opening 22 connects the second chamber 52 to the second cabinet 12.

[0064] In the above technical solution, the first partition 41 serves to physically isolate the first cabinet 11 and the second cabinet 12. The first partition 41, in conjunction with the second vent 22 and the first ventilation valve 71 located on it, controls the supply and return air paths. In the air conditioner's cooling mode, indoor return air enters through the return air inlet 28 and, guided by the first partition 41 and the second vent 22, flows to the evaporator 31 for cooling. In the mixed cooling mode and natural cooling mode, outdoor fresh air enters through the first vent 21. The first partition 41 and the closed first ventilation valve 71 isolate the first cabinet 11 and the second cabinet 12, restricting the flow path of the outdoor fresh air. This allows the outdoor fresh air to pass through the first filter 91 and the evaporator 31, preventing outdoor air from flowing towards the return air inlet 28 and interfering with the flow path of the returning hot air. Simultaneously, after the first partition 41 separates the first cabinet 11 and the second cabinet 12, it reduces the heat exchange area of ​​the cabinet containing the evaporator 31, thereby further improving the cooling effect and reducing cooling energy consumption.

[0065] The first vent 21 is used to introduce outdoor air. When the outdoor temperature is suitable for the air conditioning system to enter the natural cooling mode or the mixed cooling mode, the low-temperature outdoor air can directly enter the first cabinet 11 through the first vent 21 and then be sent into the room for cooling by the fan.

[0066] The second vent 22 is provided on the first partition 41 to connect the first cabinet 11 and the second cabinet 12, thereby increasing the cooling channel space and allowing the air returning to the second cabinet 12 to return to the evaporator 31 of the first cabinet 11 for cooling through the second vent 22.

[0067] The first ventilation valve 71 is used to control the opening and closing of the second ventilation port 22, thereby adjusting the airflow path. When the room is cooled by natural cooling mode or mixed cooling mode, the first ventilation valve 71 is closed to separate the first cabinet 11 and the second cabinet 12, preventing hot air from entering the first cabinet 11 from the second cabinet 12 through the second ventilation port 22, thus reducing the effect of natural cooling. When the air conditioner cooling mode is used, the first ventilation valve 71 is opened to allow the airflow to flow through the evaporator 31 in the first cabinet 11 before flowing into the room, thereby improving the cooling effect of the evaporator 31 on the circulating airflow.

[0068] The evaporator 31 divides the first cabinet 11 into a first chamber 51 and a second chamber 52, so that the airflow must pass through the evaporator 31 from the first chamber 51 to the second chamber 52, thereby improving the cooling effect of the evaporator 31 on the circulating airflow in the air conditioner cooling mode and the mixed cooling mode.

[0069] In one embodiment of this application, the ventilation valve 7 further includes a third ventilation valve 73, which is disposed on the first ventilation port 21.

[0070] In the above technical solution, the third ventilation valve 73 is used to control the opening and closing of the first ventilation port 21, thereby adjusting the air circulation path. When the air conditioning system enters the air conditioner cooling mode, the third ventilation valve 73 is closed to prevent the outdoor air with a higher temperature from entering the first cabinet 11 and adding extra burden to the cooling system. When the air conditioner enters the mixed cooling mode or the natural cooling mode, the third ventilation valve 73 is opened to allow the outdoor air with a lower temperature to enter the first cabinet 11 through the first ventilation port 21 and participate in the cold air circulation, thereby reducing the cooling energy consumption of the air conditioning system.

[0071] In one embodiment of this application, the ventilation opening further includes a third ventilation opening 23 and a fourth ventilation opening 24, the partition 4 further includes a second partition 42, the ventilation valve 7 further includes a second ventilation valve 72, and the fan 6 further includes a second fan 62. The second partition 42 divides the second cabinet 12 into a third chamber 53 and a fourth chamber 54. The return air vent 28 connects the indoor space with the third chamber 53. The second ventilation opening 22 is disposed on the first partition 41 and connects the third chamber 53 with the first chamber 51. The third ventilation opening 23 is disposed on the second partition 42 and connects the third chamber 53 with the fourth chamber 54. The second ventilation valve 72 is disposed on the third ventilation opening 23. The fourth ventilation opening 24 is disposed on the fourth chamber 54 and connects the fourth chamber 54 with the outside. The second fan 62 is disposed on the fourth ventilation opening 24 and supplies air to the outside.

[0072] In the above technical solution, the second partition 42 divides the second cabinet 12 into a third chamber 53 and a fourth chamber 54. The second vent 22 provided on the second partition 42 is used to connect the third chamber 53 and the fourth chamber 54. The second ventilation valve 72 is provided on the third vent 23 to control the opening and closing of the third vent 23, thereby adjusting the air path. The fourth vent 24 is used to connect the fourth chamber 54 with the outside, realizing air circulation between the fourth chamber 54 and the outside, which helps to dissipate heat. The second fan 62 is provided on the fourth vent 24 to send air to the outside, further accelerating the efficiency of air exchange between the fourth chamber 54 and the outside, and improving the heat dissipation effect. When the air conditioning system is in air conditioner cooling mode, the second ventilation valve 72 is closed, allowing the hot air returning to the second cabinet 12 to enter the first chamber 51 from the third chamber 53 through the second ventilation port 22 for cooling. At the same time, the second fan 62 works, allowing outside air to enter the fourth chamber 54 through the sixth ventilation port 26, passing through the first condenser 331, and then being discharged to the outside through the fourth ventilation port 24, thereby improving the heat dissipation effect of the first condenser 331. When the air conditioning system is in mixed cooling mode and natural cooling mode, the first ventilation valve 71 is closed and the second ventilation valve 72 is opened, allowing the hot air returning to the second cabinet 12 to enter the fourth chamber 54 from the third chamber 53 through the second ventilation port 22. At the same time, the second fan 62 works, discharging the hot air in the fourth chamber 54 to the outside.

[0073] In one embodiment of this application, the cabinet 1 further includes a third cabinet 13, the partition 4 further includes a third partition 43 and a fourth partition 44, and the ventilation opening further includes a fifth ventilation opening 25. The third partition 43 separates the first cabinet 11 and the third cabinet 13. The fourth partition 44 is disposed inside the third cabinet 13, dividing the third cabinet 13 into a fifth chamber 55 and a sixth chamber 56. The fifth ventilation opening 25 is disposed on the third partition 43 and connects the second chamber 52 and the sixth chamber 56. The air outlet 27 is disposed on the third cabinet 13 and connects the sixth chamber 56 and the room. The first fan 61 is disposed at the fifth ventilation opening 25 and supplies air to the room.

[0074] In the above technical solution, the third partition 43 is used to separate the first cabinet 11 and the third cabinet 13, preventing the cold air in the first cabinet 11 from mixing with the hot air in the sixth chamber 56 of the third cabinet 13, which would affect the cooling effect of the air conditioning system. Simultaneously, through the cooperation of the third partition 43 with the fifth vent 25 and the air outlet 27, the flow path of the cooling airflow is restricted, providing a circulation channel for the cooling airflow. This allows the cold air, after being cooled by the evaporator 31, to enter the fifth chamber 55 through the fifth vent 25 and then enter the room through the air outlet 27. The fourth partition 44 is located inside the third cabinet 13. By separating the fifth chamber 55 and the sixth chamber 56, it prevents the cold air from mixing with the outside air that participates in heat dissipation, restricts the airflow area, and achieves orderly airflow guidance. The fifth vent 25 is set on the third partition 43 and connects the second chamber 52 and the sixth chamber 56, so that the cold air cooled by the evaporator 31 can enter the sixth chamber 56 from the second chamber 52 through the fifth vent 25. The first fan 61 is used to blow the cold air entering the sixth chamber 56 into the room through the air outlet 27, which improves the air supply efficiency.

[0075] In one embodiment of this application, the condenser 33 includes a first condenser 331, which is disposed in the fourth chamber 54. A sixth vent 26 is provided on the side wall of the fourth chamber 54, and the sixth vent 26 connects the fourth chamber 54 to the outside.

[0076] In the above technical solution, the first condenser 331 is mainly used for heat dissipation, so that the high-temperature and high-pressure gaseous refrigerant compressed by the compressor 32 is cooled and converted into liquid. The sixth vent 26 connects the fourth chamber 54 with the outside, so that the outdoor air passes through the first condenser 331 through the sixth vent 26 into the fourth chamber 54, and then is discharged to the outside through the fourth vent 24, realizing air convection and thereby improving the heat dissipation effect of the first condenser 331.

[0077] In one embodiment of this application, the condenser 33 includes a second condenser 332, which is disposed in a fifth chamber 55, and a seventh vent 29 is provided on the side wall of the fifth chamber 55.

[0078] In the above technical solution, the second condenser 332 is mainly used for heat dissipation, so that the high-temperature and high-pressure gaseous refrigerant compressed by the compressor 32 is cooled and converted into liquid. The seventh vent 29 connects the fifth chamber 55 with the outside, so that the outdoor air passes through the second condenser 332 through the seventh vent 29 into the fifth chamber 55, and then is discharged to the outside through the eighth vent 30, realizing air convection and thus improving the heat dissipation effect of the second condenser 332.

[0079] In one embodiment of this application, the ventilation opening further includes an eighth ventilation opening 30, and the fan 6 further includes a third fan 63. The eighth ventilation opening 30 is disposed on the fifth chamber 55 and connects the fifth chamber 55 with the outside. The third fan 63 is disposed on the eighth ventilation opening 30 to supply air to the outside.

[0080] In the above technical solution, the third fan 63 is installed on the eighth ventilation port 30 to send air to the outside, which further accelerates the efficiency of air exchange between the fifth chamber 55 and the outside and improves the heat dissipation effect of the second condenser 332.

[0081] In one embodiment of this application, the air conditioning system further includes a filter, the filter including a first filter 91 disposed on the first vent 21.

[0082] In the above technical solution, the first filter 91 is installed on the first vent 21 to perform preliminary filtration on the air entering the first chamber 51 from the outside through the first vent 21, so as to prevent dust and other impurities from the outside from entering the cabinet 1 with the air and causing pollution to the air conditioning system and the room.

[0083] In one embodiment of this application, the filter includes a second filter 92 disposed on the side of the evaporator 31 facing the first chamber 51.

[0084] In the above technical solution, since the evaporator 31 is located in the flow path of the cooling airflow, the second filter 92 is located on the side of the evaporator 31 facing the first chamber 51 to filter all the air passing through the evaporator 31 again. On the one hand, this improves the cleanliness of the air flowing into the room and avoids outdoor impurities from contaminating the indoor equipment. On the other hand, it also avoids the problem of impurities covering the surface of the evaporator 31, which would lead to an increase in the cooling energy consumption of the air conditioning system.

[0085] In one embodiment of this application, the air conditioning system further includes sensors, including a first temperature sensor and a second temperature sensor, wherein the first temperature sensor is located outdoors and the second temperature sensor is located at the return air vent 28.

[0086] In the above technical solution, the first temperature sensor monitors the outdoor temperature, and the second temperature sensor is set at the return air vent 28, so that the second temperature sensor is as far away as possible from the cold air at the supply air vent 27, reducing the interference of cooling gas on the second temperature sensor, thereby improving the authenticity and accuracy of the indoor temperature monitored by the second temperature sensor.

[0087] In one embodiment of this application, the compressor 32 is disposed within the first chamber 51.

[0088] In the above technical solution, by placing the compressor 32 in the first chamber 51, the compressor 32 is kept as far away from the room as possible, reducing the interference of noise and vibration to the indoor machine room. In addition, the return air or outdoor fresh air flowing through the first chamber 51 can also dissipate heat from the compressor 32, preventing the compressor 32 from being in an overheated state for a long time, thereby improving the stability and service life of the compressor 32.

[0089] In one embodiment of this application, the cabinet 1 further includes a third cabinet 13, and the first cabinet 11, the second cabinet 12 and the third cabinet 13 have the same length along the indoor air supply direction.

[0090] In the above technical solution, the first cabinet 11, the second cabinet 12 and the third cabinet 13 have the same length along the indoor air supply direction. The first cabinet 11, the second cabinet 12 and the third cabinet 13 with the same length are easy to arrange into an integrated cabinet group. At the same time, the overall appearance is more neat and beautiful after the cabinet group is arranged. In addition, after multiple cabinets with the same length are stacked, the overall unit can also have good stability.

[0091] In one embodiment of this application, the cabinet 1 further includes a third cabinet 13, wherein the first cabinet 11, the second cabinet 12 and the third cabinet 13 are arranged horizontally as a horizontal cabinet; or, the first cabinet 11, the second cabinet 12 and the third cabinet 13 are arranged vertically as a vertical cabinet.

[0092] In the above technical solution, the arrangement of the first cabinet 11, the second cabinet 12 and the third cabinet 13 can be adjusted so that the first cabinet 11, the second cabinet 12 and the third cabinet 13 are arranged horizontally as horizontal cabinets or vertically as vertical cabinets. The horizontal or vertical cabinet arrangement allows the air conditioning system to adapt to different installation environments. For example, when the ground space is limited, a vertical arrangement can be selected, while when the height is limited, a horizontal arrangement can be selected, which is suitable for various building types and spatial layouts.

[0093] In one embodiment of this application, multiple horizontal cabinets are stacked or multiple vertical cabinets are installed side by side.

[0094] In the above technical solution, multiple horizontal cabinets can be stacked or multiple vertical cabinets can be installed side by side as needed. This installation method not only saves space, but also allows for flexible adjustment of the system's cooling capacity according to actual needs. It is suitable for scenarios that require rapid expansion or reduction of capacity, and also facilitates system maintenance and management.

[0095] In one embodiment of this application, the second partition 42 includes a parallel section and a guide section. The two parallel sections are respectively disposed at both ends of the guide section. The end of the parallel section away from the guide section extends along the width direction of the second cabinet 12 to the side wall of the second cabinet 12 and connects with the side wall. The two parallel sections are parallel to each other, and the guide section is an inclined surface.

[0096] In the above technical solution, the parallel section is used to install and fix the guide section inside the cabinet. The guide section is used to change the airflow direction, guide the airflow towards the vent, reduce the airflow resistance in the cabinet, and improve the airflow circulation efficiency of the system. The two parallel sections are parallel to each other, and the guide section is inclined, so that the second partition 42 forms a Z-shaped structure. This partition structure can significantly improve the space utilization of the third chamber 53 and the fourth chamber 54. At the same time, by adjusting the length of the parallel section, the direction of the inclined surface of the guide section can be adjusted, so that the inclined surface of the guide section is more accurately oriented towards the vent, further improving the accuracy and efficiency of airflow.

[0097] In one embodiment of this application, the fourth partition 44 includes a parallel section and a guide section. The two parallel sections are respectively disposed at both ends of the guide section. The end of the parallel section away from the guide section extends along the width direction of the third cabinet 13 to the side wall of the third cabinet 13 and connects with the side wall. The two parallel sections are parallel to each other, and the guide section is an inclined surface.

[0098] In the above technical solution, the parallel section is used to install and fix the guide section inside the cabinet. The guide section is used to change the airflow direction and guide the airflow toward the vent. The two parallel sections are parallel to each other, and the guide section is inclined, so that the fourth partition 44 forms a Z-shaped structure. This partition structure can significantly improve the space utilization of the fifth chamber 55 and the sixth chamber 56. At the same time, by adjusting the length of the parallel section, the direction of the inclined surface of the guide section can be adjusted so that the inclined surface of the guide section is more accurately oriented toward the vent, further improving the accuracy and efficiency of airflow.

[0099] In one embodiment of this application, the air conditioning system further includes a wiring hole 8, which is disposed on the cabinet 1.

[0100] In the above technical solution, multiple horizontal cabinets are stacked or multiple vertical cabinets are installed side by side. The cables between the cabinets are run through the cable holes 8, which improves the convenience of installation. At the same time, hiding the cables inside the cabinets also makes the cabinets look cleaner and more aesthetically pleasing.

[0101] Referring to Figures 1 to 9, this application provides a cooling method for an air conditioning system, comprising:

[0102] Acquire outdoor and indoor temperature data;

[0103] The air conditioning system is controlled to enter different cooling modes based on outdoor and indoor temperature data.

[0104] Cooling modes include: air conditioner cooling mode, hybrid cooling mode, and natural cooling mode.

[0105] In the above technical solution, outdoor temperature data is obtained through the first temperature sensor of the air conditioning system, and indoor temperature data is obtained through the second temperature sensor. Based on the outdoor and indoor temperature data, the air conditioning system is controlled to enter the air conditioner cooling mode, the mixed cooling mode, or the natural cooling mode. This cooling method can intelligently select the cooling mode according to the temperature difference between the outdoor and indoor environments, thereby improving energy utilization efficiency and reducing operating costs.

[0106] In one embodiment of this application, the step of controlling the air conditioning system to enter different cooling modes based on outdoor temperature data and indoor temperature data includes:

[0107] The outdoor temperature data and indoor temperature data are compared to determine whether the air conditioning system should be switched to cooling mode.

[0108] If the outdoor temperature is greater than or equal to the indoor temperature, the air conditioning system will be switched to cooling mode.

[0109] If the outdoor temperature data is lower than the indoor temperature data, the difference between the outdoor and indoor temperature data is calculated based on the outdoor and indoor temperature data, and the temperature difference is compared with the mixed cooling temperature difference threshold and the natural cooling temperature difference threshold. The cooling mode of the air conditioning system is selected based on the comparison results.

[0110] If the temperature difference is greater than or equal to the mixed cooling temperature difference threshold and less than or equal to the natural cooling temperature difference threshold, the air conditioning system is controlled to enter the mixed cooling mode.

[0111] If the temperature difference is less than the mixed cooling temperature difference threshold, the air conditioning system will be controlled to enter the air conditioner cooling mode.

[0112] If the temperature difference exceeds the natural cooling temperature difference threshold, the air conditioning system will be switched to natural cooling mode.

[0113] In the above technical solution, when the outdoor temperature data is greater than or equal to the indoor temperature data, the air conditioner cooling mode is used to cool the indoor temperature, avoiding the entry of high outdoor temperature air into the cabinet and adding extra cooling burden to the air conditioning system; when the outdoor temperature data is less than the indoor temperature data, the difference between the outdoor and indoor temperature data is compared with the mixed cooling temperature difference threshold and the natural cooling temperature difference threshold to select the cooling mode with lower energy consumption under the current indoor and outdoor temperature conditions.

[0114] When the temperature difference is greater than or equal to the mixed cooling temperature difference threshold and less than or equal to the natural cooling temperature difference threshold, the air conditioning system is controlled to enter the mixed cooling mode. At this time, directly introducing outdoor air with a lower temperature can have a certain cooling effect on the indoor temperature. However, since the temperature difference between indoor and outdoor is not large enough, the cooling effect of directly introducing outdoor air on the indoor temperature is limited and cannot reduce the indoor temperature to a suitable temperature. Therefore, the air conditioner needs to be turned on at the same time to participate in the cooling and further reduce the temperature of outdoor air and return hot air. At this time, the temperature of the mixed air in the first chamber 51 in the mixed cooling mode is lower than the temperature of the return hot air in the first chamber 51 in the air conditioner cooling mode. Therefore, the cooling load of the evaporator 31 is smaller in the mixed cooling mode, thereby reducing the cooling energy consumption of the air conditioning system.

[0115] When the temperature difference is less than the mixed cooling temperature difference threshold, the indoor and outdoor temperature difference is too small, and directly introducing outdoor air cannot significantly reduce the indoor temperature. In order to ensure a suitable and stable indoor temperature environment, the air conditioning system is controlled to enter the air conditioner cooling mode, thereby ensuring a good indoor cooling effect.

[0116] When the temperature difference exceeds the natural cooling temperature difference threshold, the air conditioning system enters the natural cooling mode. In this mode, there is no need to start the air conditioner for cooling. Simply introducing cooler outdoor air can effectively cool the indoor environment. Compared to the air conditioner's cooling mode and the hybrid cooling mode, the air conditioning system does not need to start the cooling system in the natural cooling mode, which greatly reduces the energy consumption and operating costs of the air conditioning system.

[0117] In one embodiment of this application, the step of controlling the air conditioning system to enter the air conditioner cooling mode includes:

[0118] Control the second ventilation valve 72 and the third ventilation valve 73 to close, and control the first ventilation valve 71 to open;

[0119] Control the first fan 61, the second fan 62 and the third fan 63 to be in operation;

[0120] The compressor 32 is controlled to be in operation.

[0121] In the above technical solution, the second ventilation valve 72 is closed, the first ventilation valve 71 is opened, and the compressor 32 is in operation. This allows the hot air in the room to flow back into the third chamber 53 through the return air vent 28, and then into the first chamber 51 through the second ventilation vent 22. In the first chamber 51, the hot air flows through the evaporator 31, thereby cooling the hot air and forming cold air at a lower temperature. At the same time, the third ventilation valve 73 is closed to prevent the hot outdoor air from entering the first chamber 51 and increasing the burden on the refrigeration system. The cooled air enters the second chamber 52, and the first fan 61 is in operation. Driven by the first fan 61, the cold air in the second chamber 52 is blown into the room through the air outlet 27, thereby reducing the indoor temperature.

[0122] The second fan 62 is controlled to be in operation, so that outdoor air enters the fourth chamber 54 through the first condenser 331 through the sixth vent 26, and then is discharged to the outside by the second fan 62 through the fourth vent 24, thereby realizing air circulation in the fourth chamber 54 and improving the heat dissipation effect of the first condenser 331.

[0123] The third fan 63 is controlled to be in operation, so that outdoor air enters the fifth chamber 55 through the seventh vent 29, passes through the second condenser 332, and is then discharged to the outside by the third fan 63 through the eighth vent 30, thereby realizing air circulation in the fifth chamber 55 and improving the heat dissipation effect of the second condenser 332.

[0124] In one embodiment of this application, the step of controlling the air conditioning system to enter a hybrid cooling mode includes:

[0125] Control the first ventilation valve 71 to close, and control the second ventilation valve 72 and the third ventilation valve 73 to open;

[0126] Control the first fan 61, the second fan 62 and the third fan 63 to be in operation;

[0127] The compressor 32 is controlled to be in operation.

[0128] In the above technical solution, the first ventilation valve 71 is closed, the second ventilation valve 72 is opened, and the second fan 62 is in operation. After the indoor hot air flows back into the third chamber 53, the hot air enters the fourth chamber 54 through the second ventilation valve 72 under the drive of the second fan 62. At the same time, the second fan 62 draws outside air into the fourth chamber 54 through the first condenser 331 from the sixth ventilation port 26, and then blows the hot air in the fourth chamber 54 out to the outside.

[0129] The third ventilation valve 73 is opened, the first fan 61 is put into operation, and the compressor 32 is put into operation. Driven by the first fan 61, outdoor air is drawn into the first chamber 51 through the first ventilation port 21. Then, the outdoor air passes through the evaporator 31 and is cooled by the evaporator 31 to form cold air at a lower temperature. The cooled cold air enters the second chamber 52. The first fan 61 blows the cold air in the second chamber 52 into the room through the air outlet 27, thereby reducing the indoor temperature.

[0130] The third fan 63 is controlled to be in operation, so that outdoor air enters the fifth chamber 55 through the seventh vent 29, passes through the second condenser 332, and is then discharged to the outside by the third fan 63 through the eighth vent 30, thereby realizing air circulation in the fifth chamber 55 and improving the heat dissipation effect of the second condenser 332.

[0131] In one embodiment of this application, the step of controlling the air conditioning system to enter natural cooling mode includes:

[0132] Control the first ventilation valve 71 to close, and control the second ventilation valve 72 and the third ventilation valve 73 to open;

[0133] Control the first fan 61 and the second fan 62 to be in operation, and control the third fan 63 to be in a stopped state;

[0134] The compressor 32 is controlled to be in a stopped state.

[0135] In the above technical solution, the first ventilation valve 71 is closed, the second ventilation valve 72 is opened, and the second fan 62 is in operation. After the indoor hot air flows back into the third chamber 53, the hot air enters the fourth chamber 54 through the second ventilation valve 72 under the drive of the second fan 62. At the same time, the second fan 62 draws outside air into the fourth chamber 54 through the first condenser 331 from the sixth ventilation port 26, and then blows the hot air in the fourth chamber 54 out to the outside.

[0136] The third ventilation valve 73 is opened, and the first fan 61 is put into operation. Driven by the first fan 61, outdoor air is drawn into the first chamber 51 through the first ventilation port 21. Then, the outdoor air passes through the evaporator 31 and enters the second chamber 52. The first fan 61 blows the outdoor air in the second chamber 52 into the room through the air outlet 27, thereby reducing the indoor temperature.

[0137] From the above description, it can be seen that the above embodiments of this application achieve the following technical effects: the cabinet 1 is used to fix and protect the components installed in the cabinet 1. The refrigeration system is mainly used to realize the function of the air conditioning system refrigeration cycle. The refrigeration system includes a compressor 32, an evaporator 31, and a condenser 33. The evaporator 31 is mainly used to absorb the heat of the air in the first cabinet 11. When the return air flows through the evaporator, the refrigerant inside will evaporate from liquid to gas. This process requires the absorption of a large amount of heat, thereby cooling the air in the first cabinet 11. The compressor 32 is used to drive the refrigerant flow and compress the low-temperature, low-pressure gaseous refrigerant from the evaporator 31 into a high-temperature, high-pressure gas, so that the refrigerant can effectively release heat in the condenser 33. The condenser 33 is used to cool the high-temperature, high-pressure gaseous refrigerant compressed by the compressor 32 and convert it into a liquid. During this process, the heat released by the refrigerant is discharged to the outdoor environment and cooled back into a liquid. Then the refrigerant is sent back to the evaporator 31 to evaporate and absorb heat, thereby completing a refrigeration cycle. The first fan 61 is used to drive the air flow. The first fan 61 corresponds to the airflow. Air vent 27 is provided to supply air to the room, which connects the first cabinet 11 to the interior. The first fan 61 blows the air cooled by the refrigeration system from the first cabinet 11 into the room, thereby lowering the indoor temperature. Return air vent 28 is provided on the second cabinet 12, connecting the interior to the second cabinet 12, ensuring that hot air from the room can return to the cabinet 1 due to the pressure difference between the interior and the cabinet. The supply air vent 27 and return air vent 28 are located on the same side of the cabinet 1, connecting the cabinet 1 to the interior, thus ensuring air circulation between the interior and the cabinet 1. After being cooled by the refrigeration system, the air is blown into the room through the air outlet 27 by the fan, cooling the room. Under the action of air pressure, the hot air in the room away from the air outlet 27 flows back to the cabinet 1 through the return air outlet 28, is cooled again, and is blown into the room again, thus realizing the circulation of cooling air. By placing the evaporator 31 in the air circulation path between the air outlet 27 and the return air outlet 28 in the cabinet 1, the air is made to come into contact with the evaporator 31 as much as possible during the circulation process, thereby improving the cooling effect of the evaporator 31 on the air.

[0138] The air conditioning system provided in this application can cool the indoor unit by placing the refrigeration system in the outdoor cabinet 1, without having to place the indoor unit inside the data center. This avoids the air conditioning system occupying the computer room space, improves the utilization rate of the computer room space, and reduces the installation difficulty and cost of the air conditioning system, thereby achieving the effect of reducing the operating cost of the data center.

[0139] The above descriptions are merely some embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
