Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and more specifically, to a cabinet air conditioner. Background Technology

[0002] Currently, with the rapid advancement of digital transformation, integrated rack-mount air conditioners have become indispensable key equipment in outdoor 5G base stations of communication facilities such as China Mobile, China Telecom, China Unicom, and China Tower, as well as in the new energy, power, and industrial sectors, due to their efficient heat dissipation, compact structure, and adaptability to harsh outdoor conditions. They not only effectively withstand outdoor challenges such as sun exposure, rain, dust, and fumes, but can also be directly embedded in outdoor base station cabinet doors, saving space and meeting stringent installation standards. In scenarios such as battery cabinets, outdoor cabinets, electrochemical energy storage cabinets, energy storage power stations, outdoor power cabinets, prefabricated power modules, and control cabinets, integrated rack-mount air conditioners solve the heat dissipation problems of high-density equipment through their efficient heat dissipation solutions, while significantly optimizing space utilization, energy consumption control, and operational efficiency. With the continuous development of AI and IoT technologies, the intelligence level of these air conditioners is increasing, and they are gradually becoming an important component supporting modern data centers and industrial automation.

[0003] However, most existing integrated cabinet air conditioning systems employ a closed-loop cooling mode, relying solely on return air for temperature and humidity control in the equipment room. This mode lacks a fresh air intake mechanism, leading to poor air circulation within the base station, increased carbon dioxide concentration, and the inability to promptly remove harmful gases and odors. Simultaneously, dust gradually accumulates within the equipment room, accelerating equipment aging and impacting the health of maintenance personnel. More importantly, the enclosed environment easily creates pressure differences between the inside and outside of the equipment room. Excessive pressure difference can exert additional stress on the equipment casing structure, causing deformation or seal failure, allowing external moisture, dust, and other contaminants to enter the equipment room, potentially causing short circuits or corrosion. Furthermore, some high-precision sensors and electronic components are extremely sensitive to pressure changes; excessive pressure differences will interfere with their normal function, affecting data accuracy. In extreme environments, excessive indoor-outdoor pressure differences pose significant challenges to the structural safety of base stations, the equipment operating environment, and daily maintenance.

[0012] Furthermore, a third positioning groove is provided on the inner peripheral wall of the air inlet duct, and a third positioning protrusion is provided on the outer peripheral wall of the third fan.

[0015] The present invention provides a cabinet air conditioner, comprising: a housing; a partition disposed within the housing to divide the inner cavity of the housing into a first air duct and a second air duct, wherein the housing is provided with a first air inlet and a first air outlet communicating with the first air duct, the first air inlet being for communicating with the outside and the first air outlet being for communicating with the inside; an evaporator and a first fan, wherein the first fan is disposed within the first air duct and located at the first air outlet, and the evaporator is disposed within the first air duct; and an air outlet assembly disposed within the first air duct, wherein the housing is provided with a second air inlet for communicating with the inside and a second air outlet for communicating with the outside, and the air outlet assembly is connected to the second air inlet and the second air outlet respectively, for discharging indoor air from the second air inlet through the second air outlet to the outside.

[0017] Furthermore, under suitable environmental conditions, such as when the outside temperature is low, natural cool air can be introduced through the first air inlet, thereby reducing the compressor's start-up and running time. Compressors and other equipment do not need to operate under high load for extended periods, and may even be shut down, extending their lifespan, reducing maintenance frequency, and thus lowering the overall energy consumption of the air conditioning system. Simultaneously, the optimized air circulation system reduces the risk of equipment overheating, helping to extend equipment lifespan and reduce long-term operating and maintenance costs.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To address the problem that existing cabinet air conditioners struggle to balance indoor and outdoor air pressure during air exchange, leading to increased air conditioning load and energy consumption, this invention provides a cabinet air conditioner.

[0031] Please refer to Figures 1 to 5As shown, the technical solution of this embodiment provides a cabinet air conditioner, including: a housing 1; a partition 2, disposed inside the housing 1 to divide the inner cavity of the housing 1 into a first air duct 7 and a second air duct 8, the housing 1 being provided with a first air inlet 101 and a first air outlet 102 communicating with the first air duct 7, the first air inlet 101 being used to communicate with the outside, and the first air outlet 102 being used to communicate with the inside; an evaporator 3 and a first fan 4, the first fan 4 being disposed inside the first air duct 7 and located at the first air outlet 102, the evaporator 3 being disposed inside the first air duct 7; and an air outlet assembly 10, disposed inside the first air duct 7, the housing 1 being provided with a second air inlet 103 for communicating with the inside and a second air outlet 104 for communicating with the outside, the air outlet assembly 10 being connected to the second air inlet 103 and the second air outlet 104 respectively, for discharging indoor air from the second air inlet 103 to the outside through the second air outlet 104.

[0032] By installing a partition 2 inside the casing 1, the space is effectively divided into a first air duct 7 and a second air duct 8, achieving zoned management of internal airflow. The first air duct 7 introduces cool outdoor air through the first air inlet 101, which, after being cooled by the evaporator 3, is sent into the room through the first air outlet 102 for heat exchange, thus achieving efficient heat dissipation for indoor equipment. This zoned heat dissipation method avoids the potential temperature fluctuations or direct introduction of pollutants that might result from directly sending outdoor air into the room, improving heat dissipation efficiency and environmental purification capabilities. The second air inlet 103 and the second air outlet 104, connected to the air outlet assembly 10, allow hot indoor air to flow directly from the second air inlet 103 through the second air outlet 104 to the outside, accelerating air circulation and exchange. This mechanism helps balance the air pressure inside and outside the computer room, reducing structural risks caused by pressure differences, while also improving indoor air quality, reducing carbon dioxide concentration and harmful gas content, and providing a healthier environment for equipment and maintenance personnel. This solves the problem in existing cabinet air conditioners that it is difficult to balance indoor and outdoor air pressure during air exchange, which leads to increased air conditioning load and energy consumption.

[0033] Furthermore, under suitable environmental conditions, such as when the outside temperature is low, natural cool air can be introduced through the first air inlet 101, thereby reducing the compressor's start-up and running time. The compressor and other equipment do not need to operate under high load for extended periods, and may even be shut down, extending their service life, reducing maintenance frequency, and thus lowering the overall energy consumption of the air conditioning system. At the same time, the optimized air circulation system reduces the risk of equipment overheating, helping to extend equipment life and reduce long-term operating and maintenance costs.

[0034] In this embodiment, the cabinet air conditioner further includes: a condenser 5, a compressor, and a fourth fan 6. The casing 1 is provided with a third air inlet 105 and a third air outlet 106 communicating with the second air duct 8. The fourth fan 6 is disposed within the second air duct 8 and located at the third air outlet 106. The condenser 5 and the compressor are disposed within the second air duct 8. Specifically, there are two third air inlets 105, each disposed on one of the two side walls of the casing 1. There are two condensers 5, disposed within the second air duct 8 and correspondingly located at the two third air inlets 105.

[0035] The above setup introduces outdoor air through the third air inlet 105, where it undergoes heat exchange with the compressor and condenser 5. The heat energy from the second air duct 8 is then output to the room through the third air outlet 106 via the fourth fan 6. By redesigning the structure and layout of the condenser 5 and evaporator 3, and optimizing the air duct design, the airflow velocity through the condenser 5 and evaporator 3 is made more uniform, ensuring that the heat removed by both is essentially the same, avoiding localized overheating or insufficient heat dissipation. Furthermore, the combined design of the second air duct 8 and the air outlet assembly 10 not only helps balance the air pressure inside and outside the server room, reducing structural risks caused by pressure differences and improving indoor air quality, but also reduces the compressor's operating time. With optimized ventilation, when the indoor temperature is high, equipment such as the compressor does not need to operate at high load for extended periods, and may even be shut down, extending their service life and reducing maintenance frequency. This design effectively enhances the thermal management capabilities of the rack air conditioner, ensuring that high-density equipment maintains a suitable operating temperature during operation, preventing safety issues and performance degradation caused by overheating.

[0036] In this embodiment, the first air duct 7 is also provided with a water receiving tray component and an electrical box component. The water receiving tray component is located below the evaporator 3, and the electrical box component and the first fan 4 are both installed on the inner wall of the casing 1.

[0037] In this embodiment, there are two first air outlets 102 on the casing 1, and the evaporator 3 and the first fan 4 are arranged in the first air duct 7 and are respectively arranged corresponding to the two first air outlets 102.

[0038] In this embodiment, as Figure 4 As shown, the air outlet assembly 10 includes: an air outlet duct 11 having a first port and a second port, the first port and the second port being respectively connected to a second air inlet 103 and a second air outlet 104; an air outlet cover 12 and a second fan 13, the air outlet cover 12 being movably connected to the second port for opening or closing the second port, and the second fan 13 being disposed inside the air outlet duct 11.

[0039] The movable design of the air outlet cover 12 allows it to open or close the second duct as needed, thereby precisely controlling the exhaust of indoor air. When indoor air quality is poor (e.g., high CO2 concentration, high dust levels) or when indoor humidity needs to be reduced, the air outlet cover 12 can be opened to accelerate indoor air circulation and renewal; conversely, when fresh air is not needed or the external environment is harsh, closing the air outlet cover 12 protects the equipment from external pollutants. The second fan 13 is located within the air outlet duct 11, serving as the driving force to propel indoor air through the second air inlet 103 and out through the second air outlet 104. Through intelligent control of the operation of the second fan 13, the fan speed and volume can be dynamically adjusted based on the heat generated by indoor equipment, occupant activity, or external environmental conditions, achieving intelligent airflow management and maintaining a stable and healthy indoor environment.

[0040] The coordinated operation of the air outlet cover 12 and the second fan 13 helps maintain air pressure balance inside and outside the computer room, preventing equipment structural deformation or sealing failure due to air pressure differences. Especially in high-altitude or extreme temperature environments, this design can effectively prevent equipment damage due to air pressure issues, improving the environmental adaptability and reliability of the cabinet air conditioner.

[0041] Specifically, the inner peripheral wall of the air outlet duct 11 is provided with a first positioning groove 110 communicating with the first pipe opening, and the outer peripheral wall of the second fan 13 near the first pipe opening is provided with a first positioning protrusion 130, which is adapted to be connected to the first positioning groove 110. The inner peripheral wall of the air outlet duct 11 located away from the first pipe opening is provided with a second positioning protrusion, and the outer peripheral wall of the second fan 13 away from the first pipe opening is provided with a second positioning groove 131, which is adapted to be connected to the second positioning groove 131.

[0042] The precise fit between the first positioning groove 110 and the first positioning protrusion 130, and between the second positioning protrusion and the second positioning groove 131, ensures stable installation of the second fan 13 within the air outlet duct 11 and limits the displacement of the second fan 13 along and around its axis within the air outlet duct 11. This design ensures the robustness of the second fan 13 during operation, reduces displacement or loosening caused by vibration or airflow impact, and enhances the reliability and durability of the system. Furthermore, it allows operators to quickly and accurately complete the installation and removal of the second fan 13 without additional tools, significantly reducing time and labor costs during assembly and maintenance.

[0043] It should be noted that, in this embodiment, the number of the first positioning protrusion 130, the first positioning groove 110, and the second positioning protrusion and the second positioning groove 131 can be multiple, and can be selected accordingly based on usage requirements and actual working conditions. Optionally, multiple first positioning grooves 110 and multiple second positioning protrusions are all spaced apart on the inner peripheral wall of the air outlet duct 11, and multiple first positioning protrusions 130 and multiple second positioning grooves 131 are all spaced apart on the outer peripheral wall of the second fan 13.

[0044] In this embodiment, the air outlet assembly 10 further includes: a first air guide duct 14, one end of which is detachably connected to the second air inlet 103, and the other end of the first air guide duct 14 is provided with a first external thread section on its outer peripheral wall, and the air outlet duct 11 is provided with a first internal thread section on its inner peripheral wall near the first pipe opening, so that after the first external thread section and the first internal thread section are connected, the end of the first air guide duct 14 away from the second air inlet 103 abuts against a portion of the housing of the second fan 13; wherein, the inner diameter of the air outlet duct 11 is greater than or equal to the outer diameter of the first air guide duct 14.

[0045] The detachable connection between the first air duct 14 and the second air inlet 103, as well as the threaded connection between the first air duct 14 and the outlet air duct 11, provides high installation flexibility and modularity. This means that this component can be easily disassembled and assembled in different application scenarios or for maintenance, facilitating adjustments to the duct layout according to site conditions or rapid component replacement, thus improving system adaptability and maintenance efficiency. The threaded connection, as a mature mechanical connection method, provides a reliable sealing effect, ensuring no airflow leakage between the first air duct 14 and the outlet air duct 11, helping to maintain the balance of air pressure inside and outside the equipment room. Simultaneously, the abutment design between the first air duct 14 and the housing of the second fan 13 ensures greater stability of the second fan 13 during operation, reducing vibration and noise, and preventing accidental displacement of the second fan 13.

[0046] Specifically, the air outlet assembly 10 further includes: a connector 15 disposed on the periphery of the air outlet cover 12, and a connecting groove 16 communicating with the second pipe opening on the peripheral wall of the air outlet duct 11, the connector 15 being rotatably connected to the connecting groove 16; and an elastic member 17, the air outlet cover 12 having a first connecting protrusion 18, and the inner peripheral wall of the air outlet duct 11 having a second connecting protrusion, the two ends of the elastic member 17 being connected to the first connecting protrusion 18 and the second connecting protrusion respectively, the elastic member 17 having a contracted state and a stretched state, when the elastic member 17 is in the contracted state, the air outlet cover 12 closes the second pipe opening, and when the elastic member 17 is in the stretched state, the air in the air outlet duct 11 impacts the air outlet cover 12 to open the second pipe opening. The connector 15 is a snap-fit ​​component, the connecting groove 16 is a snap-fit ​​groove, and the air outlet cover 12 forms a mechanical engagement with the air outlet duct 11 through the snap-fit ​​component thereon. The air outlet cover 12 can achieve a certain range of opening and closing movements with the fastener as the rotation center.

[0047] In this way, the elastic element 17 enables the air outlet cover 12 to automatically open and close according to the airflow conditions within the air outlet duct 11. When the system stops operating or the airflow is weak, the elastic element 17 returns to its contracted state, causing the air outlet cover 12 to close the second pipe opening, preventing external pollutants from entering the air conditioner or machine room, and maintaining a clean and stable internal environment. When the system starts up and the airflow within the air outlet duct 11 reaches a certain speed and pressure, the elastic element 17 is subjected to air impact and is in a stretched state, thereby automatically opening the air outlet cover 12, ensuring unobstructed airflow and improving the intelligence and automation of system operation.

[0048] This design makes opening and closing the air outlet cover 12 very easy, facilitating regular cleaning and inspection by maintenance personnel, reducing the accumulation of dust and impurities inside the air outlet duct 11, maintaining unobstructed airflow, and further improving the system's heat dissipation efficiency.

[0049] In this embodiment, the elastic element 17 is a spring.

[0050] In this embodiment, the cabinet air conditioner further includes an air intake assembly 20, which is disposed in the first air duct 7 and connected to the first air inlet 101. The air intake assembly 20 includes a filter element 21 for filtering the air flowing into the second air duct 8 from the second air inlet 103.

[0051] The aforementioned configuration allows filter 21 to effectively filter volatile organic compounds (VOCs), ozone, and other harmful gases from the air entering the first air duct 7 from the second air inlet 103, as well as dust, pollen, PM2.5, and other particulate matter from the outside air, preventing them from entering the computer room and maintaining indoor air cleanliness. This is crucial for protecting the high-precision equipment inside the computer room from dust and contaminants, reducing equipment maintenance frequency, and extending equipment lifespan. It also prevents equipment performance degradation or accidental damage, ensuring the stable operation of communication and data processing equipment. Furthermore, clean air reduces dust accumulation on the surfaces of the evaporator 3 and condenser 5, preventing a decrease in heat exchange efficiency and maintaining the efficient operation of the air conditioning system. This has a direct and positive impact on reducing energy consumption and maintenance costs, as well as improving the overall performance of the system.

[0052] Compared to existing traditional base station air conditioning systems, which mostly employ a closed-loop cooling mode and rely solely on return air for temperature and humidity regulation, lacking fresh air intake, leading to stagnant air, increased carbon dioxide concentration, unremoved harmful gases and odors, and dust accumulation, this application addresses the issue by introducing external cool air through the air intake component 20. This assists the air conditioning system in lowering the equipment room temperature and preventing equipment malfunctions due to overheating. It significantly reduces the air conditioning load during high summer temperatures or when equipment is under heavy load. Through the synergistic effect of the air intake component 20 and the air conditioning system, the humidity in the equipment room can be regulated to a suitable range (typically 40%-60%), preventing excessive humidity from causing equipment dampness and corrosion, or excessively low humidity from causing static electricity problems.

[0053] In this embodiment, the filter element 21 is an activated carbon filter.

[0054] Specifically, such as Figure 5 As shown, the air intake assembly 20 includes: an air intake duct 22 having a third port and a fourth port, the third port being connected to the first air intake 101 and the fourth port being connected to the first air duct 7; an air intake cover 23 and a third fan 24, the air intake cover 23 being movably connected to the fourth port for opening or closing the fourth port, and the third fan 24 and the filter element 21 being installed inside the air intake duct 22.

[0055] The movable connection between the air inlet cover 23 and the fourth duct allows the system to automatically or manually adjust the cover's position as needed, thereby precisely controlling the amount of air entering the first air duct 7. When fresh air is not needed, the air inlet cover 23 can close the fourth duct to prevent dust, moisture, or harmful substances from entering, protecting internal equipment from damage and reducing energy waste. The filter element 21 provides preliminary purification of the incoming air, effectively removing particulate matter, dust, pollen, and other impurities, maintaining the cleanliness of the air inside the first air duct 7.

[0056] The third fan 24, as the power source driving the airflow, can adjust its speed according to system requirements and intelligently control the ventilation volume. When the ambient temperature is suitable or the heat load inside the cabinet is low, the speed of the third fan 24 can be adjusted to introduce an appropriate amount of fresh air, thereby reducing the burden on the compressor and achieving energy-saving operation.

[0057] Specifically, a third positioning groove 220 is provided on the inner peripheral wall of the air inlet duct 22, and a third positioning protrusion 240 is provided on the outer peripheral wall of the third fan 24. The third positioning protrusion 240 is adapted to be connected to the third positioning groove 220. The third positioning groove 220 includes a first sub-groove and a second sub-groove that are perpendicularly connected to each other. One end of the first sub-groove is connected to the fourth pipe opening and extends along the axial direction of the air inlet duct 22. The third fan 24 has a locking state where it moves from the first sub-groove to the second sub-groove via the third positioning protrusion 240.

[0058] The mating connection between the third positioning protrusion 240 and the third positioning groove 220 ensures the stable positioning of the third fan 24 within the air inlet duct 22. This limits the displacement of the third fan 24 along and around its axial direction within the air inlet duct 22, preventing displacement due to vibration or airflow impact during operation and improving system stability and reliability. Installation of the third fan 24 is simple: just push it along the axial direction of the air inlet duct 22 until the third positioning protrusion 240 enters the first sub-groove and moves to the connection between the first and second sub-grooves. Then, rotate the third fan 24 to lock the third positioning protrusion 240 into the second sub-groove. No additional tools are required. Disassembly is the reverse process, greatly improving maintenance and repair efficiency.

[0059] Optionally, the third positioning protrusion 240 is disposed on the inner peripheral wall of the air inlet duct 22, and the third positioning groove 220 is disposed on the outer peripheral wall of the third fan 24.

[0060] It should be noted that in this embodiment, the number of the third positioning protrusion 240 and the third positioning groove 220 can be multiple, and can be selected accordingly according to the usage requirements and actual working conditions.

[0061] In this embodiment, the air intake assembly 20 further includes: a connecting component 25, at least a portion of which is disposed on the periphery of the air intake cover 23, and at least another portion of which is disposed on the outer peripheral wall of the air intake duct 22, so that the air intake cover 23 is rotatably connected to the air intake duct 22; and a stop block 26 disposed on the outer peripheral wall of the air intake duct 22. The air intake cover 23 has a closed state (closing the fourth pipe opening) and an open state (opening the fourth pipe opening). When the air intake cover 23 is in the open state and the opening of the fourth pipe opening is at its maximum, the air intake cover 23 contacts the stop block 26. The connecting component 25 includes a pin and a sleeve. The air intake cover 23 engages with the sleeve on the periphery of the air intake duct 22 via the pin, and the pin passes through the sleeve to achieve rotational constraint of the air intake cover 23. The air intake cover 23 can rotate and open within a range of 0-90° around the pin.

[0062] This allows the air inlet cover 23 to rotate relative to the air inlet duct 22, meaning the cover's position can be automatically or manually adjusted as needed to control airflow. This design can close the fourth duct opening when the air conditioning system is not running or in harsh environmental conditions, preventing external dust, rainwater, or other contaminants from entering the cabinet and protecting the internal equipment. The stop block 26 ensures the maximum opening of the air inlet cover 23. When the air inlet cover 23 rotates to 90°, the stop block 26 and the air inlet cover 23 form a mechanical stop, preventing over-opening. Therefore, the combined use of the connecting component 25 and the stop block 26 ensures that the air inlet cover 23 opens and closes under appropriate times and conditions, achieving intelligent environmental regulation and airflow control, which helps improve the automation level and operating efficiency of the air conditioning system.

[0063] Specifically, the air inlet assembly 20 further includes: a positioning element disposed on the inner peripheral wall of the air inlet duct 22, one end of the filter element 21 abutting against the positioning element; a second air guide duct 27, one end of which is detachably connected to the first air inlet 101, the other end of which has a second external thread section on its outer peripheral wall, and the air inlet duct 22 has a second internal thread section on its inner peripheral wall near the third inlet, so that after the second external thread section and the second internal thread section are connected, the end of the second air guide duct 27 away from the first air inlet 101 abuts against the other end of the filter element 21; wherein, the inner diameter of the air inlet duct 22 is greater than or equal to the outer diameter of the second air guide duct 27.

[0064] Optionally, the positioning element is an annular protrusion provided on the inner peripheral wall of the air inlet duct 22, or a fourth positioning protrusion provided at intervals on the inner peripheral wall of the air inlet duct 22.

[0065] The positioning element ensures that the filter element 21 can stably contact the inner wall of the air inlet duct 22 at one end. The threaded connection between the second air guide duct 27 and the air inlet duct 22 prevents displacement or vibration of the filter element 21 during operation, ensuring the continuity and reliability of the filtration effect. This stable positioning also facilitates the replacement or cleaning of the filter element 21, reducing maintenance workload. Furthermore, it allows for easy disassembly and assembly of the filter element 21 in different application scenarios or during maintenance, facilitating adjustments to the duct layout based on site conditions or rapid component replacement, improving system adaptability and maintenance efficiency. The threaded connection, as a mature mechanical connection method, provides a reliable seal, ensuring no airflow leakage between the second air guide duct 27 and the air inlet duct 22, helping to maintain the balance of air pressure inside and outside the equipment room. Simultaneously, the abutting design between the second air guide duct 27 and the filter element 21 ensures greater stability of the filter element 21 during operation, reducing vibration and noise, and preventing accidental displacement of the filter element 21.

[0066] In this embodiment, the casing 1 consists of a front door panel, two side panels, a rear door panel, a top cover, and a chassis component, all of which are connected and fixed by fasteners. A third air inlet 105 is located on the upper part of the left and right side panels near the rear door panel, and two condensers 5 are installed on the left and right side panels at positions corresponding to the third air inlet 105. The side panels of the condensers 5 have pre-drilled screw holes and are fixed to the side panels with fasteners. The bottom of the condensers 5 is a partition 2, and the partition 2 is connected to the rear door panel, side panels, and top cover respectively through sheet metal folding structures, with the connections secured by screws. The partition 2 divides the interior of the entire frame into two air ducts, namely the first air duct 7 and the second air duct 8.

[0067] In this application, the control logic of the rack air conditioner is as follows:

[0068] When the indoor temperature exceeds the first preset threshold, the system controls the compressor to shut down and starts the third fan 24. Outside cold air enters from the first air inlet 101 and passes through a coarse filter to preliminarily purify the outdoor cold air. The airflow then rushes through the air inlet cover 23 and enters the first air duct 7. It then passes through the evaporator 3 and the first fan 4 and enters the base station from the first air outlet 102 to form an airflow channel. Simultaneously, the second fan 13 starts to discharge the hot air inside the base station to the outside through the air outlet 11 from the second air outlet 104, so that the air pressure inside and outside the base station is kept consistent. On the other hand, it reduces the compressor's working time and increases the compressor's service life.

[0069] When the indoor humidity exceeds the second preset threshold, the system controls the shutdown of the third fan 24 to cut off the introduction of external air and prevent moisture from entering the room further; it activates the condenser 5, compressor and fourth fan 6 to start the cabinet cooling cycle system and enter the dehumidification mode to reduce the indoor air humidity through the condensation dehumidification mechanism.

[0070] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0071] By installing a partition 2 inside the casing 1, the space is effectively divided into a first air duct 7 and a second air duct 8, achieving zoned management of internal airflow. The first air duct 7 introduces cool outdoor air through the first air inlet 101, which is cooled by the evaporator 3 and then sent into the room through the first air outlet 102 for heat exchange, thus achieving efficient heat dissipation for indoor equipment. This zoned heat dissipation method avoids the potential temperature fluctuations or direct introduction of pollutants that might result from directly sending outdoor air into the room, improving heat dissipation efficiency and environmental purification capabilities. The second air inlet 103 and the second air outlet 104, connected to the air outlet assembly 10, allow hot indoor air to flow directly from the second air inlet 103 through the second air outlet 104 to the outside, accelerating air circulation and exchange. This mechanism helps balance the air pressure inside and outside the computer room, reducing structural risks caused by pressure differences, while also improving indoor air quality, reducing carbon dioxide concentration and harmful gas content, and providing a healthier environment for equipment and maintenance personnel. This solves the problem in existing rack air conditioners where balancing indoor and outdoor air pressure during air exchange is difficult, leading to increased air conditioning load and energy consumption. Furthermore, under suitable environmental conditions, such as when the outside temperature is low, natural cool air can be introduced through the first air inlet 101, thereby reducing the compressor's start-up and running time. The compressor and other equipment do not need to operate under high load for extended periods, and may even be shut down, extending their service life, reducing maintenance frequency, and thus lowering the overall energy consumption of the air conditioning system. At the same time, the optimized air circulation system reduces the risk of equipment overheating, helping to extend equipment life and reduce long-term operating and maintenance costs.
