Description
Technical Field
[0001] This utility model relates to the technical field of liquid-cooled temperature control equipment, specifically to an ultra-thin air conditioning unit with a wind wall. Background Technology
[0002] The control of temperature and humidity in data center computer rooms relies on indoor air conditioning terminals. Computer room air conditioners are characterized by high efficiency, high sensible heat ratio, high reliability and flexibility, and can meet the increasing requirements of data center computer rooms for server heat dissipation, constant humidity control, air filtration and other aspects.
[0003] With increasingly stringent PUE requirements across different regions and the widespread application of high-density servers, new cooling methods for data centers are being developed and utilized. Airwalls, as one energy-saving airflow organization method, are being adopted by more and more HVAC designers. Airwall air conditioners achieve temperature control through airflow circulation and fresh air introduction, primarily used in environments requiring efficient heat dissipation, such as data centers. Their core working principle can be summarized into two modes: internal circulation mode and enclosed natural cooling mode. Furthermore, some airwall air conditioners borrow the "fresh air flow field" principle from wall-mounted fresh air systems, forming a stable airflow path through directional air supply and exhaust to ensure air exchange efficiency. Their control logic includes fan speed regulation and cooling water flow control. This type of air conditioner is particularly suitable for high-heat-load scenarios such as data centers, enhancing airflow uniformity and reducing PUE (Power Usage Effectiveness) through a matrix fan layout.
[0004] Existing wall-mounted air conditioning units have low internal space utilization. The fan and filter components are all housed inside the wall casing, requiring the entire casing to be removed for replacement or repair. This bulky size prevents quick, modular installation in confined spaces. Therefore, a wall-mounted air conditioning system suitable for small spaces is needed, along with improved installation methods for the fan and filter components to facilitate future maintenance.

[0023] The technical solutions of the present utility model will now be described with reference to the accompanying drawings in the embodiments of the present utility model:
[0024] Existing wall-mounted air conditioning units require individual installation of numerous fans, hindering rapid on-site installation and resulting in prolonged production time. Furthermore, the control box is inconveniently located, requiring tools for operation, leading to complex, time-consuming, and costly maintenance. To address these issues, this invention provides an ultra-thin wall-mounted air conditioning unit, comprising a wall-mounted cabinet 1. The cabinet 1 includes a front sealing plate 11, a rear sealing plate 12, a left-side mounting plate 13, and a right-side mounting plate 14. The cabinet 1 houses a condenser coil 4, a water supply pipe 6, and a return water pipe 7. The water supply pipe 6 and return water pipe 7 are connected to the outlet and inlet of the condenser coil 4, respectively. The condenser coil 4 contains stainless steel piping for heat exchange with the airflow and chilled water absorption. It absorbs heat to achieve heat absorption and cooling; both the front sealing plate 11 and the rear sealing plate 12 can be detachably connected to the air wall cabinet 1 to block the forklift hole and prevent air leakage; the front of the air wall cabinet 1 is equipped with several fan mounting plates 15 and an electrical control box 2. The electrical control box 2 is located between the several fan mounting plates 15 and is 1.5m to 1.6m above the ground for easy manual operation; the electrical control box 2 includes a left electrical control box door 21 and a right electrical control box door 22; the right electrical control box door 22 is equipped with a touch screen 23. Multiple fans 3 are mounted on the fan mounting plate 15; generally, there are no fewer than five fans on the fan mounting plate 15, and no fewer than three fans 3 are mounted on each fan mounting plate 15. Handles 16 are provided on both sides of the fan mounting plate 15, with multiple fans 3 located between the handles 16 on both sides. The handles 16 allow for quick and easy disassembly of the entire unit to drive airflow circulation. For maintenance, individual fan mounting plates 15 can be removed. A filter device 5 is located at the rear of the air wall cabinet 1. The filter device 5 includes a filter element mounting frame 51 and a filter element 52. Clips 54 are installed on the filter element mounting frame 51 to fix the filter element 52. Additionally, a temperature and humidity sensor 53 is installed on the rear side of the filter element 52. The filter element 52 is used to filter air impurities, such as… Figure 7 , Figure 8As shown, the four corners of the filter element 52 are detachably connected to the filter element mounting frame 51 by buckles 54. One end of the buckle 54 is a locking buckle 541 and the other end is a pin 542. The filter element mounting frame 51 is provided with a buckle groove 55 that engages with the buckle 54. The pin 542 is rotatably connected to one side of the filter element mounting frame 51. The front end of the locking buckle 541 engages with the buckle groove 55 located on the other side of the filter element mounting frame 51. The middle part of the buckle 54 holds the filter element 52 in place. During installation, after placing the filter element 52 in place, rotate the four corner clips 54 in sequence to engage the other end of the clip 54 into the clip groove 55. The locking buckle 541 prevents the clip 54 from coming out of the clip groove 55. The filter element 52 is fixed by the four corners of the clips 54. The filter element 52 can be replaced by manually rotating the clips 54. The water supply pipeline 6 also includes a second temperature and humidity sensor 61, a first pressure sensor 62, and a water supply pipeline inlet 63. The return water pipeline 7 also includes a temperature sensor 71, a second pressure sensor 72, and a return water pipeline outlet 74. The second pressure sensor 72 is equipped with an electric two-way valve 73 at its rear end. The electric two-way valve 73 adjusts the water flow intelligently to control the cooling capacity based on the data from the first temperature and humidity sensor 53, the second temperature and humidity sensor 61, and the temperature sensor 71, thus avoiding overcooling. The water supply pipeline inlet 63 and the return water pipeline outlet 74 are both located at the bottom of the air wall cabinet 1. The water supply pipeline 6 and return pipeline 7 are centrally arranged to support quick connection when multiple units are connected in parallel, reducing energy consumption at pipeline bends.
[0025] As shown in the figure, the embodiment of this utility model includes a fan wall cabinet 1. The four sides of the fan wall cabinet 1 are a front sealing plate 11, a rear sealing plate 12, a left side mounting plate 13, and a right side mounting plate 14. The front sealing plate 11 and the rear sealing plate 12 are removable and cover the forklift hole to prevent air leakage. Seven fan mounting plates 15 are installed at the front of the unit, and four fans 3 are installed on the fan mounting plates 15. The fan 3 model is EC-20572-22BU1-026. The handle 16 is located at the end of the fan mounting plate 15, avoiding the fan 3. Each fan mounting plate 15 is equipped with wiring. Junction boxes 17 are responsible for wiring the four fans 3 on each fan mounting plate 15, which facilitates installation and wiring and is also beneficial for later maintenance. The seven junction boxes 17 then connect the lines to the electrical control box 2 for control. The electrical control box 2 includes a left electrical control box door 21 and a right electrical control box door 22. The right electrical control box door 22 is equipped with a touch screen 23, which is connected to the right electrical control box door 22 by a cylindrical lock 24. The left electrical control box door 21 and the right electrical control box door 22 are both connected to the fan wall cabinet 1 by hinges 25. The outlet of the condenser coil 4 is connected to the water supply pipe 6, and the inlet is connected to the return water pipe 7. The filter device 5 includes a filter element mounting frame 51 and a filter element 52. The filter element mounting frame 51 is grid-shaped, and each grid is fitted with a filter element 52. The temperature and humidity sensor 53 detects the hot air temperature in the machine room. The air wall air conditioning unit has a size of only 400mm*1200mm*2000mm, which has a high space utilization rate and is suitable for setting up the unit in a small space.
[0026] A wind-wall air conditioner is a type of air conditioner suitable for large public places. It mainly uses a continuous air circulation method, drawing air in from one side, cooling it through heat exchange, and then exhausting it from the other side, thus forming an air curtain similar to a wall to keep the indoor air comfortable.
[0027] During operation, fan 3 draws air from the machine room. The air is first purified by filter 52, then passes through condenser coil 4 and is discharged from fan 3. The refrigerant absorbs heat from the room during evaporation and then dissipates it outdoors, creating a cooling effect. The refrigerant enters from the bottom return water pipe outlet 74, and its flow is regulated by temperature sensor 71, pressure sensor 72, and electric two-way valve 73 (model TBG50-2LBC-BX+TW10NM-XA24) before entering condenser coil 4. Temperature sensor 71 has a B value of 3950 and a resistance of 10K. The refrigerant in condenser coil 4 is discharged through water supply pipe 6, passing through temperature and humidity sensor 61, pressure sensor 62, and water supply pipe inlet 63. Touch screen 23 displays real-time temperature / pressure data and automatically adjusts fan speed and water valve opening. Pressure sensor 1 (62) and pressure sensor 2 (72) are model number 35CP11-06162010XS00H1HC-ENV; temperature and humidity sensor 1 (53) and temperature and humidity sensor 2 (61) are model number SLP180.
[0028] This utility model features several independently detachable fan mounting plates 15 on one side, each mounting multiple fans 3; a filter element 52 is snap-fitted to the other side, and a water supply pipe 6 and a return water pipe 7 are centrally located at the bottom, breaking through the size limitations of traditional airflow wall equipment. During operation, the fans 3 drive the airflow through the filter element 52 for purification, and then exchange heat with the condenser coil 4, forming a directional airflow wall. Cooling water circulates through the bottom water supply pipe 6 and return water pipe 7, with flow and temperature controlled by a second temperature and humidity sensor 61, a first pressure sensor 62, a temperature sensor 71, a second pressure sensor 72, and an electric two-way valve 73. The modular architecture of the equipment accelerates the entire "production-installation-maintenance" process, meeting the high-density heat dissipation and rapid deployment requirements of data centers.
[0029] The above embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
