[0052] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. It is worth noting that the embodiments described in the accompanying drawings are only some embodiments of this application, and not all embodiments. That is, the embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0053] The following will combine Figures 1-5 The ultra-thin large-space air conditioning unit provided in the embodiments of this application will be described.

[0054] This application provides an ultra-thin, large-space air conditioning unit 100, such as... Figures 1-5 As shown, it includes a housing 110, a return air inlet, a fan 120, a heat exchanger 130, an air supply hood 140, and a spherical nozzle 150.

[0055] The casing 110 includes a bottom plate 111, a top plate 112, a front side plate 113, a rear side plate 114, a left side plate 115 and a right side plate 116, and the length of the casing 110 in the left-right direction is greater than the width in the front-rear direction, and the width of the casing 110 in the front-rear direction is greater than the height in the up-down direction.

[0056] The air return opening is arranged at the rear side of the bottom plate 111, extends in the left-right direction, and is provided with a filter screen 1113.

[0057] The fan 120 is arranged in the casing 110 close to the air return opening, the suction port of the fan 120 is communicated with the air return opening, and the discharge port of the fan 120 faces the front side plate 113.

[0058] The partition plate 121 is tightly attached to the discharge port of the fan 120, the partition plate 121 is provided with a through hole communicated with the discharge port of the fan 120, and the partition plate 121 is arranged parallel to the front side plate 113, and the periphery of the partition plate 121 is tightly connected with the inner side of the casing 110.

[0059] The heat exchanger 130 is arranged between the partition plate 121 and the front side plate 113 in the casing 110, and extends in the left-right direction.

[0060] The air supply cover 140 is connected to the front side plate 113, the front side plate 113 is provided with an air supply hole, and the air supply cover 140 is arranged around the air supply hole.

[0061] The spherical nozzle 150 is arranged on the air supply cover 140.

[0062] The casing 110 is connected by the bottom plate 111, the top plate 112, the front side plate 113, the rear side plate 114, the left side plate 115 and the right side plate 116 to form a rectangular casing. During installation, the long side of the rectangular casing is parallel to the wall of the building, the air return opening is located on the bottom side close to the wall, and the filter screen 1113 of the air return opening filters the return air to make clean return air enter the casing for heat exchange and air supply. The fan 120 can adopt an outer rotor centrifugal fan, the base of the fan 120 is fixedly connected to the bottom plate 111, the inlet on the side of the fan 120 is communicated with the air return opening on the bottom plate 111, and the discharge port on the upper part of the fan 120 is communicated with the partition plate 121. The optional model of the fan 120 includes 225M, which has undergone strict static balance, dynamic balance and whole machine dynamic balance inspection, to ensure that the whole machine has low running noise, high efficiency and stable performance.

[0063] The partition plate 121 can be screwed to the outlet periphery of the fan 120. The partition plate 121 can be provided with a folded edge, which is tightly connected to the inner side of the casing 110. The partition plate 121 separates the fan 120 and the heat exchanger 130 on both sides, so that the inlet of the fan 120 is communicated with the return air outlet on the bottom plate 111, and the heat exchanger 130 forms a static pressure air tank on one side. The heat exchanger 130 can be connected by seamless steel pipes and aluminum fin expansion pipes, which has the advantages of high heat exchange efficiency and low flow resistance. The water inlet pipe and the water outlet pipe of the heat exchanger 130 can be arranged on the left side plate 113 or the right side plate 114, which is convenient for disassembly and maintenance. The lower part of the heat exchanger 130 in the casing 110 is provided with a water pan 131, which has an inclination angle to facilitate the smooth discharge of condensed water, and prevents direct flow of sewage and bacterial growth.

[0064] The front side plate 113 is provided with an air supply hole, and an air supply cover 140 is arranged on the air supply hole. The space of the air supply cover 140 is relatively small compared with the space of the casing where the heat exchanger 130 is arranged, which is beneficial to increase the air pressure and improve the range. The spherical nozzle 150 on the air supply cover 140 is a product of the prior art, and the optional models include 250Q, 300Q, 315Q, 350Q, 400Q or 450Q. The spherical nozzle 150 has a shape of gradually reducing in diameter along the air supply direction, which can increase the air pressure, improve the range, and is beneficial to air supply to a farther distance.

[0065] The embodiment of the present application provides an ultra-thin large-space air conditioning unit 100, which comprises a casing 110, a return air outlet, a fan 120, a heat exchanger 130, an air supply cover 140 and a spherical nozzle 150. The return air outlet is arranged on the rear side of the bottom plate 111, and the air supply cover 140 is arranged on the air supply hole of the front side plate 113. After the return air is introduced from the bottom surface by the fan 120, the heat exchange is performed on the heat exchanger 130 on the other side of the partition plate 121, and the air after heat exchange is sprayed from the spherical nozzle 150 of the air supply cover 140 to supply air to the ground. In this way, the air flows and exchanges heat in the casing 110 basically along the horizontal direction, thereby the height of the casing 110 can be greatly reduced; on the other hand, the air is introduced from the bottom surface, avoiding the need to consider the return air space and disassembly space between the return air outlet arranged on the side and the building wall, so that the position of the building wall does not need to be considered, and the air conditioning unit 100 can be directly installed against the wall, improving the flexibility of installation. The spherical nozzle 150 is a product of the prior art, and the air supply angle can be adjusted. The air after heat exchange forms a static pressure air tank on the side of the partition plate 121 and the air supply cover 140, and maintains a certain static pressure. Then, the spherical nozzle 150 has a shape of gradually reducing in diameter along the air supply direction, which can increase the air pressure, improve the range, and has the advantage of farther air supply distance. Based on this, the ultra-thin large-space air conditioning unit 100 of the embodiment of the present application can be suitable for the temperature regulation demand of a building space with a relatively low height and a relatively large span by virtue of a smaller equipment height, a larger air volume and air pressure, and is especially suitable for a height space of 6 meters or less.

[0066] In an implementable embodiment, asFigure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the side of the air supply hood 140 away from the air supply hole is set with an incline. The upper side of the incline is inclined away from the front side plate 113, and the lower side is inclined towards the front side plate 113.

[0067] Thus, the spherical nozzle 150 is installed on the front side of the housing 110 with the air delivery surface tilted downwards. On one hand, although the air delivery direction of the spherical nozzle 150 is adjustable, the adjustable angle is limited. The side of the air delivery shroud 140 away from the air delivery hole is designed as a slope, which facilitates the installation of the spherical nozzle 150 and makes it easier to adjust the airflow from the spherical nozzle 150 to the ground. On the other hand, the overall space of the air delivery shroud 140 is relatively smaller than that of the rectangular housing, which, together with the spherical air delivery nozzle, forms a space with a gradually decreasing diameter, further increasing the air pressure and improving the range.

[0068] In one feasible implementation, the angle between the inclined surface of the air supply hood 140 and the horizontal plane is in the range of 70°-80°.

[0069] This makes it easier to coordinate with the structure of the spherical nozzle 150 itself, adjust the angle at which the air is blown to the ground, and increase the wind pressure and range.

[0070] In one feasible implementation, such as Figure 5 As shown, the air supply hood 140 includes two side plates 141 arranged on the left and right, and an integrally bent hood 142 connecting the top, front and bottom surfaces of the two side plates 141.

[0071] A chamfer is provided between the top surface and the front side of the side panel 141, and a guide surface 1421 corresponding to the chamfer is provided on the hood 142 to prevent sharp corners.

[0072] This design facilitates the formation of a slope, making installation easier and increasing wind pressure. It also helps prevent sharp corners, avoiding the problem of dead air pressure inside and potential injury to workers outside.

[0073] In one feasible implementation, such as Figure 4 and Figure 5 As shown, the base plate 111 has upward folded edges 1111 on both the front and rear sides, and double upward folded edges 1112 on both the left and right sides, which fold upward and then inward and upward. The top plate 112 has downward folded edges 1121 on both the front and rear sides, and double downward folded edges 1122 on both the left and right sides, which fold downward and then inward and downward.

[0074] The left and right sides of the front side plate 113 are provided with double rear flanges 1131 which are folded back first and then folded back inwardly.

[0075] The front side plate 113 is located inside the upper flange 1111 on the front side of the bottom plate 111 and inside the lower flange 1121 on the front side of the top plate 112, and is connected to the corresponding upper flange 1111, double upper flange 1112, lower flange 1121 and double lower flange 1122.

[0076] The rear side plate 114 is located inside the upper flange 1111 on the rear side of the bottom plate 111 and inside the lower flange 1121 on the rear side of the top plate 112, and is connected to the corresponding upper flange 1111, double upper flange 1112, lower flange 1121 and double lower flange 1122.

[0077] The left and right side plates 113 and 114 are connected to the corresponding double upper flanges 1112, double lower flanges 1122, double front flanges 1141 and double rear flanges 1131 on the corresponding sides.

[0078] The components of the casing 110 can be connected by screws. In order to avoid interference between each other, the corresponding overlapping positions of the upper flange 1111, double upper flange 1112, lower flange 1121 and double lower flange 1122 can be appropriately shortened. For example, after the double upper flanges 1112 on the left and right sides of the bottom plate 111 are folded upward, the two ends can be simultaneously shortened in the front-rear direction, and then folded inwardly and upwardly. Correspondingly, after the double lower flanges 1122 on the left and right sides of the top plate 112 are folded downward, the two ends can be simultaneously shortened in the front-rear direction, and then folded inwardly and upwardly. And the double rear flanges 1131 and double front flanges 1141 of the corresponding front side plate 113 and rear side plate 114 are also folded twice after the corresponding first folding, the two ends are simultaneously shortened in the up-down direction, and the second folding is performed between the double upper flanges 1112 and the double lower flanges 1122.

[0079] In this way, the bottom plate 111 supports the front side plate 113 and the rear side plate 114, the top plate 112 covers the front side plate 113 and the rear side plate 114, and the left and right side plates 115 and 116 are mounted on the flanges of the top plate 112, the bottom plate 111, the front side plate 113 and the rear side plate 114, which facilitates quick assembly and disassembly of the left and right side plates 115 and 116; and further facilitates disassembly of the top plate 112, the left and right side plates 115 and 116, and maintenance work such as repair of temperature sensors, fans 120, and welding positions of water inlet and outlet pipes on both sides of the heat exchanger 130.

[0080] In an implementation that can be realized, as Figure 2 and Figure 3As shown, the base plate 111 is provided with a double inner folded edge that folds upward and towards the center at the return air vent, and the filter screen 1113 is connected to the double inner folded edge.

[0081] This makes it easy to disassemble and replace the filter 1113, ensuring that the return air is always kept clean.

[0082] In one feasible implementation, such as Figures 1-5 As shown, lifting beams 117 are welded to the lower surface of the base plate 111 at the corresponding left and right edge positions. The lifting beams 117 extend in the front-back direction and both ends extend out of the outer side of the base plate 111. Lifting holes are opened at the positions where the lifting beams 117 extend out of the outer side of the base plate 111.

[0083] Alternatively, lifting beams 117 are welded to the corners on both sides of the base plate 111. The lifting beams 117 extend in the front-to-back direction and each lifting beam 117 has a lifting hole.

[0084] In this way, the lifting beam is installed on the left and right edges of the base plate 111, which not only facilitates hoisting, but also has little impact on the disassembly and assembly of the left side plate 115 and right side plate 116, water inlet pipe, water outlet pipe and the electrical control box 160 described below.

[0085] In one feasible implementation, the length of the housing 110 ranges from 900mm to 2100mm, the width of the housing 110 ranges from 970mm to 1250mm, and the height of the housing 110 ranges from 520mm to 750mm.

[0086] This effectively shortens the height of the casing 110, making it suitable for temperature regulation needs in building spaces with relatively low heights but relatively large spans, especially for spaces with a height of less than 6 meters.

[0087] In one possible implementation, the housing 110 includes a sheet metal part with an insulation layer attached to the inside of the sheet metal part.

[0088] Alternatively, the housing 110 may include an inner metal panel and an outer metal panel, with a polyurethane insulation layer injected between the inner and outer metal panels.

[0089] In this way, the casing 110 can be manufactured using sheet metal processing or by injecting an insulation layer. The insulation layer improves the insulation and soundproofing of the casing 110, and also provides fire resistance, high strength, long service life, and good cleanability.

[0090] In one feasible implementation, the ultra-thin large-space air conditioning unit 100 also includes an electronic controller and temperature sensors, including a return air temperature sensor and a supply air temperature sensor. The electronic controller is electrically connected to the fan 120, the return air temperature sensor, the control terminal of the spherical nozzle 150, and the supply air temperature sensor.

[0091] Wherein, the electric controller can control the air volume and air speed of the fan 120 and the spherical nozzle 150 according to the temperature of the return air and the supply air detected by the temperature sensor, to realize automatic control. Specifically, an electric control box 160 can be installed on the side of the casing 110 opposite to the inlet pipe and the outlet pipe of the heat exchanger 130, the electric controller is installed in the electric control box 160, and a wireless remote controller is arranged on the ground and is wirelessly connected to the electric controller.
