Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a curtain wall air conditioner. Background Art

[0002] In modern life, air conditioners have become an indispensable household appliance, providing people with a comfortable indoor temperature environment. As an important part of the air conditioning system, the performance and maintainability of curtain wall air conditioners directly affect the use effect and life of air conditioners.

[0003] There is a significant problem in the design of the common curtain wall air conditioners on the market, that is, the installation method of the fan in the indoor unit is not reasonable enough. During the long-term use of the air conditioner, the fan may fail due to long-term operation, wear and tear, and various unforeseen factors. However, most curtain wall air conditioners use centrifugal fans, which are connected to the housing through multiple complex connectors. Generally speaking, the volute of the centrifugal fan is fixedly connected to the housing or the partition plate in the housing, and it is not easy to disassemble it. Therefore, the impeller of the centrifugal fan needs to be removed from the volute during maintenance. Since the impeller is axially connected to the motor, not only do you need to remove many screws, buckles and other fixings, but the space at the installation location of the curtain wall air conditioner is narrow, especially the axial operation space is limited, and the impeller is not easy to be removed from the volute in the axial direction, which makes it difficult to disassemble the fan and is very time-consuming and laborious.

[0004] This inconvenience in removing the fan has caused great trouble to users and maintenance personnel in actual maintenance. Users may need to wait for a long time to complete the maintenance, affecting normal use; maintenance personnel need to spend more energy and time to solve this problem, increasing maintenance costs. In summary, the problem that the fan in the existing curtain wall air conditioner is not easy to remove from the shell has seriously affected the maintenance convenience and efficiency of the air conditioner, and has become a technical problem that needs to be solved urgently.

[0042] The details of the present invention can be more clearly understood by combining the accompanying drawings with the description of the specific embodiments of the present invention. However, the specific embodiments of the present invention described herein are only used for the purpose of explaining the present invention and cannot be understood as limiting the present invention in any way. Under the guidance of the present invention, technicians can conceive of any possible variations based on the present invention, which should be considered to belong to the scope of the present invention.

[0043] In order to solve the problem that the fan 4 is difficult to maintain in the prior art, a curtain wall air conditioner is proposed in this application. Figure 1 This is a schematic diagram of the structure of the curtain wall air conditioner in the embodiment of the utility model. Figure 3 This is a cross-sectional view of a curtain wall air conditioner in an embodiment of the utility model in one implementation manner. Figure 4 FIG. 2 is a cross-sectional view of a curtain wall air conditioner in another embodiment of the present utility model. Figure 1 , Figure 3 and Figure 4 As shown, the curtain wall air conditioner may include: a shell 1, wherein the shell 1 has a first partition mechanism 2 to divide the shell 1 into a first space 13 and a second space 14 distributed in a horizontal direction, and the shell 1 corresponding to the first space 13 has an air outlet 11; a heat exchange unit 3, which is arranged in the first space 13; a fan 4, which is a cross-flow fan, and the cross-flow fan is arranged in the second space 14, and the shell 1 corresponding to the second space 14 has a notch 12 on the side opposite to the first space 13, and the cross-flow fan can be taken out through the notch 12, and the gas flowing in from the notch 12 flows through the heat exchange unit 3 after passing through the cross-flow fan and is output from the air outlet 11.

[0044] The curtain wall air conditioner in the present application uses a cross-flow fan as the fan 4, which has the characteristics of compact structure and small size. The cross-flow fan is arranged in the second space 14 and the housing 1 corresponding to the second space 14 has a notch 12 on the side opposite to the first space 13. In this way, when the cross-flow fan needs to be repaired, the entire cross-flow fan can be directly, quickly and conveniently taken out from the notch 12 for repair, and then installed from the notch 12 to the second space 14. The above-mentioned whole process greatly reduces the difficulty of maintenance for maintenance personnel and effectively improves the maintenance speed.

[0045] In order to better understand the curtain wall air conditioner in this application, it will be further explained and illustrated below. Figure 1 , Figure 3 and Figure 4 As shown, the shell 1 may have an inner cavity for accommodating components such as a heat exchange unit 3 and a fan 4. The shell 1 has a first partitioning mechanism 2 to divide the shell 1 into a first space 13 and a second space 14 distributed in a horizontal direction, and the shell 1 corresponding to the first space 13 has an air outlet 11. The first partitioning mechanism 2 extends along the length direction of the curtain wall air conditioner. The shell 1 may have a top wall, a bottom wall, two end walls and a front wall arranged opposite to each other. The front wall is the wall surface corresponding to the first space 13. The shell 1 corresponding to the second space 14 has a notch 12 on the side opposite to the first space 13. The shell 1 may not have a rear wall, so that a notch 12 is directly formed on this side of the shell 1. In other feasible embodiments, the shell 1 may have a rear wall, and the notch 12 is located on the rear wall.

[0046] The fan 4 may be a cross-flow fan, which is arranged in the second space 14. The cross-flow fan has the advantages of compact structure and small size, and the radial dimension of the cross-flow fan is small, so it can be easily installed in the second space 14. Therefore, the cross-flow fan can be taken out or installed in the second space 14 through the notch 12. Since the cross-flow fan is arranged in the second space 14 and the housing 1 corresponding to the second space 14 has a notch 12 on the side opposite to the first space 13, when the cross-flow fan needs to be repaired, the entire cross-flow fan can be directly, quickly and conveniently taken out from the notch 12 for repair, and then installed in the second space 14 from the notch 12.

[0047] The number of crossflow fans can be one, two or more, and can be specifically set according to the length and requirements of the curtain wall air conditioner. When the number of crossflow fans is more than one, the crossflow fans are distributed along the length direction of the curtain wall air conditioner.

[0048] like Figure 3 and Figure 4 As shown, the heat exchange unit 3 is arranged in the first space 13. The heat exchange unit 3 may include heat exchange tubes, which are arranged in parallel with gaps between each other to ensure that the gas flows between the heat exchange tubes, so that the gas exchanges heat with the heat exchange medium flowing through the heat exchange tubes to achieve temperature regulation of the gas. The heat exchange medium can be a refrigerant, water, or other types of heat exchange fluids, which are not limited in the present application. Under the action of the cross-flow fan, the gas flowing in from the gap 12 passes through the cross-flow fan and then flows through the heat exchange unit 3 and is output from the air outlet 11.

[0049] As feasible, Figure 3 and Figure 4 As shown, the shell 1 and the first partition mechanism 2 corresponding to the first space 13 may have a heat preservation structure, so that condensation water on the shell 1 and the first partition mechanism 2 can be prevented from dripping onto the ground or ceiling. Further, the heat preservation structure is arranged on the inner wall of the shell 1.

[0050] In a possible implementation, Figure 3 As shown, the heat exchange tubes are arranged in a rectangular shape, and the heat exchange unit 3 can be arranged at an angle relative to the horizontal plane, with the side where the gas flows out of the heat exchange unit 3 facing the air outlet 11. In another feasible embodiment, as Figure 4As shown, the heat exchange tubes are distributed in a parallelogram shape, the heat exchange unit 3 is arranged parallel to the horizontal plane, and the side of the heat exchange unit 3 where the gas flows out faces the air outlet 11. In the above manner, multiple heat exchange tubes can be arranged in the vertical direction under the condition that the adjacent heat exchange tubes maintain the same distance, thereby improving the heat exchange efficiency between the gas and the heat exchange tubes. In the above two embodiments, correspondingly, the fixing plate for fixing the heat exchange tube can be rectangular or parallelogram, and the heat exchange tube passes through the fixing plate to achieve fixed limit.

[0051] As feasible, Figure 1 As shown, the crossflow fan may include an impeller, an air duct assembly and a motor for driving the impeller to rotate, and the motor, the air duct assembly and the impeller adopt an integrated structure. Through this structure, when the crossflow fan needs to be repaired, the entire crossflow fan can be directly taken out from the gap 12 for repair, without disassembling the crossflow fan and then taking out the broken parts, which can greatly improve the repair speed. Furthermore, the crossflow fan is connected to the housing 1 or the partition mechanism through a detachable fixing. The fixing can generally be a screw. When the crossflow fan needs to be repaired, it only needs to remove the fixing, and the crossflow fan can be taken out from the gap 12 for repair.

[0052] The first partitioning mechanism 2 has a connecting port connecting the first space 13 and the second space 14. When the crossflow fan is installed on the housing 1 or the partitioning mechanism, the outlet of the crossflow fan and the connecting port are matched together, so that the blown gas is input into the first space 13 through the connecting port and flows through the heat exchange unit 3. The number of the connecting ports can correspond to the number of the crossflow fans.

[0053] As feasible, Figure 3 and Figure 4 As shown, the air outlet 11 can be located on the bottom wall of the housing 1 and face downward. In this way, the curtain wall air conditioner can discharge air downward. As a feasible embodiment, the air outlet 11 can be located on the front wall of the housing 1 and face forward. In this way, the curtain wall air conditioner can discharge air forward. In other feasible embodiments, there can be two air outlets 11, one located on the bottom wall of the housing 1 and facing downward, and the other located on the front wall of the housing 1 and facing forward.

[0054] As feasible, Figure 5 Schematic diagram of a curtain wall air conditioner with a notch in the embodiment of the utility model. Figure 5As shown, the first space 13 is divided into a first space first part 131 and a first space second part 132 distributed in the horizontal direction by the second partition mechanism. The distribution direction of the first space first part 131 and the first space second part 132 is perpendicular to the distribution direction of the first space 13 and the second space 14. That is, the distribution direction of the first space first part 131 and the first space second part 132 is the length direction of the curtain wall air conditioner. The heat exchange unit 3 is arranged in the first space first part 131.

[0055] like Figure 2 and Figure 5 As shown, the curtain wall air conditioner may include: at least one valve assembly 5 arranged in the second part 132 of the first space, and the valve assembly 5 is connected to the heat exchange unit 3. The valve assembly 5 is used to control whether the heat exchange medium flows into the heat exchange unit 3 of the curtain wall air conditioner. For example, the valve assembly 5 may include an electric valve connected to the upstream of the heat exchange unit 3, and the valve assembly 5 may also include a stop valve connected to the downstream of the heat exchange unit 3. The first partition mechanism 2 corresponding to the second part 132 of the first space has an inspection port 21. When the valve assembly 5 fails or other components in the second part 132 of the first space fail, maintenance personnel can directly pass through the gap 12 and then through the inspection port 21 to repair or replace the components in the second part 132 of the first space. Further, the position corresponding to the inspection port 21 in the second space 14 is in an empty state, so that it is convenient for the maintenance personnel to extend their hands into the inspection port 21 through this position.

[0056] In order to prevent dust and the like from entering the second part 132 of the first space, an access panel that closes the access panel 21 may be provided at the access opening 21. When maintenance is required, the access panel can be removed. In order to facilitate the removal of the access panel, it is feasible that the access panel and the first partition mechanism 2 can be connected in a magnetic or snap-fit ​​manner, so that the access panel can be fixed without screws.

[0057] As feasible, Figure 6 FIG. 1 is an exploded view of the curtain wall air conditioner in the second part of the first space in an embodiment of the utility model. Figure 2 and Figure 6As shown, the curtain wall air conditioner may include: a sheet metal part 6 disposed in the second part 132 of the first space and fixedly connected to the shell 1 or the first partition mechanism 2. The sheet metal part 6 has a non-circular mounting port 61. The shell 1 of the valve assembly 5 has a mounting portion 51 corresponding to the shape of the mounting port 61, and the mounting portion 51 passes through the mounting port 61, so that the mounting port 61 circumferentially limits the mounting portion 51. During on-site installation, when the insulating connecting pipe 300 is connected to the curtain wall air conditioner, the insulating connecting pipe 300 extends into the second part 132 of the first space and is connected to the valve assembly 5 by threading, which can prevent the valve assembly 5 from rotating circumferentially. This can not only speed up the connection construction speed, but also avoid damage to the connection between the valve assembly 5 and the heat exchange unit 3 or the heat exchange unit 3 due to rotation.

[0058] like Figure 6 As shown, the sheet metal part 6 is connected to the housing 1 of the valve assembly 5 by a fixing member such as a screw, and the fixing member can be arranged along the extension direction perpendicular to the mounting portion 51 or along the extension direction of the mounting portion 51, so as to limit the position of the valve assembly 5 in the extension direction of the mounting portion 51. During on-site installation, when the insulating connecting pipe 300 is connected to the curtain wall air conditioner, the insulating connecting pipe 300 extends into the second part 132 of the first space and is connected to the valve assembly 5 by threading, which can prevent the valve assembly 5 from moving along the extension direction of the mounting portion 51, and avoid damage to the connection between the valve assembly 5 and the heat exchange unit 3 or the heat exchange unit 3 due to forced movement along the extension direction of the mounting portion 51.

[0059] In other embodiments, the sheet metal part 6 may have a mounting port 61, and the housing of the valve assembly 5 may have a mounting portion 51, and the mounting portion 51 passes through the mounting port 61. The housing of the valve assembly 5 has a plurality of fixing portions 52 distributed along the circumference of the mounting portion 51. The sheet metal part 6 is connected to the plurality of fixing portions 52 respectively by fixing members such as screws and bolts, and the fixing members are arranged along the extension direction of the mounting portion 51, so as to limit the position of the valve assembly 5 in the extension direction of the mounting portion 51 and to limit the circumferential position of the mounting portion 51. During on-site installation, when the heat-insulated connecting pipe 300 is connected to the curtain wall air conditioner, the heat-insulated connecting pipe 300 extends into the second part 132 of the first space and is connected to the valve assembly 5 by threading, which can prevent the valve assembly 5 from rotating circumferentially and moving along the extension direction of the mounting portion 51, which can not only speed up the connection construction speed, but also avoid damage to the connection between the valve assembly 5 and the heat exchange unit 3 or the heat exchange unit 3 due to rotation.

[0060] Corresponding to the above structure, Figure 6As shown, the end wall of the shell 1 corresponding to the second part 132 of the first space may have two openings 16, and the two openings 16 are respectively used for the insertion of two connecting pipes 300, and the two connecting pipes 300 are respectively used to communicate with the inlet and outlet of the heat exchange unit 3.

[0061] As a feasible method, the bottom of the first space 13 may have a water receiving pan, which is located below the heat exchange unit 3 and the valve assembly 5 to collect condensed water generated on the heat exchange unit 3 and the valve assembly 5. The housing 1 has a drain port 15 connected to the water receiving pan. For example, the drain port 15 may be provided on the end wall of the housing 1 and may be provided together with the opening 16. Figure 7 This is a schematic diagram of a housing of a curtain wall air conditioner having a level gauge in an embodiment of the utility model. Figure 8 for Figure 7 The enlarged schematic diagram of point A in the figure is as follows: Figure 7 and Figure 8 As shown, at least one level 7 is installed on the housing 1, and in the installation direction of the level 7, one end of at least one level 7 faces the direction of the drainage port 15. In this embodiment, the indicator line corresponding to the level 7 may not be in the middle of the level 7, but deviates from a distance away from the drainage port 15. When the construction personnel install the curtain wall air conditioner, the bubble in the level 7 needs to reach the indicator line, so that the curtain wall air conditioner is slightly lower at one end of the drainage port 15. When there are two level 7, the installation directions of the two level 7 can be perpendicular to each other on the horizontal plane. Further, the end surface of the bottom wall of the housing 1 facing downward can have a lower concave portion, and the level 7 can be installed in the lower concave portion. When the construction personnel install the curtain wall air conditioner, the construction personnel can see the level 7 by looking up, so that the drainage port 15 of the curtain wall air conditioner can be slightly lowered by the level 7, so that the water in the water receiving tray can automatically flow to the drainage port 15, so as to facilitate the discharge of the water in the water receiving tray.

[0062] It should be noted that the curtain wall air conditioner in the present application is an indoor unit of a non-wall-mounted air conditioner, and the curtain wall air conditioner can be a ceiling-mounted curtain wall air conditioner such as a fan coil unit or a central curtain wall air conditioner.

[0063] Fig. 9 Schematic diagram of the structure of the curtain wall air conditioner installation position in the embodiment of the utility model, as shown in FIG. Fig. 9As shown, the curtain wall air conditioner in the present application can be installed in a suspended ceiling. Further, the curtain wall air conditioner can be installed in a suspended ceiling 100 above a window 200. The suspended ceiling 100 where the curtain wall air conditioner is installed may include a side 101 and a bottom 102, and an air inlet port 1011 with a grille 400 may be provided at the side 101, and the air inlet port 1011 faces the side away from the window 200, and an air outlet port 1021 with a grille 400 may be provided at the bottom 102. The notch 12 of the curtain wall air conditioner corresponds to the air inlet port 1011, and the air outlet 11 of the curtain wall air conditioner facing downward corresponds to the air outlet port 1021. When the curtain wall air conditioner is cooling, the temperature near the indoor side of the window 200 can be effectively reduced by the above method, solving the problem of excessive temperature near the indoor side of the window 200 due to sunlight.

[0064] When the curtain wall air conditioner needs to be repaired, the maintenance personnel only need to remove the grille 400 of the air inlet port 1011, and then they can reach into the second space 14 of the curtain wall air conditioner to replace or repair the cross-flow fan; or, they can reach into the curtain wall air conditioner to remove the inspection panel, and then reach into the second part 132 of the first space to repair the valve assembly 5, etc.
