Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a terminal device of an air conditioning system. Background Art

[0002] In the terminal device of the air conditioning system, the air sucked in is blown out by a fan so that the air flows through the heat exchange unit for heat exchange, thereby achieving temperature regulation of the air. Generally speaking, the heat exchange unit has a plurality of heat exchange tubes, each of which includes a curved tube section formed by bending, a curved tube section connected by welding, and a straight tube section arranged in parallel. Therefore, the medium for heat exchange with the air introduced into the terminal device of the air conditioning system needs to be divided into each heat exchange tube through a liquid distributor, and then a liquid collector is required to collect the medium in each heat exchange tube and discharge it centrally. Since the liquid distributor and the liquid collector are arranged on at least one side of the two sides of the heat exchange unit, when the fan blows out the sucked air, part of the air will flow into the cavity in the terminal device of the air conditioning system occupied by the liquid distributor and the liquid collector to generate vortexes and thus emit noise, and part of the air will also leak through the gaps at the liquid inlet joint connected to the liquid distributor and the liquid outlet joint connected to the liquid collector, thus causing the air volume of the air outlet of the actual air conditioning system terminal device to be reduced. In order to ensure that the air volume at the air outlet of the terminal device of the actual air-conditioning system meets the requirements, it is necessary to further increase the fan power, which will cause the noise emitted by the fan to increase relatively and also increase energy consumption.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0052] In order to solve the problem of high noise and high energy consumption of the air conditioning system terminal device when the air is discharged, an air conditioning system terminal device is proposed in the embodiment of the present application. Figure 1 Schematic diagram of the structure of the air conditioning system terminal device (water collecting plate not shown) in the embodiment of the utility model, as shown in FIG. Figure 1 As shown, the air conditioning system terminal device includes: a first housing assembly 2, a heat exchange unit 3, a fan 1, and a liquid distributor 41 and / or a liquid collector 42. The air conditioning system terminal device may include but is not limited to one of the following: a fan coil unit, a multi-connected air conditioning unit indoor unit, a duct air supply air conditioning unit indoor unit, etc.

[0053] A first space 21 is formed in the first housing component 2. The first space 21 can be used to accommodate and install at least part of the heat exchange unit 3. An air outlet 22 is formed on the first housing component 2, and the air outlet 22 is used to output the air after heat exchange with the heat exchange unit 3.

[0054] like Figure 1As shown, the heat exchange unit 3 has a plurality of heat exchange tubes 31, through which a heat exchange medium flows, and the heat exchange medium exchanges heat with the air flowing outside the heat exchange tube 31, thereby adjusting the temperature and / or humidity of the air. A single heat exchange tube 31 includes a straight tube section 311 arranged in parallel, a curved tube section 312 formed by bending, and / or a curved tube section 312 connected by welding. The curved tube section 312 connects the straight tube section 311, thereby forming a heat exchange tube 31 that meanders back and forth. At least part of the straight tube section 311 of the heat exchange tube 31 can be arranged in the first space 21. The fan 1 is used to make the air blown out from the outlet of the fan 1 flow through the straight tube section 311 of the heat exchange tube 31 in the first space 21 and then be discharged from the air outlet 22. The air blown out from the outlet of the fan 1 exchanges heat with the heat exchange medium in the heat exchange tube 31 when flowing through the straight tube section 311 of the heat exchange tube 31. The two ends of the straight tube section 311 in one heat exchange tube 31 are connected to other straight tube sections 311 through the bent tube sections 312. The bent tube section 312 at at least one end of the heat exchange tube 31 can be arranged in the first space 21, so that the heat exchange rate between the heat exchange unit 3 and the air can be effectively improved. The bent tube section 312 at at least one end of the heat exchange tube 31 can also be arranged outside the first space 21.

[0055] Since the heat exchange unit 3 has a plurality of heat exchange tubes 31, the heat exchange medium input to the air conditioning system terminal device through the pipeline needs to pass through the liquid separator 41 and then flow into the plurality of heat exchange tubes 31 respectively, so the outlet of the liquid separator 41 is respectively connected with the inlet of the plurality of heat exchange tubes 31. Similarly, the heat exchange medium flowing out of the outlets of the plurality of heat exchange tubes 31 needs to be gathered by the liquid collector 42 and then output together through the pipeline, and the inlet of the liquid collector 42 is respectively connected with the outlet of the plurality of heat exchange tubes 31. The liquid separator 41 and / or the liquid collector 42 are arranged outside the first space 21. For example, the liquid separator 41 and / or the liquid collector 42 can be arranged in other spaces in the air conditioning system terminal device isolated from the first space 21, or can be arranged outside the first shell assembly 2, such as in a space outside the air conditioning system terminal device.

[0056] Since the liquid distributor 41 and / or the liquid collector 42 are arranged outside the first space 21 in the present application, when the fan 1 blows out the inhaled air, no air will flow into the space occupied by the liquid distributor 41 and the liquid collector 42, so no vortex will be generated and noise will be emitted, and no air will leak through the gaps at the liquid inlet joint connected to the liquid distributor 41 and the liquid outlet joint connected to the liquid collector 42. In addition, since the vortex of the heat exchange airflow is reduced, the heat exchange rate between the heat exchange tube 31 and the air can be effectively improved, the rotation speed of the fan can be reduced at the same air output, and the energy consumption of the terminal device of the air-conditioning system can be reduced to a certain extent, thereby further reducing the noise emitted by the fan. In summary, the terminal device of the air-conditioning system in the present application can effectively reduce the noise decibel, and can effectively reduce the energy consumption of the fan 1 at the same air output.

[0057] As is feasible, in one embodiment, if Figure 1 As shown, the air conditioning system terminal device may include: a first isolation component 5, the first isolation component 5 divides the first housing component 2 into a first space 21 and a second space 23. The first space 21 and the second space 23 are separated, and the air in the first space 21 is basically unable to flow into the second space 23. The liquid distributor 41 and / or the liquid collector 42 may be arranged in the second space 23. In the above manner, it is possible to prevent the air blown out by the fan 1 and flowing into the first space 21 from entering the second space 23 where the liquid distributor 41 and / or the liquid collector 42 are located, thereby avoiding the generation of vortices and noise.

[0058] In this embodiment, the curved pipe section 312 at one end of the heat exchange pipe 31 may be disposed in the second space 23 .

[0059] The first isolation assembly 5 can not only play a role of separation, but also play a role of fixing the heat exchange unit 3. As feasible, the first isolation assembly 5 may include: a heat exchange unit right plate 51 having a plurality of first through holes and a first connecting plate assembly 52. ​​The straight pipe section 311 of the heat exchange unit 3 can pass through the plurality of first through holes respectively, so that the heat exchange unit right plate 51 can fix the heat exchange tube 31. The heat exchange unit right plate 51 can be connected to the first shell assembly 2 through the first connecting plate assembly 52. ​​The heat exchange unit right plate 51 and the heat exchange tube 31 together can form a heat exchange unit 3 that is easy to install.

[0060] Since the other end of the heat exchange tube 31 also has a curved tube section 312, it is feasible to: Figure 2 Schematic diagram of the structure of the air conditioning system terminal device in another angle in the embodiment of the utility model. Figure 2 As shown, the air conditioning system terminal device may include: a second isolation component 6, which divides the first shell component 2 into a first space 21 and a third space 24. The curved pipe section 312 at the other end of the heat exchange tube 31 can be arranged in the third space 24. Similarly, the second isolation component 6 can not only play a role of separation, but also play a role in fixing the heat exchange unit 3. As a feasible method, the second isolation component 6 may include: a left plate of the heat exchange unit with multiple second through holes and a second connecting plate assembly. The straight pipe section 311 of the heat exchange unit 3 passes through the multiple second through holes respectively, so that the left plate of the heat exchange unit fixes the heat exchange tube 31. The left plate of the heat exchange unit is connected to the first shell component 2 through the second connecting plate assembly.

[0061] In order to achieve the fixation between the first connecting plate assembly 52 and the right plate 51 of the heat exchange unit, in a feasible implementation, Figure 4Schematic diagram of the structure of the first connecting plate and the right plate of the heat exchange unit in two different implementations in the embodiment of the utility model. Figure 4 As shown, the first connecting plate assembly 52 may include a first connecting plate 521. The first connecting plate 521 has a flange 53, and the right side plate 51 of the heat exchange unit has a flange 53. The flange 53 of the first connecting plate 521 abuts against the flange 53 of the right side plate 51 of the heat exchange unit and is fixedly connected. For example, a bolt or a screw may be passed through the abutment between the flange 53 of the upper part of the first connecting plate 521 and the flange 53 of the lower part of the right side plate 51 of the heat exchange unit and then tightened with a nut to connect the two together.

[0062] In another possible implementation, if Figure 4 As shown, the first connecting plate assembly 52 may include a first connecting plate 521. The edge of the first connecting plate 521 has a first notch portion 5211 corresponding to the heat exchange tube 31 located at the edge. Part of the first connecting plate 521 is arranged in contact with and overlapped with part of the right plate 51 of the heat exchange unit, and the first notch portion 5211 of the first connecting plate 521 presses against the heat exchange tube 31 to limit the heat exchange unit 3. Since there is a gap between adjacent heat exchange tubes 31, the first notch portion 5211 is partially inserted into the above gap, and most directions between the entire first connecting plate 521 and the heat exchange tube 31 are limited. Except for the direction in which the first notch portion 5211 is inserted into the gap of the heat exchange tube 31, other directions can basically be made unable to move.

[0063] The second connecting plate assembly can be fixed to the left plate of the heat exchange unit in a similar manner as the first connecting plate assembly 52. ​​Therefore, the second connecting plate assembly includes a second connecting plate, the second connecting plate has a flange, the left plate of the heat exchange unit has a flange, and the flange of the second connecting plate abuts against the flange of the left plate of the heat exchange unit to achieve a fixed connection. Alternatively, the second connecting plate assembly includes a second connecting plate, the edge of the second connecting plate has a second notch portion corresponding to the heat exchange tube 31 located at the edge, part of the second connecting plate is attached to and overlapped with part of the left plate of the heat exchange unit, and the second notch portion of the second connecting plate abuts against the heat exchange tube 31 to limit the heat exchange unit 3.

The second housing assembly 7 is connected to the first housing assembly 2. A fourth space 71 for installing the fan 1 is formed in the second housing assembly 7. The fan 1 is arranged in the fourth space 71.

[0065] The flanges of the second housing component 7 can be located on both sides of the first housing component 2 opposite to the flanges 53 of the first connecting plate 521, and the flanges of the second housing component 7, the flanges 53 of the first connecting plate 521 and the first housing component 2 are connected together through the fixing member. The above can strengthen the connection between the first connecting plate 521 and the first housing component 2, and at the same time make the whole formed by the first housing component 2 and the second housing component 7 more stable and firm.

[0066] As feasible, Figures 1 to 3 As shown, the air conditioning system terminal device may include: an electrical box 8, and the electrical box 8 and the second housing assembly 7 may be arranged in parallel. The electrical box 8 may correspond to the position of the second space 23 in the first housing assembly 2, and the electrical box 8 is located behind the second space 23. The electrical box 8 may be connected to the first housing assembly 2 and / or the second housing assembly 7 to achieve fixation. The electrical box 8 is used to install electrical equipment.

[0067] In order to collect the condensed water formed on the heat exchange unit 3 and prevent the condensed water from dripping from the terminal device of the air conditioning system, it is feasible to Figure 2 As shown, the first housing assembly 2 may include: a water collecting plate 25. The water collecting plate 25 may be located below the heat exchange unit 3, and the water collecting plate 25 is located below the liquid separator 41 and / or the liquid collector 42. The projections of the heat exchange unit 3, the liquid separator 41 and / or the liquid collector 42 in the gravity direction are all located within the area of ​​the water collecting plate 25, so that the condensed water formed on the heat exchange unit 3, the liquid separator 41 and / or the liquid collector 42 is collected by the water collecting plate 25.

[0068] In order to prevent condensation from forming on the outer wall of the water collecting plate 25, the inner wall of the water collecting plate 25 may have a heat-insulating layer. The flange of the first isolation component 5 may abut against the heat-insulating layer of the water collecting plate 25. Further, the flange of the first isolation component 5 may press the heat-insulating layer of the water collecting plate 25, so that a sufficient seal is formed between the flange of the first isolation component 5 and the water collecting plate 25, and the air flowing through the first space 21 cannot leak into the second space 23 through the flange of the first isolation component 5 and the water collecting plate 25.

[0069] As feasible, the first housing component 2 has a front wall surface 28, such as Figure 1 and Figure 3As shown, the air outlet 22 is located at the front wall 28, and the first isolation component 5 is sealed or abutted against the front wall 28 at the edge of one side of the air outlet 22, so that the air flowing through the first space 21 cannot leak into the second space 23 through the first isolation component 5 and the front wall 28. Similarly, the second isolation component 6 is sealed or abutted against the front wall 28 at the edge of the other side of the air outlet 22, so that the air flowing through the first space 21 cannot leak into the third space 24 through the second isolation component 6 and the front wall 28.

[0070] like Figures 1 to 3 As shown, the first shell assembly 2 may be provided with a first condensate outlet joint 26 and a second condensate outlet joint 27 on opposite sides thereof. The first condensate outlet joint 26 is connected to one side of the water collecting plate 25 to discharge the condensate collected in the water collecting plate 25. The second condensate outlet joint 27 is connected to the other side of the water collecting plate 25 to discharge the condensate collected in the water collecting plate 25. When the terminal device of the air-conditioning system is actually installed, the water collecting plate 25 may be inclined toward any one of the two opposite sides of the first shell assembly 2. With the above structure, no matter which side of the two opposite sides of the first shell assembly 2 the water collecting plate 25 is inclined toward, the condensate collected by the water collecting plate 25 may be discharged smoothly through the condensate outlet joint on the corresponding side.
