Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an outdoor unit of an air conditioning. Background Art

[0002] At present, the condensation temperature of air-cooled outdoor units is high, resulting in low operating efficiency, high energy consumption, and high operating costs. In addition, in the hot summer, if the outdoor unit is installed in poor conditions and the heat dissipation effect is poor, the inlet air temperature will be too high, which will greatly reduce the cooling capacity of the outdoor unit or even stop working. In order to solve the above problems, a spray cooling system can be set up to reduce the air temperature at the outdoor unit, improve the heat dissipation environment of the outdoor unit, and thus ensure the air conditioning effect. However, when setting up the spray system, a spray pipe bracket must be built near the outdoor unit, which increases the construction workload and occupies a certain amount of space. This requires more space for centralized outdoor units, especially for outdoor unit platforms in super high-rise buildings, which is not conducive to the implementation of the spray system.

[0025] Please also read Figures 1 to 5 Now, the air conditioner outdoor unit provided by the embodiment of the utility model is described.

[0026] like Figures 1 to 3 As shown, the air conditioner outdoor unit of the embodiment of the utility model comprises: an air conditioner housing 100 and a spray system 200;

[0027] Reference Figures 1 to 3The air-conditioning housing 100 is provided with an air inlet 110, an air outlet 120, and an air inlet grid 130; the air inlet grid 130 is provided at the air inlet 110; the air-conditioning housing 100 of the air-conditioning outdoor unit has a condenser and a fan, which is used to send air from the air inlet 110 into the air-conditioning housing 100, and then send it out from the air outlet 120, so as to cool the condenser. The air inlet grid 130 is a protective grid, which is used to prevent small animals or other foreign objects from entering the air-conditioning housing 100.

[0028] Reference Figures 1 to 3 The spray system 200 includes an in-machine spray main pipe 210, an out-machine spray main pipe 220, a plurality of spray branch pipes 230, and a plurality of nozzles 340; the in-machine spray main pipe 210 is located on the inner side of the air conditioning housing 100, the spray branch pipe 230 is arranged on the air inlet grid 130, the nozzle 340 is arranged on the spray branch pipe 230, and the out-machine spray main pipe 220 is connected with the spray branch pipe 230 through the in-machine spray main pipe 210.

[0029] Reference Figures 1 to 3 The external spray main pipe 220 is used to connect the spray equipment to transport the atomized water vapor to the spray branch pipe 230, so that the nozzle 340 on the spray branch pipe 230 sprays the mist vapor to the air inlet 110, so as to reduce the air temperature at the air inlet 110 of the air conditioner outdoor unit, improve the heat dissipation environment of the air conditioner outdoor unit, and thus ensure the air conditioning effect. The spray branch pipe 230 is arranged on the air inlet grid 130, so that the spray branch pipe 230 can cooperate with the air inlet grid 130 to form a protective grid for the air conditioner outdoor unit. Then, as a part of the protective grid, the spray branch pipe 230 does not need to occupy additional space outside the shell. Moreover, before leaving the factory, the external spray dry pipe 220 of the spray system 200, the internal spray dry pipe 210, multiple spray branch pipes 230, and multiple nozzles 340 can be directly installed on the air conditioner shell 100, so that the spray system 200 can be connected to the air conditioner outdoor unit for overall delivery. After arriving at the site, the construction personnel do not need to lay the spray system 200 additionally, and only need to connect the external spray dry pipe 220 to the pipe of the spray equipment to complete the installation.

[0030] Reference Figures 1 to 3In some embodiments of the utility model, the air conditioner outdoor unit further includes: a main pipe solenoid valve 300; the main pipe solenoid valve 300 is arranged on the external spray main pipe 220. The main pipe solenoid valve 300 is used to determine whether the external spray main pipe 220 is connected to the spray device. When the main pipe solenoid valve 300 is opened, the external spray main pipe 220 is connected to the spray device, allowing the water vapor of the spray device to enter the internal spray main pipe 210 and the spray branch pipe 230, and allowing the water vapor to be sprayed from the nozzle 340 to the surrounding environment of the air inlet 110, so as to reduce the air inlet temperature at the air inlet 110, improve the heat dissipation environment of the outdoor unit, and thus ensure the air conditioning effect. When the main pipe solenoid valve 300 is closed, the external spray main pipe 220 is closed, the water vapor of the spray device cannot enter the internal spray main pipe 210, and the nozzle 340 cannot spray water vapor.

[0031] The air conditioner outdoor unit has a control system; the control system can directly read the condensation temperature inside the air conditioner unit, and the control system is connected to the signal of the main pipe solenoid valve 300. The control system can be a PLC controller or an MCU controller, and the control system can read the real-time condensation temperature of the air conditioner outdoor unit. If the real-time condensation temperature is greater than the preset value (the preset value can be adjusted according to the actual situation, in this embodiment, the preset value can be 38 degrees to 42 degrees), the controller controls the main pipe solenoid valve 300 to open, and the signal of the main pipe solenoid valve 300 opening will be fed back to the spray device, and the spray device will output the spray to the spray main pipe 210 in the machine, so that the nozzle 340 on the spray branch pipe 230 sprays water mist at the air inlet 110 to spray and cool down. When the real-time condensation temperature is less than the spray closing value (the spray closing value can be adjusted according to the actual situation, in this embodiment, the spray closing value can be 37 degrees), the controller controls the main pipe solenoid valve 300 to close, and the signal of the main pipe solenoid valve 300 closing will be fed back to the spray device, and the spray device will close to prevent the nozzle 340 from continuing to spray. It should be noted that the signal connection can be an electrical signal connection, a Bluetooth signal connection, etc.

[0032] Reference Figures 1 to 3 In some embodiments of the present invention, each of the spray branch pipes 230 is provided with a plurality of nozzles 340. That is, a spray branch pipe 230 is provided with a plurality of nozzles 340, so as to reduce the number of spray branch pipes 230 and make the pipeline of the spray system 200 simpler.

[0033] Reference Figures 1 to 3 On the basis of the above, the nozzle 340 can be arranged upward or downward. The direction of the nozzle 340 can be laid according to the actual situation, so that the water mist sprayed by the nozzle 340 can cover the entire air inlet 110 as much as possible to improve the cooling efficiency.

[0034] In some embodiments of the present invention, referring to Figures 1 to 3The air-conditioning outdoor unit is a top-outlet outdoor unit, that is, the air outlet 120 is arranged at the top of the air-conditioning housing 100, and the air inlet 110 is arranged at the side of the air-conditioning housing 100, then the air inlet grid 130, the spray branch pipe 230, and the nozzle 340 are all located at the side of the air-conditioning outdoor unit and supply air to the top. On the basis of the above, the air inlet 110 is arranged at the rear side and the left side of the air-conditioning housing 100, and the air inlet 110 is arranged at the air inlet grid 130, then both sides have the air inlet 110, so as to expand the air inlet area, expand the spray area, make the cooling effect of the spray system 200 more obvious, better improve the heat dissipation environment of the outdoor unit, and thus ensure the air conditioning effect.

[0035] In some embodiments of the present invention, referring to Figures 4 to 5 The air conditioner outdoor unit is a side-outlet outdoor unit, the air outlet 120 is arranged at the front side of the air conditioner housing 100, and the air inlet 110 is arranged at the rear side of the air conditioner housing 100. The corresponding air inlet grid 130, spray branch pipe 230, and nozzle 340 are all located at the rear side of the air conditioner outdoor unit, so that the spray system 200 is connected to the spray device.

[0036] In summary, the spray branch pipe 230 of the air conditioner outdoor unit of the present embodiment is arranged on the air inlet grid 130, and the spray branch pipe 230 is provided with a plurality of nozzles 340, so that the nozzles 340 on the spray branch pipe 230 spray water mist to the air inlet 110 of the air conditioner outdoor unit, so as to reduce the air temperature at the air inlet 110 of the air conditioner outdoor unit, improve the heat dissipation environment of the air conditioner outdoor unit, and thus ensure the air conditioning effect; and the spray branch pipe 230 is arranged on the air inlet grid 130, so that the spray branch pipe 230 can cooperate with the air inlet grid 130 to form a protective grid of the air conditioner outdoor unit, and the spray branch pipe 230 serves as a protective grid. The spray system 200 is a part of the air-conditioning outdoor unit, and there is no need to occupy additional space outside the shell, and there is no need to build an additional spray pipe bracket. The external spray dry pipe 220, the internal spray dry pipe 210, the multiple spray branch pipes 230, and the multiple nozzles 340 of the spray system 200 can be directly installed on the air-conditioning shell 100 before the air-conditioning outdoor unit leaves the factory, so that the spray system 200 is connected to the air-conditioning outdoor unit for overall delivery. After the construction personnel arrive at the site, there is no need to lay the spray system 200 additionally. They only need to connect the external spray dry pipe 220 to the pipe of the spray equipment to complete the installation, thereby reducing the construction workload and facilitating the installation of the spray system 200 on site.
