Description

Technical Field

[0001] The present application relates to the technical field of air conditioning equipment, and in particular to a cooling device for an outdoor unit of a commercial air conditioner. Background Art

[0002] Air conditioning, or air conditioner, refers to equipment that uses artificial means to adjust and control parameters such as temperature, humidity, and flow rate of ambient air in buildings or structures. At present, the outdoor unit of the computer room air conditioner relies on a fan to blow natural wind to the condenser fins to take away heat. In recent years, the outdoor temperature in summer has been higher and higher than in previous years. Due to the high temperature of natural wind, the heat taken away is relatively limited, and the unit energy efficiency ratio is low. Therefore, the compressor needs to continuously perform power cycles for a long time, which increases energy consumption and shortens the service life of the air conditioner.

[0003] At present, the air conditioning cooling equipment can effectively help the air conditioning outdoor unit to cool down. The air conditioning cooling equipment includes a chassis, a water tank arranged in the chassis and a high-pressure pump connected to the water tank. Several pipes are connected to the high-pressure pump. Several atomizing nozzles for spraying water in the water supply tank are arranged on the pipes. When the air conditioning outdoor unit needs to be cooled down, the water in the water tank is sprayed out from the atomizing nozzles along several pipes through the high-pressure pump to cool down the air conditioning outdoor unit.

[0004] With respect to the above-mentioned related technologies, the following defects were found: the atomizing nozzles on several pipes can cool down more than one air-conditioning outdoor unit, but when the temperature of one of the air-conditioning outdoor units is too high and needs to be cooled down, and the temperature of the other air-conditioning outdoor unit has not yet reached the temperature that needs to be cooled down, the above-mentioned structure may only be able to cool down the two air-conditioning outdoor units at the same time, and it is not easy to distinguish the air-conditioning outdoor units that need to be cooled down for cooling.

A first bending joint 24 is connected to the end of the first connecting pipeline 21 that passes through the third cabinet 13. The end of the first bending joint 24 that is away from the connection with the first connecting pipeline 21 is connected to the first extension pipeline 22. The end of the first extension pipeline 22 that is away from the connection with the first bending joint 24 is connected to the second bending joint 25. The end of the second bending joint 25 that is away from the connection with the first extension pipeline 22 is connected to the second extension pipeline 23. The second extension pipeline 23 is located on one side of the heat dissipation fin plate of the air conditioner outdoor unit.

[0040] Reference Figure 1 , Figure 2 and Figure 4 In the present embodiment, the five-way valve 1321 adopts a circular distribution pattern of the other four pipe openings except for the pipe opening at one end connected to the main solenoid valve 132. Taking the connection mode between the main solenoid valve 132 and the sub-solenoid valve 133 on the right side and the pipeline 2 as an example, in order to reasonably distribute the pipeline 2, the pipe openings at one end of the second bend joints 25 located on the front and rear sides away from the connection with the first extension pipeline 22 are all arranged away from the second bend joints 25 located on the upper side, and the third extension pipeline 26 is connected to the pipe opening at one end of the second bend joints 25 located on the front and rear sides away from the connection with the first extension pipeline 22, and the third extension pipeline 26 is connected to the end of the third extension pipeline 26 away from the connection with the second bend joint 25. The third bend joint 27 is connected to the second extension pipeline 23.

[0041] Reference Figure 1 and Figure 4 The first bend joint 24 located on the lower side is arranged with the end of the pipe opening away from the part connected to the sub-solenoid valve 133 facing forward, and a fourth extension pipe 28 is connected to the end of the pipe opening of the first bend joint 24 located on the lower side away from the part connected to the sub-solenoid valve 133, and the fourth extension pipe 28 is connected to the fourth bend joint 29 at one end away from the connection with the first bend joint 24, and the fourth bend joint 29 is connected to the first extension pipe 22 at one end away from the connection with the fourth extension pipe 28, and the first extension pipe 22 is connected to the second bend joint 25 at one end away from the connection with the fourth bend joint 29, and the second bend joint 25 is connected to the second extension pipe 23 at one end away from the connection with the first extension pipe 22.

[0043] The implementation principle of a cooling device for a commercial air conditioner outdoor unit in the embodiment of the present application is: set in advance, for example, when the temperature of the air conditioner outdoor unit reaches 40 degrees Celsius, the cooling device starts spraying water mist, and stops spraying water mist when the temperature drops to 35 degrees Celsius;

[0044] When the fan of the air conditioner outdoor unit starts to rotate rapidly, the air pressure sensor 4 transmits this information to the electric control box 111. When it is detected that the temperature of the air conditioner outdoor unit reaches 40 degrees Celsius, the main electromagnetic valve 132 is started, and the sub-electromagnetic valve 133 is opened according to the situation. For example, when all the air conditioners outdoor units reach 40 degrees Celsius, all the sub-electromagnetic valves 133 are opened, and the water in the water tank 121 is sprayed out of the atomizing nozzle 3 through the pipe 2 to cool the air conditioner outdoor unit. When the temperature drops to 35 degrees Celsius, the sub-electromagnetic valve 133 is closed.

[0045] When the temperature of only a part of the air-conditioning outdoor unit reaches 40 degrees Celsius, the corresponding sub-solenoid valve 133 is opened, so that the water in the water tank 121 passes through the opened sub-solenoid valve 133 along the pipeline 2 and sprays water mist from the atomizing nozzle 3 to cool down this part of the air-conditioning outdoor unit. When the temperature drops to the set temperature of 35 degrees, the sub-solenoid valve 133 is closed. When the air-conditioning outdoor unit is closed, the main solenoid valve 132 is also closed.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
