The specific interval is required to be determined according to the specific area of the evaporator 3, when the horizontal interval of the spray nozzles 706 is 300mm and the vertical interval of the spray branch pipes 702 is 320mm, which is equivalent to the minimum spray area, the spray of water mist is relatively dense, and the method is suitable for the condition that the area of the evaporator 3 is not large; when the horizontal spacing of the spray nozzles 706 is 350mm and the vertical spacing of the spray branches 702 is 360mm, the spray area is relatively maximum, which is suitable for larger units of evaporator 3.
It should be noted that, in the above-described manner of determining the interval, when the vertical interval of the shower branch pipes 702 is 360mm, the interval corresponding to the shower branch pipes 702 is maximized, so that the shower branch pipes 702 adjacent in the up-down direction are farthest apart, and when considering the size of the shower area of the shower nozzle 706, it is preferable to set the horizontal interval of the shower nozzle 706 to 300mm, the interval to the minimum, and the shower coverage area to the maximum, so as to ensure that the evaporator 3 can be fully covered.
In some embodiments, a water receiving disc 8 is arranged below the evaporator 3, a water collecting port 9 is arranged at the bottom of the water receiving disc 8, water on the water receiving disc 8 is collected at the water collecting port 9, and then the water collecting port 9 and the water storage tank 5 are connected through a water collecting pipe to form a circulation loop.
Optionally, a water supplementing port is further provided on the water storage tank 5, and the water supplementing port is connected to an external water supplementing device through a pipeline, and water is supplemented into the water storage tank 5 through the water supplementing port by the external water supplementing device, so that water in the water storage tank 5 is guaranteed to meet the spraying requirement.
Further, the evaporator 3 is a fin heat exchanger.
In the actual use process, before the machine set is started, whether tap water circulates through a pipeline connected to a water supplementing port or not is checked, when the machine set is started, the water storage tank 5 is fully filled with the tap water through the water supplementing port, the water pump 6 starts to act, the water of the water storage tank 5 is conveyed to the fan-shaped spray nozzles 706 from the spray main pipe 701 to the spray branch pipe 702 at high pressure through the water pump 6, the water is uniformly sprayed to fins of the evaporator 3 through the fan-shaped spray nozzles 706, dust stuck to the fins is washed to the water receiving disc 8 through the high-pressure water mist, and then flows back to the water storage tank 5 through the water collecting port 9 at the bottom of the water receiving disc 8 to form circulation through a water return pipe. Because the unit runs for a long time, the water in the water storage tank 5 is always recycled and becomes more turbid, a water outlet is formed in the water storage tank 5, when the set accumulated time is reached, the water outlet is opened to drain turbid water, and then the water supplementing port is reused to supplement the water in the water storage tank 5.
