The air-cooler 10 is provided in a refrigerator.
The nozzle is used for spraying defrosting cooling water to the fins of the air cooler 10.
One end of the first pipe 11 is connected to the shower head.
The condenser 12 is used for generating defrosting cooling water and cooling water (for cooling the refrigerant of the unit when the refrigeration system is in normal operation), and it should be understood that the cooling water of the condenser 12 is used for cooling the refrigerant (when the refrigeration system is in normal operation), and the temperature of the defrosting cooling water is much lower than that of the cooling water.
A first output port of the condenser 12 is connected to the other end of the first pipe 11, so that the defrosting cooling water is delivered to the first pipe 11 through the condenser 12.
Preferably, a flushing frost water pump 111 is arranged in the first pipe 11, so that the flushing frost water in the condenser 12 is pumped to the spray head by the flushing frost water pump 111, and the spraying of the flushing frost cooling water on the fins of the air cooler 10 is realized.
One end of the second pipe 13 is connected to a second output port of the condenser 12 to deliver the condensed water into the second pipe 13 through the condenser 12.
A first input port of the collection tank 14 is connected to the other end of the second pipe 13 to recover the cooling water of the condenser 12 through the collection tank 14.
One end of the third tube 15 is connected to the air cooler 10 for recovering the defrosting cooling water that has washed the fins of the supercooling fan 10. That is, the defrosting cooling water sprayed from the spray head melts the frost on the fins of the air cooler 10 and flows into the third tube 15.
In this embodiment, one end of the third tube 15 is provided with a recovery structure which is located inside the air cooler 10 and is used for collecting defrosting condensate of the fins of the air cooler 10.
Further, the other end of the third pipe 15 is connected to a second input port of the collecting tank 14 to recover the water in the third pipe 15 through the collecting tank 14. It should be understood that the water recovered by the third tube 15 is condensed water, and the temperature is relatively low.
One end of the fourth tube 16 is connected to the output port of the collection box 14, and the other end of the fourth tube 16 is connected to the first input port of the condenser 12, so that the water in the collection box 14 can be transported to the condenser 12 through the fourth tube 16 for heat exchange, and the cold energy in the condensed water discharged by the air cooler 10 is recycled again, thereby reducing the discharge of the cold energy and saving resources.
Preferably, a circulation water pump 161 is provided in the fourth pipe 16 to pump the water in the collection tank 14 to the condenser 12 by the circulation water pump 161.
It should be understood that the condensed water conveyed by the fourth pipe 16 is injected from above the condenser 12 as water with a relatively low temperature input from the first input port of the condenser 12, and performs heat exchange by the superposition of the air coolers on the refrigerant (refrigerant in the refrigeration system) which needs to be cooled while being used in other refrigeration houses in the refrigeration system, thereby absorbing the heat of the refrigerant, and obtaining a cooling load on the other refrigeration systems being used. Meanwhile, the condensed water conveyed by the fourth pipe body increases the water amount through the defrosting effect when the air cooler washes frost, so that the function of supplementing water to the condenser 12 is achieved, and the water amount of the condenser system required to supplement tap water is reduced. That is to say, the condensed water conveyed by the fourth pipe 16 can effectively supplement the water loss of the pipeline and the condenser, and a water supplementing system is not needed, so that the effect of saving water resources is achieved.

It should be understood that the early warning time is set artificially, and when the working time of the air cooler 10 reaches the early warning time, the working time of the air cooler 10 is longer, frost is condensed, and therefore the frost needs to be defrosted.
Further, as shown in fig. 3-4, in some embodiments, the cold storage is relatively large (e.g. 10-50 meters), and a plurality of air coolers 10 are arranged at intervals along the length direction of the cold storage, wherein a lead screw 21 is further arranged along the length direction of the cold storage, and one end of the lead screw is fixedly connected with a driving motor 22, so that the lead screw 21 is driven by the driving motor 22 to rotate, and the driving motor 22 is electrically connected with the controller 17, and the driving motor 22 is controlled by the controller 17 to operate. Further, a sliding block 23 is screwed in the screw rod 21, so that the sliding block 23 slides along the screw rod 21 when the screw rod 21 rotates, and the spray head 20 is fixedly arranged in the sliding block 23, so that the spray head 20 is driven to slide by the sliding block 23.

It should be understood that, in the present embodiment, the camera 24 and the head 20 are disposed on the slide block 23 at intervals so that the camera 24 and the head 20 synchronously follow the slide block 23 to slide on the screw 21.
Specifically, the fins of the multiple air coolers 10 in the refrigeration storage are shot through the camera 24 so that a shot picture of the fins of each air cooler 10 can be obtained, the controller 17 analyzes whether the fins corresponding to the shot picture are frosted or whether the frosted thickness reaches a condition needing defrosting through the shot picture, if the condition needing defrosting is determined to be reached, the driving motor 22 is controlled to work so as to drive the screw rod 21 to rotate, the sliding block 23 drives the nozzle 20 to slide to the fin of the air cooler 10 corresponding to the condition reaching the defrosting condition, the condenser 12, the defrosting water pump 111 and the circulating water pump 161 are controlled to work, and the defrosting cooling water with higher temperature in the condenser 12 is used for defrosting the fins of the air coolers 10 corresponding to the condition reaching the defrosting condition through the nozzle 20 of the first pipe body 11.
Further, under the normal operating condition of the refrigeration house, the controller 17 controls the driving motor 22 to work at intervals, so that the driving motor 22 controls the screw rod 21 to rotate at intervals, and therefore the sliding block 23 is driven to slide on the screw rod 21 at intervals, when the sliding block 23 moves to the corresponding fin of the air cooler 10, the camera 24 is controlled to work to shoot the fin of the air cooler 10 to obtain a shot picture, and the controller judges whether the fin corresponding to the shot picture has a frosting phenomenon or whether the frosting thickness reaches a condition needing defrosting through the shot picture.
