Air cooler defrosting control method, device, equipment and system and air cooler

Abstract

The invention relates to an air cooler defrosting control method, device, equipment and system and an air cooler. The air cooler defrosting control system comprises at least one set of defrosting detection device. The defrosting detection device comprises a light emitter arranged on the air inlet side of an evaporator and a light receiving assembly arranged on the air supply side of the evaporator. The method comprises the following steps: induction signals sent by the light receiving assembly after receiving light emitted by the light emitter are acquired in real time; the induction signals are analyzed, and frosting information corresponding to the induction signals is determined; and according to the frosting information, the light receiving assembly is controlled to work, and a switch control instruction is sent to a preset defrosting assembly so as to control the defrosting assembly to conduct defrosting. According to the scheme, the light emitted by the light emitter penetrate through the evaporator and irradiate the light receiving assembly, whether the light is refracted or not is judged through feedback of the light receiving assembly, the frosting information is determined, the frosting condition on the evaporator is monitored, the defrosting accuracy is improved, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of air cooler defrosting, in particular to a method, device, equipment, system and air cooler defrosting control method. Background technique [0002] The industrial air cooler uses the principle of evaporative cooling of all fresh outdoor air to cool down and conduct convective ventilation with the room to achieve the purpose of indoor ventilation and cooling. Industrial air coolers are generally used in cold storage and cold chain logistics refrigeration environments. In current cold storage equipment, air coolers have a wide range of uses. [0003] The air cooler works in a low-temperature cold storage environment for a long time. During refrigeration, affected by the low temperature and humidity in the storage, frost will continue to form on the evaporator. The cooling effect of the air cooler is affected, so the air cooler needs to be defrosted frequently. In the prior art, methods such as electric de...
