Intelligent defrosting method

Abstract

The invention discloses an intelligent defrosting method. The intelligent defrosting method comprises the following steps of judging a current temperature obtained by a defrosting thermal bulb and entering the defrosting processing step corresponding to each preset defrosting temperature threshold value. The defrosting processing steps comprise the following steps of: when the current temperature is higher than or equal to a first preset defrosting temperature threshold value, not entering the defrosting state and carrying out zero clearing on defrosting time interval timing; when the current temperature is lower than a second preset defrosting temperature threshold value, starting timing on the defrosting time interval timing; and when the current temperature is between the first preset defrosting temperature threshold value and the second preset defrosting temperature threshold value, ensuring the defrosting time interval timing in a hold mode, wherein the first preset defrosting temperature threshold value is higher than the second preset defrosting temperature threshold value. According to the intelligent defrosting method, the accurate and effective defrosting processing can be provided for a refrigerating unit; a user can select whether to defrost according to the actual condition of the unit; the condition of thawing without frost is prevented; the energy loss is reduced; and the refrigerating efficiency is improved.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to an intelligent defrosting method. Background technique [0002] During the operation of the refrigeration unit, as the evaporation temperature decreases, the evaporator will gradually frost. In order to improve the refrigeration efficiency and reduce the abnormal loss of energy, it is necessary to deal with the frost. Therefore, it is necessary to be able to timely and accurately Frost. At present, the defrosting method used by containers is basically timing defrosting. This defrosting method is simple and easy to operate. The defrosting time interval is set before each reefer boards the ship, and the container refrigeration unit will defrost according to this method during the entire voyage. Frost. This will cause the unit to perform unnecessary defrosting without defrosting. Especially in the case of global transportation, the unit has to operate at sea for a month or even longer. ...

This will cause the unit to perform unnecessary defrosting without defrosting

Especially in the case of global transportation, the unit has to operate at sea for a month or even longer. With the operation of the unit, the humidity in the cold box will continue to decrease, and the time interval for frosting will become longer and longer. The defrosting cannot be judged according to the actual situation in the box, and there will be a phenomenon of defrosting without frost, resulting in serious energy waste
