Batch type pre-cooling method and equipment for zero-load passive refrigeration box

The invention relates to a zero-load passive refrigeration box batch type pre-cooling method and equipment, and the method comprises the steps: S1, after a signal that a to-be-pre-cooled refrigerant starts to be pre-cooled after entering a refrigeration house is received, according to the current temperature of the refrigerant, the temperature field and wind field information of the refrigeration house and the position of the refrigerant are combined, the required pre-cooling time is determined; s2, recording the accumulated continuous pre-cooling duration of each refrigerant; s3, after a delivery request of the refrigerants is received, the corresponding refrigerants with the accumulated continuous pre-cooling duration reaching the required pre-cooling duration are selected for delivery according to the difference value between the accumulated continuous pre-cooling duration and the required pre-cooling duration in a descending sequence; and S4, the refrigerant is subjected to standing at the set buffer temp
