step h: the temperature controller is set at the required temperature, the carriage is pre-cooled for 1.5 hours to remove the heat retained in the carriage, and the refrigerating unit is closed during loading, so that the goods can be loaded quickly.
2. A refrigerator car safe use method according to claim 1, characterized in that: the coolant in step b is a mixture of glycol and water, in different proportions according to the actual conditions of the product, and should provide protection against freezing at-34 ℃ without opening the lid of the coolant tank when the coolant is hot.
3. A refrigerator car safe use method according to claim 1, characterized in that: and e, maintaining 13mm sag at the center of the span between the belt and the belt pulley to ensure the stable operation of the transmission mechanism.
4. A refrigerator car safe use method according to claim 1, characterized in that: if the temperature of the goods conveyed in the step h is not the ambient temperature, the goods are loaded into the carriage, the ambient temperature affects the temperature of the conveyed goods, so that the quality of the conveyed goods changes, the carriage needs to be precooled to the required temperature before loading, however, the refrigerating unit needs to be closed during loading, if the refrigerating unit is not closed, the fan of the evaporator of the refrigerating unit works, the front surface of the fan is positive pressure, the back surface of the fan is negative pressure, so that cold air is blown out from the upper part of the carriage, and the lower part can suck in hot air outside quickly, so that the temperature in the carriage rises quickly.
