COLD STORAGE VENTILATION SYSTEM AND PRESSURE RELIEF VALVE APPARATUS THEREOF

摘要

The present invention relates to a refrigeration depot ventilation system for a polar ship, and a pressure relief valve device for the refrigeration depot ventilation system. In order to discharge the odor generated in the refrigeration depot, the pressure difference between the inside of the storage compartment and the corridor Thereby effectively discharging the odor of the storage room to the outside, and preventing the outside low temperature air in the polar waters from flowing back into the refrigeration warehouse when the odor is discharged, thereby effectively preventing damage to the air conditioning equipment and related electronic equipment.
