The present invention relates to a cold storage ventilation system for an arctic ship, a pressure relief valve apparatus thereof, an arctic ship having the same, and a cold storage ventilation method, which efficiently discharges offensive odors in a storage room of the cold storage to the outside using the pressure difference between the inside of the storage room and a corridor to discharge offensive odors generated in the cold storage, and effectively prevents damage to air conditioning equipment and related electronic equipment by preventing external low-temperature air in an arctic sea area from flowing backward to the inside of the cold storage when the offensive odors are discharged. The cold storage ventilation system for an arctic ship comprises: a cold storage which has multiple storage rooms and a corridor; an air supply duct which supplies fresh air to the storage rooms; pressure relief valve apparatuses which are installed in partitions formed between the storage rooms and the corridor; and an offensive odor discharge device which discharges offensive odors flowing into the corridor to the outside of the cold storage.
본 발명은 극지용 선박의 냉동창고 환기시스템, 그 냉동창고 환기시스템의 프레셔 릴리프 밸브장치, 그 냉동창고 환기시스템을 구비하는 극지용 선박, 및 냉동창고 환기방법에 관한 것으로, 냉동창고 내부에서 발생하는 악취를 배출시키기 위하여 냉동창고의 저장룸 내부와 복도의 압력차이를 이용하여 저장룸의 악취를 외부로 효율적으로 배출시키도록 하며, 악취 배출시 극지 해역의 외부 저온 공기가 냉동창고 내부로 역류하지 않도록 함으로써, 공조장비 및 관련 전자 장비의 손상을 효과적으로 방지할 수 있다.
