SHRIVELED PHENOMENON OF REEFER CONTAINER WALLS AND PRECAUTIONARY MEASURES DURING OCEAN TRANSPORTATION

摘要

Shriveled phenomenon of reefer container walls is one of the most important factors that influence ocean transportation safety. Theoretical and experimental researches have been made on the strength characteristics, performances of heat transfer, and performances of the insulated foam layers at super-low temperatures. Results show that there exists obvious high vacuum inside the reefer container, which is the main reason why the foam layer has been cracked and reefer side walls shriveled and distorted. The vacuum-release valve controlled by air pressure differences has been designed to make the air pressure inside and outside of the reefer balance, avoiding the side wall vacuum-shriveled and damaged.
