Development of new concept air curtain (Air Return System) for idling-stop of transport refrigerator: suppressing door opening heat load

摘要

Keeping cold of the freezing container during idling-stop is the focus of transport refrigerator users. For this demand, we developed new concept air curtain ( Air Return System) that suppress door opening heat load nearly 75%( nearly 50% of allheat load). By this Air Return system, mean temperature inside container with idling-stop is sane as that without idling-stop.
