Abstract: A refrigerating and humidity-regulating system for a container is disclosed, which comprises a refrigerating unit having a humidity-regulating apparatus assembled therein. This humidity-regulating apparatus includes a solid adsorptive material, an air heater, an air blowing means, and an air circulation route for circulating inside and outside air through the air heater and the solid adsorptive material, in that sequence. The solid adsorptive material may be formed as a fixed bed, and inside air and outside air are alternately circulated through the fixed bed. In one preferred embodiment, the above-mentioned humidity-regulating apparatus is assembled in multiple in the refrigerating unit, wherein in each of the humidity-regulating apparatuses the solid adsorptive material is formed as a fixed bed, and inside air and outside air are alternately circulated through the fixed bed in each humidity-regulating apparatus.

Abstract: A box member for refrigerate transportation for containing perishables therein and transporting thereby. A gas fed from a refrigerating unit flows from above to below through a gas flow path and gas flow holes of an insulating plate in the vicinity of a ceiling of the box member. A damper device for closing the gas flow path during defrosting is provided in the vicinity of an inlet of the gas flow path. An air shut-off curtain which is suspended from the ceiling and a protecting mechanism thereof are provided at the rear portion of the box member. A water tank is provided at the inside of a front corner post, and a level gauge for visually confirming the water level of the water tank and a water feed port to the water tank are provided at the outside of the front corner post. The level gauge is provided with a discharge valve and a protective net.
