Refrigerating and humidity-regulating system for use in a container

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. In one modified embodiment, the solid adsorptive material is formed in a cylindrical shape and disposed rotatably about its own axis, the air circulation route is partitioned into an inside air circulation zone and an outside air circulation zone in such a manner that the cylindrical solid adsorptive material may alternately pass through the inside air circulation zone and the outside air circulation zone during its one revolution, and inside air and outside air are simultaneously and continuously circulated through the respective air circulation zones in the air circulation route.
