ABSTRACT:
A method and system for conditioning the cargo containing space of a vehicle are disclosed wherein refrigerated or heated air is introduced into a supply duct and circulated through the cargo to a return duct. The return duct or ducts are preferably formed by movable reefer pallets or racks, controlled openings in the pallets regulating flow into the return duct to develop a uniform pressure differential between the cargo space and the return duct and achieve more uniform cooling. Heat barrier spacers are arranged on vertical walls to minimize heat passage to the cargo. A method and system are also disclosed for supplying refrigerated gas through a supply duct and returning it through a return duct, a control unit being normally responsive to a master temperature sensor arranged in an inlet, a sub-master temperature sensor being arranged for sensing freezing or chilling conditions and overriding the master temperature sensor.
