ABSTRACT:
The cargo area of a refrigerated railroad car is cooled by convectors positioned along the upper side and walls of the cargo side and end walls of the cargo compartment of the car. The convectors are cooled by a supply of carbon dioxide snow in a bunker above the cargo compartment. Alternately, vents between the bunker and the cargo compartment and along the upper side and end walls of the cargo compartment enhance and direct carbon dioxide vapor circulation between the cargo area and the bunker. The convectors and the vents can be used independently or in combination.
