Abstract
A container for transporting a load in conditioned space air, where the container includes a number of walls defining a closed conditioned space with an ambient air intake opening and a conditioned space air exhaust opening provided on one of the container walls; a temperature control system for controlling the temperature of the conditioned space air; an ambient air exchange so system having a door movable relative to the exhaust and intake openings to thereby change the rate that conditioned space air is exchanged with ambient air, and a motor for repositioning the ambient air exchange door. The container also including a container controller in signal transmitting relation with the air exchange door repositioning motor. The controller sends signals to the repositioning motor to move the ambient air exchange door to a position which produces the required ambient air exchange rate to preserve the load.
