Abstract

A vehicle (14) having first and second cargo spaces (32,34) to be conditioned by a transport refrigeration unit (12), with the vehicle having a front wall (24) and a rear wall (26). A partition (30) in the vehicle defines the first and second cargo spaces, which extend side-by-side from the front wall to the rear wall. The rear wall is provided with separate doors (36,38) for gaining access to the first and second cargo spaces. The transport refrigeration unit includes a frame (44) supporting first and second evaporator units (50,52). The frame and evaporator units are mounted on the outside front wall of the vehicle, with the first and second evaporator units being in air flow communication with the first and second cargo spaces, respectively, via suitable openings (40,42) in the front wall. Electrical control independently controls the first and second evaporator units to condition the air in the first and second cargo spaces.
