    摘要： A transport refrigeration system 10, and method of operating same, which includes a compressor 14, a receiver 26, an evaporator 42, an accumulator 44, and valve means 18 which initiates heating and cooling modes or cycles which utilize hot compressor gas. Instead of pressurizing receiver 26 at the start of a heating cycle, which traps refrigerant in condenser 24, the heating capacity of a heating cycle is enhanced by connecting the outlet of receiver 26 and the inlet of accumulator 44 in direct fluid flow communication during a heating cycle. Lower pressure in accumulator 44 allows liquid refrigerant in receiver 26 to be directed into accumulator 44, while permitting refrigerant in condenser 24 to drain into receiver 26, to make additional liquid refrigerant available during the heating cycle.

    摘要： 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.
