A method of operating a refrigeration system for a refrigerated cargo container includes flowing supply air through a refrigeration unit thereby reducing a temperature of the supply air. The supply air is directed into a mixing chamber and mixed in the mixing chamber until a selected supply air temperature is achieved. The supply air is directed through a refrigeration system outlet and into an interior of a cargo container.

Abstract: A cooling chamber for drawing down freshly picked and field warmed unitized (for example in cartons stacked on pallets) vegetables, such as cauliflower, is disclosed. Freshly picked cauliflower is placed in rectangular cartons in side-by-side stacks of four extending approximately fourteen cartons high. A group of individual pallets (typically 10 to 12) so loaded are typically placed in the field on a transport chassis and brought to the vicinity of the cooling chamber where they are simultaneously unloaded by a multi-pallet forklift truck. The chamber receives multi-pallet load through an open door and is inserted into the chamber. This chamber has a rear seal which conforms to the periphery of the load and defines in the interstitial volume between the chamber backwall and load a warm air return plenum to forced draft refrigeration apparatus. The load when placed within the chamber has a door closed to form an air-tight seal.
