Abstract: A refrigeration system comprised of a walled insulated enclosure is provided with a drive motor having a drive shaft extending therefrom. The drive shaft and drive motor are positioned along the ceiling of the walled enclosure. The drive shaft terminates at a coupling mechanism. A complimentary coupling mechanism is attached to the top of a well-known movable food rack. Thus, when the food rack is stored within the walled enclosure, the coupling mechanism on the food rack mates with and attaches to the complimentary coupling mechanism of the drive shaft. When the drive motor is actuated, the drive shaft will rotate the movable food rack. It will be appreciated that by rotating the movable food rack, the present invention will permit the food stored on the food rack to chill far more quickly than if the food rack were to remain stationary. In addition, by rotating the food rack, the present invention eliminates warm air pockets which allow bacterial growth.

Abstract: A method and apparatus for air conditioning parked aircraft is disclosed in which air at a temperature below the freezing point of water is provided under pressure to the aircraft. The use of sub-freezing air enables a reduction in air flow rate over prior art systems. This results in less power consumption for cooling and pressurizing the air and also results in less cabin noise. Further, the air entering the cabin is very low in humidity, which enhances passenger comfort. Several cooling system mechanizations are presented which include provisions for automatic frost removal.

Abstract: A temperature control means which is suitable for use with small, transferable refrigerated containers is described.

Abstract: A heater/cooler unit specially adapted for motels, hotels, hospitals and like structures enables adjacent rooms to be cooled or heated by using certain commonly shared components. An evaporator is disposed in each of two adjacent rooms. The evaporators are connected to a common compressor and condenser disposed outside the rooms. Appropriate control mechanisms are provided to enable the evaporators to operate independently. The components are disposed in a housing which forms a portion of the exterior wall of the structure and a portion of the common wall of the rooms. Certain of the components can be placed atop a cart which can be wheeled into and out of the housing so as to facilitate installation and servicing of the unit. Electrical strip heaters can be added to the evaporators to provide a heating capability. An alternative embodiment employs interior and exterior heat exchangers operated as heat pumps.

The cooling elements are independent at the respective containers to individually control the temperatures of the containers.

Abstract: Apparatus and the method for directing cool air to stacks of containers holding freshly harvested produce and the like, to remove field heat therefrom. Air is caused to flow in one direction through the containers to cool the produce, then the airflow direction is reversed and the air is caused to flow in the opposite direction. In this way, the produce in the container is uinformly cooled. The apparatus includes a housing having a suction fan for blowing air through an air cooler into a plenum from which the cool air passes through the containers. The direction of airflow is selected by moving damper devices relative to the housing.

Abstract: The aircraft pre-ventilation system has a ventilation unit mounted for movement along the ground. A primary and a return duct carry air between the ventilator and the aircraft door opening. The ducts are connected to a fitting which is designed to fit into and seal different size door openings for different aircraft. The fitting has a central rigid member, and a flexible bladder is attached to and surrounds the outside of the central member. The fitting is supporting by an adjustable arm for positioning the fitting in the door opening.

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.

A ducting system from the air entry connects the purifying means, cooling means, dehumidifying means and heating means to an air exit. Fan means in the unit circulate air in the ducting system from the air entry to the air outlet, and the removable flexible conduits connect the air entry and the air exit to the enclosed space.

Abstract: The icing apparatus comprises an open frame structure for receiving cartons stacked in rows and columns on a pallet. These cartons contain perishable food such as broccoli brought in from the field and are to be treated with liquid ice to preserve their contents. Towards this end, the apparatus includes left and right carriages carrying horizontal rows of liquid ice injecting probes or nozzles. These carriages can move up and down left and right sides of the frame and also the probes themselves can be moved in and out towards and away from cartons on the pallet. By this arrangement, an upper horizontal row of cartons can be simultaneously iced by the horizontal row of probes by simply moving the same into the hand hold openings of the cartons. The carriage structures can then be lowered by the heighth dimension of the cartons and a next horizontal row of cartons simultaneously treated with liquid ice.

Abstract: This invention relates to a panel air chiller for use with a portable food storage unit. The panel air chiller includes in combination first and second spaced apart parallel panels that have thermal insulation disposed between and in contact with the panels. The thermal insulation material has formed therein at least a first and a second chamber between the panels thereby establishing passageways between the panels and through the thermal insulation material. Located in the first chamber is a means to extract heat from air passing thereover to thereby cool the air. At least one return air opening is provided through one of the panels to communicate with the portable storage unit. A fan is coupled to the space between the panels and to the first chamber to thereby draw air through the return air opening coupled to the portable storage unit.

Abstract: A freezing unit for use in a cold chamber to effect freezing of a load of pre-cooked food packages at a rate more rapid than the freezing rate of that load that would take place in the chamber in the absence of the unit. The unit includes a vertical plenum provided with a perforated wall and having an open input and a closeable output. The food packages are stacked in a rack adjacent the perforated wall of the plenum, with air spaces between the packages. Cold air drawn from the chamber atmosphere at a temperature below the freezing point of the food is forced into the input of the plenum to produce a positive pressure therein when the output is closed, thereby causing the pressurized cold air to penetrate the perforated plenum wall and pass through the air spaces in the stack at high velocity, the air returning to the cold chamber whereby rapid cooling of the packages is effected.
