Patent number: 6615908Abstract: The invention allows cool rooms or sea containers designed for frozen goods to handle produce requiring more precisely controlled temperatures and conditions, e.g., vegetables and fruits requiring temperatures in the chilling range and often also needing control or modification of the atmosphere. Each load of produce (100) (e.g. of pallet size) is held in the sea container or cool room but is sealed from the air of the refrigerated environment by, for example, a plastics bag (56). The atmosphere within the bag is then circulated by a fan (12) (or by convection currents from a heating element) so as to pass through the load and around it via ducts (30) provided adjacent the bag (56). Heat exchange (50) between the circulating gas and the refrigerated environment, via the plastics film, serves to cool the load. However, if cooling is excessive a heating element can be used to raise the temperature of the circulating atmosphere. Gas composition of the atmosphere can be controlled by scrubbing, flushing, etc.Type: GrantFiled: July 24, 2000Date of Patent: September 9, 2003Assignee: Transphere Systems LimitedInventors: Paul Raymond Bosher, Robert Barnes

Patent number: 6330909Abstract: In a vehicle air-conditioning system, an evaporator is disposed in an air-conditioning case to form a bypass passage through which air bypasses the evaporator, and an opening degree of the bypass passage is adjusted by a bypass door. When a vehicle engine operates, the system performs a cold-storing mode where cold quantity stored in condensed water on the evaporator is increased. On the other hand, when operation of the vehicle engine is stopped, the system performs a cold-releasing mode where air passing through the evaporator is cooled by cold released from frozen condensed water. During the cold-storing mode and the cold-releasing mode, temperature of air blown into a passenger compartment can be adjusted by adjusting the opening degree of the bypass passage. Thus, in the vehicle air-conditioning system, cold-storing quantity in the evaporator can be improved while power-saving effect of the vehicle engine is improved.Type: GrantFiled: October 20, 1999Date of Patent: December 18, 2001Assignee: Denso CorporationInventors: Koji Takahashi, Yuichi Shirota, Koichi Ban, Hikaru Sugi, Yasuhiko Niimi, Hiroshi Kishita, Yasushi Yamanaka, Masayoshi Naka

Publication number: 20010027663Abstract: A modular air conditioning system comprises a self-contained refrigeration power cell and a remotely located heat exchanger coupled by a low-pressure refrigerant circuit. The refrigeration power cell comprises a compressor, a condenser, an expansion device, and an evaporator, which are serially coupled to form a high-pressure closed refrigeration circuit. The low-pressure circuit thermally interfaces with the condenser to remove heat from the high-pressure circuit. This heat exchanger is adapted to mount in proximity to or be integrated with the radiator. Alternatively, this circuit thermally interfaces with the evaporator to remove heat from the low-pressure refrigerant. This heat exchanger is adapted to mount in the cabin of the vehicle. When the low-pressure circuit thermally interfaces with the evaporator, the low-pressure circuit may further include a cool box for storing items to be refrigerated. Preferably, the cool box and heat exchanger may each be operated either alone, or in combination.Type: ApplicationFiled: June 18, 2001Publication date: October 11, 2001Applicant: Bergstrom, Inc.Inventors: Terry A. Zeigler, William David Gavin, Phillip Carew Evans

Patent number: 6276161Abstract: A modular air conditioning system comprises a self-contained refrigeration power cell, a heat exchanger remotely located from the refrigeration power cell, and a low pressure refrigerant communication circuit operably coupling the refrigeration power cell to the heat exchanger. The refrigeration power cell comprises a compressor, a condenser, an expansion device, and an evaporator which are serially coupled to form a high pressure closed refrigeration circuit. A drive mechanism, such as an electric or hydraulic motor, or conventional belt, is coupled to the compressor. The low pressure refrigerant communication circuit thermally interfaces with the condenser to remove heat from the high pressure closed refrigeration circuit. Alternatively, this circuit thermally interfaces with the evaporator to remove heat from the low pressure refrigerant. This heat exchanger is adapted to mount in the cabin of an over-the-road or off-road vehicle.Type: GrantFiled: December 20, 1999Date of Patent: August 21, 2001Assignee: Bergstrom, Inc.Inventors: Larry Peiffer, Terry Zeigler, William G.

Patent number: 6016664Abstract: A refrigerated freight container (1) includes a heat insulated, substantially parallelepipedial case with a ceiling (2), two side walls and two end walls (5,6), and a bottom (7). A refrigerating unit with an ice bin (10) is positioned in the corner between one of the end walls (5) and the ceiling (2). Around the ice bin (10) are flow channels (12) for refrigerating air disposed, whereby the flow of the refrigerating air is achieved by fans. An inner ceiling (14) is disposed against the container ceiling (2) with a spacing therebetween, and this spacing constitutes a flow path for the refrigerating air from the refrigerating unit. The inner ceiling (14) ends at a distance from the inside of the side walls and end wall (6), which is opposite to the one where the refrigerating unit is positioned.Type: GrantFiled: July 9, 1998Date of Patent: January 25, 2000Assignee: Frigotainer Insulated Air Cargo Containers ABInventors: Nils Larsson, Goran Westerholm

Patent number: 5916256Abstract: A refrigerating system of freight containers comprises an ice bin, against the wall of which the air to be refrigerated is caused to flow by way of a flow duct. At least one fan is provided for generating said flow and is thereby located above the lowermost level of the ice bin. At least a portion of the flow duct is formed by an interspace between a wall of the ice bin and a screen and between the screen and an insulated wall constitutuing an inner wall of the freight container and extending downwards from the fan or fans towards the lowermost level of the ice bin and then upwards past said wall of the ice bin.Type: GrantFiled: June 24, 1998Date of Patent: June 29, 1999Assignee: Frigotainer Insulated Air Cargo Containers ABInventors: Goran Westerholm, Nils Larsson
