Abstract:
The invention relates to a cooling system (10) for a transport unit, in particular a refrigerator semi-trailer, a refrigeration trailer or a refrigerated transport container, comprising at least two identically constructed exchangeable refrigeration circuit modules (14, 16, 18) which each contain the refrigerant circuit with the evaporator unit, the condenser unit and the compressor unit. The components are arranged in a frame (12) and comprise a generator with an internal combustion engine (30), a battery (32) and a power electronics (34) as well as a condenser fan (38) and a supply air fan (35) which blow cooled air into the interior of the transport unit.
Abstract:
A refrigerant circuit (21) is configured, which includes an electric compressor (22), a condenser (23), an expansion mechanism (24), an evaporator (25), a hot gas introduction path (123) connecting the electric compressor (22) and the evaporator (25) together, and a switching valve (143) for controlling a flow of refrigerant in the hot gas introduction path (123). In addition, a fan (26) is provided. In a defrosting cycle for introducing refrigerant into the evaporator (25) through the hot gas introduction path (123) to defrost the evaporator (25), if the pressure of the condenser (23) is equal to or lower than a predetermined threshold, the fan (26) forms an air flow from a radiator (45) to the condenser (23).
Abstract:
The invention relates to a reefer container for shipping goods placed on pallets, which container comprises a plurality of sidewalls forming the sides, floor and ceiling in the container, a front end comprising cooling and or ventilating means and a rear end comprising an opening to be closed by one or more doors, a reefer machine further comprising one or more evaporators and one or more fans for transporting cooling air into the container, an evaporator (3) is placed above a fan (2) in an air circulating system for cooling the air (4) in the container(14), where air circulating or passing through the reefer machine (1) and guided from the evaporator (3) is divided into ducts (8) at both sides of the container (14). The invention further relates to a method of loading a reefer container (14) with pallets (15, 16).
Abstract:
A refrigerated container includes a box-like structure having a floor, a pair of opposed side walls, a rear wall, and a roof panel defining an interior volume having an open forward end; and a refrigeration unit disposed in the forward end of the box-like structure and integrated into the box-like structure.
Abstract:
A method for freeze protection for a temperature control system, and a temperature control system for controlling the temperature of a temperature-controlled space (14) at a set point temperature. The method includes monitoring a discharge air (54) temperature, monitoring a return air (50) temperature, setting a target temperature to equal the set point temperature, controlling the return air temperature at the target temperature, and adjusting the target temperature based on the return air temperature when the discharge air temperature drops to one of at or below freezing.
Abstract:
A container refrigeration unit mounted on a container body (1a) includes a casing body (11) partitioning the container into the internal side and the external side thereof. A protruding portion (12) protruding toward the internal side is formed in a lower portion of the casing body (11), and the side stays (50) each extending vertically are mounted on both sides of the rear surface of the protruding portion (12). On the contrary, evaporator frames (40) each located above the protruding portion (12) and extending from the casing body (11) to a top end of the side stay (50) are mounted on both sides of an upper portion of a rear surface in the casing body (11). The bottom tip of the side frame (40) and the top end of the side stay (50) are fixed by a bolt.
Abstract:
A transport refrigeration unit has a front cover that includes a grille supported by and attached to a surround assembly by means of latch members.
Abstract:
A refrigerator unit is provided whose drainage is improved and which prevents ice from being produced by residual water, since a drain pan heater will not hamper the drainage of drain water. It can also improve a defrosting performance by reducing a loss of heat in the drain pan heater and can prevent a heat insulating wall from being thermally deformed. In the refrigerator unit (11) in which a drain pan (20) composed of the heat insulating wall (15) is provided under an evaporator (16), and the drain pan heater (28) is disposed in contact with the surface of the drain pan (20), a thermal conductor (22) is laid on the surface of the drain pan (20) through the intermediary of a heat insulating layer (27), and the drain pan heater (28) is disposed in contact with the surface of the thermal conductor (22).
Abstract:
The invention relates to a cooling unit (1) for a service trolley for use in an aircraft or train. The cooling unit (1) comprises a drawer. The drawer contains a layer of heat-insulating material (29) and one or more Peltier elements (42) located in said layer (29) with a warm side (43) facing the one side of the heat-insulating layer (29) and a cold side (44) facing the other side of the heat-insulating layer (29). First fans (32) are provided on the cold side (44) of the heat-insulating layer (29) and second fans (33) are provided on the warm side (43) of the heat-insulating layer (29). The invention furthermore relates to a service trolley provided with a cooling unit (1) according to the invention as well as to a rack (60) for a multiplicity of cooling units (1) according to the invention. Finally, the invention relates to an aircraft or train containing a cooling unit or service trolley according to the invention.
