20080231239 | Generator Set with Dual Mounting Capability - A generator set is provided with both a pin-on mount mechanism and a clamp-on mount mechanism for mounting the generator set to a container. Both the pin-on mount mechanism and the clamp-on mount mechanism are selectively positionable in either a deployed for use position or a stowed position. When the clamp-on mount mechanism is in the deployed for use position, the pin-on mount mechanism is positioned in a stowed position. When the pin-on mount mechanism is in the deployed for use position, the clamp-on mount mechanism is positioned in the stowed position. | 09-25-2008 |
20090211287 | MODULAR CONDENSER FAN ASSEMBLY - A modular condenser fan/motor assembly for use in a transport refrigeration system includes a support frame, a fan shroud panel, a fan/motor assembly and a support bracket. A fan and motor assembly for use in a transport refrigeration unit includes a fan impeller disposed about an inside/out motor, whereby the fan impeller rotates with at least a portion of an outer casing of the motor. | 08-27-2009 |
20090211288 | COMBINATION MICROCHANNEL CONDENSER AND RADIATOR MOUNTING ARRANGEMENT - A transport refrigeration system includes a single frame for containing both a refrigeration condenser coil and an engine coolant radiator arranged in serial airflow relationship within a framework. Either one or the other may be removed and replaced without replacing the other. | 08-27-2009 |
20100289273 | TWO SPEED CONTROL FOR MOBILE REFRIGERATION GENERATORS - A current sensor is installed in a generator set to measure the current being delivered from the generator set to a refrigeration unit. A control is responsive to the current transformer to reduce the speed of the drive engine to a lower speed when the current being delivered to the refrigeration unit is determined to be below a predetermined higher level. Provision is made to override the system when the sensed current is determined to be transient caused or in the event that ambient temperature is determined to be above a predetermined temperature threshold. | 11-18-2010 |
20110088411 | Start-Up Control for Refrigeration System - A transport refrigeration system has an engine driving an electric generator. A compressor is powered by the generator. At least one first electric fan is positioned to drive an airflow across a heat rejection heat exchanger. At least one second electric fan is positioned to drive an airflow across a heat absorption heat exchanger. A controller is coupled to the compressor and first and second fans. The controller is configured to: start the engine; engage the generator and at least one of the first fans before the engine has reached running speed; after the engine has reached running speed, start the compressor; and after starting the compressor, start at least one of the second fans. | 04-21-2011 |
20110094297 | METHOD FOR DETERMINING AIR FILTER CONDITION - A sensor that is designed for determining ambient pressure for purposes of derating an internal combustion engine at high altitudes, is used to determine the condition of the air filter by taking pressure measurements in the intake manifold before and after the engine is started, with the difference then being an indication of the condition of the air filter. | 04-28-2011 |

20140250941 | Transport Refrigeration System With Engine Exhaust Cooling - A heat exchanger includes an inner tube extending along a central axis, an array of a plurality of heat transfer members mounted to the inner tube, and a plurality of outer tubes disposed radially outward of and in parallel relationship to the inner tube, the inner and outer tubes extending longitudinally to pass through the array of heat transfer members. The heat exchanger is particularly suited for use as an engine exhaust cooler in connection with a transport refrigeration unit, wherein the inner tube defines an internal flow passage through which engine exhaust gas passes, each outer tube defines an internal flow passage through which refrigerant passes, and the plurality of flow passages between adjacent heat transfer members defines an air flow passage. In an embodiment, the heat transfer members may be annular disks having an internal chamber filled with air or other heat transfer working fluid. | 09-11-2014 |
