摘要： An apparatus and method are disclosed for terminating a refrigeration unit's defrost function. The refrigeration unit comprises an evaporator, a temperature sensor to measure the temperature of the evaporator during a defrost function, and a controller configured to calculate the rate of temperature change and terminate the defrost function when the rate meets a specified criteria, such as a predetermined rate or a sharp increase in the rate after the evaporator temperature has increased above the freezing point of water.

摘要： A method for controlling the operation of a transport refrigeration system to limit current drawn by a compressor powered by AC electric current includes the steps of: (a) determining whether an ambient temperature in which the refrigeration unit is operating has been greater than a set point ambient temperature for a first time period; (b) determining whether the refrigeration unit has been operating in a temperature pulldown mode; (c) determining whether the AC electric current is equal to or exceeds a preset maximum current limit; (d) determining whether a time period between a last defrost cycle and a next previous defrost cycle is less than fifteen minutes; and (e) if the determination is YES in both of step (a) and step (b) and is also YES in at least one of step (c) and step (d), reducing the preset maximum current limit to a reset maximum current limit.

摘要： 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.

摘要： A heat exchanger (28 includes a first manifold (34), a second manifold (36) and a plurality of parallel heat transfer tubes (38). The first manifold (34) includes one or more manifold sections (58, 60, 63). A first one of the manifold sections (58) is connected to an inlet (64). The heat transfer tubes (38) extend between and fluidly connect the first and the second manifolds (34, 36). At least some of the heat transfer tubes (38) are disposed with the first manifold section (58).

摘要： A tool is provided for maintaining the position of a fan during periods in which the retaining nut is applied or removed from the electric motor drive shaft. The tool includes a central portion with an opening to fit over the nut and to act as a fulcrum for the tool. Extending radially outward from each side of the central portion is a torque member that fits against the respective blades to hold them in place during rotation of the nut.
