Abstract:
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.
Abstract:
The status of a transport refrigeration unit and the load therein is established on a real time and batch time basis by continuously transmitting the cargo temperature or reefer return temperature, and determining conditions such as loading and unloading, open doors, waiting times, etc. This allows apportioning costs between the operator of the transport and the consignee of the cargo.
Abstract:
A refrigeration system for a transport refrigeration unit and a method of operating the refrigeration system for cooling a temperature controlled cargo space are disclosed. The refrigeration system includes a primary refrigerant circuit including a refrigerant compression device, a motor for driving the compression device; a variable speed drive for varying the speed of operation of the compression device; and a controller operatively associated with the variable speed drive and the compression device. The controller controls the cooling capacity of the refrigeration system by selectively controlling the speed of said compression device in a first continuous run mode of operation and by selectively powering on and powering off said compression device in a first cycling mode of operation.
Abstract:
An automated and/or remote method for identifying and/or changing the source of power for these generator sets, which may apply to any environment where there are alternative sources of power available which must be managed remotely (such as for other powered containers not used for refrigeration transport).
Abstract:
A temperature control system for a vehicle that defines a load space for supporting cargo. The temperature control system includes a refrigeration unit that has a refrigeration circuit, and a heating system that has a heating circuit. The refrigeration circuit includes a prime mover and a cooling coil that selectively cools an airflow entering the load space. The heating circuit includes a pump that circulates a coolant fluid through the heating circuit, a dedicated heater that heats the coolant fluid, and a heating coil that selectively heats the airflow entering the load space. The temperature control system also includes a controller that detects conditions of the load space, and that engages one of the refrigeration unit and the heating system to condition the load space in response to the detected conditions.
