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 multi-compartment transport refrigeration system includes a heat rejecting heat exchanger downstream of a compressor discharge port; a first evaporator expansion device downstream of the heat rejecting heat exchanger; a first evaporator having an first evaporator inlet coupled to the first evaporator expansion device and a first evaporator outlet coupled to the compressor inlet path, the first evaporator for cooling a first compartment; a second evaporator expansion device downstream of the heat rejecting heat exchanger; a second evaporator having a second evaporator inlet coupled to the second evaporator expansion device and a second evaporator outlet coupled to the compressor inlet path, the second evaporator for cooling a second compartment; and a first evaporator outlet isolation valve positioned in an outlet of the first evaporator, the first evaporator outlet isolation valve to prevent migration of refrigerant from the second evaporator outlet to the first evaporator outlet.
