Refrigerated transport system

摘要

A refrigerated transport system has a container, a generator system, and a refrigeration system. The refrigeration system is electrically coupled to the generator to receive electric power and thermally coupled to the container. The refrigeration system includes an electrically powered compressor. A condenser is downstream of the compressor along a refrigerant flowpath. An expansión device is downstream of the compressor along the refrigerant flowpath. An evaporator is downstream of the expansión device along the refrigerant flowpath. A controller is coupled to the expansión device to control operation of the expansión device. The controller is configured to opérate the expansión device to control an evaporator superheat. The evaporator superheat is to be relatively high for a set temperature of a first valué associated with non-frozen perishables. The evaporator superheat is to be relatively low for a second valué of the temperature associated with frozen goods and subject to maintenance of a minimum suction superheat.
