ABSTRACT:
A system and process for optimizing the power drawn on a transport refrigeration system under power limitation conditions is disclosed. The invention includes a microprocessor control which adjusts the desired superheat level for the system, thereby altering the expansion valve, thereby limiting the mass flow rate of refrigerant through the system without having a comparable drop in refrigeration capacity as would a similar actuation of the suction modulation valve.
