Integrated electronic refrigerant management system

摘要

A process and method for monitoring and selectively controlling the capacity and power demand within a transport unit is disclosed. Specifically, the present invention teaches the combined controls of an electronic suction modulation valve (130), and electronic expansion valve (144), and/or an electronic hot gas valve (120) in communication with a microcontroller (156) and a number of sensors in order to monitor and control power consumption and capacity, preferably without the use or presence of compressor unloaders, mechanical throttling devices, or other mechanical power control devices. <IMAGE>
