Abstract

See full text

The present invention relates to apparatus, systems, and methods of managing large quantities of low-grade waste heat energy by 1) generating excess electric power via an ORC process driven by the removal and recovery of waste heat under favorable operating conditions, and 2) utilizing the same apparatus to provide waste heat removal via a refrigeration process that consumes electric power when environmental conditions do not permit operation in the ORC mode. The mode of operation of the system is principally determined by the thermal energy of the waste heat stream and the availability, or lack thereof, of adequate cooling resources. Such resources are often subject to local environmental conditions, particularly ambient temperature which varies on a diurnal and annual basis.
