The present invention relates to apparatus, systems, and methods of managing large quantities of low-grade waste heat energy by generating excess electrical power via an ORC process driven by the removal and recovery of waste heat under favorable operating conditions, and utilizing the same apparatus to provide waste heat removal via a refrigeration process that consumes electrical 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.
