Patent ID: 8534044

Claim:
A thermal management system for a gas turbine powerplant having a first supply line for introducing a first operating fluid to a first powerplant subsystem and a second supply line for introducing a second operating fluid to a first a second powerplant subsystem, the thermal management system including a heat transfer control module comprising: a reversible heat pump including a working fluid line having therein a heat pump compressor for circulating working fluid in forward and reverse directions through said fluid line and an expansion valve for expanding working fluid passing therethrough; a first heat exchanger having a first heat exchange path for the working fluid between said compressor and said expansion valve and a second heat exchange path included in the first supply line, wherein said first and second heat exchange paths permit heat to he exchanged between fluids therein; and a second heat exchanger having a first heat exchange path for the working fluid between said compressor and said expansion valve and a second heat exchange path included in the second supply line, wherein said first and second heat exchange paths permit heat to be exchanged between fluids therein.
