Patent ID: 7984606

Claim:
A thermal management system for a gas turbine powerplant having a first supply line for supplying to the powerplant a first operating fluid comprising a lubricant and a second supply line for supplying to the powerplant a second operating fluid comprising a powerplant fuel, the 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, wherein the working fluid is not the lubricant or the fuel; a first heat exchanger having a first heat exchange path for circulating 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 be exchanged between fluids therein; and a second heat exchanger having a first heat exchange path for circulating 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.
