Patent ID: 8100632

Claim:
A system for cooling multiple compartments of a turbomachine, the system comprising: a turbomachine comprising multiple compartments, wherein the compartments comprise at least a first compartment and a second compartment; wherein the first compartment encloses at least one turbomachine component, wherein the at least one turbomachine component comprises: a compressor section; a combustion section; or a turbine section; a cooling system for reducing a temperature of each compartment of the multiple compartments; wherein the cooling system comprises: a cooling circuit which is in fluid communication with at least the first compartment and the second compartment; the cooling circuit comprises a first portion the cooling circuit is located within the first compartment and a second portion of the cooling circuit is located within the second compartment; wherein the first portion of the cooling circuit comprises: a first compartment (FC) supply line for allowing the air to enter the first compartment; and a first compartment (FC) discharge line for allowing the air to exit the first compartment; and wherein the second portion of the cooling circuit comprises: a second compartment (SC) supply line; and at least one compartment link for integrating the SC supply line with a discharge end of the first portion of the cooling circuit; and at least one air circulation device for moving a cooling fluid through the cooling circuit; wherein the cooling fluid comprises air which derives from ambient; wherein an air enters the first compartment at a first temperature range, exits the first compartment at a second temperature range and then enters the second compartment at the second temperature range and exits the second compartment at a third temperature range.
