Abstract
According to an aspect of the invention, a method for ventilating a turbine compartment is provided, the method comprising directing an air flow from an air intake to a first air conduit, transferring a first heat between the air flow and a first fluid within a heat exchange apparatus and pumping the first fluid through a fluid circuit in fluid communication with the heat exchange apparatus, wherein a portion of the fluid circuit is located underground. The method further includes transferring a second heat between the first fluid and a surrounding ground and directing a conditioned air flow from the heat exchange apparatus to a turbine compartment via a second air conduit.

A system for turbine compartment ventilation, the system comprising:
- a first air conduit in fluid communication with a heat exchange apparatus, the first air conduit configured to direct an air flow at a first temperature from an air intake to the heat exchange apparatus;
- a fluid circuit in fluid communication with the heat exchange apparatus, wherein a portion of the fluid circuit is located underground;
- a pump located in the fluid circuit configured to flow a first fluid through the fluid circuit to transfer a first heat between the first fluid and a heat sink;
- and
- a second air conduit in fluid communication with the heat exchange apparatus and in fluid communication with a turbine compartment, the second air conduit configured to direct the air flow at a second temperature from the heat exchange apparatus to the turbine compartment.
A power generation system, comprising:
- a turbine compartment containing a gas turbine;
- an air conduit in fluid communication with the turbine compartment, the air conduit configured to receive an air flow from the ambient environment, direct the air flow through a coil and direct a conditioned air flow from the coil to the turbine compartment;
- a fluid circuit in fluid communication with a heat exchanger, wherein a portion of the fluid circuit is located in a heat sink and a first fluid flows through the fluid circuit to transfer a first heat between the first fluid and the heat sink;
- and
- an intermediate circuit in fluid communication with the coil and heat exchanger, wherein a second fluid is configured to flow through the intermediate circuit to transfer a second heat between the received ambient air flow and the first fluid.
