Abstract

A heating and cooling system for inlet air of a turbine compressor. The heating and cooling system may include a thermal energy storage tank charging loop, a cooling loop in communication with the thermal energy storage charging loop, and a heating loop in communication with the cooling loop and the inlet air of the turbine compressor.

First claim

We claim:

1. A heating and cooling system for inlet air of a gas turbine compressor, comprising:
one or more water chillers comprising an evaporator and a condenser;
a thermal energy storage tank charging loop comprising the evaporator of the one or more water chillers;
a cooling loop comprising the condenser of the one or more water chillers, wherein the cooling loop is in communication with the thermal energy storage tank charging loop via the one or more water chillers; and
a heating loop in communication with the cooling loop via a heat exchanger such that waste heat from the condenser of the one or more water chillers is exchanged in the heat exchanger to the heat loop, wherein the heating loop is in communication with the inlet air of the turbine compressor.

2. The heating and cooling system for inlet air of claim 1 , wherein the heating loop comprises a fluid coil positioned about the gas turbine compressor and in communication with the inlet air.

3. The heating and cooling system for inlet air of claim 1 , wherein the cooling loop comprises a cooling tower.

4. The heating and cooling system for inlet air of claim 1 , wherein the thermal energy storage tank charging loop comprises a thermal energy storage tank.

5. A method of operating an inlet air heating and cooling system for a compressor inlet as a heat pump, comprising:
operating a chiller to charge a thermal energy storage tank;
directing waste heat from the chiller to a heat exchanger;
heating a fluid in communication with the compressor inlet and the waste heat of the chiller in the heat exchanger; and
heating the inlet air about the compressor with the waste heat of the chiller.

6. The method of claim 5 , wherein the step of operating a chiller to charge a thermal energy storage tank comprises circulating a fluid about a chiller evaporator and a thermal energy storage tank.

7. The method of claim 5 , wherein the step of directing waste heat from the chiller to a heat exchanger comprises circulating a fluid about a chiller condenser and a heat recovery heat exchanger.

8. The method of claim 7 , wherein the step of heating a fluid in communication with the compressor inlet with the waste heat of the chiller in a heat exchanger comprises heating the fluid in the heat recovery heat exchanger.

9. The method of claim 5 , wherein the step of heating the inlet air about the compressor with the waste heat of the chiller comprises heating the inlet air via a fluid coil.

10. A heating and cooling system for inlet air of a gas turbine compressor, comprising:
a thermal energy storage tank charging loop with a thermal energy storage tank and a chiller evaporator;
a cooling loop in communication with the thermal energy storage tank charging loop;
the cooling loop comprising a chiller condenser and a heat recovery heat exchanger;
a heating loop in communication with the cooling loop and the inlet air of the gas turbine compressor; and
the heating loop comprising a fluid coil positioned about the turbine compressor and in communication with the heat recovery heat exchanger.

11. The heating and cooling system for inlet air of claim 10 , wherein the cooling loop comprises a cooling tower.

12. The heating and cooling system for inlet air of claim 10 , wherein the thermal energy storage tank charging loop comprises a primary water pump.

13. The heating and cooling system for inlet air of claim 10 , wherein the cooling loop comprises a secondary water pump.

14. The heating and cooling system for inlet air of claim 10 , wherein the heating loop comprises a condenser water pump.
