Applications
of AARP - Gas Turbine Inlet Air Cooling
It is well known that output and efficiency of Gas Turbines
is highly sensitive to inlet combustion air temperature.
Following are typical outputs and efficiencies.

Various methods are, therefore, used for cooling inlet air
temperatures e.g.
1) Water fog based evaporative Cooling.
2) Water cooled LiBr Absorption Chiller based
Cooling.
3) Air cooled AARP based Cooling.
It reduces net CO2 emissions.
In areas where water is not available, air cooled AARP
working on exhaust heat of Gas turbine is an automatic choice
and an ideal solution for gas turbine inlet air cooling.
