Ice Turboost.

Typically, Gas Turbine power output decreases by 1% when the air temperature increases by 1°C.
On hot summer days (which correspond to peak periods in countries where the air-conditioning market is well developed) gas turbine power output is at a minimum. Inlet Air Cooling is therefore often used to increase the power output of the Gas Turbine during these peak periods.
For such applications, Ice Containers are dry-stacked in large atmospheric tanks made of steel or concrete and located upstream of the Gas Turbine filters.
For charging (off-peak periods), the Gas Turbine is not used. The water glycol coolant - cooled by a chiller to below 0°C (32°F) - flows around containers, making ice inside.
For discharging (peak periods), the Gas Turbine is used. The inlet air sucked by the compressor of the Gas Turbine flows directly through the ice containers, melting the ice inside.
