Inlet Air Cooling for Compressors
- Compressors are designed to operate at specific atmospheric conditions
- 15 Deg C & 60% RH
- De-rating can be as high as 20-25%
- For a given volume mass flow rate will increase with cooler air
- Cooler air is dense and dryer and hence easily compressed
- This results in lower work by the compressor
- Can help reduce 6 to 8% savings in compressor
- GT heat rate may improve y same value
- Reduction in repair and maintenance cost
