COMPRESSED AIR SYSTEM

Rating:

Description


The compressed air system sizing calculation involves calculating the compressor FAD (free air delivery), selecting the compressor, determining the size of the receiver, and calculating the condensation quantity. The FAD calculation involves determining the selected flow, temperature, reference pressure, and compressor. The receiver sizing calculation involves determining the compressor capacity, inlet pressure, maximum temperature, cycle frequency, pressure difference, outlet temperature, and minimum volume. Intermittent output receiver sizing involves determining air flow requirement, time of emptying phase, permitted pressure drop, receiver volume, and selecting receiver volume. Condensation quantity involves determining relative humidity, the amount of water the air can carry at ambient, and the maximum water quantity.
