Why does the increased intake air temperature increase the power consumption of a reciprocating compressor?
The temperature rise is inversely proportional to air density. i.e., the density of air reduces as the temperature rises. For a given amount of air, a decrease in density causes an increase in volume, implying that air takes up more space. Every compression stroke of a reciprocating compressor displaces a fixed volume of air. Because of the decrease in density and a fixed volume of a cylinder, the compressor requires a greater number of strokes to reach the predetermined pressure level in the receiver tank. Thus, power consumption increases.
