The Compressed Air Energy Equation
So, let''s do the math. The one-horsepower air motor outputs about 0.75 kW of shaft power. To produce this power: A lossless compressor must consume about 7.5 kW (30 x 25/100 = 7.5 kW) Leaks increase the power required to 9.75 kW (7.5 kW x 1.3= 9.75 kW). Overcoming pressure drop increases the power further to 10.5 kW (9.75 x …

How much electricity (kWh and kW) does an air conditioner use?
If a 5000 BTU air conditioner is left on for 8 hours a day, it would use between 60 and 100 kWh of energy each month. In comparison, a 36000 BTU (3 Ton) central air conditioner uses – on average – between 1.5 and 2.8 kWh of energy per hour. If an air conditioner of this size is left on for 8 hours a day, it would use between 360 and …
Modeling and Simulation of Air Compressor Energy Use
C = 265 scfm x 47% = 125 cfm. If the average demand in the plant were reduced by 70 scfm, the average air demand would be reduced to 55 scfm. Substituting into Equation 3, the expected fraction of rated capacity, FC, at which the compressor would then operate would be about: FC = 55 cfm / 265 cfm = 21%.
How Much Power Does A 2Hp Air Compressor Use?
Typically, a 2HP air compressor would require a higher voltage, such as 240V, and a certain amount of current, usually specified in amps.
