In a reciprocating compressor, the capacity depends on the volume displaced by the piston during its movement. To calculate adiabatic head and power we use equation below. STEP 4 : calculate the actual power requirement. The kW output of your compressor motor is divided by the electrical efficiency to give the electrical input power that your compressor uses. Convert 10 hp to kW: P (kW) = 0.746 ⋅ 10hp = 7.460 kW . So, we get the following results: compressor throughput is 92.6 m 3 /min, consumed power is 91.3 kW Problem 3. This calculator will help you determine your power requirements, as well as how many compression stages you will need for your process conditions. II. Anyone can produce a customize-able template from day 1, and also it can save you a present spreadsheet as a general template, and then fix it right up a fabulous bit. With this blog entry I am also attaching an excel workbook which provides some design equations for calculating the shaft power of oil-free or dry screw compressors. A mapping approach was taken to evaluate the A/C compressor power consumption, where the vehicle was tested in different ambient conditions (15 °, 25 °, and 35 °C) and at different speeds. The higher the capacity the more power is consumed. The objective of compressed air energy-savings projects is to reduce the kWh consumed by the electric motors powering your air compressors. Calculation with line to neutral voltage. You can see the numbers vary, but the common ground is specific power. Lets calculate the power consumed by a 1.5 ton 5 star rated split a/c operated for 10hrs. Number of Units consumed = (1172/ 1000) kW x 10 hrs =11.72 units (kWh) Adiabatic head and centrifugal compressor power calculation.
