Sample calculation of energy saving:
For example a standard 55kW screw compressor delivers air at 70% loading and operates 5800 hours per years. Taking electricity cost of USD 0.15/kWH, the additional energy consumed as comparing with VSD compressor will be:
A. Energy consumed during unload operation assuming unload shaft power absorbed is 45% of full load amount: 30% unload times x loss during unload time = (45% x 55kW) x 5800 hour/year x USD 0.15 = USD 6,460/year.
B. Energy consumed due to cut-in/cut-out pressure band of 2 bar.g assuming this counts for 14% of full load amount: 70% loading time x additional 2 bar.g of differential pressure loss = (14% x 55kW) x 5800 hour/year x USD 0.15 = USD 4,689/year.
Total energy saved by using VSD compressor will be = USD 6,460/year + USD 4,689/year = USD 11,149/year.
In a conclusion, a VSD compressor can save annually the electricity cost of USD 11,149, 3 years can then save USD 11,149 x 3 = USD 33,447 which could be more than capital investment for purchasing another VSD compressor.
