Ordinary screw compressors can regulate the motor's rotation speed through external inverters to regulate the air discharge volume in order that air volume produced matches that of used and hence achieves energy efficiency. However ordinary screw air compressors are built with motors with mains rated rotating speed, rated power and rated efficiency, whereas external inverters would force the air compressor's motor to deviate from its mains rated rotating speed. Once the ordinary motor deviates from its mains rated rotating speed, its efficiency will be reduced significantly, and the greater the deviation the more significantly the efficiency will be declined. Withing all its rotating speed range, the BMVF variable frequency screw air compressor is able to maintain extremely high motor efficiency, thus giving it superior energy-saving effect over ordinary screw air compressor with external inverter. In addition, the regulation range of external inverters for ordinary screw compressor is from 40% to 100%. In other words, when
the working condition deviates in excess of 60%, the external inverter will not be able to regulate the motor's rotating speed. In contrast, Kaishan Compressor's BMVF variable frequency air compressor has a operating speed range of 20-100%, which means that even in the case of 80% deviation from working conditions, Kaishan Compressor's BMVF variable frequency air compressor can still function efficiently.
Table of Comparison for Energy Efficiency of 37kW screw air compressor
Kaishan BMVF variable frequency screw compressor Annual power consumption: 183.520kW.
Ordinary mains frequency screw compressor Annual power consumption: 281,200kW.
Ordinary variable frequency screw compressor Annual power consumption: 201,280kW.
Screw air compressor with inverter Annual power consumption: 236,800kW.
Take 37kW screw air compressor as an example, all efficiency values were recorded during experiamental tested and the annual power usage calculation were based on average operating time of 8,000 hours per annum: Kaishan BMVF screw air compressor compared with external variable frequency inverter screw air compressor.
Energy-saving per annum: 236,800-183,520=53,280 kW.
