System OptimizationMaximized Effect of Energy-Saving by Combination with V plus centeredMethod of Energy-Saving in case of multiple compressors settingTo respond to the change of used air,3 patterns of optimal capacity control for aircompressor are provided.In case of setting multiple air compressors, install at least 1 unit ofV plus is the key-point to achieve Energy-Saving.3 Patterns of Energy-Saving SystemIn case of installing 1 unit of V plus with variable speed control, it is possible to adjust the capacitywith the V plus. And part of the load operation on the fixed speed type is significantly reduced soas to achieve efficient operation.Daily Consumption of Compressed Air(Example)In case that simple energy-saving operation of 2-3 units is wantedinstead of multi unit controlAutomatic Start/Stop M type Full-LoadOperation, or Stop1 V-M Combination TypeVariable Speed ControlIdeal Energy-Saving Operation by the combination ofV plus and M typeStructure of Compressor System (Example)100%In case that further energy-saving is wanted beside multi unit control,and leveling the operation time of each unit to some extentCapacity AdjustmentType75%2 Single-V Multi-Unit Control SystemMulti unit control system of one V plus and multiple Fixed Speedtype unitsMulti Roller EX50%In case that optimal energy-saving effect and leveled operation timeof each unit are :004:003:002:001:00Leveled operation time and optimal energy-saving operation undermulti unit control of multiple V plusMulti Roller EXV-M Combination Type (JP 3547314) (2-3 units)Air capacity and power consumption of 1 unit of 37kW is displayed as 100%.200Conventional Compressorof Suction ThrottleType 1 unitExplanationU Type1 Power consumption is same featured as 75kW V plus.U Type＊AU Type10075kW050(100)2 Reduction of 25% in initial investment is possible.Air Capacity Adjustment under U Type ControlEnergy-Saving effect is not much＊A: Discharge Air Capacity 0%Power Consumption 140%3 Reduction of power consumption up to 39%, or about 165MWh/year whenthe air consumption rate is 60%.＊ Calculation condition: operation time is 6,000h/year, discharge pressure is 0.6MPa100(200)10025%50075kWV-M CombinationSystem(37kW)Air Consumption Rate(%)V-M CombinationTypeHISCREWHISCREWExample of Energy-Saving EffectPower Consumption Rate(%)Initial Investment(%)Conventional SystemPower Consumption Rate(%)37kW200Power Consumption Rate(%)10:003 Multi-V Multi-Unit Control System0%Explanation All-time operation, all-time capacity adjustment, respondingto the air consumption at all area for power reduction10037kW Air Receiver Tank0100200Full load or automatic stop200ConventionalSuction100 ThrottleControl0100200Air Consumption Rate(%)Air Consumption Rate(%)Single-V3Multi-V Multi-unit Control Type (3-12 units)Multi-UnitControl PanelConventional SystemConventional Compressorof Suction Throttle Type(U Type)Full-Load LockU TypeNo.2U TypeNo.3U TypeNo.4Start/StopPower Consumption Rate(%)300200U Type (WithoutMulti-UnitControl)UUUUUAir Capacity Adjustment under U Type ControlPower reduction is possible, but can NOT reach the samelevel as Single-V.100U0Multi-UnitControl PanelSingle-V（Multi-V）Multi-Unit Control SystemU100U200U300400Air Consumption Rate(%)14Full-Load on＊100＊V＊＊＊＊＊20023004000300All-time operation, all-time capacity adjustment, responding toair consumption at all area for power reduction＊or400Air Consumption Rate(%)17400Power Consumption Rate(%)ororExplanationUU TypeNo.1Multi Roller EX HISCREW HISCREWmulti unit controlorExample of Effect under Single-V Multi Unit Control400Power Consumption Rate(%)20100Full load or automatic stop＊or＊or＊＊200 240300400210270Air Consumption Rate(%)1Multi-Unit Control of Single-V / Multi-V2Fixed Speed Type (M type) under Multi-Unit Control3Suction Throttle Type under Multi-Unit Control4Suction Throttle Type under Parallel Control(without Multi-Unit Control)Air Consumption RateUnit：MWhEnergy-Saving 3195＊ Calculation Condition: 37kW air compressor without built-in air dryer 4 units(Same in efficiency and performance)Operation time is 6,000h/year18
