The Influence of Reactive Power on Energy Efficiency in Household Applications

摘要

In this paper a look at reactive power on energy efficiency of air conditioning and electric lighting in household applications is taken. Usualy in energy efficiency only efficiency η as sign of active power consumption is treated. Through examples with airconditioner of inverter type and electric energy saving lighting non neglecting consumption of reactive (nonactive) power is presented. The measurements are realized by virtual instrument for power quality monitoring based on NI LabVIEW™ platform. It generally means that exept benefets of power electronics using for adjustable speed drives and energy saving lighting, new problems are generating in the producing, transfering, distributing and using of electric energy.
