Study of Reactive Flow of Split-type Air Conditioners and Inverter Air Conditioners in the Consumer Units and the Public Electricity Companies

Abstract

This paper presents a study about the split-type and inverter air conditioners, in the context of billing and power quality. In field measurements using inverter air conditioners, it was observed that the injected reactive power flow on the bus is equivalent or greater than the consumed active power flow, thus influencing the power factor of the electrical system as these loads are connected to the system on a large scale. The measurements were performed with commercially available power quality analyzers and meters used for billing purposes. Therefore, from the point of view of sales of electricity, such loads are influencing the measurement of the power factor and therefore the reactive power.
