RESUMO:

VRF, or Variable Refrigerant Flow, is one of the greatest technological innovations in ambient air conditioning. The equipment that works with this technology has high energy efficiency, thanks to the constructive characteristics of the system, as well as having several resources that aim to guarantee the maximum possible reliability of the system, be it in automation, remote management or the possibility of installing renovators of Air in order to ensure the highest quality of air in the environment. This system also has multiple electronic controllers, which seek from smoothing the startup of the machine to correct control of thermal demand. However, the equipment with VRF technology, because they are non-linear loads, raise several concerns about quality problems Of the electric energy that the electric grid that feed them. Among them are harmonic distortion and voltage and current imbalances. In order to be able to visualize them, as well as the means to attenuate them, several implementations are made in software chosen for this purpose, including the processing of voltage and current signals. Several electrical installations of several buildings of the campus are also compared. UFRN, some equipped with air conditioning systems with VRF technology and others with conventional air conditioning systems, in order to illustrate the energy efficiency of each building. Projections are made for the replacement of conventional systems by the VRF systems in these buildings, in addition to comparisons that allow to present the elevation of the energy efficiency in these buildings.
