Análise do consumo e qualidade de energia em condicionadores de ar convencional e inverter

Abstract

The option for an air conditioning unit has been frequent throughout the national territory due to the high temperatures throughout the year. With the increase in the number of conditioners installed in homes and connected to the electrical networks, the quality and consumption of energy changes, causing disturbances to the electrical power system. In order to reduce such problems and preserve the characteristics of the energy, more economical and efficient devices are chosen. However, it is important to take note of the different models of air conditioners available on the market, of the well-known inverter technology, and even the oldest models of the conventional type. Regardless of the type of air conditioner, everyone wants a model that consumes less energy. Therefore, there are other factors in these devices that often go unnoticed by the consumer. Factors such as imbalances, harmonic disturbances, among other existing variations, can cause several problems in the equipment and in the network, and in general reduce the quality of the energy. In this sense, it was proposed a comparative analysis of energy consumption and quality between two air conditioners, one conventional and the other of the inverter type, which were subjected to individual tests through an energy analyzer allowing, then, a real diagnosis of the behavior of each equipment, making it possible to evaluate the quality requirements to obtain the best performance of the equipment. The results obtained show the importance of the energy quality indexes, both for the consumer and for the concessionaires.
