Designing of a air-conditioning system using fuzzy logic with advantage of energy saving

Abstract

Air conditioners and air conditioning system are now an essential part of almost every building and institution. They consume a significant part of total energy consumption. Studies suggest that in locations like auditoriums, indoor stadiums and conference halls, air conditioning can contribute as much as 75% of total energy intake. Even in homes and offices, energy consumed by air conditioners is significant. As the user of AC is of elegant class so designing a controller to automate the AC must be compact with reducing the energy consumption by AC and the comfort factor. In this paper, a new scheme is provided which proposes a compact controller using fuzzy logic to maintain the temperature and the humidity close to the comfortable temperature. The proposed controller extremely reduces the use of remote control and human endeavor and maintains the reduction of the electrical energy consumption of the AC compressor/fan by controlling the switch and speed of the cooler fan while utilizing all available resources in the most efficient manner. In the proposed design, the energy consumption can be 40 percent lower than to the conventional one.
