Design and implementation of an intelligent controller for a split air conditioner with energy saving

摘要

Air conditioners are designed to provide comfort and traditionally controlled using thermostat with targeted temperature and without considering effect of relative humidity. This paper details about a model developed using Fuzzy Logic Controller (FLC) and tested for comfort environment based on ET* (Effective Temperature). Temperature and relative humidity of room to be air conditioned are the inputs of FLC to control the compressor ON-OFF. Consequently air conditioner maintains both temperature and relative humidity near ET* and the compressor will stay off for significant period to save energy.
