Abstract:

Today air conditioning systems have been considered by all people as one of welfare requirements in buildings and closed environments. Conventional room air conditioners are controlled by thermostat with targeted temperature and no control over humidity. Fuzzy logic controller (FLC) was developed to maintain temperature and humidity at set conditions. Temperature and humidity are the inputs of the fuzzy logic control and outputs are the compressor and the Fan. ‘ColdAirIn’ and ‘HotAirIn’ represent ‘low and high’ heat of the Fan respectively. The paper presents the algorithm for intelligent air conditioning system. This algorithm is based on fuzzy logic. Fuzzy control is one of the methods which provide a powerful rule and methodology to guarantee Heating Ventilating and Air-Conditioning (HVAC). The designed system consists of two sensors for feedback control: one to monitor temperature and another one to monitor humidity.  The logic control was developed to control the operation mode of the air conditioning, and maintain the room set conditions. A fuzzy rule for this controller was formulated by temperature and humidity. The model of the controller was tested using MATLAB simulation. The system has proven to be a reasonable advancement in air conditioning system.
