Today air conditioning systems have been considered by all people as one of welfarerequirements in buildings and closed environments. Since a considerable part of energy lossoccurs in ordinary modern systems, new strategies and solutions are developed in the field inorder to save amount of energy consumption and observe environmental considerations. Fuzzycontrol is one of these methods which provide a basic powerful rule for decisions made toguarantee optimal use of cooling and heating system. Hence in this research project datameasured by environment humidity and temperature were used as input variables and fan speedcontroller, humidifier, heaters, and compressors were used as output variables to regulate air flowrate and create humidity, cooling and heating conditions in the environment using fuzzy logic forsystem control.
