ABSTRACT:
An improved micro-computer operated control device for an air conditioning system which is specially characterized in that the air volume produced by the air conditioning system can be automatically varied in correspondence to the temperature of a closed space is disclosed. A number of temperature sensing components are constantly monitored by a processing unit of the temperature data thereof which are compared with predefined temperatures provided by a function setting unit; the results of the comparisons are transformed into corresponding signals which are then transmitted to an output control unit; and a voltage regulator is actuated in accordance to the signals to adjust the voltage of the motor of a fan supplied by a power source so that the operation speed of the fan can be constantly varied in correspondence to the external temperatures, resulting in the air volume delivered by the fan varied accordingly. The constant variation of the air volume delivered by a fan and the on-off control of the heating or cooling source can thus enable an air conditioning system to smartly provide proper volume of hot air or cool air to a closed space according to the continual variation of the external temperature.
