ABSTRACT:
An air-conditioning apparatus capable of regulating temperature in a plurality of rooms independently of the other by adopting a variable air quantity control system, the apparatus being constructed with heat load measuring device for detecting a temperature condition in each room by a room thermostat and measuring the heat load in the room based on the condition signals derived from the detection of the temperature condition; damper control quantity determining device for determining the degree of opening of a damper in each branched duct on the basis of the measured result of the heat load; damper control device for controlling the degree of opening of the damper on the basis of the determination by the damper control quantity determining device; device for measuring the operating conditions of the air-conditioning apparatus with signals obtained from detection of pressure and temperature within the air duct after the damper control by the damper control device; device for determining the number of revolution of an air blowing fan with the pressure signal from the operating conditions measuring device and controlling the air blowing fan based on the thus determined value; and device for determining and controlling the capacity of a compressor based on the output signals signals from the heat load measuring device and the operating conditions measuring device.
