Abstract

An air conditioning system comprises an outdoor unit and a plurality of indoor units, a plurality of delivery conduits for supplying working fluid from a variable capacity energy source located in the outdoor unit to the indoor units, and a plurality of control valves respectively provided in the delivery conduits. A temperature sensor and a reference temperature setting device are provided for each room for transmitting corresponding temperature data to a central control unit. The central control unit detects whether the sensed temperature of each room is increasing or decreasing as a function of time and whether the sensed temperature is above or below a predetermined temperature associated with a value established by the reference setting device. Based upon these data the central control unit provides a control signal for closing the valve to divert a certain amount of the total supply energy to other rooms. Another control signal is generated to increase the total amount of supply energy when the temperature level and its gradient of each room indicate a shortage of the total supply energy and to decrease the total amount when a total energy supply excess is indicated.
