PURPOSE:To make it possible to compute a fair service rate by measuring the temperature of air prevailing on the upstream side and the downstream side of a heat exchanger of a handing unit having a heat exchanger function and an air supply function and computing the heat consumption of the unit based on a maximum capacity and a rotary speed of an air supply fan. CONSTITUTION:A heating medium, which is water-fed to a feed line 2-1 of a circulation pipe 2, is water-fed to a heat exchanger 3 of a fan coil unit 4 (FCU) or an air handing unit 5 (AHU) installed to each of living rooms A and B and then, the heating medium is arranged to be returned to a heat reservoir 1. In such an air conditioning system as described above, a centralized control unit 13, which controls each of the units 4 and 5 and variable air capacity units (VAU) 11 to 11, computes the feed of a heating value from the AHU 5 on the basin of a differential air temperature between the upstream side and down stream side of the heat exchangers of the AHU 5 and a rotary speed of an air feed fan 8. The feed quantity of heat is divided on the basin of the consumption of air for each VAV, thereby computing the consumption of heat for each VAV.
