PROBLEM TO BE SOLVED: To provide an air conditioning system that ensures ventilation requirement during cooling operation and attains both improved amenity and high efficiency thereafter.SOLUTION: An air conditioning system includes: an air conditioner provided with a refrigerating cycle for processing indoor sensible heat load; a ventilator that is controlled for air volume to ensure ventilation requirement according to indoor environment and that ventilates a room and processes indoor latent heat load; and a centralized controller for controlling the refrigerating cycle so that evaporation temperature becomes target evaporation temperature. The centralized controller determines a maximum value Te_max in a predetermined evaporation temperature range for attaining target indoor humidity on the basis of human-body latent heat load Qlm, outside-air latent heat load Qlo by ventilation of the ventilator, ventilation air volume VA of the ventilator, temperature and humidity Ta_o/RH_o of inflow air of a cooler, and temperature efficiency &eegr;t of a cooler for ventilator, and it determines the target evaporation temperature so that it increases within the predetermined evaporation temperature range as the sensible heat load (temperature difference &Dgr;T) decreases. |
