Abstract

PURPOSE:To hold a comfortable air-conditioned state corresponding to a changing indoor environment by predicting a changing PMV value and controlling a plurality of air conditioners by the predicted value when the cleaning of the air such as ventilation is conducted in accordance with the quality of the air. CONSTITUTION:When an air conditioner 1 initiates an operation, detectors 7, 8, 9 and 10 detect an indoor temperature, an indoor humidity, a radiation temperature and an outdoor temperature, respectively, and a PMV value representing the degree of amenity is calculated from detection values. Then, the quality of the air is judged by a detector (for example, a gas sensor) 6 for detecting the pollution of the air and whether or not ventilation is conducted is determined. When the ventilation is not conducted at this time point, the operation of the air conditioners such as a heating and cooling equipment 1, a ventilator 2, a humidifier 3, a ceiling fan 4 and a floor heater 5 is determined and the air conditioners 1, 2, 3, 4 and 5 are controlled by the calculated PMV value. On the other hand, when the ventilation is conducted, the ventilator 2 is operated and the ventilation is conducted at the same time, whereby the changing PMV value is predicted, the operation of the air conditioning equipment 1, 3, 4 and 5 except the ventilator 2 is determined and the air conditioning equipments 1, 3, 4 and 5 are controlled by the predicted PMV value.
