Abstract
An environmental control system comprises room temperature measurement apparatus, a plurality of thermal sensors fixed on a mattress over abed, a plurality of humidity sensors fixed on the mattress over the bed, an air conditioning unit for varying the room temperature, and a control circuit. The control circuit determines a thermal sensation of a sleeper from measured values by a plurality of thermal sensors , determines a perspiratory sensation of the sleeper from the measured values by a plurality of humidity sensors, and controls the air conditioning unit so as to let the temperature of the air in the vicinity of the bed be different from the room temperature by an amount prescribed by the combination of the room temperature value and the thermal and perspiratory sensation values, thus maintaining a comfortable condition in the bedroom and on the mattress.
