Abstract

PURPOSE:To regulate the temperature of an air conditioner automatically by converting variation in electric capacity due to the ascent and descent of the head of the mercuric column of a special mercury thermometer into an oscillation frequency and by detecting it by a balance detector for control over the air conditioner. CONSTITUTION:The mercury bulb part 2 of a special thermometer T and a semicircular metallic plate 3 sliding up and down in contact with a glass pipe 1 are connected to an oscillator 4. The metallic plate 3 is wide enough for the mercuric column head to move up and down, and its center line is aligned to the display scale of the thermometer to set a temperature, forming a capacitor by the metallic plate 3 and mercuric column. A frequency-voltage converter 6, a servomotor M, and a motor turning-angle detecting circuit 9 constitute a balance detecting circuit. As the mercuirc column head rises above a set temperature, the electric capacity increases to lower an oscillation frequency and the converter 6 generates a reverse voltage to reverse the motor M, thereby operating the temperature-regulating knob 7 of an air conditioner so that the temperature falls. As the mercuric column head falls below the set temperature, the reverse operation is performed so that the air conditioner holds the set temperature.
