Abstract

PURPOSE:To make indoor environment comfortable while decreasing power consumption by lowering room temperature when a radiant temperature rises and elevating the room temperature when the radiant temperature drops. CONSTITUTION:A radiant temperature detector 7 with a black surface so as to absorb the rays of radiant light is mounted into space to be controlled while the room temperature is controlled in response to the change of the resistance of the detector 7 so as to lower the target temperature of the room temperature in response to the intensity of the rays of radiant light. The controlling means consists of the first series connected circuit through the series connection of the detector 7 and a resistor 9 and the second series connected circuit of resistors 10, 12, and the second series connected circuit is connected in parallel with the first series connected circuit while a differential amplifier 14 is connected between the node of the detector 7 and the resistor 9 and the node of the resistors 10, 12. The input 8 of the differential amplifier 14 and room-temperature detecting signals 11 are compared and amplified, and output voltage 15 corresponding to indoor target temperature is generated.
