PURPOSE:To reduce the supply electric power by using a self-heating temperature measuring element of a thermistor and a diode, etc., in common as an electric heater, as well. CONSTITUTION:In the center part of a heat insulator 1, a containing part 2 which is penetrated to the surface and the reverse side is formed, brought to self-heating by electrifying, and also, a temperature measuring element 3 for measuring a temperature T of the containing part 2 is contained and provided. As for the element 3, a thermistor, a diode, etc. are used,power is supplied thereto, and also, a lead wire 4 for outputting a signal of the measured temperature T is connected. Subsequently, constant power is supplied to the element 3, the element 3 is brought to self-heating by a prescribed heating value, and in such a state, the temperature T of the element 3 is detected from an output voltage. Next, based on the temperature T, a temperature heat state of the indoor environment is detected in a shape of a feeling temperature under consideration of heat loss due to radiation and convection from the human body and wet heat radiation, and by this detecting signal, an air-conditioning machine is controlled. In such a way, since a self-heating temperature measuring element is used as an electric heater, as well, the supply electric energy can be reduced remarkably by a simple structure.
