Temperature control device for an atomic power facility

Purpose: To increase the energy-saving effect to a maximum in an atomic power facility by providing temperature detectors in both a blower position and respective temperature control chambers, and controlling the temperature on the basis of the lowest temperature signal among the positions. Constitution: Temperature detectors are provided in the vicinity of a blower, or in the blower, and respective temperature control chambers. The lowest temperature signal of the temperature signals from the blower and the respective control chambers is selected by a selector circuit, and an automatic control valve in a heating coil is controlled through an automatic regulator on the basis of the lowest temperature signal.
