PURPOSE:To provide a power demand controller for an air conditioner which can control power demand without impairing an optimum environment in a building by enhancing a stop priority at the conditioner having a large ratio of a change of a temperature difference of a set temperature to a room temperature. CONSTITUTION:References 10a, 10b denote operation controllers, which controls operations-stops of compressors 5a, 5b according to an operation signal and a stop signal of temperature difference comparators 12a, 12b for comparing room temperatures to be detected by temperature detectors 7a, 7b with set temperatures in a room set by temperature setters 9a, 9b. References 11a, 11b denote counters for starting counting by stop signals from the comparators 12a, 12b to count a time up to outputting of the operation signal. |
