초록 ▼

Disclosed is a method for operating an air conditioner which is basically composed of an outdoor unit and an indoor unit and whose operation is controlled on the basis of values measured by a plurality of temperature sensors. When any one of the plural sensors is disabled due to wire disconnection, short-circuit or like trouble, and when a specific sensor which has a complementary relation with the disabled sensor with respect to the heat cycle or which has an object of measurement substantially the same as that of the disabled sensor is normally functioning without any wire disconnection, short-circuit or like trouble, the value measured by the specific sensor is based to presume the value that will be measured by the disabled sensor if the disabled sensor functions normally, and the operation of the air conditioner is continued on the basis of the presumed value.

대표청구항 ▼

A method for operating an air conditioner to supply conditioned air to a room, comprising an outdoor unit and an indoor unit, said air conditioner being controlled by a plurality of temperature sensors including a suction air temperature sensor disposed in the indoor unit for measuring the temperature of suction air flow supplied to a heat exchanger in the indoor unit, and a radiation temperature sensor disposed in the indoor unit to measure the radiation temperature in the room, said suction air temperature sensor having a complementary relation with said radiation temperature sensor, said method comprising the steps of: detecting at least one of a wire disconnection and short circuit of said suction air temperature sensor; replacing a value measured by said suction air temperature sensor after the at least one of the wire disconnection and short circuit is detected with a value measured by said radiation temperature sensor if said radiation temperature sensor is operating normally; continuing the operation of said air conditioner by controlling the air conditioner with the value measured by said radiation temperature sensor.
