AIR-CONDITIONING DEVICE
First Claim
Patent Images
1. An air-conditioning device conditioning air in an indoor space, the device comprising:
- an indoor unit drawing indoor air, adjusting a temperature of the indoor air drawn, and expelling the indoor air into the indoor space;
a suction air temperature sensor provided in the indoor unit to measure the temperature of the indoor air drawn into the indoor unit;
a wireless temperature sensor unit separate from the indoor unit and separate from a remote control unit for the air-conditioning device, the wireless temperature sensor unit including an ambient temperature sensor and a transmitter, the ambient temperature sensor measuring an ambient temperature, the transmitter transmitting a signal of a measurement value (Tm2) of the ambient temperature sensor by radio;
a receiver receiving the signal transmitted by the transmitter, the receiver configured to determine whether or not the wireless temperature sensor unit is in an abnormal condition, based on a fact that a predetermined abnormal operation condition is satisfied; and
a controller configured to control an operation of the air-conditioning device based on a measurement value (Tm1) of the suction air temperature sensor if it is determined that the wireless temperature sensor unit is in an abnormal condition.

Abstract
An air-conditioning device includes: a suction air temperature sensor provided in an indoor unit; a wireless temperature sensor unit separate from the indoor unit; an abnormal condition determining section determining whether or not the wireless temperature sensor unit is in an abnormal condition; an index setting section setting a temperature index value; and a controller controlling operation of the air-conditioning device based on the set temperature index value. While the abnormal condition determining section determines that the wireless temperature sensor unit is in the abnormal condition, the index setting section determines a measurement value of the suction air temperature sensor to be the temperature index value.
