Air-conditioning device
First Claim
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, 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 of the ambient temperature sensor by radio;
a receiver configured toreceive the signal transmitted by the transmitter;
determine whether or not the wireless temperature sensor unit is in an abnormal condition based on whether one or more predefined abnormal operation conditions have been satisfied, one of the abnormal operation conditions to be satisfied being a measurement value of the suction air temperature sensor being less than or equal to a predetermined first temperature threshold or greater than or equal to a predetermined second temperature threshold, the second temperature threshold being greater than the first temperature threshold;
set a temperature index value serving as an index of indoor temperature such that when the wireless temperature sensor unit is determined to be in an abnormal condition the temperature index value is set to the measurement value of the suction air temperature sensor and otherwise the temperature index value is set to the measurement value of the ambient temperature sensor; and
a controller configured to control operation of the air-conditioning device based on the temperature index value set by the receiver.

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.
