Title:
AIR CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/175946
Kind Code:
A1
Abstract:
A first indoor device from among a plurality of indoor devices of this air conditioning system is provided with a first sensor for detecting a first state value that intended for controlling an air conditioning operation of the first indoor device. A second indoor device from among the plurality of indoor devices of the air conditioner, said second indoor device being other than the first indoor device, is provided with a second sensor for detecting a second state value that is intended for controlling an air conditioning operation of the second indoor device. The air conditioning system is provided with: a difference computation unit (41) that computes the difference between a detection value from the first sensor and a detection value from the normal second sensor when the first sensor is normal; and an estimation unit (42) that uses the detection value from the normal second sensor and the aforementioned difference to compute an estimated detection value of the first state value when the first sensor is abnormal. In the air conditioning system, an operation control unit for controlling operation of the first indoor device on the basis of the estimated detection value is provided to the first indoor device.
