Title:
SYSTEM AND METHOD FOR DETECTING ABNORMALITY IN AIR-CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/223557
Kind Code:
A1
Abstract:
This system (1) detects an abnormality in an air-conditioning system. The system (1) comprises a training device (100), an inference device (200), and an assessment device (300). The training device (100) trains an inference model (M1) using training data including air-conditioning-system operation data that is acquired within an operation period in which the air-conditioning system is operating normally from among successive first to Nth operation periods (where N is a natural number), the inference model (M1) inferring a normal value for a specific parameter of the air-conditioning system from the air-conditioning-system operation data. The inference device (200) infers a normal value from the air-conditioning-system operation data acquired in an (N+1)th operation period by using the inference model (M1). The assessment device (300) assesses, on the basis of a comparison of the normal value and the specific parameter in the (N+1)th operation period, whether or not there is an abnormality in the air-conditioning system in the (N+1)th operation period.
