Publication number: 20230259111Abstract: The purpose of the present invention is to provide an abnormality detection system and refrigerator, an abnormality detection method, and an abnormality detection program which can improve the accuracy of abnormality detection. The abnormality detection system comprises: an acquisition unit which acquires driving data of a refrigerator (11); a creation unit which creates a model capable of estimating a prescribed driving state of the refrigerator (11) on the basis of the driving data, when the driving data is non-trained data; a determination unit which compares an estimation value of the driving state, the estimation value being estimated by the model, with an actual measurement value corresponding to the driving state, and determines whether the driving data is an outlier; and an abnormality detection unit which performs, on the basis of the model, abnormality detection on the refrigerator (11), when the driving data is not determined to be the outlier.Type: ApplicationFiled: July 12, 2021Publication date: August 17, 2023Applicant: MITSUBISHI HEAVY INDUSTRIES THERMAL SYSTEMS, LTD.Inventors: Yuki NISHIZAKI, Satoshi NIKAIDO, Noriyuki MATSUKURA, Tatsuo ISHIGURO, Katsuaki MORITA, Ryuji IKEDA, Hirotaka OKA, Kenichi NAGAHARA
