To predict the amount of refrigerant in refrigerators with the best performance, this study used refrigerator data collected in real time via the Internet of Things, which were screened to include only the effective parameters related to the compressor and refrigeration properties (based on their practical significance and the research background) and cleaned by applying longitudinal dimensionality reduction and transverse dimensionality reduction. Then, on the basis of an idealized model for refrigerator data, a model of the relationships between refrigerant amount (the dependent variable) and temperature variation, refrigerator compartment temperature, freezer temperature, and other relevant parameters (independent variables) was established. A refrigeration model based on a neural network was then established for predicting the amount of refrigerant and was used to predict five unknown amounts of refrigerant from data sets. BP neural network and RBF neural network models were used to compare the prediction results and analyze the loss functions. From the results, it was concluded that the unknown amount of refrigerant was most likely to be 32.5\u2009g. It is of great practical significance for refrigerator production and maintenance to study the prediction of the amount of refrigerant remaining in a refrigerator.<\/jats:p>","DOI":"10.1155\/2020\/1743973","type":"journal-article","created":{"date-parts":[[2020,2,3]],"date-time":"2020-02-03T18:30:25Z","timestamp":1580754625000},"page":"1-12","source":"Crossref","is-referenced-by-count":3,"title":["Intelligent Prediction of Refrigerant Amounts Based on Internet of Things"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5605-2032","authenticated-orcid":true,"given":"Jincai","family":"Chang","sequence":"first","affiliation":[{"name":"College of Sciences, North China University of Science and Technology, Tangshan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiuling","family":"Pan","sequence":"additional","affiliation":[{"name":"College of Sciences, North China University of Science and Technology, Tangshan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhihao","family":"Shen","sequence":"additional","affiliation":[{"name":"College of Sciences, North China University of Science and Technology, Tangshan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hao","family":"Qin","sequence":"additional","affiliation":[{"name":"College of Sciences, North China University of Science and Technology, Tangshan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"doi-asserted-by":"publisher","key":"1","DOI":"10.1002\/cpe.3165"},{"issue":"4","key":"2","first-page":"52","volume":"53","year":"2017","journal-title":"Fujitsu Scientific & Technical Journal"},{"doi-asserted-by":"publisher","key":"3","DOI":"10.1109\/comst.2015.2444095"},{"doi-asserted-by":"publisher","key":"4","DOI":"10.1016\/j.comnet.2014.11.008"},{"doi-asserted-by":"publisher","key":"5","DOI":"10.1016\/j.future.2015.09.021"},{"doi-asserted-by":"publisher","key":"6","DOI":"10.1109\/jiot.2017.2683200"},{"doi-asserted-by":"publisher","key":"8","DOI":"10.1016\/j.cirp.2016.04.062"},{"doi-asserted-by":"publisher","key":"9","DOI":"10.1016\/j.apenergy.2014.09.011"},{"issue":"1","key":"10","first-page":"7","volume":"12","year":"2018","journal-title":"International Journal of Design"},{"doi-asserted-by":"publisher","key":"11","DOI":"10.1109\/JSEN.2016.2565621"},{"doi-asserted-by":"publisher","key":"12","DOI":"10.1016\/j.ijrefrig.2018.11.012"},{"doi-asserted-by":"publisher","key":"13","DOI":"10.1016\/j.ijrefrig.2014.12.023"},{"doi-asserted-by":"publisher","key":"14","DOI":"10.1016\/j.ijrefrig.2018.09.020"},{"doi-asserted-by":"publisher","key":"15","DOI":"10.1007\/s00231-017-2173-6"},{"doi-asserted-by":"publisher","key":"16","DOI":"10.1016\/j.ijrefrig.2015.08.015"},{"doi-asserted-by":"publisher","key":"17","DOI":"10.1016\/j.ijrefrig.2017.05.032"},{"doi-asserted-by":"publisher","key":"18","DOI":"10.1016\/j.ijrefrig.2005.11.008"},{"doi-asserted-by":"publisher","key":"19","DOI":"10.1007\/s40997-017-0110-4"},{"year":"1991","key":"20"}],"container-title":["Complexity"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/complexity\/2020\/1743973.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/complexity\/2020\/1743973.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/complexity\/2020\/1743973.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,2,3]],"date-time":"2020-02-03T18:30:35Z","timestamp":1580754635000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/complexity\/2020\/1743973\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,2,3]]},"references-count":19,"alternative-id":["1743973","1743973"],"URL":"https:\/\/doi.org\/10.1155\/2020\/1743973","relation":{},"ISSN":["1076-2787","1099-0526"],"issn-type":[{"type":"print","value":"1076-2787"},{"type":"electronic","value":"1099-0526"}],"subject":[],"published":{"date-parts":[[2020,2,3]]}}}
