There are a total of 696 hospitals in South Africa (SA) with a total thermal energy demand for 20 hot water of 370 GWh per year. A total installed collector area of 73 972 m2 to 147 944 m2 across all hospitals in SA would increase the overall ST capacity of all these hospitals to compensate for 20 to 40% of their combined annual thermal energy demand. The major limiting factor for the uptake of ST technologies in South African hospitals is the current wide spread use of coal fired boilers as well as heat-pumps, making the adoption of ST technologies less feasible from a financial perspective. 25","PeriodicalId":424759,"journal":{"name":"Conference proceedings ISEC 2018","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116921902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use-case consists of 36 process streams which can be considered large-scale. Stream data is available for a period of three weeks with high temporal resolution. Even though a slightly different data basis is needed, both approaches yield comparable results which are analyzed in this paper. The first approach considered in this work is the software tool SOCO which is based on pinch-analysis for time-dependent process streams. It incorporates a flowsheet simulation environment for detailed storage simulation. The second approach is based on mathematical programming and cost-driven superstructure optimization using simple storage models. The best results obtained using both approaches are compared regarding heat exchanger networks, storage integration and economic data. Also, potential synergies between the two approaches are identified that could further improve solutions.","PeriodicalId":424759,"journal":{"name":"Conference proceedings ISEC 2018","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126654212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
