The mathematical model employed is based on the Hottel-Whillier-Bliss formalism for solar collectors. The heat transfer ratio (γ) is found to be a very useful parameter in predicting the thermal performance of a heat pipe absorber. For solar heating applications, the heat removal factor (<em>F</em><sub>r</sub>) of the heat pipe system is apparently lower than that of an equivalent conventional system because of the extra heat transfer surface in the heat pipe system. This penalty, however, can be minimized by proper design at the heat pipe condenser and system manifold. In solar cooling applications, the heat pipe absorber manifests better heat transfer characteristics than the flow-through absorber because it attains very high values of γ.</p></div>","PeriodicalId":101171,"journal":{"name":"Solar & Wind Technology","volume":"7 4","pages":"Pages 349-354"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0741-983X(90)90020-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77459327","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}

This led to an improved method of calculating the transmission coefficients of insolation. This study extends the previous work to compute the daily global insolation received at Ibadan during the dust-free seasons (February-October) of the years 1975–1980.
