DESCRIBES the results of measurements of temperature and relative humidity in six different attics (roof spaces) under controlled conditions.All six attics have the same dimensions and have been constructed adjacent to each other in a single lme, but with different insulating materials and ventilated in different ways. Using this fund of measured data, a number of researchers have attempted to apply their mathematical models and, starting from the basis of measured ambient climatic conditions, have calculated expected values of temperature, relative humidity, and, in one case, the moisture ratio in the attics. The results of these calculations showed difficulties in matching the performance of the models to real conditions. Summarising the measurements and the calculations, we can note that:","PeriodicalId":435154,"journal":{"name":"Journal of Thermal Envelope and Building Science","volume":"263 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115675243","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}

During the aging of the pipes, the blowing agent, in this study CO2 for the PUR foam will diffuse out through the casing and air components will diffuse into the foam. This diffusion will deterio rate the thermal properties of the insulation foam. For district cooling pipes, in ward diffusion and condensation of water vapor may occur which may increase the risk for corrosion, change the thermal properties, and affect leakage alarms. Theo retical models for mass and heat transfer are developed and solved numerically. The importance of the quality of the casing, the insulation thickness, the wall thickness of the casing, and the surrounding temperature is studied. Results for the diffusion process, thermal conductivity, and amount of condensed water are presented. The quality of the casing has a vital importance on the diffusion process. With a higher density of the casing, the diffusion process will be slower and the deterioration of the thermal properties become slower. The surrounding temperature, the insula tion thickness, and wall thickness of the casing are also of great importance. The amount of condensed water in the PUR foam is found to be very small during a pe riod of thirty years and will hardly affect the thermal performance or the leakage alarms.","PeriodicalId":435154,"journal":{"name":"Journal of Thermal Envelope and Building Science","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128105668","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}

When it is desirable to in crease heat dissipation, this critical radius can be used in a definitive manner to maxi mize the heat dissipation. However, if it is desirable to decrease heat gain or heat loss, the critical radius only serves as a necessary condition, but it is not sufficient. To ad dress design of such thermal systems, a new crossover radius is introduced. A cross over radius is a radius greater than the critical radius and is defined such that the heat transfer with the corresponding amount of insulating material is equal to that of the bare thermal system. In order to make effective use of insulation (to prevent heat loss or heat gain) the outside radius of the insulated pipe must correspond to values greater than the crossover radius. In Part I cylindrical systems are considered while spherical systems are considered in Part II.","PeriodicalId":435154,"journal":{"name":"Journal of Thermal Envelope and Building Science","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114400123","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}
