YENİ TASARI ÜÇLÜ CAMLI FAZ DEĞİŞİM MADDELİ DUVARIN ENERJİ VE ÇEVRE DEĞERLENDİRMESİ

Research was conductedto investigate the performance of phase change material (PCM) walls for solarspace heating. The PCM walls were consisted of brick walls, plasterboardscontaining PCMs and novel triple glazing units. South façade of atest room was constructed using the PCM walls for heating the test room with solar thermal energy. The overall efficiency of the PCMwalls was experimentally determined on a monthly basis. Inaddition to experimental analysis, a theoretical energy analysis of the PCMwalls based on 10-year mean meteorological data was performed to provide a moregeneral conclusion about the performances of the PCM walls. Besides, reductionin CO2 from the test room owing to PCM wall was also calculated.Theoretical analysis results showed that, the reduction of CO2emission on a monthly basis varied from 57 to 7% during the heatingperiod. Heating period is from Octoberthrough May. Reduction of CO2 emission was 16% on an annual basis.
