摘要: Abstract In this study, energetic, exergetic, environmental and sustainability analyses their assessments are carried out for latent, thermochemical sensible thermal energy storage (TES) systems phase change material (PCM) supported building applications under varying environment (surrounding) temperatures. The present system consists of a floor heating system, System-I, System-II System-III. stays at the with unit pump. System-I includes latent TES fan. is comprised PCM envelope, in which from outside to inside; glass, transparent insulation material, PCM, air channel placed, respectively. Furthermore, mainly has solar-thermochemical while there an aquifer heat pump Among TESs, hot cold wells have maximum exergetic efficiency values 88.782% 69.607% 8 °C dead state temperature, According aspects discharging processes well possess minimum 5.782% 94.118% Also, fan used most environmentally-benign component among devices. sustainable found worst TES.
