The frame walls were heated and allowed to cool in a dynamic wall simulator that replicated the sun's exposure in a wall on a typical summer day. Results showed that the paraffin-based PCM reduced the average peak heat flux by up to 9.2% and reduced the average total daily heat flow up to 1.2%. Powdered paraffin PCM reduced the average peak heat flux up to 9.3%, but did not decrease the total daily heat flow. Hydrated salt-based PCM and eutectic salt/paraffin PCM did not provide any thermal storage benefit. Equivalent thermal resistance for the paraffin-based PCM was 40% higher when compared to the control wall.111 pagesENThis item is protected by copyright and unless otherwise specified the copyright of this thesis/dissertation is held by the author.Mechanical engineeringPhase-change materialsPcmInsulationHeat transferThesisopenAccess
