Estimation of the specific enthalpy-temperature functions for plastering mortars containing hybrid mixes of phase change materials

摘要: The use of phase change materials (PCMs) for the building sector is increasingly attracting attention from researchers and practitioners. Several research studies forwarded possibility incorporating microencapsu- lated PCM in plastering mortars facades, pursuit increased energy efficiency associated with heat storage capacity PCM. However, most these are centred a single type PCM, which bound to be more adequate given season year (e.g. winter or summer) than all seasons. study proposed this work regards evaluation using one kind distinct melting ranges, here termed as hybrid PCMs, mortars, achieve adequately advantageous performance seasons year. To characterize specific enthalpy temperature should measured. main purpose was show conceptual feasibility combining PCMs evaluate behaviour resulting differential scanning calorimeter. results showed that mortar contains can predicted through superposition effects independent no interaction occurs between them. knowledge obtained experimental testing estab- lished bases framework numerical simulation real-scale applications, used ascertain concept decreases consumption heating/cooling demands buildings.
