In the present study, glycine was chosen as temperature regulator to tune phase change temperature of NaAc∙3H2O with the objective of obtaining a non-eutectic SAT-glycine mixture with the targeted phase change temperature. In order to confirm the optimal glycine mass fraction in the mixture, DSC scan was conducted to measure the phase change properties of SAT-glycine mixtures with different glycine mass fractions. The corresponding DSC curves and the associated thermal parameters including

Floor radiant heating embedded phase change materials (PCMs) are a prospective field owing to its highly efficient energy-saving effect and comfortable thermal environment. In this work, using a non-eutectic mixture comprised of NaAc center dot 3H(2)O (main PCM) and glycine (temperature regulator) as PCM, and expanded graphite (EG) as supporting material, a novel composite PCM with high thermal performance used in the heat exchanger for the floor radiant heating was developed. The composition of the composite PCM was optimized, and its properties were studied. The results showed that the mixtu...
