Thermal conductivity and latent heat thermal energy storage properties of LDPE/wax as a shape-stabilized composite phase change material

摘要: Abstract Phase change material (PCM) composites based on low-density polyethylene (LDPE) with paraffin waxes were investigated in this study. The prepared using a meltmixing method Brabender-Plastograph. LDPE as the supporting matrix kept molten compact shape during its phase transition from solid to liquid. Immiscibility of PCMs (waxes) and is necessary property for effective energy storage. Therefore, type can be used latent heat storage system without encapsulation. objective research use PCM composite integrated components passive solar wall. proposed TROMBE wall allows daily building envelope restitution evening, possible control air flux ventilated layer. An experimental set-up was built determine thermal response these solicitations. In addition, DSC analysis carried out. results have shown that most important properties at liquid states, like “apparent” conductivity, capacity fusion. Results indicate performance affected by effectiveness significant amount saving achieved.
