Thermal Performance of Animal Fat as a Phase Change Material for Space Heating in ‎Residential Buildings

Abstract

Phase change ‎materials (PCMs) are regarded as a possible solution for reducing the energy ‎consumption required for heating the ‎buildings by storing the heat daytime and releasing it at ‎night. Fatty acids are one of the organic phase change materials. It possesses some superior ‎properties over other PCMs such as low melting point, good chemical stability and non-‎toxicity thus it can be used as a suitable material for solar passive heating application. The ‎present study assists for the ‎utilization of PCMs in the roof of residential building to absorb ‎the heat comes from solar ‎radiation during the daytime and releasing it to the inside nightly. ‎Building considerations ‎as well as thermo-physical properties of PCMs have been taken and ‎measured experimentally. ‎Results have shown that these materials have a good potential for ‎reducing energy demand ‎and satisfy comfortable thermal conditions. The obtained readings, ‎from a rig model built for that purpose, ‎showed that the indoor temperature could increase by ‎‎3-6 oC in the winter compared to that ‎measured in a traditional one. Furthermore, a simulation ‎program depended on degree-days ‎method explained that the energy consumption could be ‎saved up to 55%. Thus PCMs could ‎submit encouraging suggestions toward the sustainability.‎
