Efficient latent heat storage technology is getting significant interest from the researchers, scientist, and engineers who are involved in solar heating and cooling, waste heat utilization, and building energy management applications. The latter materials are employed most frequently in this connection owing to their pronounced energy storage capacity and moderate cost. The present work involves a numerical analysis for the assessment of heat transfer through paraffin wax RT42 when it is fully converted from solid to liquid phase in a spherical container with and without air layer. The interaction of the py-porosity combination was evaluated numerically with the use of ANSYS/FLUENT 16 program. As can be seen from the results, the increase in the complete melting time with the presence of the 1 mm thick air layer was 33.33% and that the presence of a 2mm air layer raised the complete melting time by 66. It was 66.67% higher than the control without the air layer. In this research, it is clear that air layers play a major role in the delay of the melting of paraffin wax.
