Phase change material selection by using the multi-criteria selection method for use in an automotive thermal storage system

Abstract:

The temperature that a car can reach inside is between 25 °C to 40 °C in certain environmental circumstances, for this reason, studies has been carried out in the field of materials science that allows to control the interior environment of a car. This study proposes the use of phase change materials chosen through multicriteria selection in order to apply them in thermal insulation, to control the interior temperature of the vehicle when it is parked. Starting from a list of candidate materials, the best material that meets the objective of constantly controlling the interior temperature of a car is determined by multicriteria analysis, taking into account that when using a thermal insulation based on a phase change material, heat electric control systems that raises the cost of a car are no longer needed. It was determined that the ideal phase change materials for this application is paraffin, given its melting point that is 37 °C.
