Selection of a phase change material by using the multi-criteria selection method for use in an automotive thermal insulation 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 have been carried out in the field of materials science that allow to control the interior environment of a car. This study proposes the use of alternative materials chosen through multi-criteria 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 multi-criteria analysis, taking into accounts that when using a thermal insulation based on a PCM, an electrical control system would not be needed. It was determined that the ideal PCM for this application is paraffin, given its melting point that is 37°C.
