Simulation versus experimental results of VIPs embedded within PU insulation.

Number: pap. S2-P2

Author(s) : HAMMOND E., MICIC G.

Summary

Published attempts to use VIPs (vacuum insulation panels) to improve the thermal performance of cool boxes had found that VIPs do not yield their expected benefits, often only realising 2.5 to 3 times the improvement over PU (polyurethane) rather than the expected 5 fold benefit. This paper investigates an alternative method of employing VIP technology, embedding VIPs into a PU foamed cavity. The overall thermal conductivity value was calculated for the insulation of a fully foamed cabinet, with and without VIPs inset, using SolidWorks software. The measured thermal performance, from the warm-up time of the cabinet with a known thermal mass inside, was then compared to the calculated improvement expected. The model predictions used manufacturers’ data for the thermal properties of the insulation and showed good agreement with the measured performance. This suggests that the expected benefit of a VIP can be realised when the VIP is inset into a PU foamed wall.
