An Energy-Efficiency, Performance Study of, Vacuum Insulation Panels

Vacuum insulation panel (VIP) consists of the core materials that were encapsulated at low pressure in a very thin, low gas permeability and low conducting barrier. The paper presented herein focuses on a unique panel design based on the evacuated 100% open cell rigid polyurethane foam with getters encapsulated in laminated films under various conditions and the application of VIPs. A series of studies of the effect of the batch manufacture efficiency and the thermal conductivity performance of the VIPs was discussed. In this study, several pieces of VIPs were installed on the walls of a refrigerator, show-case and refrigerator vehicle cabinet to evaluate the energy efficiency by measuring the heat loss. Heat loss from a cabinet located in an environmental room was measured by a reversed heat leak method under testing conditions. The results show heat loss energy efficiency improving over 25% for mounting the VIPs on the refrigerator and the reverse heat leak is improved by 8.0% and 28.9% for the refrigerator vehicle cabinet and showcase, respectively
