About the project
Theoretical and experimental evidence show that the consumption of a refrigerator can be greatly reduced by improving the thermal insulation of walls, such as using different blowing agents for polyurethane and the use of vacuum panels (VIPs).
In order to measure such gains, POLO has all the equipment and training required to perform reverse heat flow testing and mapping heat flow through the walls of refrigerator. For this assay, the laboratory has more than 50 heat flow sensors of the tangential type of high sensitivity and an infrared camera which permits a qualitative assessment of the distribution of heat flux. In addition, the laboratory has a thermal conductivity measuring precision capable of measuring values lower than 5 mW / mK.
