Summary

A numerical model, employing a local-averaging formulation, was developed for heat transfer and water vapour deposition within fiberglass insulation under air exfiltration and frosting conditions. In order to validate the numerical model, laboratory apparatus was constructed with a test cell. This allowed two-dimensional moist air exfiltration [0.5 to 1.5 L/(m2.s)] through a fiberglass insulation slab for a temperature range -20 to 21.5 deg C from the cold outside surface to the warm inside surface. Part 1 outlines the theoretical/numerical model and describes the experimental test facilities and the properties of the fiberglass insulation tested.
