Apparatus for studying transient heat and moisture transfer in fiberglass batt insulation.

Author(s) : COUVILLION R. J., HAWISA J. S., TATGE G. J.

Summary

The overall objective of the work was to measure transient moisture content and temperature distributions in a 15.2 to 30.4 centimeters thick slab of fiberglass batt insulation. The data were needed to verify a model of heat and mass transfer in fiberglass with diurnal varying temperature and humidity boundary conditions. The humidity-temperature control system uses a chiller to dry the air and steam or water to humidify to the desired level. Electric resistance heaters control the temperature. The system can produce sinusoidal or any chosen diurnal variation ranging from 5 to 50 deg C and 20 to 80% relative humidity. The system measures moisture content at eight points within the slab.
