Thermal characteristics of a double roof / A.M. Baumgartner, Ronald L. Sack, J.J. Scheldorf.
Title: | Thermal characteristics of a double roof / A.M. Baumgartner, Ronald L. Sack, J.J. Scheldorf. |
Author(s): | Baumgartner, A. M. Sack, Ronald L. Scheldorf, J. J. |
Date: | 1989. |
In: | CRREL Special Report. (1989.), Vol. 89-6 (1989) |
Abstract: | Results of one-dimensionless, steady-state, heat-transfer model indicate that temperature increase between eave and ridge of cavity air in double roof is small, with implications for mitigating eave ice damming. Appropriate air cavity depths must be used for long roofs and various outside temperatures. Preliminary experimental results tend to substantiate analytical approach. Future refinements include improved analytical model and enhanced experiments to increase precision of temperature measurements and measure velocity profile in air cavity. |
