| Abstract | This paper deals with the problem of estimating surface heat losses from heated pavements used to melt snow. The study is based on an extensive review of the literature and on tests carried out over three winter periods on an embedded snow melting system located on the grounds of the National Research Council, Ottawa. Formulae for estimating surface heat loss are compared with those recommended in the ASHRAE Guide and Data Book, the only comprehensive guidelines available in North America for calculating the design heat requirements of embedded snow melting systems. Several case histories of snow melting tests are presented to illustrate the problems of estimating surface heat loss during and immediately following snowstorms. It was found that the ASHRAE formulae gave reasonable results, provided adjustments were made for the height at which wind speeds are measured. The limiting condition controlling design surface heat loss for snow melting systems operating in cold climates is the maintenance of an ice-free surface immediately following snowstorms rather than the effective melting of snow during a storm. |
