Unsteady Airway as an Effective Method of the Ice Melting Prevention on the Building’s Roof

Abstract

The presence of ice crusts and icicles on roofs is an urgent problem since they influence on the people safety and property which could be situated unde roof cornices. There are a lot of methods to stop icicle formation on the roofs. At present article is considered an efficiency of an unsteady airway. The unsteady airway can change its section area depending on the wind speed. Such a constriction allows entering into the attic a big volume of cold air. At that сontribution is find a speed of snow melting on the roof featured by the unsteady airway. Speed of the snow melting influence the speed of ice crusting. By estimating these factors can be made a conclusion that the unsteady airway helps to reduce a quantity of ice dams.
