PROBLEM TO BE SOLVED: To provide a roof snow-melting system being low in running cost.SOLUTION: A sealed space 2 using a sheet 4 is made under a snowfall surface for trying to melt snow, and a sealed space (a heating chamber) 5 having a heat source is provided under its space, and airtightness is held by directly connecting both spaces by a pipe. The snow is melted via the sheet by sending air warmed by the heating chamber to the sealed space by an air sending pipe based on the principle that warm air rises and cold air lowers, and the air chilled by snow-melting lowers in a recovery pipe, and returns to the heating chamber. The recovered air is reheated, and is circulated in the two spaces, so that the snow is melted by minimizing losing heat energy. Since there is risk of mixing condensation water and unexpected water leakage in the recovered air, the system is formed for separating water while holding the airtightness. |
