Abstract

This study simulated snow melting and removal using hot waste heat air generated in a transmitter room which was used to melt and remove snow from a satellite antenna. The air was supplied at 30 °C and 20 m/s and removed the 10 mm thick snow cover within 17.6 min with the snowmelt consuming 135 W/m2 with an average melting rate of 0.57 mm/min. The heat dissipation from the waste heat air to melt snow could be on the order of 25.7–51.38 kW for wind speeds of 10–20 m/s. Thus, this waste heat snow melting system can reduce the power consumption by 32.0–50.8 kW compared with the conventional electric de-icing equipment which would reduce the power consumption by 68.1–91.0%, while also reducing the air conditioning power consumption by 2.9–5.8%.
