Parabolic antenna snow melting and removal using waste heat from the transmitter room

摘要

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 degrees C and 20 m/s and removed the 10 mm thick snow cover within 17.6 min with the snowmelt consuming 135 WI m(2) with an average melting rate of 0.57 min/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%.
