시험선로 결빙방지를 위한 융설시스템에 관한 연구

초록

The snow melting system by electric heating wires which is adopted in this study is a part of road facilities to keep surface temperature of the road higher than freezing point of water for melting the snow accumulated on it. The system is designed to increase traffic safety and capacity.The electric heating wires are buried under paved road at a certain depth and operated automatically and manually. Design theory, amount of heating, and installation standard vary according to economic situation, weather condition, and installation place where the system applies. It is tried to figure out that the appropriate range of required heat capacity and installation depth and intervals for solving snowdrifts and freezing problems with the minimum electric power consumption. The most important factors to design the system are calculation of heating capacity depending on weather condition and depth and interval of the electric heating wires depending on air condition respectively. The study were performed under the range of the air temperatures(-2oC, -5oC, -8oC), the intervals of the electric heating wires(70mm, 100mm, 125mm), and the installation depths(50mm, 70mm, 100mm). The ready made commercial program package was used to verify the experimental results.기호 설명접수일 : 2005년 9월 14일조동현(책임저자) : 대진대학교 컴퓨터응용기계설계공학과E-mail : chodh@daejin.ac.kr Tel. 031-539-197한규일 : 부경대학교 기계공학부이안호 : 한국철도기술연구원 qs:영하의 눈이 0 oC 눈으로 되는데 필요한 비열 :융해열 :증발열 :대류와복사에의해전달되는열 s:강설강도 :대기 온도 [oC]:수막온도 [oC]V:풍속 [m/s]:수막에서의 증발열 : 증발압력
