Tyrime sulygintos senos kartos sniego valymo sistemos su nauja skaitmeninio valdymo šildymo sistema. Atsižvelgus į gautus rezultatus, pateiktiami pasiūlymai sniego valymo sistemoms efektyvumo didinimui. Tyrimas skirtas sistemų optimizavimui ir elektros energijos vartojimo mažinimui. / Point heating systems, used by SC „Lietuvos gelezinkeliai“, have to warrant safe and reliable train traffic. It is designed to melt ice which is between point’s spike and frame rail and accomplish heating elements’ and other system parts monitoring and control according the stated parameters. At present the snow blowing system use a lot of electrical energy, the research is dedicated to optimize the systems and to reeducated use of electrical energy.
