Research on Utilizing Air Thermal Energy for Railway Facilities

To utilize air thermal energy for railway facilities, experiments were conducted on snow melting systems equipped with air thermal energy heat pumps at the Kanamaki and Gonen Snow Melting Bases on the Joetsu Shinkansen. In these experiments, system requirements for cold regions were clarified by adjusting the efficiency of defrosting operation, and the CO₂ reduction effect of interlinking heat pumps and boilers was confirmed.
