EFFECT OF ADDITIONAL INSULATION PANEL ON AVERAGE TEMPERATURE IN SUBWAY CABIN DURING HEATING

초록

Thermal insulation performance of rail car is getting more important to save more heating and cooling energy. Since the body of the rail car is mostly made of metals (e.g., steel, aluminium, etc.), most of rail cars without insulation panels tend to have poor thermal insulation performances. There are several ways to enhance the thermal insulation performances of the rail car, but their effects had not been numerically measured based on the experimental results. In this study, a large climatic chamber, which can accommodate a cabin, was used to investigate the effects of various factors (e.g., blockage of doors/windows, power of heaters, additional insulating panels, door pocket blocker, etc.) on the thermal insulation performances of subway car.
