A RESEARCH REPORT ON THE IMPROVEMENT OF AIR CIRCULATION INSIDE A RAILROAD CARRIAGE

SYANAI KANKI KAIZED NO KENYU NI TSUITE

The purpose of this research was to examine the air pollution inside a highly modernized railroad carriage using the new Tokaido line as an example. It was also aimed at finding a device to solve the problem. In the first test, the dust was measured using a dust meter, an air filter, a hygro-thermometer, and deodorant musk inside the controlled atmosphere carriage. In the second test, the air circulation in the carriage under operating conditions was studied. This carriage was equipped with a dust meter, an ionizer, an ion density meter, and an air filter unit with active carbon. The third test studied the influence of cigarette smoking in a carriage. Results show that the 35 cu m/min of fresh air provided by air circulation was sufficient in terms of 002 supply. Pollution increased while the train went through a tunnel. An ordinary ionizer could not cover a wide enough area in the carriage. Odor in the train was mainly caused by cigarette smoke, and a high-fidelity air filter was recommended to dimish the odor and dust density. Two problems left to further study are pressure in the high-fidelity air filter and economic feasibility of operation.
