[The air conditioning system in locomotive compartments]

Development of the devices for the improvement of air chemical content of cabs, disposal of noxious aerosols and light aeroionic separation is one of the most urgent problems of optimization and sanitation of working conditions of locomotive engine-drivers. Sectoral laboratory of atmospheric air protection of the Ministry for Ways of Communication of the USSR developed a highly effective system of air purification and conditioning in locomotive's cabs. The system involved a draught agitator, devices of air electric heating, electrostatic air treatment, humidification and neutralization. The system ensured cabin's air recirculation 6 times per hour. Besides necessary air heating and humidification, air dustiness and microbic contamination decreased to 0.2 mg/m3 and about 100 colonies per m3, respectively. The level of air saturation by light aeroions increased from 500 to 1200 per cm3. At the system outlet there were no nitrogen and ozone oxides. The design of the system was covered by patent.
