New air-conditioned sleeper train compartments, the microclimate and air ion Survey

However, the low average wind speed and fresh air, air conditioning and ventilation system operation should ensure to meet the design standards. Electricity from the air ionization environmental point of view, the air inside the low concentration of negative ions, and with the longer running time decreased 10 hours after running the air already inside dirty level. 4.2 Discussion and recommendations directly to all new air-conditioned sleeper train using a variety of scientific and technological means to improve the ride comfort, cabin environment clean and tidy. However, from the comfort of human feeling for the angle of the air environment assessment,[link widoczny dla zalogowanych], the Air Quality Study 2005 12 4 253 * amount remains to be further improved. With the improvement of living standards and social exchanges become more frequent, bus travel has increasingly become a fashion of our people for recreation and travel the preferred way to office, people want to have a comfortable journey on the environment beneficial to humans. From our present investigation and test results, a new air-conditioned sleeper train can not fully meet this requirement,[link widoczny dla zalogowanych], the characterization of air quality inside as an important indicator of a status of an air ions is not ideal. For a limited staff-intensive closed space, such as vehicles,[link widoczny dla zalogowanych], ships and other modes of transport should be fully state their concern about air ions. Evaluation of ionic air using air as the environmental quality standard, the effect of years of investigation has been confirmed by research l5j. There is no respect in view of the national standards of air ions, suggest the department concerned in the health sector with the assistance of other measures, while in the air of negative ions from the perspective of improving the air quality inside.
