The gas cooking device and the induction heating (IH) cooking heater is used for cooking. Weexamined a difference of diffusion characteristics of odor emitted at the gas cooking device and the IHcooking heater. The IH cooking heater has the advantage that it does not give out carbon dioxide (CO2)from burning during cooking. We evaluated deodorization efficiency of a new system which wasdeveloped to purify air pollution gas generated during cooking without using an exhaust air duct.
The indoor air quality management of the railroad passenger cabin is a hot environmental issue inmany countries. Especially, particulate matters are known to be harmful for lung and bronchus, andhigh concentration of carbon dioxide may cause headache and dizziness. Therefore, new regulation tolimit the particulate matters and carbon dioxide concentrations in the railroad passenger cabin is underpreparation in Korea. In this study, a new concept of an integrated novel air cleaning system for railroadpassenger cabin was suggested.
