A Survey for the Air Treatment System according to the Position of HVAC and the Feature of Air Duct Structure in the Train

철도 차량의 HVAC 위치에 따른 공기조화 시스템 및 Air Duct 구조의 특성에 관한 고찰

The HVAC and the air duct is to make optimal indoor environment. By the HVAC position, method and the air duct construction, the important elements can affect on cooling performance, passengers' convenience, and energy efficiency. According to this, there are features, such as the indoor temperature distribution, cooling performance, velocity distribution from diffuser, tend to be come out variously. Also, comparing and analysing temperature distribution, cooling performance, air velocity, noise based on the real practical vehicle tests, it shows features in detail. Besides, it can lead to make design the system of HVAC & air duct effectively.
