EMU Air Conditioning
Cheng Ouyang Xia-mei Ma
Abstract
Taiwan is located in the subtropical zone with high temperature and humidity typical of an
island climate. This is aggravated by air pollution caused by traffic in the larger cities during
working hours. It is important to design a safe and comfortable riding environment to increase the
willingness of the public to choose to travel on the transit system and improve air quality while also
easing traffic congestion.
The basic design principle for the TRTS is to provide a safe, speedy, convenient and low
pollution-emitting riding space. The first considerations in the design cooperation between each
subsystem of the EMU are operation safety and ride quality. When thinking about the ride quality,
in addition to concerns about the construction of the propulsion and suspension system, the saloon
is designed to be airtight. On the one hand it lowers interior noise and aerodynamic impedance,
and on the other it allows the supply of air conditioning and prevents dust getting into the car. This
helps maintain good saloon air quality and raises the overall ride quality.
This text is a comprehensive introduction to the air conditioning system used in the EMUs of
medium/high capacity TRTS cars and describes our design principles for this subsystem and the
maintenance condition of units currently in operation. The latest international technology
development and related equipment with operating performance are also included in expectation of
continuous operation of the Rapid Transit System in the future.
Key Words：air conditioning, refrigerante, evaporator, ODP, conformable quality
