The transit system proposed for Hong Kong presents factors that make proper engineering of the environmental control system (ECS) critical. Hong Kong experiences severe temperature and humidity conditions many months of the year, and the urban railway is designed to carry almost twice the maximum passenger loading of other comparable systems. The objective of the environmental control system is to provide for the comfort and safety of people and protection of equipment. Generally stated, the ECS should maintain temperature and humidity within prescribed tolerances; achieve effective control of airflow (both velocity and direction), air-quality and air-pressure transients; protect against condensation; and operate acceptable noise levels in stations, tunnels and to the external environment. The several concepts investigated by the design team are described and evaluated.
