Industry Issues ——
Industry Problem Analysis
01
Passenger Comfort & Air Quality
High passenger density in enclosed carriages leads to heat buildup, CO₂ accumulation, and rising humidity. Ensuring stable temperature, fresh air supply, and low noise is critical for passenger satisfaction.
02
Environmental & Climate Fluctuations
High-speed operation causes rapid changes in temperature, humidity, and pressure. Systems must adapt to extreme outdoor climates (−30°C to 40°C, humid or dry) while maintaining cabin stability.
03
Dust & Particulate Pollution
Tunnels and underground stations introduce high dust loads, which lower air quality and accelerate equipment wear. Effective filtration and purification systems are essential.
04
System Safety & Reliability
Any HVAC failure can compromise passenger comfort, disrupt train schedules, and even affect operational safety. High reliability and redundancy are mandatory.
05
Energy Efficiency & Cost Pressure
Rail HVAC runs continuously for long hours, often across diverse climates and passenger loads. Energy consumption is high, making efficiency and smart control vital to reducing operating costs.
