Implication

Randomized trial reveals improved air quality and energy savings in vehicle cabins, suggesting effective ventilation solutions.

Key Points

  • This research aims to develop a ventilation system that improves air quality and reduces energy consumption in vehicle cabins.
  • Proposed an energy recovery ventilation system that uses heat exchange between cabin air and incoming fresh air.
  • Evaluated system performance using computational fluid dynamics simulations.
  • Measured carbon dioxide and suspended particle concentrations under different operational conditions.
  • Carbon dioxide concentration reduced from 7600 to 3000 ppm at low speed with 5 occupants in 30 min.
  • Suspended particles decreased to approximately 630 particles/cm3 at low speed and to 530 particles/cm3 at high speed.
  • Energy savings estimated at 79.6 W at low speed and 110.3 W at high speed.
