6 FAQs about [Capacitor indoor ventilation effect]
How does urban environment affect indoor ventilation?
This urban environment can hinder the natural flow of air, making it difficult for buildings to be adequately ventilated through natural means such as windows and openings. There are mainly three approaches to studying indoor ventilation: field measurements, experimental methods, and numerical simulations.
