What is the process of passive cooling in terms of air quality?

The process of passive cooling in terms of air quality primarily involves replacing heated air with fresh air. By allowing cooler outdoor air to enter a space, passive cooling methods help to dilute indoor air pollutants and lower indoor temperatures, leading to improved air quality. This natural ventilation can effectively remove accumulated heat and stale air, enhancing overall comfort and health.

While other aspects of passive cooling, such as reducing humidity and regulating indoor temperature, can contribute indirectly to air quality, the key mechanism is the exchange of indoor air with cleaner, fresher outdoor air. This exchange helps maintain a healthier living environment by ensuring that stale or contaminated indoor air is replaced with air that has a lower concentration of pollutants.
