Abstract

The air purification system and method for purifying and cooling air for use in a building has an air pollutant removal stage, an air pre-cooling unit, and a dual cooling and water removal unit, including a cyclone separator having a cooling coil wrapped around the separator for condensing and removing water from the airflow. The method comprises the steps of removing pollutants from an incoming polluted airflow to provide a substantially pollutant free outgoing moist airflow; pre-cooling the substantially pollutant free moist airflow to provide a clean cool moist airflow; and condensing water out of the clean cool moist airflow to provide a substantially clean dry airflow suitable for use in a building.
