Abstract

An air conditioning system includes a first chamber having a plurality of first sectors, a second chamber having a plurality of second sectors, a first airflow device forming a first airflow through the first chamber, a second airflow device forming a second airflow through the second chamber, and a heat and mass transfer substance flowing in a plurality of the first and second sectors, the substance interacting with the first and second airflows through the first and second chambers. Thermal inducement apparatus thermally interacts with the substance establishing a thermal gradient between the first sectors and a thermal gradient between the second sectors providing a heat and mass energy gradient for the first airflow through the first sectors and a reversed heat and mass energy gradient for the second airflow through the second sectors. Plumbing is provided, which moves the substance throughout the system.
