Abstract

A thermal load management system for a water management system includes first and second heat exchangers through which a liquid desiccant flows. A refrigerant utilized in a refrigeration cycle also flows through the heat exchangers. A first airflow flowing into a collection chamber of the water management system passes through the first heat exchanger, and heat is transferred from the first airflow and the desiccant to the refrigerant. A second airflow flowing into a regeneration chamber of the water management system passes through the second heat exchanger, and heat is transferred to the desiccant and the second airflow from the hot refrigerant. As the thermal loads of the refrigerant, the desiccant, and the airflows change, the thermal load management system can adjust the amount of heat transferred without external controls.
