Abstract

An integrated thermal management system for a mobility is proposed. The integrated thermal management system is configured to secure the efficiency of various thermal management modes including heating, cooling, dehumidifying, and cooling of parts, and to be reduced in manufacturing cost and package size by reducing valves and pipes provided to implement the thermal management modes.
