A dual-mode HVAC system for vehicles with reversible heat exchanger roles and an air rejection port for efficient climate control.

Patentradars sammanfattning

This invention discloses a vehicle HVAC system operable in at least two distinct modes, featuring two heat exchangers with switchable functional roles and an air rejection port positioned between them. In the first mode, the first heat exchanger cools while the second heats; in the second mode, their functions reverse. The air rejection port can expel a portion of circulated air to the external environment during either operating mode, enabling flexible thermal management and improved energy efficiency.
