  • Electric vehicle HVAC system which cools battery and controls grille shutter based on coolant pressure
    Patent number: 11865898
    Abstract: Coolant flowing from a compressor passes through a heat exchanger and opening-degree adjustable type of expansion valves for heating, and an external heat exchanger. The coolant passing through the external heat exchanger is capable of passing through an expansion valve and a heat exchanger for cooling, and an expansion valve and a heat exchanger for cooling a battery. A grille shutter to change an introduction state of traveling air is provided in front of the external heat exchanger. When pressure of the coolant (particularly, pressure of the coolant at a timing after the coolant passes through the external heat exchanger) is a specified pressure or lower, the grille shutter is closed, whereby the heat-exchange performance of the external heat exchanger is lowered.
