HVAC FLAP

The heating, ventilation, air-conditioning and cooling (HVAC) system is designed to adjust, heat, cool, ventilate, clean, or dehumidify the indoor air quality (IAQ) in the car. The HVAC system consists of sensors and mechanical/electronic switches at the front end, blower motors, actuators (for fresh air circulation control, airflow control, and temperature control), and refrigeration units that deliver air to the cockpit at the rear end to ensure thermal comfort for drivers and passengers.

Based on MindMotion’s MM32SPIN023C microcontroller, the HVAC FLAP takes MM32SPIN023C as its main control.
