AIRFLOW OPTIMIZATION FOR CABIN COMFORT

Disclosed examples relate to a Heating, Ventilation, and Air Conditioning (HVAC) apparatus for a vehicle. The apparatus includes a suction HVAC unit with a plenum, a hot air pocket extraction duct connected to the plenum, and one or more suction intakes connected to the hot air pocket extraction duct. The hot air pocket extraction duct is configured to draw hot air from a hot air pocket in the vehicle through the suction intakes into the plenum. The apparatus may include dashboard and/or roof suction intakes positioned in regions prone to hot air pocket formation. Methods for controlling climate in a vehicle cabin using the apparatus, manufacturing a vehicle with the apparatus, and optimizing the HVAC system are also described.
