Abstract
An HVAC system that optimized for minimizing the amount of electrical power used during operation at various levels producing cold air or warm air is provided. The system includes an air inlet, a scroll, an air conditioning module, and an air delivery system for various locations within a vehicle that includes the HVAC system.
Claims18
An HVAC system for a vehicle, comprising:
- an air inlet housing that supports a fan housing, and a fan that is rotatably mounted within the fan housing, wherein air from the air inlet housing flows directly to a suction of the fan, and when the fan is rotating about its rotational axis air is expelled out of the fan substantially radially away from the rotational axis;
- a scroll that receives the expelled air from the fan when the fan rotates within the fan housing, wherein the scroll transitions from the fan housing to a pathway that leads to an air conditioning housing, the air conditioning housing includes an evaporator of a heat pump or refrigeration system associated with a vehicle, the scroll extends around the fan to direct air expelled from the fan to an exit of the scroll that transitions to an inlet into the pathway;
- wherein the pathway includes the inlet and transitions to an outlet that is proximate to an evaporator within an air conditioning housing, wherein a cross-sectional area of the pathway increases as the pathway extends from the inlet to the outlet.
