Abstract: A system for decreasing the response time of a vehicle heating ventilation and air conditioning (“HVAC”) system is described. A fan circulates air through a HVAC casing. Circulating air through the HVAC casing creates a high-pressure zone within the HVAC casing. A thermal expansion valve is located outside of the HVAC casing. An outlet port is located on the HVAC casing to allow air to be ported from the high-pressure zone toward the thermal expansion valve. Air ported from the high-pressure zone may be directed toward the thermal expansion valve by a nozzle. The air increases the temperature of the thermal expansion valve and allows additional refrigerant to flow through the thermal expansion valve.

Abstract: An HVAC duct system of a vehicle includes an air duct for providing a passageway for forced conditioned air. The air duct having a first imaginary axis extending substantially parallel with the passageway. An air duct register having plurality of vane-like members for directing the flow of air as it exits the register is coupled to the air duct. An opening of the air duct register defines an imaginary plane. The register has a second imaginary axis extending perpendicular to the imaginary plane of the register. An air flow straightener disposed within the air duct juxtaposed to the register and includes an air guide member. The air guide member receives the forced air flowing through the air duct in a direction substantially parallel with the first imaginary axis and redirects the forced air in a direction substantially parallel with the second imaginary axis for reducing noise as air passes the vanes.
