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.
