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: Autonomic cooling of a substrate is achieved using a porous thermal protective layer to provide evaporative cooling combined with capillary pumping. The porous thermal protective layer is manufactured onto the substrate. A vascular network is integrated between the substrate and the protective layer. Applied heat causes fluid contained in the protective layer to evaporate, removing heat. The fluid lost to evaporation is replaced by capillary pressure, pulling fluid from a fluid-containing reservoir through the vascular network. Cooling occurs as liquid evaporates from the protective layer.

When the abnormality is determined to be the restorable abnormality, it is determined whether or not the restorable abnormality has been removed. Heating by the heater is prohibited when the restorable abnormality or the non-restorable abnormality has occurred. Heating by the heater is restored when the restorable abnormality has been removed after heating by the heater is prohibited due to occurrence of the restorable abnormality.
