ABSTRACT:
A vehicle heating, ventilation and air conditioning (“HVAC”) system includes an HVAC control, a fan, an evaporator downstream from the fan, a cooler box downstream from the evaporator, a condenser in fluid communication with the evaporator and a compressor in fluid communication with the condenser and the evaporator. A method for cooling items using the HVAC system includes detecting a cooler box signal from the HVAC control, in response to detecting the cooler box signal, opening or closing a valve interposed between the evaporator and the cooler box, and in response to detecting the cooler box signal, performing at least one of the following: changing an HVAC mode or adjusting power delivered to the fan. Opening the valve can allow cool air to travel through a passage toward the cooler box. Closing the valve can block cool air from traveling through the passage toward the cooler box.
