METHOD AND SYSTEM FOR REDUCING THE POSSIBILITY OF VEHICLE HEAT EXCHANGER FREEZING

Methods and systems for reducing the possibility of heat pump evaporator fin freezing are described. Evaporator fin temperature is compared to a threshold temperature that varies with vehicle operating conditions. Actions to mitigate evaporator fin freezing may be taken if evaporator fin temperature...

Zusammenfassung:	Methods and systems for reducing the possibility of heat pump evaporator fin freezing are described. Evaporator fin temperature is compared to a threshold temperature that varies with vehicle operating conditions. Actions to mitigate evaporator fin freezing may be taken if evaporator fin temperature is less than the threshold temperature.
