HVAC intake control based on condenser front temperature

摘要

Methods and systems for controlling a heating, ventilation, and air-conditioning (HVAC) intake. An air-conditioning control device receives the detected ambient air from an ambient air sensor, and the detected air temperature at a front of a condenser. The two temperatures are compared to determine whether to change the HVAC intake. In response to determining the air temperature at the front of the condenser is higher than the ambient air, the HVAC intake is placed into a recirculate position to allow air from the vehicle compartment to enter the HVAC intake.
