Honda Pilot: A/C System Description - Condenser

Sub Cool Cycle Condenser System

The condenser and receiver/dryer are integrated. The main A/C condenser changes the high pressure and high temperature refrigerant vapor from the A/C compressor into a high pressure and high temperature liquid. This allows the refrigerant to release heat to the outside air. The receiver/dryer acts as a reservoir of liquid refrigerant for the expansion valve. It also removes debris and moisture from the refrigerant. The sub A/C condenser cools the high pressure and high temperature liquid refrigerant even further to improve A/C performance.

A/C System Description - Evaporator Temperature Sensor

The evaporator temperature sensor is a stick-type thermistor located in the heater unit, with its sensing element in the airflow after the evaporator. The sensor is connected to the HVAC control unit or climate control unit and constantly monitors the evaporator temperature. The A/C compressor and fans are cycled off briefly if the temperature approaches the freezing point of water. If the evaporator temperature goes too low, the moisture condensing on its cold surfaces will freeze, causing restricted evaporator airflow and poor A/C performance.
