System Components: Evaporator
The evaporator is located in the heater assembly and uses an encapsulated sensor to measure the temperature of the air coming off the evaporator. The evaporator is installed in the heater assembly after the blower and absorbs heat from the exterior or re-circulated inlet air. Low pressure, low temperature refrigerant changes from liquid to vapor in the evaporator, absorbing large quantities of heat as it changes state.
The evaporator (like the condenser) is a "heat exchanger." As air passes over the evaporator fins, the moisture condenses on the fins as the air cools. Water collects in the bottom part of the housing and exits the drain.
