Abstract
A method of operating a heating, ventilation and air conditioning (HVAC) system of a vehicle includes operating the HVAC system in a heating mode to heat a supply airflow and direct the heated supply airflow into a passenger compartment of the vehicle; and selectably directing a flow of refrigerant through an evaporator of the HVAC system to reduce a relative humidity of the supply airflow by condensing excess moisture out of the supply airflow at the evaporator.
