Use a pair of heat exchangers around the evaporator to improve dehumidification. One way to make it is to use two car radiators and a bilge pump or fountain pump. If you want dehumidification, turn the pump on. The first radiator will precool the air, allowing for a lower evaporator temperature for better dehumidification. The second radiator will then reheat the air while cooling the coolant for the first radiator.
My friend is not planning for that feature in her design, since the areas where hybrid A/C works the most efficiently are the areas that are naturally low in humidity.
