Air dehumidification unit and process

Abstract

An air dehumidification unit of a heating, ventilating, and air conditioning system includes an air flow channel configured to guide a flow of air through an evaporator disposed therein, and a drainage channel coupled to the air flow channel. The drainage channel has an internal volume configured to receive a fluid condensed at the evaporator from the flow of air. The air dehumidification unit further includes a heating device configured to heat the internal volume of the drainage channel from outside of the internal volume of the drainage channel to militate against a formation of ice therein. The invention also relates to a method for dehumidifying the air in the heating, ventilating, and air conditioning system of a motor vehicle using the air dehumidification unit.
