Heating, ventilation and/or air-conditioning system for use in vehicle, has air circulating channel and air circulating lattice provided in front of fan, where lattice comprises carrier on which water-absorbing material is applied

摘要

The system has an air circulating channel (2) and an air circulating lattice (1) provided in front of a fan (4), where the lattice comprises a carrier on which a water-absorbing material (8) is applied by coating or encapsulation. The water-absorbing material is formed by an organic or inorganic Sorbentium e.g. zeolite and silica gel. The carrier is made of metal and/or plastic. The lattice is integrated with sorbents, which adsorb pollutants and odor and act as a filter (5). Desired aerodynamics and acoustics of the channel are achieved by appropriate design and layout of the lattice.
