摘要:
A breathing mask has an air heat exchanger for transferring heat from air exhaled from a mask chamber to air drawn in to the mask chamber. The air heat exchanger comprises a first set of air flow channels in series with the filter for providing filtered outside air to the mask volume and a different second set of air flow channels for expelling air from the mask volume to the outside, and a thermal coupling between the first and second sets of air flow channels.
