Respirator with a circuit for breathing gas

摘要

A gas mask and breathing equipment is provided with a circuit for breathing gas and with a heat exchanger (7) cooled by an evaporating agent. The evaporating agent is introduced from an evaporating agent container (8) into the heat exchanger (7) via at least one group of spraying elements (9) and a gas delivery means (11) allows a gas volume flow to flow through the heat exchanger (7).

主权项

1. A gas mask and breathing equipment comprising:
a circuit for breathing gas; a heat exchanger connected to said circuit, said heat exchanger being cooled by an evaporating agent and said heat exchanger including a first duct for the breathing gas and a second duct, said first duct of said heat exchanger being thermally and mechanically coupled with the second duct of the heat exchanger via a heat exchange surface; an evaporating agent container with evaporating agent; a spraying element configured to directly apply said evaporating agent across a surface defining at least a portion of said second duct; a gas delivery means to send a gas volume flow through said second duct of said heat exchanger, said first duct being located on an incoming flow side of a user of the gas mask and breathing equipment.
