Abstract
An energy-saving heat exchanger for a VOC abatement system. The energy-saving heat exchanger includes a fresh air chamber for receiving fresh air from a blower; a heated air chamber for receiving heated air from a secondary heat exchanger of the VOC abatement system; a mixed air chamber provided at the outlet ends of the fresh air chamber and heated air chamber; and a heat exchange chamber leading from the heated air chamber and disposed in thermally-conductive contact with the fresh air chamber. An oxygen detector measures the oxygen composition of air flowing from the mixed air chamber and operates a damper which controls flow of air from the heated air chamber to the mixing chamber.
