A counterflow heat exchanger for gaseous media, especially an air heat exchanger, for the ventilation of air in buildings comprising a heat exchanger drum through which heat emitting and heat absorbing gaseous media flow alternately. Active surfaces of said drum are composed of a multilayered network in which at least one ventilator provides an incoming air flow and another provides an outgoing air flow. Heat exchanger drum substantially forms the fixed outer limit of the device and has the advantage of being driven by a turbulent regime air flow. |
