A method and device for heat recovery are proposed, in which two circuit-connected heat exchangers (2, 3) are complemented by a refrigerating machine (6). The heat transfer medium of the heat exchangers (2, 3) is conducted directly through the cold and the warm side, that is to say through the evaporator (11) and the condenser (10), and more specifically in such a manner that the circuit (4) of the heat exchangers (2, 3) is not interrupted. In this manner, a considerable improvement of the heat recovery can be achieved. The method and the device are preferably usable in the heating of outside air for heating building rooms. <IMAGE> |
