Plate heat exchanger (6) is arranged so that a first part of each plate is in the intake air channel, and a second part of each plate is in the outlet air channel. Both the fresh air and the outgoing air flow through the intermediates spaces between the plates within the respective flow channel so that the heat of the air is transferred to one part of the plate, and conducted to the other part of the plate to be transferred to the air. At least one fan (11,12) is provided. |
