Abstract
The invention relates to a heat exchanger blockand to a heat recovery ventilation unitcomprising such a heat exchanger block. In the heat exchanger block, the individual flow cross-section (Q) of flow passages of said plurality of first air flow passages (AFP) in said parallel flow region (PF) and the individual flow cross-section (Q) of flow passages of said plurality of second air flow passages (AFP) in said parallel flow region (PF) gradually, preferably linearly, decrease along a straight line (x-x) perpendicular to the parallel air flow passages (AFPand AFP) and from said first wall (W) to said second wall (W) of the block.
