热交换器块和包括热交换器块的热量回收通风单元
Abstract:
本发明涉及一种热交换器块2并且涉及一种包括这种热交换器块的热量回收通风单元1。在所述热交换器块2中，所述平行流动区域(PF)中的所述多个第一空气流动通道(AFP1)的流动通道的单独流动截面(Q1)以及所述平行流动区域(PF)中的所述多个第二空气流动通道(AFP2)的流动通道的单独流动截面(Q2)沿着垂直于所述平行空气流动通道(AFP1和AFP2)的直线(x‑x)并且从所述块的所述第一壁(W1)到所述第二壁(W2)逐渐(优选地线性)减小。
Abstract(English):

The invention relates to a heat exchanger block 2 and to a heat recovery ventilation unit 1 comprising such a heat exchanger block. In the heat exchanger block 2, the individual flow cross-section (Q1) of flow passages of said plurality of first air flow passages (AFP1) in said parallel flow region (PF) and the individual flow cross-section (Q2) of flow passages of said plurality of second air flow passages (AFP2) in said parallel flow region (PF) gradually, preferably linearly, decrease along a straight line (x-perpendicular to the parallel air flow passages (AFP1 and AFP2) and from said first wall (W1) to said second wall (W2) of the block.
