Abstract
The present work focuses on modifying an existed commercial heat recovery ventilator unit. The heat exchanger (the core) of this unit is a fixed plate type operating in a crossflow arrangement without fins. The theoretical analysis is performed to investigate the effect of adding a suitable number of fins to the core in two conditions. These conditions are to investigate the effect of adding fins on the performance of the ventilation unit and the possibility of reducing the core size maintaining the original performance, provided that the added fins do not lead to exceeding the permissible pressure drop of 450 Pa at full capacity of 1000m3/h air flow rate. The obtained results indicate that adding fins up to 144 fins per meter makes the heat recovery ventilator has its highest performance with an increase in effectiveness by 33.3%. The lowest volume that can be obtained without compromising the performance of the exchanger is 37% of the original volume by adding 120 fins/m.
