Abstract


Integrating energy (heat and moister) recovery ventilator and heat recovery ventilator has gained more attention recently as far as ventilation requirements and energy saving are concerned. In this paper, the selected ventilator employs rotary air-to-air energy wheel with a porous matrix under a medium of heat transfer. Such an energy wheel can operate with high effectiveness by using a low-cost porous matrix energy core. In order to determine the effectiveness of the energy wheel, a mathematical and numerical simulation model has been developed for a symmetrical and balanced wheel operating in a counter-flow arrangement. This sensible model is used for the examination of the effectiveness of the wheels during summer and winter. The effects of operating parameters such as rotational speed, gas velocity and volume flow rate on the performance of the process have been studied and compared with the available results of the literature
