Determination of Optimum Rotational Speed of the Heat Wheel through Computational Fluid Dynamics Simulation

Abstract

Heat wheel is a kind of regenerative heat exchanger mostly used in Heating, Ventilation and AirConditioning (HVAC) systems for two main goals; energy recovery from the waste heat and /ordehumidification of the air. Performance of the heat wheel utilized merely for energy recoveryhas been numerically investigated in this study. For the aim of determining the optimum rotationalspeed, three different angular velocities have been used under the transient conditions. Thefindings obtained from the analysis have been compared to a validated experimental study inliterature. Consequently, it has been observed that they are in good agreement each other.
