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 Air Conditioning (HVAC) systems for two main goals; energy recovery from the waste heat and /or dehumidification of the air. Performance of the heat wheel utilized merely for energy recovery has been numerically investigated in this study. For the aim of determining the optimum rotational speed, three different angular velocities have been used under the transient conditions. The findings obtained from the analysis have been compared to a validated experimental study in literature. Consequently, it has been observed that they are in good agreement each other.
