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. 

Keywords
