A simple model is proposed to calculate the air temperature rise induced by a heat source in a compartment with displacement ventilation. The model is based on the mixing process in ventilation theory. Expressions for the hot air temperature are derived by considering the cases with and without a thermal plume region. Numerical studies in a chamber with displacement ventilation were performed with computational fluid dynamics to justify the predicted results.
