Floor heating and displacement ventilation

A question raised about displacement ventilation, is whether floor heating can be utilised without disturbing the thermal stratification in the room. See Figure 1.Q?Figure 1 Too much floor heating may destroy displacement ventilationThis paper deals with the possibilities and limitations to floor heating with displacement ventilation. This paper shows that floor heating can be utilised with displacement ventilation for both industrial and non-industrial premises for normal airflow rates and normal floor heating rates.
