Ventilated Double Window for the Preheating of the Ventilation Air Comparison of Its Performance in a Northern and a Southern European Climate

Abstract EN

Keeping the indoor air quality within the reference levels requires that the polluted indoor air be replaced by fresh air coming from the outside.

This paper presents a sensitivity analysis and a series of simulations where the performance of this passive system is studied.

The influence of each relevant factor, like the wind, the solar radiation, and the outdoor air temperature, is assessed.

Two different local sets of climatic data were chosen, a mild and a cold winter.
