This paper presents a research project, of which the primary goal was to investigate the possibilities of designing a natural ventilation system with heat recovery solely driven by the indoor-outdoor temperature difference. The theory used for design of a prototype system and the prototype itself is describes as well as the measured performance. The project has shown that it is possible to design a natural ventilation system solely driven by the difference between the temperature indoors and outdoors with a heat recovery efficiency of 40-45%.
