In recent years, great emphasis has been placed on ventilation and the losses that arise from it. We are starting to realize the need to provide comfort in space. While this is already progressing well with houses, vehicles or mobile homes in backlog. Since when using these vehicles we usually always have extremes of high and low temperatures, we ask ourselves what kind of ventilation would be the most expedient to choose. Is it natural, maybe forced, or is it worth trying recuperation.
In diploma thesis, we measure the air tightness of such a vehicle by measurements with a tracer gas and by measuring the increase of CO2 overnight in case that no form of ventilation was used. We also tested the efficiency of ventilation with a fan. This measurement was also performed with a tracer gas. In addition, we compared different methods for calculating air exchange.
Based on the measurements, we found that due to the small space in motorhomes, we need a large number of air exchanges for adequate ventilation. So it would be most expedient to choose ventilation with recuperation.
