ABSTRACT
The purpose of the research is to find adequate solution against rising damp in historical buildings. The improvement of this case is with ventilated air channel. Special part of historical buildings are churches because not use routinely as for example museums, galleries. We are designed 4 differently construction of ventilated air channel. These are: open or closed, with overpressure and underpressure. We use for verification relevance these construction we simulated in software Ansys CFX the air flow of channels. We modeling the equal segment of the channels. The best solution of these construction is the ventilated air channel with underpressure system. In this solution is the highest values of air velocity. Nevertheless this solution is not aesthetic form of construction because the pipes are set on the façade. But these pipes are put in the drainage pipe. This research should be offer for architects the solution against problems of rising damp for historical buildings. For find the right solution is necessary to research everyone case. The aim of the research is to prepare the design process of the ventilated air channels for the architects without simulation every building, cross section or geometry of these construction.
