Heat recovery by cross flow

Original language description

Important problem of residential buildings, social centers etc. is the increased concentration of pollutants during use of the building / room. The air-tight outer housing is typical for new or reconstructed buildings, due to tight windows, outer thermal insulation, etc. It is good for the reduced heat consumption in winter period but there are some disadvantages, in general, too, known in general as the "sick building syndrome". For instance, the higher air humidity could result in water vapor condensation in the colder outer corners of the observed room and consequently in mould growth, or in assembling rooms (classrooms, etc.) with poor ventilation, the concentration of CO2 is increasing quickly over the hygienic limits and is the reason of fatigue, headache etc., or due to internal heat sources, the room temperature is increasing and it is necessary to keep it on a suitable level. Many other pollutants can be present in observed buildings, as for instance formaldehyde, radon, bacteria etc., but it is over the extent of this short paper. In standard rooms without ventilation or air conditioning, the natural or forced ventilation is used, only. Results of numerical simulations describe, how to simply remedy the so-called sick building syndrome and without any expenses to get and keep healthy living environment. The design of air conditioning units, taking into account all such pollutant sources, is well-known. Many producers offer many different units for various kind of use. In general, the costs are significant - not only investment, but operational, too. In reconstructed buildings is not space enough for such equipment. In each system of ventilation / air exchange is a part of polluted inner air replaced by fresh outer one. T
