Resumo: 	This paper is focused on the Computational fluid dynamics (CFD) modeling of regenerative heat exchanger suitable for animal houses. Buildings used for housing of animals in farms with intensive breeding, like poultry or pig houses, are characterized by high generation of heat inside, partly produced by animals, and in the case of small young animals, supplemented also by heating. On the other side these buildings need intensive ventilation which causes big losses of energy by exhausted air. A good way how to reduce heat losses can be the use of technical systems of heat recovery. There are two principal constructions of heat exchangers for heat recovery. There are either recuperative or regenerative heat exchangers. Industrially produced heat exchangers, commonly used in residential or industrial buildings, can be used in agricultural conditions only with difficulties, mainly because of the high dust concentration, which is extremely high in animal houses.  The methods of CFD modeling were used to calculate main parameters of special heat exchanger, developed for application in animal houses. The construction of regenerative heat exchanger with fixed matrix is based on heat accumulation in material of matrix in the form of massive plates. The program Fluent was used for airflow and heat exchange simulations. Results of simulations were verified by measurement of prototype of real heat exchanger.
