| 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,... |

| A study was conducted to compare health status of male adult Wistar rats from two Experimental Animal Houses of UFMG with literature data of SPF (free from specific pathogens) and conventional rats. The animals were divided into two groups: Group I (n=10), rats from the experimental animal houses of FAFICH and Group II (n=10) from ICB and following aspects were studied: a) evident clinical signs (behavior modification, hair loss (alopecia), b) leukocyte counts, c) feces exam and d) histological study of the lungs. The rats did not show clinical signs. However, when compared with SPF and conventional rats, both the groups showed a significant increase (p<0,05) of leukocyte count. On feces exam we detected some parasites and on lung histological exam we... |
