| 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,... |

| Milking is a key operation on dairy farms. The capacity and function of milking parlor influences production conditions (time of operations, needs of labor, total costs), so actually it affects the efficiency of the whole dairy farm. This paper presents a structure and principal parts of mathematical model which was created with the aim to enable to farmers and designers to choose suitable type of milking parlor for specific farm conditions. Three principal questions important for optimization of milking parlor are: technical parameters, indicators of labor productivity and economic criteria. The model structure was created with the aim to find the answer to all of them. The model includes in calculation main parameters of typical arrangements of milking... |
