Abstract (en)

It was composed the formula for calculating the heat transfer coefficient of a building surface. This formula integrally evaluates the heating balance of the building, incondensable water vapour condition, constructional and technological rates. When the density of animals keeping is at the law rate (the density of total flow of animals to ground is 90 W/m2) rational outside building surface heat transfer coefficient is 5W/(m2.K). When the rate of the density is high (150 W/m2), then rational wall heat transfer coefficient - 3.6 W/(m2.K). It was composed the formula for calculating the cowshed ventilation system parameters, depending on outdoor air temperature. While the outdoor air temperature is dropping from +20 C to -20 C, the area of cowshed vent should be reduced 85%.
