This paper presents influence of direction and energy of wind on forming of ventilation air velocity in chosen area of the free stall barn during summer. Based on analysis of obtained measurement results characteristics of the wind speed in summer was made. Variability of the ventilation air velocity with take into account of perpendicular and parallel wind direction was determined. Noticed differentiation of air velocity depending on measurement place - central barn area was less ventilated than area close to wall. Proposals setting out the reasons for the abnormal air flow were formulated. In order to increased ventilation air velocity in central part of the barn recommended use to air mixers. Attention was drawn to need of continue studies of different barn types relative to building construction solution and its localization.     ...

Analysis of effectiveness of the stables natural ventilation in the winter period

The aim of this study was analyze of the efficiency of the natural ventilation in the horse stable and an indication of opportunities to improve its operation. The study was conducted in Glinik Zaborowski in the winter. The scope of the research included measurements of air velocity with opened and closed windows and gates. Based on the results of the measurements and observations, it was found that the efficiency of the ventilation was very low. Average values of the air flow ranged from 0.06 m•s-1 to 0.12 m•s-1. These values were lower than the minimum air velocity recommended. The main reasons for very low air velocity in the horse stable was incorrect location and the wrong design solutions, among which the most important were: the lack of ventilation aparatures and abnormal direction of opening windows ...
