Resumo

The aim of this work is to determine the environmental conditions to which animals are subjected in the weaning phase in conventional pig farm, analyzing the performance of air conditioning installations. The study was conducted in a pig farm located in the northwest. Measuring instruments were installed in a weaning room of piglets from 6 kg to 20 kg live weight. These instruments collect data of environmental comfort factors and energy ones related to the performance of air conditioning facilities: air temperature, relative humidity and CO2 concentration. In addition, performance data of air-conditioning and outside environmental conditions were recorded. Data recording was made between 06/10/2011 and 21/05/2012, encompassing five complete cycles of weaning. The main environmental control problems were: (1) Sharp fluctuations of room temperature, reaching much higher values than recommended, (2) high values of indoor humidity and CO2 concentration, mainly during the early stages of the cycle, (3) mismatch between heating and ventilation installations which brings excessive energy consumption. R2 correlations above 0,80 were also observed between the outside temperature and power demands in the interior ventilation of the room.
