초록
The internal environment in pig house is closely related to the animal productivity. In addition, it is important to consider a working environment insidethe pig house due to high gas and dust concentrations. The poor working environment inside the pig house can cause health problems includingrespiratory diseases. To analyze the working environment, it is important to evaluate the ventilation efficiency to effectively remove harmful gases anddust. The purpose of this study is to develop a 3D CFD model to analyze the working environment in the pig house. CFD model was validated bycomparing air temperature distributions between CFD computed and field measured data. The average air flow rate at the pig height was 40.1 % lowerthan the working height when incoming air was concentrated on upper layer by the installed ventilation system on the experimental pig house. Usingthe validated CFD model, the regional ventilation efficiency was computed by the TGD(tracer gas decay) method at the pig and working heights. Therewas a difference of ventilation efficiency on 14 % between the air stagnated section and the rest sections. Stagnated gas concentration can be effectedby animal and human health.
