Abstract
The measurement of ventilation rate is necessary for good climatic control in pig houses with natural ventilation and heating. A model based on a carbon dioxide balance is developed for pig houses. Included are diurnal variation patterns in carbon dioxide production. The model can estimate the ventilation rate in a pig house when carbon dioxide concentration in the pig house is measured. Measurements were made of the rates of decay in concentrations of a tracer gas in an occupied pig house with natural ventilation. The results of the tracer gas experiments and carbon dioxide model calculations showed a mean discrepancy of 13% for a natural ventilated pig building over ventilation rates between 0·1 and 0·3 kg/s. This indicates that estimation of ventilation rates by using carbon dioxide measurements and applying the carbon dioxide model can be a convenient technique in climatic control of pig houses with natural ventilation.
