| Dimensioning of air conditioning plants for animal houses is traditionally based on steady-state conditions with constant animal heat and moisture production over a 24-hour cycle, despite the fact that the heat and moisture production varies diurnally. The heat production is normally highest in daytime and lowest during the night and therefore, there will be a discrepancy between the actual and the calculated indoor temperature and humidity, when using steady state models to control ventilation rate. This article deals with the two main factors influencing on the diurnal heat production, namely the animal activity and the digestion of food. In experiments carried out over three years in respiration chambers at Research Centre Foulum, Denmark, the... |
