Ventilation Rates and Gaseous Emissions from Naturally Ventilated Dairy Houses
Biosystems Engineering, 2003 Abstract The ventilation rate, the emissions of ammonia (NH 3 ) and methane (CH 4 ), the temperature and the relative air humidity were determined in four naturally ventilated dairy houses with an eave to ridge ventilation. Additionally different climatic data (wind velocity, wind direction, temperature, relative air humidity) were measured in the ...
