Warm Environment Control of Closed Cowshed

The environmental requirements of fatten cowshed was introduced first, such as air temperature, humidity, airflow velocity and illuminance. Measures of warm environment control, to meet the need of raising fatten oxen in closed cowshed in winter of north China were researched. In winter of north China, main environment control facilities for heat preservation and raising temperature is applying pneumatic solar heating system. Through monitoring the environmental parameters of the solar heating cowshed in the coldest months , it is concluded that applying pneumatic solar heating system with humidity discharging to the closed cowshed for raising fatten oxen in cold north China is completely feasible , and the economic benefit is obvious , so this kind of cowshed will have a bright prospects for spreading.
