分析试验

Based on the model calculation,an FAPP ventilation system was madein Beijing Poultry Breeding Company.Through running test and a series ofphysical and chemical characteristic measurement,the distribution of flowspeed in length,and breadth was given.The average temperatureand rel-ative humidity,the amplitude of T and RH per day of 30 days in winter,and instantaneous T and RH in 24 hours wre measured in FAPP house,com-paring house and outside,the result shew that FAPP ventilation system wassuperior to comparing house.The dust concentration and microrganism con-tent were also measured in the rearing piriod of poultry,the value in FAPPhouse was junior to comparing house.
