Abstract


In the 1950s , foreign veterinary workers to study a variety of infectious diseases , began to find and not trying to keeping healthy animals as experimental animals infected . SPF animals do not carry a specific pathogen , can meet the requirements of the many trials , the World Health Organization to the world of recommendation, take the the SPF animal as animal raw materials for human and veterinary vaccines . The SPF chickens came into being , but for the SPF chicken farming environment has been a lack of corresponding research . SPF chicken farming is very high environmental requirements , such as the number of ventilators , pressure , temperature , air velocity , especially CO2 volume concentration and dust particle concentration . The simulation study on the the SPF chicken coop environment is also very necessary . This paper aims at the analysis of the simulation results under the influence factors , the trend of clean indoor air . In the form of the best airflow to save energy by reducing the amount of air or air velocity . Cold SPF farms biological clean room simulation study to explore a the SPF chicken farms biological clean room early in the design Airflow Pattern reasonable . Simulation of the area of the exhaust outlet , the outlet area , breeding layer height from the ground , both ends of the outlet size , the location of the outlet and air velocity airflow . Gives the optimal design of the SPF farms . First, create a mathematical model of the SPF farms biological clean room , Airpak software has been simulated on the the SPF chicken farms biological clean room ventilation system indoor air , indoor air temperature , velocity , CO2 concentration field , dust particle concentration , the concentration of colonies field . Combination of norms, the reasonableness of the simulation results were analyzed. Second , the influencing factors on the SPF chicken farms biological clean room such as the exhaust outlet size , outlet size , the breeding layer height from the ground , both ends of the outlet size , outlet location and outlet speed simulation and analysis . The results show that : the impact of the above factors on the air distribution , the better airflow organizational forms can be obtained by changing the influencing factors , to meet regulatory requirements and achieve energy saving .
