doi:10.12300/j.issn.1674-5817.2021.077

Abstract

Abstract: Taking the removal efficiencies of waste heat, ammonia, and carbon dioxide, and the mean age of air as the evaluation indicators of air distribution, the pros and cons of air distribution in two different types of animal barriers, an experimental facility and a breeding facility, were analyzed at various air change rates and exhaust outlet positions by computational fluid dynamics (CFD) numerical simulation technology. The results of selected indicators showed that ceiling air supply plus bottom exhaust outlet were suitable for the laboratory animal barrier facilities. In addition, air change rate in high-density breeding facilities should be adjusted according to the room temperature.

Key words: Animal experiment, Animal breeding, Barrier facility, Removal efficiency, Mean age of air
