Using Smart Ventilation Approaches for Complex Environmental Issues in Farm Animal Housing
Ventilation is one of the most important approaches to achieve a desired indoor air quality and thermal environment for occupants in confined structures.In farm animal housing, intensive production, cost efficiency, working condition and environmental impacts make the issue complex, depending on many factors, such as the region climate, animal welfare and environmental regulation, etc.This paper presents some of the innovative approaches to face the challenges of low carbon and low emission ventilation as well as ventilation in hot climate regions and in continent climate regions.Two cases of new ventilation approaches are provided with on-site field measurement results.The research perspectives on complex livestock housing ventilation are included.The example of partial pit air exhaust ventilation showed that 58% and51% ammonia emissions could be removed via the pit exhaust in the two runs, respectively.For the system using combined Natural ventilation (NV) and partial pit air exhaust (PPAE), the measured results revealed that 64%-83% of ammonia emissions were via partial pit ventilation.Both systems have potential to effectively reduce ammonia emissions by connecting the PPAE with an air purification unit.
