Contaminant-removal efficiencies in a model barn using a displacement ventilation system and a conventional supply slot system.

Author(s) : IRWIN D. R., BESANT R. W.

Summary

A model piggery barn in a laboratory was instrumented to measure air speed, air temperature, and tracer gas concentrations. Two ventilation systems were investigated: displacement ventilation and a conventional, high-wall, slot air supply system. The results showed that the displacement ventilation system was substantially better than the slot inlet system at removing airborne contaminants and for cooling. In addition, the temperature ratios for cooling were found to be significantly better for the displacement system, especially as the difference between inside and outside air temperatures increased.
