The use of solar heated attic air is an area of increasing interest in commercial poultry production. Attic inlets satisfy the demand for alternative heating while being simple to implement in an existing poultry house. However, little attention has been given to the configuration of the attic space and its influence on thermal energy extraction. This issue was approached in a threefold manner: i.) test case experimental data for the operation of attic inlets in an east-west oriented commercial broiler house was recorded, ii.) a two-dimensional computational fluid dynamics (CFD) attic inlet ventilation model (AIVM) was developed and verified using the experimental data, and iii.) the simulation was used to investigate the efficiency of attic inlet system improvements. The simulation demonstrated that the strategic placement of a simple diverter and an inlet riser may increase thermal energy extraction by 40% over the measured attic inlet system.
