A Laboratory Facility for Teaching Principles of Ventilation of Agricultural Structures

ABSTRACT A4.25 m X 4.25 m x 2.40 m walk-in laboratory facility for demonstrating the principles of heating, cooling, and ventilating animal and plant production facilities is described. The model is multipurpose allowing the instructor or student to demonstrate or test the performance of a wide range of heating and ventilation system configurations including positive and negative pressure ventilation, ventilation air waste heat recovery, and evaporative cooling. Many educational objectives which can be met using the facility are also identified.
