Abstract
Description
This article addresses how to heat livestock barns in harsh North Dakota winters cheaply and safely. The method chosen for critique was using rocks to retain heat from exhaust fans from barns and to have this heat returned back into the barns by reversing ventilation fans. Tweeking the test system by various means prove effective. Redesigning the barn to further optimize increased heating capabilities were successful. Humidity levels and problems of fogging or rain in the barn were absent.
