ABSTRACT:
An apparatus and method for heating and ventilating a farm enclosure. The apparatus includes an energy exchange unit for preheating fresh intake air delivered to the enclosure. The unit has a first air manifold on its upper end including a fresh air intake duct and an exhaust air duct. The unit also has a second air manifold on its lower end which has an intake section and an exhaust section. A turbulation baffle is held within the unit between the first and second air manifolds. The intake section of the second air manifold communicates with the fresh air intake duct of the first air manifold through a plurality of intake baffle sections. The exhaust section of the second manifold communicates with the exhaust air duct of the first air manifold through a plurality of exhaust baffle sections. The intake and exhaust baffle sections are arranged relative to one another creating heat exchange between the two. A first air moving device communicates with the unit for drawing fresh air through the fresh air intake duct of the first manifold, through the intake baffle sections, and out the intake section of the second manifold. A second air moving device communicates with the unit to draw air from within the farm enclosure, through the exhaust section, through the exhaust baffle sections, and out the exhaust duct. One embodiment of the unit also includes a pressurized water clean out system for cleaning out the turbulation baffle.
