Sustainable Shed Solar Air Heater Entire BE 4730

Sustainable Shed Solar Air Heater Entire BE 4730 Class Prepared by: Carolyn Coffey, Ben Leppard, and Matt Rosen

Purpose -The solar air heater (SAH), along with the entire sustainable shed, got destroyed while in transit from Mc. Adams to the Aquaculture facility. Our project was to design, fabricate, implement and analyze the a new SAH for the sustainable shed.

Design ❖ Passive flow, split-channel system separated by absorber plate ➢ ➢ Inlet is perpendicular to the ground Outlet is parallel to the ground ❖ Asymmetrically tapered from outside to inside in order to fit into 21” window.

Determining Effective Heat Transfer Assumed v=0. 1 (m/s) (v=velocity of air) u can be calculated through smoking technique

Determining Heat Generation Assumed v=0. 5 (m/s) v can be calculated through smoking technique
