Abstract:
A portable assembly for drying an enclosed space at an elevated height above ground level comprising:an energy exchange unit, said energy exchange unit having, an ambient air inlet for the introduction of ambient air; an exhaust air inlet for the introduction of moisture laden exhaust air from an enclosed space, said moisture laden exhaust air having thermal energy; a heat exchanger accepting said ambient air from said ambient air inlet and said moisture laden exhaust air from said exhaust air inlet, said heat exchanger having a plurality of first discrete channels for the passage of said ambient air and a plurality of second discrete channels in alternating arrangement with said first discrete channels for the passage of said moisture laden exhaust air in counterflow to said ambient air, thereby preheating said ambient air, said heat exchanger having an exhaust air outlet for venting said moisture laden air to the atmosphere and an ambient air outlet; a heating means for further heating said ambient air; conduit means for directing said heated ambient air to said enclosed space; a first propulsion means for transporting said ambient air from said ambient air inlet to said enclosed space; conduit means directing said exhaust air to said atmosphere; and a second propulsion means for transporting said exhaust air from said enclosed space to said atmosphere.
