Apparatus for drying rooms

A hand-portable room drying apparatus for use in a sealed damp or waterlogged room containing air, said apparatus for use in association with external ducting, the apparatus comprising:

• a housing in the form of a suitcase having a carrying handle, the housing including:
• a first inlet adapted to receive air in the housing from outside the room via the external ducting;
• a first outlet adapted to deliver air from the housing into the room;
• a second inlet adapted to receive air in the housing from inside the room;
• a second outlet adapted to expel air from the housing to outside the room via the external ducting;
• a first fan;
• a second fan;
• a heater;
• a system of connectable air flow ducts within the housing connecting the first inlet, the first outlet, the second inlet, and the second outlet, the system of connectable air flow ducts including a first duct and a second duct;
• and
• a valve within the system of air flow ducts operable between a first position and a second position, wherein in the first position, the system of connectable air flow ducts defines a first set of air flow paths, and in the second position, the system of connectable air flow ducts defines a second air flow path different from the first set of air flow paths;
• wherein the first set of air flow paths is adapted to simultaneously transport air both:
• along a fresh air path through at least a part of the first duct, consecutively from the first inlet, through the first fan, along the valve, through the heater, and out the first outlet;
• and
• along an exhaust path through at least a part of the second duct, consecutively from the second inlet, through the second fan, along the valve, and out the second outlet;
• and
• wherein the second air flow path is adapted to transport air through at least a part of both the first duct and the second duct, consecutively from the second inlet, through the second fan, along the valve, through the first fan, through the heater, and out the first outlet.
