TUBEWALL: a passive solar thermo-siphoning, field-fabricated, water storage wall system
- Miami Univ., Oxford, OH
The basic component of TUBEWALL is a water-filled thin-wall cylindrical tube with an insulating foam vertical partition insert that divides the inside of the tube into a thin collector water compartment (solar side) and a larger storage water compartment (room side). The two compartments are connected at the top and bottom by means of circulation holes in the foam partition. When the sun strikes the solar side of the tube, the thin layer of collector water is heated, thermosiphons through the top opening in the partition into the larger storage compartment on the room side, and is replaced with cool water drawn from the bottom of the storage through the bottom hole in the partition. Night back-siphonage is prevented by a thin flap valve over the top circulation hole. The tubes may by used between wall studs having a low-cost fiberglass/tedlar double glazing. The tubes can be covered on the room side with drywall and heat transferred to the living space by indirect radiation, and either natural air convection through top and bottom vent slots or by fan. Alternatively, the tubes can be left exposed for direct radiation.
