Abstract:
In the attic or uppermost interior space of a building having a standard attic floor, an inside roof deck, exposed rafters with free lower edges, and supply or return air passageways to and from box end eaves where the rafters meet the standard attic floor; a loft or upper attic floor is placed in the uppermost part of the attic, running from one end of the building to the other above the standard attic floor; a heat barrier sheet material is fastened to the loft or upper attic floor and the free lower edges of the rafters from the loft or upper attic floor to the standard attic floor, thus forming airflow channels between the rafters, the roof and the heat barrier material; a wall or partition is placed in the center of the space formed above the loft or upper attic floor to create two spaces; a blower is positioned in said partition having an input side connected with a first area and an output side connected with a second area; an evaporator coil is positioned adjacent the input side of the blower; the blower drawing hot air from the first area above the attic floor, through the evaporator coil, through the blower input side and out the output side into the second area of the loft or upper attic floor, through te boxed eaves to the other end of the building, and up through the formed channels, picking up solar heat from the roof, into the first area of the upper attic floor and back to the blower in a closed loop; a refrigerant is used to capture the BTUs absorbed by the evaporator coil; a compressor then converts this warm vapor to hotter compressed vapor, and transfers these BTUs to a condenser where the latent heat can be used to heat a house, building, or water before returning as a liquid to the evaporator to be recycled.
