Dwelling heating and air conditioning system

A fully sealing register assembly, comprising:

• an exterior register frame construction for adapting to different sized duct openings;
• an inner register unit having an outer frame which mates with the inner sides of said exterior frame;
• said inner register unit including an array of inner vanes or blades for selectively shutting off the flow of air through the register assembly, said inner vanes pivotally attached at each end to the inner facing sides of said outer frame of the inner register unit, said inner vanes being pivoted into fully sealing engagement with the adjacent inner vanes;
• and
• means for actuating said inner vanes from an open configuration wherein said inner vanes are spaced apart and parallel with one another, to the fully sealed configuration.

A sealing register assembly, comprising:

• an exterior register frame construction for adapting to different sized duct openings;
• an inner register unit which fits within said exterior register frame;
• said inner register unit including an array of inner vanes or blades for selectively shutting off the flow of air through the register assembly, said inner vanes pivotally attached at each end to the inner facing sides of said outer frame of the inner register unit, said inner vanes being pivoted into sealing engagement with the adjacent inner vanes;
• and
• means for actuating said inner vanes from an open configuration wherein said inner vanes are spaced apart and parallel with one another, to the sealed configuration.

A fully sealing register assembly, comprising:

• an exterior register frame having means for adapting to duct openings, said means comprising:
• extruded L-shaped side members;
• and
• four corner members;
• said corner members mechanically interfitting with said side members to form a rectangular exterior frame, and said exterior frame being provided with resilient strips for sealing to walls of a building in which said register assembly is to be mounted;
• an inner register unit having an outer frame which mates with the inner side of said exterior frame;
• said inner register unit including an array of inner vanes or blades for selectively shutting off the flow of air through the register assembly, said inner vanes pivotally attached at each end to the inner facing sides of said outer frame of said inner register unit, said inner vanes being pivoted into fully sealing engagement with the adjacent inner vanes;
• and
• means for actuating said inner vanes from an open configuration, where said inner vanes are spaced apart and parallel with one another, to the fully sealed configuration.

• and
• means for actuating said inner vanes from an open configuration, where said inner vanes are spaced apart and parallel with one another, to a fully closed configuration;
• said means for actuating said inner vanes being a servo driven unit powered by a self-contained power source, said power source including batteries and a generator and an impeller to recharge said batteries.

A fully sealing register assembly, comprising:

• an exterior register frame;
• and
• an interior register unit having an outer frame which mates with the inner side of said exterior frame;
• said inner register unit including an array of inner vanes or blades for selectively shutting off the flow of air through the register assembly, said inner vanes pivotally attached at each end to the inner facing side of said outer frame of said inner register unit, said inner vanes being pivoted into fully sealing engagement with adjacent inner vanes;
• said outer frame of said inner register unit including walls defining an opening, said walls having a perpendicular inner blade ridge or shoulder, the perimeter of said inner blade ridge facing the inner vanes having additional sealing means.
