Abstract
A uni-directional valve arrangement placed in a predetermined location between a habitable enclosure and a heating or cooling system which is exposed to outdoor temperatures prevents air of undesirable temperature in the system from passing into the enclosure by gravity flow.
Claims2
In a building construction embodying a habitable enclosure, the combination of
- a temperature varying system for maintaining a predetermined temperature in said enclosure,
- a housing for said temperature varying system which housing is disposed as to be subject to outdoor temperature influences,
- an upper register constituting an opening for passage of air between the upper portions of said habitable enclosure and said housing, and
- a lower register constituting an opening for passage of air between the lower portions of said habitable enclosure and said housing,
- a mechanical shutter arrangement interposed in at least one of said registers and being operable to block passage of air between the habitable enclosure and the interior of said housing,
- a solenoid device for actuating said mechanical shutter between open and closed positions, and
- means for actuating said solenoid device upon operation of said temperature varying system.
