Abstract
A coaxial ventilator (20) exchanges atmosphere between parts of a building (22) that are at differing heights. The coaxial ventilator (20) includes an outer conduit (24) that extends from an upper end (42) thereof downward to a lower end (44) thereof. The outer conduit (24) surrounds an inner conduit (62) that extends substantially the entire length of the outer conduit (24). Both the outer and inner conduits (24, 62) are open at their respective upper ends (42, 66) and lower ends (44, 68). Temperatures of atmosphere both surrounding and within the outer conduit (24) and the inner conduit (62) induce an exchange of atmosphere between the coaxial ventilator (20) and surrounding atmosphere.
Claims19
A coaxial ventilator (20) adapted for inclusion in a building (22) for exchanging atmosphere between parts of the building (22) at differing heights thereof, the coaxial ventilator (20) comprising:
- a. an outer conduit (21) adapted for being juxtaposed with at least a portion the building (22), the portion being selected from, a group consisting of:
- i. a roof (32);
- ii. a floor (38);
- and
- iii. a wall (52a, 52b), and
- the outer conduit (24) having a length that extends from an upper end (42) thereof downward, to a lower end (44) thereof;
- and
- b. an inner conduit (62) surrounded by the outer conduit (24) and extending substantially along the entire length of the outer conduit (24) with an upper end (66) and a lower end (68) of the inner conduit (62) being located near the upper end (42) and lower end (44) of the outer conduit (24),
- both the outer conduit (24) and the inner conduit (62) being open to atmosphere surrounding the coaxial ventilator (20) only at the respective upper ends (42, 66) and lower ends (44, 68) thereof, whereby responsive to temperatures of atmosphere both surrounding and within the outer conduit (24) and the inner conduit (62) simultaneously:
- i. atmosphere about the upper end (42) of the outer conduit (24) enters into one (1) of two (2) conduits (24, 62) selected from a group consisting of:
- A. the outer conduit (24);
- and
- B. the inner conduit (62);
- and
- ii. atmosphere within the coaxial ventilator (20) exits into atmosphere about the upper end (42) of the outer conduit (24) from one (1) of two (2) conduits (24, 62) selected from a group consisting of:
- A. the inner conduit (62);
- and
- B. the outer conduit (24).
A coaxial ventilator (20) adapted for inclusion in a building (22) for exchanging atmosphere between parts of the building (22) at differing heights thereof, the coaxial ventilator (20) comprising;
- a. an outer conduit (24) adapted for being juxtaposed with at least a portion the building (22), the portion being selected from a group consisting of:
- i. a roof (32);
- ii. a floor (38);
- and
- iii. a wall (52a, 52b), and
- the outer conduit (24) having a length that extends from an upper end (42) thereof downward to a lower end (44) thereof;
- and
- b. an inner conduit (62) surrounded by the cuter conduit (24) and extending substantially along the entire length of the outer conduit (24) with an upper end (66) and a lower end (68) of the inner conduit (62) being located near the upper end (42) and lower end (44) of the outer conduit (24), the inner conduit (62) having at least one (1) hole (63) formed therethrough for allowing an exchange of air between the conduits (24, 62) in at least one (1) location (64a, 64b, 64c) along the length of the outer conduit (24) where a transition in temperature about the outer conduit (24) occurs,
- both the outer conduit (24) and the inner conduit (62) being open to atmosphere surrounding the coaxial ventilator (20) at the respective upper ends (42, 66) and lower ends (44, 68) thereof, whereby responsive to temperatures of atmosphere both surrounding and within the outer conduit (24) and the inner conduit (62) simultaneously:
- i. atmosphere about the upper end (42) of the outer conduit (24) enters into one (1) of two (2) conduits (24, 62) selected from a group consisting of:
- A. the outer conduit (24);
- and
- B. the inner conduit (62);
- and
- ii. atmosphere within the coaxial ventilator (20) exits into atmosphere about the upper end (42) of the outer conduit (24) from one (1) of two (2) conduits (24, 62) selected from a group consisting of:
- A. the inner conduit (62);
- and
- B. the outer conduit (24).
