Claims
- 1. A forced-air unit comprising a front cover member, a rear cover member connected to and spaced from said front cover member defining a unit housing having a depth between said cover members and a periphery, heat exchanger means extending along the substantial portion of said housing periphery, a sirocco fan rotatably mounted in said unit housing on an axis of rotation extending in the depth direction of said unit housing, said fan having a central inlet area and an annular outlet area for moving air radially outwardly of said annular outlet area and axially inwardly of said central inlet area when said fan rotates, a motor connected to said fan for rotating said fan to induce air axially into said inlet area and radially out through said outlet area, and a fan casing connected in said unit housing extending from said cover members and over said fan and having an inlet opening over said inlet area of said fan, said casing intersecting said heat exchanger means at two spaced locations thereof on said housing periphery, said fan casing defining with said front cover member an inlet space and said casing including an outlet area covering a portion of said housing periphery between said two spaced locations of said heat exchanger means defining an outlet port with said rear cover member, the remainder of said housing periphery comprising a housing inlet port for said inlet space whereby, with the rotation of said fan, a portion of air is caused to move radially inwardly of a portion of said heat exchange means through said inlet port and into said inlet space, around said fan casing in through said inlet opening of said fan casing and radially outwardly through said outlet port, said heat exchanger means disposed radially outwardly of said fan and substantially therearound and including at least one portion in said outlet port and at least one portion in said inlet port.
- 2. A forced-air unit according to claim 1, wherein said heat exchanger means comprises a single heat exchanger extending around said housing periphery with portions thereof in said inlet port and portions thereof in said outlet port.
- 3. A forced-air unit according to claim 1, wherein said heat exchanger means comprises a separate heat exchanger in said outlet portion and a separate heat exchanger in said inlet portion.
- 4. A forced-air unit according to claim 3, wherein said two mentioned heat exchangers are connected to each other through a connecting tube.
- 5. A forced-air unit according to claim 1, wherein said heat exchanger means is in thermal contact with said front and rear cover members whereby said front and rear cover members act as radiator bodies for said heat exchanger means.
- 6. A forced-air unit according to claim 1, wherein said heat exchanger means is in thermal contact with said front cover member.
- 7. A forced-air unit according to claim 1, wherein said heat exchanger means comprises a metallic tube having a plurality of fins extending therefrom, said tube adapted for receiving hot water.
- 8. A forced-air unit according to claim 1, wherein said unit housing is rectangular with said outlet port comprising one side of said rectangular unit housing and said inlet port comprising the remaining three sides of said rectangular unit housing.
- 9. A forced-air unit according to claim 1, wherein said motor means comprises a motor positioned within said central inlet area of said fan having an axle connected to said fan and aligned with the axis of said fan.
- 10. A forced-air unit according to claim 1, wherein said heat exchanger means comprises an electric heating member.
- 11. A forced-air unit according to claim 1, wherein said inlet port comprised of a portion of the periphery of said unit housing comprises two-thirds of the total periphery of said unit housing and said outlet port comprises the remaining one-third of said housing periphery.
