Air make-up unit
First Claim
1. An air make-up system comprising:
- (a) a frame building having a standard exterior wall with vertical studs having standard horizontal distances therebetween, said wall being of standard or greater thickness;
(b) an elongated metal casing mounted in an opening in said exterior wall between a pair of said studs and having a depth no greater than the thickness of said wall;
(c) an air intake housing having a tubular forward portion surrounding said casing and extending inwardly in close sliding telescoping relation and having an imperforate shielding wall outside said exterior wall and extending downwardly and outwardly from the upper portions of said housing;
(d) said housing including a generally horizontal screen member extending inwardly thereacross from the lower portions of said imperforate wall toward said tubular portion of said housing to admit outside air into the interior thereof;
(e) side, top and bottom wall structure within said casing defining an interior air chamber within said casing and open at the front and rear thereof;
(f) a rotary blower mounted within said air chamber and having an air-intake in communication with the interior of said housing and having a tangential discharge throat extending horizontally and inwardly therefrom;
(g) at least one electrical heating element mounted within said blower throat to warm the air driven thereacross by said blower;
(h) a vertical wall extending longitudinally of said casing and across the interior of said chamber and around said blower throat and sealing the interior of said housing from the interior of said building except for through said blower throat;
(i) insulation within said vertical wall completely surrounding and insulating the portions of said throat in which said heating element is mounted and insulating the interior of said housing and the outside air from the interior of said building;
(j) insulation within said side, top and bottom wall structure defining said chamber and completely insulating the outer surfaces of said walls and their surrounding wall structure from the heat generated by said heating element;
(k) a controllable electric motor mounted within said chamber and connected to said rotary blower in driving relation for driving the same and thereby causing a positive air pressure to be built up within said frame building; and
(l) means for energizing said heating element as desired.

Abstract
Disclosed is an air make-up unit mounted within the confines of a conventional outside wall of a frame building between the 16" on-center studs. The unit includes a rotary blower with a horizontal tangential discharge, the latter having heating elements therein and being encased in a vertical wall of insulation which extends within an insulated air chamber defined by a telescoping outer casing. Positive air pressure is maintained within the building by air-pressure-sensitive controls located within the building and controlling the two-speed motor. The latter is thermostatically controlled to be operated at a slower speed when colder weather prevails. It is also controlled and energized by a humidistat located within the building to force outside air into the building and diminish the humidity therein when needed.

16. An air make-up unit comprising:
-
(a) an elongated metal casing constructed and arranged to be mounted within an opening between the studs of a standard exterior wall of a building; (b) said casing having a length less than the spacing between the studs of such a standard exterior wall of a building and having a depth substantially no greater than the thickness of such a wall; (c) an air intake housing having a tubular forward portion surrounding said casing in close sliding telescoping relation and having an imperforate end wall extending downwardly and outwardly from the upper portions thereof; (d) said housing including a generally horizontal screen member extending inwardly thereacross from the lower rear edge portions of said imperforate wall toward said tubular portion to admit outside air into the interior of said housing; (e) side, top and bottom wall structure within said casing defining an interior air chamber open at the front and rear ends of said casing; (f) a rotary blower mounted within said air chamber and in communication with the interior of said housing and having a tangential discharge throat extending horizontally and forwardly therefrom; (g) at least one electrical heating element mounted within said blower throat to warm the air passed therethrough by said blower; (h) vertical wall extending longitudinally of said casing and across the interior of said chamber and around said blower throat and sealing the interior of said housing from the discharge of said blower throat except for through said blower throat; (i) insulation within said vertical wall completely surrounding and insulating the portions of said throat in which said heating element is mounted and insulating the interior of the housing from the opposite side of said vertical wall; (j) insulation within said side, top and bottom wall structure defining said chamber and completely insulating the outer surfaces of said walls from the heat generated by said heating element; (k) a controllable electric motor mounted within said chamber and connected to said rotary blower for driving the same as desired to cause a positive air pressure to be built up within such a building when said casing is so mounted; (l) means for energizing said heating element as desired. - View Dependent Claims (17, 18, 19, 20, 21, 22)
