Referring now to the drawing, wherein like reference characters designate identical or corresponding parts throughout the several views, and more particularly to FIGS. 1 and 2, there is shown a combined wall and ventilator module:embodying the present inventioin.
The comblned wall and ventilator module comprises an open~rectangular window frame 2 mounted in an opening of a building tnot shown). The window frame 2 is composed of extruded aluminum shapes or sections and has a tra~som or an intermediate horizontal frame member 4 extending between vertical frame members of the frame 2 to define a pair of

upper and lower openings within the frames 2. The frame member 4 is positioned more closely to a bottom horizontal member of the frame 2 than to a top horizontal frame member. A pair of pans of glass 3, 3 is mounted within the upper opening on the room exterior side of the frame 2, and a thermally insulated panel l is mounted within the lower opening on the room exterior side of the frame 2. The glass pans 3, 3 and the thermally insulated panel 1 thus arranged jointly constitute a thermally insulated wall element 5 which constitutes jointly with the frame 2 a wall unit. Consumed room air is sucked into the ventilator 6 as indicated by the arrows 7 in FIG. l and then it is discharged downwardly from the intermediate horizontal frame member 4 as indicated by the arrows lO in FIG. 2.
Fresh atmospheric air is sucked upwardly from the ~rame member 4 into the ventilator 6 as indicated by the arrows 9 in FIG. 2 and then it is discharged upwardly from the frame member 4 as indicated by the arrows 8 in FIG. l. The fresh atmospheric air and the consumed room air are brought into heat-exchange relationship as they flow through the ventilator 6.
The ventilator 6, as illustrated in FIGS. 3 through ~5, includes a thermally insulated casing ll having the shape of an elongated rectangular box. As shown in FIG. 3, :
the interior of the casing 11 is divided by means of a central hollow vertical parti-tion wall 12 into lef-t and right chambers each of which is subdivided by a side , ~
.
vertical partition wall 13, 14 into interior and e~terior compartments. A heat-exchanging rotor 15 is rotatabLy mounted on the central partition wall 12 across the left and right chambers to face the interior and exterior compartments and is driven by a motor 16 (FIG. 3) via an endless belt to rotate at a relatively low velocity. The rotor 15 is of the type which is capable of exchanging both sensitive heat and latent heat at the same time.
The ventilator 6 also includes a blower or fan 17 mounted on the partition wall 13 for bringing air into the room interior, and a blower or fan 18 mounted on the partition wall 14 for discharging air outside the room.
The casing 11 has a fresh atmospheric air inlet port 19, a fresh atmospheric air outlet port 20, a consumed room air inlet port 21, and a consumed room air outlet port 22. The ports 19-21 are defined in an upper wall of the casing 11 while the port 22 is defined in an interior side wall of the casing 11. With the ventilator 6 thus constructed, the fresh atmospheric air is introduced through the intack port 19 into the casing 11 and then flows through a right zone of the rotor 15. Then the fresh atmospheric air is discharged from the outlet port 20 into the room interior.
Likewise, the consumed room air is introduced through the inlet port 21 into the casing 11 and then flows through a left zone of the rotor 15. Thereafter, the consumed room air is discharged from the outlet port 22 to the outer atmosphere. During the passage through the rotor 15, the ,, ~ . : . ~ ,, :
.: .
,.
' ~,., fresh atmospheric air and the consumerl room air exchange heat.
The fresh atmospheric air is introduced into the ventilator 6 through a fresh atmospheric air intake passage 23 (FIG. 6) while the consumed room air is discharged outside the room through a consumed room air discharge passage 24 (FIG. 7), the intake and discharge passages 23, 24 being defined in the intermedia-te horizontal frame member 4. As these passages 23, 2~ have the same construction, only the air intalce passage 23 is described below in detail.
As shown in FIG. 6, the intermediate horizontal frame member 4 has a thermally insulated construction and comprises a pair of interior and exterior frame pieces 25, 26 interconnected with connectors 27 interposed therebetween, the connectors 27 being made of a thermally insulating material. The interior frame piéce 25 has a hollow rectangular cross-section and includes a hollow hoironztal portion 28, a hollow vertical portion 29 e~tending integrally downwardly~from an exterior eage of the horizontal portion 28, a pair of L-shaped horizontal projections 30, 30 projecting exteriorly from the horizontal:portion 28 and the vertical portion 29, respectively,:and an L-shaped cover 31 secured to the horizontal and vertical portions 28, 29 to cover ~he interior side of the interior piece 25. A batten or outer horizontal frame member 32 is disposed above the upper ::

projection 30 and secured to the interior frame piece 25.
The exterior frame piece 26 includes an elongated web or body 33, an upward projection 34 secured to an upper portion of the body 33 in confronting relation to the batten 32, and a palr of upper and lower covers 36, 35 to cover the exterior side of the exterior frame piece 26.
The upper cover 36 is secured to the upward projestion 34 and the lower cover 35 is secured to the body 33. The lower cover 35 has a substantially C-shaped cross-section and projects exteriorly from the exterior surface of the thermally insulated panel 1. The upward projection 34 and the batten 32 jointly support therebetween the lower edges of the glass pans 3, 3 through gaskets. The body 33 is secured to the horizontal projections 30, 30 by means of a plurality of screws 37 with the thermally insulating connectors 27 sandwiched between the body 33 and the pro]ection 30, 30. Although not shown, the top and bottom horizontal frame members and the vertical frame members have a thermally insulated construction and each include a pair of interior and exterior frame pieces interconnected with a therma;lly insulatiDg connector interposed therebetween.
- To provide the fresh atmospheric air intake passage 23 shown in FIG. 6, a hole or opening is defined in a bottom wall~of~the lower cover 35, a pair of aligned holes or openings is defined, respectively, in the body 33 and an exteror wall of the hollow vertical portion 29, and a hole .; - 7 -.

or opening is defined in a bot-tom wall of the vertical hollow portion 29 in registry wi-th the fresh atmospheric air inlet port 19 of the ventilator 6. A series of such intake passages may be provided in which instance a partition wall (not shown) of thermally insulated material is disposed between each pair of adjacent holes. The intake passage 23 has a layer 38 of thermally insulating material provided over on the inner peripheral surface along the length thereof. More specifically, the thermally insulating layer 38 extends over the inner peripheral surface of the hollow vertical portion 29 and opposed surfaces of the connectors 27, 27. Through the intake passage 23 thus constructed, the fresh atmospheric air is introduced into the ventilator 6 and, after having been subjected to a heat exchanging relationship with the consumed room air in the rotor 15 (FIG. S), it flows into the hollow interior of the interior frame 25 through the outlet port~20 ~FIG. 7) and is flnally discharged from an air discharge port 39 into the room. The air discharge port 39 is composed of an air diffuser as shown in FIG. 7.
.
As descrlbed above, the interior of the room communicates through the intake and discharge passages 23, 24 with the outer atmospheric air. In order to avoid air exchange when the ventilator is out of operation, there may be provided in these passages 23, 24 a pair of valves to open and shut the corresponding passages 23, 24. FIG. 8 shows~one such;valve providad in the fresh atmospheric air ~ - 8 -.

intake passage 23. The valve cornprises a damper 4~
pivotably connected to the body 33 of t'ne exterior frame piece 26 and pivotable between a closing position indicated by solid lines and an opening position indicated by plantom lines. To actuate the damper 40, a vertical rod 41 and a horizontal rod 42 are disposed in the intake passage 23.
The horizontal rod 42 is pivoted at one end to the damper 40 and at the opposite end to one end of the vertical rod 41. A link 43 is pivotably connected at one end to the pivot of the rods 41, 42 and at the opposite end to a portion of the interior frame piece 25. The other end of the vertical rod 41 is operatively connected to a suitable drive mechanism (not shown) disposed in the ventilator 6.
A stopper block is pivoted to the other end of the link 43 and engages the horizontal rod 42 to prevent the latter Erom moving leEtward in FIGS. 8 and 9 when the damper 40 is in the closing position. With the stopper thus arranged, accidental air change is avoidable even when the damper is forced to pivot in the opening direction without the agency of the rods 41, 42 and the link 43. The damper 40 may be coordinated with the electric system for the ventilator 6 so that it is~forced automatically to take closing position when the supply of current to the motors of the fans 17, 18 or the motor 16 for the rotor 15 is interrupted. The damper 40 preEerably has an exterior surEace covered with a thermally insulating layer 40. As described above, the damper 40 may be disposed in the consumed room air .- 9 _ ~ :` ~ .

discharge passage 24.
The combined wall and ventilator module of the present invention has various advantages: Since the fresh atmospheric air intake passage 23 and the consumed room air discharge passage 24 are defined in the thermally insulated frame member 4, the thermally insulated wall element 5 is free of hole or opening which would otherwise cause a substantial reduction in mechanical strength. Such opening-free wall element is neat in appearance. With the intake and discharge passages 23, 24 thermally insulated by the thermally insulated layer 38, the frame member 4 as a whole gives a desired degree of thermal insulation without forming dewdrops thereon.
Although various minor modifications may be suggested by those versed in the art, it should be understood that we wish to embody within the scope of the patent warranted hereon r all such embodiments as reasonably and properly come within the scope of our contribution to the art.
