ト１０を経て外気吹出口５より室内に吹出される。This kind of floor-standing ventilation system with a heat exchanger is constructed as shown in Figs. Exhaust air flow B from the room passes through the outside air suction chamber 7 formed inside the outer casing 1, the outside air side filter 8 provided in this chamber, and the internal heat exchanger 4. After heat exchange between the air and the air, the air is blown into the room from the outside air outlet 5 via the outside air supply chamber 9 and the blowout duct 10.

なっている。On the other hand, the indoor dirty exhaust air flow B is sucked into the indoor air suction port 11 provided at the lower part of the outer casing 1, and is transferred to an indoor air suction chamber 12 and an indoor filter 13 provided in this chamber.
It enters the above-mentioned heat exchanger 4, where it exchanges heat with the purified fresh farm air outside air A, and then passes through the exhaust chamber 14 formed in the outer casing 1 and the exhaust blower chamber 15 to the outside. The air is discharged to the outside through an exhaust port 16 provided at the bottom of the outer casing 1 by an exhaust blower 3 located at the bottom of the housing.

全体の換気を低下させる原因となっていた。In the vertical type, the outside air supply chamber 9 and the outside air blowing duct 10 are configured at right angles as shown in FIG.
Therefore, the pressure distribution in the air outlet duct 10 is higher than that in the upper layer C-C and the lower layer D-D', and therefore the flow velocity distribution at the outside air outlet 5 is shown in Figure 4. As a whole, there was a tendency for the dog to move downwards, and this caused the ventilation of the entire room to decrease.

したもので、特にこの考案の場合の上記外気吐出口部は
以下の実施例のように構成されている。This idea was designed to improve the stability of the entire device during installation, and also to eliminate the drawbacks of the above-mentioned conventional devices. It is structured as follows.

よってさらに改善しているものである。In other words, the outside air outlet section E in this device shown in FIG. By forming the core in the shape of a tapered nozzle, the flow velocity distribution of the outside air blown from the air outlet 5 is improved so that it curves upward as shown in the figure, By providing an auxiliary current plate 22 as shown in the figure, the change in wind direction is further improved by this current plate 22.

また第６図は上記外気吹出口５から吹出される外気流を

より図示イ。FIG. 6 shows another embodiment of this invention in which the outside air flow blown out from the outside air outlet 5 can be selected in a desired direction indoors. A rectifying plate 23 for changing the wind direction is provided slightly closer to the light end of the exit portion E, and the angle of inclination of the rectifying plate 23 for changing the wind direction can be selected as shown in the figure.

口、への各状態に室内に吹出される外気流を適宜その所

。The outside airflow blown into the room can be appropriately set in the desired direction for each condition.

その他第３図中の１７は上記フィルター１３および熱交

This is an opening/closing door provided for attaching/detaching the heat exchanger 4 and cleaning the suction side of the heat exchanger 4 in this section.

この考案の換気装置は以上のように構成しているので、
装置全体の重心位置が外筐の最下低部に位置することに
なり、したがって装置の据付は状態での安定性が良く、
これにより据付は占有床面積の減少を計れるばかりでな

能になる等の利点を有するものである。The ventilation system of this invention is constructed as described above, so
The center of gravity of the entire device is located at the lowest point of the outer casing, so the installation of the device is stable and stable.
This not only reduces the floor space occupied by the installation, but since the outside air outlet into the room is formed in a tapered nozzle shape, the distance that the outside air reaches into the room can be increased. Moreover, by selecting the rectifying plate for changing the wind direction provided in the core, it has the advantage that outside air can be supplied in a desired direction inside the room.
