Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reciprocating window air conditioning system with warm radiation and, more particularly, to a reciprocating window air conditioning system with warm radiation for preventing hot flashes in the windows on the outer wall of a building in the summer and cold draft in the winter.

[0002]

2. Description of the Related Art Inside a window on the outer wall of a building, the room temperature rises due to a large amount of incident energy when the sunlight is strong in the summer, and as shown in FIG. feel it. In winter, the temperature of the window glass in contact with the outdoor atmosphere becomes low, and the cold air flows down on the glass surface,
As shown in FIG. 3 (B), cold air at a temperature considerably lower than room temperature comes into contact with the human body, causing a so-called cold draft to be felt.

In order to solve hot flashes and cold drafts, fan coil units and wall-through type air conditioning units have been proposed.

[0004]

However, the conventional fan coil unit or wall-through type air conditioning unit is
Although the air after the air conditioning treatment is blown to the perimeter portion along the outer wall or the window, the blown air mixes with the indoor air, so that hot flash and cold draft could not be completely removed. During the heating period (winter period), the warm air in the perimeter portion mixes with the cool air in the inner portion, that is, the interior zone, causing heat loss called mixing loss.

The inventor of the present invention forms an air barrier in the perimeter portion, and switches the air temperature of the barrier to a low temperature or a high temperature in accordance with switching between cooling and heating, and also changes the direction of the air flow in the barrier, so that the perimeter portion can be switched. It has been noted that the above-mentioned problems such as hot flash, cold draft, and mixing loss can be solved all at once since the air temperature can be controlled and maintained at an appropriate temperature substantially independently of the air temperature in the interior zone.

Therefore, an object of the present invention is to provide a reciprocating window side air conditioning system with warm radiation, which prevents hot flashes and cold drafts.

Referring to FIGS. 1 and 2, in the summer, low temperature air is blown downward from the window box 5 as shown by an arrow 17 and sucked in by the lower box 3. According to calculations by the present inventor, the outside temperature
Blind 19 in Fig. 2 (A) at 33.5 ^oC and room temperature of 26 ^oC
In the case of the westward window 1 with a window, if the air temperature at the outlet is 15 ^° C, the inside air temperature in contact with the glass window can be kept below 26 ^° C. With such an air temperature inside the glass window, hot flash can be almost completely removed. Figure 2 (A)
The blind 19 is not an essential requirement of the present invention.

During the winter, hot air is blown from the lower box 3 by the arrow 15
As shown by, the upper box body 5 of the blowing window sucks upward. According to the above calculation by the present inventor, the outside temperature is 2 ^° C. and the room temperature is 22 ^° C.
In the case of the structure with the blind 19 shown in FIG. 2B at that time, if the air temperature at the outlet is 45 ^° C., the inner air temperature in contact with the glass window can be kept high. If the air temperature inside the glass window is maintained at this high level, the cold draft can be removed almost completely. According to the present invention, not only the cold draft is removed, but warm air is passed through the lower box 3 at the time of heating to cause the lower box 3 to radiate warm radiation to create a sensible environment in a space near the floor on the window side. Improve. Figure 2
The blind 19 in (B) is not an essential requirement of the present invention.

In this way, the object of the present invention is to "provide a reciprocating window-side air conditioning system with warm radiation in which hot flash and cold draft are prevented".

Embodiment In the embodiment of FIG. 1, an air conditioner 11 and a switching device 13 are installed in a space above the ceiling, and the switching device 13 is placed in a lower box via a first air passage 7 and a second air passage 9 such as an air duct. It is connected to the body 3 and the window box body 5. In this example, the lower boxes 3 are linearly arranged, and the window upper boxes 5 are also linearly arranged so as to face the lower boxes 3 and face upward between the lower boxes 3 and the window upper boxes 5. Alternatively, an air barrier with a downward air flow is formed in a planar shape, and this air barrier thermally separates the air near the window from the air in the interior zone, and prevents hot flashes and cold drafts.

The temperature of the air sent to the lower box 3 in the case of warm radiation is preferably 35 ^° C.-50 ^° C., more preferably 40 ^° C.-
It was confirmed by simulation calculation that it was 45 ^° C.

By closing both windows W2 and W3, the air supply side of the air conditioner 11 is moved downward via the air supply pipe 38, the second chamber 25 of the switching device 13, the third chamber 29 of the switching device 13 and the first air passage 7. While being connected to the box body 3, the window box body 5 is connected to the second air passage 9, the third chamber 31 of the switching device 13, and the first chamber of the switching device 13.
It can be connected to the return air side of the air conditioner 11 via 23 and the return air pipe 39. That is, FIG. 7A shows a state during heating using the upward warm airflow.

In FIG. 7B, by closing another pair of windows W1 and W4 which are not in contact with any one of the first chamber 23 to the fourth chamber 31 by damper plates 35a and 35b, air conditioner

Is connected to the window upper box body 5 via the fourth chamber 31 and the second air passage 9, and the lower box body 3 is connected to the first air passage 7, the third chamber 29 of the switching device 13, and the first chamber of the switching device 13. The state connected to the return air side of the air conditioner 11 via the room 23 and the return air pipe 39 is shown. That is, FIG. 7B shows a state during cooling using a downward cold air flow.

The four windows W1, W2, W3 and W4 described above
Since the switch 13 having the four chambers 23, 25, 29 and 31 has no play space during cooling and heating, it has a feature that the space of the building can be efficiently used for installation.
