Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an air conditioning method,
In particular, the air in the lower part of the interior surface of the outer wall or the window, etc. is sucked in and controlled to a temperature close to room temperature, and then blown out into the room to perform displacement ventilation. The present invention relates to an air-conditioning method for efficiently providing low-cost comfort.

[0002]

2. Description of the Related Art Regarding the comfort of an air-conditioning environment, by actively forming a temperature stratification, a living area is always wrapped with fresh intake air, and generated in a room such as hot air from a heat source such as OA equipment and cigarette smoke. Ventilation (air conditioning) system that eliminates heat load and contaminants from the upper space without dilution or diffusion,
There is displacement ventilation system.

Conventional displacement ventilation 40
As shown in FIG. 6, a lower outlet 41 is installed at a lower corner of a wall surface in a room, and air is supplied from an air conditioner through an air supply duct 42 to the room, and the inside of the room is 0.5 m / sec or less. Of low wind speed. Air supply at low wind speeds
The living area is always wrapped with fresh air supply, and the air supply is drawn to the heating element autonomously, so the heat generated in the living area, pollutants, cigarette smoke, etc. It is excluded from the upper space without being diffused into the air, and has an excellent feature that high quality air quality can be efficiently and economically achieved in terms of energy consumption, ventilation performance, and the like. However, since the air supply to the room is performed from the lower outlet installed in the lower corner of the indoor wall, a rising phenomenon in which the warm air from the lower outlet starts rising immediately occurs and does not propagate into the room. Therefore, it has been pointed out that inconveniences such as inapplicability to heating and uncomfortable feeling caused by the high-speed low-temperature airflow 44 crawling under the occupants' feet remain.

[0004] Recently, there has been proposed an air-conditioning system that blows out the entire floor, taking advantage of the advantages of displacement ventilation. As shown in FIG. 7, the full-floor air-conditioning system 45 blows a tile carpet having air permeability into a perforated 2.
It is laid on a heavy floor 46 and receives an air supply 47 to uniformly supply a very low air velocity 48 of 2.0 cm / sec or less from the entire floor of the whole room, enabling application to heating. In order to improve indoor air quality, heat generated in the living area, pollutants and tobacco smoke, etc., are removed to the upper space without dispersing to the surroundings, while eliminating discomfort caused by airflow under the feet of the occupants. ing. As described above, the full floor air-conditioning air-conditioning system 45 has an excellent function as an air-conditioning system for the whole room, but has the above-mentioned excellent features in a room with a perimeter, a window with a small depth, a room facing a corridor, and the like. In some cases, the functions cannot be fully demonstrated.

As a countermeasure for this, means for disposing a floor-mounted fan coil unit at a lower corner of a wall surface to suck in air at about the same temperature as room temperature and blow it out to an upper portion against a load on a window portion and a cold draft. Has been taken,
A large amount of energy is consumed to improve the surface transmissivity of the walls and windows, and this is not always a reasonable method from the viewpoint of effective use of heat energy. In consideration of annual primary energy consumption in offices and the like, the proportion of transportation power required by air conditioning and the like occupies about 30% of the total energy consumption. The issue of reduction of stake has become a major issue for consideration.

On the other hand, smoking cessation in office buildings has recently been progressing, and smoking in office rooms has been shunned. For this reason, smoking in specific defined areas is recommended, and the number of cases where smoking rooms are arranged at braking spots, which are often provided at corners of buildings, is increasing. When the braking spot is also used as a smoking room, the entire braking spot often becomes cloudy, not only the view is not clear, but also the dirt becomes severe, forming a very bad air quality May be. As smoke emission measures in smoking rooms,
A method has been proposed in which a swirling updraft is generated on a table on which an ashtray is placed to rapidly exhaust tobacco smoke, but there is no established ventilation method yet. Therefore, in order to improve the air quality, the number of ventilations is extremely increased or an electric dust collector is used in many cases, and there has been a problem that the running cost is greatly increased.

[0007] As described above, the conventional air-conditioning system exhibits its function as an air-conditioning system in the main indoor part. However, the conventional air-conditioning system is compatible with a perimeter and is arranged in a room with a small depth near a window, a corridor or a braking spot. In the case of a smoking room, etc., there remains a problem that the comfort of the air environment cannot be solved functionally and economically, and an air-conditioning method that can cope with these problems has been desired.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The air conditioning method according to the present invention is basically arranged such that a lower blower fan, an air conditioning coil and a lower blower outlet are communicated with each other at a corner between an indoor surface of an outer wall and a floor surface. After controlling the temperature of the air taken in from the surface, the ventilation is performed by radially blowing out the air from the lower outlet as a low wind velocity, and the displacement ventilation is performed. The comfort of the air-conditioning environment is efficiently achieved at low cost by eliminating the influence of the feeling of airflow under the feet. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an air flow distribution diagram conceptually expressing the air conditioning method according to the present invention. FIG. 1 (a) is an air flow distribution diagram in a “heating state”, and FIG. 1 (b) is an air flow distribution diagram in a “cooling state”. is there. In the figure, 1 is a living room in a living area, 2 is a window glass provided on an outer wall, 3 is a floor, and 4 is a ceiling. An airflow 6 is formed at a corner 5 formed by the interior surface of the window glass 2 and the floor.
, And an exhaust port 8 is arranged on the ceiling 4. The lower outlet 7 is connected to a lower outlet fan coil unit 9, and an outlet duct (not shown) is connected to the outlet 8 to return to the air conditioner.

The air flow 6 from the lower outlet 7 is formed by sucking air below the window surface. In the winter “heating state” shown in FIG. 1A, cold draft has occurred on the window glass surface. The cold draft sucked by the lower blower fan 10 constituting the lower blower fan coil unit 9 also forms a lower blower fan coil unit, and the air-conditioning coil 11 performing the heating operation reaches a temperature close to room temperature. The temperature is raised. Next, the air is uniformly guided to the lower outlet 7 by the filter 12 also serving as a pressure equalizing plate.
Radially at a low wind speed of 0.5 m / sec or less.

As described above, since the air-conditioning method according to the present invention is compatible with a perimeter, during "heating" in winter, the lower blow fan coil unit removes the perimeter load from the window glass and simultaneously uses high-temperature blow. The blow-up phenomenon is avoided, and the influence of the sense of airflow under the feet is eliminated even at the window, and the ceiling 4
It realizes efficient displacement ventilation toward. And the formation of displacement ventilation,
Since the vertical airflow is formed as shown by the airflow generated by the temperature rise due to the human body temperature, the hot air from the OA equipment and the smoke of cigarettes are guided to the upper part without stirring around, and the ceiling is exhausted. Since the air is exhausted from the mouth 8, the indoor fogging is prevented and the air quality is improved.

FIG. 1B shows a "cooling state" in the summer season.
FIG. In the summer "cooling condition",
Since the sunshine load occurs on the window glass surface, the blind 13 is lowered on the window glass to reduce the sunshine load. However, the heated air forms a heat reservoir on the lower surface of the ceiling and is discharged from the exhaust port. At the same time, the rising airflow due to the heated air causes a disturbance in the airflow distribution in the room. In order to maintain displacement ventilation, it is necessary to supply a strong cold air flow,
At the same time, the air-conditioning efficiency is reduced, and at the same time, discomfort due to the high-speed cold airflow crawling under the occupants' feet is formed.

In the air-conditioning method according to the present invention, the air below the window surface is sucked in order to suppress the rising airflow caused by the heated air and prevent the airflow distribution in the room from being disturbed. The temperature-raised air sucked by the lower blow fan 10 is cooled to a temperature about 8 ° C. lower than room temperature by the cooling air-conditioning coil 11, and then cooled to the lower blow outlet 7 by the filter 12, which also serves as a pressure equalizing plate. The air flow 6 from the lower outlet 7 is guided uniformly, and the temperature of the air flow 6 from the lower outlet 7 is about 8 ° C. lower than room temperature.
The air is blown at a low wind speed of c or less. Therefore, the air layer of the perimeter maintains a normal airflow distribution in the room by forming a temperature difference with respect to the sunshine load, and secures the air conditioning efficiency of displacement ventilation.

As described above, the air conditioning method according to the present invention
At the time of "cooling" in the summer, the lower-blowing fan coil unit contributes to the improvement of air conditioning efficiency by efficiently removing the solar radiation load, and at the same time, eliminates the discomfort caused by the low-temperature airflow under the feet even at the window, thereby reducing the floor 3. , The displacement ventilation from the surface to the ceiling 4 is efficiently realized. Then, similarly to the “heating” state in winter, hot air from the OA equipment and smoke of cigarettes are guided upward without being stirred around, and are exhausted from the exhaust port 8 on the ceiling, thereby preventing indoor fogging. And improved air quality at the same time.

The air-conditioning method according to the present invention is not limited to the above-mentioned living area having a window glass, but is similarly applied to an indoor room having an outer wall without a window glass, and further includes a building provided with a system using a radiation panel or the like. It is apparent from the above description that the present invention can be effectively applied to a perimeter, such as a private room, an accommodation room, and a sickroom facing a window or a corridor with a small depth.

Next, an embodiment of the lower blow fan coil unit will be described. FIG. 2 is an enlarged view of the lower blow fan coil unit, and FIG.
(B) is a front view. In the present embodiment, the lower blower fan coil unit 9 disposed at the corner between the indoor surface and the floor of the outer wall is closed by the cover plate 21 provided in the perimeter, and the lower blower fan 10 And a coil 11. The lower blower fan 10 sucks in air such as cold draft from the indoor surface of the outer wall or the window glass from the inlet 22 provided in the top plate of the cover plate 21 and blows it out from the lower outlet 7. The air-conditioning coil 11 installed downstream of the lower blow fan 10 is
The temperature of the air flow 6 to be blown out is controlled by raising or cooling the temperature of the air sucked by the air blower 0 so as to be able to cope with the desired air conditioning.

The filter 12, which is also used as a pressure equalizing plate, is disposed between the air conditioning coil 11 and the lower outlet 7, and cleans air from the air conditioning coil 11 and simultaneously guides the air to the lower outlet 7. The uniform blowing is made possible.
The lower outlet 7 is formed of a cylindrical member 23 having a quarter circle. A plurality of openings 24 are provided on the circumferential surface of the cylindrical member 23. Since the opening 24 provided on the circumferential surface is inevitably arranged so as to radially blow out the airflow by forming the lower outlet into a quarter circle, it is possible to use a normal punching metal. Therefore, it can be easily manufactured simply by selecting the size of the opening so as to ensure a low wind speed.

In another air conditioning method according to the present invention, an air-conditioning coil and a lower outlet are disposed so as to communicate with each other at a corner between an interior surface of an outer wall and a floor surface, and the air-conditioning coil is lowered between the interior surface of the outer wall and the air-conditioning coil. A guide member that guides the air is arranged, and after controlling the temperature of the air sucked from the interior surface of the outer wall, the air is blown out radially from the lower outlet as a low wind speed, and the displacement ventilation is performed. Remove the load from the interior surface of the outer wall without using and perform replacement ventilation at the same time,
The comfort of the air-conditioning environment is efficiently achieved at low cost by eliminating the influence of the feeling of airflow under the feet. Hereinafter, an embodiment of another air conditioning method according to the present invention will be described with reference to the drawings.

FIG. 3 is an airflow distribution diagram conceptually expressing another air conditioning method according to the present invention. FIG. 3 (a) is an airflow distribution in a “heating state”, and FIG. 3 (b) is an airflow distribution in a “cooling state”. FIG. The embodiment shown in FIG. 3 has the same indoor configuration and the like as the embodiment shown in FIG. 1, and therefore only different parts will be described in detail. The lower outlet 7 is disposed at a corner 5 formed by the indoor surface and the floor of the window glass 2 and communicates with the air-conditioning coil 11. The lower outlet fan used in the above embodiment is not disposed. are doing.

In the "heating state" in winter shown in FIG. 3A, since a cold draft is generated on the window glass surface, the cold draft descending from the lower portion of the window surface is formed by the indoor surface and the floor. Air-conditioning coil 11 poured into corner 5
To reach. The cold draft that has reached the air-conditioning coil 11 that is performing the heating operation is heated and rises to a temperature close to room temperature. Since the heated air is inverted and becomes an ascending airflow, the airflow 6 from the lower outlet 7 is radiated from the lower outlet 7 radially from the lower outlet 7 at a temperature close to room temperature by a pushing force by pouring and an ascending force by heating. It is emitted at a low wind speed of 5 m / sec or less.

As described above, the other air conditioning method according to the present invention does not require fan power and is compatible with a perimeter. Therefore, during "heating" in winter, the air conditioning coil removes the perimeter load from the window glass. At the same time, displacement ventilation is realized at low cost by avoiding the blow-up phenomenon due to high-temperature blowing.

FIG. 3B shows a "cooling state" in summer.
FIG. As described above, in the “cooling state” in summer, air that has been heated by the sunshine load on the window glass surface forms an ascending airflow, but in the air conditioning method according to the present invention,
While lowering the blinds 13 to reduce the sunshine load,
Furthermore, the air below the window surface is sucked in so as to suppress this and prevent the air flow distribution in the room from being disturbed. The suction of the air is performed by effectively utilizing the natural descending force of the air due to the cooling. The air-conditioning coil 11 performs a cooling operation to cool the surrounding air to a temperature lower by about 8 ° C. than the room temperature.
When it reaches the lower outlet 7 while descending downward, it is converted to an upward tendency by heating at room temperature, and becomes an air suction force around the air conditioning coil together with the rising airflow in the room. Therefore,
The airflow 6 from the lower outlet 7 is emitted radially at a temperature about 8 ° C. lower than room temperature at a low wind speed of 0.5 m / sec or less,
The air layer of the perimeter maintains a normal airflow distribution in the room by forming a temperature difference with respect to the sunshine load, and the air conditioning efficiency of displacement ventilation is secured at low cost without using power.

As described above, the other air conditioning method according to the present invention contributes to the improvement of the air conditioning efficiency by eliminating the need for the fan power even during the "cooling" in summer and efficiently removing the solar radiation load, and at the same time, at the window. In this case, the discomfort caused by the low-temperature airflow under the feet is eliminated, and the displacement ventilation from the surface of the floor 3 to the ceiling 4 is efficiently realized. In the case of the present embodiment, similarly to the “heating” state in winter, the hot air from the OA equipment and the smoke of cigarettes are guided upward without being stirred around, and are exhausted from the ceiling outlet 8. Therefore, prevention of indoor fogging and improvement of air quality are achieved at the same time.

The other air-conditioning method according to the present invention is similarly applied not only to the above-mentioned living area having a window glass but also to an indoor room having an outer wall without a window glass, and further includes a system using a radiation panel or the like. Private rooms, accommodation rooms facing the corridors, perimeters of buildings equipped with
It is clear that the present invention can be effectively applied to each room such as a hospital room.

Next, an embodiment of the air conditioning coil and the lower outlet will be described. FIG. 4 is an enlarged view of the air-conditioning coil and the lower outlet, FIG. 4 (a) is a cross-sectional view, and FIG. 4 (b) is a front view. In the present embodiment, the air-conditioning coil 11 disposed at the corner between the indoor surface and the floor of the outer wall is closed by the cover plate 25 provided in the perimeter, and is provided below the cover plate 25. The lower outlet 7 is in communication with the air conditioning coil 11. A guide plate 26 is provided inside the cover plate 25, and guides the descending air 27 from the suction port 22 of the cover plate 25 to the air conditioning coil 11. The guide plate 26 is made of a heat insulating material so that the temperature does not change before the descending air 27 reaches the air conditioning coil 11. Although the air-conditioning coil 11 is provided as shown in the drawing at an angle at which the descending air 27 can move smoothly, the form is not particularly limited.

The suction port 22 provided on the table of the cover plate 25
, Air such as a cold draft from the interior surface of the outer wall or from the window glass is injected and blown out from the lower outlet 7. The air-conditioning coil 11 heats or cools the injected air so as to cope with desired air-conditioning, and performs necessary temperature control of the blown air flow 6.

Further, another air-conditioning method according to the present invention is basically provided with an air-conditioning coil and a lower blower fan at the corners between the indoor surface and the floor surface of the outer wall in addition to the air-conditioning method at the center of the room. After controlling the temperature of the air sucked in from the interior surface of the outer wall, the air is blown out radially from the lower outlet as a low air velocity to perform displacement ventilation in the perimeter area. At the same time, replacement ventilation is performed throughout the room to eliminate the effect of the feeling of airflow under the feet, thereby achieving the comfort of an air-conditioned environment efficiently and at low cost. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 5 is a conceptual diagram of an office or the like to which another air conditioning method according to the present invention is applied. In the present embodiment, the form of air conditioning in the office 30 having a large depth is shown. A floor floor air-conditioning system 32 is disposed in the central part 31 of the office 30, and in addition to this, a corner 5 formed at the lower part of the window glass 2 provided on the peripheral outer wall corresponds to a perimeter area 33. As in the embodiments shown in FIGS. 1 and 3, the lower outlet 7 of the airflow 6 is arranged, and the exhaust port 8 is arranged on the ceiling 4. Therefore, in the office 30, the air quality environment, which is a feature of the entire floor blow air-conditioning system 32, is improved, and a uniform and uniform temperature environment and a draft-free airflow environment are achieved.
Since the air conditioning method described with reference to FIGS. 1 and 3 is functioning in the perimeter area 33, the perimeter load is completely removed, and the improvement of air quality is efficiently improved comprehensively in the entire area within the office. The comfort of the air-conditioning environment is established at low cost. In the present embodiment, the air conditioning system provided in the center of the office has been described with the entire floor air-conditioning system. However, the air conditioning system is not limited to this, and other air conditioning systems may be used. There is no restriction on recruitment.

As described above, the air conditioning method according to the present invention
A lower blow fan, an air conditioning coil, and a lower blow outlet are communicated with each other at the corner between the interior surface of the outer wall and the floor surface, or only an air conditioning coil is arranged to control the temperature of air taken in from the interior surface of the outer wall. Later, displacement ventilation is performed by blowing out radially from the lower outlet as a low air velocity airflow, so the fan power is reduced and the load from the indoor surface of the outer wall is removed, and at the same time, the replacement ventilation is performed, and the perimeter is replaced. While purifying the indoor air quality with less response and less depth, the comfort of an air-conditioned environment is achieved efficiently and at low cost.

In another air conditioning method according to the present invention, since the above-described air conditioning method and the air conditioning method for the central portion of the room are added, the power of the fan is reduced to remove the load from the interior surface of the outer wall. In addition, replacement ventilation that eliminates the influence of airflow under the feet is performed throughout the room, thereby purifying the indoor air quality and efficiently achieving the comfort of an air-conditioned environment at low cost.

Although the air-conditioning method according to the present invention has been described in detail based on the embodiments, the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the invention. Of course, changes are allowed.
