Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a common ventilation method and common ventilation duct structure mainly implemented in high-rise apartment buildings, and more particularly, to a common ventilation duct structure implemented in high-rise apartment buildings, and more particularly, to Common ventilation methods and common ventilation duct structures implemented in high-rise buildings in areas where outdoor units or ventilation ports and exhaust ports for each dwelling unit would be damaged by rain or snow and become unusable if installed outdoors. Regarding.

BACKGROUND OF THE INVENTION Conventionally, in high-rise housing complexes, unless a central heating and cooling system is used, an outdoor unit for air conditioning is generally installed on the balcony of each dwelling unit. The ventilation and exhaust ports of each dwelling unit are also generally provided as holes that penetrate the wall at predetermined positions of each dwelling unit and open to the outside.

Conventionally, the ducts installed in large buildings and high-rise buildings are generally air-conditioning ducts for central cooling and heating (Japanese Patent Publication No. 48-22931). Ducts are also known (1985).
(No. 0-147453), but this serves only as a substitute for a chimney.

Problems to be Solved by the Invention In buildings located in areas with heavy snowfall, outdoor air conditioning units installed on balconies are either completely useless because they are buried under snow, or the air inlets and outlets are blocked by rain or snow. Usually, it freezes and malfunctions, making it unusable. Therefore,
It is considered inappropriate to place the outdoor unit on a balcony or attach it to an outside wall. Therefore, deciding where to install and use the outdoor unit has become an important problem to be solved.

Similarly, if the outside air intake vents and exhaust vents, which are essential for the daily life of each dwelling unit, are simply penetrated through the wall and opened to the outdoors, the outdoor openings will freeze and become blocked by snow and rain. Since they are useless if they are stored away, deciding where to install them and make them useful is a problem unique to buildings in snowy areas.

Means for Solving the Problems (Part 1 Invention) As a means for solving the problems of the prior art described above, there is a communal ventilation method for high-rise buildings according to the present invention.

As shown in the example in the drawing, an atrium ventilation duct 2 is installed from the first floor of a high-rise building 1 to the roof floor, with an inlet duct 2a for taking in outside air and an exhaust duct 2a).
Installed as a composite structure consisting of 2b, introduction side duct) 2
A configuration in which outside air is taken in and used for intake of outside air to each dwelling unit, exhaust side duct 2b is used to exhaust air from each dwelling unit, and space for installing an air conditioning outdoor unit 3, etc. is secured within the ventilation duct 2. And so.

Function: The ventilation duct 2 that extends from the first floor of the building 1 to the roof floor is provided as a composite structure consisting of an inlet duct 2a for taking in outside air and an exhaust duct 2b, so each duct 2a,
The air flowing through 2b can be used rationally and efficiently. That is, fresh outside air from the inlet duct 2a can be taken in through the ventilation openings and used as air essential for daily life in each dwelling unit. Dirty air, moisture, odor, etc. from each dwelling unit can be exhausted to the exhaust side duct 2b.

In addition, since the outdoor unit 3 is installed inside the ventilation duct 2, the outdoor a3 is not directly exposed to rain or snow, and there is no chance that the outdoor a3 will be covered with snow, or that the air inlet/outlet may freeze and become blocked, resulting in machine running problems. There is no need to worry about it happening.

Furthermore, the air temperature inside the ventilation duct 2 is slightly higher than the outdoor air temperature even in the middle of winter, and the air inside the exhaust duct 2b is even higher due to the exhaust temperature from each dwelling unit. By using these air temperatures for cooling or heating, the outdoor unit 3 etc. can be operated rationally and economically.

(ITJ of 2.3) Same <As a means to solve the above-mentioned problems of the prior art, the duct structure for common ventilation of high-rise buildings according to the present invention, as shown in the embodiment in the drawings, In the utility space 4 of each residential unit of the building 1 or in its vicinity, a ventilation duct 2 with an atrium extending from the first floor to the roof floor is installed as a composite structure consisting of an inlet duct 2a for taking in outside air and an exhaust duct 2b. Provided, both ducts) 2a
, outdoor 41 for air conditioning on the partition wall 2C that partitions 2b! J!
3 was installed. Also.

The duct 2a on the inlet side is provided with a ventilation port for taking in outside air from each dwelling unit, and the duct 2b on the exhaust side is provided with an exhaust port for the bathroom, toilet, kitchen, etc. of each dwelling unit.

In addition, in the common ventilation duct structure of the above-mentioned high-rise buildings,
Another feature is that a blower fan 5 for taking in outside air is installed at the top of the inlet duct 2a for taking in outside air, and an exhaust fan 6 is installed at the top of the exhaust duct.

Effects: Humidity generated in the bathroom 7 of each dwelling unit, odor from the toilet 8, hot air generated from the oven in the kitchen 9, etc.

By discharging from each exhaust port to the exhaust side duct (2a), it is possible to prevent the neighborhood nuisance that is typical of apartment complexes. Similarly, since the outdoor unit 3 for air conditioning is also installed within the duct 2, there will be no problem of noise or vibration bothering the neighbors.

Of course, the outdoor unit 3 and ventilation opening installed in the ventilation duct 2,
Since the exhaust port is not directly exposed to rain or snow, there is no need to worry about snow damage or freezing, and the exhaust port can function well throughout the year. Also,
Regarding the outdoor unit 3, for cooling in summer, heat exchange (heat radiation) can be performed efficiently and economically by using the fresh air taken into the inlet-side duct 2a. On the other hand, for heating in winter, heat exchange (
heat absorption) can be carried out efficiently and economically.

The exhaust side duct (2b) of the atrium can exhaust air by a so-called chimney effect of natural ventilation, but forced exhaust is also performed by an exhaust fan 6. Although the exhaust action of the exhaust side duct 2b can be expected to induce the intake of outside air into the introduction side duct 2a, forced intake is also performed by the blower fan 5.

Example The illustrated invention will now be described in detail.

Figure 1 shows each residential unit 10 in the plan shape of a high-rise building 1.
Bathroom 7. Toy 981In the utility space where the kitchen 9, etc. are concentrated, especially in the location ff1 adjacent to the toilet 8 (however, this is not limited to the location), an atrium ventilation duct 2 is installed from the first floor to the rooftop floor N. It shows.

As shown in detail in FIG. 2, the ventilation duct 2.

It is provided as a composite structure in which an inlet duct 2a for taking in outside air and an exhaust duct 2b are combined. The lower ends of the inlet duct 2a and the exhaust duct 2b are drawn horizontally at a height of approximately 3 m above the ground (G, L) as shown in Figure 2, and are opened to the atmosphere to create an effective atrium. is showing. This is to prevent the lower end opening of the ventilation duct 2 from being blocked by the snow accumulation by predicting the maximum snowfall amount to be about 3 m.

A blower fan 5 is installed at the top end of the introduction-side duct 2a to take in outside air. Further, an exhaust fan 6 is installed at the top of the exhaust side duct 2b to perform forced exhaust. The details are shown in Fig. 3. First, the top of the ventilation duct 2 is designed to have a height H of about 3 m from the roof floor N of the building 1 so that it will not be buried in snow. Then, a snow protection tower 12 is installed at the top of the ventilation duct 2.

A ventilation fan 5 and an exhaust fan 6 are installed inside the ventilation opening formed by the louver 13. Each fan 5.6 is installed on a base plate 15 using anti-vibration rubber 14. However, it is also possible to omit the exhaust fan 6 and perform exhaust by natural ventilation (chimney effect). Alternatively, by using a powerful exhaust fan 6, an attraction effect can be exerted on the inlet side duct 2a, thereby making it possible to implement the MIi system by omitting the ventilation fan 5.

In the ventilation duct 2, an outdoor unit 3 for air conditioning of each dwelling unit is installed on a partition wall 2C that partitions an inlet duct 2a and an exhaust duct 2b. In summer, each dwelling unit 10 is efficiently cooled by heat exchange (radiation) with outside air taken into the inlet duct 2a.

In addition, in winter, the outdoor unit 3 is configured to perform heat exchange (heat absorption) using the exhaust gas rising through the exhaust side duct 2b.
Perform efficient heating. This is because the exhaust air is mixed with hot air discharged from each dwelling unit 10 and is somewhat warm. However, the temperature of the outside air taken into the inlet duct za is
Since the temperature is about 2 to 3 degrees Celsius higher than the cold wind outdoors, heating can be performed by heat exchange (endotherm) using the temperature of the outside air as it is.

The installation position of the outdoor unit 3 is in front of the soundproof inspection door (airtight door) 11 installed on the wall of the dwelling unit 10 on each floor of the building 1, to facilitate maintenance and replacement, and to reduce the noise emitted by the outdoor unit 3. The configuration is such that no vibrations or vibrations reach each dwelling unit 10 at all. Therefore, there is no need to worry about pollution caused by the outdoor unit 3 in the neighborhood.

The introduction side duct) 2a is also opened with an intake port (ventilation port) for ventilation air required for the residential units 10...K on each floor. However, the illustration of the ventilation opening was omitted.

On the other hand, the exhaust ports of the bathroom 7, toilet 8, and kitchen 9 in which a gas stove, oven, etc., of the dwelling units 10 on each floor are located are opened on the exhaust duct 2b side.

However, illustration of the exhaust port is omitted. In other words, each dwelling unit lO...
・The humidity, odor, heat, etc. emitted by people's lives are
All of the gas is discharged to the exhaust side duct) 2b.

The top of the ventilation duct 2 is connected to the tower 12 (Fig. 3).
, or by opening sideways (see Figure 2),
It prevents snow and rain from falling. Therefore, the outdoor unit 3, ventilation ports, and exhaust ports are never exposed to snow or rain.

Therefore, there is almost no need to worry about freezing.

As described in detail in conjunction with the embodiments, the effects of the present invention are as follows, and according to the common ventilation method and common ventilation duct structure for high-rise buildings according to the present invention, the outdoor unit 3 for air conditioning or each dwelling unit 10 All of the problems unique to snowy countries, such as ventilation and exhaust vents being buried under snow, or blocked by air circulation due to freezing due to snowfall or rain, are eliminated, and a comfortable living environment can be ensured.

In other words, there is no problem of nuisance to the neighbors due to the noise and vibration of the outdoor unit 3, and the humid odor and hot air emitted by each dwelling unit 10 during daily life are also removed high into the sky through the exhaust side duct 2b, and do not cause any nuisance to the neighbors. In this way, the indoor ventilation of each dwelling unit (10) is maintained well regardless of the season, summer or winter, resulting in excellent livability.

Furthermore, an outdoor unit 3 for air conditioning installed inside the ventilation duct z
This makes it possible to perform economical heating and cooling by efficiently utilizing the outside air taken into the inlet duct 2a or the heat of the exhaust gas rising through the exhaust duct 2b.
