TECHNICAL FIELD OF THE INVENTION
The present invention relates to a house environment purification system that achieves maintenance and purification of a house environment, and more particularly, performs purification processing of outside air taken into a house, and places outside air after the purification processing into the house. The present invention relates to a house environment purification system that achieves maintenance and purification of the house environment by supplying the same.
[0002]
[Prior art]
The recent development of highly airtight housing has led to a problem of deterioration of the environment in the house due to insufficient ventilation, while improving air conditioning efficiency.
One example of the deterioration of the environment in a house is sick house syndrome caused by volatile chemical substances contained in wallpaper, plywood adhesive and the like being released into the house over time. As one of the methods for removing volatile chemical substances that are the causative substances of this sick house syndrome, there is a method utilizing the adsorption characteristics of charcoal and the like, and various methods have been proposed.

[Patent Document 2]
JP 2001-248886 A ([0016]-[0018] FIGS. 1 and 6)
[0004]
In Patent Literature 1, the charcoal is used in the following manner, and the volatile chemical substance is adsorbed on the charcoal, thereby preventing the volatile chemical substance from volatilizing and diffusing into the house. 1) Fine charcoal powder is mixed into the interior material of a house (for example, an interior vinyl cloth), an adhesive, and a paint. 2) Provide a charcoal layer in the middle of the piping of the air conditioner that circulates air in the house. 3) An energy-saving health layer including a charcoal sheet is provided on the wall ceiling floor facing the outside air of the building.
[0005]
Further, in Patent Document 2 described above, a layer of a coating film containing charcoal powder is formed on the inner surface of a duct of an air conditioner that circulates air in a house, and harmful gases such as ammonia and formaldehyde (volatilization) in the air passing through the duct are formed. Chemical substances).
[0006]
[Problems to be solved by the invention]
However, these inventions have been made in consideration of the removal of volatile chemical substances generated in a house, and there has been no thorough measure against harmful substances entering from outside the house.
[0007]
In recent years, due to the deterioration of urban environment, air contains various air pollutants (hazardous substances) such as sulfur dioxide, nitrogen oxides, carbon monoxide and suspended particulate matter. It is growing.
[0008]
Under these circumstances, opening a window and ventilating it, especially in an urban area, would result in harmful substances being drawn into the house, which is not preferable, but it is not possible to close the window.
In addition, in the case of ordinary houses, the air inside the house is replaced due to natural convection, so even if the windows are closed, air containing air pollutants (hazardous substances) etc. will gradually enter the house from outside. It will be pulled in.
As a result, the environment inside the house deteriorates, and there is a concern that the health of residents will be adversely affected.
[0009]
Therefore, in order to prevent deterioration of the environment inside the house and maintain and purify the environment inside the house, it is necessary to mainly remove air pollutants (hazardous substances) contained in air taken into the house from outside. It was started.
[0010]
[Means for Solving the Problems]
The present invention relates to an in-house environmental purification system made to solve such a problem. The environmental purification system in a house is provided with a preliminary air conditioning process, a preliminary processing space in which outside air is taken in, and the interior of the preliminary processing space. A processing unit for passing the pre-processed air through the processing unit filled with the air, an inlet for supplying the air after the pre-processing to the house interior space, and an outlet for discharging the air in the house interior space to the outside. are doing.
[0011]
In the in-house environmental purification system having such a configuration, the outside air guided into the house from the outside is taken into the pre-processing space where the pre-air conditioning has been performed. Then, after passing through the processing section provided in the preliminary processing space, the air is guided to the house space.
Since the processing section is filled with the porous adsorbent, harmful substances contained in the outside air are adsorbed by the porous adsorbent. As a result, the outside air from which the air pollutants (hazardous substances) have been removed is guided to the interior space of the house.
[0012]
At this time, the pre-treatment space is pre-air-conditioned, so even if there is a difference between the outside air and the air in the house space, the air from which the harmful substances have been removed after the temperature has been adjusted will remain in the house. It will be supplied to the space. Therefore, the temperature environment of the space in the house is not impaired. Then, the air in the space in the house is discharged outside through the discharge port due to a convection phenomenon.
[0013]
Note that, in the in-house environment purification system of the present invention, a forced circulation fan for forcibly taking in outside air into the pre-treatment space and forcibly supplying outside air taken into the pre-treatment space to the in-house space is provided. May be.
[0014]
By providing the forced circulation fan, the air that has passed through the processing unit is reliably supplied to the house space. Thus, the maintenance and purification of the environment in the house is performed more efficiently than in the case where natural convection is used.
[0015]
In addition, it is preferable that a temperature control pipe is buried in the foundation of the underfloor space which is the pretreatment space.
[0016]
When the temperature control pipe is buried in the foundation, it becomes possible to warm the foundation when hot water flows through the pipe. As a result, the air in the pretreatment space is warmed by the radiant heat from the foundation.
As a result, the convection of the air in the house is performed more efficiently.
[0017]
In addition, it is preferable that, in addition to the outside air, air conditioned by an air conditioner in a space in the house is taken into the pretreatment space.
[0018]
With such a configuration, part or all of the air in the house that has been air-conditioned by the air-conditioning equipment is taken into the pre-processing space. As a result, the air in the house is circulated again in the house after the purification process, and the environment in the house is maintained and purified.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic configuration diagram of a house provided with a house environment purification system according to the present invention.
[0020]
The present invention relates to a house environment purification system that achieves maintenance and purification of the house environment. More specifically, the present invention purifies the outside air by first taking in outside air into a pre-treatment space that has been subjected to a pre-air-conditioning treatment, and passing the outside air through a treatment section filled with a porous adsorbent. A house that performs treatment, supplies outside air after purification treatment to the house through the inlet, and discharges air in the house space outside through the outlet to maintain and purify the environment in the house. It is an internal environmental purification system.
[0021]
As shown in FIG. 1, in a house 1 provided with an in-house environment purification system according to the present invention, a first floor underfloor space 2 is used as a preliminary processing space.
Due to the natural convection of the air in the house 1, the outdoor air flows into the underfloor space 2 through an air inlet 5 that connects the underfloor space 2 provided at an appropriate position on the foundation 3 to the outside of the house. (Outside air) is led.
[0022]
A heat insulating material 4 is installed around the foundation 3 of the underfloor space 2 for preliminary air conditioning of the underfloor space 2. Therefore, the temperature in the underfloor space 2 is less likely to be affected by a temperature change in an external (outdoor) environment, and is kept relatively constant. With such a configuration, the temperature difference between the air in the house space 6 and the air in the underfloor space 2 becomes small, and when the pre-processed air is supplied to the house space 6, the house space 6, a rapid change in temperature is unlikely to occur.
[0023]
In addition, in this underfloor space 2, it is also possible to install air conditioning equipment such as a cooling and heating device and a dehumidifier in addition to the above-mentioned heat insulating material 4. These are also provided for preliminary air-conditioning processing, and it is possible to more accurately match the temperature and humidity in the underfloor space 2 with the temperature and humidity in the house space 6. As a result, not only can it be possible to prevent a rapid change in the temperature and humidity of the house interior space 6, but also it is possible to reduce the load on the air conditioning equipment provided in the house 1.
[0024]
A processing unit 9 filled with a porous adsorbent 8 is provided below the floor plate 7 that partitions the underfloor space 2 and the in-house space 6. There is provided a slit 10 that communicates with the house space 6.
[0025]
Thereby, the air that moves from the underfloor space 2 to the house space 6 due to the natural convection phenomenon is guided to the house space 6 after passing through the processing unit 9 without fail.
[0026]
As shown in FIG. 2, the processing unit 9 is configured by a plurality of tares 11 made of a nonwoven fabric, and the tare 11 is filled with the porous adsorbent 8.
By connecting the tare 11 vertically and horizontally according to the area of the floor plate 7, the processing unit 9 can be provided so as to cover the entire lower surface of the floor plate 7.
[0027]
In the present embodiment, the tare 11 has a substantially rectangular shape, but its size and shape can be appropriately changed. Further, in order to increase the contact area with the air, a configuration in which a plurality of tares 11 are further suspended below the processing unit 9, and the processing unit 9 is vertically moved so that the air passes through the processing unit 9 a plurality of times. It is also possible to adopt a configuration in which a plurality are provided in directions.
[0028]
In the present embodiment, the air in the underfloor space 2 always passes through the processing unit 9 and reaches the interior of the house 6. Therefore, the size of the mesh of the nonwoven fabric is preferably a size that does not allow the porous adsorbent 8 to spill, and is as large as possible so that air can efficiently pass through the processing section 9.
[0029]
Further, the material constituting the tare 11 can be appropriately substituted as long as it is a material excellent in air permeability, durability and workability such as a nonwoven fabric.
[0030]
FIG. 3 is a view showing an example of the mounting example of the processing unit 9. In FIG. 3, the end of the tare 11 is fixed to the side surface of the floor joist with staples.
However, the mounting method is not limited to this mode, and the tare 11 may be directly fixed to the lower surface of the floor plate 7, or the processing unit 9 may be formed in a plate shape, and the processing unit 9 may be directly mounted on the lower surface of the floor plate. Etc. can also be selected.
[0031]
The porous adsorbent 8 is a porous material having a large specific surface area and excellent adsorption performance. As such, for example, bamboo charcoal, charcoal, activated carbon, zeolite, and the like can be used.
[0032]
In the present embodiment, the use of bamboo charcoal is recommended as the porous adsorbent 8, so that the bamboo charcoal will be described below.
[0033]
<Bamboo charcoal>
Bamboo charcoal has numerous holes inside. These holes are honeycomb (honeycomb) shaped tubes, all open to the outside. The diameter of the honeycomb-shaped tube varies in size, and specifically, ranges from one-hundredth of a millimeter to one-thousandth of a millimeter, and these exist in a mixed state.
[0034]
Therefore, bamboo charcoal has a specific surface area per gram of 300 m ² or more and an adsorption power of 50 to 60 g / m ² . As apparent from the fact that Bincho charcoal has a specific surface area of ² to 5 m ² and an adsorption power of ² to 5 g / m ² , the adsorption power of bamboo charcoal is very large.
[0035]
In addition, all the pores of bamboo charcoal are open to the outside world, so that not only air and water but also nutrients can be taken into the pores from outside, creating an environment inside the pores where microorganisms can easily grow. Have been. In fact, it is known that various fungi such as filamentous fungi in large pores, actinomycetes in small pores, and bacteria in finer pores segregate. ing.
[0036]
When the bamboo charcoal having such characteristics is used as the porous adsorbent 8, the following operations and effects can be obtained.
[0037]
(Humidity adjustment function)
Since bamboo charcoal has a honeycomb structure as described above, it absorbs moisture in the air into the honeycomb structure when the humidity is high such as during the rainy season, and conversely when the humidity is low such as winter. Releases absorbed moisture.
[0038]
Therefore, when bamboo charcoal is arranged in the underfloor space, bamboo charcoal exhibits excellent humidity control performance and can control the humidity under the floor, so that it is possible to prevent the formation of dew condensation and mold.
[0039]
As a result, in the case of a wooden house, durability can be increased and maintenance costs can be greatly reduced, and termites generated due to condensation and mold under the floor can be effectively prevented.
Furthermore, bamboo charcoal has no toxicity to the human body, can be supplied at a low cost, and has an effect that lasts semipermanently. Therefore, it is preferable to bamboo charcoal which has been conventionally used to prevent the occurrence of mold and termites.
[0040]
Bamboo charcoal was actually laid under the floor and the humidity change under the floor was actually measured. The humidity under the floor was about 5% lower in summer and about 10% lower in winter. Did not reach more than 95%. Furthermore, no mold was found under the floor.
[0041]
(Removal of harmful substances)
As described above, microorganisms are formed on the surface of the bamboo charcoal pores, and a microbial membrane is formed.Therefore, impurities contained in water and air passing through the outer periphery and inside the pores of bamboo charcoal impinge on this microbial membrane. Adsorbed and decomposed. Here, the impurities refer to, for example, organic substances causing odor, and harmful substances such as various harmful chemical substances and air pollutants.
[0042]
Therefore, the air from which the harmful substances have been removed is supplied into the house, and the environment in the house can be maintained and improved.
In particular, bamboo charcoal easily adsorbs ammonia-based gas (odorous component) and also adsorbs pet smell and tobacco smoke well. Therefore, when air in the house is supplied to the underfloor space 2, It is also possible to efficiently purify the air in the house.
[0043]
(durability)
Since the adsorption performance of bamboo charcoal is chemical adsorption by microorganisms that grow on the pores, the adsorption performance is not affected over time. On the other hand, the adsorption performance of activated carbon is due to physical adsorption due to the size of its surface area, and the adsorption performance is lost over time, so an activation treatment is required as appropriate.
[0044]
Accordingly, bamboo charcoal is inferior to activated carbon in terms of adsorption power (in the case of activated carbon, 800 m ² or more per gram), but does not require an activation treatment unlike activated carbon, and thus can be used semipermanently.
[0045]
(Prevention of electromagnetic waves)
Since bamboo charcoal is almost entirely composed of carbon, it is excellent in conductivity and power storage. Therefore, it absorbs electromagnetic waves in the same manner as the principle of preventing lightning with a lightning rod. Therefore, it is possible to reduce the influence on the human body due to electromagnetic waves in a house, which has recently become a problem.
[0046]
(Cost performance)
Also, since bamboo charcoal has a large surface area, it consumes only half the amount of charcoal used (50 kg per tsubo is a guide) and is economical.
[0047]
(Other effects)
In addition to the characteristics of bamboo charcoal, it is known that bamboo charcoal has a mineral replenishing function such as silicate and potassium, a far-infrared ray effect, a healing effect, and the like.
[0048]
Since bamboo charcoal has the functions and effects described above, it is preferable to use it as the porous adsorbent 8 in the present invention.
The bamboo charcoal used in the present invention is not particularly limited as long as it is generally called bamboo charcoal. Therefore, the carbonization temperature is not particularly limited, and any one can be selected. Bamboo charcoal carbonized at 800 degrees is suitable as the bamboo charcoal used in the processing unit 9.
[0049]
<Charcoal>
Since charcoal also has the same performance as bamboo charcoal, it can be used as a porous adsorbent.
As wood suitably used for the production of charcoal, various woods used as a raw material of charcoal can be used, from broadleaf trees such as ubamegashi, oak, oak, oak, chestnut, and conifers such as larch, cedar, and hinoki. is there.
Various conventionally known methods can also be applied to the carbonization method, and the degree of progress of carbonization is also low-temperature carbonized charcoal obtained by carbonizing at 400 to 500 degrees, medium-temperature carbonized charcoal obtained by carbonizing at 600 to 700 degrees, Arbitrary materials such as high-temperature carbonized charcoal obtained by carbonizing at about 1000 degrees can be used.
[0050]
<Activated carbon>
Activated carbon also has the same performance as bamboo charcoal and can be used as a porous adsorbent. Activated carbon is a carbon having micropores formed by reacting a carbon or a carbon material such as coconut as a raw material with a gas or a chemical at a high temperature.
For example, in the case of powdered activated carbon, sawdust, hard wood chips, charcoal (ash), peat (peat), etc., and in the case of granular activated carbon, charcoal, coconut coal, coal (lignite, lignite, bituminous coal, anthracite, etc.) In the case of fibrous activated carbon, it can be made of rayon, acrylonitrile, coal pitch, petroleum pitch, phenol resin and the like.
[0051]
Hereinafter, a series of air flows in the indoor environment purification system according to the present invention will be described with reference to the drawings.
[0052]
First, the outside air guided into the underfloor space 2 through the intake port 5 of the foundation 3 rises due to the natural convection in the house 1 and moves toward the slit 10 in the underfloor space 2. The processing unit 9 is provided on the entire lower surface of the floor plate 7, and the raised air cannot reach the slit 10 without passing through the processing unit 9. Therefore, air enters the processing unit 9.
[0053]
Since the processing unit 9 is filled with the bamboo charcoal 8, the air that has entered the processing unit 9 passes through the outer periphery of the bamboo charcoal 8 and the inside of the honeycomb structure pipe of the bamboo charcoal 8.
At this time, due to the effect of the bamboo charcoal described above, the air is subjected to adsorption removal of impurities and the like in the air and other suitable treatments.
Then, the air from which impurities and the like have been adsorbed and removed is supplied from the processing section 9 to the house interior space 6 via the slit 10. Then, the air supplied to the in-house space 6 continues to rise, and is discharged to the outside through an outlet communicating the in-house space 6 with the outside.
[0054]
With this discharge, a minute negative pressure is generated in the house 1, and outside air is guided into the underfloor space 2 from the intake port 5 of the foundation 3. The ventilation in the house 1 is performed by this series of air circulation.
[0055]
[Second aspect]
Next, another embodiment of the in-house environment purification system according to the present invention will be described. FIG. 4 is a schematic explanatory diagram of a second embodiment of the in-house environment purification system according to the present invention.
[0056]
In the following description, the same components as those in the above-described first embodiment are denoted by the same reference numerals, and description thereof is omitted here.
[0057]
As shown in FIG. 4, in the in-home environment purification system of this embodiment, a fan F is provided in the underfloor space 2.
By providing the fan F, the outdoor air is forcibly supplied into the underfloor space 2 and the air in the underfloor space 2 is forcibly supplied from the underfloor space 2 to the house space 6.
This allows the air in the house 1 to be replaced in a shorter time than in the case of using the above-described natural convection phenomenon, so that the environment in the house can be more effectively purified.
[0058]
The position where the fan F is provided is not limited to the underfloor space 2. For example, the fan F is provided in the attic space 12 of the house, and the air in the house 1 is forcibly discharged to the outside. It is also possible to adopt a configuration provided in both the attic space 12.
[0059]
[Third aspect]
Next, another embodiment of the in-house environment purification system according to the present invention will be described.
FIG. 5 is a schematic explanatory diagram of a third embodiment of the in-house environment purification system according to the present invention.
[0060]
In the following description, the same components as those in the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted.
[0061]
As shown in FIG. 5, in the residential environment purification system of this embodiment, a temperature control pipe 13 is embedded in the foundation 3.
The temperature control pipe 13 is configured to allow hot water or cooling water to flow therein, so that the inside of the underfloor space 2 can be appropriately adjusted to a desired temperature.
[0062]
For example, when hot water flows in the temperature control pipe 13, the air in the underfloor space 2 is warmed and the bamboo charcoal 8 filled in the processing unit 9 is activated. Removal of harmful chemical substances and the like will be performed more effectively.
At this time, since the bamboo charcoal has a fast-heating property and a far-infrared function, the inside of the underfloor space 2 is more effectively warmed.
[0063]
Here, as shown in the figure, it is also possible to adopt a configuration in which the processing unit 9 is directly arranged on the foundation 3. When hot water flows through the temperature control pipe 13 in this state, the processing unit 9 is more effectively warmed in combination with the radiant heat of the foundation 3, so that the bamboo charcoal 8 is more activated, and the above-described operation and effect of the bamboo charcoal are more effective. Will be demonstrated.
[0064]
[Fourth aspect]
Next, another embodiment of the in-house environment purification system according to the present invention will be described.
FIG. 6 is a schematic explanatory view of a fourth embodiment of the in-house environment purification system according to the present invention.
[0065]
In the following description, the same components as those in the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted.
[0066]
As shown in FIG. 6, in the fourth embodiment of the present invention, in addition to outside air, air conditioned by an air conditioner 14 provided in the house 1 is taken into the underfloor space 2 which is a pretreatment space. .
Here, the air conditioning equipment 14 in the house space 6 is a device that takes in the air in the house space 6 and sends a part or all of the air after air conditioning such as heat exchange to the underfloor space 2 again.
[0067]
With such a configuration, the temperature of the air in the underfloor space 2 can be easily adjusted.
Further, the air in the in-house space 6 is supplied into the underfloor space 2, and the air processed by the processing unit 9 circulates again in the in-house space 6. As a result, the air in the house 1 can be purified.
In the present embodiment, the air is supplied from the air conditioner 14 to the underfloor space 2 through the outside of the house 1. However, the air after the air supply is supplied from the air conditioner 14 to the underfloor space 2. There is no particular limitation as long as the configuration is possible. For example, it is also possible to form an air guideway between the outer wall and the inner wall of the house and supply the air to the underfloor space 2 via the guideway.
[0068]
Although the preferred embodiment of the in-house environment purification system according to the present invention has been described above, the present invention is not limited to this. For example, as shown in FIG. 7, application to a house 1 'having a vertical hole 15 is also possible. In this case, it is also possible to adopt a configuration in which a processing unit is provided in each of the air intakes of each living room 16 of the house 1 '.
Further, the pre-processing space is not limited to the underfloor space, and it is possible to use the attic space 12 or a space separately provided outside the house.
[0069]
【The invention's effect】
In the in-house environmental purification system according to the present invention, the outside air guided from outside to the house is taken into the pre-processing space where the pre-air conditioning is performed, and the processing unit provided in the pre-processing space is provided. After passing, you will be led to the space inside the house. This processing unit is filled with a porous adsorbent, and harmful substances and the like contained in the outside air are adsorbed by the porous adsorbent, so that the outside air after removing air pollutants (harmful substances) is removed. , Led to the space inside the house.
[0070]
At this time, the pre-treatment space is pre-air-conditioned, so even if there is a difference between the outside air and the air in the house space, the air from which the harmful substances have been removed after the temperature has been adjusted will remain in the house. Supplied to the space. Therefore, purified air is supplied into the house without impairing the temperature environment of the house space.
[0071]
In particular, when a temperature control pipe is buried in the foundation of the pretreatment space, the foundation of the house is warmed by the hot water flowing in the pipe. As a result, the air in the pretreatment space is heated by the radiant heat from the foundation, and the convection of the air in the house is performed more efficiently.
[0072]
In addition, since the in-house environment purification system of the present invention is provided with a forced circulation fan that forcibly takes in outside air into the pre-treatment space and forcibly supplies air in the underfloor space to the house space, The air from which impurities and air pollutants (hazardous substances) have been removed is surely supplied to the interior space of the house. Thus, the maintenance and purification of the environment in the house is performed more efficiently than in the case where natural convection is used.
[0073]
Further, since the air after air conditioning from the air conditioning equipment in the house space 6 is taken into the pre-treatment space in addition to the outside air, a part or all of the air in the house is purified in the pre-treatment space. Later, it is circulated again to the house space 6. As a result, maintenance and purification of the environment in the house is achieved.
