Description

  The present invention relates to an air conditioning system for a vehicle that prevents entry of harmful gas and harmful fine particles into the interior of a vehicle as much as possible.

  Conventionally, when traveling on urban or main roads or behind a diesel engine vehicle such as a truck, the air is polluted, so it is a problem from the viewpoint of passenger health to introduce outside air into the passenger compartment as it is was there.

Therefore, various filters for removing pollutants such as toxic gas and dust in the atmosphere have been developed. And the filter was attached to the outside air inlet for introducing outside air into the vehicle interior side, and air was introduced into the vehicle interior side through the filter using a blower. In this way, there has been a technique for filtering the air introduced into the vehicle interior side using a filter and a blower, and introducing clean air from which contaminants such as toxic gas and dust are removed into the vehicle interior side (for example, , See Patent Document 1).
JP-A-6-193525

  However, in the method of introducing the atmosphere into the vehicle interior side using the blower and the filter as described above, since a large amount of outside air is introduced into the vehicle interior side, electric power reaching several hundred watts may be required. That is, the load on the in-vehicle battery is large.

  This invention is made | formed in view of such a problem, and it aims at providing the vehicle air conditioning system which can reduce the load with respect to a vehicle-mounted battery.

  The vehicle air conditioning system according to claim 1, which has been made to solve such a problem, is formed between a floor plate on the vehicle interior side and an outer plate on the outside of the vehicle interior in a floor portion of the vehicle interior of the vehicle. The selective separation material is arranged in the space.

The floor plate forming the space is provided with an inside air intake for taking in the inside air from the vehicle interior side into the space and an inside air discharge port for discharging the inside air taken into the space into the vehicle interior side.
In addition, the outer plate forming the space is provided with an outside air inlet for taking outside air into the space from the outside of the vehicle compartment and an outside air outlet for discharging the outside air taken into the space to the outside of the vehicle compartment.

  Further, a selective separation material having a function of permeating oxygen and carbon dioxide from a higher concentration to a lower concentration and blocking hydrocarbons, nitrogen oxides, sulfur oxides and minute solid components is provided on the vehicle interior side and vehicle interior. It arrange | positions in space so that the outer side may be separated.

  According to the vehicle air-conditioning system configured as described above, the oxygen consumed by the occupant in the passenger compartment is taken in the passenger compartment by the selective separation material and the exhausted carbon dioxide is removed from the vehicle without introducing outside air into the passenger compartment by a blower or the like. It can be discharged outside. Hereinafter, this effect will be described in detail.

Outside air is taken in from the outside air inlet and discharged from the outside air outlet, and inside air is taken in from the inside air inlet and discharged from the inside air outlet.
Therefore, the outer surface of the selective separation material comes into contact with the outside air containing oxygen and carbon dioxide at a constant concentration. On the other hand, the air inside the passenger compartment has a higher carbon dioxide concentration and a lower oxygen concentration due to the breathing of the passengers. The selective separation material allows carbon dioxide and oxygen to permeate from the higher concentration to the lower concentration.

  Therefore, when the oxygen concentration on the vehicle interior side is lower than the oxygen concentration in the outside air, oxygen is supplied from the outside of the vehicle interior to the vehicle interior side where the concentration is reduced via the selective separation material. Further, if the carbon dioxide concentration is higher than the outside air concentration, carbon dioxide is discharged from the vehicle interior side where the concentration has increased to the vehicle interior outside through the selective separation material.

  In particular, while the vehicle is running, the amount of outside air taken in from the outside air intake increases, so that the outside air continues to hit the outer surface of the selected separation member while the vehicle is running. That is, outside air having a constant concentration of oxygen, carbon dioxide, sulfur oxide, and minute solid components continues to be supplied to the outer surface of the selective separation material.

  Therefore, when the vehicle is running, oxygen consumed by the occupant can be taken in by the selective separation material and the discharged carbon dioxide can be discharged outside the vehicle cabin without introducing outside air into the vehicle cabin side with a blower or the like. And since it is not necessary to operate a blower, the load with respect to a vehicle-mounted battery can be reduced.

In time and, selective separation material is not always necessary to arrange the floor entirely. In other words, the area required for the selective separation material is determined by the permeation performance of oxygen and carbon dioxide, the number of passengers inside the vehicle interior, the supply amount of outside air and inside air to the selective separation material, and the like.

Therefore, as described in claim 2 , even if the selective separation material is disposed in the under-seat portion of the vehicle, sufficient oxygen or carbon dioxide may be ensured.
Furthermore, when the selective separating member is disposed in the lower part of the seat, the occupant does not step on and the weight of the occupant is not applied to the selective separating member, so that the degree of reinforcement of the selective separating member can be reduced.

In this case, it is further preferable if only the front row seats of the driver's seat and the passenger seat can be installed as seats.
By the way, in consideration of the case where the vehicle travels, it is desirable that the outside air intake is in front of the vehicle. Further, when the outside air taken in from the outside air intake port is in contact with the surface of the selective separation material for a long time, oxygen and carbon dioxide exchanged between the vehicle interior side and the vehicle interior outside through the selective separation material increases. So desirable.

Therefore, as described in claim 3 , the outside air intake port may be disposed in front of the driver seat with respect to the vehicle traveling direction, and the outside air discharge port may be disposed behind the driver seat with respect to the vehicle traveling direction.
If it does in this way, the external air introduction path | route until the external air taken in from the external air intake port will be discharged | emitted from an external air discharge port will become long. That is, the outside air contacts the selective separation material for a long time. Accordingly, the amount of oxygen and carbon dioxide that can be exchanged between the vehicle interior side and the vehicle interior side increases.

Further, similarly to the arrangement of the outside air inlet and the outside air outlet described above, as described in claim 4 , the inside air inlet is arranged in front of the driver's seat with respect to the vehicle traveling direction, and the inside air outlet is disposed in the vehicle. You may arrange | position behind a driver's seat with respect to the advancing direction.

  If it does in this way, the inside air circulation path | route until the inside air taken in from the inside air intake port is discharged | emitted from an inside air discharge port becomes long. That is, the inside air comes into contact with the selective separation material for a long time. Accordingly, the amount of oxygen and carbon dioxide that can be exchanged between the vehicle interior side and the vehicle interior side increases.

By the way, when exchanging oxygen and carbon dioxide between the vehicle interior side and the vehicle interior side, it is better that the surface area of the selective separation material is large. However, the location of the selective separating material is narrow.
Therefore, as described in claim 5 , when the selective separation material is formed in a flat plate shape, and the selective separation material formed in the flat plate shape is folded in a bellows shape, the surface area of the selective separation material increases. The amount of oxygen and carbon dioxide that can be exchanged between the room interior and the vehicle exterior increases. Therefore, even if the concentration of oxygen or carbon dioxide on the vehicle interior side changes, the concentration of oxygen or carbon dioxide on the vehicle interior side can be restored to a predetermined value in a short time.

In addition, as described in claim 6 , the ridge line of the selective separating material folded in a bellows shape is a flow of outside air that is taken in from the outside air inlet and discharged from the outside air outlet, or is taken in from the inside air inlet. It is good to arrange | position so that it may correspond with the direction of the flow of the inside air discharged | emitted from a discharge port.

  In this way, the flow of the outside air flowing from the outside air intake port to the outside air discharge port or the flow of the inside air flowing from the inside air intake port to the inside air discharge port flows smoothly without being obstructed by the bellows portion. Accordingly, oxygen and carbon dioxide can be efficiently exchanged between the outside air and the inside air in the selective separation material.

Further, as described in claim 7 , the selective separation material is formed in a cylindrical shape. And it is good to comprise a selection member so that the external air taken in from the external air intake may be introduce | transduced into the inner surface of the selective separation material formed in the cylinder shape, and the internal air taken in from the internal air intake may be introduced into the outer surface.

  Alternatively, the selective separation material may be configured such that the outside air taken in from the outside air intake is introduced into the outer surface of the selective separation material, and the inside air taken in from the inside air intake is introduced into the inner surface.

In this way, the outside air and the inside air can be separated with a simple structure, and the selective separation material can reliably exchange oxygen and carbon dioxide between the outside air and the inside air.
Further, as described in claim 8 , the selective separation material is formed in a film shape, and the selective separation material formed in the film shape is formed in two. Furthermore, it forms in the spiral shape which wound the ridge part of the selective separation material folded in half inside. And you may comprise so that external air may be introduce | transduced into the inner space formed by folding the selective separation material into two, and internal air may be introduced into the outer space.

Alternatively, the inside air may be introduced into the inner space formed by folding the selective separation member in half, and the outside air may be introduced into the outer space.
Even if comprised in this way, since the surface area of a selective separation material can be enlarged, the exchange of oxygen and carbon dioxide between outside air and inside air can be performed efficiently.

Further, as described in claim 9 , the selective separation material is formed in a hollow fiber shape, and outside air is introduced into the hollow fiber, and inside air is introduced into the outside of the hollow fiber, or inside the hollow fiber. The inside air may be introduced, and the outside air may be introduced outside the hollow fiber.

  If comprised in this way, many selective separation materials can be filled into a narrow part. Moreover, since it is formed in a hollow fiber shape, the surface area is also large. Therefore, since the surface area of the selective separation material is increased, it is possible to efficiently exchange oxygen and carbon dioxide between the outside air and the inside air.

By the way, it is considered that the performance required for the selective separation material varies depending on the installation location. Therefore, as described in claim 10 , the selective separation material may have a porous shape, a fiber shape, a thin film shape, or a composite shape thereof.

  In this case, for example, in the case where the selective separation material is installed in a place where the installation area of the selective separation material is limited, the permeation of oxygen and carbon dioxide per unit area can be achieved by forming the selective separation material into a thin film shape. Since the performance can be improved, the installation area can be suppressed.

  Moreover, even if it is made into fiber shape like an air filter, since the surface area of a selective separation material becomes large, permeation | transmission performance can be improved. Furthermore, when the ambient temperature of the vehicle air conditioning system is high, a porous shape is advantageous because heat resistance increases.

Further, as described in claim 11 , the function of blocking the hydrocarbons, nitrogen oxides, sulfur oxides and minute solid components of the selective separation material is expressed by adsorption, absorption, decomposition or surface reaction. Good.

In the adsorption, the adsorption performance of the selective separation material can be regenerated by physically holding hydrocarbons and the like and then releasing the retained components to the atmosphere again by heating or the like when the vehicle is stopped.
Further, in absorption, hydrocarbons and the like can be mainly chemically fixed with a selective separation material and blocked.

Further, in the decomposition, the adsorbed and absorbed hydrocarbons, nitrogen oxides, and sulfur oxides can be chemically decomposed to make them non-brominated or harmless.
The surface reaction can be blocked by making it difficult to selectively adsorb hydrocarbons or the like due to the structural characteristics of the surface of the selective separation material and preventing entry into the membrane.

  Here, as a means for decomposing, for example, a method of electrically decomposing, a method of decomposing thermally, a method of decomposing chemically using chemicals, a method of decomposing biologically using microorganisms, etc. Conceivable. Furthermore, a method of improving the ability by combining these methods is also conceivable.

Further, the function of blocking the solid minute component may be expressed by filtering as described in claim 12 .
By the way, the selective separation material may be exposed to a relatively high temperature when the vehicle is exposed to hot weather. Therefore, as described in claim 13, it is preferable that the selective separation material can be cooled.

  In other words, a temperature sensor for measuring the surface temperature of the selected separation material and an outside air introduction path from the outside air inlet to the outside air outlet or an inside air circulation path from the inside air inlet to the inside air outlet, the temperature sensor And a cooling means for cooling the selective separation material when the surface temperature of the selective separation material measured in (1) reaches a predetermined temperature.

If it does in this way, when the surface temperature of a selective separation material turns into predetermined temperature, since a selective separation material can be cooled with a cooling means, the performance of a selective separation material can be maintained.
Here, the “predetermined temperature” refers to a temperature at which the permeation performance of oxygen and carbon dioxide of the selective separation material and the cutoff performance of hydrocarbons or the like are not more than the minimum values required.

  By the way, when outside air or inside air is brought into contact with the selective separation material, dust floating outside the vehicle interior adheres to the surfaces of the selective separation material on the vehicle interior side and the vehicle interior outside. Therefore, the permeation performance of oxygen and carbon dioxide of the selective separation material is lowered.

Therefore, as described in claim 14, it is preferable to vibrate the selective separation material to include a vibration means for removing dust adhering to the surface of the selective separation material.
In this way, it is possible to remove the dust attached to the interior and exterior surfaces of the selective separation material by sieving by vibration, so that the oxygen and carbon dioxide permeation performance of the selective separation material can be restored. Can do.

Furthermore, when the amount of dust adhering to the surface of the selective separation material increases, it is convenient that the selective separation material can be exchanged. Therefore, as described in claim 15, it is preferable that the selective separation material is accommodated in a cartridge configured to be detachable, and a portion where the selective separation material is disposed is detachably formed.

  If it does in this way, since exchange can be easily performed when a large amount of dust adheres to the surface of the selective separation material or the selective separation material becomes dirty, the exchange performance of oxygen and carbon dioxide can be quickly recovered. .

  By the way, when the permeation performance of the selective separation material is lowered and the oxygen concentration on the vehicle interior side is lowered or the carbon dioxide concentration is raised, or due to an unexpected situation, a human body such as another gas such as carbon monoxide It is conceivable that the concentration of gas that causes danger increases rapidly.

In order to cope with such a situation, as described in claim 16 , a gas concentration detecting means for detecting a gas concentration inside the passenger compartment and air outside the passenger compartment are introduced into the passenger compartment or inside the passenger compartment. Inside / outside air exchanging means capable of discharging air to the outside of the passenger compartment, and when the gas concentration detected by the gas concentration detecting means reaches a predetermined value, the air outside the passenger compartment is passed through the inside / outside air exchanging means to the inside of the compartment It is preferable to provide control means for introducing or discharging the air on the vehicle interior side to the vehicle exterior side.

  In this way, when the oxygen concentration on the vehicle interior side decreases or the carbon dioxide concentration increases, by introducing outside air into the vehicle interior side, the oxygen and carbon dioxide concentrations can be adjusted appropriately in a short time. Can be set to any value.

  In addition, if the concentration of a gas that causes danger to the human body suddenly increases due to unforeseen circumstances, the gas can be quickly discharged to the outside of the passenger compartment. Can be secured.

Embodiments to which the present invention is applied will be described below with reference to the drawings. The embodiment of the present invention is not limited to the following embodiment, and can take various forms as long as they belong to the technical scope of the present invention.

As shown in FIG. 1A, the vehicle 10 is surrounded by a wall 19 such as aluminum or glass that does not allow air to pass through, and a vehicle 19 such as a trunk or an engine room in which the outside air can enter and the outside air can not enter. It consists of a space outside the chamber 19.

Further, as shown in FIG. 1B, a space 51 is formed between the floor plate 52 and the outer plate 54 in the floor portion 50 of the passenger compartment 19.
The vehicle 10 is provided with an air conditioner (not shown). This air conditioner has only the inside air circulation mode.

(Vehicle air conditioning system structure)
Next, the configuration of the vehicle air conditioning system will be described. FIG. 1B is a schematic structural diagram schematically showing the structure of the floor portion 50.

As shown in FIG. 1B, the floor portion 50 includes a floor plate 52 facing the inside of the vehicle compartment 19 and an outer plate 54 facing the outside of the vehicle compartment 19.
A space 51 is formed between the floor plate 52 and the outer plate 54 by the floor plate 52, the outer plate 54, and the side plate 53, and the selective separating material 13 is disposed in the space 51.

  The floor plate 52 is provided with an inside air inlet 52 a for taking in the inside air from the inside of the vehicle compartment 19 into the space 51 and an inside air outlet 52 b for discharging the inside air taken into the space 51 into the inside of the vehicle compartment 19.

  The inside air intake port 52a is disposed in front of the driver's seat with respect to the traveling direction of the vehicle 10, specifically, below the driver's feet. Further, the inside air discharge port 52b is provided behind the driver's seat with respect to the traveling direction of the vehicle 10, specifically, immediately before the rear seat.

  In the outer plate 54, the outer plate 54 that forms the space 51 discharges the outside air intake 54 c for taking outside air from the outside of the vehicle compartment 19 into the space 51 and the outside air taken into the space 51. An outside air outlet 54d is provided.

  The outside air intake 54c is disposed in front of the driver's seat with respect to the traveling direction of the vehicle 10, specifically, below the driver's feet. The outside air outlet 54d is provided behind the driver's seat in the traveling direction of the vehicle 10, specifically, immediately before the rear seat.

  In the space 51, the selective separation member 13 is disposed so as to separate the inside of the vehicle compartment 19 from the outside of the vehicle compartment 19. Specifically, the selective separating material 13 is formed in a flat plate shape, and its end is closely fixed to the space 51 side surface of the side plate 53 forming the space 51 with an adhesive or a sealing material.

  In FIG. 1B, the selective separation material 13 is schematically shown in a flat plate shape, but is actually folded in a bellows shape as described in detail in the structure of the selective separation material 13 described later. It has a different shape.

Further, a temperature sensor 60 is provided on the surface of the selective separation member 13 outside the vehicle compartment 19, and two fans 56 a and 56 b are provided in the space 51.
The temperature sensor 60 is for measuring the surface temperature of the selective separation material 13, and converts the surface temperature of the selective separation material 13 such as a thermocouple, a platinum resistor, and a thermistor into an electrical signal and outputs it. .

The fans 56a and 56b are installed in an inside air circulation path from the inside air intake port 52a to the inside air discharge port 52b and an outside air introduction path from the outside air intake port 54c to the outside air discharge port 54d. Then, it operates when the surface temperature of the selective separation material 13 measured by the temperature sensor 60 reaches a predetermined temperature of the selective separation material 13 and selectively separates by taking in the outside air from the outside air inlet 54c and the inside air from the inside air inlet 52a. The material 13 is cooled (air cooled).

(Structure of selective separation material)
Next, the structure of the selective separation material 13 arranged in the space 51 will be described with reference to FIG. FIG. 2 is a structural diagram showing an outline of the selective separation material 13. FIG. 2A is a perspective view of the selective separating material 13 folded in a bellows shape, and FIG. 2B is a view of the selective separating material 13 folded in a bellows shape as viewed from the front side of the vehicle 10. .

  The selective separation material 13 has a thin film shape having a function of permeating oxygen and carbon dioxide from a higher concentration to a lower concentration and blocking hydrocarbons, nitrogen oxides, sulfur oxides and minute solid components. Yes.

  If the thickness of the selective separation material 13 is thin, it is advantageous for allowing gas to permeate. However, if the thickness of the selective separation material 13 is small, the strength of the membrane decreases and the film tends to break, so that there is a manufacturing limit. In this embodiment, the film thickness is 100 nanometers.

Further, the function of blocking the hydrocarbons, nitrogen oxides, sulfur oxides and fine solid components of the selective separation material 13 is expressed by adsorption, absorption, decomposition or surface reaction.
The selective separating material 13 is formed in a flat plate shape as described above. Further, the selective separating material 13 formed in the flat plate shape is bellows-shaped as shown in FIGS. 2 (a) and 2 (b). And is arranged in the space 51. Further, the ridge line 13a of the selective separating material 13 folded in a bellows shape is arranged so as to coincide with the direction in which the outside air and the inside air flow.

  The selective separating member 13 configured as described above is reinforced by a reinforcing member 40 as shown in FIG. FIG. 3 is a view showing a configuration of a reinforcing member 40 for reinforcing the selective separation member 13. 3A and 3B and the diagram shown on the left side in FIG. 3C show a state in which the selective separating member 13 in which the reinforcing member 40 is arranged is arranged on the floor 50 of the vehicle 10. FIG. 6 is a view of the vehicle 10 as viewed from above. 3C is a cross-sectional view of the selective separating material 13 in which the reinforcing member 40 is disposed.

  The reinforcing member 40 is used to reinforce the selective separating member 13 and is composed of members 40a, 40b, and 40c. The members 40a, 40b, and 40c are metal materials such as aluminum formed in a round bar shape.

  The member 40a is arrange | positioned so that a frame may be formed along 4 sides inside the compartment 19 of the selective separation material 13 formed in flat form, as shown to Fig.3 (a). Moreover, the member 40b is arrange | positioned on the diagonal of a frame in order to raise the intensity | strength of a frame.

  Furthermore, a member 40 c for reinforcing the frame is disposed along the short direction of the reinforcing member 40. In addition, in the point which each vertex of each frame and each member 40a, 40b, 40c cross | intersect, each member 40a, 40b, 40c is couple | bonded by welding, a rivet, or adhesion | attachment.

  Further, as shown in FIG. 3B, the reinforcing members 40 may be formed in a lattice shape. Specifically, the vertical members 40d and the horizontal members 40e are assembled in a lattice shape, and the points where the vertical members 40d and the horizontal members 40e intersect are joined by welding, rivets, adhesion, or the like.

  The members 40a, 40b, and 40c may be made of a material other than metal, for example, a resin material, as long as necessary strength can be ensured. A metal square may be used instead of the metal round bar.

Further, when it is necessary to further increase the strength, the reinforcing member 40 may be disposed not only on the inner side surface of the selective separation member 13 but also on the outer side surface of the passenger compartment 19.
Further, when it is not necessary to reinforce the planar portion of the selective separating member 13 with the reinforcing member 40, such as when the selective separating member 13 is disposed under the seat 90, as shown in FIG. The member 40f may be disposed on the side surface of the selective separation member 13.

(Characteristics of vehicle air conditioning system)
According to the vehicle air conditioning system as described above, outside air is taken in from the outside air inlet 54c and discharged from the outside air outlet 54d, and inside air is taken in from the inside air inlet 52a and discharged from the inside air outlet 52b.

  Therefore, the surface of the selective separation material 13 on the outer side of the passenger compartment 19 comes into contact with the outside air containing a certain concentration of oxygen or carbon dioxide. On the other hand, the air inside the passenger compartment 19 has a high carbon dioxide concentration and a low oxygen concentration due to the breathing of the occupant. Further, the selective separation material 13 transmits carbon dioxide and oxygen from the higher concentration to the lower concentration.

  In other words, when the oxygen concentration inside the vehicle compartment 19 becomes lower than the oxygen concentration in the outside air, oxygen is supplied from the outside of the vehicle compartment 19 to the inside of the vehicle compartment 19 where the concentration is low via the selective separation material 13. Further, if the carbon dioxide concentration becomes higher than the outside air concentration, carbon dioxide is discharged from the inside of the vehicle compartment 19 where the concentration has increased to the outside of the vehicle compartment 19 through the selective separation material 13.

  In particular, since the amount of outside air taken in from the outside air intake 54c increases while the vehicle 10 is traveling, the outside air continues to hit the surface of the selective separation member 13 on the outer side of the vehicle compartment 19 while the vehicle 10 is traveling. That is, outside air having a constant concentration of oxygen, carbon dioxide, sulfur oxide, and minute solid components is continuously supplied to the surface of the selective separation material 13 on the outer side of the passenger compartment 19.

  Therefore, when the vehicle 10 is running, oxygen selected by the occupant can be taken in by the selective separation member 13 and the discharged carbon dioxide can be discharged outside the passenger compartment without introducing outside air into the passenger compartment 19 with a blower or the like. it can. And since it is not necessary to operate a blower, the load with respect to a vehicle-mounted battery can be reduced.

Since at least the vehicle compartment 19 side of the selective separating member 13 is protected by the reinforcing member 40, even if an occupant or the like steps on the selective separating member 13, the selective separating member 13 is not damaged.
Further, since the reinforcing member 40 is disposed on at least two opposing side surfaces of the side surfaces of the selective separation material 13, the selective separation material 13 is unlikely to be damaged.

  The outside air inlet 52c is disposed in front of the driver's seat with respect to the traveling direction of the vehicle 10, and the outside air outlet 52d is disposed behind the driver's seat with respect to the traveling direction of the vehicle 10. Furthermore, the inside air inlet 52a is disposed in front of the driver's seat with respect to the traveling direction of the vehicle 10, and the inside air outlet 52b is disposed behind the driver's seat with respect to the traveling direction of the vehicle 10.

Therefore, there are an outside air introduction path until the outside air taken in from the outside air inlet 52c is discharged from the outside air outlet 52d and an inside air circulation path until the inside air taken in from the inside air inlet 52a is discharged from the inside air outlet 52b. become longer. That is, the outside air contacts the selective separation material 13 for a long time. Therefore, the amount of oxygen and carbon dioxide that can be exchanged between the inside of the vehicle compartment 19 and the outside of the vehicle compartment 19 increases.

  Further, the selective separation material 13 is formed in a flat plate shape, and the selective separation material 13 formed in the flat plate shape is folded in a bellows shape. Therefore, since the surface area of the selective separation material 13 increases, the amount of oxygen or carbon dioxide that can be exchanged between the inside of the vehicle compartment 19 and the outside of the vehicle compartment 19 increases. Therefore, even if the concentration of oxygen or carbon dioxide inside the passenger compartment 19 changes, the concentration of oxygen or carbon dioxide inside the passenger compartment 19 can be restored to a predetermined value in a short time.

  Further, the ridge line 13a of the selective separating member 13 folded in a bellows shape flows from the outside air intake port 52c and is discharged from the outside air discharge port 52d, and from the inside air intake port 52a and from the inside air discharge port 52b. It arrange | positions so that it may correspond with the direction of the flow of the inside air discharged | emitted.

  Therefore, the flow of the outside air flowing from the outside air intake port 52c to the outside air discharge port 52d and the flow of the inside air flowing from the inside air intake port 52a to the inside air discharge port 52b flow smoothly without being disturbed by the bellows portion. Therefore, the selective separation material 13 can efficiently exchange oxygen and carbon dioxide between the outside air and the inside air.

  Moreover, since the selective separation material 13 has a thin film shape, the permeation performance of oxygen and carbon dioxide per unit area can be improved. Therefore, the installation area can be suppressed.

Further, the function of blocking the hydrocarbons, nitrogen oxides, sulfur oxides and fine solid components of the selective separation material 13 is expressed by adsorption, absorption, decomposition or surface reaction.
In the adsorption, when the concentration of hydrocarbons or the like increases, the adsorption performance of the selective separation material 13 is regenerated by holding them mainly physically once and releasing them again to the outside air when the concentration decreases. can do.

Further, in absorption, hydrocarbons and the like can be mainly chemically fixed and blocked by the selective separation material 13.
Further, in the decomposition, the adsorbed and absorbed hydrocarbons, nitrogen oxides, and sulfur oxides can be chemically decomposed to make them non-brominated or harmless.

The surface reaction can be blocked by making it difficult for the hydrocarbons and the like to be selectively adsorbed by the structural characteristics of the surface of the selective separation material 13 and preventing entry into the membrane.
Here, as a means for decomposing, for example, a method of electrically decomposing, a method of decomposing thermally, a method of decomposing chemically using chemicals, a method of decomposing biologically using microorganisms, etc. Conceivable. Furthermore, a method of improving the ability by combining these methods is also conceivable.

  In addition, when the surface temperature of the selective separation material 13 measured by the temperature sensor 60 reaches a predetermined temperature, the selective separation material 13 is cooled by the fans 56a and 56b. it can.

Here, the “predetermined temperature” refers to a temperature at which the permeation performance of oxygen and carbon dioxide of the selective separation material 13 and the cutoff performance such as hydrocarbons are not more than the minimum values required.
[Second Embodiment]
Next, a method for rapidly recovering the oxygen concentration inside the passenger compartment 19 by introducing outside air when the oxygen concentration inside the passenger compartment 19 decreases will be described with reference to FIG.

  FIG. 4 is a diagram illustrating a method for controlling the oxygen concentration in the passenger compartment 19. FIG. 4A is a diagram showing an attached state of the oxygen sensor 18, and FIG. 4B is a graph showing a change in the oxygen concentration in the passenger compartment 19 measured by the oxygen sensor 18, and FIG. c) is a graph showing the opening degree of the inside / outside air damper 17.

  In the present air conditioning system, the selective separating material 13 having a function of preferentially permeating oxygen and carbon dioxide consumed by passengers inside the passenger compartment 19 and blocking hydrocarbons, nitrogen oxides, sulfur oxides and fine solid components; It has.

  However, if the permeation performance of the selective separation member 13 deteriorates for some reason, there is a possibility that it may not be possible to introduce an amount of oxygen that supplements the amount of oxygen consumed by the passenger inside the vehicle compartment 19. To prevent this, as shown in FIG. 4B, the oxygen concentration α inside the passenger compartment 19 is detected by the oxygen sensor 18 attached inside the passenger compartment 19 as shown in FIG. In the control unit, it is determined whether or not the detected oxygen concentration α is lower than the concentration threshold β (19.5% in FIG. 4B).
