The air conditioner heats or cools the vehicle to maintain a predetermined temperature inside the vehicle. The load that determines the capacity of the air conditioner consists of heat transfer, solar radiation, equipment, human body, and ventilation load. When ventilation is performed as described above, the load of this ventilation amount is extremely large. For example, the ventilation load caused by the above ventilation accounts for about 57% of the total air conditioning load.

No. 3 has the property of selectively permeating carbon dioxide gas. The outlet side of the blower 51 is connected to the upstream side of the container 45 of the membrane separation device 41, and the duct 55 and the decompression pump 57 connected to the inside of the vehicle are connected to the downstream side. The container 45 is a plurality of separation membranes 4.
It is divided into multiple parts by 3. The outlet side of the blower 51 and the duct 55 are connected to the flow path on one surface of the separation membrane 43. A decompression pump 47 is connected to the flow path on the other surface of the separation membrane 43. The outlet of the filter 53, the inlet of the duct 55, the inlet of the decompression pump 57 and the flow passages on each surface of the plurality of separation membranes 43 are connected by a header.

The carbon dioxide gas is discharged to the atmosphere from the decompression pump 57 after entering the membrane separation device 41 via 3. The air from which carbon dioxide has been removed is returned to the inside of the vehicle via the duct 55.

なる。In order to selectively separate carbon dioxide gas, it is necessary to provide a pressure difference before and after the separation membrane 43. Blower 51
The pressure reduction pump 57 reduces the pressure of the downstream side of the separation membrane 43 to about 0.2 atm, thereby providing a pressure difference of about 0.8 atm with the upstream side of the separation membrane 43. Thus, only the high-concentration carbon dioxide gas selectively separated in the process of passing through the separation membrane 43 can be released to the outside of the vehicle, and the carbon dioxide concentration in the vehicle can be suppressed within a predetermined range.

大静圧を７ｋＰａ程度にしている。The ventilation air volume of the ventilation device 20 is about 20% of that of the conventional ventilation device and is 6 m 3 / min. Ventilation device 2
The maximum static pressure of 0 is set to about 7 kPa so that passengers do not feel uncomfortable when the passengers pass each other in the tunnel due to fluctuations in the pressure inside the vehicle.
【００２０】以下に、容積を１８０ｍ3 の車両の客室

を概算する。喫煙率を０％と仮定する。Below, the transition of the carbon dioxide gas concentration inside the vehicle when 100 passengers are seated in a passenger compartment of a vehicle having a volume of 180 m 3 will be roughly estimated. The smoking rate is assumed to be 0%.

い。一般に、酸素欠乏は酸素濃度が１８％以下と規定さ
れているため、６ｍ3／minの換気量があれば、酸素濃度
は問題ないと判断できる。When the ventilation volume is 6 m 3 / min, the oxygen concentration in the vehicle is saturated at about 20.5%. This is only about 0.4% lower than the atmospheric oxygen concentration of 20.9%. In general, oxygen deficiency is regulated to have an oxygen concentration of 18% or less. Therefore, if the ventilation volume is 6 m 3 / min, it can be determined that the oxygen concentration is not a problem.

圧ポンプ５７を用いて排出しているので、トンネルを高
速で走行する際の圧力変動に対応できる。Next, the carbon dioxide concentration will be examined. If the ventilation rate is 6 m 3 / min, the carbon dioxide concentration inside the vehicle is about 0.
After reaching 65%, it saturates. The concentration of carbon dioxide in the atmosphere is about 0.04%, which is about 16 times the concentration. However, the level has no effect on health. Since the pressure is reduced by using the decompression pump 57, it is possible to deal with the pressure fluctuation when traveling at high speed in the tunnel.
【００２３】文献によれば、車内を快適に維持するため
の炭酸ガス濃度は、０.１５〜０.２％に維持すべきと言
われている。According to the literature, it is said that the concentration of carbon dioxide gas for keeping the inside of the vehicle comfortable should be maintained at 0.15 to 0.2%.
【００２４】換気量を６ｍ3／minとした場合、約１４ｍ

酸ガス濃度を約０.１９％ 前後に維持できる。When the ventilation volume is 6 m 3 / min, about 14 m
The air in the car at 3 / min is supplied to the membrane separation device 41, and 0.0
If carbon dioxide of 28 m 3 / min is discharged to the outside of the vehicle, the carbon dioxide concentration inside the vehicle can be maintained at around 0.19%.

バランスが崩れる恐れは少ない。したがって、車内が負
圧になることもなく、ドアの開閉等の問題もない。Since high-concentration carbon dioxide gas is only discharged to the outside of the vehicle at 0.028 m 3 / min, there is little possibility that the balance between the amount of air supplied to the vehicle and the amount of exhaust will be lost. Therefore, there is no negative pressure inside the vehicle, and there is no problem of opening or closing the door.
【００２６】以上のように、換気量を６ｍ3／minに低減

炭酸ガス濃度を約０.１９％に維持することができる。
したがって、換気量の低減に伴い、空調負荷を低減でき

置全体を小型，軽量にできる。As described above, even when the ventilation amount is reduced to 6 m 3 / min, the carbon dioxide concentration in the vehicle can be maintained at about 0.19% by the carbon dioxide separation device 40.
Therefore, since the air conditioning load can be reduced as the ventilation volume decreases, it is possible to reduce the air conditioning load by about 40% as compared with the capacity of the conventional air conditioning system (corresponding to ventilation volume of 30 m 3 / min). Further, the entire device including the ventilation device 20, the air conditioner 30, and the carbon dioxide gas separating device 40 can be made small and lightweight.
