air circulation in cars

[badkuk]

just wondering out loud...does the air inside the cabin get vented outside somehow? iniisip ko kasi, won't there be significant CO2 buildup within the cabin on long drives? and, well, kung medyo nagcollect na ng air sa loob...won't it be harder for the aircon/blower to pump in more air?

Yes, it gets vented out. Hindi naman 100% air-tight ang cabin ng mga automobiles.

Yan ang problema ng kotse ko ngayon. pag naka OFF yung circulation ( the air should circulate from outside)... pero ang nangyayari ay halos nawawala na yung FAN nya. Pero pag naka ON ay OK naman sya.

But I think kahit na ON ang circulation ay OK lang yan sa long drive.

Whether your air circulation is ON or on VENT, the car isn't airtight. Otherwise, you'd suffocate within an hour. :lol:

That's why you can still smell the stink of Manila bay at Blue Wave in Macapagal, even with the windows closed...

it is just like your window aircon at home, kahit walang vent or closed ang vent, it sucks in air from the outside. opening the vent simply closes the recirculate port and all the air comes from outside. with the vent closed there is still a small opening for outside air to come in. the cabin is not completely sealed so excess air can go out.

meron vent sa bandang likod ng mga cars. para hindi mabasag mga eardrums ng mga nakasakay sa loob whenever the doors are closed.

Yap sa likod that's true as a means to balance the atmospheric pressure especially on new cars with still very tight door seals, moreso this is also for air source kaya nga may filter din ito and for some auv's I know like Isuzu may blower fan pa para maganda circulation ng air sa loob. Yung vent sa dash kung meron nun, you need to open it once in a while during long drives to allow more fresh air to circulate inside then close it again para di hirap yung aircon to cool the air inside. Kung wala naman nun, make a small window opening pa-minsan minsan.

yeah, may vent sa trunk. i found this out when i put an andoks chicken in there. and within minutes, the entire cabin smelled of roast chicken!

now i put my car freshener in the trunk! this way the cabin is not overwhelmed by the scent when parked too long. mag circulate lang ung scent pag on ng AC.

is there a vent from the trunk goin to the outside? from inside of the car to the trunk its basicaly open conection.

Yes, there is a vent to the atmosphere via the trunk. It's those big plastic grilles on the sides when you take the rear bumper off.

On some vehicles like the Urvan Escapade, early L200, GEN I Pajero and a host of other models, the vent to the atmosphere is a styling element integrated onto the C or D-pillar.

kahit po air tight ang kotse, basta gumagana nang maayos ang air conditioning system, di magkakaroon ng CO2 build-up...

the air conditioning system traps significant amount of the carbon out of the CO2 (on the evaporator), then gives the fresh air again out of the louvers...

If you may have noticed, kahit na never kang nagbubukas ng bintana sa kotse, lakas pa rin ng dust sa loob which is actually because of the carbon out of the people's breath.... same dust that's being caught on the aircon's air filter and evaporator coil...

I hope this helps....
