Air Con

[Guest funkmiester]

has anyone had what looks like dry ice coming from the vents of their gal.

 

Thought it was smoke at first, kaked me pants, then realised it was evaporating a couple of inches from the vent.

 

Thing is, it aint that cold. think it might need regassing so I dont know what this might be ?

 

Any ideas

This happened to me the other day on a flight to Dublin. As the plane took off and climbed, at about 1,500 feet the cabin vents started to blow what looks like smoke at first glance. There was more than a little discussion in the cabin... After two minutes it disappeared.

 

It's just wet air, basically, caused by the chilled air picking up moisture from the ducting in the car. It should disappear fairly quickly as the dry air-conditioned air removes the moisture.

 

It could be that condensation has built up, possibly you have a wet cabin filter or another source of water (leak) in the system. It can just be a very warm and humid day and the car parked in the shade before you start it up.

 

(Where's Nik - he's a physics teacher, and can explain this better than I can... :ph34r: )

When air is warm it can carry more moisture than when it's cold (one of the driest areas of the globe is the polar areas). When chilled air enters the cabin and the air in the cabin has very high humidity the air has to give up the moisture because it can no longer carry it so a cloud is formed inside your gal. I have seen it many times on mine, nothing to worry about.

Thanks guys, was a bit worried there !! :lol:

I was worried too, the only way you would get dry ice coming out the vents is if you crashed into a CO2 tanker.....

Thanks JB. Perfect answer - who need Nik??!!.

 

Personally I've only seen this when there was another source of moisture. On the 'plane this is caused by condensation on the inside of the air pack ducts. OP could check for wet cabin filter, blocked scuttle drains?
