Air Con. Maintenance -- 406 Hdi.

I believe it is held to be good practice to run the A/Con for 10/15 mins per
week to prevent "drying out" of joints. How can this be done during a UK
winter with ambient well below +14C, the minimum discharge temp. of the A/C
system?

Just a general query. If you have A/C why aren't you using it?
Or are you a troll?

 

I wish I knew the answer to that one, it's been bugging me since 'uprating'
to a climate ctrl version of the 406 aircon.
On the face of it, you can't get it to run in winter, or does it turn on the
compressor whenever the a/c light appears and it then tries to ctrl the temp
with the fans?

The aircon system in a car isn't there just to provide nice chilled
air on a hot day - it also has a dehumidifier. Try setting the temp at
whatever you feel comfortable with and the switch on the aircon. It
will quickly clear a misted windscreen. Do that every morning for 10
mins and want you want to do will be achieved.

When you use the screen only option on the climate control it switches on
the air con if used first thing in the morning.

Yep pollen filter as well, but how do you get the compressor on to oil
inside the refigerent pipes in winter if the climate ctrl doesn''t have a
setting lower than the ambient temp?

 

Are they not JUST refrigerant pipes - may be worth checking if just
running the AC does the job - I've never read anywhere that the AC HAS
to be on chill

Hej,

The discharge temp. is about 2 degrees C. If the outside temp. is below
freezing the A/C will turn off after a short while.
The temperature inside the cabin will be regulated (If automatic A/C) by
heating up the air with the heater matrix.

Same if manual A/C, but the system will turn off after a while if outside
tempeerature is below freezing.

Gents,

There seems to be some confusion, Peter understands how it works, what he is
saying is that the air conditioner's when switched on are always working.

They work by blowing the air over the chiller, this removes much of the
moisture from the air, if the air is then too cold it will re-direct the air
through the heater, giving you dry air at the desired temperature.

This is how the windows get demisted quickly.

Ah, so (Sounded a bit Japanese there) the compressor does run whenever the
a/c light is on then and we were worrying about nothing.
I have to say that does sound a rather fuel-inefficient way of acheiving an
end, cooling then heating the air again.
Up to now I've always managed to demist using the heater ... like in the
olden days ;-)

Had to snip the OP due to top posting.

 

We wont get into this argument again, but there's nothing wrong with top
posting...

If you have a manual a/c then the compressor is running as soon as you
turn the a/c on. This has nothing to do with outside temperature. Turn
on the a/c and select whatever temperature you want.

If you have one of these nice automatic ones you don't have to care
about it. It will automatically turn one once in a while. At least
that's what the manual of my Volkswagen Passat told me.

Turning on the heater does not demist your car. The only reason why your
windows get clear is that warm air is able to carry more water than cold
air. Using the a/c actually demists the interior since the moisty air in
the car is replaced by try air from the a/c.

When driving my 206 in winter I usually turn on the a/c for the first 5
or 10 minutes (heater set to "hot as hell"). This clears all the
windows. I then turn it off to save gas...

 

No but it does de-mist the windows ;-)

 

Yes there is.

 

No doubt here... But the moisture stays in the car. As soon as it cools
down you'll have the same problem again. So what you really want is to
get the moisture out of the car.

My thanks to all who contributed to clearing the fog and thoroughly
ventilated
this subject. I must say that I never imagined the design involved cooling
by
refrigerant(dehumidifying) followed by heating over the heater matrix. This
being
so,however,I can see advantage in leak prevention from running the automatic
aircon in winter. I will also, in order to maintain this Saharan climate
never open
a window or door for more than a split second.
May I wish you all Happy Motoring in 2005.
