Car Forum / Peugeot Cars / January 2005Air 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? TIA W@L. Just a general query. If you have A/C why aren't you using it? Or are you a troll? >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.

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

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.

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? >> >I believe it is held to be good practice to run the A/Con for 10/15 mins >per [quoted text clipped - 14 lines] >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 SignatureCheers Peter Remove the INVALID to reply 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. Andy >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.

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... :) Andy >> Gents, >> [quoted text clipped - 19 lines] > > Had to snip the OP due to top posting. > We wont get into this argument again, but there's nothing wrong with top > posting... :) [quoted text clipped - 24 lines] > > > > Had to snip the OP due to top posting. Yes there is. > 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. 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. > Up to now I've always managed to demist using the heater ... like in the > olden days ;-) 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... > 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.

No but it does de-mist the windows ;-) > No but it does de-mist the windows ;-) 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. Rgds, W@L. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ >> No but it does de-mist the windows ;-) > > No doubt here... But the moisture stays in the car.
