34laxy Posted February 1, 2007 Report Posted February 1, 2007 Anyone tried recharging the air con gas with the diy kits from Halfords? Thanks. Quote
Guest MATT jr Posted February 2, 2007 Report Posted February 2, 2007 yep - worked fine as a top up only -- wouldn't recommend it for a complete refill! MJR Quote

Guest MATT jr Posted February 2, 2007 Report Posted February 2, 2007 because their might be moisture and air in the system that should be removed before filling - with correctly weighed out gas. you cannot do any of this with the halfords kits, although im sure the system would "work" if you did it, i still think its wiser to get it correctly done, if the system is completely empty - or has had a new part fitted - and thus is empty. we've got one of the halfords kits, we took it Spain just incase, and we only use it to top up the system - if the AC doesnt seem as cold as it should be - weve also got a vent temperature thingy, but all of this can be affected by the ambient temperature - hence why it is again better to get it done properly - and have the gas weighed - rather than base it on system pressure.

Smilge Posted February 2, 2007 Report Posted February 2, 2007 How do you weigh gas? With an extremely light pair of weighing scales and a big net Maz :lol: Quote
Guest MATT jr Posted February 2, 2007 Report Posted February 2, 2007 newtons law Can you weigh the gas in a closed container? The answer from Newton's laws is yes! If you weigh an "empty" compressed gas cylinder and fill it with high pressure gas, it will then weigh more on an ordinary scale since you are weighing the gas in the cylinder. this is noticeable with calor gas bottles (used in caravans) - a full 7KG gas bottle - weighs considerably more than an empty gas bottle - and is noticeable with out scales (simply lifting it!)

NikpV Posted February 2, 2007 Report Posted February 2, 2007 How do you weigh gas? appears to be a typical misconception here - a cubic meter of air actually has a mass of about 1.3Kg (more than a bag of sugar - it doesn't feel like it because it is 'floating' in more air - odd but true :lol: :lol: :lol: Quote
Guest MATT jr Posted February 2, 2007 Report Posted February 2, 2007 like water! did you know...if you took a cylinder of air, the same height, width, and depth of the eiffel tower - the air will weigh more then the tower itself! MJR Quote

MJR funny - but I did know that :lol: :lol: :lol: :lol: :lol: Its a job related thing ...... Quote

34laxy Posted February 5, 2007 Author Report Posted February 5, 2007 Thanks for the advice MJR. A session for my Galaxy at the hands of the local AC engineer sounds the best bet. Hope the evaporator/condenser aren't blown... PS: Apologies for the quoted reply without the above text. Not sure what happend. Quote
