Re: Filling system up without vacumm
If you are currently working on a refrigeration system............STOP immediateley and get the services of a properly trained refrigeration engineer, your last couple of posts are scaring me.

Re: Filling system up without vacumm
it is not working i dont have the gas... only have 404 and not 407 only monday going to get some 407... i will make vaccum with an old compresor half hour then put the amount of gas sayed by the manufacture... 560grams... it is wath i am going to buy...
anyway wath should be the working presures?

Re: Filling system up without vacumm
depends on unit. can be somewhere in between -10 and 0 degrees celcius for 407c. just check suction line temp. must be few degrees above evaporating temp.

Re: Filling system up without vacumm
And they wonder why there is a big hole in the ozone layer with people like this "messing" with systems, if you do not know, leave it alone.

Re: Filling system up without vacumm
they are... ozone friendly, but they still do some global warming...
by the way you have tons of old refrigerators on the dumps beeing destroyed without takeing the gas out... this old refregirrators as you know use R12 ....

If you don't pressure test after repair how do you know the repair is OK, it may vaccum, but then leak when you add gas (should be added as refrigerant liquid). You would then be adding your refrigerant to the Ozone layer

Re: Filling system up without vacumm
the system is new... doesnt have any leaks....
how can i make a presure test ? azot ?

You will need a regulator and gauges/gauge lines
Better have an engineer pressure test and vacumn the system with a vacumn pump which will produce a better vacumn than a compressor

Re: Filling system up without vacumm
the system is new but it comes with no gas at all.
and the system doesn't have any info about presures... only kind of gas and quantity...
wath should be the presures ?
i have 2 compresores to do the vacumm how long should i make it ? and wath shoulb be the value ?

You may be able to boil off the moisture using a compressor, if it is very warm both at the indoor and the outdoor unit, I'll say it again MAY
You should ask your supplier for the operating pressure
the compressor will have a pressure max on it, but this maybe higher than the rest of the system can take

Re: Filling system up without vacumm
Get it commissioned properly by a qualified engineer. It must me pressure tested to the correct pressures, tool little you might not find any residual leaks, too much you might blow yourself up. It HAS to be ecacuated properly! and you cannot charge it to prearranged pressures, there are other factors involved.

You want to use the wrong refrigerant but think that that is OK. If your car or van runs on petrol go and put some diesel in the tank instead. If it runs on diesel fill it with petrol for a change. Then wonder why the local garage passes a comment such as "You fool".
You reside in Portugal and seem to think that you are outside of the law, well you're not. You have a responsibility to behave and work to certain safety standards; the same that we all within the EU have to.
It appears that this type of work ethic is beyond you however so we will just have to sit here in the distance hoping that you will see light and behave like a grown up person and not a spoilt child.Brian - Newton Abbot, Devon, UK

Re: Filling system up without vacumm
FYI Portugal does have the same laws far as refrigeration is concerned as to the building of the system.
http://www.xtremesystems.org/forums/...splay.php?f=80 < Go here, there are many people who are learning of phase in portigule at this forum, talk with them on the laws, and you will see they have a good work ethic.
Wether you wish to do it on your own to learn or save money or to brag ; you must learn to do it right no matter the reason, one is a fool to do other wise.

Re: Filling system up without vacumm
Course they are... i've made a waterchiller to my computer about an year... i've read about the things and i've done my home work and i've manage to do an R134a compresore with the correct cap tube to get some water to 0º then a water pump gets that water to my PC CPU....
anyway AC units are new to me...
but if you think that the portuguese on those foruns make thinkgs by the book youre wrong... the time that i've pass on those phase change, xtreme cooling foruns and stuff... i've seen nasty things... like triple EVACS with R134a or wrost gas... nitrogen ? wtf is that ? -> for the most people... fill it up with gas evac then again evan then again... its preaty mutch that... and i think that would be the same everyhere...
i saw kids puping R12 systems to air just to get the compresor to do their phase change cooling system...
i've writen some concern posts about that no one listen... everybody sayin great post etc etc but nobody gives a damn....Last edited by MaDiNfO; 17-07-2006 at 11:25 PM.

Re: Filling system up without vacumm
Actually we do, so far any one who would post about releasing R-12 would get there balls put in a vice, as for nitrogen that IS the proper way, FYI you at this very moment are breathing in over 79% nitrogen and humans have been for the last couple million years, the planet has been mainly nitrogen laden for trillions of years (If you haven't guessed by now it is the most common element on earth, and pretty much totally inert)
A/Cs are a chiller, only they chill air, same type of brains must be used, you obviously didn't learn what you where supposed to if you can't make the connection. So go to the site I listed and learn the basics! Until you fully understand how the cycle works and the principle behind the system how exactly do you intend on being competent to look at one let alone work on it ????
Learn the concept properly! & good for you that you managed to patch a unit together; that says nothing how ever, but your understanding says it very clearly, and that is you have yet much to learn be-for even thinking of trying to do any thing more.
You are sounding very foolish right now, and sounding like an idiot trying to defend your foolish sounding concepts, why did you bother to ask if you are not going to listen! thats the part that makes me pissed, you ask a group of people who took the time to learn this then totally ignore their answerers, so why the F--k did you bother asking in the first place!
You asked, our answer was, either
A: You take the time to learn to do it properly and learn what procedure you need to follow or
B: Hire a proper pro to do itLast edited by frank; 18-07-2006 at 07:11 PM.
