Acid in York heatpump split system

TH3 M0L3

Serious

Yes, the motor windings might be rated at 105 deg, but the compressor is not designed to work at this temperature. This is the temp that the windings can tolerate, but prolonged exposure to these temps is bad for the comp.

The components to form the acid is the hydro-fluorine, it forms Hydrofluoric acid...

The carbon will carbonise on the metal components of the compressor at high temp leaving the hydro-fluorine to become unstable. I agree that the hydrofluoric acid is held in h2o in solution, but it is only in solution in the h20. It does not need the h20 to form...

For an engineer you write very simplistically when you describe contamination formation.

Plus i have to take issue with the accuracy of some the points you touched on.

I am finding it difficult to take you seriously. My son is an electrical engineer
and he could have phrased your comments much better and more correctly and he only has an entry level technician's comprehension of of refrigeration theory.

You should probably avoid the internet then, you'll run into a lot of them

I am quoting a figure that I got from the F-Gas certification I just acquired.
I am not sure of your locality, but as of 4 July 2011 here in the UK it will be illegal to ply our trade without the F-Gas certificate.

Logic states that Warranty claims for comps installed on products in a factory environment such as chillers/ ac units/ fridge packs etc, are far lower than compressors sent directly to the end user for replacement.

The standard of manufacturing compressors is higher than you'd think. The technology available today increases the quality of the parts produced, reducing their failure rate.
Do you really think the manufacturers would sell inferior products? Nobody would buy their stuff.

Well get your son to comment then....

If you want to get personal mate, you're looking in the wrong place!
I have come on here in good spirit and don't need idiots such as yourself to give me grief.

If you think you or your son know it all, share a bit of your knowledge with those you deem less intelligent than you and your ilk.
Or, and I think this is a more accurate statement, you know nothing and resort to personally insulting others by picking holes in their theories.

I suspect you only patrol these forums because you can hide behind your anonymity. Why not challenge yourself, and prove to us that you have got what it takes by going to a real refrigeration forum such as refrigeration-engineer dot com. At least their people are not as arrogant as you!

I guarantee you that you, oh and lest I forget your son, will be out of your depth!!!

Good luck!


edit:

If I was trying to write a thesis on refrigeration contamination I would not be publishing it here. This forum not only attracts qualified engineers, but people who know nothing or very little of our trade. If I were to get over-technical I'd bore half the people and scare them away.

Time and a place for everything mate!

Is the system still working?

Watch out! I hear my avatar is a well known British Gentelman and Knighted by Her Majesty.

You might wake up one late evening to find the dark character he played looking for a mid-night snack.

We welcome our British Cousins enthusiastically. Just giving you a hard time.
No harm no foul intended.

Long live Chris Lee!!!

Their equipment, and I can only talk about their chillers, is generally ok. It is the after sales service, and technical support dept that lack what it takes.

The last time I called technical I was told the dept was dissolved, and all the tech ,manuals are available to download from their website. If the problem still could not be sorted then we'd have to place a service call and be charged for it.

There is not a lot we can't do to them ourselves, but when it comes to the software then they have us by the short and curlys....

All I wanted was for them to confirm the password to get into the config menu!
