Re: Weight
My understanding of the question was for each system ie every system irrespective of size,gas etc. F-gas relates to only those gases covered and only for systems above 3kg, which is why I asked for a link.

Re: Weight
I agree, I have the misfortune of looking after a site with over a hundred versatemp units, and was informed then that the register only applies to systems 3kg and above.
I guess that we shall all find out when we sit the new safe handling exams!!

Re: Weight
Don't you think that gas weight depend on density, which depends on temperature. And, what with mixture of gas and liquid in pipe?
You could use Coolpack software for calculation of liquid and gas flow in pipes and fittings! From that you could estimate/calculate weight.

Re: Weight
To enable the calculation of weight Kg in pipework (R407C) to be added to the condenser - compresser. Is there not a chart giving the weight for various diameters of pipes listing the kg/m in a liquid line.

Re: Weight
If you have Excel, it is easily calculated from pipe dimensions and density.
Tables you could find here at page 11:

Re: Weight
That's correct and 6 kg and above for factory hermetic made units (like monoblocs, chillers,...).
I'm a jury member and chairman of the Jury in th Dutch speaking part of Belgium, so if you have questions...
You can find everything you need to know in the new EN378-2008.Last edited by Peter_1; 25-01-2009 at 08:00 AM.

Re: Weight
Link: EN378-4:2008, Appendix D. - D5
Translated from Dutch: The applications must be controlled on leakage within 1 month after repair of the leak to ensure that initial repair was effective.It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

Re: Weight
Take a look at this calculator / spreadsheet off the Defra website.
http://www.defra.gov.uk/environment/...y/quantity.htmIf in doubt read the instructions. If still in doubt follow them.
