Liquid receiver

[frank]

how much r134a in kgs will go into a reciever of capacity 0.02 cubic metres and how is it calculated.

Are we talking liquid or vapour?

The density of R134a vapour is 14.423kg/m3 @ 0C (32F) so you could fit 0.28846kg into a volume of 0.02m3 (14.423*0.02)

For liquid @ 0C the density is 1.2949kg/l so you could fit 25.898kg into 20litres (0.02m3).

Obviously, at different temperatures the results will be different as the density alters.

You need to look at the Saturation Tables for R134a and do the maths for your maximum system temperature.

If you are looking to put this into practice though, you must allow at least 20% volume capacity for liquid expansion, that is, reduce your final calculated liquid figure by 20% to allow for expansion.
