residue R404a
(OP)
Hello, experts
I use for work R404A from cylinders.
Each cylinder contain 10.9 kg of refrigerant.
In liquid phase its components R125 / R143a / R134a is in ratio 44% / 52% / 4%
When I charge refrigerator ,
amount and pressure of refrigerant in the cylinder will decrease ,
and once some components will vaporize in cylinder,
and ratio between components get broken.
So a substance in the cylinder will not be R404a.
In view of the aforesaid let me ask some questions:
How much kg of refrigerant I can take from cylinder ?
What should I do with residue blend ? Can I use it for charging?
Thanks for any advice

RE: residue R404a
If you are doing something that requires very exact performance from your equipment, there may be a small difference.
The refrigerant manufacturers have lots of technical data available on their web sites, and even more if you call the tech support center.
If you really need to know how the change will affect your equipment, you need to test your equipment.

How you recovery residue refrigerant?

The cylinders I purchase have liquid (red) and vapour (blue) valves for accessing refrigerant. If you don't have a liquid valve, that is a valve with a dip tube, the charging cylinder can be turned upside down to ensure liquid is in your charging hoses.
Once a blend separates, it is a very expensive propostion to determine the composition of the altered state. Economically, you should start with more liquid R404a.
