Blended refrigerants

[yousufrafi]

Hi friends anybody tellme.
Why not using the blended refrigerants in the flooded type systems?

[Brian_UK]

Because the other types are doing a suitable job already, why change?

[Grizzly]

I prefer Brian's answer!
But I think the correct one is because of the glide!
Oh! and expense related to the large volumes required.
To name just a few.
Grizzly

[NH3LVR]

As I understand it the fear is that the blend will change in the low side accumulator and the temperature pressure relationship will change. In other words you will have one blend in the high side and another in the low side.

I think Grizzly and NH3LVR are absoulutely right.
It depends on the temperature glide, followed of small differences in dew point and boiling point of the various blend components. In consequence you might get a separation of the different refrigerants in your system and you possibly really get an other refrigerant in the low side accumulator as in the upper side accumulator, as describet above.

What is the reason behind your questition?
I think conventionally used refrigerants in flooded systems are Ammonia, R134a and in some areas of the world still R22.
Which refrigerant do you think about?
In a few weeks w'll start testing, if R723 works properly in a screw compressor system.
Does anyone gathered experience in this matter?
