refrigerant weight
(OP)
Hi there
hope everybody is fine.
Please, I'd need an hint as follows.
is there a literature reference or formula in order to calculate thew weight of refrigerant contained in a condenser and an evaporator ?
Ex:
In a condenser with condensing temperature of 122F, with R410A, how much is the weight of refrigerant ?
it can't be the volume for specific weight, since I have a phase change.
Please, can anybody help me ?
thanks !

RE: refrigerant weight
Thanks for the answer.
I am afraid that I'd need more help.
My point is: I know a mass flow, but I don't know the mass or the volume that has been inputted.
Would you be so kind and make me an example of calculation ?
Thanks !
RE: refrigerant weight
The volume flow at any point is simply the mass flow times the specific volume.
Specific volume is available from tables except for saturated mixture states (eg condenser and evaporator) where quality is unknown but could be inferred as linear between 0 and 1 whit distance travelled along the heat exchange path. The section of the HX where mixed phase exists can be approximated since T will be constant throughout that section.

@ gruntguru
I have a massflow (mass/unit of time).
1) It is not clear to me how to pass from mass flow to mass.
2) shall I then make an integration along the condenser length on quality ?
3) how shall I consider the calculation for refrigerants with glide ?
Many question, but thanks to your help things are getting step by step more clear !!
