Calculation of R22 flash volume
Thread Content
When 100 kg of R22 at 0.7 MPa is flashed to 0.2 MPa, how much of the R22 turns into the gas phase?
I don’t understand this, but aren’t the conditions you’ve given insufficient?
0.7mpa, temperature 15℃； 0.2MPa, temperature -20℃
Using HYSYS simulations, it can be seen that at 0.7 MPa and 15°C, when 100 kg of R22 is flashed to 0.2 MPa, there is approximately 16 kg of gaseous R22, with a temperature of -14.8°C.
