Dear rwoolhou
Thankyou for your answer, I import the R404 from NIST Table through command, and its said than we only could define the refrigerant between vapour or liquid. I define the R404a as liquid and when i choose it as Phase 1, I confused what should i choose for Phase 2. As you can see if I choose R404a as phase 2 from the material, it also define as liquid not vapor.
