Thermodynamic Properties of R-14

Hello to all

Can any one provide me with Pressure tempreture charts of R-14

Gee, I guess that was simple enough. Huh, Prof. ;)

hehe

Got a chart for R13B1, Prof? I haven't been able to find one online.

thanks Prof. for the help I was unable to find one on the net

Thanks, Prof. :D

Is there anywhere tables on other properties (enthalpy, enthropy) of all known refrigerants? I found the software on www.atofina.com, but other manufacturers have not such programs.

Does refrigerant properties differ from one manufacturer to another so much that it needs to take into account?

Coolpack might help you out. It's free and it's good.

Regarding the refrigerants: R404a is R404a. R134a is R134a. R410A is R410A. Regardless of the manufacturer: the Rxxx number stands for a certain composition, and thus known properties.
