Processing R134 Tables in a VI

Hi you all! I hope you´re all fine

 

I´m working in the digitalization of a Refrigeration Bank. It´s for testing and experimental purposes (mechanical Engineering students). I made the VI that I considered that fits for the case. It´s the one in the attachment. I´m receving 10 values from the bank (5 for temperature and 5 por Pressure). As you may know, for Thermodynamic purposes I have to use some tables (R134 tables) so i can get the enthalpy in every point i have the sensors. That´s just for calculations on the Heat Rate.

 

I have everything set up, but I don´t know how to make Labview "recognize" (I know it´s not the correct word for the case) or analyze somehow those tables so I can get the enthalpy for each point with the values i´ll be reading in LABVIEW.

 

I´ve been searching for this a lot, and i haven´find any guide or possible help. I hope i could get it from you!

 

Thanks a lot and best regards

Hey Carlos!

 

Try this VI. Is this what you've been looking for?

 

You enter with values of Temperature and Pressure and you get the value of Enthalpy based on a Table Analysis.
