| # Wrapper of REFPROP for C# | ||
|
|
||
| The files in this directory demonstrate how to call REFPROP routines from a C# program for High level API. This example can be used to easily and quickly create your own C# program that uses RefProp. | ||
| Cancel changes | ||
|
|
||
|
|
||
| ## To Use Wraper | ||
|
|
||
| 1. Clone the repository. | ||
| 2. Insert your project. | ||
| 3. Add references the DLL | ||
|
|
||
| 4. Create an object. | ||
| 5. Here is an example : | ||
|
|
||
| using RefpropDLL; | ||
| public partial class Refprop | ||
| { | ||
| Refprop refprop = new Refprop(); // creating object | ||
|
|
||
| string prop_1 = "T"; // property 1, T Ç Temperature | ||
| double prop_1_value = "300"; // property 1 value, for temperature in K | ||
| string prop_2 = "p"; // property 2, P : Pressure | ||
| double prop_2_value = "200000; // property 2 value, for pressure in Pa | ||
| string output_prop = "H"; // output property, H : Enthalpy (J/kg) | ||
| string fluid = "R134A"; // fluid | ||
| double output_val = refprop.Calculate(output_prop, prop_1, prop_1_value, prop_2, prop_2_value, fluid); | ||
| // this method calculates desired property. output : 424.410 J/kg | ||
|
|
||
| string phase = refprop.Phase(prop_1, prop_1_value, prop_2, prop_2_value, fluid); | ||
| // this method gives the phase state of the fluid. | ||
| // phase : Superheated gas | ||
|
|
||
| double dll = refprop.DLL_VERSION(); // this method gives DLL version. (version*10000) | ||
| dll = dll / 10000; | ||
| // dll : 10 | ||
|
|
||
| } | ||
|
|
||
| * You must already have REFPROP installed in the default location | ||
| * refprop.SetDLLPathProgramtDirectory(); this method can be used if dll will be used in the project. Sets the path : appdomain.currentdomain.basedirectory | ||
