REFLEAK estimates composition changes of zeotropic mixtures in leak and recharge processes. The leak/recharge simulation program consists of three parts: 1) the pre-processing section for inputting required data, 2) the computation section which simulates leak/recharge processes, and 3) the post-processing section to display calculated results and to print or store data and graphs.
REFLEAK offers the following:
Calculated vapor and liquid compositions are displayed in a graphic format. Additional tabular data includes temperature, pressure, volumetric quality, liquid specific volume and vapor specific volume for each 1% of mass leaked throughout the process. Output data can be saved and printed. A Help Menu and User’s Guide with simulation examples are included.
Compared to previous versions, this version 6.0 of REFLEAK is based on NIST Standard Reference Database 23 - NIST Reference Fluid Thermodynamic and Transport Properties Database: REFPROP Version 10.0, with updated representation of refrigerant thermophysical properties and extended list of refrigerants.
