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. 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. Thermodynamic properties of refrigerant
mixtures are calculated based upon the widely-used NIST
Standard Reference Database 23 - NIST Reference Fluid
Thermodynamic and Transport Properties Database: REFPROP
Version 7.0. A user manual and help section is included.
