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:

  • Choice of simulation mode between leak only and leak/recharge
  • Choice of process between isothermal (slow) and adiabatic (fast) leak conditions
  • Choice of vapor leak or liquid leak
  • Choice of 62 refrigerants
  • Choice of any mixture, up to 5 components, comprising the above refrigerants
  • Choice of specifying the initial temperature and initial volumetric quality of charge
  • Choice of specifying the number of recharges, up to 10, and the % mass leaked after each.

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.
