Refrigeration Process Library

Overview
107 Available Units
Example Projects

The Refrigeration Process Library (Frigo_Lib) is a model library that enables its users to model a wide range of refrigeration, cooling and heat pump processes.

The Refrigeration Process Library allows you to design and analyze:

  • Absorption refrigeration processes
  • Vapor compression processes

It also allows to include secondary refrigerant systems into the process models. The library contains models for both design and off-design analysis.

Physical Properties

For vapor compression systems, physical properties are calculated using REFPROP, the Reference Fluid Thermodynamic and Transport Properties Database of NIST (U.S. National Institute of Standard and Technology).

Aqueous solutions with a range of additives are available as secondary refrigerants.
