Low-GWP Alternative Refrigerant Blends for HFC-134a

September 7, 2018
Author(s)
Piotr A. Domanski, Mark O. McLinden, Ian H. Bell, Gregory T. Linteris
The goal of this study was to identify non-flammable, non-toxic, low global-warming-potential (GWP) replacements for HFC-134a in an air-conditioning system that would maintain the energy efficiency and capacity. A prior exhaustive work demonstrated that

Review of Refrigerants Evolution

June 20, 2018
Author(s)
Piotr A. Domanski, Mark O. McLinden, Andrei F. Kazakov, J S. Brown, Riccardo Brignoli, Jaehyeok Heo, Janusz Wojtusiak
The presentation discusses the application of refrigerants from the beginnings of ‘artificial cold’ in the era of industrial revolution to the currently used fluids, and the refrigerant options in response to environmental concerns. The outlook for new

Low-GWP Refrigerants; Options and Issues

April 11, 2018
Author(s)
Piotr A. Domanski, Riccardo Brignoli, J S. Brown, Andrei F. Kazakov, Mark O. McLinden
This research explored the possibilities for refrigerants having low global warming potential (GWP) with a particular focus on high-pressure applications. The search for suitable refrigerants relied on screening of a comprehensive database using filters of

LOW-GWP REFRIGERANTS FOR MEDIUM AND HIGH-PRESSURE APPLICATIONS

September 19, 2017
Author(s)
Piotr A. Domanski, Riccardo Brignoli, S J. Brown, Andrei F. Kazakov, Mark O. McLinden
The merits of an alternative refrigerant are established based on many attributes including environmental acceptance, chemical stability in the refrigeration system, low toxicity, flammability, efficiency and volumetric capacity. In an earlier work, these

LOW-GWP REFRIGERANTS: PERFORMANCE ASSESSMENT AND SELECTION TRADEOFFS

CYCLE_D: NIST Vapor Compression Cycle Design Program, Version 5.1.1; Users Guide

March 9, 2017
Author(s)
Piotr A. Domanski, J S. Brown, Eric W. Lemmon
The CYCLE_D package simulates vapor compression refrigeration cycles that use pure refrigerants or blends of refrigerants. The model can simulate a basic subcritical or transcritical refrigeration cycle, both with or without a liquid-line/suction-line heat

Limited options for low-global-warming-potential refrigerants

February 17, 2017
Author(s)
Mark O. McLinden, J S. Brown, Riccardo Brignoli, Andrei F. Kazakov, Piotr A. Domanski
Hydrofluorocarbons, currently used as refrigerants in air-conditioning systems, are potent greenhouse gases, and their contribution to climate change is projected to increase. Future use of the hydrofluorocarbons will be phased down and, thus, replacement
