Natural refrigerants for refrigeration and air-conditioning systems

open access: yesApplied Thermal Engineering, 1997
In the past, several natural working fluids were used in refrigeration and air-conditioning systems. However, the appearance of CFCs caused a drastic reduction in the utilisation of those fluids. Understanding of the environmental damage of CFCs focused attention on alternative refrigerants. From these, the ones that have minimum (or nil) environmental

Selection of suitable natural refrigerants pairs for cascade refrigeration system

Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2013
This study presents thermodynamic analyses and optimization of a two-stage cascade system employing a choice of eight natural refrigerants leading to the most suitable refrigerants pair for wide ranges of operating temperatures; the optimal pair was based on best system performance (cooling coefficient of performance) as well as best volumetric cooling
