A refrigeration system for supermarkets using natural refrigerant CO2 [PDF]
This paper describes a refrigeration system using a natural refrigerant that has been developed to reduce significantly both direct and indirect greenhouse gas emissions. The new system uses both R-404A and CO 2 (R-744) as refrigerants. The new system has very low global warming potential compared with conventional HFC systems which reduces ...

Thermodynamic Analysis of Ozone-Safe Low Boiling Working Media for Turbo-Expander Plants
The article considers 46 low-boiling working media (LBWM) with zero potential for ozone layer destruction. Out of them, 14 ones are single-component hydrofluorocarbon refrigerants, 28 ones are multi-component mixtures of hydrofluorocarbon refrigerants ...

Carbon dioxide as a natural refrigerant [PDF]
In the beginnings of mechanical refrigeration, at the end of the nineteenth century, carbon dioxide was one of the fi rst refrigerants to be used in compression-type refrigerating machines, later gaining widespread application mainly onboard refrigerated ships, but common in other sectors of refrigeration as well.

Natural refrigerants are favored by the future
BACKGROUND: Reducing the harmful impact on the environment is a promising way to the development of low-temperature technology. According to the amendment to the Montreal Agreement, approved by the Russian Federation, the use of hydrofluorocarbons should be reduced by 85% by 2036.
