As the industry takes a look at refrigerants beyond HFCs, a lot of attention has been focused on CO2 (carbon dioxide). Another refrigerant that has been looked at over the years is R-290 - propane.

Using propane as a refrigerant in air conditioners could avoid around 0.1°C of global warming by the end of the century. It would be a significant reduction considering that, to achieve the Paris ...

Current severe heatwaves that will likely increase in severity and frequency in the future are driving a rise in the use of air conditioners, threatening the environment with their high energy ...

Not just for barbecues, some companies are switching over completely. The reviews of the new report from the UK's Committee on Climate Change have been mixed; I complained about its reliance on ...

Scientists at Germany’s Fraunhofer Institute ISE and a consortium of heat pump manufacturers have achieved a new efficiency record in their development of a low-refrigerant propane refrigeration ...

Manufacturers of hermetic compressors are turning their attention to alternative refrigerants that could represent a long-term solution to ongoing to government regulation. Although it’s commonly ...

In the transcritical refrigeration cycle, the refregierant travels through the the compressor but does not condense into a liquid, it just gets colder. Therefore, heat exchangers using copper tubing ...

There is a growing awareness across the United States of the importance of using environmentally friendly, non-toxic propane R290 as a natural alternative for commercial refrigeration equipment, ...

New research from Spain has sought to understand if dimethyl ether and ternary mixtures of carbon dioxide, dimethyl ether and butane could represent an alternative to propane in heat pump systems.

A comparison of LNG processes for tropical conditions showed that Shell double mixed refrigerant (DMR) process is a competitive alternative for the propane mixed refrigerant (C3MR) process. For both ...
