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.

Regulations are accelerating low-GWP refrigeration adoption. While CO₂, A2Ls, and propane offer viable paths, each has unique ...

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 ...

Propane heat pumps for indoor use in single-family homes are now one step closer to commercialization. Germany’s Fraunhofer ISE has successfully developed a model of a heat pump refrigeration circuit ...

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 ...

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 ...
