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 ...

Hussmann Corp. recently unveiled a new refrigeration system that is charged with environmentally safe propane (R-290), a natural refrigerant. The new line, MicroDS, is available for low- and ...

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 ...

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 ...

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 ...

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, ...

Currently heat pump manufacturers are mainly focusing on cost reductions and sustainable refrigerants. In the project “LC150” (Low Charge 150 g), the Fraun-hofer Institute for Solar Energy Systems ISE ...

IN discussing the precautions required when liquefying propane for use as a refrigerant for biological specimens, J. L. Stevenson 1 points out, and correctly, the necessity for preventing the ...
