“Scientists have developed a magnetocaloric heat pump that matches conventional systems in cost, weight, and performance, eliminating harmful refrigerants. By optimizing materials and design, the pump achieves comparable power density, offering a greener and efficient alternative for heating and cooling.”
What about the environmental impact of constructing them? It seems strange that this is missing from the article since the entire point of replacing existing compressors is to eliminate some of the emissions associated with cooling.
Edit: first line was missing “constructing”
Aren’t modern heat pumps working with Propane and Butane?
The main problem with these systems is efficiency. Compressor based refrigerators can achieve around 60% efficiency, while magnetocaloric pumps are around half. Until they reach that level, these pumps are going to remain niche technologies.
This is huge for sustainability. Magnetic cooling could eliminate those nasty refrigerants that wreck the ozone layer, plus they’d probably last way longer since there’s fewer moving parts. Hope it becomes affordable soon
