Scientists led by China’s Dongguan University of Technology have proposed a novel control approach for water-to-water heat pumps that uses carbon dioxide (CO2) as refrigerant. The model-based ...

Tequs said its new plug-and-play heat pump can deliver up to 90 C of heat for space heating, air conditioning, and domestic hot water ... The heat pumps use R744 (CO2) as a refrigerant and ...

Transcritical carbon dioxide (CO2) refrigeration and heat pump systems are gaining attention as efficient and environmentally friendly alternatives to traditional refrigeration technologies.

How can CO2 actually help us keep the planet cooler? When it's the refrigerant in a heat pump! And these heat pumps can warm your house while they heat your water. All while being more than twice as ...

Consider Florida, where temperatures are hot and humid ... fossil-fuel furnaces and water heaters that use natural gas and heating oil, which emit CO2 directly. Heat pumps also are more efficient ...
