CO2 (R744)-based air source heat pumps are optimal for centralized heating applications up to 10MW (2,843TR), according to Kim Gardø Christensen, CEO at Fenagy, a Danish manufacturer of heat pumps and refrigeration systems.
Christensen delivered his remarks during a presentation in an HVAC and heat pumps session at the ATMOsphere (ATMO) Europe Summit on natural refrigerants. The conference took place November 15–16 in Brussels and was organized by ATMOsphere, publisher of R744.com.
Christensen previously stated that CO2 heat pumps are “really good” for district heating applications and the best available technology in the 0.5–5MW (142–1,422TR) capacity range.
