Adaptation 2025: Integrated R600a Heat Pump Can Cut Supermarket HVAC&R OpEx by Up to 91% Compared to Gas Boiler, Study Finds

Integrating an isobutane (R600a) heat pump into a supermarket’s transcritical CO2 (R744) booster refrigeration system can cut space-heating operating costs by as much as 91% compared to a natural gas boiler, according to new research from the University of Southern Denmark.The study, which modeled the energy and cost impacts for a Stockholm supermarket, also found that replacing the gas boiler with the R600a system could lower greenhouse gas emissions by around 94%. Read the full story on NaturalRefrigerants.com.
