Adaptation 2025: ‘Novel Technology’ May Cut Energy Use of CO2 Refrigeration in Hot Climates by 14%, Says Study

In hot climates a “novel technology” could reduce the energy consumption of commercial CO2 (R744) refrigeration systems by up to 14% compared to standard setups, according to new research from the University of Southern Denmark (USD).The concept integrates a pressure booster device and an air-cooled gas cooler installed behind the existing heat rejection component and replaces the high-pressure expansion valve with an expander. Modeling demonstrated potential energy savings compared to conventional CO2 systems in Seville, Spain, and New Delhi, India. In Seville, average summer highs are between 35 and 40°C (95–104°F), and in New Delhi they frequently exceed 44°C (111.2°F).Read the full story on NaturalRefrigerants.com.
