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…
