Résumé

Hotels in India typically rely on synthetic refrigerant-based chillers for space cooling and diesel-fired water heaters for hot water production—both energy-intensive solutions that contribute significantly to global warming. Transitioning to natural refrigerants like CO2 is a promising alternative, but this shift faces several challenges in India, including high ambient temperatures, limited technical expertise, resistance to adopting new technologies, and a shortage of skilled professionals. Demonstrating the real-world performance of such systems is essential to overcoming these barriers. This paper presents and discusses the first set of field data from a CO2 heat pump recently implemented in a hotel located in a tropical region of India. The system successfully met its design goals, producing hot water at 80 °C while simultaneously providing chilled glycol-water at 2 °C. The results indicate that CO2 based systems can effectively meet both heating and cooling demands in warmer climates, offering a sustainable alternative for the hospitality industry.
