Summary

India's heating, ventilation, air conditioning, and refrigeration (HVAC&R) industry still mainly employs synthetic refrigerants, exacerbating global warming. Promoting natural refrigerants may facilitate the transition to clean, sustainable heating and cooling options. However, in addition to the technical difficulties brought on by high ambient temperatures, non-technological impediments such as lack of expertise with the technology, general hesitance to new technology, and a shortage of appropriately experienced experts and installers hamper the adoption of the latest technologies. The Future Refrigeration India: INDEE+ project aims to increase confidence in the HVAC&R sector by implementing and demonstrating some natural refrigerant-driven heating and cooling systems. Ejector-supported 140 kW R744 systems is proposed for a hot water supply unit for a large school kitchen. The system is designed to meet both the heating and cooling loads simultaneously. The second investigation focuses on operating a 350 kW CO2-NH3 cascade freezer in a fish processing factory. The third unit under development is an on-board refrigeration system that produces ice from seawater using R290 (propane). This paper initially covers the modelling, simulation, and theoretical performance evaluation of the designed systems. Further validation of the models with data from the industrial areas is presented. The outcomes of this demonstration work in real industrial scenarios will serve as guidelines to assist the transition to more environmentally friendly heating and cooling systems in India.
