Air conditioning/air cooling systems are necessities of the modern urban world. These applications require huge power and have an adverse environmental impact because of the ozone-depleting coolants used. Saving electrical energy for compressors is made possible by redesigning the prime movers. Interdisciplinary approaches such as electrical engineering, mechanical engineering, thermal science, and solar energy produce electrical energy, which drastically saves more energy than the conventional system. This system converts solar radiations to heated steam to heat exchange to convert liquid coolant to vapor to produce a cooling effect using low energy. The experiment is conducted in a 1Ton conventional vapor compression system using a low-power consumption system built with an ‘ejector-based cooling system’ and ‘Scheffler concentrator-based heating system.’ The results reveal that 80% of energy is saved using unconventional interdisciplinary approaches in the subsystem design. © 2021 S Suyambazhahan, Tatek Temesgen, Anita A.
