Theoretical study and design of small-scale cascade CO2 sub-critical mechanical compression/ammonia ejector refrigerating unit

, 2010
In this paper an innovative micro-trigeneration system composed of a cogeneration system and a cascade refrigeration cycle is proposed. The cogeneration system is a combined heat and power (CHP) system for electricity generation and heat production.
