Combined small-scale power installation forgeneration of the heat, electricity, and moisture from air
(2021) Zhang, Haobo
In this paper a сombined small-scale power installation composed of a cogeneration system, and an ejector cooling cycle intended for water harvesting from atmospheric air is proposed. The cogeneration system is a combined heat and power system for electricity generation, heat production, and hot water supply. This system includes a microturbine and two heat recovery units. The water harvesting is provided by using cooling effect obtained in an ejector cooling machine (ECM). The ECM is driven by hot water obrained in the cogeneration system and using refrigerant R1233zd(E). The paper describes a theoretical analysis of the сombined small-scale power installation and shows the effect of the operating conditions on thesystem performance. The results show that the proposed installation has high energy efficiency and provides significant savings in energy resources.
