Feasibility and Performance Study of Solar Combined Heat and Power System with Absorption Heat Pump in Uzbekistan

Abstract: In this paper, a case study of solar combined heat and power (CHP) system is carried out to assess its feasibility and investigate its dynamic performance using the weather and solar radiation data of Parkent region of Uzbekistan. In order to improve the overall utilization level of solar energy, both the waste heat recovery technology based on the absorption heat pump (AHP) and the advanced regenerative power cycle are well developed with the principle of cascade energy utilization in the solar CHP system. Following the solar CHP system’s control and operation strategy, the thermodynamic performance is effectively presented by the TRNSYS simulation program. As a promising approach, the solar CHP system can produce both continuous heat and enhanced electricity power for consumers with multiple benefits and high-efficiency solar energy utilization. © 2020, Allerton Press, Inc.
