Techno-economic analysis of air source absorption heat pump: Improving economy from a Design Perspective
Energy and Buildings, 2014Co-Authors: Wei Wu, Baolong Wang, Xianting LiAbstract:Abstract The heat supply system combining a conventional boiler with an air source absorption heat pump (ASAHP) has been evaluated as having great potential in energy saving and emission reduction. However, an economic analysis needs to be performed before its wide applications. To improve the economy of ASAHP from a Design Perspective, a year-round simulation and techno-economic analysis are conducted. Results show that the energy saving rate (ESR) does not decrease much when the relative Design capacity of ASAHP is within 50–100%. At a relative Design capacity of 75% in Harbin, 35% in Shenyang, 50% in Beijing, and 50% in Zhengzhou, ESR can reach 21.6%, 24.3%, 26.2% and 26.3%. Given an ASAHP price of 1.5 CNY/W and a gas price of 4.0 CNY/Nm 3 , the payback period is 6.8, 6.6, 4.1 and 4.6 years in these four cities, at a 50% relative Design capacity. There is a conflict between ESR and the payback period, but a small sacrifice (1.5–6.0%) in ESR can contribute a great reduction (38–48%) in the payback period. The heating period and energy price in the local area, as well as the expected ESR and acceptable payback period should be comprehensively considered for a better energy efficiency and economy.

micro scale energy harvesting a system Design Perspective
Asia and South Pacific Design Automation Conference, 2010Co-Authors: Chao Lu, Vijay RaghunathanAbstract:Harvesting electrical power from environmental energy sources is an attractive and increasingly feasible option for several micro-scale electronic systems such as biomedical implants and wireless sensor nodes that need to operate autonomously for long periods of time (months to years). However, Designing highly efficient micro-scale energy harvesting systems requires an in-depth understanding of various Design considerations and tradeoffs. This paper provides an overview of the area of micro-scale energy harvesting and discusses the various challenges and considerations involved from a system-Design Perspective.
