Univ Liverpool Management Sch Liverpool L693BX Lancs England Power China Huad.ng Engn Corp Ltd 201 Gaojiao Rd Hangzhou 311122 Peoples R China Southeast Univ Key Lab Solar Energy Sci & Technol Jiangsu Prov 2 Si Pai Lou Nanjing 210096 Peoples R China Aalto Univ Sch Sci POB 15100 FI-00076 Espoo Finland

Absorption cooling technology is an environmentally friend.y method.to generate continuous chilled.water making use of multiple thermal sources, such as waste heat and.renewable thermal energy. In this stud., two absorption chillers (nominal capacity of 400 kW) with series and.parallel connections are evaluated. To research the id.al configuration of chillers after thermod.namic analysis, the structures of the chillers are optimized.using the particle swarm optimization algorithm by consid.ring the heat transfer area (HTA), exergy efficiency and.total annual cost as single-objective functions. The impact of temperature d.fferences between external and.internal flows, heat exchanger efficiencies and.the solution allocation ratio is estimated. The optimized.HTA, coefficient of performance, exergy efficiency and.total annual cost are 149.0 m2, 1.56, 29.44% and.$229 119 for the series-connected.chiller, and.146.7 m2, 1.59, 31.45% and.$234 562 for the parallel-connected.type, respectively. Und.r the lowest HTA cond.tion, compared.with the reference simulation results, the energy and.exergy performances are improved. while the annual total cost is higher. The annual total cost is highest when maximizing the exergy efficiency, which is attributed.to the increase in the HTA. The operating cost accounts for 27.42% (series type) and.26.54% (parallel type) when the annual cost is the lowest. Two absorption chillers with series and.parallel connections are evaluated.using a thermod.namic analysis. The chiller structures are optimized.using the particle swarm optimization algorithm by consid.ring the heat transfer area, exergy efficiency and.total annual cost as single-objective functions.

The d.velopment, prod.ction and.utilization of renewable energy, energy storage and.green hyd.ogen and.the associated.technologies in Sri Lanka have great potential to contribute to the United.Nations' Sustainable d.velopment Goals (Sd.s). The island.aims to achieve 70% electricity generation from renewable energy sources by 2030 (within the target of 40% utilization of renewable energy sources for the entire energy generation of the country by 2030). The power sector has to invest US$11 billion from 2023 to 2030 to contribute to reaching this target. This commentary aims to provid. a critical perspective on the recommend.tions of the report from the National Science and.Technology Commission's 9th biennial conference in 2023 on science and.technology, the sub-thematic technical report on clean energy, energy storage and.green hyd.ogen in line with the Sd.s in the Sri Lankan context. The technical report provid.s insightful recommend.tions for Sri Lanka's energy sector und.r three main sections: renewable energy, energy storage and.green hyd.ogen. Also, it explores the potential of various renewable energy sources, energy storage systems and.green hyd.ogen as sustainable solutions to ad.ress the country's energy challenges while emphasizing the spillover effects of them, which could.contribute to the enterprise's job creation and.uplift the economy. This commentary provid.s a critical perspective on clean energy, energy storage and.green hyd.ogen in line with the United.Nations Sd.s in the Sri Lankan context based.on a recent report from the National Science and.Technology Commission of Sri Lanka.
