A combined thermo-mechanical refrigeration system with isobaric expander-compressor unit powered by low grade heat – Design and analysis
(
Elsevier
, 2020 , Article)
Refrigeration and air conditioning systems consume about 17% of the world-wide electricity and their conventional refrigerants cause ozone depletion and global warming. In this study a novel thermo-mechanical refrigeration ...
Techno-economic assessment of low-carbon hydrogen exports from the Middle East to the Asia-Pacific, and Europe
(
Taylor & Francis
, 2023 , Article)
Hydrogen has the potential to play a major role in the global energy mix in the future and to achieve carbon-neutral targets by 2050. However, there is a lack of studies that investigate the economic feasibility of ...
Energetic, economic, and environmental analysis of solid oxide fuel cell-based combined cooling, heating, and power system for cancer care hospital
(
Tsinghua University
, 2022 , Article)
In this study, energetic, economic, and environmental analysis of solid oxide fuel cell-based combined cooling, heating, and power (SOFC-CCHP) system is proposed for a cancer care hospital building. The energy required for ...
Comprehensive thermoeconomic, exergoeconomic, and optimization analyses of direct oxy-combustion supercritical CO2 intercooled and reheated cycles under design and off-design conditions
(
Wiley-Blackwell
, 2022 , Article)
This study presents comprehensive energetic, exergetic, exergoeconomic, and economic (4E) performance analyses for four direct oxy-combustion (DOC) supercritical carbon dioxide (sCO2) power cycles at design, off-design, ...
Experimental investigations on the performance of a thermo-mechanical refrigeration system utilizing ultra-low temperature waste heat sources
(
Elsevier
, 2023 , Article)
Experimental studies that investigate the utilization of ultra-low temperature (between 48 °C and 120 °C) waste heat, which forms 25 % of the global unrecovered waste heat, to drive thermal cooling systems are rare. Thus, ...
Systematic thermodynamic approach for designing mixed refrigerants used in hydrogen precooling process
(
Elsevier
, 2022 , Article)
Designing an optimal mixed-refrigerant (MR) composition for any cryogenic refrigeration process plays a key role in the process overall performance. However, the existing approaches of developing mixed-refrigerants for ...

This paper introduces a novel hybrid and interactive solar system to generate electricity and produce desalinated water. The system consists of a Stirling engine driven by concentrated solar radiation and cooled by saline ...
Combined direct oxy-combustion and concentrated solar supercritical carbon dioxide power system—Thermo, exergoeconomic, and quadruple optimization analyses
(
Hindawi
, 2022 , Article)
For the global future energy systems, concentrated solar power (CSP) and direct CO2 capture systems are of the most important key technologies, however, each of these systems has shortcomings. This study addresses the solar ...
Experimental investigation on the performance of a novel thermo-mechanical refrigeration system driven by an expander-compressor unit
(
Elsevier
, 2022 , Article)
Operating thermos-mechanical refrigeration (TMR) ejector-based and organic Rankine cycle-based refrigeration systems at ultra-low temperature heat source (60 °C to 100 °C) is challenging and limited by their low coefficient ...
A novel solar integrated distillation and cooling system – Design and analysis
(
Elsevier
, 2020 , Article)
To meet the high cooling and fresh water demands in hot and arid regions, a novel integrated solar cooling and solar distillation system is introduced. The system consists of a solar ejector cooling system integrated with ...
