U1 - 621 PY - 2025/// CY - Islamabad : PB - SMME- NUST; KW - MS Mechanical Engineering N1 - The worldwide need for energy as well as environmental challenges have promoted the creation of sustainable power solutions. Various working fluid combinations are utilized for an Organic Rankine Cycle powered Vapor Compression Cycle (ORC-VCC) to deliver cooling applications. The selection of an appropriate working fluid significantly impacts system performance, efficiency, and environmental impact. In this study we evaluates possible working fluids to optimize the ORC-VCC system. Firstly, the Artificial Neural Network (ANN) derived models for exergy destruction (πΈπ‘‘π‘‘π‘œπ‘‘), and the heat exchanger total heat transfer capacity (π‘ˆπ΄π‘‘π‘œπ‘‘). Later on, the multi-objective optimization was conducted using the acquired models for πΈπ‘‘π‘‘π‘œπ‘‘ and π‘ˆπ΄π‘‘π‘œπ‘‘ using the Genetic Algorithm (GA) followed by Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS).The optimization result showcase Decane ORC- R600a VCC as the optimal choice for ORC-VCC system, resulting in values of πΈπ‘‘π‘‘π‘œπ‘‘ and π‘ˆπ΄π‘‘π‘œπ‘‘ resulting in value of 24.50 kW and 6.71 kW/K, respectively. From the extended analysis and optimization, the cooling capacity was found to be 41.8 kW. Meanwhile, the total cost per unit was estimated to be approximately $78710 and the payback period is 9.7 years. The research data shows how viable it is to implement biogas-driven ORC-VCC systems when providing air conditioning capabilities UR - http://10.250.8.41:8080/xmlui/handle/123456789/53145 ER -
