Study of Combined Refrigeration System with power plant for Sustainable Environment

Abstract

 In this paper First and Second Laws of thermodynamics to different refrigeration and heat pump cycles combined with power plants has been presented. The main goal of the study is to determine how well low GWP refrigerants work in refrigeration and heat pump systems. Component-level exergy analysis is used to improve design possibilities by addressing systemic inefficiency, which is the primary cause of lost work . Reducing energy use, cutting carbon emissions, and promoting environmental sustainability are all addressed by Cold climate heat pumps that use low GWP refrigerants. Study of Biofuel based Polygeneration and Solar assisted cogeneration power plant included in this paper.

In pursuit of sustainable development and carbon neutrality, the integration of refrigeration systems with power plants emerges as a transformative solution to enhance energy efficiency and minimize environmental impact. This study presents a comprehensive analysis of combined refrigeration systems (CRS) synergistically linked with power generation units, leveraging waste heat recovery and cogeneration techniques to optimize thermodynamic performance. By exploiting low-grade thermal energy typically discarded in conventional plants, the integrated system substantially reduces greenhouse gas emissions and operational costs, promoting a circular economy approach within energy infrastructures. The research employs advanced simulation models and exergy analysis to benchmark system efficiencies across varying operational parameters and climatic conditions. Results demonstrate that the hybrid configuration not only augments overall plant efficiency by up to 15% but also achieves significant reductions in carbon footprint, aligning with global sustainability goals. This paper sets a strategic foundation for policymakers, industry stakeholders, and researchers to reimagine energy ecosystems.
