Abstract

Penelitian ini bertujuan untuk menganalisis energi dan eksergi dari sistem gabungan AC dan ORC menggunakan berbagai jenis refrigeran. Penelitian ini dilatarbelakangi oleh isu lingkungan terkait kerusakan lingkungan yang disebabkan oleh limbah panas dari sistem AC.
Metode penelitian yang digunakan adalah simulasi menggunakan perangkat lunak EES (Engineering Equation Program). Parameter sistem AC divariasikan untuk 36 kombinasi refrigeran AC-ORC dengan tujuan menghitung kinerja sistem AC-ORC menggunakan pendekatan energi dan eksergi. Data yang dianalisis menggunakan pendekatan kuantitatif dengan membandingkan performa subsistem AC dan ORC dengan refrigeran yang berbeda.
Hasil analisis termodinamika menunjukkan bahwa pasangan fluida R600a- R141b dipilih untuk siklus Rankine organik dan integrasi AC. Koefisien kinerja kombinasi (COP Kombinasi) dari sistem terintegrasi berdasarkan suhu chilled water meningkat dari 3,329 menjadi 4,728. Sistem siklus Rankine organik mampu menghasilkan daya turbin sebesar 1,531 kW dengan efisiensi termal sebesar
3,068%. Sistem gabungan AC-ORC terintegrasi beroperasi dengan efisiensi eksergi sebesar 30,34%.

This study aims to analyze the energy and exergy of a combined AC and ORC system using various types of refrigerants. This research was motivated by the problem where heat waste from the AC system is one of the causes of environmental damage caused by waste heat from the AC system.
The research method used is simulation using EES (Engineering Equation Program) software. AC system parameters were varied for 36 AC-ORC refrigerant combinations with the aim of calculating the performance of the AC-ORC system using energy and exergy approaches. The data were analyzed using a quantitative approach by comparing the performance of AC and ORC subsystems with different
refrigerants.
The results of thermodynamic analysis showed that the fluid pair R600a- R141b was selected for the organic Rankine cycle and AC integration. The combined performance coefficient (COP Combination) of the integrated system based on chilled water temperature increased from 3.329 to 4.728. The organic Rankine cycle system is capable of producing turbine power of 1.531 kW with a thermal efficiency of 3.068%. The combined integrated AC-ORC system operates with an exergical efficiency of 30,34%.
