Abstract
Penelitian ini bertujuan untuk membuat simulasi sistem pendingin ruangan yang memanfaatkan sinar matahari dengan metode single-effect absorption refrigeration menggunakan beberapa variabel absorben-refrigerant, serta menganalisa Coefficient of Performance (COP) untuk setiap variabel absorben-refrigerant dan membandingkan efektifitas dari setiap variabel absorben-refrigerant yang digunakan. Variabel absorben-refrigerant yang digunakan dalam penelitian ini bergantung pada sifat kimia dan termodinamika dari working fluid (absorben-refrigerant) yang digunakan.. Langkah yang dilakukan meliputi pengumpulan dan pengolahan data dari literatur kemudian melakukan simulasi sistem pendingin ruangan baik sistem komersial (menggunakan energi listrik) maupun sistem yang memanfaatkan sinar matahari dengan menggunakan software Aspen Plus. Selanjutnya melakukan simulasi untuk setiap variabel working fluid dan melakukan perhitungan COP masing-masing variabel, kemudian menganalisa dan membandingkan efektifitas setiap variabel yang diteliti dari aspek COP dan ekonomi dengan sistem pendingin ruangan konvensional. Berdasarkan hasil penelitian, dapat disimpulkan bahwa solar air conditioning mampu menghemat kebutuhan listrik sebesar 49,8% hingga 67,2% dibandingkan AC komersial. Selain itu, berdasarkan analisa COP, nilai COP sistem solar air conditioning tertinggi terdapat pada sitem dengan working fluid LiNO3-NH3 dengan komposisi 70% refrigerant dan 30% absorben.
==================================================================
The purposes of this research are to do a system simulation of air conditioning utilizing solar energy with single effect absorption refrigeration method, analyze the coefficient of performance (COP) for each absorbent-refrigerant variable and compare the effectivity of every absorbent-refrigerant variable used. Absorbent-refrigerant (working fluids) variables used in this research depend on its chemical and thermodynamics properties. Steps in this research are including data collection and tabulation from literature and do a simulation of air conditioning system both commercial air conditioning system (using electrical energy) and solar energy air conditioning system with Aspen Hysys software. Next, run the simulation for each working fluid variables used and calculate the COP for each variable. Subsequently, analyze and compare the effectivity of all variables used from COP value and economical point of view with commercial air conditioning system. From the result of the simulation, can be concluded that solar air conditioning can achieve 49,8 % up to 67,2 % of energy savings than commercial air conditioning. Furthermore, from the calculation of COP, the highest COP value is achieved by solar conditioning system with LiNO3-NH3 as working fluid where 70% of the composition is the refrigerant and 30% of absorbent.
