Abstract

Alat pendingin adsorpsi dengan zeolit sebagai adsorben merupakan metode pendingin alternatif. Zeolit merupakan batuan mineral mampu menyerap uap air . Proses penyerapan ini akan berhenti ketika pori – pori zeolit telah terisi penuh oleh uap air. Zeolit dapat di aktifkan dengan proses regenerasi. Metode regenerasi dengan melakukan percobaan regenerasi kalsinasi sumber panas matahari dan sumber panas oven bertemperatur 150oC, regenerasi gabungan kimia dan kalsinasi menggunakan larutan NaOH dan HCL untuk merendam zeolit yang kemudian dilakukan proses kalsinasi. Dari hasil percobaan diperoleh bahwa metode gabungan kimia dan kalsinasi memiliki hasil desorpsi terbesar. Metode ini dapat mencapai desorpsi 29% uap air dari massa zeolit dengan metode HCL + 150oC. Untuk regenerasi sumber panas matahari dan sumber panas 150oC memiliki perbedaan hasil desorpsi ratarata 50 gram uap air dan 120 menit perbedaan waktu regenerasi. Setiap metode dapat mengembalikan kemampuan adsorpsi pada zeolit. ================================================================================ Adsorption refrigeration with zeolite as an adsorbent is an alternative cooling method. Zeolit is the mineral stone thatcan adsorp water vapour. Adsorption will stop when the zeolite pores full filled of water vapour. Zeolit can activated with regeneration process. Method of regeneration by calcination regeneration experiment solar heat source and heat source temperature 150oC with oven, combined chemical and calcination regeneration using NaOH liquid and HCL liquid to soak zeolites which are then carried calcination process. From the experimental results obtained that the combined chemical and calcination method has the largest desorption. It can desorp 29% of water vapour from mass of zeolite with HCL + 150oC method. For regeneration of the sun's heat source and a heat source 150oC has a difference of desorption results an average of 50 grams of water vapor and 120-minute time difference regeneration. Each method is able to restore the adsorption ability on zeolites.
