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.
