STUDI KELAYAKAN BEBERAPA JENIS ZEOLIT ALAM SEBAGAI ADSORBENT PADA SISTEM REFRIGERASI ADSORPSI

Abstract

Adsorption cooling technology has several advantages compared to compression cooling, but in Indonesia, the application of asorption cooling technology is very still limited. This is because there were only a very limited amount of research had been done on this topic. The several objectives of this research were to study the appotunity of some local natural zeolites to be used as adsorbent in an adsorption cooling system and to discover the effect of zeolite type and size on adsorption capacity and adsorption rate. From the research, it can concluded that all of three type of zeolite studied were feasible to be used as adsorbent in an adsorption cooling system. At the time of optimal adsorpsion, value of adsorption capacity white zeolite reach 0,0334 H O gr / white zeolite gr, followed by harsh greenness of white zeolite ( 0,0261 H 2 O gr / harsh greenness of white zeolite gr), refinement greenness of white zeolite ( 0.022 H 2 O gr / refinement greenness of white zeolite gr), refinement black zeolite ( 0.0198 H 2 O gr / refinement black zeolite gr), and harsh black zeolite ( 0.0146 H 2 2 O gr / harsh black zeolite gr) by adsorpsion rate 1,114 gr / minute ( white zeolite), 0,871 gr / minute (harsh greenness of white zeolite), 0,734 gr / minute (refinement greenness of white zeolite), 0,659 gr / minute (refinement black zeolite), and 0,487 gr / minute ( harsh black zeolite). White zeolite can degrade temperature 601,449 gram irrigate equal to 1 o C, harsh greenness of white zeolite can degrade temperature 470,311gram irrigate equal to 1 C, refinement greenness of white zeolite can degrade temperature 396,107 gram irrigate equal to 1 o C, refinement black zeolite can degrade temperature 355,978 gram irrigate equal to 1 o C, and harsh black zeolite can degrade temperature 262,964 gram irrigate equal to 1 o C. At this research not yet been known the degradation rate of refrigeran temperature periodically, therefore need the existence of furthermore study in the form examination use Adsorption System refrigerator.
