Pembuatan Alat Penguji Kapasitas Adsorpsi pada Mesin Pendingin Adsorpsi dengan Menggunakan Adsorben Karbon Aktif

Abstract

Lately adsorption refrigeration cycle more and more scrutinized by experts as well as eco-friendly and economical use of renewable energy is solar energy. In order for the process of adsorption and desorption adsorption refrigeration cycle can run well to note that the ideal number of comparisons between the adsorbent with a refrigerant used. The data can be searched using the adsorption capacity tester. Adsorption capacity tester is used equipped with a 1000 W halogen lamp as a heat source. Adsorber on this tester is made of stainless steel which aims to resist corrosion due to the variation of refrigerant used. Activated carbon is used as adsorbent materials made from coconut shell base as much as 1 kg. While variations exist 4 refrigerant used is methanol, ethanol, ammonia and Musicool. Obtained the optimum refrigerant adsorption desorption process is methanol. Capacity that can be adsorbed methanol and desorption by activated carbon adsorbent is 275 mL.
