Studi Eksperimen Variasi Laju Pendinginan Kondensor pada Mesin Pendingin Difusi Absorpsi R22-DMF

Abstract

Teknologi pendinginan lama yang mulai digunakan salah satunya adalah mesin pendingin Difusi Absorpsi COP dari mesin pendingin difusi absorpsi banyak dipengaruhi dari  desain generator. Pada penelitian ini eksperimen dilakukan dengan mendesain ulang generator pada mesin pendingin difusi absorpsi yang menggunakan pasangan refrigeran R22-DMF serta penambahan fan di kondensor. Metode dalam penelitian ini adalah pengambilan data dilakukan dengan empat variasi laju pendinginan pada kondensor. Hasil yang diperoleh dari pengujian untuk variasi laju pendinginan dari 0,711 m/s hingga 2,291 m/s yaitu semakin tinggi laju pendinginan maka semakin baik performa pada sistem. Kapasitas pendinginan optimal ialah 143 W, COP tertinggi 0,96, laju alir massa refrigeran terbesar ialah 0,72 gram/s, dan circulation ratio terendah yaitu 2,11.
