Eksperimental studi pada Fan Coil Unit (FCU) dilakukan untuk menginvestigasi karakteristik perpindahan panas akibat penambahan nanopartikel Al2O3. Tujuan penelitian ini adalah untuk mengungkap fenomena pengaruh nanofluid partikel pada indikator kinerja perpindahan panas. Pada penelitian ini digunakan FCU jenis tube and fin dengan fluida dingin adalah nanofluid Al2O3 dan fluida panas adalah udara. Laju aliran volume fluida dingin 15 lpm dan laju aliran massa fluida panas sebesar 0,48 kg/s. Konsentrasi nanopartikel yang digunakan pada penelitian ini adalah 0,1%. Temperatur udara lingkungan masuk FCU adalah 28±0,50C sedangkan temperatur fluida dingin yang memasuki FCU adalah 19±0,50C. Pada penelitian ini parameter kinerja pada fluida dingin dengan nanopartikel dibandingkan dengan tanpa nanopartikel. Hasil penelitian menunjukan pemakaian nanopartikel pada fluida dingin mampu meningkatkan perpindahan panas pada FCU sebesar 9,2%.
