Abstract


ABSTRAK

Penelitian ini bertujuan untuk melihat hubungan kondisi udara masuk terhadap kondisi udara keluaran air cooler. Selain itu juga untuk mendapatkan nilai efektivitas rata rata air cooler. Suhu udara masuk divariasikan, tetapi memiliki kelembapan spesifik w yang sama. Proses penurunan suhu udara, terjadi pada saat udara melewati beberapa cooling padyang permukaannya dialiri air. Proses pendinginan udara diasumsikan berjalan secara evaporative cooling. Penelitian dilakukan secara eksperimen, dengan mempergunakan air coolerbuatan sendiri. Untuk suhu udara masuk berturut turut: 30oC, 35oC, 40oC dan 45oC, dihasilkan suhu udara keluaran berturut turut sebesar 26,27oC, 27,66oC, 29,10oC, 30,9oC dengan efektivitas rata rata air cooler89,5%.

ABSTRACT

This study aims to see the relationship between the intake air conditions and the air cooler outlet air conditions. In addition, to get the value of the effectiveness of the air cooler. The intake air temperature is varied, but has the same specific humidity W. The process of decreasing the air temperature occurs when the air passes through several cooling pads whose surface is flooded with water. The air cooling process is assumed to run by evaporative cooling. The research was conducted experimentally, using a homemade air cooler. For the inlet air temperature in a row: 30oC, 35oC, 40oC and 45oC, the resulting output air temperature is 26,27oC, 27,66oC, 29,10oC, 30,9oCwith the average effectiveness of the air cooler 89,5%.
