Abstract

Proses Rancang Bangun Test Bed Cooling Tower Counter Flow bertujuan untuk mengetahui karakteristik cooling tower sebagai fungsi perubahan suhu beban melalui uji kelayakan dan simulasi kerja test bed cooling tower yang telah dirancang. Pada proses rancang bangun cooling tower ini dilakukan dengan beberapa pendekatan diantaranya termodinamika, perpindahan kalor dan mekanika fluida. Karakteristik menara pendingin dari data manual berupa range, approach dan beban kalor tentu tidak relevan dengan kondisi operasional saat ini. oleh karena itu dibutuhkan pengujiaan karakteristik menara pendingin sesuai dengan kondisi setempat. Penelitian dilakukan dengan menggunakan alat ukur thermometer, thermohygrometer, anemometer, dan Flowmeter pada menara pendingin. Hasil pengujian dengan menggunakan kapasitas 6 l/min sampai 11 l/min menunjukkan bahwa efektivitas menara berkisar 40,0 % s.d 46,51 % dengan rata-rata 44,42 %; cooling range 3,6 ̊C sampai 6 ̊C dengan rata-rata 4,92 ̊C; Approach berkisar 4,6 ºC sampai 7,8 ºC dengan rata-rata 6,15 ̊C. Perbandingan L/G 0,22 s.d 0,41 dengan rata-rata L/G 0,31 (kg air/ kg udara). Kata Kunci : Menara Pendingin, efektivitas, cooling range, approach, kapasitas pendinginan Design Process Test Bed Counter Flow Cooling Tower aims to investigate the characteristics of cooling tower as a function of load temperature changes through the due diligence and work simulation test bed cooling tower that has been designed. In the process of cooling tower design was done by several approaches including thermodynamics, heat transfer and fluid mechanics. The characteristics of the cooling tower in the form of manual data range, approach and the heat load is not necessarily relevant to the current operating conditions. therefore needed pengujiaan characteristics of cooling towers in accordance with local conditions. The study was conducted by using a thermometer measuring devices, thermohygrometer, anemometer, and Flowmeter in cooling towers. The test results by using a capacity of 6 l / min to 11 l / min showed that the effectiveness of the tower range 40.0% to 46.51% with an average of 44.42%; cooling range of 3.6 C to 6 C with an average of 4.92 C; Approach ranges from 4.6 º C to 7.8 º C with an average of 6,15 c. Comparison of L / G 0.22 sd 0.41 with an average L / G 0.31 (kg water / kg air). Keyword : Cooling Tower, Range, Approach, efectiveness, cooling capacity.
