Abstract

Telah dilakukan modifikasi simulator cooling tower dari tugas akhir sebelumnya. Modifikasi dilakukan guna memaksimalkan kinerja simulator cooling tower. Cooling tower adalah suatu sistem refrigerasi yang melepaskan kalor ke udara. Pengendalian temperature pada proses pendinginan menggunakan variable speed drive yang sudah di couple dengan motor servo pada potensiometer internalnya. Dengan begitu kecepatan putar pada fan akan menyesuaikan dari nilai temperature fluida. RTD sebagai sensor temperature, ATmega16 sebagai controller, dan solenoid valve untuk menjaga temperature pada keluaran agar terjaga sesuai set point yaitu 28°C. Sensor RTD PT100 3 wire memiliki nilai error sebesar 0.86% dan nilai akurasi sebesar 98.97%. Variable speed drive memiliki nilai error sebesar 1.4% dan nilai akurasi sebesar 98.99%. Respon sistem dengan nilai maximum overshot sebesar 4% dengan rise time pada menit ke 17 dan settling time pada menit ke 21 dimana jika dibandingkan dengan menurunkan temperature tanpa menggunakan fan, didapatkan selisih waktu selama 46 menit.

Cooling tower simulation has been done from the previous final project. Modifications were made to maximize the performance of the simulator cooling tower. Cooling tower is a cooling system that releases heat into the air. Temperature control during the process uses a variable speed drive that has been installed with a servo motor on its internal potentiometer. With a fast rotating speed on the fan will adjust the value of the fluid temperature. RTD as a temperature sensor, ATmega16 as a controller, and a solenoid valve to maintain the temperature to fit 28 ° C. The PT100 3 wire RTD sensor has an error value of 0.86% and a verification value of 98.97%. The variable speed drive has an error value of 1.4% and an accuracy value of 98.99%. The response system with a maximum overshot value of 4% with an increase time in the 17 minute and a completion time in the 21 minute which when compared with a decrease in temperature without using a fan, the time difference for 46 minutes.
