Abstract

Sistem HVAC pada submersible vehicle memiliki fungsi sebagai pengatur suhu, penjaga kelembaban, sirkulasi udara, suplai udara ke pembakaran mesin dan pengendali tekanan. Optimalisasi sitem HVAC ini perlu dilakukan dalam rangka meningkatkan efisiensi energi, meningkatkan kenyamanan dan kesehatan awak kapal serta menjaga kinerja peralatan yang ada di submersible vehicle. Untuk mengoptimalkan sistem HVAC yang ada, maka perlu dilakukan adanya modifikasi penambahan flaps pada snorkel tank di submersible vehicle. Modifikasi ini perlu disimulasikan untuk mendapatkan gambaran terkait pengaruh modifikasi ke dalam sistem HVAC yang sudah ada. Simulasi CFD (Computational Fluid Dynamics) yang digunakan dalam penelitian ini bertujuan untuk mengetahui perubahan variabel tekanan, kelembaban, kecepatan dan suhu udara pada ruang – ruang di submersible vehicle akibat dari modifikasi penambahan flaps pada snorkel tank. Hasil simulasi menunjukkan bahwa perbedaan suhu dalam submersible vehicle terjadi dari rentang 0,99% hingga 4,77%, perbedaan tekanan terjadi dari rentang 0,15% hingga 1,71%, perbedaan kelembaban terjadi dari rentang 0,02% hingga 12,29%. Analisis ini menunjukkan bahwa modifikasi memiliki pengaruh yang bervariasi pada setiap parameter lingkungan di tiap ruangan. Ruang Baterai A mengalami peningkatan terbesar dalam kecepatan aliran udara, Ruang Baterai B mengalami perubahan terbesar dalam suhu dan kelembaban, serta Ruang Operasi 1 dan Ruang Operasi 2 mengalami penurunan terbesar dalam tekanan rata-rata.

The HVAC system on a submersible vehicle functions as a temperature regulator, humidity controller, air circulator, air supply for engine combustion, and pressure controller. Optimizing this HVAC system is necessary to improve energy efficiency, enhance the comfort and health of the crew, and maintain the performance of the equipment in the submersible vehicle. To optimize the existing HVAC system, modifications by adding flaps to the snorkel tank in the submersible vehicle are needed. This modification must be simulated to understand its impact on the existing HVAC system. The CFD (Computational Fluid Dynamics) simulation used in this study aims to determine the changes in variables such as pressure, humidity, air velocity, and temperature in the compartments of the submersible vehicle due to the modification of adding flaps to the snorkel tank. The simulation results show that temperature differences in the submersible vehicle range from 0.99% to 4.77%, pressure differences range from 0.15% to 1.71%, and humidity differences range from 0.02% to 12.29%. This analysis indicates that the modification has varying impacts on each environmental parameter in each room. The Battery Room A had the greatest increase in airflow velocity, The Battery Room B had the greatest change in temperature and humidity, and the Operating Room 1 and Operating Room 2 had the largest decrease in average pressure.
