Abstract

Penelitian ini membahas bagaimana pengaruh modifikasi ducting HVAC pada tiap-tiap kompartemen di dalam badan tekan submersible vehicle. Dimana kondisi simulasi dijalankan pada mode snorkel dengan mesin disel yang beroperasi pada keadaan beban penuh. Hasil dari simulasi akan dianalisis untuk mengetahui seberapa besar pengaruh modifikasi memberikan perubahan pada kondisi udara badan tekan kapal. Variabel yang dianalisis dalam simulasi ini diantaranya adalah perubahan suhu udara, perubahan tekanan udara, dan perubahan kecepatan aliran udara pada tiap kompartemen. Ruang-ruang yang dianalisis dan disimulasikan diantaranya adalah ruang baterai A, ruang baterai B, ruang permesinan, ruang mesin bantu, ruang operator 1, ruang operator 2, dan ruang operator 3. Simulasi dilakukan dengan menggunkan metode computational fluid dynamics (CFD) pada software SimScale. Data pada penilitan ini diambil melalui dokumen yang tersedia dan pengambilan data langsung atau survei. Berdasarkan hasil simulasi yang sudah dilakukan didapatkan perubahan suhu ruangan pada ruang baterai A sebanyak 3,62%; pada ruang baterai B sebanyak 5,38%; ruang mesin bantu sebanyak 2,46%; ruang operator 1 sebanyak -4,28%; pada ruang operator 2 sebanyak -3,30%; pada ruang operator 3 sebanyak -7,92%; pada ruang permesinan sebanyak -3,13%. Sedangkan untuk perubahan tekanan udara pada ruang baterai A -0,001%; pada ruang baterai B -0,338%; pada ruang mesin bantu -0,402%; pada ruang operator 1 5,470%; pada ruang operator 2 5,479%; pada ruang operator 3 5,467%; dan ruang permesinan sebanyak 0,306%. Perubahan kecepatan aliran udara pada ruang baterai A 38,47%; pada ruang baterai B -1,30%; pada ruang mesin bantu -0,41%; pada ruang operator 1 39,80%; pada ruang operator 2 63,54%; ruang operator 3 87,10% dan ruang permesinan 0,55%.

This study discusses the effect of HVAC ducting modifications on each compartment in the submersible vehicle pressure hull. Where simulation conditions are run in snorkel mode with diesel engines operating at full load. The results of the simulation will be analyzed to determine how much influence the modification has on the air condition of the ship's compressive body. The variables analyzed in this simulation include changes in air temperature, changes in air pressure, and changes in air flow velocity in each compartment. The spaces analyzed and simulated include battery room A, battery room B, engine room, auxiliary engine room, operator 1 room, operator 2 room, and operator 3 room. The simulation was conducted using the computational fluid dynamics (CFD) method on SimScale software. The data in this research is taken through available documents and direct data collection or surveys. Based on the simulation results, it is found that the room temperature change in battery room A is 3.62%; in battery room B is 5.38%; in auxiliary engine room is 2.46%; in operator 1 room is -4.28%; in operator 2 room is -3.30%; in operator 3 room is -7.92%; in engine room is -3.13%. As for the change in air pressure in battery room A -0.001%; in battery room B -0.338%; in the auxiliary engine room -0.402%; in the operator 1 room 5.470%; in the operator 2 room 5.479%; in the operator 3 room 5.467%; and the engine room as much as 0.306%. Change in airflow velocity in battery room A 38.47%; in battery room B -1.30%; in auxiliary engine room -0.41%; in operator 1 room 39.80%; in operator 2 room 63.54%; operator 3 room 87.10% and engine room 0.55%.
