V KESIMPULAN DAN SARAN
5.1 Kesimpulan
1. Model simulasi CFD dinyatakan berhasil dengan baik untuk memprediksi
suhu udara nilai CV sebesar 0.12 dan CU sebesar 89.76. dan pola aliran udara, sehingga rumah tanaman tipe modified arch memiliki kinerja yang
baik. 2.
Hasil simulasi distribusi suhu menunjukkan hasil yang seragam, dengan pola aliran udara terjadi dari inlet bukaan dinding menuju outlet bukaan atap.
3. Perbedaan suhu udara di dalam rumah tanaman tipe modified arch dengan
suhu lingkungan berkisar antara 2.2 - 5.5
o
C. Gradien suhu terjadi secara vertikal, tetapi besarnya tidak signifikan.
4. Distribusi suhu dan pola aliran udara dalam rumah tanaman dengan ventilasi
alami mampu dijelaskan dengan baik menggunakan program CFD dan memungkinkan dilakukan permodelan untuk memprediksi suhu dan
kelembaban udara di dalamnya. 5.
Ventilasi alamiah dalam rumah tanaman tipe modified arch bekerja secara efektif baik terjadi dengan adanya pengaruh kecepatan angin maupun tanpa
adanya kecepatan angin di luar rumah tanaman karena saat angin tidak bertiup maupun saat kecepatan angin rendah pertukaran udara tetap terjadi karena
adanya chimney effect.
5.2 Saran
Perlu dilakukan pengembangan model simulasi dengan pendefinisian sistem yang lebih baik diantaranya dengan menambahkan beberapa parameter bahan
screen seperti koefisien discharge dan nilai permeabilitas bahan screen agar
menghasilkan output simulasi yang lebih baik.
