Abstract
Most of the population in various parts of the world have felt the impact of the summer of 2023, breaking hot temperature records throughout the world. The global average temperature reached a new peak of 17.23° C. In the Jakarta area, the air temperature can reach 34 degrees Celsius with humidity reaching 60 %. One of the impacts experienced by workers, especially during the dry season, is feeling hot during the day. Studies show that the labor productivity of low-skilled workers decreases when air temperatures exceed a threshold of 26.2 degrees Celsius. In the SNI 03-6572-2001 guidelines which contain procedures for designing ventilation and air conditioning systems in buildings which explain the criteria for thermal comfort between an effective temperature of 20.5°C ~ 22.8°C and the speed of air falling overhead must not be more than greater than 0.25 m/sec. In this research, the author conducted research at the PT building. Jaya Kreasi Indonesia by collecting data in the work room on the Second Floor. The author's aim in this research is to calculate and analyze the cooling load which affects thermal comfort as well as simulating air distribution using the CFD method in the work space. Keywords : Thermal Comfort, Cooling Load, Air Distibution. Sebagian besar populasi di berbagai belahan dunia telah merasakan dampak musim panas tahun 2023 memecahkan rekor suhu panas di seluruh dunia.Suhu rata-rata global mencapai puncak baru 17,23° C. Di Wilayah Jakarta suhu udara bisa mencapai 34 derajat celcius dengan kelembaban mencapai 60%. Salah satu dampak yang dialami terutama para pekerja di musim kemarau adalah merasa gerah ketika siang hari. Studi menunjukkan bahwa produktivitas tenaga kerja pekerja berketerampilan rendah menurun saat suhu udara melampaui ambang batas 26,2 derajat Celcius. Pada pedoman SNI 03-6572-2001 yang memuat tata cara perancangan sistem ventilasi dan pengkondisian udara pada bangunan gedung yang menjelaskan kriteria kenyamanan termal antara temperatur efektif 20,5°C ~ 22,8°C serta kecepatan udara yang jatuh diatas kepala tidak boleh lebih besar dari 0,25 m/detik. Dalam penelitian ini, penulis melakukan penelitian pada gedung PT. Jaya Kreasi Indonesia dengan pengambilan data pada ruangan kerja pada Lantai Dua. Tujuan penulis pada penelitian ini untuk menghitung dan menganalisis beban pendingin yang mempengaruhi kenyamanan termal serta simulasi pendistribusian udara dengan metode CFD pada ruangan kerja tersebut. Kata Kunci : Kenyamanan Termal, Beban Pendingin, Distribusi Udara.
