Abstract
The electrical substation building is one of the critical insfrastructure support components on the Well Head Central Processing Platform (WHCPP) for oil production. It is designed to give the comfort, safety, and optimal performance of electrical equipment. This research aims to ensure the comfort and safety provided to electrical equipment and operators through air conditioning system facilities that use environmentally friendly refrigeration systems with R-513A refrigerant, referencing the design standards of ISO 15138 and SOLAS. The method used is a qualitative with data collection,and then cooling load calculations refer to ASHRAE standards, taking into account both sensible and latent heat loads from internal and external sources. According to the results of the cooling load analysis, the refrigeration system is designed with an evaporator temperature of 7°C with a superheat output of 5°K, and a condenser temperature of 45°C with a sub-cooling output of 10°K, resulting in a mass flow rate of 3,000 kg/s, a condenser heat output of 543.594 kW, evaporator heat absorber of 471,666 kW, compressor power of 71,928 kW, and COP of 6.56. The HVAC system is designed for external air conditions with a maximum of 35.3°C DB and 33.1°C WB, entering air at 26.1°C DB and 19.4°C WB, leaving air at 12.6°C DB and 12.5°C WB, supply airflow of 17,742 L/s, return airflow of 15,866 L/s, and fresh air flow of 1,876 L/s. The design of mechanical and electrical of the refrigeration and HVAC sysemt is based on ISO 15138 and SOLAS standards. The results and conclusions of this research to obtain that the design parameters of the refrigeration and HVAC systems have been achieved in accordance with the ISO 15138 and SOLAS standards. Keywords: ISO 15138, SOLAS, Refrigerants, Environmentally Friendly, HVAC. Gedung teknis kelistrikan merupakan salah satu komponen penting dalam pendukung infrastruktur pada Well Head Central Processing Platform (WHCPP) produksi minyak yang dirancang untuk memberikan kenyamanan, keselamatan, dan kinerja optimal peralatan listrik. Penelitian ini bertujuan untuk memastikan kenyamanan dan keselamatan untuk peralatan listrik melalui fasilitas sistem tata udara yang menggunakan sistem refrigerasi ramah lingkungan R-513A, dengan mengacu pada standar perancangan desain ISO 15138 dan SOLAS. Metode yang digunakan adalah kualitatif dengan pengumpulan data, kemudian dilakukan perhitungan beban pendinginan mengacu pada standar ASHRAE dengan mempertimbangkan beban panas dan laten yang berasal dari faktor internal dan eksternal. Dari hasil perhitungan beban pendinginan diperoleh, sistem refrigerasi dirancang pada Tevaporator 7 oC dengan keluaran superheat 5 oK dan Tkondensor 45oC dengan keluaran cair sub-cooling 10oK didapat laju aliran massa 3,00 kg/s, kalor pembungan panas yang dikeluarkan oleh kondensor 543,594 kW, kalor yang diserap evaporator 471,666 kW, kerja kompressor yang dilakukan 71,928 kW dan COP mesin actual mesin refrigerasi 6.56. Sistem tata udara dirancang pada kondisi lingkungan udara luar maksimum 35.3 oC DB dan 33.1 oC WB, Tentering 26.1 oC DB dan 19.4 oC WB, Tleaving 12.6 oC DB dan 12.5 oC WB, jumlah aliran udara suplai 17742 L/s, aliran udara kembali 15866 L/s, dan aliran udara segar 1876 L/s. Perancangan mekanikal dan elektrikal sistem refrigerasi dan tata udara (HVAC) berdasarkan standar ISO 15138 dan SOLAS. Hasil dan kesimpulan dari penelitian ini mendapatkan bahwa parameter perancangan sistem refrigerasi dan tata udara tercapai sesuai standar ISO 15138 dan SOLAS. Kata kunci: ISO 15138, SOLAS, Refrigerant, Ramah Lingkungan, HVAC.
