Abstract

Penelitian ini melakukan investigasi tentang optimasi sitem pendingin menggunakan Thermal Energy Storage pada gedung komersial. Penggunaan sistem pendingin di gedung komersial mencapai 50 % dari total konsumsi energi gedung. Pemerintah Indonesia menetapkan biaya penggunaan listrik yang mahal untuk gedung komersial. Perusahaan Listrik Negara menetapkan harga waktu beban puncak mencapai dua kali luar waktu beban puncak. TES merupakan solusi alternatif, yang menggeser beban listrik selama waktu beban puncak yang tarifnya mencapai dua kali periode luar waktu beban puncak. Dalam hal ini, chiller menghasilkan air dingin (chilled water) untuk mencapai beban pendinginan yang diperlukan dan disimpan ke dalam TES tank. TES tank akan mengurangi rentang operasi kapasitas total chiller. Namun heat loss pada TES tank harus di pertimbangkan karena heat loss yang lebih besar akan menyebabkan kapasitas total chiller dan biaya investasi pada setiap gedung dan kombinasi antar gedung komersial akan semakin besar. Dalam penelitian ini, terdapat 11 kombinasi gedung komersial yang akan diterapkan dalam beberapa variabel optimasi. Penelitian ini melakukan optimasi kapasitas total chiller, beban pendinginan gedung dan heat loss yang minimum dengan menggunakan simplex linier programming. Hasil penelitian menunjukkan bahwa penghematan rata rata gedung komersial mencapai 19,6 %. =============================================================================================== The cooling system optimization using Thermal Energy Storage (TES) in commercial buildings is investigated in this research. The use of cooling systems in commercial buildings is up to 50% of total energy consumption. This consumes expensive electricity cost according to electricity tariffs determined by Indonesian Government. Indonesian state electricity company set prices peak load up to twice the price outside peak hours. TES is an alternative solution, shifting the use of electrical load during the peak period which the tariff is twice as the off peak period. In this case, chiller produces cold water to achive the required cooling load and save to the TES tank. The TES tank will reduce the chiller total capacity operating range. However heat loss at the TES tank has to be considered because greater heat loss will required additional total chiller capacity and investment costs at each buildings and their combination. In this research, as 11th combination of commercial buildings, which applied optimization on several compenting variables. The optimization is minimizing the combined of total chiller capacity, cooling load of the building and heat loss using simplex linier programming. The results shows that 19.6% savings of the average of commercial buildings.
