Abstract

Penelitian ini bertujuan untuk mengetahui (1) Performa AC split wall mounted yang terpasang di kamar mesin lift Gedung Raden Ajeng Kartini Universitas Negeri Jakarta, (2) Beban pendinginan kamar mesin lift di Gedung Raden Ajeng Kartini Universitas Negeri Jakarta. Metode yang digunakan dalam penelitian ini yaitu analisis deskriptif dengan pendekatan kuantitatif berdasarkan data-data hasil pengukuran koefisien prestasi (COP) untuk performa AC dan beban pendinginan (cooling load) yaitu beban dalam dan beban luar. Teknik analisis data yang digunakan adalah dengan cara analisis statistik, yaitu peneliti membandingkan data yang dihasilkan dengan standar yang berlaku. Hasil penelitian menunjukkan bahwa (1) Hasil perhitungan COP pada jam 09.00 sebesar 1,79, jam 12.00 sebesar 1,72 dan jam 15.00 sebesar 1,78 tidak memenuhi standar katalog AC Daikin sebesar 3,15 dan standar SNI-93-6390-2000 sebesar 3,15. (2) Hasil perhitungan EER pada jam 09.00 sebesar 0,525, jam 12.00 sebesar 0,504 dan jam 15.00 sebesar 0,522 tidak memenuhi kriteria hemat energi suatu mesin pendingin berdasarkan Peraturan Menteri ESDM Nomor 57 Tahun 2017, kriteria hemat energi terendah atau bintang satu berada di angka 8,53 ≤ EER ≤ 9,01. Untuk meningkatkan performa AC split tersebut dapat dilakukan pengecekan kondisi tiap-tiap komponen, perawatan dan pembersihan AC split. (2) Hasil perhitungan beban pendinginan di kamar mesin lift sebesar 24032,51 BTU/jam, AC split yang terpasang saat ini tidak dapat memenuhi beban pendinginan tersebut karena hanya terpasang satu buah dengan kapasitas 2 PK yaitu 18000 BTU, maka jumlah AC split yang dapat digunakan untuk menanggung beban tersebut sebanyak dua unit dengan kapasitas masing-masing unit sebesar 2 PK yaitu 18000 BTU. This study aims to determine (1) the performance of AC split wall mounted installed in the elevator engine room of the Raden Ajeng Kartini Building, State University of Jakarta, (2) the cooling load of the elevator engine room in the Raden Ajeng Kartini Building, State University of Jakarta. The method used in this research is descriptive analysis with a quantitative approach based on the data from the measurement of the coefficient of achievement (COP) for AC performance and cooling loads, namely internal loads and external loads . The data analysis technique used is statistical analysis, where the researcher compares the resulting data with applicable standards. The results showed that (1) The calculation result of COP at 09.00 is 1.79, at 12.00 is 1.72 and at 15.00 is 1.78, it does not meet the AC Daikin catalog standard of 3.15 and SNI-93-6390-2000 standard of 3.15 . (2) The results of the calculation of EER at 09.00 am 0.525, 12.00 am 0.504 and 15.00 am 0.522 do not meet the energy saving criteria of a cooling machine based on the Minister of Energy and Mineral Resources Regulation Number 57 of 2017, the lowest energy saving criteria or one star is at number 8, 53 EER 9.01. To improve the performance of the split AC, it is possible to check the condition of each component, maintain and clean the split AC. (2) The calculation result of the cooling load in the elevator engine room is 24032.51 BTU/hour, the currently installed split AC cannot meet the cooling load because only one unit is installed with a capacity of 2 PK which is 18000 BTU, then the number of split ACs that can be installed used to bear the load as many as two units with a capacity of each unit of 2 PK which is 18000 BTU.
