Abstract

Institut Teknologi Kalimantan (ITK) merupakan salah satu perguruan tinggi negeri baru yang berlokasi di tengah hutan di Balikpapan. Berdasarkan data Badan Meteorologi, Klimatologi dan Geofisika, kecepatan angin rata-rata di sekitar ITK berkisar antara 5 km/h ? 18 km/h. Potensi angin yang melimpah dapat dimanfaatkan untuk merancang turbin angin yang sesuai yaitu turbin angin tipe horizontal.  Perancangan turbin angin sumbu horizontal dengan tiga sudu dilakukan dengan variasi besar sudut serang untuk menentukan tingkat efisiensi turbin angin. Variasi besar sudut serang adalah 50, 100, dan 250. Pengujian turbin angin dilakukan pada beberapa tingkat kecepatan angin diantaranya 3.8 m/s, 4.3 m/s, 5.8 m/s. Hasil pengujian menunjukkan bahwa daya listrik terbesar dihasilkan pada pengujian turbin angin sumbu horizontal dengan variasi sudut serang 250 yaitu sebesar 118.7 mW.

Abstract

E-201-11 is one of the components of heat exchanger which serves to increase the temperature of distillated crude oil before it going into the furnace. The use of segmental baffles on the heat exchanger causes dead zone. The fouling phenomenon that arises from the deposition of the compound content in the service fluid in dead zone can result in leakage of the shell and tube. It affects the performance of heat exchanger and production efficiency. The use of discontinuous helical baffle on the shell side minimizes fouling. Research on the variation of helical baffle angle by using Bell-Delaware method resulted in performance value of heat transfer coefficient and pressure drop on the shell side. Fluid flow behavior on the shell side with helical baffle was analyzed by Computational Fluid Dynamics (CFD). The fluid flow velocity is a factor that affects the value of heat transfer coefficient and pressure drop. Heat exchanger with an angle of 10º have fluid flow velocity of 0,893m/s resulting in the highest heat transfer coefficient and pressure drop value compared to angles of 15º and 20º with values of 585.725W/m²K and 13642.395Pa. The heat exchanger with helical baffle at 10° helix angle presents the best performance among the others variant helical baffles

The use of segmental baffles on the heat exchanger causes dead zone. The fouling phenomenon that arises from the deposition of the compound content in the service fluid in dead zone can result in leakage of the shell and tube. It affects the performance of heat exchanger and production efficiency. The use of discontinuous helical baffle on the shell side minimizes fouling. Research on the variation of helical baffle angle by using Bell-Delaware method resulted in performance value of heat transfer coefficient and pressure drop on the shell side.

Abstract

The era of globalization requires humans to continue to innovate in developing technology. The comfort factors of a room are largely determined by the location, characteristics and activities in it. Determination of the amount of power in the Air Conditioner is carried out based on the amount of cooling load obtained. The method used is data the collection of the outside temperature, the measurement of the area of the component to be calculated, and the heat transfer coefficient for the components used. The results show that the cooling load in the 104F lecture room of 21,133 Watt of equivalent to 72,109 BTU/h. While the cooling load in the 105F lecture room, the results are 13,444 W or equivalent to 45,873 BTU/h. From that finding, it can be concluded that the power of the Air Conditioner used in the two rooms has not covered the amount of existing cooling, because the 104F lecture room has three Air Conditioners whereas one Air Conditioner has a power of 2 PK or equivalent to ±18,000 BTU/h, and 105F have two Air Conditioners with the same power. So that the cooling load of the two rooms is greater than the power of the Air Conditioner used.
