Abstract

Indonesia merupakan daerah yang beriklim tropis yang kadang pada saat musim panas manusia ingin kenyamanan, yaitu untuk menciptakan kondisi udara yang nyaman bagi orang yang berada di dalam suatu ruangan, disini yang diberi penyegar ruangan atau AC adalah ruang teknisi Balai Karya yang memiliki kapasitas ruangan sedang maka AC yang dipakai adalah AC Split. Dalam tugas akhir ini penulis akan merencanakan perhitungan beban AC Split tersebut. Beban kalor total pada AC (GTH) dihitung berdasarkan jumlah beban kalor sensibel dan jumlah beban kalor laten. Beban sensibel antara lain: beban kalor radiasi matahari melalui dinding, atap, langit-langit dan kaca, beban kalor yang ditimbulkan oleh lampu, beban kalor dari orang, dan beban kalor lainya yang berada didalam ruangan. Sedangkan beban kalor laten bersumber dari beban kalor orang dan infiltrasi. Proses perencanaan perhitungan beban AC Split dimulai dengan merencanakan suhu udara yang terkandung di dalam ruang teknisi balai karya (suhu ruangan diasumsikan 25 ), sedangkan suhu luar ruangan benar-benar diukur dengan menggunakan hygrometer didapat suhu sebesar - . Dari hasil perhitungan perencanaan beban AC didapat jumlah beban total (GTH) sebesar 20682,13 Btu/ hr dan temperatur udara suplai ( sebesar 14,5 ºF. Sehingga AC yang dipasang 1,5 PK. Dari hasil pengujian AC terpasang udara luar dan udara dalam diukur dengan menggunakan hygrometer. Didapat suhu dalam ruangan sebesar dan suhu luar ruangan sebesar , maka beban kalor total (GTH) didapat sebesar 16220.71 Btu/hr dan temperatur udara suplai ( sebesar 14,5 ºF. Indonesia is a tropical area that sometimes during the summer people want convenience, which is to create comfortable conditions for the air inside a room, here are given a room freshener or air conditioning technician Hall's work is a space that has room capacity is then AC used is AC Split. In this final duty the writer will plan for the Split air-conditioning load calculations. Total heat load on the AC (GTH) is calculated based on the amount of sensible heat load and the amount of latent heat load. Sensible load, among others: the burden of the solar radiation of heat through walls, roofs, ceilings and glass, heat load caused by lights, heat load of people, and other heat loads that are indoors. While the burden of latent heat derived from the heat load and infiltration. The planning process begins Split air conditioning load calculations by plotting the temperature of the air contained in chamber works technician hall (room temperature is assumed to be 25 ℃), while the outdoor temperature is actually measured using a hygrometer obtained temperatures of 32 ℃ - 33 ℃. From the results of AC load planning calculations obtained the number of total load (GTH) of 20682.13 Btu / hr and supply air temperature ( ) of 14.5 º F. So that the air conditioner installed PK 1.5. From the test results attached to the outside air and conditioned air is measured using a hygrometer. Obtained in a room temperature of 27 ℃ - 28 ℃ and outdoor temperature of 32 ℃ - 33 ℃, then the total heat load (GTH) obtained at 16220.71 Btu / hr and supply air temperature ( ) of 14.5 º F.
