PERENCANAAN DAN PEMASANGAN AIR CONDITIONING PADA RUANG DOSEN DAN TEKNISI PSD III TEKNIK MESIN UNIVERSITAS DIPONEGORO SEMARANG

Abstract

PLANNING AND INSTALLATION OF AIR CONDITIONING IN THE TEACHING AND TECHNICIANS ROOM PSD III MECHANICAL ENGINEERING DIPONEGORO UNIVERSITY SEMARANG Air Conditioning is an equipment used to condition the air so as to achieve the temperature and humidity in accordance with the comfortable air condition under the rules K3. Working to provide comfort for people doing certain activities inside the room. In this final project room cooling load calculation. Cooling loads are planned based on several factors, namely sensible heat and latent heat factor. The HVAC system is planned in the form of units of Air Conditioning Split. To get the air to the desired conditions, the equipment installed must have the capacity in accordance with the cooling load in the room. It required surveys and calculations to determine the cooling load. Based on design power calculation 24°C temperature and humidity (RH) 50% obtained the cooling load of 10.836,94 Btu/hr. So that in the dosen and technicians room use a unit Air Conditioning with a 12,000 Btu / hr cooling capacity. From the results test are known power load refrigerant decreases when approaching the specified temperature and humidity. Key Word = Air Conditioner, Cooling Load, Temperature, Humidity.
