Abstract

In this era of modernization, air conditioning systems are very important in everyday life in providing comfort and good air flow to users in a room. Lack of knowledge about the use of this air conditioning system can result in consumers losing money when the energy used by the system is excessive. The purpose of this project is to measure the power consumption of air conditioning system from six AHU room and analyze the energy consumption by air conditioning systems in the Faculty of Engineering Technology (FTK) building. There are several factors that lead to increased energy usage in the air conditioning system. These include high outdoor temperatures, occupancy activities and electrical appliances that also contribute to the increase in heat in this building. Based on the layout of this building, there are six air handling unit (AHU) units and 35 fan coil unit (FCU) units used to supply air to whole building. The experiment was carried out in six different areas namely the left and right areas of the FTK building for three different floors where the data will be taken at the main switch inside the distribution box (DB) which located inside the ahu room by using FLUKE 435 series-ll. This assessment is conducted to quantify the energy use by air conditioning systems for three different levels. Data collection will be done using equipment that can detect energy consumption, namely energy quality analyzer. This energy evaluation project will be conducted at the FTK building from 9 am to 5 pm on weekdays. As the result, the data of energy consumption recorded by three different level shows that the highest energy consumption is by level 2 which is 104.56 Kwh followed by ground floor level 104.40 Kwh and level 2 85.60 Kwh. The result is mostly affected by the occupant activities at the floor.
