Abstract– The Objective of this research was to analyze effect of additionheat to electrical comsumption onAir Conditioner(AC). This research using a unit of split AC with capacity 9000 Btu/h and R22 refrigerant, set up on 4 x 4 meter room size. Condition of room experiment was varied by getting additionof heat from workers, electrical equipment and give some ventilation effect by opening the door every ½ and 1 hour.

The result of research showedthat by additionof cooling load in the room causing time required for conditioning thetestroomat 25° of temperature is longer, thus theelectrical energy consumed wasgreater. In theempty room, the timefor conditioning the test room at temperature up to 25oC is 1 ½ hours, with electrical energyconsumptionis 1.26kWh. The roomwith3 people workers, 1computer and1Laptop, the time required is2hours with electrical energy consumptionis 1.68kWh. The roomwith3 people workers, 1 computer, 1 laptop and the door was opened with 50% wide every½hour, the time required is3hours with electrical energyconsumptionis 2.54kWh. The roomwith3 people workers, 1 computer, 1 laptopandthe door was opened with 50% wide every1hour, the time required is2½hours with electrical energyconsumption is2.10kWh.

Keywords– Air Conditioner (AC), cooling load, electrical energy
