Abstract

The use of split air conditioning (Split A/C) on residential applications, hotels and office buildings is currently the best solution to get more comfort when staying in a tropical country. The problem is Air Conditioner in a home or office building consumes 50% to 65% of the total electrical energy use in the home or office. For that problem, need innovations that can save the use of electrical energy while still getting the desired comfort. In this study was made a system that could utilize the work of Split A/C. This utilization produces cold water that can be used to cool the other room. The method is to change the construction of air conditioning by adding a shell and coil evaporator, so that the AC has a dual function as a mini water chiller. By doing this, it will certainly be able to save power consumption because to cool the room, the compressor as the largest power user does not need to be run all day, only used to cool the water. The results of the study are mini water chiller system has COPactual of 5.37. COPcarnot of 6.75 and refrigeration efficiency of 79.3%, the electricity consumed by Split A/C (direct expansion) for two hours of usage is 0,83816 kWh while the electricity consumed by the mini water chiller system is 0,25466 kWh in the same period or this system is 69% more efficient than the direct expansion system.
