Abstract

Increasing the efficiency is one of methods to assist the Indonesian government’s planning in saving energy. One of them is to combine two functions from two different devices become a new device that have two functions. For instance, Split AC is used to cool the room. The adding of dummy condenser in Split AC is using heat exhaust at condenser that functioned as water heater. In this research, it is aimed to identify the effect of adding the dummy condenser toward cooler load. The method used in this research was design and experimental method. Based on the test, When cooler load was given to the room, the more the burden of cooling given, the higher refrigerant temperature to be thus heat water temperature was higher as well. During the operation 120 minutes, it obtained that heat water temperature was 84,110C and refrigerant temperature was 64,770C.Keywords : Dummy Condenser, Temperature, Cooler load and water valve faucet.

Abstract

Air conditioning machines are generally used to provide a cooling effect. The cooling effect is intended to provide comfortable zone in a cooled room, so that a sense of comfort makes people feel at home in it. Most air conditioning machines operate thermodynamically using a vapor compression cycle, where heat is absorbed inside of the evaporator in the room, then this heat is discharged in an outdoor condenser. This process can take place because of the compressor's work and the pressure drop that occurs in the expansion valve or capillary pipe, so that the vapor compression cycle works perfectly. In air conditioning systems usually heat is wasted useless, the heat can be used to heat water with the addition of a dummy condenser. The addition of a dummy condenser in this study was conducted to see the effect of adding a dummy condenser to cooling load, compression power, temperature, and the Coefficient of Performance (COP). The method used in this study is the design and experimental methods. Based on the results of the test, during the 120 minute operation the hot water temperature achieved at no load conditions (0W), 1000W, 2000W and 3000W loads are 52.83oC, 56.58oC, 57.93oC and 64.73oC, respectively.
