Energy conversion system based on thermoelectric generator that utilized the residual heat of condenser as heat energy resource and water circulation as a cooling system has been designed. Thermoelectric generator functions as a heat-to-electricity energy conversion by using temperature difference between the two sides of the thermoelectric 4 x 4 x 0.3 cm TEG SP1848 module has been used as a thermoelectric generator that can hold back the temperature up to 125°C. The conductance value of TEG SP1848 is 0.0025 W/K. The important part of energy conversion systems are thermoelectric generator configuration, conductor and cooling system. Conductor is the component which functions as heat transfer media from condenser pipe to thermoelectric generator. The diameter of the condenser pipe in this study was 4.2 cm. The function of cooling system is cooling up the thermoelectric generator cold side in order to enhance the temperature difference between cold side and hot side. The cooling system that used in this research is water cooling that consisting of a water pump, water block, radiator, fan and water. The collecting data has been done by using series configuration of thermoelectric generator and varying the temperature of 40°C -110°C and the resistance of 10Ω-200Ω. The best resistance that can produce the greatest power is 39 Ω. The hot side temperature that can produce the greatest power in this study is 110 °C. The average of power and efficiency of energy conversion system was 0.129 W and 2%.
