The use of energy in the world is increasing every year, and the higher the use of energy, the more waste heat is not utilized properly by the industry. The ORC generating system is a system that can utilize the waste heat well because of the character of the ORC system itself. There are several important components that make up the ORC system to work properly, two of them are evaporators and condensers. It is very important to design a good evaporator and condenser so that the ORC system works well. It will be simulated to find out the main dimensions of the evaporator and condenser and to estimate evaporator and condenser performance. <br /> <br /> <br /> <br /> After determining the working operation, using simulations on the HTRI software, there are 3 diameters used as simulated diameters, 19.05 mm, 22.23 mm and 25.4 mm. The simulated types are AGL, AHL, AJL and AXL in the condenser and AGL, AHL, AJL, and AKT on the evaporator. Then the fluid velocity on the tube will be calculated to ensure that the velocity is still within the permissible limits. After that, the thermal aspects and pressure drop on the shell side will be taken as the main parameters for determining the type of shell & tube. The termal aspect will be reviewed in the form of overdesign from the evaporator and condenser <br /> <br /> <br /> <br /> The best performing of evaporator type is AKT type with an outer diameter of 25,4 mm with pressure losses of 0,639 kPa, overdesign of 1,56% and the area of heat transfer is 61,74 m2. In the condenser, the type that has the best performance is the AHL type with an outer diameter of 25.4 mm, with pressure drop of 2,0 kPa, overdesign 0,3%, and the area of heat transfer is 120,7 m2.
