Hydraulic designs of dishwashers with 12 (2 baskets) and 15 (3 baskets) place settings with diverter which distributes the water to bottom and upper spray arms separately were analyzed. First, both hydraulic systems were modeled analytically, so continuous and local losses were calculated based on them. Besides, operating point of systems were determined based on the curve of the pump and head loss. All parameters were also verified by experimental tests. An asynchronous circulation pump (fixed pump rpm and outlet pressure) with the same hydraulic outlet pressure is used in both products. Hydraulic design is evaluated with parameters obtained from the analytical model and then the design of equipment along the hydraulic path was improved. Once parameters improving the designs are determined, modified parts were analyzed numerically with finite volume method. The results were also validated with experimental studies. Lastly, prototype with improved design parameters was produced and installed on a dishwasher. Dishwasher performance index was calculated according to IEC standards to see the effect of new design on dishwasher washing performance. The results show that the energy requirement decreases 25% whereas performance index stays the same.
