Abstract
A computer program designed to optimize the size of an evaporative condenser in a two-stage industrial refrigeration plant was created. The program sizes both the high-stage and low-stage compressors and an evaporative condenser. Once the initial system is sized, a year long plant simulation is performed resulting in electric energy consumption profile and an exergy destruction profile for each component and for the system. The program uses actual regional hourly outside dry bulb and wet bulb temperatures for both sizing and simulation. An exergoeconomic optimization uses the results of the simulation combined with component and energy costs to optimize the condenser size such that both plant costs and energy losses are minimized.
