Experimental Determination of an Optimal Performance Map of a Steam Ejector Refrigeration System

An experimental determination of optimal performance a steam ejector refrigerator was proposed which aims to indicate the under various heat source temperatures. A small-scale test bench constructed carry out experiment and determine map. Three primary nozzles with throat diameters 1.4, 1.6, 1.8 mm, were tested an diameter 14.5 providing area ratios 107, 82, 65, respectively. For particular working condition, boiler temperature varied maximum COP is recognized as operation. It found that secondary fluid stream first choked at temperature. This point significantly evaporator temperature, condenser pressure, ratios. this could be operated between 102.5 117.5 °C depending on ratio, pressure. The map beneficial further control so achieved.
