چکیده انگلیسی
In this paper, performance of a steam ejector designed based on the constant rate of momentum change (CRMC) and traditional ejector were tested in an attempt to compare its performance. Three different ejectors were designed and constructed; traditional ejector with throat diameter of 19 mm, traditional ejector with throat diameter of 13.4 mm, and CRMC ejector with throat diameter of 13.4 mm. They were designed to be easily equipped with the 1kW experimental ejector refrigerator. The boiler saturation pressure was varied from 130°C to 140°. The evaporator saturation temperature were fixed at 7.5°C. The result show that at the same operating condition and the same ejector area ratio (the area ratio of nozzle throat to ejector throat), CRMC ejector provided higher entrainment ratio than the traditional ejectors while the critical condenser pressure remain the same.
