EVALUATION OF A COMBINED EJECTOR-VAPOR-COMPRESSION REFRIGERATION SYSTEM

A new refrigeration cycle based on the combination of an ejector cycle with a vapour compression cycle is described. This integration maximi zes the performance of the conventional ejector cycles and provides hi gh COP for refrigeration. The analyses show that the new cycle has a s ignificant increase in system performance over the conventional system s, its COP values are competitive to the absorption machines. If the s ystem is powered by waste heat and the cost of its supply can be negle cted, the COP values will be much higher. The system performance can b e further improved if dual refrigerants are used and the dual refriger ants giving high performance are identified. (C) 1998 John Wiley & Son s, Ltd.
