ON THE VALIDATY OF A DESIGN METHOD TO ESTIMATE THE SOLAR FRACTION FOR AN EJECTOR COOLING SYSTEM

摘要：

The present paper is concerned with the simulation of an ejector cooling system in order to investigate the validity of a design method to estimate the solar fraction. The cooling capacity of the ejector cycle is assumed to be constant during day periods. The ejector is assumed to steadily operate at its optimum efficiency point. The solar fraction derived from hourly simulation of the system is compared with estimates obtained by the chart f-φ- method based on the utilizability concept. An equivalent minimum temperature for the utilizability of the solar system is found, which is proved to be different but close to the vapor generator temperature of the ejector cycle.
