Evaluation of a Steam Jet Refrigerator with the Varying Specific Heat Ratio

Abstract:

To predict the working performance of the jet refrigeration system more precisely, including the condensing temperature and coefficients of performance, this paper presents a 1-D analysis model with the varying specific heat ratio. During the evaluation, the working process of the constant pressure ejector is divided into three sections with different specific heat ratios. By comparing the results from Eames experiment, the simulation results indicate that this model is more reasonable, and the error of the simulation is within 20%, which is significantly smaller than the error of Eames model at 40%.
