Summary
The experiments on mass flow rate characteristics of R245fa refrigerant flowing through throttling devices including seven capillary tubes and the electronic expansion valve were carried out under the high-temperature working conditions. By combining regression analysis with flow correlations, the design basis that is applicable to R245fa throttling devices can be obtained. By comparing the experimental data with predicted data by Jung Correlation and Kim Correlation, it can be concluded that root mean square deviations of two correlations are 3.2 % and 3.3%, respectively. The root mean square deviation for electronic expansion valve is 4.5%. The conclusions offer highaccuracy design basis for throttling devices selection of high-temperature heat pump systems using R245fa as refrigerant.
