Abstract

This research presents two helical capillary tube sizing charts for R407C and R410A, two correction charts for another tube size, and a correction chart for all mixture ratios of R125, R134a and R32. These charts are obtained from the homogeneous flow model including the effect of gravitational force. It is verified by comparison with experimental data obtained from the published literature. From the model, the sizing charts for a diameter of 1.63[Formula: see text]mm, length of 2.03[Formula: see text]m, and helix diameter of 500[Formula: see text]mm are developed. Two charts for size correction are also developed. The first one is for tube diameter of 0.5–5[Formula: see text]mm and length of 0.25–10[Formula: see text]m. The second one is for helix diameter of 20–1000[Formula: see text]mm. Finally, one more chart for mixture ratio correction is proposed. This chart can be applied to all mixture ratios of R125, R134a and R32.
