Summary

On the basis of the analysis of each gas force in twin-scroll compressors, the calculation formulae of working volume and each gas force at all different crankshaft angles were derived. Comparing single-scroll compressors with twin-scroll compressors with the same displacement volume shows that the gas force of the latter is about 1.1- 1.5 times that of the former and the gas force fluctuation of twin-scroll compressors is about 1.3-1.5 times that of the former. The twin-scroll construction is more suitable for the needs of the large displacement volume. By the analysis of the geometrical relation between the integer cycle two spirals and the arbitrary cycle two spirals, the gas force models in the arbitrary cycle twin-scroll compressors were established.
