On the basis of the analysis of each gas force in the 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 forces of the latter is about 1.1-1.5 times as large as those of the former and the gas forces fluctuation of twin - scroll compressors is about 1/3 -1/5 times as large as that of the former. The twin - scroll construction is more suitable for the request 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 forces models in the arbitrary cycle twin- scroll compressors were established.
