Loss analysis of scroll expanders using R134a refrigerant was investigated and the following results were obtained. A loss estimating method of scroll expanders was proposed by using indicated power calculated by measured P-V diagram and another values. Leakage gas loss in suction process was large, so tip seals of scroll clearance are very important to realize high efficient scroll expanders. A new suction port system was designed and by this new type scroll expanders gas leakage decreased about 10% and expander efficiency increased about 10%.
