Description

We conducted numerical and experimental analysis to improve the efficiency of dual-cylinder rolling piston type rotary compressors by varying cylinder height H, diameter D and eccentricity E by developing a simulator for obtaining the optimum combination of the cylinder dimensions. As a result, the lower ratio of cylinder height to diameter tends toward higher efficiency. The experimental results correspond to the numerical analysis.<br>This investigation includes the reduction of superheat loss during the suction process of a compressor with a thermally isolated cylinder and the acquirement of optimum design conditions for an eccentric bearing. The numerical and experimental results show that a thermally isolated cylinder and an eccentric bearing with optimum design are effective for high efficiency.<br>The results show that the total efficiency of a 3/4 ton prototype dual-cylinder rotary compressor with these effective improvements is higher than that of a conventional single-cylinder type with equivalent capacity.
