Summary

In recent years, the requirement of energy efficiency for refrigeration and air condition systems becomes more and more higher while the cost needs to be more and more lower, at the same time some new applications of refrigeration and air condition systems are emerging rapidly. All of these demands need a new compressor to meet.
In this paper, a new dual-cylinder rolling piston compressor with two independent suction ports and two independent discharge ports was proposed. The structure and working principal of this compressor were described, and the performance was tested. Then simulation model was built to research the performance of the system using this kind of compressor compared with the traditional system. Simulation results showed that the COP of the system using this kind of compressor is 0.5%~4.4% higher than that of the traditional system in cooling condition, and 2.1%~3.9% higher than that of the traditional system in the heating condition.
