Summary

In this paper, thermophysical properties of CO2 were introduced and a transcritical theory cycle was analyzed. On the base of analyzing theory cycle, other cycles with regenerator or expander or both regenerator and expander was in detail researched. By comparing the COP of each cycle, it was found that the COP is maximal when discharge pressure is an optimal value, and the cycle with expander is optimum cycle in the all cycles.
