Abstract

In this paper, the transcritical CO2 system is experimental studied, influence of heat source on system performance is analyzed. The experimental results show that the cooling water flow has no obvious effect on the system performance and it may be owed to the limitations of this experimental device. The cooling water temperature has a great impact on the system performance, COPh decreases about 21.7%, COPc decreases about 26.6% from the maximum value when the cooling water temperature range from 25 to 35 . The chilled water flow and temperature has a little impact on heating coefficient of performance, while it has a great impact on the cooling coefficient of performance. When COPh and COPc get the extreme value with the increase of chilled water flow, COPh decreases about 2.61%, COPc increases about 29%. COPh increases about 7.5%, COPc increases about 55.1% when the chilled water temperature ranges from 7 to 17 .
