| Abstract: | A tube-in-tube CO2 gas cooler whose nominal capacity is 4.5 kW is designed and developed. It is tested on performance test equipment of CO2 heat exchanger. The ex- perimental result indicates that the calculation results based on Petukhov-Popov-Kirilo heat transfer correlation and the experimental results are in good agreement, and the devia- tion between them is less than 10%. |

| Keywords: | CO2 gas cooler heat transfer correlation supercritical |
