Performance measurement of CO2 heat exchangers.
Author(s) : HWANG Y. H., JIN D. H., RADERMACHER R., et al.
Summary
In order to design components and systems for carbon dioxide, a performance database should be established. As part of the efforts for developing such a performance database, a set of tests were conducted for a fin-and-tube type heat exchanger serving as a gas cooler in the transcritical cycle by using a specially designed test facility. Furthermore, to provide a better understanding of the performance of a carbon dioxide gas cooler, a set of parametric measurements at various inlet air temperatures and velocities, refrigerant mass flow rates, and operating pressures were conducted. The test results of one CO2 gas cooler are reported in the current paper.
