Experimental study of supercritical CO2 gas cooling in a microchannel gas cooler.

Author(s) : ZHAO Y., OHADI M. M.

Summary

An experimental study was conducted to investigate the heat transfer characteristics of supercritical CO2 gas cooling down in a microchannel gas cooler over a range of operating conditions encountered in typical residential heat pumps. The microchannels used in the present study had a hydraulic diameter of approximately 1 mm. The experiments were conducted to evaluate the heat transfer performance of the microchannel gas cooler at different test conditions by varying airflow rates, air temperatures, refrigerant inlet temperatures, and mass flow rates. All experimental results are tabulated in the present paper.
