In this paper, the gas cooler in trans-critical CO2 refrigeration cycle system is studied experimentally. Research shows that: the temperature different between the inlet CO2 and the cooling water changes in a wide range as the heat rejection pressure changes, but the outlet CO2 temperature of the gas cooler is almost unchanged; the relative pressure drop is only about 1% when the heat rejection pressure is 9MPa in the system; with the increase of gas cooler exit temperature, the refrigerating capacity decreases linearly first, and the latter becoming more and more stable, but the compression work is linearly increased; on the experimental conditions, the COP decreased about 25% when the outlet temperature of the gas cooler ranged from 30°C to 37°C.
