Overview

   The heat transfer characteristics of supercritical CO2 are studied from two aspects of experiment and numerical value by using natural refrigerant CO2 as the research object in high temperature and high pressure carbon dioxide experimental system.The critical temperature and pressure of CO2 are about 30 and 7.1Mpa,so the pipelines and containers of the whole experimental system need to withstand pressure more than 15Mpa and have good sealing performance.The instrument simulates the compression process of supercritical CO2 by means of electric heating to make CO2 reach supercritical state,and then the whole experimental system is cooled by the refrigeration system.
