The Research To Improve The Vacuum Of Direct Air Cooling Unit

This paper analyzes the problems of direct air cooling unit running,Five windshield wall structures were proposed to increase direct air cooling unit vacuum, namely the installation of a wind wall 、 under the wind wall 、 horizontal baffle 、 along the horizontal baffle installation.Application Fluent software for a 600 MW Direct Air Cooling Unit to simulate,analyzed the distribution of various wind wall air-cooled island around temperature and velocity field; calculated the amount of wind turbine and condenser heat transfer efficiency in different environments wind speed with various wind wall structure, analyzed and compared the influence of condenser vacuum on the lower edge of the baffle installation or without.
