Study On Application Of Direct Evaporative Cooling System In Large Scale Building Of Steel Plant

With the rapid improvement of the economy and people's living standard, central air condition systems have been widely used in living and industrial building .As the result,Energy consumption of central air condition system is larger than before. So it is essential that appropriate and economical central air condition system is choosed and designed in project design and research.Direct evaporative system can decrease the temperature in doors by water evaporation. refrigeration is realized by water evaporation. In the direct evaporative cooling process, water evaporates and changes to vapour, and the process never circulates.It can be maintained by makeup water.In some special conditions , direct evaporative cooling system can be adapted to decrease the temperature in doors.The paper is concerned on direct evaporative cooling system by means of designing and research of a large scale building in steel plant .Direct evaporative cooling system can be adapted in hot and humid area such as Shanghai to decrease the temperature in doors.It has large economic and social value and can be extended to apply on such kind of projects in steel plants. In hot and humid climates of direct evaporative cooling system must be a prerequisite that there is no specific requirements of indoor air humidity, the volume of ventilation must meet certain air changes rate.
