COOLING APPARATUS AND ITS METHOD OF INTERNET DATA CENTER

摘要

PURPOSE: A cooling apparatus of a data center and a method thereof are provided to sense temperature/humidity of internal/external air and circulate the internal/external air according to the temperature/humidity, thereby keeping temperature/humidity inside the data center by a set range value. CONSTITUTION: An inhalation/discharge duct(200) inhales internal air of a back side of server racks(100) and discharges it to the outside of a data center or circulates it inside the data center. A thermo-hygrostat(300) controls an inhalation/discharge damper according to temperature/humidity of external/internal air of the data center and discharges the internal air to the outside or discharges the external air to the inside of the data center. The thermo-hygrostat blocks inhalation of the external air and cools the internal air and keep the humidity of the external air constant to discharge the external air to the inside of the data center.
