1. An air conditioning system of data center using heat pipe comprising:
a cooling room that allows air within the data center to be drawn in by a first fan and circulated and fed back to the data center; a heat radiation room located separately from the cooling room, which room allows outside air to be drawn into the inside through a second fan and then discharged to the outside; a heat pipe installed such that evaporator and condenser are located in the cooling room and heat radiation room, respectively, wherein working fluid repeats phase changes of evaporation and condensation each in the evaporator and condenser, hence, the air passing through the cooling room is cooled by means of heat exchange with the evaporator and the air passing through the heat radiation room has heat exchange with the condenser; a sprayer installed in the heat radiation room and provided with a plurality of spray nozzles for spraying cooling fluid to the condenser; a cooling unit installed in the cooling room and cooling the air that passed the evaporator through heat exchange; dry bulb temperature measurement unit and wet bulb temperature measurement unit that each measures dry and wet bulb temperatures of outside air and output the temperatures as detection signal; and a control unit that receives the detection signal from the dry bulb temperature measurement unit and the wet bulb temperature measurement unit and control the sprayer and the cooling unit, wherein the control unit controls blowing power of the first and second fans depending on wet bulb temperature and dry bulb temperature that had been each measured by the wet bulb temperature measurement unit and dry bulb temperature measurement unit and controls the sprayer to spray the condenser with the cooling fluid in order to cool the condenser when the dry bulb temperature measured by the dry bulb temperature measurement unit exceeds a first set temperature and the wet bulb temperature measured by the wet bulb temperature measurement unit is less than a second set temperature, and controls the cooling unit to cool, together with the evaporator, air passing through the cooling room when the wet bulb temperature measured by the wet bulb temperature measurement unit exceeds the second set temperature. |
