         2 . The air-conditioning system for the data computer room according to  claim 1 , wherein the humidifying apparatus ( 3 ) employs an atomization humidifier comprising a water tank, a booster water pump, and an atomization nozzle; and
 wherein the booster water pump is arranged inside the water tank, and a suction end and a discharge end of the booster water pump are respectively connected to the water tank and the atomization nozzle, such that water is pressurized and then discharged through the atomization nozzle.   
     
     
         3 . The air-conditioning system for the data computer room according to  claim 2 , wherein the water tank is connected to an external water supply pipeline. 
     
     
         4 . The air-conditioning system for the data computer room according to  claim 1 , wherein the humidifying apparatus ( 3 ) employs a wet-film humidifier comprising a wet film, a humidifying fan, and a sprinkler apparatus; and
 the wet film is supplied with water through the sprinkler apparatus, and the humidifying fan is arranged on a side of the wet film to evaporate water on the wet film.   
     
     
         5 . The air-conditioning system for the data computer room according to  claim 1 , wherein an electronic expansion valve is provided on a pipeline connecting the condenser ( 201 ) to the evaporator ( 101 ) to regulate a flow rate of a liquid flowing into the evaporator ( 101 ). 
     
     
         6 . The air-conditioning system for the data computer room according to  claim 1 , wherein the gas mixer ( 103 ) comprises a shell and a gas inlet and a gas outlet arranged at two ends of the shell, the shell having a cavity interconnected to both the gas inlet and the gas outlet;
 the gas inlet comprises an air inlet pipe and a cold gas inlet pipe, the cold gas inlet pipe being interconnected to one of outlets of the evaporator ( 101 ); and   an outlet end of the air inlet pipe is provided with a nozzle configured to concentrate air and spray the air into the cavity.   
     
     
         7 . The air-conditioning system for the data computer room according to  claim 5 , wherein the gas mixer ( 103 ) further comprises a valve body connected to the air inlet pipe. 
     
     
         8 . The air-conditioning system for the data computer room according to  claim 1 , wherein the control apparatus at least comprises a humidity sensor ( 4 ) and a controller ( 5 ), the humidity sensor ( 4 ) being electrically connected to the controller ( 5 ); and
 number of the humidity sensors ( 4 ) is at least two, and the at least two humidity sensors ( 4 ) are arranged inside and outside the computer room, respectively.   
     
     
         9 . A method for controlling operation of a humidifying apparatus of an air-conditioning system for a data computer room, comprising:
 S1: obtaining real-time indoor and outdoor humidity of the computer room by means of a humidity sensor;   S2: setting a humidity threshold H for the indoor humidity;   S3: calculating a differential D 1  between the outdoor humidity and the indoor humidity, and a differential D 2  between the indoor humidity and the humidity threshold H, and performing interval partition on the differential D 1  and the differential D 2  to form a plurality of differential intervals;   S4: selecting to switch on or off the humidifying apparatus according to the differential D 2 ; and   S5: separately recording humidification duration required for the indoor humidity to reach the humidity threshold H in different differential intervals.   umidifying apparatus ( 3 ) are stored and reported to the controller ( 5 ).
