Air conditioner using water vapor refrigerant for modular data center and data center comprising same

An air conditioner using a water vapor refrigerant for a modular data center, the air conditioner comprising:

• a box body, and
• an air conditioning system,
• wherein the air conditioning system comprises:
• a heat exchanger,
• a water atomization device,
• an air circulation side fan, and
• a vapor mist side fan,
• the heat exchanger has a plurality of columns of double-sided bidirectional micro-channels along an A-B direction and along a C-D direction, the vapor mist side fan is arranged outside the box body, the water atomization device is arranged on one side of the heat exchanger, the water atomization device comprises a pressure regulating device which cooperates with the water atomization device to form vapor mist, the vapor mist side fan is configured to form a negative pressure, so that the vapor mist evaporates under the negative pressure in the heat exchanger along the C-D direction to absorb heat and refrigerate;
• the air circulation side fan is configured to suck air in a space to be cooled into the micro-channels of the heat exchanger, and air is discharged into the space to be cooled after heat exchange is completed in the micro-channels.
