Individual precision air conditioner 7 is handled indoor return air, indoor return air is reached ventilation state point, is then sent into through multiple air outlets 6
It is that data center 1 provides cold in data center 1, to meet the refrigeration requirement of data center 1, makes the temperature in data center 1
Field reaches requirement.
(2) winter：
Winter, some areas dust storm was big, and the humidity and cleanliness factor being easily caused in data center 1 can not due to dry
Requirement is reached, data center 1 can now be cooled down using wet film cooling humidification system, while also air is humidified,
It is avoided that winter needs the energy consumption by the humidification of precision air conditioner 7, saves energy resource consumption, take full advantage of cooling server cabinet
The dry air energy that the heated dry air discharged after group 3 has；In addition, wet film cooling humidification system also can carry out wet type mistake to air
Filter, the requirement in data center 1 to cleanliness factor can be also met while meeting and humiture is required in data center 1；When wet
When the refrigeration that the cold that film cooling humidification system is provided can not meet data center 1 is required, multiple precision air conditioners 7 can be opened and combined
Cooling.
Data center of the present invention is applied to data center 1 with wet film cooling humidification and mechanical refrigeration associative form cold supply system
It is interior, the air current composition in data center 1 can be optimized, the closing passage of heat 4, cold passage 2 is formed respectively in data center 1, can have
Effect avoids the energy dissipation that hot and cold air blending is caused in data center 1, can realize to the green of data center 1, energy-conservation and environmental protection
Requirement.
