In the embodiment of the present invention, the operation mode of the wind-side natural cooling device is switched and controlled according to the detected outdoor environment parameters, and the operation mode includes a direct cooling mode and an indirect cooling mode; thus, the wind-side natural cooling device is In the direct cooling mode, the imported outdoor air is sent into the data room to cool down the data cabinets in the data room; in the indirect cooling mode, the air side natural cooling device utilizes the introduced The outdoor air cools the air discharged from the data room, and sends the cooled air into the data room, so as to cool down the data cabinets in the data room.

In the technical solution provided by the embodiment of the present invention, by using the natural cooling device on the wind side, the outdoor air is used to cool the data room in the data center without using the refrigeration unit and water resources, thereby reducing the cost of the air conditioning system in the refrigeration unit. Energy consumption, therefore, can solve the problem of high energy and water consumption in the prior art when the cooling unit is used to cool the data cabinet, and save energy consumption and water resources.

In the direct wind side mode, the natural cooling device on the wind side introduces outdoor air, and uses the temperature difference between the outdoor air and the air in the data room to cool down the data cabinets in the data room. The energy saving effect in side mode is very significant. However, in the direct wind side mode, the wind side natural cooling device has higher requirements on the deployed outdoor environment. Otherwise, when the outdoor environment is poor, the direct contact of outdoor air to the data cabinets in the data center will cause permanent damage. Therefore, the applicable application scenarios of the wind-side natural cooling device in the direct wind-side mode are limited,

In the indirect wind side mode, the wind side natural cooling device uses the introduced outdoor air to exchange heat and cool down the indoor air, but the two are not in direct contact. Therefore, in the indirect wind side mode, the wind side natural cooling device has an The environmental requirements are not high, and it can be applied to a variety of application scenarios. However, compared with the direct wind side mode, the wind side natural cooling device needs to consume more energy in the indirect wind side mode.
