6. The method of claim 5, wherein the step of processing the data center air according to the comparison result in the corresponding cooling mode comprises:
judging whether the outdoor air quality meets a preset condition or not;
if the outdoor air quality meets a preset condition, judging whether the outdoor air cleanliness meets the preset condition;
and if the cleanliness of the outdoor air meets the preset conditions, processing the air of the data center by adopting a mechanical refrigeration mode.
7. The method of claim 6, wherein the determining whether the outdoor air quality satisfies a predetermined condition further comprises:
if the outdoor air quality does not meet the preset condition, judging whether the outdoor air temperature detected by the first sensor is greater than a first preset value;
and if so, processing the air of the data center by adopting a mechanical refrigeration mode.
8. The method of claim 7, wherein the step of determining whether the outdoor air temperature detected by the first sensor is greater than a first predetermined value if the outdoor air quality does not satisfy a predetermined condition comprises:
if not, judging whether the outdoor air temperature detected by the first sensor is greater than a second preset value, wherein the second preset value is smaller than the first preset value;
if so, judging whether the air temperature detected by the third sensor is greater than a fourth preset value;
and if so, processing the air of the data center by combining a full fresh air mode and a mechanical refrigeration mode.
9. The method of claim 8, wherein the step of determining whether the outdoor air temperature detected by the first sensor is greater than a second predetermined value is further followed by:
if not, and the air temperature detected by the third sensor is less than or equal to the fourth preset value, judging whether the outdoor air temperature detected by the first sensor is greater than a third preset value;
if so, processing the air of the data center by adopting a full fresh air mode;
and if not, processing the air of the data center by adopting an indirect heat exchange mode.
10. The method according to any one of claims 5 to 9,
in the indirect heat exchange mode, the first air inlet is opened, outdoor air enters the upper part of the heat exchanger from the first air inlet through the first filter, the air subjected to heat exchange is discharged from the first air outlet under the action of the first fan matrix, meanwhile, indoor air passes through the second filter screen from the second air inlet, is subjected to heat exchange with the outdoor air through the lower part of the heat exchanger, and is discharged from the second air outlet under the action of the second fan matrix through the surface air cooler;
in a full-fresh air mode, the first air inlet, the first air port and the second air port are opened, outdoor air passes through the second filter from the first air inlet, passes through the second air port from the first air port, passes through the third air port, and is exhausted from the second air port under the action of the first fan matrix;
and when in the mechanical refrigeration mode, indoor air enters through the second air inlet, passes through the second filter, the second air port and the surface air cooler, and is discharged through the second air outlet under the action of the second fan matrix.
