Step 401, it is judged that whether air quality value is more than air quality threshold.
Wherein, the equipment such as server in server room are had large effect by air quality.When air quality is severe, and time beyond predetermined threshold value, introduce outdoor natural wind, substantial amounts of graininess pollutant or pollution gas can be introduced in machine room.At this moment, should use refrigeration station cooling mode that machine room cooling is regulated, thus may determine that machine room cooling mode is refrigeration station cooling mode.
Step 402, it is judged that whether the temperature value outside machine room is more than temperature threshold.
When the temperature value outside machine room is too high, introduce outdoor natural wind, it is impossible to reduce indoor temperature, or temperature reduces inconspicuous, at this moment, should use refrigeration station cooling mode that machine room cooling is regulated, thus may determine that machine room cooling mode is refrigeration station cooling mode.
