[0067] When the outdoor ambient temperature is less than 30°C, the devices are not turned on.

[0068] When the outdoor ambient temperature is ≤38°C and ≥30°C, the centrifugal fan 3 draws cold air from the tobacco air conditioning room 5 and transports it into the cooling room 1, where it diffuses to the inside of the mechanical control equipment box 4 to achieve the effect of cooling it.
