The preset standard temperature value answered calculates all cabinets and corresponds to air-conditioning i in the ambient temperature deviation coefficient r at k+1 momenti(k+1)；
Step 3: according to air-conditioning i the k moment power coefficient ci(k) and the cabinet as its effective object is at the k+1 moment
Temperature deviation coefficient ri(k+1) air-conditioning i is calculated in the temperature controlling elements u at k+1 momenti(k+1)；
Step 4: according to the temperature controlling elements u of air-conditioning ii(k+1) realtime power of the feedback control air-conditioning i at the k+1 moment,
It repeats the above steps, so that the environment temperature of cabinet keeps dynamic equilibrium at preset standard temperature.
In the present embodiment, in the step 1, air-conditioning i is calculated in the formula of the power coefficient at k moment are as follows:

Step 21: the normalized temperature coefficient v in k+1 moment measurement point j is calculated according to the ambient temperature value of measurement point jj
(k+1), calculation formula is as follows:
