Wherein, in predetermined power table, environment temperature climbing speed is in one-to-one relationship with electric heater operation power.
In an embodiment of the present invention, environment temperature climbing speed is calculated according to below equation (1) and obtained：
Ka=(Ts-T0)/t (1)
Wherein, Ka is environment temperature climbing speed, and t is the very first time, and T0 is the initial temperature of environment in very first time t,
Environment temperature when i.e. electric heater brings into operation, Ts is the end temp of environment in very first time t, i.e. the first preset temperature.
In one particular embodiment of the present invention, predetermined power table is as shown in table 1 below：

The power back-off factor corresponding to operation power after level 2, and downward is the second predesigned compensation value 0.1, that is, the operation after adjusting
Power is 0.2*0.1*Pm.
Further, after electric heater is with power 0.2*0.1*Pm operations 6s, if the environment temperature drop-out value value in 6s is
0.3 DEG C is less than 0.5 DEG C, then the operation power of electric heater is raised into a grade for power grade 3, and the operation power after downward
The corresponding power back-off factor is the first predesigned compensation value 1, that is, the operation power after adjusting is 0.3*1*Pm.
