When the running time is larger than or equal to the preset time length, the current environment temperature and the current exhaust temperature are detected, because the compensation values of the exhaust temperature sensing bulbs are different under different environment temperatures, the compensation value is obtained through experimental data, a high-temperature limit Tmax is carried out on the environment temperature at the moment, the operation of the air conditioning system is more reliable, when the outside working condition is higher, the evaporation pressure is high, the inside working condition is relatively higher, and at the moment, the condensation pressure is easily overhigh, so that the reliability of the air conditioning system is influenced.

And then compared with the target exhaust temperature Tmk based on the compensated exhaust bulb temperature Tki. The target exhaust temperature Tmk has a range, i.e., a target exhaust temperature range [ Tmk- δ t, Tmk + δ t ]. If the Tki belongs to [ Tmk-delta t, Tmk + delta t ], maintaining the current compressor frequency, the rotating speed of the inner fan, the rotating speed of the outer fan and the step number of the electronic expansion valve unchanged; if Tki is less than (Tmk-deltat), increasing the frequency of the compressor, reducing the rotating speed of the inner fan, increasing the rotating speed of the outer fan and increasing the opening of the electronic expansion valve; if Tki is greater than (Tmk + δ t), the compressor frequency is reduced, the inner fan speed is increased, the outer fan speed is reduced, and the opening of the electronic expansion valve is reduced. [ Tmk-deltat, Tmk + deltat ] is a sterilization effective temperature and sterilization reliability temperature interval.
