The value range of the first rotating speed n1 can be 1000-1050 rpm, and the value range of the second rotating speed n can be 2700-3000 rpm.
In a preferred embodiment of the present invention, the first speed n1 may be 1020rpm and the second speed n may be 2800 rpm.
And S2, detecting the environmental temperature and the environmental humidity of the environment where the mobile air conditioner is located when the running time of the mobile air conditioner reaches a first preset time.

And S3, adjusting the rotation speed of the air exhaust motor and the atomization motor according to the environment temperature and the environment humidity.
Specifically, it can be determined whether the ambient temperature T is greater than or equal to a first preset temperature TSAnd whether the ambient humidity RH is greater than or equal to a first preset humidity RHS. If the ambient temperature T is greater than or equal to the first preset temperature TSAnd the environment humidity RH is more than or equal to a first preset humidity RHSThen, the exhaust motor is controlled to operate at the first speed n1, and the atomizing motor is controlled to operate at the second speed n, so as to rapidly reduce the ambient temperature and the ambient humidity of the environment where the mobile air conditioner is located, thereby providing a comfortable environment for the user. If the ambient temperature T is greater than or equal to the first preset temperature TSAnd the environment humidity RH is less than the first preset humidity RHSThen the exhaust motor is controlled to run at a first speed n1, and the atomization motor is controlled to stop running,so as to reduce the power consumption of the atomizing motor.

For example, if the ambient temperature T is greater than or equal to 26 ℃ and the ambient humidity RH is greater than or equal to 30%, the exhaust motor is controlled to operate at a rotation speed of 1020rpm, and the atomizing motor is controlled to operate at a rotation speed of 2800rpm, so as to rapidly reduce the ambient temperature and the ambient humidity of the environment where the mobile air conditioner is located, thereby providing a comfortable environment for the user. And if the ambient temperature T is more than or equal to the first preset temperature of 26 ℃ and the ambient humidity RH is less than 30%, controlling the exhaust motor to rotate at the rotating speed of 1020rpm, and controlling the atomizing motor to stop operating so as to reduce the power consumption of the atomizing motor. And if the ambient temperature T is less than 26 ℃ and the ambient humidity RH is more than or equal to 30%, controlling the exhaust motor to operate at 612rpm, and controlling the atomizing motor to operate at 2800rpm to reduce the power consumption of the exhaust motor.

It should be understood that the ambient temperature T and the ambient humidity RH detected within 3min may not accurately represent the current actual ambient temperature and ambient humidity, and therefore, in an embodiment of the present invention, the consistency between the ambient temperature T and the ambient humidity RH and the comparison result of 26 ℃ and 30% respectively must be continuously accumulated for 3min to be effective, otherwise, the comparison is performed again after the accumulated time is cleared. Specifically, when the environmental temperature T is more than or equal to 26 ℃ within 3min, judging that the environmental temperature T is more than or equal to 26 ℃; when the environmental temperature T is less than 26 ℃ within 3min, judging that the environmental temperature T is less than 26 ℃; when the environmental humidity RH is more than or equal to 30% within 3min, judging that the environmental humidity RH is more than or equal to 30%; and when the environmental humidity RH is less than 30% within 3min, judging that the environmental humidity RH is less than 30%. This makes it possible to determine the validity and reliability of the result.
In an embodiment of the present invention, after the rotation speeds of the air exhaust motor and the atomizing motor are adjusted and the air exhaust motor and the atomizing motor are controlled to operate for the second preset time t2 at the adjusted rotation speeds, the ambient temperature and the ambient humidity of the environment where the mobile air conditioner is located may be re-detected, and the rotation speeds of the air exhaust motor and the atomizing motor may be adjusted again according to the re-detected ambient temperature and ambient humidity, so that the rotation speeds of the air exhaust motor and the atomizing motor may change with the change of the ambient temperature and the ambient humidity of the environment where the mobile air conditioner is located.
