When the mobile air conditioner operates in a refrigerating mode, the exhaust fan can timely exhaust hot air generated by heat exchange of the mobile air conditioner, meanwhile, cold air required in a room and generated by the mobile air conditioner cannot be exhausted, and refrigerating efficiency of the mobile air conditioner is guaranteed. When the mobile air conditioner is in heating operation, the exhaust fan can timely discharge cold air generated by heat exchange of the mobile air conditioner, meanwhile, hot air required by a room generated by the mobile air conditioner cannot be discharged, and the heating efficiency of the mobile air conditioner is ensured.
Further, the temperature difference is a heating temperature difference or a cooling temperature difference; wherein the refrigeration temperature difference is the temperature difference obtained by subtracting the set temperature from the exhaust temperature; the heating temperature difference is the temperature difference obtained by subtracting the exhaust air temperature from the set temperature.
In a specific embodiment, when the mobile air conditioner is in refrigerating operation, the temperature difference is the temperature difference obtained by subtracting the set temperature from the exhaust air temperature; when the mobile air conditioner is in heating operation, the temperature difference is the temperature difference obtained by subtracting the exhaust air temperature from the set temperature.

Further, according to the relationship between the temperature difference value and the temperature difference threshold value, controlling the rotation speed of the exhaust fan comprises: and if the temperature difference value is larger than a second temperature difference threshold value and smaller than a first temperature difference threshold value, controlling the rotating speed of the exhaust fan according to the ratio of the temperature difference value to the first temperature difference threshold value.
In one embodiment, if the temperature difference is greater than the second temperature difference threshold and less than the first temperature difference threshold, it indicates that the current temperature difference is between the temperature difference condition that the exhaust fan operates at the maximum speed and the temperature difference condition that the exhaust fan stops rotating, so the rotation speed of the exhaust fan is controlled according to the ratio of the temperature difference to the first temperature difference threshold, so as to realize intelligent control of the rotation speed of the exhaust fan and improve the heat exchange efficiency of the mobile air conditioner.
Further, said temperature is dependent onThe differential value control of the rotation speed of the exhaust fan comprises the following steps: r ═ r (r)max-rmin)*{1-cos[(ΔT/Ta)*(π/2)]}+rmin(ii) a Wherein r is the rotating speed of the exhaust fan; r ismaxThe maximum rotation speed of the exhaust fan; r isminThe minimum rotation speed of the exhaust fan; t isaIs a first temperature difference threshold; Δ T is the temperature difference.
In a specific embodiment, the larger the temperature difference value is, the more the difference between the exhaust temperature and the set temperature is, that is, the worse the exhaust fan is capable of timely exhausting the hot air generated during the cooling operation and the cold air generated during the heating operation of the mobile air conditioner, so that the rotation speed of the exhaust fan needs to be properly increased; on the contrary, the smaller the temperature difference is, the closer the exhaust temperature is to the set temperature, the smaller the rotation speed of the exhaust fan required by the mobile air conditioner is, and therefore the rotation speed of the exhaust fan needs to be properly adjusted.
For example, when the mobile air conditioner is in heating operation, if the temperature difference value obtained by subtracting the exhaust air temperature from the set temperature is between the first temperature difference threshold value and the second temperature difference threshold value, the rotation speed of the exhaust fan is controlled to increase along with the increase of the temperature difference value, so as to improve the heating efficiency; when the mobile air conditioner operates in a refrigerating mode, if the temperature difference value obtained by subtracting the set temperature from the exhaust temperature is between the first temperature difference threshold value and the second temperature difference threshold value, the rotating speed of the exhaust fan is controlled to be increased along with the increase of the temperature difference value, and therefore refrigerating efficiency is improved.
