Fig. 1 is the flow chart of the control method of mobile air conditioner according to an embodiment of the present invention, as shown in Figure 1, the controlling party
Method includes:
S1 acquires the indoor working temperature under the current operating condition of mobile air conditioner.
For example, mobile air conditioner is run with dehumidification mode, pass through the current indoor working temperature of temperature sensor detection.
S2 obtains the ideal of the refrigerant for flowing through evaporator of corresponding current operating condition according to indoor working temperature and overheats
Degree.
Wherein, the ideal degree of superheat can be understood as the optimal degree of superheat range under current operating condition, the degree of superheat model
Enclose related with operating condition, the optimal degree of superheat range under the operating condition is mainly according to the degree of superheat range under the operating condition when refrigerating capacity maximum
It obtains, can be obtained by multiple groups experimental data.
The degree of superheat of evaporator is to embody the important parameter of refrigeration effect, and different operating conditions has corresponding degree of superheat range
So that refrigeration effect is best.In some embodiments of the invention, operating condition can be determined according to indoor working temperature, preceding
Phase can pass through experiment and obtain the corresponding relationship of operating condition and the ideal degree of superheat and be prestored using as historical data.

Refrigeration effect；If the current practical degree of superheat increases the revolving speed of upper fan still less than the lower limit value of the ideal degree of superheat, can
To increase the air capacity for carrying out heat exchange with evaporator, so as to take away more energy, so that the middle portion temperature of evaporator
Increase with the difference of outlet temperature, that is, increase the practical degree of superheat, so that the practical degree of superheat is moved closer in the ideal degree of superheat.
Alternatively, reducing the revolving speed of upper fan if the upper limit value of the ideal degree of superheat is still greater than in the current practical degree of superheat, that is, reducing
The positive energy exchange of evaporator so that the difference of the middle portion temperature of evaporator and outlet temperature is reduced, that is, reduces practical overheat
Degree, so that the practical degree of superheat is moved closer in the ideal degree of superheat, obtains optimal refrigeration effect.
Further, after mobile air conditioner runs the second preset time, according to the refrigerant for flowing through the evaporator
The current practical degree of superheat of temperature computation, and the ideal degree of superheat under the current practical degree of superheat and current operating condition is carried out
Compare, if the current practical degree of superheat increases the revolving speed for motor of fetching water still less than the lower limit value of the ideal degree of superheat, to increase
Cooling capacity is added, the practical degree of superheat of evaporator is increased, so that the practical degree of superheat is moved closer in the ideal degree of superheat, is obtained best
Effect；Alternatively, reducing turning for motor of fetching water if the upper limit value of the ideal degree of superheat is still greater than in the current practical degree of superheat
Speed reduces the practical degree of superheat of evaporator to reduce refrigerating capacity, so that the practical degree of superheat is moved closer in the ideal degree of superheat,
Obtain optimum efficiency.
In short, controlled as procedure described above according to the ideal degree of superheat and the practical degree of superheat switch of throttle part with
And the revolving speed of the revolving speed of upper fan and motor of fetching water, until the practical degree of superheat is in the ideal degree of superheat range under current working.
In practice, the revolving speed of upper fan is divided into two grades of height wind, and the revolving speed for motor of fetching water is divided into multi gear, can be according to upper
The revolving speed gear of blower adjusts the revolving speed of upper fan, for example, rotation speed of fan increases i.e. to be switched from low stepping to high wind file, equally
Ground can adjust the revolving speed of motor of fetching water according to the revolving speed gear for motor of fetching water, for example, can from high to low or from low to high
It is adjusted, until the practical degree of superheat that the refrigerant of evaporator is flowed through under current working is in the range of the ideal degree of superheat, with
Optimum efficiency is obtained, user experience is improved.
