The actual degree of superheat, and by the current actual degree of superheat compared with the preferable degree of superheat under current working, it is current to judge
Refrigeration；If for the current actual degree of superheat still less than the lower limit of the preferable degree of superheat, the rotating speed of increase fan can
To increase the air capacity that heat exchange is carried out 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 actual degree of superheat, to cause the actual degree of superheat to move closer in the preferable degree of superheat.
Or if the current actual degree of superheat reduces the rotating speed of fan, that is, reduced still above the higher limit of the preferable degree of superheat
The positive energy exchange of evaporator so that the middle portion temperature of evaporator and the difference of outlet temperature are reduced, that is, reduce actual overheat
Degree, to cause the actual degree of superheat moves closer in the preferable degree of superheat, to obtain optimal refrigeration.
Further, after mobile air conditioner runs the second preset time, according to the refrigerant for flowing through the evaporator
The current actual degree of superheat of temperature computation, and the preferable degree of superheat under the current actual degree of superheat and current operating condition is carried out
Compare, if the current actual degree of superheat, still less than the lower limit of the preferable degree of superheat, increase is fetched water the rotating speed of motor, to increase
Cold is added, increases the actual degree of superheat of evaporator, to cause the actual degree of superheat to move closer in the preferable degree of superheat, is obtained optimal
Effect；Or if the current actual degree of superheat reduces turning for motor of fetching water still above the higher limit of the preferable degree of superheat
Speed, to reduce refrigerating capacity, reduce the actual degree of superheat of evaporator, to cause the actual degree of superheat to move closer in the preferable degree of superheat,
Obtain optimum efficiency.
In short, as procedure described above according to the preferable degree of superheat and the actual degree of superheat come control the switch of throttle part with
And the rotating speed of the rotating speed of fan and motor of fetching water, until the preferable degree of superheat scope that the actual degree of superheat is under current working.
