During the real-time aperture of real-time aperture control formula control choke valve, pass through the real-time pressure according to the on high-tension side pressure switch of air conditioner
Power adjusts the real-time aperture of choke valve in real time, can prevent the real-time pressure of pressure switch from exceeding the maximum pressure of pressure switch
Power is (such as：4.2MPa), and then ensure that air conditioner can give play to more preferable ability efficiency under identical working condition.
According to one embodiment of present invention, the adjustment unit 206 is specifically used for：When the real-time pressure of the pressure switch
When power is more than preset pressure, increase the real-time aperture of the regulating valve, to reduce the real-time pressure of the pressure switch, make described
Real-time pressure is less than or equal to the preset pressure, and when the real-time aperture of the regulating valve increases to the maximum of the regulating valve
During aperture, the real-time aperture of the choke valve is controlled to be equal to the maximum opening.
The control device 200 of throttle valve opening according to an embodiment of the invention, when the real-time pressure of pressure switch is more than
Preset pressure is (such as：When 3.8MPa), by increasing the real-time aperture of regulating valve, the real-time of pressure switch can be reduced in time
Pressure, real-time pressure is set to be less than or equal to the preset pressure, certainly, when the aperture of regulating valve gradually increases to maximum opening,
If the real-time pressure of pressure switch, still above preset pressure, the aperture that can control to adjust valve is equal to its maximum opening,
So that it is guaranteed that air conditioner can give play to more preferable ability efficiency under identical working condition, and can under more high environment temperature
By stable operation.
