Wherein, controller detects the state of high-pressure switch in real time at start run duration; high-pressure switch has and switches on and off two states; connect and represent that high-pressure does not reach that high-pressure switch is preset is pressed into protection value, disconnect and represent that high-pressure meets or exceeds that high-pressure switch is preset is pressed into protection value.
S3, air-conditioner maintain current operating conditions; That is, high-pressure switch is on-state, and continues the work of remaining stationary after continuing the second Preset Time, represents that current high-pressure does not exceed the high voltage protective value of default, is in normal operating conditions.
S4, controller control electric expansion valve and open with the first default aperture and run the first Preset Time;
Wherein, first presets aperture is preferably 100%, that is, electric expansion valve is all opened; Its objective is and carry out off-load rapidly after air-conditioning high-pressure reaches default protection value, to ensure the safe operation of air-conditioning system.
S5, controller detect the state of high-pressure switch in real time, if high-pressure switch is off state, and continue the second Preset Time, then perform step S6; If high-pressure switch is on-state, and continue the second Preset Time, then perform step S7;
Preferably, the second Preset Time is set as 10-20 second.
S6, air-conditioner are shut down and are reported pressure protect fault;
That is, after off-load electric expansion valve is opened completely, still there is action in air-conditioning high-pressure switch, then air conditioner quits work, and report and submit fault to keep in repair.
S7, controller control electric expansion valve and open with the second default aperture and run the first Preset Time, and second presets aperture is less than the first default aperture, to reduce refrigerant bypass amount, realizes air conditioner refrigerating amount and promotes gradually;
S8, controller detect the state of high-pressure switch in real time, if high-pressure switch is off state, and continue the second Preset Time, then return and perform step S4; If high-pressure switch is on-state, and continue the second Preset Time, then perform step S9;
And the second default aperture is 60%-80%, and certainly, default aperture can be arranged according to actual needs flexibly, be less than the first default aperture as long as meet.
S9, controller control electric expansion valve and maintain the second default aperture.
In addition; continue if want to reduce the refrigerant bypass amount that high-pressure side flows to low-pressure side; control electric expansion valve by controller open to be less than the described second aperture presetting aperture and to continue to run; thus make high-pressure under the prerequisite of high voltage protective value being no more than default, farthest ensure high-temperature refrigeration ability.
Wherein, electric expansion valve carries out stepless opening degree adjustment under the control of the controller or multistage aperture regulates, and such as: electric expansion valve is magnetic valve, magnetic valve can carry out aperture adjustment under the control of the controller.Certainly, the structure of electric expansion valve is not limited to, and can regulate aperture as long as meet.
Visible, the present embodiment one mainly adopts secondary to preset aperture (first presets aperture, second presets aperture) and controls; The aperture of electric expansion valve can be controlled in real time according to refrigeration system mesohigh pressure switch state; to make high-pressure under the prerequisite of high voltage protective value being no more than default; reduce the refrigerant bypass amount that high-pressure side flows to low-pressure side to greatest extent; can ensure that air-conditioner normally runs under high ambient conditions, ensure that high-temperature refrigeration ability to greatest extent again.
Embodiment two
The technology contents not repeated description that the present embodiment two is identical with embodiment one, disclosed in embodiment one, content also belongs to content disclosed in the present embodiment two, the present embodiment two and embodiment one are distinguished and are: the present embodiment two adopts three grades of default apertures to control, that is, the present embodiment two increases one-level and presets aperture (that is, comprise first and preset aperture, the second default aperture and the 3rd default aperture) on the basis of embodiment one.
Be specially: in step s 9, controller controls electric expansion valve and opens with the 3rd default aperture and run the first Preset Time, and the 3rd presets aperture is less than the second default aperture; Wherein, the 3rd default aperture is preferably 30%-50% in the present embodiment.
Afterwards, continue to perform step S10, controller detects the state of high-pressure switch in real time, if high-pressure switch is off state, and continue the second Preset Time, then return and perform step S7, what deserves to be explained is, when returning execution step S7, needing again to continue to perform; If high-pressure switch is on-state, and continue the second Preset Time, then perform step S11;
S11, controller control electric expansion valve and maintain the 3rd default aperture.Now, compare embodiment one under equal conditions, this enforcement two decreases refrigerant bypass amount more to greatest extent.
Certainly; under the prerequisite of high voltage protective value that high-pressure is no more than default; further reduce the refrigerant bypass amount that high-pressure side flows to low-pressure side if think, also control electric expansion valve by controller and open to be less than the described 3rd aperture presetting aperture and to continue to run.
Visible, the present embodiment two adopts three grades of default apertures (first presets aperture, second presets aperture, the 3rd default aperture) to control; After air-conditioning start runs and reaches the high voltage protective pressure of setting; first control electric expansion valve to open to reduce high-pressure rapidly with larger aperture; air-conditioning protection is avoided to shut down or overload of compressor protection; then; controller controls electric expansion valve and reduces aperture (two-stage) step by step to reduce refrigerant bypass amount, and air conditioner refrigerating amount is promoted gradually.
