For this reason, the present invention proposes a solution, can control effectively to air-conditioning condenser both sides laying dust, promotes the heat-exchange capacity of air-conditioner, extends air-conditioner service time.
The structure of the air-conditioner involved by the embodiment of the present invention can be as shown in Figure 1, this air-conditioner comprises housing 1, be arranged on the blower fan 2 in housing 1, control the controller etc. that blower fan 2 operates, the present embodiment controller can according to the switching of the operational mode of air-conditioner and applied load, control turning to of the blower fan 2 of air-conditioner to switch (wherein between forward and reverse, turning to of blower fan 2 can be as shown by the arrows in Figure 1, can set clockwise for rotating forward, be counterclockwise reversion), thus effectively can prevent air-conditioning condenser both sides laying dust, promote the heat-exchange capacity of air-conditioner, effective prolongation air-conditioner service time.
Particularly, as shown in Figure 2, present pre-ferred embodiments proposes a kind of air-conditioner control method, comprising:
Step S101, after air-conditioner start, obtains operational mode and the applied load of air-conditioner;
After air-conditioner start, it is refrigeration mode or heating mode that user can set air-conditioner as required, and sets the running temperature of air-conditioner.
Air-conditioner determines payload according to design temperature, outdoor environment temperature and other relevant parameters (such as indoor humidity, the quantity of the indoor set opened in multi-connected machine situation).
Under normal circumstances, the load of air-conditioner height and design temperature, environment temperature are relevant, when multi-connection operation, also relevant with the indoor set quantity of opening simultaneously.Generally, by judging whether indoor temperature reaches or close to design temperature, judge the load height of air-conditioner, indoor temperature and design temperature difference larger, then air-conditioner load is higher.
Step S102, according to operational mode and the applied load of described air-conditioner, the blower fan controlling described air-conditioner turns to rotation with first;
Step S103, in air-conditioner running, if the applied load monitoring air-conditioner changes and meets pre-conditioned, then switch the blower fan turning of air-conditioner, described blower fan is made to turn to rotation with second, with the heat exchanger surface dust of clean described air-conditioner, described second turn to turn to described first contrary.
After the operational mode determining air-conditioner and applied load, according to the operational mode of described air-conditioner and the change of applied load, control the blower fan forward or reverse of described air-conditioner.
Particularly, as a kind of application scenarios:
If the start operational mode of air-conditioner is refrigeration mode, then control blower fan turning in the following ways:
If air-conditioner applied load higher than load threshold value (this load threshold value can as required or experience setting, such as can value 20%-80%, the present embodiment does not do concrete restriction to this load threshold value, under normal circumstances, the indoor set load of this load threshold value and air-conditioner, the relating to parameters such as environment temperature and design temperature), the blower fan then controlling described air-conditioner adopts rotating forward mode to run, and ensures that heat exchange wind direction and refrigerant flow keep the mode of evaporation following current condensation adverse current to run.
In air-conditioner running, if monitor the applied load of air-conditioner lower than described load threshold value, higher than setting pressure threshold value, (this setting pressure threshold value can as required or experience setting then to judge system pressure, such as can value 1-5MPa, the present embodiment does not do concrete restriction to this setting pressure threshold value, under normal circumstances, this setting pressure threshold value is relevant with the operational reliability of air-conditioner); If system pressure is higher than setting pressure threshold value, then blower fan is kept to rotate forward, to ensure system pressure reliability.
If monitor system pressure lower than described setting pressure threshold value, then switch the blower fan turning of air-conditioner, described blower fan is reversed, and guarantee system is normally run, heat exchange can reach model machine and run instructions for use, and now the dust of air-condition heat exchanger outer surface can be effectively reduced and be attached on condenser.
Further, after making blower fan reversion, if monitor system pressure higher than described setting pressure threshold value, then switch the blower fan turning of air-conditioner, described blower fan is rotated forward, to ensure system pressure reliability.
In said process, if after air-conditioner start, the applied load monitoring air-conditioner lower than described load threshold value, then judges that whether system pressure is higher than setting pressure threshold value; If system pressure is higher than setting pressure threshold value, then controls blower fan and rotate forward, to ensure system pressure reliability; If system pressure is lower than described setting pressure threshold value, then control blower fan reversion, guarantee system is normally run.
It is above-mentioned when system pressure is higher than setting pressure threshold value, if system pressure is monitored lower than described setting pressure threshold value follow-up, then switch the blower fan turning of air-conditioner, described blower fan is reversed, guarantee system is normally run, heat exchange can reach model machine and run instructions for use, and now the dust of air-condition heat exchanger outer surface can be effectively reduced and be attached on condenser.In like manner, after making blower fan reversion, if monitor system pressure higher than described setting pressure threshold value, then switch the blower fan turning of air-conditioner, described blower fan is rotated forward, to ensure system pressure reliability.
As another kind of application scenarios:
If the operational mode of air-conditioner is heating mode, then control blower fan turning in the following ways:
If described air-conditioner applied load is higher than load threshold value, then the blower fan controlling described air-conditioner adopts rotating forward mode to run, to ensure that air-conditioning heat exchange wind direction and refrigerant flow keep the mode of evaporation following current condensation adverse current to run.
In air-conditioner running, if the applied load monitoring air-conditioner is lower than described load threshold value, then judge that whether system pressure is higher than setting pressure threshold value; If system pressure is higher than setting pressure threshold value, then switch the blower fan turning of air-conditioner, described blower fan is reversed, and guarantee system normally runs heat exchange can reach model machine operation instructions for use, and now the dust of air-condition heat exchanger outer surface can be effectively reduced and be attached on condenser; If system pressure is lower than setting pressure threshold value, then blower fan is kept to rotate forward.
Further, switching the blower fan turning of air-conditioner, after making the reversion of described blower fan, if monitor system pressure lower than described setting pressure threshold value, then switching the blower fan turning of air-conditioner, described blower fan is rotated forward, ensure system pressure reliability.
In said process, if after air-conditioner start, the applied load monitoring air-conditioner lower than described load threshold value, then judges that whether system pressure is higher than setting pressure threshold value; If system pressure is higher than setting pressure threshold value, then control the blower fan reversion of air-conditioner, guarantee system normally runs heat exchange can reach model machine operation instructions for use; If system pressure is lower than setting pressure threshold value, then the blower fan controlling air-conditioner rotates forward, and now the dust of air-condition heat exchanger outer surface can be effectively reduced and be attached on condenser.
Further, switching the blower fan turning of air-conditioner, after making the reversion of described blower fan, if monitor system pressure lower than described setting pressure threshold value, then switching the blower fan turning of air-conditioner, described blower fan is rotated forward, ensure system pressure reliability.
In above-described embodiment, the load threshold value under refrigeration mode and heating mode and setting pressure threshold value, can set as required, and the parameter under two kinds of patterns can be corresponding identical, also can be different.
Thus by the switching of air-conditioner pattern and applied load, air-conditioner switches blower fan turning, effectively can prevent air-conditioning condenser both sides laying dust, promotes the heat-exchange capacity of air-conditioner, effectively extends air-conditioner service time.

3, when system pressure reduces, during lower than b, blower fan antiport, guarantee system normally runs heat exchange can reach model machine operation instructions for use, and now the dust of air-condition heat exchanger outer surface can be effectively reduced and be attached on condenser.
If not refrigeration mode, enter heating mode and judge, when being heating mode, control air-conditioner in the following way:
1, air-conditioner is when needs heavy-duty service, and blower fan adopts rotating forward mode to run, and ensures that heat exchange wind direction and refrigerant flow keep the mode of evaporation following current condensation adverse current to run;
2, when air-conditioner demand load is lower than c%, system pressure is judged.If system pressure is higher than blower fan antiport during d, guarantee system normally runs heat exchange can reach model machine operation instructions for use, and now the dust of air-condition heat exchanger outer surface can be effectively reduced and be attached on condenser;
3, when system pressure reduces, during lower than d, blower fan forward operates, and ensures system pressure reliability.
