It can be understood that the standard power of the external fan is the power value detected when the external fan normally operates according to the conventional control mode, and the upper limit power of the external fan is the power value detected when the air conditioner controls the rotation speed of the external fan to increase to the highest rotation speed according to the conventional control mode. In the conventional control mode, when the frosting of the condenser is serious, the external fan needs to increase the workload of the external fan to more rapidly discharge the surface cold energy of the condenser so as to ensure the heat exchange effect of the condenser, the workload of the external fan is the load of the external fan, the manner of increasing the workload of the external fan is to increase the rotating speed of the external fan, and the manner of increasing the rotating speed of the external fan is to increase the power of the external fan, so that when the power of the external fan reaches the upper limit power of the external fan, the situation that the condenser is severely frosted at the moment can be determined.
In the embodiment of the application, the frosting power threshold value can be set as an average value of the standard power of the external fan and the upper limit power of the external fan, and in fact, when the real-time power of the external fan exceeds the standard power of the external fan, the surface of the condenser can start frosting, but the frosting condition of the condenser is not serious at this time, the heat exchange effect of the condenser is not influenced, and when the average value is reached, the frosting condition of the condenser is serious to start influencing the heat exchange effect, so the average value is set as the frosting power threshold value.
104. Determining whether defrosting is performed according to the outdoor environment temperature, the real-time power of the external fan and the frosting power threshold value;
when the outdoor environment temperature is too low and the real-time power of the external fan exceeds the frosting power threshold, the frosting condition of the surface of the condenser can be predicted to be serious at the moment, the heat exchange effect is influenced, and the defrosting needs to be carried out in time.
105. If it is determined to defrost, the heater is activated.
In the embodiment of the application, the heater is a heating element arranged between the external fan and the condenser, so that after the heater is started, heat generated by the heater can be directly radiated to the surface of the condenser to timely remove frost on the surface of the condenser.
From the first embodiment, the following advantages can be seen:
the real-time operation power of the air conditioner external unit is obtained, whether defrosting parameter detection is carried out or not is determined according to the real-time operation power, the real-time operation power of the air conditioner external unit reflects the frequency of a compressor, the larger the frequency of the compressor is, the larger the quantity of refrigerant flowing in an air conditioner pipeline is, the more refrigerant enters a condenser to carry out heat exchange, and the more frosting condition of the condenser is easy to occur, so that whether the defrosting parameter detection is carried out or not can be determined by monitoring the real-time operation power of the air conditioner external unit, and the influence on the normal operation of the air conditioner is avoided; if the defrosting parameter detection is determined, acquiring outdoor environment temperature and real-time power of an external fan, determining a frosting power threshold according to the standard power of the external fan and the upper limit power of the external fan, and determining whether to defrost according to the outdoor environment temperature, the real-time power of the external fan and the frosting power threshold; if it is determined to defrost, then the heater is started, the heater is arranged on a heating element between the outer fan and the condenser, frosting on the surface of the condenser is timely removed through heat generated by the heater, defrosting efficiency is improved, heat exchange effect of the condenser is improved, heating effect of an air conditioner is guaranteed, the problem that user experience sense is reduced due to the fact that heating is needed to be stopped during defrosting is avoided, and comfort level of a user is improved.
