Abstract

The invention discloses a draught fan control method and device, and an air conditioner outdoor unit. The draught fan control method comprises the steps of acquiring the air conditioner system pressure and the external environmental temperature; enabling the air conditioner system pressure and the external environmental temperature to meet preset conditions by adjusting the operating frequency of a first draught fan; and enabling the outlet temperature of a first heat exchanger and the outlet temperature of a second heat exchanger to be equal by adjusting the operating frequency of a second draught fan. According to the method, the upper heat exchanger and the lower heat exchanger of the outdoor unit are made to have the same heat exchange effect, and the heat exchange effect of the heat exchangers of the outdoor unit is improved. By means of the method, the heat exchangers can be conduct heat exchange uniformly, ineffective power consumption of a motor is reduced, and the draught fans can save more energy.

Description

technical field [0001] The invention relates to the field of air conditioner control, in particular to a fan control method and device, and an air conditioner outdoor unit. Background technique [0002] The side-outlet dual-fan heat pump outdoor unit, the condenser corresponding to the upper fan is the upper condenser, and the lower fan is corresponding to the lower condenser. When the refrigerant dissipates heat in the condenser, due to the effect of gravity, the refrigerant flow ratio at the upper part of the condenser in cooling mode is The flow in the lower part is large, and the heating mode is the opposite. [0003] When the load of the unit is low, the flow difference between the upper and lower condensation becomes more obvious. The difference in flow rate greatly reduces the utilization rate of the heat exchanger. Contents of the invention [0004] In view of the above technical problems, the present invention provides a fan control method and device, and an out...
