Problems solved by technology

[0003] Usually in summer, when the outdoor temperature is high or the outdoor unit of the air conditioner is operating in a small space, the outdoor unit of the air conditioner is operating in a high temperature environment, and the fresh air with a high external temperature will enter the outdoor unit, and the condenser and the electronic control fins will be successively Convective heat exchange is carried out, and the temperature of the high-temperature fresh air continues to rise after exchanging heat with the condenser. At this time, the ability of convective heat exchange with the electronic control fins will be greatly reduced, resulting in the temperature of the electric control box being too high, and the electronic control components. Less than cooling, easy to burn out

Abstract

The invention discloses a method for controlling an outdoor fan of an air conditioner. The method comprises the following steps: during refrigeration running of the air conditioner, acquiring an electronic control preset position temperature of the outdoor fan of the air conditioner; judging whether the preset position temperature is greater than a first preset value or not; and if so, controlling the rotational direction of the outdoor fan of the air conditioner to be changed to a second direction from a first direction. The invention further discloses a device for controlling an outdoor fan of an air conditioner. According to the invention, the purposes of lowering the temperature of an electronic control box of the outdoor fan of the air conditioner, and cooling an electronic control component are realized, and the problems of liability to burn out and shortened service life of the electronic control component of the outdoor fan due to high-temperature running are solved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a method and device for controlling an outdoor fan of an air conditioner. Background technique [0002] At present, the application of air conditioners is very extensive, and it has gradually become an indispensable electrical appliance for people in summer. When the air conditioner is in the cooling mode, based on the conventional outdoor unit air duct structure, the centrifugal fan will draw fresh air from the outside environment from the rear and left side of the outdoor unit of the air conditioner. The fresh air first flows through the condenser for heat exchange. The refrigerant releases heat, so the temperature of the fresh air after heat exchange increases, and then the fresh air with increased temperature passes through the outdoor electronically controlled fins located at the rear of the condenser for convective heat exchange. [0003] Usually in summer, when t...
