Embodiment Construction

[0064] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0065] This embodiment aims at the current air conditioner, the air outlet direction of the outdoor unit is fixed, but the wind direction of the outdoor environment is very random, which affects the heat exchange effect of the outdoor unit, and proposes a method that can be used according to the wind direction of the outdoor environment. Changing the technology of automatically adjusting the air outlet direction of the outdoor fan of the air conditioner, and then under the premise of ensuring sufficient heat exchange by the heat exchanger, significantly reduces the operating power consumption of the outdoor unit, and realizes the efficient operation of the air conditioner.

[0066] Such as Figure 4 As shown, in order to realize the intelligent adjustment of the direction of the outdoor fan, this embodiment first adds a measuring instrument 2 ...

Abstract

The invention discloses a method for controlling an outdoor fan of an air conditioner according to the environmental wind direction. The method includes detecting the environmental wind direction first; setting the rotation of the outdoor fan to be forward so that wind is discharged from an air outlet when the environmental wind blows from an air inlet to the air outlet of the outdoor fan; and setting the rotation of the outdoor fan to be reverse so that wind is discharged from the air inlet when the environmental wind blows from the air outlet to the air inlet of the outdoor fan. According to the method, the operation status of the outdoor fan is adjusted according to the environmental wind direction, and therefore a system can utilize natural resources fully to achieve efficient operation of the air conditioner. When the environmental wind direction is opposite to the air outlet direction of the existing air conditioner, the air volume can be prevented from reducing or even be improved and complete heat exchange of a heat exchanger can be guaranteed through shutdown or reverse rotation control of the outdoor fan; and when the environmental wind direction is the same with the air outlet direction of the existing air conditioner, the outdoor fan is controlled to be shut down or the rotation speed is reduced, therefore the overall operation power of the air conditioner is reduced and efficient and energy-saving functions are performed when the heat exchange is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of air conditioning and refrigeration engineering, and in particular relates to a method for controlling an outdoor fan of an air conditioner. Background technique [0002] Most of the current air conditioner products include indoor unit and outdoor unit. The outdoor unit is responsible for cooling or heating, and the indoor unit is responsible for transporting cold or hot air to the room to achieve the effect of cooling or heating. [0003] During the cooling or heating operation of the outdoor unit, the heat released by the heat exchanger needs to be quickly dissipated into the air by the outdoor fan. For traditional air conditioner outdoor fans, the direction of rotation is fixed, and the speed is only controlled by the operation of the air conditioner itself, and is not affected by the external wind direction and wind speed. The traditional control method of the outdoor fan of the air conditioner has ...
