Problems solved by technology

[0005] The invention provides a method for starting a fan in an outdoor unit and an outdoor unit, which solves the problem that the outdoor unit misjudged that the built-in drive DC fan was faulty due to the reverse operation of the built-in drive DC fan when it was started, and the operating load of the outdoor unit was too high. Big problem, when it is judged that the built-in drive DC fan starts up against the wind, it can be quickly restored to normal operation

Abstract

The embodiment of the invention discloses a method for starting a fan in an outdoor unit and the outdoor unit, which relate to the technical field of air conditioning and solve the misjudgment failure of the outdoor unit caused by the reverse operation of the built-in drive DC fan affected by strong wind during startup. Determine the first speed of the built-in drive DC fan, receive the initial VSP voltage, and judge whether the first speed is greater than or equal to the safe speed. If the first speed is greater than or equal to the safe speed, run it for the first preset time under the initial VSP voltage, then confirm The second speed of the built-in drive DC fan, judge whether the second speed is greater than or equal to the first speed, if the second speed is greater than or equal to the first speed, drive the built-in drive DC fan to run with the first VSP voltage, if the second speed is less than the first speed First speed, drive the built-in drive DC fan with the second VSP voltage, the second VSP voltage is greater than the first VSP voltage, if the first speed is lower than the safe speed, drive the built-in drive DC fan with the first VSP voltage to run.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of air conditioning, and in particular to a method for starting a fan in an outdoor unit and the outdoor unit. Background technique [0002] Nowadays, air conditioners are installed in more and more places, and the installation occasions are various, such as the seashore and other places where there is strong wind. In this occasion, the outdoor unit is exposed to the outside, and the built-in drive DC fan contained in it may be blown by strong wind. . Since the built-in drive DC fan helps to improve the energy efficiency level of the air conditioner, it is required that the built-in drive DC fan can still operate normally and reliably under the influence of strong wind. [0003] Under normal circumstances, after the outdoor unit is started, the main control module of the outdoor unit can input the speed control voltage (VSP voltage) to the built-in drive DC fan, and the built-in driver...
