Problems solved by technology

This design method often encounters problems in the actual air conditioner installation. The most common problem is that the actual installed model does not match the required air duct length. Although the air conditioner is barely installed, the air volume is either too large or too small. Uncomfortable and affects user experience
[0003] Therefore, how to avoid the mismatch between the indoor unit model and the length of the air duct, resulting in too large or too small air volume, and how to improve the comfort of users has become a technical problem to be solved urgently.

Embodiment 1

[0052] According to an embodiment of the present invention, the step of detecting the external static pressure of the indoor unit specifically includes: after controlling the indoor fan to work at a predetermined wind speed / predetermined speed for a predetermined time, by installing it on the indoor unit of the air conditioner, The wind pressure sensor detects the static pressure outside the machine.

[0053] In this embodiment, the wind pressure sensor can be directly used for detection.

Embodiment 2

[0055] According to an embodiment of the present invention, the step of detecting the external static pressure of the indoor unit specifically includes: after controlling the indoor fan to work at a predetermined wind speed / predetermined speed for a predetermined time, detecting the operating current of the indoor fan, according to The operating current determines the external static pressure.

[0056] In this embodiment, since there is a certain correlation between the running current of the indoor fan and the static pressure outside the machine, the static pressure outside the machine can be determined by detecting the running current of the indoor fan. Wherein, the correlation between the operating current of the indoor fan and the external static pressure may be stored in advance, so that when the operating current of the indoor fan is detected, the external static pressure can be directly determined.

Embodiment 3

[0058] According to an embodiment of the present invention, the step of detecting the external static pressure of the indoor unit specifically includes: after controlling the indoor fan to work at a predetermined wind speed / predetermined speed for a predetermined time, detecting the actual speed of the indoor fan, according to The actual rotational speed determines the external static pressure.

[0059] Similarly, since there is a certain correlation between the actual rotational speed of the indoor fan and the external static pressure, the external static pressure can be determined by detecting the actual rotational speed of the indoor fan. Wherein, the correlation between the actual rotational speed of the indoor fan and the external static pressure may be stored in advance, so as to directly determine the external static pressure when the actual rotational speed of the indoor fan is detected.

[0060] According to an embodiment of the present invention, before the step of s...

Abstract

The invention provides a control method and device for an indoor fan of an air conditioner. The control method for the indoor fan of the air conditioner comprises the steps of detecting exterior static pressure of the indoor unit of the air conditioner during operation of the air conditioner at the first time; setting the reference air damper / reference revolving speed of the indoor fan according to the exterior static pressure; controlling the air damper / revolving speed of the indoor fan based on the reference air damper / reference revolving speed. By adopting the technical scheme provided by the invention, the problem that the air volume is too large or too small due to a reason that the type of the indoor unit is not matched with the length of an air pipe can be avoided, and the comfort experience of the user is guaranteed to be better.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a method for controlling an indoor fan of an air conditioner and a control device for an indoor fan of an air conditioner. Background technique [0002] At present, in the existing air duct type air conditioners, different indoor unit models are designed according to different air duct lengths, or the power of the indoor fan is changed to cope with different air duct lengths. This design method often encounters problems in the actual air conditioner installation. The most common problem is that the actual installed model does not match the required air duct length. Although the air conditioner is barely installed, the air volume is either too large or too small. It feels uncomfortable and affects the user experience. [0003] Therefore, how to avoid the mismatch between the model of the indoor unit and the length of the air duct resulting in too large or too sma...
