Ducted air conditioner air guide device and control method thereof

Abstract

The invention relates to a ducted air conditioner air guide device and a control method thereof. The control method of the ducted air conditioner air guide device comprises the following steps that S1, a ducted air conditioner is started, and an air guide strip at an air outlet of the ducted air conditioner is controlled to be rotationally opened according to a preset air guide angle; S2, the running current of a motor and the actual static pressure are detected through a current detection unit and a wind pressure detection unit respectively, and the detected values are transmitted to a controller; S3, the controller compares the motor running current and the actual static pressure obtained through detection with the rated current and the rated static pressure respectively; and S4, the controller correspondingly adjusts the air guide angle of the air guide strip by controlling the swing motor according to the comparison result in the step S3.

Description

technical field [0001] The invention relates to the technical field of air conditioning, and more specifically, to an air guide device for an air duct machine and a control method thereof. Background technique [0002] Most of the existing ducted indoor units are not equipped with an air outlet panel (air guide device), and an air outlet frame with louvers that can be manually adjusted is generally installed during engineering installation. Because the louvers of the air outlet frame are adjusted manually, there will be uncomfortable air supply; for example, if the louvers are inclined downward too much, it may cause people under the air conditioner to feel "too cold"; If the downward inclination angle is too small, the hot air from the air conditioner may not blow down, making people feel that the heating effect of the air conditioner is not good. [0003] Of course, there are also a small number of ducted indoor units on the market, which are equipped with air outlet pane...

AI Technical Summary

Problems solved by technology

Because the louvers of the air outlet frame are adjusted manually, there will be uncomfortable air supply; for example, if the louvers are inclined downward too much, it may cause people under the air conditioner to feel "too cold"; If the downward inclination angle is too small, the hot air from the air conditioner may not blow down, making people feel that the heating effect of the air conditioner is not good

[0003] Of course, there are also a small number of ducted indoor units on the market, which are equipped with air outlet panels (air guide devices) as standard, but the cooling and heating air supply angles of this air outlet panel are pre-set and cannot be adjusted intelligently.

Therefore, even with this kind of air outlet panel, there will also be uncomfortable air supply

For example: when the length of the external air duct is too long and exceeds the rated static pressure of the system, the air volume at this time will decrease. The heating effect is not good; when the length of the external air duct is too short and far below the rated static pressure of the system, the air volume at this time will increase. People feel "too cold" or "too hot", which affects the comfort during use
