Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that the embodiments described below are only for explaining the technical principle of the present invention and are not intended to limit the scope of the present invention.
Based on the problems that when the air conditioner is installed, the operation is complicated, the time and the labor are wasted and the precision is low in a mode of manually detecting the static pressure of the air duct. The invention provides a debugging method for an air conditioner, and aims to automatically detect the static pressure value of a current air duct by the air conditioner after the air conditioner is installed, so that the debugging method is simple and convenient to operate and high in precision.
Specifically, the air conditioner of the present invention includes an indoor fan and a controller, and as shown in fig. 1, the debugging method of the present invention includes: after the air conditioner is installed, the indoor fan is enabled to run at a preset rotating speed, and the duty ratio of the indoor fan is obtained; and obtaining the static pressure value of the current air duct according to the duty ratio of the indoor fan. Known from the background art, in the prior art, after the air conditioner is installed, an installer needs to detect the static pressure value of the air duct through a pressure gauge, the operation is complex, time and labor are wasted, and the precision is low. Therefore, the invention provides a debugging method for an air conditioner, and the air conditioner can automatically determine the static pressure value of the current air duct by adopting the debugging method. Specifically, after the air conditioner is installed, the controller controls the indoor fan to operate according to a preset rotating speed, obtains the duty ratio of the indoor fan, and then obtains the current air duct static pressure value according to the obtained duty ratio of the indoor fan.
It should be noted that, under the condition that the indoor fan rotation speed is constant, the duty ratio of the indoor fan corresponds to the duct static pressure value one to one. Before the air conditioner leaves a factory, the indoor fan can be operated at a preset rotating speed, duty ratios of the indoor fan under different air duct static pressure values are obtained in the operation process of the indoor fan, a duty ratio-static pressure value mapping table is obtained, and the duty ratio-static pressure value mapping table is stored in the controller. After the air conditioner is installed, the indoor fan runs at a preset rotating speed, the duty ratio of the indoor fan is obtained, then the corresponding air duct static pressure value can be inquired according to a duty ratio-static pressure value mapping table, and the air duct static pressure value is the current air duct static pressure value. Of course, the duty ratio and the static pressure value may be mapped in a formula or a mapping curve, and such flexible adjustment and change are not departing from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.
The technical solution of the present invention is described in detail below with reference to specific examples.
As shown in fig. 2, after the air conditioner is installed, the indoor fan is operated at a first preset rotation speed to obtain a first duty ratio of the indoor fan; enabling the indoor fan to operate at a second preset rotating speed, and obtaining a second duty ratio of the indoor fan; acquiring a first air duct static pressure value according to a first duty ratio of an indoor fan; acquiring a second air duct static pressure value according to a second duty ratio of the indoor fan; and determining the current air duct static pressure value according to the first air duct static pressure value and the second air duct static pressure value, wherein the first preset rotating speed is less than the second preset rotating speed.
Before the air conditioner leaves a factory, an indoor fan is enabled to operate at a first preset rotating speed, duty ratios of the indoor fan under different air channel static pressure values are obtained in the operation process of the indoor fan, a duty ratio-static pressure value mapping table I is obtained, the indoor fan is enabled to operate at a second preset rotating speed, the duty ratios of the indoor fan under the different air channel static pressure values are obtained in the operation process of the indoor fan, a duty ratio-static pressure value mapping table II is obtained, and the duty ratio-static pressure value mapping table I and the duty ratio-static pressure value mapping table II are stored in a controller of the air conditioner. In specific application, when the indoor fan operates at a first preset rotating speed, after a first duty ratio of the indoor fan is obtained, a first air channel static pressure value can be determined through a duty ratio-static pressure value mapping table I, and when the indoor fan operates at a second preset rotating speed, a second air channel static pressure value can be determined through a duty ratio-static pressure value mapping table II after a second duty ratio of the indoor fan is obtained.
Under the ideal condition, the first air duct static pressure value and the second air duct static pressure value are equal, but in the actual detection process, due to the interference of various factors, errors exist, and the errors can be reduced and the accuracy can be improved by obtaining the two air duct static pressure values. Specifically, in one possible scenario, after the first duct static pressure value and the second duct static pressure value are obtained, an average value of the first duct static pressure value and the second duct static pressure value may be directly calculated as the current duct static pressure value. In a preferred case, as shown in fig. 2, a variation value of the first air duct static pressure value relative to the second air duct static pressure value is compared with a preset value, and if the variation value of the first air duct static pressure value relative to the second air duct static pressure value is not greater than the preset value, an average value of the first air duct static pressure value and the second air duct static pressure value is taken as a current air duct static pressure value; and if the variation value of the first air duct static pressure value relative to the second air duct static pressure value is larger than the preset value, not taking the average value of the first air duct static pressure value and the second air duct static pressure value as the current air duct static pressure value. When the variation value of the first air duct static pressure value relative to the second air duct static pressure value is not more than the preset value, the first air duct static pressure value and the second air duct static pressure value are relatively close, in this case, it is most likely that the error between the first duct static pressure value and the second duct static pressure value is small, and at this time, the average value of the first duct static pressure value and the second duct static pressure value can be directly used as the current duct static pressure value, when the variation value of the static pressure value of the first air duct relative to the static pressure value of the second air duct is larger than the preset value, however, the difference between the static pressure value of the first air duct and the static pressure value of the second air duct is larger, in this case, it is most likely that the error in the first duct static pressure value and/or the second duct static pressure value is large, and at this time, the average value of the first air duct static pressure value and the second air duct static pressure value cannot be directly used as the current air duct static pressure value. And the change value of the first air duct static pressure value relative to the second air duct static pressure value is the absolute value of the difference value of the first air duct static pressure value and the second air duct static pressure value. Of course, the variation of the first duct static pressure value relative to the second duct static pressure value may be the ratio of the first duct static pressure value to the second duct static pressure value, etc., and such flexible adjustment and variation without departing from the principle and scope of the present invention should be limited within the protection scope of the present invention.
Preferably, as shown in fig. 2, the debugging method of the present invention further includes: if the variation value of the first air duct static pressure value relative to the second air duct static pressure value is larger than the preset value, the indoor fan is enabled to operate at a third preset rotating speed, and a third duty ratio of the indoor fan is obtained; acquiring a third air duct static pressure value according to a third duty ratio of the indoor fan; comparing the change value of the first air duct static pressure value relative to the third air duct static pressure value and the change value of the second air duct static pressure value relative to the third air duct static pressure value with preset values; and selectively determining the current air duct static pressure value according to the first air duct static pressure value, the second air duct static pressure value and the third air duct static pressure value according to the comparison result, wherein the second preset rotating speed is less than the third preset rotating speed. Under the condition that the variation value of the first air duct static pressure value relative to the second air duct static pressure value is larger than the preset value, the error of the first air duct static pressure value may be larger, the error of the second air duct static pressure value may also be larger, and the errors of the first air duct static pressure value and the second air duct static pressure value may be larger or smaller. The variation value of the first air duct static pressure value relative to the third air duct static pressure value is the absolute value of the difference value of the first air duct static pressure value and the third air duct static pressure value, and the variation value of the second air duct static pressure value relative to the third air duct static pressure value is the absolute value of the difference value of the second air duct static pressure value and the third air duct static pressure value. Of course, the variation value of the first air duct static pressure value relative to the third air duct static pressure value may also be the ratio of the first air duct static pressure value to the third air duct static pressure value, the variation value of the second air duct static pressure value relative to the third air duct static pressure value may also be the ratio of the second air duct static pressure value to the third air duct static pressure value, and the like, and such flexible adjustment and variation do not depart from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.
Preferably, as shown in fig. 2, the step of "selectively determining the current air duct static pressure value according to the first air duct static pressure value, the second air duct static pressure value, and the third air duct static pressure value according to the comparison result" specifically includes: and if only the variation value of the first air duct static pressure value relative to the third air duct static pressure value is not larger than the preset value, taking the average value of the first air duct static pressure value and the third air duct static pressure value as the current air duct static pressure value. When only the variation value of the first air duct static pressure value relative to the third air duct static pressure value is not larger than the preset value, namely the variation value of the first air duct static pressure value relative to the third air duct static pressure value is not larger than the preset value, but the variation value of the second air duct static pressure value relative to the third air duct static pressure value is larger than the preset value, the first air duct static pressure value is closer to the third air duct static pressure value, and the second air duct static pressure value is larger than the third air duct static pressure value.
Preferably, as shown in fig. 2, the step of "selectively determining the current air duct static pressure value according to the first air duct static pressure value, the second air duct static pressure value, and the third air duct static pressure value according to the comparison result" specifically includes: and if only the variation value of the second air duct static pressure value relative to the third air duct static pressure value is not larger than the preset value, taking the average value of the second air duct static pressure value and the third air duct static pressure value as the current air duct static pressure value. When only the variation value of the second air duct static pressure value relative to the third air duct static pressure value is not larger than the preset value, namely the variation value of the second air duct static pressure value relative to the third air duct static pressure value is not larger than the preset value, but the variation value of the first air duct static pressure value relative to the third air duct static pressure value is larger than the preset value, the second air duct static pressure value is closer to the third air duct static pressure value, and the difference between the first air duct static pressure value and the third air duct static pressure value is larger.

When the variation of the first air duct static pressure value relative to the third air duct static pressure value and the variation of the second air duct static pressure value relative to the third air duct static pressure value are not greater than the preset values, it is indicated that the first air duct static pressure value and the third air duct static pressure value are relatively close, the second air duct static pressure value and the third air duct static pressure value are also relatively close, but the first air duct static pressure value and the second air duct static pressure value have a large difference, in this case, most likely, the error of the third air duct static pressure value is small, the error of the first air duct static pressure value and the second air duct static pressure value is small, but the deviation direction of the first air duct static pressure value and the second air duct static pressure value is opposite, for example, the first air duct static pressure value may be smaller than the third air duct static pressure value, the second air duct static pressure value is larger than the third air duct static pressure value, so that the first air duct static pressure value and the second air duct static pressure value have a large difference, and at the moment, taking the average value of the first air duct static pressure value, the second air duct static pressure value and the third air duct static pressure value as the current air duct static pressure value.
It should be noted that, if the variation value of the first air duct static pressure value relative to the third air duct static pressure value and the variation value of the second air duct static pressure value relative to the third air duct static pressure value are both greater than the preset values, it is indicated that the difference between the first air duct static pressure value and the third air duct static pressure value is relatively large, the difference between the second air duct static pressure value and the third air duct static pressure value is also relatively large, and in this case, it is most likely that the errors of the first air duct static pressure value, the second air duct static pressure value and the third air duct static pressure value are relatively large, and at this time, the average value of the first air duct static pressure value, the second air duct static pressure value and the third air duct static pressure value is not used as the air duct static pressure value, that is, the first air duct static pressure value, the second air duct static pressure value and the third air duct static pressure value are all discarded.
