fig. 1 is a flowchart of a temperature compensation control method according to an embodiment of the invention.
Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Thus, a feature indicated in this specification will serve to explain one of the features of one embodiment of the invention, and does not imply that every embodiment of the invention must have the stated feature. Further, it should be noted that this specification describes many features. Although some features may be combined to show a possible system design, these features may also be used in other combinations not explicitly described. Thus, the combinations illustrated are not intended to be limiting unless otherwise specified.
The principles of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in fig. 1, the air conditioner temperature compensation control method of the present invention is mainly applied to a cooling mode, and if the humidity conditions in the room are different in the cooling mode, the same user sets the temperature, so that different experience feelings will be brought to the user, and the user needs to manually adjust the temperature again to meet certain comfort level.
According to the air conditioner temperature compensation control method, when the air conditioner is in a refrigeration mode, indoor environment temperature and indoor environment humidity are collected through arranging a plurality of sensors, if the current indoor environment temperature is lower than the temperature set by a user, the current indoor environment humidity is processed at intervals of preset time length to judge whether the current target temperature needs to be adjusted according to the processed real-time indoor environment humidity, and if the processed real-time indoor environment humidity meets preset conditions, the current target temperature is adjusted according to a preset threshold corresponding to the conditions.
In this embodiment, processing the collected real-time indoor environment humidity specifically includes calculating real-time absolute humidity of the real-time indoor environment humidity, and calculating real-time absolute humidity according to the current indoor environment temperature and the current indoor environment humidity, where the formula specifically adopted is:
(ii) a Where d is the real-time absolute humidity, ψ is the real-time indoor ambient humidity detected by the humidity sensor, and T is the current indoor ambient temperature detected by the temperature sensor.
The manufacturer of the air conditioner can obtain a threshold value of absolute humidity with small influence on indoor temperature in advance according to experimental data, preset corresponding preset absolute humidity in the air conditioner, and adjust the target temperature of the current air conditioner according to different conditions if the difference value of the preset absolute humidity obtained by calculation of the air conditioner minus the real-time absolute humidity meets the preset condition corresponding to the difference value. And if the difference value obtained by subtracting the real-time absolute humidity from the preset absolute humidity does not meet the corresponding preset condition, not adjusting the target temperature of the air conditioner.
Specifically, when the difference between the real-time absolute humidity and the preset absolute humidity calculated by the air conditioner is greater than or equal to the first difference preset value, the current target temperature is subtracted by the first temperature threshold value to obtain a new current target temperature, and the air conditioner operates at the new current target temperature, but the target temperature displayed to the user by the air conditioner is always the user-set temperature and cannot be changed due to automatic adjustment of the air conditioner. And when the difference value obtained by subtracting the real-time absolute humidity from the preset absolute humidity calculated by the air conditioner is smaller than a second difference value preset value, adding a second temperature threshold value to the current target temperature to obtain a new current target temperature, wherein the air conditioner operates at the new current target temperature, and the target temperature displayed by the air conditioner is still the temperature set by the user.
For example, in a specific application embodiment, the preset absolute humidity set by the air conditioner manufacturer is defined as d1, and the real-time absolute humidity calculated by the air conditioner is defined as d2, and if the temperature is set to 25 ℃ by the user and the relative humidity reference value considered by the manufacturer to have a small influence on the temperature is 45%, the preset absolute humidity d1=8.89 g/kg having a small influence on the temperature can be obtained through experimental data. And calculating real-time absolute humidity d2 by the air conditioner at intervals, and calculating the difference delta d = d 1-d 2 of the absolute humidity.
On the premise that the current indoor environment temperature is lower than the set temperature of the user, when the difference delta d is calculated for 1min continuously and is larger than or equal to 0.3, the target temperature of the air conditioner is compensated to be minus 0.5 ℃, namely the current target temperature is subtracted by 0.5 ℃, and then the air conditioner continues to operate at the new target temperature. The values of 0.3, -0.5, etc. listed in this specific application example are specific examples, and those skilled in the art may adjust the setting according to the local climate, and if the current target temperature reaches the lower limit of the control target, the air conditioner stops adjusting the current target temperature.
On the premise of meeting the condition that the current indoor environment temperature is lower than the temperature set by the user, when the calculation result delta d is less than-0.3 in 1min continuously, the target temperature of the air conditioner is compensated by +0.1 ℃, namely the current target temperature is added with 0.1 ℃, and then the air conditioner continues to operate at the new target temperature. The values of-0.3, 0.1, etc. listed in this specific application example are a specific example, and those skilled in the art may set the current target temperature according to the local climate adjustment, and when the current target temperature reaches the upper limit of the control target, the air conditioner stops adjusting the current target temperature.
In one embodiment, the control target lower limit may be 16 ℃ and the control target upper limit may be 28 ℃.
On the basis, when the difference value obtained by subtracting the real-time absolute humidity from the preset absolute humidity calculated by the air conditioner is larger than or equal to the first difference value preset value, the air conditioner can be further controlled to operate at the lowest wind level while the air conditioner operates at the new current target temperature while the target temperature is adjusted, and the user experience is more comfortable.
If the difference value of the real-time absolute humidity subtracted from the preset absolute humidity calculated by the air conditioner is greater than or equal to the second difference preset value and smaller than the first difference preset value, the air conditioner operates at the current target temperature, namely when delta d is greater than or equal to minus 0.3 and less than 0.3, the air conditioner operates at the current target temperature which is set by a user.
If the current indoor environment temperature detected by the air conditioner is greater than the user set temperature, the air conditioner is operated with the user set temperature as the target temperature.
The invention also protects the air conditioner adopting the temperature compensation control method, the air conditioner controller, the humidity sensor for detecting the real-time indoor environment humidity and the temperature sensor for detecting the real-time indoor environment temperature, and the specific temperature sensor and the specific humidity sensor can be arranged indoors or at the air return opening. And when the controller is in a refrigeration mode, the controller receives detection results of the temperature sensor and the humidity sensor, so that the temperature control is realized by the air conditioner temperature compensation control method.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
