Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Considering that the air conditioner has poor heating effect and affects the comfort under the working conditions of medium and high outdoor temperature, the embodiment provides a method for controlling the comfort of the air conditioner. When the air conditioner operates in a heating mode in a medium-temperature environment or a high-temperature environment, the air conditioner can provide the maximum heating quantity on the premise of ensuring the reliability, and the indoor environment temperature is quickly increased.
The comfort control method of the air conditioner provided by the embodiment can judge whether to start the high-temperature heating mode according to the outdoor side environment temperature, and adjust the frequency of the compressor according to the classification definition of the inner disc temperature. Specifically, the inner disc temperature of the air conditioner can be used as a judgment basis for adjusting the frequency of the compressor, and the accurate adjustment of the frequency of the compressor is realized by combining the change of the inner disc temperature.
Fig. 1 is a schematic flow chart of an air conditioner comfort control method in an embodiment of the present invention, the method including:
and S102, acquiring the temperature of the inner disc in the heating mode.
The air conditioner runs in a heating mode after being started, and the temperature of the inner disc of the air conditioner is obtained after the air conditioner stably runs for 5 minutes.
And S104, if the temperature of the inner disc is smaller than the first temperature threshold of the inner disc, acquiring the temperature of the inner ring.
The specific value of the first inner plate temperature threshold can be a corresponding temperature value under the condition that the air conditioner is in an ultrahigh load at present under the working state of the air conditioner.
If the temperature of the inner plate is smaller than the threshold value, the air conditioner has a space for partially increasing the load, and whether the load is continuously increased or not can be judged and determined according to the subsequent steps. If the temperature of the inner disc is greater than or equal to the first inner disc temperature threshold value, the air conditioner works in an ultrahigh load state, and at the moment, the compressor is controlled to reduce the third frequency, so that the running reliability of the air conditioner is ensured, and the frequency is reduced in time to ensure that the unit is not damaged.
And S106, controlling the frequency of the compressor to be increased according to the inner ring temperature, the change trend of the inner disc temperature and the difference value between the inner ring temperature and the inner ring set temperature.
Based on the temperature of the inner ring, whether the current indoor environment temperature is in the temperature range in which the user feels comfortable can be determined, if the current indoor environment temperature is in the temperature range in which the user feels comfortable, the compressor is controlled to continue to operate stably, if the current indoor environment temperature is lower than the temperature range in which the user feels comfortable, the possibility of improving the frequency of the compressor exists, and the change trend of the temperature of the inner disc and the difference value between the temperature of the inner ring and the set temperature of the inner ring can be further considered.
The variation trend of the inner plate temperature generally comprises an ascending trend, a constant trend and a descending trend, wherein the ascending trend indicates that the heating capacity of the air conditioner is continuously increased, the constant trend indicates that the heating capacity of the air conditioner is maintained at a certain level, and the descending trend indicates that the heating capacity of the air conditioner is continuously reduced. Because the temperature of the inner ring is lower than the temperature range of comfortable body feeling, the heating capacity needs to be increased as much as possible to meet the requirements of users, under the condition of the rising trend, the compressor is controlled to continue to stably operate, under the unchanging trend and the falling trend, the frequency of the compressor is possibly increased, and the difference between the temperature of the inner ring and the set temperature of the inner ring can be further considered.
Generally, the inner ring set temperature set by the user is the user expected ideal temperature, in the above judgment process, even if the inner ring temperature is lower and the variation trend of the inner disc temperature is the invariable trend, if the current inner ring temperature is close to the inner ring set temperature set by the user, it indicates that the current inner ring temperature basically meets the user expectation, and in this case, the heating capacity does not need to be increased any more, and the compressor is controlled to continue to operate stably; if the difference between the current inner ring temperature and the inner ring set temperature set by the user is large, the compressor needs to be controlled to increase the frequency.
And after the compressor is controlled to run for a preset time after the frequency rising, the steps of obtaining the inner disc temperature, obtaining the inner ring temperature and controlling the frequency rising of the compressor in the steps S102-S106 are repeatedly executed.
According to the air conditioner comfort control method provided by the embodiment of the invention, the inner disc temperature of the air conditioner can be used as the adjusting basis of the frequency of the compressor, and the accurate frequency increasing of the compressor is realized by combining the inner ring temperature, the variation trend of the inner disc temperature and the difference value of the inner ring temperature and the set temperature of the inner ring, so that the heating effect of the air conditioner is improved.
Considering the need for precise adjustment of the compressor frequency, the above S106 may be performed according to the following steps:
firstly, if the inner ring temperature is smaller than the inner ring temperature threshold, calculating the difference value between the current value of the inner disc temperature and the historical value before the preset time interval. And if the inner ring temperature is greater than or equal to the inner ring temperature threshold, controlling the compressor to continuously run at the current frequency. The inner ring temperature threshold value ranges from 20 or more to 32 or less, for example 25.
And secondly, if the difference value between the current value and the historical value is smaller than a first temperature difference threshold value, calculating the difference value between the temperature of the inner ring and the set temperature of the inner ring. If the result of subtracting the historical value from the current value is a positive value, the temperature of the inner disc rises, namely the inner disc is in a rising trend; if the result of subtracting the historical value from the current value is 0, the current value is in an unchanged trend; if the result of subtracting the historical value from the current value is a negative value, the temperature of the inner disc is falling, namely in a descending trend.
By calculating the change of the temperature of the inner disc along with the time, whether the system load and the pressure rise or not can be judged. And under the condition that the difference value is smaller than the first temperature difference threshold value, corresponding to the invariant trend and the descending trend, continuously judging the difference value between the temperature of the inner ring and the set temperature of the inner ring. And if the difference value between the current value and the historical value is larger than or equal to the first temperature difference threshold value, controlling the compressor to continuously run at the current frequency. The first temperature difference threshold value ranges from 0 to 5, for example, 2.
And then, if the difference value between the temperature of the inner ring and the set temperature of the inner ring is greater than or equal to a second temperature difference threshold value, controlling the compressor to increase the frequency.
By calculating the difference between the inner ring temperature and the inner ring set temperature, whether the current heating meets the requirements of users can be judged. And if the difference value between the temperature of the inner ring and the set temperature of the inner ring is smaller than a second temperature difference threshold value, controlling the compressor to continuously run at the current frequency. The second temperature difference threshold value ranges from 0 to 5, for example, 2.
The determination process of the inner ring temperature, the trend of the inner disc temperature, and the difference between the inner ring temperature and the inner ring set temperature may be performed in the above order, or may be performed after the three are exchanged in order.
Considering that the temperature of the inner disk is different, the corresponding air conditioner loads are different, so that the upgradable spaces of the compressors are different, the higher the temperature of the inner disk is, the smaller the corresponding upgradable space is, and the lower the temperature of the inner disk is, the larger the corresponding upgradable space is. Based on this, the step of controlling the compressor to increase frequency may be performed according to the following steps:
if the temperature of the inner disc is smaller than the first inner disc temperature threshold and is larger than or equal to the second inner disc temperature threshold, controlling the compressor to increase the first frequency; and if the temperature of the inner disc is less than the second inner disc temperature threshold value, controlling the compressor to increase the second frequency.
Wherein the second frequency is greater than the first frequency. Because the corresponding frequency-raising spaces of different inner disk temperatures are different, the raising frequency value is different when the compressor is actually controlled to raise the frequency. Optionally, a value range of the first inner disc temperature threshold is greater than or equal to 59 and less than or equal to 65, and a value range of the first inner disc temperature threshold is greater than or equal to 50 and less than or equal to 58.
