In the related art, when the air conditioner is operated in a heating mode under a high-temperature working condition, the operation frequency of the compressor is unreasonable to control, and the reliability and the heating effect of the heating operation cannot be considered.
Disclosure of Invention
In order to solve the problems that the running frequency of a compressor is unreasonable to control and the heating running reliability and the heating effect cannot be considered when the air conditioner is in heating running under the high-temperature working condition, the invention provides a control method of the air conditioner, which comprises the following steps: heating and starting up the air conditioner; acquiring the starting time of a compressor; and determining the upper limit value of the running frequency of the compressor according to the size relation between the starting time length of the compressor and the time length threshold value.

In this embodiment, the determining the upper limit value of the operating frequency of the compressor according to the relationship between the compressor on-time and the time threshold includes: determining the upper limit value of the running frequency of the compressor according to the outdoor environment temperature under the condition that the starting time of the compressor is less than the time threshold; and setting the upper limit value of the running frequency of the compressor as a first upper limit value of the frequency under the condition that the starting time of the compressor is greater than or equal to the time threshold.
The technical effect achieved after the technical scheme is adopted is as follows: if the starting time of the compressor is less than the time threshold, the compressor of the air conditioner is just started to heat, the high-pressure of the system is instantly increased, the temperature of the coil of the indoor heat exchanger is gradually increased, namely the air conditioner is in a starting unsteady state currently, so that the operating frequency of the compressor is limited by determining the upper limit value of the operating frequency of the compressor through the outdoor environment temperature, and the problem that the temperature of the coil of the indoor evaporator cannot be protected and reduced in frequency in time is solved; if the compressor starting time is greater than or equal to the time threshold, the air conditioner is indicated to be in heating operation for a period of time, that is, the air conditioner is currently in a heating stable operation state, and if the control method of limiting the operation frequency of the compressor by the outdoor environment temperature is continuously adopted, the problem that the indoor heating requirement cannot be met even if the operation frequency of the compressor is started to the maximum operation frequency allowed by the compressor can occur. In order to ensure the normal operation heating process of the air conditioner and enable the air conditioner to continuously provide heat for the indoor space, when the air conditioner is in a heating stable operation state, a control method of limiting the operation frequency of the compressor by the outdoor environment temperature is not adopted any more.

When the outdoor environment temperature is higher, the operation frequency of the compressor can be reduced by setting a lower upper limit value of the operation frequency of the compressor, so that the problem that the heating operation reliability of the air conditioner is influenced because the air conditioner operates under overhigh pressure for a long time is solved.

[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1, a flowchart of a control method of an air conditioner according to a first embodiment of the present invention is shown. The control method of the air conditioner comprises the following steps: heating and starting up the air conditioner; acquiring the starting time of a compressor; and determining the upper limit value of the running frequency of the compressor according to the size relation between the starting time length of the compressor and the time length threshold value.
It can be understood that after the air conditioner is heated and started, the heating operation stage where the air conditioner is currently located can be accurately judged according to the size relationship between the starting time length of the compressor and the time length threshold value, so that the upper limit value of the corresponding compressor operation frequency can be set according to the heating operation stage where the air conditioner is currently located, the compressor operation frequency is reasonably controlled, and the contradiction between the heating operation reliability and the heating effect of the air conditioner is further solved.
Further, the determining the upper limit value of the operating frequency of the compressor according to the relationship between the compressor starting time and the time threshold value includes: determining the upper limit value of the running frequency of the compressor according to the outdoor environment temperature under the condition that the starting time of the compressor is less than the time threshold; and setting the upper limit value of the running frequency of the compressor as a first upper limit value of the frequency under the condition that the starting time of the compressor is greater than or equal to the time threshold.
In a specific embodiment, if the starting time of the compressor is less than the time threshold, it indicates that the compressor of the air conditioner is just started to heat, at this time, the high-pressure of the system is instantly increased, the temperature of the coil of the indoor heat exchanger is gradually increased, that is, the air conditioner is currently in a starting unsteady state stage, so that the operating frequency of the compressor is limited by determining the upper limit value of the operating frequency of the compressor through the outdoor environment temperature, and the problem that the temperature of the coil of the indoor evaporator cannot be protected and reduced in frequency in time is solved; if the compressor starting time is greater than or equal to the time threshold, the air conditioner is indicated to be in heating operation for a period of time, that is, the air conditioner is currently in a heating stable operation state, and if the control method of limiting the operation frequency of the compressor by the outdoor environment temperature is continuously adopted, the problem that the indoor heating requirement cannot be met even if the operation frequency of the compressor is started to the maximum operation frequency allowed by the compressor can occur. In order to ensure the normal operation heating process of the air conditioner and enable the air conditioner to continuously provide heat for the indoor space, when the air conditioner is in a heating stable operation state, a control method that the outdoor environment temperature limits the operation frequency of the compressor is not adopted.
Further, the upper limit value of the operating frequency of the compressor is inversely related to the outdoor ambient temperature.
It can be understood that, when the air conditioner is operated in a high-temperature working condition, the heating operation reliability of the air conditioner is more easily affected as the outdoor environment temperature is higher, so that the upper limit value of the operation frequency of the compressor is set to be negatively related to the outdoor environment temperature, so as to ensure the heating operation reliability of the air conditioner. When the outdoor environment temperature is higher, the operation frequency of the compressor can be reduced by setting a lower upper limit value of the operation frequency of the compressor, so that the problem that the heating operation reliability of the air conditioner is influenced because the air conditioner operates under overhigh pressure for a long time is solved.
Further, with reference to fig. 2, the determining the upper limit value of the operating frequency of the compressor according to the outdoor ambient temperature includes: if T Outer ring ＜T 11 Setting the upper limit value of the running frequency of the compressor to be F 0 (ii) a If T 11 ≤T Outer ring ＜T 12 Setting the upper limit value of the running frequency of the compressor to be F 1 (ii) a If T 12 ≤T Outer ring ＜T 13 Setting the upper limit value of the running frequency of the compressor to be F 2 (ii) a If T 13 ≤T Outer ring ＜T 14 Then setting the upper limit value of the running frequency of the compressor to be F 3 (ii) a If T 14 ≤T Outer ring Setting the upper limit value of the running frequency of the compressor to be F 4 (ii) a Wherein, T Outer ring Is the outdoor ambient temperature; t is 11 Is a first outer loop temperature threshold; t is 12 Is a second outer loop temperature threshold; t is 13 Is a third outer loop temperature threshold; t is a unit of 14 Is a fourth outer ring temperature threshold; f 0 Is a first frequency upper limit value; f 1 Is a second frequency upper limit value; f 2 A third frequency upper limit value; f 3 Is a fourth frequency upper limit value; f 4 Is a fifth frequency upper limit value; t is 11 ＜T 12 ＜T 13 ＜T 14 ；F 0 ＞F 1 ＞F 2 ＞F 3 ＞F 4 。
It can be understood that by setting a plurality of outer ring temperature threshold values, the outdoor environment temperature is divided into a plurality of outdoor environment temperature intervals, and corresponding compressor operation frequency upper limit values are set according to the outdoor environment temperature intervals, so that the accurate control of the compressor operation frequency can be realized, the air conditioner is more timely in protection of the heating operation reliability, and the protection effect is better.
Further, with reference to fig. 3, the method for controlling an air conditioner further includes: acquiring the temperature of an indoor coil; controlling the running state of a compressor according to the temperature of the indoor coil pipe; wherein the operation state of the compressor includes: the compressor stops running and \ or the running frequency of the compressor is reduced and \ or the ascending frequency of the compressor is prohibited and \ or the normal control of the running frequency of the compressor is recovered.
It can be understood that, when the air conditioner is in stable operation during heating, the system high pressure of the air conditioner can be estimated according to the temperature of the indoor coil, so that the operation state of the air conditioner can be adjusted in time according to the temperature of the indoor coil, and the heating effect of the air conditioner is improved on the basis of ensuring the reliability of heating operation.
Further, the controlling the operation state of the compressor according to the temperature of the indoor coil comprises: if T 21 ≤T Inner disc Controlling the compressor to stop running; if T 22 ≤T Inner disc ＜T 21 Reducing the running frequency of the compressor; if T 23 ≤T Inner disc ＜T 22 If yes, the frequency rising of the compressor is forbidden; wherein, T 21 Is a first inner disc temperature threshold; t is 22 Is a second inner disc temperature threshold; t is 23 Is a third inner disc temperature threshold; t is 23 ＜T 22 ＜T 21 。
In one embodiment, if T 21 ≤T Inner disc If the temperature of the indoor coil is extremely high, namely the high pressure of the system is extremely high and exceeds the range which can be borne by the air conditioner, the compressor is controlled to stop running; if T 22 ≤T Inner disc ＜T 21 If the temperature of the indoor coil is higher, namely the system high-pressure is higher, but still in the range that the air conditioner can bear, the system high-pressure is reduced by reducing the operation frequency of the compressor, so that the heating operation reliability of the air conditioner is ensured; if T 23 ≤T Inner disc ＜T 22 It indicates that the current indoor coil temperature, i.e. the system high pressure, is slightly higher, so the compressor is prohibited from increasing frequency. For example, the reduction rate of the operating frequency of the compressor is AHz/Bs.
Further, the controlling the operation state of the compressor according to the temperature of the indoor coil further comprises: if T Inner disc ＜T 23 Regular control of the compressor operating frequency is resumed.
In one embodiment, if T Inner disc ＜T 23 And then, the current indoor coil temperature, namely the high-pressure of the system is normal, and the high-pressure is not required to be reduced by reducing the running frequency of the compressor, so that the conventional control of the running frequency of the compressor is recovered.
Further, in the case of recovering the conventional control of the compressor operation frequency, the compressor operation frequency cannot exceed the compressor operation frequency upper limit value.
It can be understood that even if the conventional control of the operation frequency of the compressor is resumed, the operation frequency of the compressor is appropriately increased according to the indoor heating demand on the basis of ensuring the reliability of the heating operation of the air conditioner, and the heating efficiency cannot be increased without neglecting the reliability of the heating operation of the air conditioner.
