Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A proposed air conditioner control method according to an embodiment of a first aspect of the present invention is described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of an air conditioning control method according to an embodiment of the present invention, as shown in fig. 2, the air conditioning control method including:
and S1, executing a start-stop control instruction according to the difference value between the current indoor temperature and the set temperature and the start-stop temperature difference threshold value.
The current indoor temperature can be detected through the temperature sensor, and the required temperature, namely the set temperature, is set through the remote controller or the wire controller or the control panel. When the air conditioner operates, the indoor temperature is gradually close to the set temperature and is finally in the set temperature range so as to meet the requirements of users.
It should be noted that, in the embodiment of the present invention, the start-stop control may include start-stop control on the indoor unit or start-stop control on only the outdoor unit, but the start-stop control instruction is usually sent by a control module of the indoor unit. The indoor unit can be normally stopped to continue running only by controlling the starting and stopping of the outdoor unit under the starting and stopping control instruction sent by the indoor unit.
Specifically, if the difference between the current indoor temperature and the set temperature is greater than or equal to the start-stop temperature difference threshold value to execute the start control instruction, namely the difference between the current indoor temperature and the set temperature is larger, the air conditioner operates to continue to regulate the indoor air temperature; and if the difference value between the current indoor temperature and the set temperature is smaller than the start-stop temperature difference threshold value, executing a stop control instruction, namely the indoor temperature is basically in the set temperature range, and the set requirement of a user is met, and suspending temperature adjustment. The circulation is carried out, and the indoor temperature is maintained to meet the requirement of the temperature set by the user.
And S2, recording the frequency of executing the start-stop control command.
Specifically, as explained above, during operation, the indoor unit continuously outputs the start-stop control command according to the relationship between the difference value between the indoor temperature and the set temperature and the start-stop temperature difference threshold value. In the embodiment of the present invention, the number of times that the indoor unit executes the start-stop control instruction within a period of time may be recorded, for example, the number of start-stops per hour, that is, the start-stop frequency, may be recorded.
If the execution is opened and is stopped very frequently and open the frequency of stopping promptly great, will cause the frequent fluctuation of indoor temperature, influence the travelling comfort, still can reduce the life of part spare part, to under the refrigeration mode, especially at the low load operation and when dehumidification demand and indoor temperature change are easier, the air conditioner frequently opens and stops and makes the dehumidification function intermittent and intermittent, the dehumidification effect is not good or even the function is lost, perhaps, to the nevertheless high dehumidification requirement of low refrigeration cooling demand, frequently open and stop will influence the dehumidification effect greatly.
And S3, adjusting the temperature difference threshold according to the frequency of executing the start-stop control instruction.
In order to avoid the problem caused by frequent start-stop, in the embodiment of the invention, the start-stop temperature difference threshold is adjusted according to the frequency of executing the start-stop control instruction. For example, when the frequency of executing the start-stop control instruction is high, that is, the indoor temperature changes significantly, that is, the difference between the indoor temperature and the set temperature changes rapidly, so that the indoor unit frequently executes the start-stop control instruction, the start-stop temperature difference threshold is increased, which is equivalent to phase-changing prolonging the time for the difference between the indoor temperature and the set temperature to reach the start-stop temperature difference threshold, that is, reducing the frequency of executing the start-stop control instruction by the indoor unit.
Specifically, in the embodiment of the present invention, if the frequency of executing the start-stop control instruction reaches the frequency limit, it is considered that the start-stop is frequent, and the start-stop temperature difference threshold is increased. For example, if the frequency of executing the start-stop control command is greater than or equal to the first frequency limit value, it is considered that the start-stop is very frequent, which causes large fluctuation of the indoor temperature, or poor dehumidification effect, which affects comfort, the start-stop temperature difference threshold value is increased by a first correction value, so as to appropriately reduce the start-stop frequency; and if the frequency of executing the start-stop control instruction is greater than or equal to the second frequency limit value and less than the first frequency limit value, the start-stop is considered to be frequent, the indoor temperature fluctuates, or the dehumidification effect is poor, the start-stop temperature difference threshold is increased by a second correction value, wherein the second correction value is less than the first correction value, so that the start-stop frequency is properly reduced.
Further, if the frequency of executing the start-stop control instruction is greater than or equal to the third frequency limit and less than the second frequency limit after the start-stop temperature difference threshold is adjusted, and the influence of the start-stop frequency on comfort is considered not to be great, the adjusted start-stop temperature difference threshold is maintained, that is, the current correction is maintained.
It can be understood that if the frequency of the start-stop control instruction executed by the indoor unit is less than the fourth frequency limit value, and the fourth frequency limit value is less than the third frequency limit value, the comfort of the indoor temperature and humidity is hardly affected or the influence on parts is not great, and the start-stop temperature difference threshold value is not adjusted.
It should be noted that, the above embodiment is an example of adjusting the start-stop temperature difference threshold according to the start-stop frequency, and the start-stop temperature difference threshold is not limited to the frequency limit interval set above, and may be set as needed, for example, increasing the limit judgment interval and performing more detailed adjustment on the start-stop temperature difference threshold.
And (4) continuously carrying out the steps to circularly judge the starting and stopping frequency until a stopping command is received, and stopping the air conditioner according to the control requirement.
In summary, the air conditioner control method according to the embodiment of the present invention obtains system information such as set temperature and operating conditions, obtains information of an indoor unit executing a start/stop control instruction, and adjusts a start/stop temperature difference threshold according to a frequency of the indoor unit executing the start/stop control instruction, so as to appropriately reduce start/stop frequency, reduce fluctuation of indoor temperature, facilitate stable control of indoor temperature, avoid loss of a dehumidification function due to frequent start/stop in a cooling mode, improve comfort, reduce influence of frequent start/stop on service life of components, and improve reliability.

Therefore, the starting and stopping frequency can be properly reduced, and the influence of frequent starting and stopping on indoor temperature and humidity and parts is reduced.
