First embodiment
The embodiment of the invention provides a mute control method which is used for determining the time for the air conditioner 1 to automatically enter a mute mode according to the outdoor environment temperature and adjusting the maximum running frequency of a compressor and the maximum allowable running rotating speed of a fan according to the actual situation during the mute mode. Please refer to fig. 2, which is a flowchart illustrating a mute control method according to an embodiment of the present invention. The mute control method comprises the following steps:
step S201: and acquiring the outdoor ambient temperature according to a preset first time interval in a preset period.
In a preferred embodiment, the predetermined period is 24 hours and the first time interval is 30 minutes. That is, the outdoor ambient temperature was acquired every 30 minutes in a cycle of 24 hours, thereby obtaining 48 outdoor ambient temperatures.
The advantage of using 24 hours as the predetermined period is that the change of the ambient temperature outside the chamber during a day can be captured.
It should be noted that the first time interval may be modified according to actual requirements, and may be other values, which are not limited herein.
Step S202: and recording first acquisition time corresponding to the minimum outdoor environment temperature in all the outdoor environment temperatures acquired in a preset period.
It is understood that the time of day at which the outdoor ambient temperature is lowest is obtained. Generally, the moment when the outdoor ambient temperature is lowest is usually at midnight, the moment when the user is at rest.
Please refer to fig. 3, which is a flowchart illustrating the step S202. The step S202 includes:
substep S2021: according to a predetermined formula
Figure BDA0001690363120000071
A minimum outdoor ambient temperature is obtained.
Here, Tao1 is the minimum outdoor ambient temperature, and Tao is the outdoor ambient temperature at the present time.
It should be noted that, the first obtained outdoor environment temperature is used as a comparison value, and each subsequent outdoor environment temperature is obtained and compared with the comparison value, if the outdoor environment temperature at the current time is less than the comparison value, the outdoor environment temperature at the current time is updated to a new comparison value, and after comparing all the outdoor environment temperatures obtained within 24 hours, the final comparison value is used as the minimum outdoor environment temperature.
Substep S2022: and recording the first acquisition time corresponding to the minimum outdoor environment temperature.
By recording the first acquisition time corresponding to the minimum outdoor environment temperature, the time of day at which the outdoor environment temperature is the lowest can be obtained.
Step S203: a mute mode period is determined according to the first acquisition time.
Since the first collection time is the time of the lowest temperature in the day, and in general, the time of the lowest temperature in the day is mostly at midnight, and at this time, the time of the rest of the user is the time of the rest of the user, the mute mode time period is determined based on the first collection time, and the mute mode time period can be more suitable for the rest time of the user.
Specifically, a difference between the first acquisition time and the first threshold is taken as a first endpoint, a sum of the first acquisition time and the first threshold is taken as the first endpoint, and a time greater than or equal to the first endpoint and less than or equal to the first endpoint is determined as the silent mode period.
Let the first acquisition time be t1With the first threshold value q and the second threshold value p, the mute mode period t ∈ [ t [ [ t ]1-q,t1+p]。
In a preferred embodiment, the first threshold value q is 4 and the second threshold value p is 3. In other embodiments, the first threshold q and the second threshold p may be modified according to the actual requirement of the user, and are not limited herein.
Step S204: the silent mode is automatically entered during a silent mode period.
Step S205: and acquiring the indoor ambient temperature according to a preset second time interval.
After the air conditioner 1 enters the silent mode, the indoor ambient temperature is acquired every second time interval to determine the change trend of the indoor ambient temperature, so that the refrigerating effect or the heating effect of the air conditioner 1 after entering the silent mode can be conveniently judged.
Step S206: the operation mode of the air conditioner 1 is acquired.
It is determined whether the air conditioner 1 is in the cooling mode or in the heating mode.
Step S207: and adjusting the operating parameters of the air conditioner 1 according to a plurality of indoor ambient temperatures and the operation modes at a preset third time interval.
Please refer to fig. 4, which is a flowchart illustrating the step S207. The step S207 includes:
substep S2071: and acquiring the difference value of the two adjacent indoor environment temperatures according to a preset third time interval.
It can be understood that, every preset third time interval, the difference between two adjacent indoor ambient temperatures in the current state is obtained to determine the variation trend of the indoor ambient temperatures.
Substep S2072: and when the air conditioner 1 is in the cooling mode and the difference value is smaller than the third threshold value, improving the maximum running frequency of the compressor of the air conditioner 1 and the maximum rotating speed of the fan.
When the air conditioner 1 is in the cooling mode, if the difference is smaller than the third threshold, it indicates that the current compressor operating frequency and the maximum fan rotating speed of the air conditioner 1 at this time may not meet the cooling requirement of the air conditioner 1, so that the maximum compressor operating frequency and the maximum fan rotating speed of the air conditioner 1 are increased to meet the requirement of a user.
It should be noted that, when the air conditioner 1 is in the cooling mode and the difference is greater than or equal to the third threshold, the current maximum operating frequency of the compressor and the maximum rotational speed of the fan are kept unchanged.
Substep S2073: and when the air conditioner 1 is in a heating mode and the difference value is greater than a fourth threshold value, improving the maximum operation frequency of a compressor and the maximum rotating speed of a fan of the air conditioner 1.
When the air conditioner 1 is in the heating mode, if the difference is greater than the fourth threshold, it indicates that the current compressor operating frequency and the maximum fan rotating speed of the air conditioner 1 at the moment may not meet the heating requirement of the air conditioner 1, so that the maximum compressor operating frequency and the maximum fan rotating speed of the air conditioner 1 are increased to meet the requirement of a user.
It should be noted that, when the air conditioner 1 is in the heating mode and the difference is less than or equal to the third threshold, the current maximum operating frequency of the compressor and the maximum rotation speed of the fan are kept unchanged.
It should be noted that the third threshold and the fourth threshold vary with the indoor windshield.
