In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.
As shown in fig. 1, an embodiment of the present disclosure provides an air conditioner control method, including:
after the air conditioner is started, determining the running frequency of the compressor of the air conditioner according to the temperature of the air outlet duct, the ambient temperature and the preset compressor starting frequency corresponding to the set temperature.
Herein, the ambient temperature refers to a temperature of an environment in which the air conditioner operates. For example, when the air conditioner is indoors, the ambient temperature refers to an indoor temperature, and when the air conditioner is outdoors, the ambient temperature refers to an outdoor ambient temperature.
By adopting the embodiment, after the air conditioner is started, the air conditioner is not directly operated at the preset compressor starting frequency, the compressor operating frequency is not directly determined according to the relationship between the set temperature and the environment temperature, the temperature of the air outlet duct, the environment temperature and the preset compressor starting frequency are considered in a combined manner, and then the compressor operating frequency of the air conditioner is determined, so that the phenomenon that the temperature of parts in the air conditioner is changed violently due to overlarge preset compressor starting frequency when the air conditioner is directly operated at the preset compressor starting frequency after the air conditioner is started is avoided, and the heat expansion and cold contraction sound is generated; or after the air conditioner is started, under the condition that the operation frequency of the compressor is directly determined according to the relationship between the set temperature and the environment temperature, the operation frequency of the compressor is overlarge to cause the temperature of parts in the air conditioner to be changed violently, so that the heat expansion and cold contraction sound is generated.
Alternatively, the outlet air duct temperature may be measured by a coil temperature detection device of the indoor heat exchanger.
Alternatively, the ambient temperature may be measured by an ambient temperature sensing device of the air conditioner.
Optionally, the determining the operating frequency of the compressor of the air conditioner according to the temperature of the air outlet duct, the ambient temperature, and the preset compressor starting frequency corresponding to the set temperature may be:
determining the operating frequency of the compressor according to the relationship among the temperature of the air outlet duct, the ambient temperature and the preset starting frequency of the compressor, for example:

By adopting the embodiment, the numerical value of the third temperature difference is detected in real time, and when the third temperature difference is reduced, the running frequency of the compressor is increased so as to approach to the preset starting frequency of the compressor, thereby realizing slow heating or refrigeration, avoiding the temperature of parts in the air conditioner from changing violently, and ensuring the heating or refrigeration efficiency while generating expansion with heat and contraction with cold.
Optionally, when the third temperature difference does not exceed the third temperature difference threshold, the compressor operating frequency is consistent with the preset compressor starting frequency.

Therefore, by adopting the embodiment, the starting frequency of the compressor of the air conditioner is determined according to the second temperature difference and the preset starting frequency of the compressor, so that the occurrence of thermal expansion and cold contraction noise is avoided.
Optionally, determining the compressor starting frequency of the air conditioner according to the second temperature difference and a preset compressor starting frequency includes:
and when the second temperature difference exceeds a second temperature difference threshold value, determining that the starting frequency of the compressor is lower than the preset starting frequency of the compressor.

Optionally, when the first temperature difference does not exceed the first temperature difference threshold, the compressor operating frequency is consistent with a preset compressor starting frequency.
With the present embodiment, when the first temperature difference does not exceed the first temperature difference threshold, it indicates that the condition of easy formation of thermal expansion and cold contraction is eliminated, the operating frequency of the compressor is consistent with the preset compressor starting frequency, and then the operating frequency of the compressor is controlled according to the conventional air conditioner control method, for example, the operating frequency of the compressor is controlled according to the temperature difference between the set temperature and the ambient temperature, so as to implement cooling or heating.
An application scenario of the air conditioner control method according to the embodiment of the present disclosure is exemplarily described below.
For example, when the air conditioner is to be started up for heating, the indoor temperature is detected to be 10 ℃, the set temperature is 28 ℃, the first temperature difference between the indoor temperature and the set temperature is 18 ℃, and the preset startup frequency adjustment value of the compressor corresponding to the temperature difference value is assumed to be-15 HZ, namely 15HZ is reduced relative to the preset startup frequency of the compressor.
The above process is equivalent to determining the starting frequency of the compressor of the air conditioner according to the set temperature, the ambient temperature and the preset starting frequency of the compressor when the air conditioner is started; and when the second temperature difference between the set temperature and the environment temperature exceeds a second temperature difference threshold value, determining that the starting frequency of the compressor of the air conditioner is lower than the preset starting frequency of the compressor.
When the compressor runs for a period of time at a frequency 15HZ lower than the preset starting frequency of the compressor, introducing hot air into the air outlet duct, and inputting the hot air into a room; at this moment, the indoor temperature and the temperature of the air outlet duct can be changed. Assuming that the indoor temperature becomes 15 deg.c, the corresponding second temperature difference is 13 deg.c, and assuming that the corresponding compressor operation frequency adjustment value is-10 HZ, i.e., 10HZ is reduced with respect to the preset compressor starting frequency.
When the compressor runs for a period of time at a frequency lower than the preset compressor starting frequency of 10HZ, the indoor temperature is changed to 25 ℃, the corresponding second temperature difference is 3 ℃, the adjustment value of the running frequency of the compressor is 0 assuming that the second temperature difference value does not exceed the second temperature difference threshold value, and the air conditioner controls the running of the compressor at the preset compressor starting frequency.
The above process is equivalent to determining the running frequency of the compressor of the air conditioner according to the set temperature, the ambient temperature and the preset starting frequency of the compressor after the air conditioner is started; when the first temperature difference between the set temperature and the ambient temperature exceeds a first temperature difference threshold value, determining that the running frequency of the compressor of the air conditioner is lower than the starting frequency of the preset compressor; further, when the first temperature difference is reduced, the running frequency of the compressor of the air conditioner is increased to approach the preset starting frequency of the compressor until the running frequency is consistent with the preset starting frequency of the compressor.
Alternatively, the adjustment time interval of the compressor operation frequency may be 30 seconds. After the air conditioner is started, the running frequency of the compressor is adjusted every 30 seconds to slowly increase the running frequency of the compressor to the preset starting frequency, so that the air conditioner is beneficial to avoiding the severe temperature change of parts in the air conditioner and the generation of expansion with heat and contraction with cold at the initial starting running stage.
