With the development of intelligent technology and the increase of consumer demand, air conditioners are endowed with functions other than cooling and heating, such as self-cleaning and sterilization functions. In the process of self-cleaning and sterilization, the temperature of the inner coil of the indoor unit is required to reach more than 56 ℃. When the temperature of the inner coil is used as an object to be regulated, the problem of temperature fluctuation may exist, and a part of bacteria cannot be killed.
Referring to fig. 1, an embodiment of the present disclosure provides a method for cleaning control of an air conditioner, including:
and S210, the air conditioner responds to the cleaning instruction to obtain the target frequency of the compressor.
And S220, the air conditioner adjusts the target exhaust temperature of the compressor according to the target frequency, so that the target exhaust temperature is higher than a first set temperature.
By adopting the method for cleaning and controlling the air conditioner, the air conditioner receives and responds to the cleaning instruction under the condition that high-temperature sterilization is required. And obtaining the target frequency of the compressor, and determining whether the target frequency of the compressor is suitable for high-temperature sterilization, so that the condition that the fault of the compressor affects the service life of the air conditioner is avoided. And adjusting the target exhaust temperature of the compressor according to the target frequency of the compressor to enable the target exhaust temperature to be larger than the first set temperature. Because the exhaust temperature of the compressor is the highest temperature point in the air conditioner and has a small difference with the temperature of the inner coil, when the target exhaust temperature is higher than the first set temperature, the temperature of the inner coil can be ensured to meet the requirement of high temperature all the time, so that the high-temperature sterilization effect of the air conditioner is improved.
Optionally, the first set temperature is in a range of [56, 56.4] ° c. Preferably, the first set temperature is 56.1 ℃, 56.2 ℃ or 56.3 ℃. In this way, the target exhaust temperature of the compressor is controlled to be higher than the first set temperature, and the difference between the temperature of the inner coil and the target exhaust temperature is small, so that the temperature of the inner coil is still kept above the temperature required for sterilization under the condition that the indoor and outdoor environmental parameters are greatly changed.
Referring to fig. 2, another method for cleaning control of an air conditioner according to an embodiment of the present disclosure includes:
and S210, the air conditioner responds to the cleaning instruction to obtain the target frequency of the compressor.
S230, if the target frequency is greater than the first set frequency, the air conditioner keeps the target frequency unchanged, and step S250 is executed.
And S240, under the condition that the target frequency is less than or equal to the first set frequency, the air conditioner adjusts the target frequency.
And S250, determining the target exhaust temperature of the compressor by the air conditioner according to the target frequency.
And S260, the air conditioner adjusts the target exhaust temperature according to the relation between the target exhaust temperature and the first set temperature.
By adopting the method for cleaning and controlling the air conditioner, which is provided by the embodiment of the disclosure, the exhaust temperature of the compressor required in high-temperature sterilization is high, and the compressor runs under the condition of low target frequency, so that faults such as desynchronization of the running of the compressor are easily caused, and the service life and reliability of the air conditioner are influenced. The target frequency of the compressor is adjusted to be suitable for the required exhaust temperature, so that the operation stability of the compressor is improved and the requirement of the exhaust temperature is met.
Optionally, the first set frequency is in a range of [40, 44] Hz. Preferably, the first set frequency is 41Hz, 42Hz or 43 Hz. In this way, since the target discharge temperature of the compressor is controlled to be higher than the first set temperature, when the value of the target frequency is higher than the value of the first set frequency, the target frequency of the compressor is adapted to the required discharge temperature. Since the compressor is operated at a medium and high frequency at a high discharge temperature, reliability and stability of operation can be improved.
Referring to fig. 3, another method for cleaning control of an air conditioner according to an embodiment of the present disclosure includes:
and S210, the air conditioner responds to the cleaning instruction to obtain the target frequency of the compressor.
S230, if the target frequency is greater than the first set frequency, the air conditioner keeps the target frequency unchanged, and step S250 is executed.
And S241, increasing the target frequency by the compensation frequency by the air conditioner under the condition that the target frequency is less than or equal to the first set frequency.
S242, if the target frequency is greater than the first set frequency, the air conditioner keeps the target frequency unchanged, and step S250 is executed.
And S243, in case that the target frequency is less than or equal to the first set frequency, the air conditioner determines the second set frequency as the target frequency.
And S250, determining the target exhaust temperature of the compressor by the air conditioner according to the target frequency.
And S260, the air conditioner adjusts the target exhaust temperature according to the relation between the target exhaust temperature and the first set temperature.
The second set frequency is greater than the first set frequency.
By adopting the method for cleaning and controlling the air conditioner, provided by the embodiment of the disclosure, when the target frequency cannot enable the compressor to stably run in the high-temperature sterilization process, the target frequency is improved in a mode of self-increasing and compensating the frequency. Because the compressor is operated at the low target frequency under the condition that the indoor ambient temperature and the outdoor ambient temperature are high, when the target frequency is increased and the requirement of stable operation of the compressor cannot be met, the target frequency is adjusted to be the second set frequency higher than the first set frequency. Because the adjusted target frequency is higher than the first set frequency, the problem that the compressor cannot stably operate at the current indoor and outdoor ambient temperatures by increasing the frequency allowance is avoided, and the operation stability of the compressor at the high exhaust temperature is improved.
Optionally, the compensation frequency has a value range of [8, 12] Hz. Preferably, the compensation frequency takes the value of 9Hz, 10Hz or 11 Hz. The second set frequency has a value in the range of [45, 49] Hz. Preferably, the second set frequency is 46Hz, 47Hz or 48 Hz. Therefore, when the value of the compensation frequency is in the range, the change of the target frequency of the compressor is small, and the fluctuation of the operation parameters is avoided to be large, so that the stability of the operation of the compressor is improved. When the value of the second set frequency is in the range, the allowance of the difference between the second set frequency and the first set frequency enables the compressor to stably operate at the current indoor and outdoor ambient temperature, and the operation stability of the compressor at the high exhaust temperature is improved.
Referring to fig. 4, another method for cleaning control of an air conditioner according to an embodiment of the present disclosure includes:
and S210, the air conditioner responds to the cleaning instruction to obtain the target frequency of the compressor.
S230, if the target frequency is greater than the first set frequency, the air conditioner keeps the target frequency unchanged, and step S251 is executed.
And S240, under the condition that the target frequency is less than or equal to the first set frequency, the air conditioner adjusts the target frequency.
And S251, detecting the outdoor environment temperature by the air conditioner.
And S252, the air conditioner determines the target exhaust temperature of the compressor according to the target frequency and the outdoor environment temperature.
And S261, when the target exhaust temperature is higher than the first set temperature, the air conditioner keeps the target exhaust temperature unchanged, and the control is finished.
And S262, under the condition that the target exhaust temperature is less than or equal to the first set temperature, the air conditioner determines the second set temperature as the target exhaust temperature, and the control is finished.
Wherein the second set temperature is greater than the first set temperature.
With the method for air conditioner cleaning control provided by the embodiment of the present disclosure, since the target frequency of the compressor may affect the target discharge temperature, the target discharge temperature is re-determined after the target frequency is determined. By detecting the outdoor ambient temperature, a target discharge temperature is determined from the outdoor ambient temperature to perform temperature compensation for the target discharge temperature determined by the target frequency. And under the condition that the determined target exhaust temperature is higher than the first set temperature, the target exhaust temperature can enable the temperature of the inner coil to realize high-temperature sterilization and keep the target exhaust temperature unchanged. And under the condition that the determined target exhaust temperature is less than or equal to the first set temperature, adjusting the target exhaust temperature to a second set temperature with allowance, and avoiding that the target exhaust temperature can not enable the temperature of the inner coil to reach the sterilization temperature. The target exhaust temperature is determined according to the target frequency and the outdoor environment temperature, and is adjusted under the condition that the target exhaust temperature is low, so that the temperature of the inner coil pipe always meets the high-temperature requirement, and the high-temperature sterilization effect of the air conditioner is improved.
Alternatively, the higher the target frequency, the higher the target discharge temperature, with a constant outdoor ambient temperature. In the case where the target frequency is constant, the higher the outdoor ambient temperature is, the higher the target discharge temperature is. The air conditioner in step S252 determines a target discharge temperature of the compressor according to the target frequency and the outdoor ambient temperature, including: t is a unit of d ＝α×f t + β + γ. Wherein, T d Alpha is a frequency conversion coefficient, f t The target frequency is beta, the temperature correction amount is beta, and the outdoor environment temperature compensation amount is gamma. The value range of the frequency conversion coefficient alpha is [0.01, 2]]. Alpha takes different values according to the type of the air conditioner and the compressor, the application scene, the environmental parameters and the like. For this disclosureIn the method for controlling cleaning of an air conditioner according to the embodiment, the value range of α is [0.5, 0.7 ]]. The value range of the temperature correction beta is [ -50, 200 [ -50 [ ]]. Beta takes different values according to the type of the air conditioner and the compressor, the application scene, the environmental parameters and the like. For the method for cleaning and controlling the air conditioner provided by the embodiment of the disclosure, the value range of beta is [20, 80 ]]. The values of the outdoor environment temperature compensation amount γ are shown in table 1. Therefore, the target exhaust temperature can be accurately calculated according to the target frequency and the outdoor environment temperature, and is adaptive to the target frequency and the outdoor environment temperature, so that the running stability of the compressor is improved. Because the accuracy of the target exhaust temperature is high, the temperature of the inner coil pipe is always kept above the temperature required by sterilization, so that the high-temperature sterilization effect of the air conditioner is improved.
The correspondence between the outdoor environment temperature compensation amount and the outdoor environment temperature is shown in table 1:
TABLE 1
| T ao | T ao ≤0℃ | 0℃<T ao ≤10℃ | 10℃<T ao ≤20℃ | 20℃<T ao |
| γ | -13 | -3 | 6 | 8 |
Wherein, T ao Is the outdoor ambient temperature and gamma is the outdoor ambient temperature compensation.
Optionally, the second set temperature is in a range of [58, 58.4] ° c. Preferably, the second set temperature is 58.1 ℃, 58.2 ℃ or 58.3 ℃. Thus, when the value of the second set temperature is in the range, the allowance of the difference between the second set temperature and the first set temperature enables the temperature of the inner coil to reach the sterilization temperature, so that the high-temperature sterilization effect of the air conditioner is improved.
Referring to fig. 5, another method for cleaning control of an air conditioner according to an embodiment of the present disclosure includes:
and S210, the air conditioner responds to the cleaning instruction to obtain the target frequency of the compressor.
S220, the air conditioner adjusts the target exhaust temperature of the compressor according to the target frequency, and the target exhaust temperature is larger than a first set temperature.
And S270, controlling the compressor to run at the target frequency by the air conditioner.
And S280, the air conditioner adjusts the rotating speed of the outdoor fan.
And S290, detecting the current exhaust temperature of the compressor by the air conditioner.
And S300, when the current exhaust temperature is lower than the target exhaust temperature, the air conditioner adjusts the opening degree of the electronic expansion valve and returns to the step S290.
By adopting the method for cleaning and controlling the air conditioner, the running frequency of the compressor and the rotating speed of the outdoor fan are adjusted before high-temperature sterilization is carried out. After the frequency and the rotating speed are adjusted, the current exhaust temperature of the compressor is detected. Under the condition that the current exhaust is lower than the target exhaust temperature, the temperature of the inner coil does not reach the sterilization temperature, so that the sterilization effect is poor. The current exhaust temperature of the compressor is adjusted to the target exhaust temperature by adjusting the opening of the electronic expansion valve, so that the temperature of the inner coil pipe meets the high-temperature requirement to improve the high-temperature sterilization effect of the air conditioner.
Optionally, the adjusting the rotation speed of the outdoor fan by the air conditioner in step S280 includes: and the air conditioner determines the target rotating speed of the outdoor fan corresponding to the outdoor environment temperature and the target frequency according to the outdoor environment temperature and the target frequency. The air conditioner adjusts the rotating speed of the outdoor fan to a target rotating speed. Thus, under the condition that the outdoor environment temperature is low, the current exhaust temperature of the compressor reaches the target exhaust temperature by increasing the rotating speed of the outdoor fan. And under the condition of high target frequency, increasing the rotating speed of the outdoor fan to enable the current exhaust temperature of the compressor to reach the target exhaust temperature. The target rotating speed of the corresponding outdoor fan is determined under different outdoor environment temperatures and target frequencies, so that the current exhaust temperature of the compressor reaches the target exhaust temperature to improve the high-temperature sterilization effect of the air conditioner.
The corresponding relationship between the target rotating speed of the outdoor fan and the outdoor environment temperature and the target frequency is shown in table 2:
TABLE 2
Wherein, T ao Is the outdoor ambient temperature, f t Is the target frequency of the compressor, n t Is the target rotating speed of the outdoor fan.
Alternatively, the air conditioner in step S300 adjusts the opening of the electronic expansion valve, and determines the opening correction amount of the electronic expansion valve through pid control according to the current exhaust temperature. The air conditioner determines the sum of the current opening degree of the electronic expansion valve and the opening degree correction quantity as a target opening degree. The air conditioner adjusts the opening degree of the electronic expansion valve to a target opening degree. Thus, the opening correction amount of the electronic expansion valve is determined by the proportional integral derivative control based on the current exhaust temperature, and the opening of the electronic expansion valve is gradually adjusted. The opening correction amount is based on the current exhaust temperature, and after opening adjustment is performed each time, the current exhaust temperature can be closer to reach the target exhaust temperature. The accuracy of the current exhaust temperature adjustment is improved through proportional-integral-derivative control, so that the high-temperature sterilization effect of the air conditioner is improved.
Referring to fig. 6, another method for cleaning control of an air conditioner according to an embodiment of the present disclosure includes:
and S210, the air conditioner responds to the cleaning instruction to obtain the target frequency of the compressor.
S220, the air conditioner adjusts the target exhaust temperature of the compressor according to the target frequency, and the target exhaust temperature is larger than a first set temperature.
And S270, the air conditioner controls the compressor to operate at the target frequency.
And S280, adjusting the rotating speed of the outdoor fan by the air conditioner.
And S290, detecting the current exhaust temperature of the compressor by the air conditioner.
And S300, when the current exhaust temperature is lower than the target exhaust temperature, the air conditioner adjusts the opening degree of the electronic expansion valve and returns to the step S290.
And S310, controlling the indoor fan to stop running by the air conditioner under the condition that the current exhaust temperature is greater than or equal to the target exhaust temperature.
And S320, controlling the indoor fan to operate at a set rotating speed by the air conditioner under the condition that the indoor fan is controlled to stop operating for a first set time.
