When the air conditioner executes the self-cleaning instruction, the sterilization and disinfection of the air conditioner pipeline or the heat exchanger fin can be realized in a heating mode. The method for controlling the temperature rise and sterilization of the air conditioner is used in the self-cleaning temperature rise process of the air conditioner.

With reference to fig. 1, an embodiment of the present disclosure provides a method for controlling temperature rise sterilization of an air conditioner, including:

in step S01, when the indoor heat exchanger is warmed up, the target discharge temperature of the compressor is determined based on the target frequency of the compressor.

In some optional embodiments, a remote controller and a control panel of the air conditioner are added with a cleaning option of "sterilization function" or "sterilization function" and the like, and the cleaning option can be used for triggering a temperature-raising process for operating the temperature-raising sterilization of the air conditioner in the embodiment. Therefore, after the user selects the cleaning option, the air conditioner generates a related cleaning instruction and responds to and executes a corresponding temperature rising program.

In still other alternative embodiments, the air conditioner may also generate the related cleaning instruction by detecting a trigger, a timing trigger, or the like, for example, the air conditioner is additionally provided with a microorganism detection device, which may be used to detect the content of one or more specific types of microorganisms, and when the detected content of the microorganisms is higher than a set content threshold, it indicates that the air conditioner has a large number of microorganisms, and the air conditioner generates the related cleaning instruction; still alternatively, the air conditioner has a timing module, which is configured to count the cumulative operating time of the air conditioner, such as the cumulative operating time of the cooling mode or the dehumidifying mode, wherein as the cumulative operating time of the cooling mode or the dehumidifying mode of the air conditioner increases, the more condensed water is condensed inside the air conditioner and the more the number of microorganisms in the humid environment increases, so that the air conditioner may be configured to generate the related cleaning instruction when the cumulative operating time of the air conditioner exceeds the set time threshold.

In still other alternative embodiments, the air conditioner may also be triggered in linkage with the original cleaning function of the air conditioner, for example, after the original cleaning function is selected by a user, a cleaning instruction is generated and the cleaning method flow defined by the original cleaning function is executed before the cleaning flow defined by the original cleaning function is executed, or a cleaning instruction is generated and the cleaning method flow defined by the original cleaning function is executed after the cleaning flow defined by the original cleaning function is executed; that is, after the user selects an original cleaning function, the air conditioner executes two different cleaning processes in sequence, and the cleanliness of the interior of the air conditioner is effectively guaranteed through a double cleaning mode.

For example, the original cleaning function of the air conditioner is a spraying cleaning function, the spraying cleaning function is to spray water onto a heat exchanger of the air conditioner to clean the heat exchanger in a flowing water flushing manner, and an optional implementation manner is that the heating sterilization method flow of the present application is operated before the spraying cleaning function is executed, that is, after the spraying cleaning function is selected by a user, the heating sterilization method flow of the present application is controlled to kill microbes such as bacteria and the like, and then the spraying cleaning function is executed, so that the flowing water can not only flush dirt such as dust, oil stains and the like, but also flush the killed microbes on the heat exchanger.

Here, the target frequency of the compressor has a correlation with its rated frequency and can be obtained from the rated frequency. Alternatively, the air conditioner is pre-stored with the corresponding relation between the target frequency of the compressor and the target exhaust temperature, and the target exhaust temperature value corresponding to the target frequency can be determined according to the target frequency.

In step S02, the opening degree of the throttle device is set according to the target exhaust gas temperature.

By adopting the method for controlling the temperature rise and sterilization of the air conditioner, the temperature rise process is executed during the self-cleaning of the air conditioner, the target exhaust temperature of the compressor is determined according to the target frequency of the compressor, and the opening degree of the throttling device is further set according to the target exhaust temperature, so that the opening degree of the throttling device can be set, the air conditioner can run under the condition of the opening degree of the throttling device corresponding to the target exhaust temperature, and the speed of reaching the target exhaust temperature is accelerated. Therefore, in the temperature rising process, the speed of reaching the target exhaust temperature of the compressor is increased, the temperature rising speed of the air conditioner is increased, and the air conditioner can be sterilized and cleaned efficiently.

Alternatively, when the opening degree of the throttle device is set according to the target exhaust gas temperature, the opening degree of the throttle device is larger as the target exhaust gas temperature of the compressor is higher.

Here, the throttle device is provided as an electronic expansion valve. In the temperature rise process, the refrigerant flows into the outdoor heat exchanger from the indoor heat exchanger, and in order to ensure the defrosting effect in the temperature rise process, the refrigerant flowing into the outdoor heat exchanger can absorb more heat from the external environment, so that the opening degree of the throttling device is adjusted to enable the throttling device to adapt to the heat exchange requirement under the current outdoor environment temperature condition, and the temperature rise sterilization effect of the indoor heat exchanger is ensured. The opening degree of the throttling device is set according to the target exhaust temperature of the compressor, so that the throttling device can meet the heat exchange requirement under the target operation condition of the compressor.

Alternatively, setting the opening degree of the throttle device according to a target discharge temperature of the compressor includes: acquiring the opening degree of a throttling device corresponding to the target opening degree of the compressor according to a preset corresponding relation; the throttle opening is executed.

Illustratively, an alternative compressor target discharge temperature and throttle opening during warm-up is shown in table 1.

TABLE 1

Compressor target discharge temperature T (. degree. C.)	Opening degree F of throttle device
		Tao＜T1	F01
T1≤Tao＜T2	F02
		T2≤Tao＜T3	F03
T3≤Tao＜T4	F04
		T4≤Tao＜T5	F05
T5≤Tao＜T6	F06
		T6≤Tao	F07

In this embodiment, 7 temperature ranges are preset for the target compressor discharge temperature, and the corresponding throttle opening F values decrease in sequence. Table 1 shows values of the opening F of the throttling device corresponding to different temperature intervals where the target exhaust temperature of the compressor is located, in this embodiment, the value of the opening F of the throttling device during the temperature rising process may be determined by a table lookup manner according to the value of the target exhaust temperature.

Alternatively, the target discharge temperature of the compressor is determined by:

T₀＝a×F₀+b (1)

wherein, T₀Is the compressor target discharge temperature, F₀For the compressor target frequency, a is a weighted value and b is a corrected value.

Here, the value of the compressor target discharge temperature is related to the compressor target frequency. and a is a weighted value larger than 0, and b is a corrected value, and the more accurate target exhaust temperature is obtained by correcting the numerical value obtained based on the target frequency. It should be noted that in the calculation of equation (1), T is performed₀、F₀The algebraic expression of the numerical value is evaluated without performing unit conversion.

Optionally, the value of the weighted value a has a corresponding relationship with the outdoor ambient temperature. Different values are set for the weighting value a according to different outdoor ambient temperatures. Optionally, the value of the weighted value a is also related to the operation mode of the air conditioner before receiving the cleaning instruction. Optionally, the value of the correction value b has a corresponding relationship with the outdoor ambient temperature.

Optionally, the outdoor ambient temperature is acquired in real time or at predetermined time intervals. For example, during the warming process of the heat exchanger, the outdoor ambient temperature is acquired in real time to set the target discharge temperature of the compressor. It is also possible that, in the warming-up process, the outdoor ambient temperature is acquired at predetermined time intervals to set the target discharge temperature of the compressor. Here, the predetermined time interval may be 1min, 2min, 4min or 5 min.

Alternatively, the target frequency of the compressor in equation (1) is determined by:

F₀＝k×F₁(2)

wherein, F₀For a compressor target frequency, F₁K is a weighting coefficient for the rated heating frequency of the compressor.

Here, the weighting coefficient k is determined according to the outdoor ambient temperature. Therefore, in the temperature rising process, when the target frequency of the compressor is obtained, the rated heating frequency of the compressor is corrected through the outdoor environment temperature, the current environment temperature can be adapted to, the influence of the outdoor environment temperature on the change of the operation parameters of other parts of the air conditioner is avoided, and the stable operation of the air conditioner is kept.

Optionally, in the case that the outdoor environment temperature is less than or equal to 0 ℃, the weighting coefficient k is determined according to the ratio of the maximum qualified frequency of the noise in the heating mode to the rated frequency; and under the condition that the outdoor environment temperature is greater than 0 ℃, the weighting coefficient k is determined according to the frequency limiting coefficient corresponding to the outdoor environment temperature.

The rated heating frequency is a rated value having an association relationship with the air conditioner energy efficiency. Further, the maximum qualified frequency of the heating test noise under each temperature working condition is obtained according to a large number of tests of the noise environment of the air conditioner in the research and development stage. Under different ambient temperatures, the maximum frequency values of the qualified noise in the heating mode are different.

Under the condition that the outdoor environment temperature is less than or equal to 0 ℃, the value of the weighting coefficient k is stored after hexadecimal conversion is carried out on the value of the ratio of the maximum qualified noise frequency to the rated frequency in the heating mode.

Under the condition that the outdoor environment temperature is higher than 0 ℃, the value of the weighting coefficient k is determined by obtaining the frequency limiting coefficient of the outdoor environment temperature, and the weighting coefficient k is subjected to hexadecimal conversion and then stored.

Illustratively, an alternative correspondence between the outdoor ambient temperature and the weighting factor k is shown in table 2.

TABLE 2

Outdoor ambient temperature Tao	Weighting factor k
		Tao≤-20℃	139
-20℃＜Tao≤-10℃	138
		-10℃＜Tao≤-5℃	136
-5℃＜Tao≤0℃	132
		0℃＜Tao≤5℃	128
5℃＜Tao≤10℃	115
		10℃＜Tao≤16℃	99
16℃＜Tao≤22℃	80
		22℃＜Tao	59

And presetting 9 temperature intervals for the outdoor environment temperature, and sequentially reducing the numerical values of the corresponding weighting coefficients k. Table 1 shows values of the weighting coefficient k corresponding to different temperature intervals where the outdoor ambient temperature is located, where the value of the weighting coefficient k is an example value. It can be seen that the higher the outdoor ambient temperature is, the smaller the value of the weighting coefficient k is.

Optionally, the temperature raising program is exited after the temperature of the indoor coil of the air conditioner meets the temperature raising end condition.

Wherein, the heating-up ending condition comprises that the numerical value of the temperature of the coil pipe of the indoor heat exchanger is continuously greater than the set temperature in the preset time. Here, the set temperature was set to 56 ℃, and the preset time period was set to 35 minutes.

Alternatively, in the case where the rate of change of the actual exhaust temperature is less than 1 for a set period of time, it is determined that the current system operation is stable. Alternatively, whether the current system is stable or not can be determined according to the opening change rate of the electronic expansion valve. And in a detection period, if the opening change of the electronic expansion valve is smaller than a set threshold value, the current system is considered to be stable. Here, the detection period may be 5s or 10s, and the set threshold value related to the valve opening degree may have a value ranging from 2 to 4 steps, and may be 2 steps, 3 steps, or 4 steps.

Here, the sterilization temperature was set to 56 ℃, and the set time period was set to 35 minutes.
