specifically, the cooling operation duration refers to a time for which the air conditioner continues to cool once, for example, 2; for example, 3; i.e. a period of time that is not intermittent.

Furthermore, a period of time is required from the power-on of the air conditioner to the start of refrigeration, and the timing is started after the refrigeration is started.

Specifically, the preset heat exchange efficiency may be selected from 90%, 85%, 80%, and the like, and those skilled in the art may select the heat exchange efficiency according to actual situations. That is, under the condition that the heat exchange condition of the outdoor heat exchanger is good, the higher refrigeration requirement of the air conditioner can be met, and the subsequent degerming step is facilitated.

It should be noted that the factors affecting the heat exchange efficiency of the outdoor heat exchanger include: whether the pipeline of the outdoor heat exchanger is dirty or not, whether the pipeline of the outdoor heat exchanger has cracks or not and the like.

Specifically, determining whether the air conditioner meets the refrigeration requirement at least according to the tube temperature of the outdoor heat exchanger includes determining whether the air conditioner meets the refrigeration requirement only according to the tube temperature of the outdoor heat exchanger, and also includes determining whether the air conditioner meets the refrigeration requirement according to the tube temperature of the outdoor heat exchanger and other factors;

and step S103, determining whether to enter a high-temperature sterilization mode according to the indoor environment temperature under the condition that the air conditioner meets the refrigeration requirement.

In step S103, when the cooling demand is satisfied, it is further necessary to determine whether or not to start the high-temperature sterilization process based on information such as the magnitude of the indoor ambient temperature.

In the scheme, the refrigerating operation time of the air conditioner is obtained, whether the air conditioner meets the refrigerating requirement is determined at least according to the pipe temperature of the outdoor heat exchanger under the condition that the refrigerating operation time is longer than or equal to the first preset time, and whether the air conditioner enters the high-temperature sterilization mode is determined according to the indoor environment temperature under the condition that the air conditioner meets the refrigerating requirement. By adopting the scheme, the comfort of refrigeration is ensured while high-temperature sterilization is realized.

In an alternative embodiment, step S102: under the condition that the refrigerating operation time length is greater than or equal to a first preset time length, whether the air conditioner meets the refrigerating requirement is determined at least according to the pipe temperature of the outdoor heat exchanger, and the method has the following two implementation modes: the first implementation mode comprises the following steps: determining whether the air conditioner meets the refrigeration requirement according to the outdoor environment temperature and the pipe temperature of the outdoor heat exchanger; the outdoor environment temperature and the tube temperature of the outdoor heat exchanger are comprehensively considered to determine whether the refrigeration requirement is met; the second implementation mode comprises the following steps: and determining whether the air conditioner meets the refrigeration requirement according to the pipe temperature of the outdoor heat exchanger. I.e., the determination of whether the refrigeration demand is satisfied can be made based solely on the outdoor heat exchanger tube temperature determination.

In a specific embodiment, for the first implementation: determining whether the air conditioner meets the refrigeration requirement according to the outdoor environment temperature and the pipe temperature of the outdoor heat exchanger, comprising the following steps: step S1021: acquiring a first temperature difference value, wherein the first temperature difference value refers to the difference value between the outdoor environment temperature and the tube temperature of the outdoor heat exchanger; step S1022: and determining that the air conditioner meets the refrigeration requirement under the condition that the first temperature difference is greater than or equal to a first difference threshold and less than or equal to a second difference threshold. Specifically, the first difference threshold and the second difference threshold may be obtained according to actual test tests, and a person skilled in the art may adjust the first difference threshold and the second difference threshold according to actual requirements, so as to ensure accuracy of the first difference threshold and the second difference threshold, and further ensure accuracy of determining whether the air conditioner meets the refrigeration requirement.

In a specific embodiment, for the second implementation: whether the air conditioner meets the refrigeration requirement is determined only according to the tube temperature of the outdoor heat exchanger, and the method can be realized as follows: and determining that the air conditioner meets the refrigeration requirement under the condition that the tube temperature of the outdoor heat exchanger is greater than or equal to a first temperature threshold and less than or equal to a second temperature threshold. That is, only considering the temperature of the outdoor heat exchanger tube, the temperature of the outdoor heat exchanger tube may be within a range from the first temperature threshold to the second temperature threshold, specifically, the first temperature threshold and the second temperature threshold may be obtained according to an actual test, and a person skilled in the art may adjust the temperature according to an actual requirement to ensure the accuracy of the first temperature threshold and the second temperature threshold, and further ensure the accuracy of determining whether the air conditioner meets the refrigeration requirement.

In an alternative embodiment, step S103: under the condition that the air conditioner meets the refrigeration requirement, whether to enter a high-temperature sterilization mode is determined according to the indoor environment temperature, and the method comprises the following steps:

step S1031: determining whether the indoor environment temperature is less than or equal to a third temperature threshold value in real time;

step S1032: in the case where the indoor ambient temperature is less than or equal to the third temperature threshold, determining whether at least one of: whether the absolute value of a second difference value is smaller than a third difference value threshold value or not and whether the temperature drop rate is larger than or equal to a preset rate or not, wherein the second difference value refers to the difference value between an indoor preset temperature and the indoor environment temperature, and the temperature drop rate refers to the ratio of the difference value between the indoor environment temperature at the current moment and the indoor environment temperature at the power-on moment to the refrigerating operation length at the current moment;

step S1033: and if the condition is met, determining to enter the high-temperature sterilization mode.

Specifically, the third temperature threshold, the third difference threshold and the preset rate can be obtained according to actual test tests, and a person skilled in the art can adjust the third temperature threshold, the third difference threshold and the preset rate according to actual requirements to ensure the accuracy of the third temperature threshold, the third difference threshold and the preset rate, so as to realize accurate control on whether the air conditioner enters a high-temperature sterilization mode, and further ensure the accuracy of determining whether the air conditioner meets the refrigeration requirement.

In the above scheme, after the refrigeration requirement is met, whether to enter the high-temperature sterilization mode is further determined according to the indoor environment temperature, the difference between the indoor preset temperature and the indoor environment temperature, and the temperature drop rate. So as to realize the accurate control of the threshold for determining to enter the high-temperature sterilization mode.

In some embodiments, at step S1032: in a case where the indoor ambient temperature is less than or equal to the third temperature threshold, determining whether at least one of the following is satisfied: after whether the absolute value of the second difference is smaller than the third difference threshold and whether the temperature drop rate is greater than or equal to the preset rate, the method further includes: and under the condition of not meeting the requirement, determining whether to enter the high-temperature sterilization mode or not according to the pipe temperature of the outdoor heat exchanger at least at the current moment. That is, if the above condition is not satisfied, whether to enter the high temperature sterilization mode may be further determined according to the outdoor heat exchanger tube temperature at the present time. To achieve an accurate determination of whether to enter the above-described pasteurization mode.

In a more specific embodiment, in the event that the temperature of the outdoor heat exchanger is not satisfied, determining whether to enter the high-temperature sterilization mode at least according to the temperature of the outdoor heat exchanger tube at the current moment includes two implementation manners: the first mode is as follows: under the condition of not being satisfied, determining whether to enter the high-temperature sterilization mode or not according to the outdoor environment temperature at the current moment and the outdoor heat exchanger tube temperature at the current moment; the second mode is as follows: and under the condition of not meeting the requirement, determining whether to enter the high-temperature sterilization mode according to the pipe temperature of the outdoor heat exchanger. That is, if the "absolute value of the second difference is smaller than the third difference threshold and the temperature drop rate is greater than or equal to at least one of the preset rates" is not satisfied, whether to enter the high-temperature sterilization mode is determined according to the outdoor environment temperature at the present time and the outdoor heat exchanger tube temperature at the present time, or whether to enter the high-temperature sterilization mode is determined only according to the outdoor heat exchanger tube temperature. The absolute value of the second difference is smaller than the third difference threshold or the temperature drop rate is greater than or equal to the preset rate, which indicates that the room temperature drops faster, the heat loss of the room temperature is less and the heat preservation capability is better.

Specifically, the first method: under the condition of not meeting the requirements, determining whether to enter the high-temperature sterilization mode according to the outdoor environment temperature at the current moment and the pipe temperature of the outdoor heat exchanger at the current moment, wherein the method comprises the following steps: acquiring a second temperature difference value, wherein the second temperature difference value refers to the difference value between the outdoor environment temperature at the current moment and the tube temperature of the outdoor heat exchanger at the current moment; and determining to enter the high-temperature sterilization mode under the condition that the second temperature difference is smaller than a fourth difference threshold. That is, in the case that "the absolute value of the second difference is smaller than the third difference threshold and the temperature drop rate is greater than or equal to at least one of the preset rates" is not satisfied, it is determined whether to enter the pasteurization mode or not according to the difference between the outdoor environment temperature at the present time and the tube temperature of the outdoor heat exchanger at the present time. The fact that the second temperature difference is smaller than the fourth difference threshold value indicates that the rotating speed of the compressor is high, the heat exchange performance is good, at least one of the conditions that the absolute value of the second difference is smaller than the third difference threshold value and the temperature drop rate is larger than or equal to the preset rate does not meet the set requirement because the cold air sinks in the room, the detection is caused by the deviation, and the actual refrigerating effect of the room is good. Specifically, the fourth difference threshold may be obtained according to actual test tests, and those skilled in the art may adjust the fourth difference threshold according to actual requirements to ensure accuracy of the fourth difference threshold, so as to implement accurate control on whether to enter a high-temperature sterilization mode, and further ensure accuracy of determining whether the air conditioner meets refrigeration requirements.

Specifically, the second way: under the condition of not being satisfied, determining whether to enter the high-temperature sterilization mode according to the tube temperature of the outdoor heat exchanger only, wherein the method comprises the following steps: and determining to enter the high-temperature sterilization mode under the condition of the fourth temperature threshold of the outdoor heat exchanger pipe Wen Xiaoyu at the current moment. The fourth temperature threshold of the outdoor heat exchanger tube Wen Xiaoyu at the current moment indicates that the rotating speed of the compressor is high, the heat exchange performance is good, at least one of the conditions that the absolute value of the second difference is smaller than the third difference threshold and the temperature drop rate is larger than or equal to the preset rate does not meet the set requirement because the cold air sinks in the room, the set requirement is caused by the detection deviation, and the actual refrigeration effect of the room is good. Specifically, the fourth temperature threshold value can be obtained according to actual test tests, and technicians in the field can adjust according to actual requirements to ensure the accuracy of the fourth temperature threshold value, so as to realize accurate control on whether to enter a high-temperature sterilization mode, and further ensure the accuracy of determining whether the air conditioner meets the refrigeration requirement.

In some embodiments, the above method further comprises: after entering the high-temperature sterilization mode, determining whether preset conditions are met, wherein the preset conditions are as follows: the pipe temperature of the indoor heat exchanger is greater than or equal to a fifth temperature threshold, and the high-temperature sterilization time is greater than or equal to a second preset time; and controlling the air conditioner to exit the high-temperature sterilization mode under the condition that the preset condition is met. Namely, after entering the high-temperature sterilization mode, whether the high-temperature sterilization mode needs to be exited is judged according to the real-time detected pipe temperature of the indoor heat exchanger and the high-temperature sterilization duration. Namely, under the condition that the high-temperature sterilization mode needs to be exited, the high-temperature sterilization mode is exited in time, and the energy consumption is saved on the premise of ensuring the sterilization effect.

In some embodiments, when it is determined to perform high-temperature sterilization, the four-way valve needs to be controlled to change the direction, so that the air conditioner is switched from the refrigeration operation mode to the high-temperature sterilization mode, the rotating speed of the indoor fan is reduced, and the air deflector can be closed or the opening angle of the air deflector can be reduced.

In some embodiments, after controlling the air conditioner to exit the high temperature sterilization mode, the method further includes: and controlling the four-way valve in the air conditioner to change direction so as to control the air conditioner to enter the refrigeration mode again. Namely, after finishing the process of high-temperature sterilization, the air conditioner is continuously controlled to enter the cooling mode. Specifically, the four-way valve is controlled to change direction so as to control the air conditioner to enter the refrigeration mode again.
