Optionally, during the refrigerating process of the air conditioner, the indoor environment temperature can be gradually reduced along with the refrigerating duration, and when the indoor environment temperature reaches the set temperature, the air conditioner is stopped because the minimum refrigerating output of the indoor unit of the air conditioner is larger than the heat load of the indoor space. Therefore, the air conditioner may perform a temperature increasing process such as adjusting a throttle member or reducing an operation frequency of the compressor under a certain condition during the operation.
Optionally, in an embodiment, when the air conditioner is in refrigeration operation, an indoor environment temperature where the air conditioner is located is obtained, a first temperature difference between the indoor environment temperature and a set temperature of the air conditioner is determined, and when the first temperature difference is smaller than a first preset temperature difference, the opening degree of an air guide strip of the air conditioner is reduced so as to reduce refrigeration output of the air conditioner.

Optionally, in another embodiment, when the temperature difference between the indoor environment temperature and the set temperature of the air conditioner is smaller than the first preset temperature difference and the parameter of the throttling component meets the preset condition, the opening of the air guiding strip of the air conditioner is reduced, the air outlet quantity of the air guiding strip is reduced, and therefore the temperature of the indoor heat exchanger is increased, and then the refrigeration output of the air conditioner is reduced.
Optionally, in an embodiment, when the throttling component is a capillary tube, the length of the capillary tube is shortened and/or the inner diameter of the capillary tube is increased, so that the pressure drop of the refrigerant passing through the capillary tube is reduced, thereby increasing the temperature of the indoor heat exchanger and further reducing the refrigeration output of the air conditioner.
Optionally, in another embodiment, when the throttling component is an electronic expansion valve, the opening of the electronic expansion valve is reduced, so that the temperature of the indoor heat exchanger is increased, and the refrigeration output of the air conditioner is reduced.
Optionally, in an embodiment, the reducing amount of the opening of the electronic expansion valve is determined according to the temperature difference between the indoor environment temperature and the set temperature, and when the opening of the electronic expansion valve is determined to be 40 steps according to the reducing amount, for example, the first temperature difference is 4 ℃, and the opening of the electronic expansion valve is 100 steps, the opening of the electronic expansion valve is reduced to 60 steps, and the opening of the electronic expansion valve is directly reduced at one time according to the first temperature difference, so that the temperature of the indoor heat exchanger is raised, and further, the condition that the air conditioner is stopped is avoided, but the condition that the temperature of the indoor heat exchanger is quickly raised due to the excessive reducing amount easily occurs.
Optionally, in another embodiment, the step of adjusting the opening of the electronic expansion valve down is determined according to a temperature difference between the indoor environment temperature and the set temperature, the change of the temperature difference between the indoor environment temperature and the set temperature is obtained by adjusting the opening of the electronic expansion valve down according to the step of adjusting the opening of the electronic expansion valve down, the adjustment of the step of adjusting the electronic expansion valve down according to the change is performed by: according to the lowering amount, the opening of the primary electronic expansion valve is lowered until the temperature difference is greater than or equal to a first preset temperature difference, for example, the first temperature difference is 3 ℃, the opening of the electronic expansion valve is 100 steps, the lowering amount is determined to be 20 steps, the opening of the electronic expansion valve is lowered to 80 steps, the temperature difference is raised to 4 ℃, the change amount is 1 ℃, the adjusting amount of the lowering amount is determined to be 10, the lowering amount is 30, the opening of the electronic expansion valve is lowered to 50 steps, the lowering amount is adjusted by monitoring the temperature difference between the indoor environment temperature and the set temperature in real time, the opening of the electronic expansion valve is further adjusted, and the situation that the indoor environment temperature fluctuation is overlarge due to the fact that the indoor heat exchanger temperature is rapidly raised when the opening of the electronic expansion valve is lowered once is avoided.
Optionally, in another embodiment, after the opening of the primary electronic expansion valve is adjusted down, a temperature difference between the indoor ambient temperature and the set temperature is obtained, and when the temperature difference is still smaller than the first preset temperature difference, the execution returns to the step of: the opening of the primary electronic expansion valve is regulated down until the temperature difference value is larger than or equal to the first preset temperature difference value, the opening of the electronic expansion valve is gradually regulated down according to the monitoring result by monitoring the temperature difference value between the indoor environment temperature and the set temperature in real time, and the situation that the indoor environment temperature fluctuation is overlarge due to the fact that the indoor heat exchanger temperature is rapidly increased when the opening of the electronic expansion valve is regulated down once is avoided.

It is easy to understand that when the indoor environment temperature is low, only the opening degree of the small air guide strip is adjusted down, and the reduction of the refrigeration output of the air conditioner is too small, so that the situation that the minimum refrigeration output of the air conditioner is still larger than the heat load of the indoor space where the air conditioner is located is easy to occur, and the air conditioner is caused to generate Wen Tingji.
Optionally, in another embodiment, when the first temperature difference is smaller than a first preset temperature difference, the opening of the large air guiding strip is reduced.
It is easy to understand that when the indoor environment temperature is lower, only the opening of the large air guide strip is adjusted, the reduction of the refrigerating output of the air conditioner is easy to occur, so that the condition that the minimum refrigerating output is still larger than the heat load of the indoor space where the air conditioner is located is likely to occur, and further the air conditioner is caused to stop when reaching the temperature, or the reduction of the refrigerating output of the air conditioner is easy to occur due to the fact that the opening of the large air guide strip is directly adjusted, so that the refrigerating output of the air conditioner is too low, the indoor environment temperature is caused to rise rapidly, and the refrigerating effect of the air conditioner is poor.
Optionally, in order to solve the above problem that the reduction of the cooling output of the air conditioner is too small, so that the situation that the minimum cooling output of the air conditioner is still greater than the heat load of the indoor space where the air conditioner is located may easily occur, and further the air conditioner is stopped when reaching the temperature, in still another embodiment, when the first temperature difference is smaller than the first preset temperature difference, the opening of the small air guiding strip is reduced, and the opening of the large air guiding strip is reduced.
It is easy to understand that when the opening degree of the small air guide strip is adjusted down and the opening degree of the large air guide strip is adjusted down, the algorithm logic is complex, and the situation that the adjustment error easily occurs so that the reduction of the refrigerating output of the air conditioner is too small is easy to occur.
