Optionally, in the cooling process of the air conditioner, the indoor environment temperature is gradually reduced along with the cooling time, and when the indoor environment temperature reaches the set temperature, the air conditioner is stopped because the minimum cooling output of the indoor unit of the air conditioner is greater than the heat load of the indoor space. Therefore, during the operation of the air conditioner, the temperature rise treatment is performed under certain conditions, such as adjusting the throttling component, or reducing the operation frequency of the compressor.
Optionally, in an embodiment, when the air conditioner operates in a cooling mode, 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 that cooling output of the air conditioner is reduced.
Optionally, in another embodiment, when a temperature difference between an indoor ambient temperature and a set temperature of the air conditioner is smaller than a first preset temperature difference, a throttling component of the air conditioner is adjusted, and when the temperature difference between the indoor ambient temperature and the set temperature of the air conditioner is still smaller than the first preset temperature difference, an opening degree of an air guide strip of the air conditioner is reduced, so as to reduce a cooling output of the air conditioner.
Optionally, in another embodiment, when a temperature difference between an indoor ambient temperature and a set temperature of the air conditioner is smaller than a first preset temperature difference and a parameter of the throttling component satisfies a preset condition, the opening degree of the air guide strip of the air conditioner is reduced, and the air output of the air guide strip 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, 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 cooling output of the air conditioner.
Optionally, in another embodiment, when the throttling component is an electronic expansion valve, the opening degree of the electronic expansion valve is reduced to increase the temperature of the indoor heat exchanger, thereby reducing the cooling output of the air conditioner.
Optionally, in an embodiment, a decrease amount for decreasing the opening degree of the electronic expansion valve is determined according to a temperature difference between the indoor ambient temperature and the set temperature, and the opening degree of the electronic expansion valve is decreased according to the decrease amount, for example, when the first temperature difference is 4 ℃ and the opening degree of the electronic expansion valve is 100 steps, the decrease amount is determined to be 40 steps, the opening degree of the electronic expansion valve is decreased to 60 steps, the opening degree of the electronic expansion valve is directly decreased once according to the first temperature difference, the temperature of the indoor heat exchanger is raised, and thus a situation that the air conditioner is stopped is avoided, but a situation that the temperature of the indoor heat exchanger is raised quickly due to an excessively large decrease amount is likely to occur.
Optionally, in another embodiment, a decreasing amount for decreasing the opening degree of the electronic expansion valve is determined according to a temperature difference between the indoor ambient temperature and the set temperature, the opening degree of the primary electronic expansion valve is decreased according to the decreasing amount, a variation of the temperature difference between the indoor ambient temperature and the set temperature is obtained, an adjustment amount for the decreasing amount is determined according to the variation, the decreasing amount is adjusted according to the adjustment amount, and the method returns to the executing step: and according to the reduction amount, reducing the opening degree of the primary electronic expansion valve 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 degree of the electronic expansion valve is 100 steps, determining the reduction amount to be 20 steps, reducing the opening degree of the electronic expansion valve to 80 steps, increasing the temperature difference to 4 ℃, the variation to 1 ℃, determining the adjustment amount of the reduction amount to be 10, reducing the opening degree to 30 steps, reducing the opening degree of the electronic expansion valve to 50 steps, monitoring the temperature difference between the indoor environment temperature and the set temperature in real time, adjusting the reduction amount, further adjusting the opening degree of the electronic expansion valve, and avoiding the situation that the temperature of the indoor heat exchanger is rapidly increased when the opening degree of the electronic expansion valve is reduced at one step, so that the indoor environment temperature fluctuates greatly.
Optionally, in another embodiment, after the opening degree of the primary electronic expansion valve is decreased, a temperature difference between the indoor ambient temperature and the set temperature is obtained, and when the temperature difference is still smaller than a first preset temperature difference, the method returns to the step of: the opening degree of the primary electronic expansion valve is reduced until the temperature difference value is larger than or equal to a first preset temperature difference value, the temperature difference value between the indoor environment temperature and the set temperature is monitored in real time, the opening degree of the electronic expansion valve is gradually reduced according to the monitoring result, and the situation that the temperature of the indoor heat exchanger is rapidly increased and the fluctuation of the indoor environment temperature is overlarge when the opening degree of the electronic expansion valve is reduced at one time is avoided.
Optionally, in an embodiment, when the first temperature difference is smaller than a first preset temperature difference, the opening degree of the small air guide strip is reduced.
It is easy to understand that when the indoor environment temperature is low, only the opening degree of the small air guide strips is adjusted to be low, and the reduction amount of the refrigeration output of the air conditioner is too small, so that the situation that the indoor unit of the air conditioner is likely to generate temperature-reaching shutdown of the air conditioner because the minimum refrigeration output is still larger than the heat load of the indoor space where the air conditioner is located is easy to occur.
Optionally, in another embodiment, when the first temperature difference is smaller than a first preset temperature difference, the opening degree of the large wind guide strip is reduced.
It can be easily understood that, when the indoor environment temperature is lower, only adjust the aperture of big wind-guiding strip, appear easily because the reduction undersize of the refrigeration output of air conditioner, thereby appear the air conditioner internal unit probably because the minimum refrigeration output still is greater than the condition of the heat load of air conditioner place indoor space, and then lead to the air conditioner to take place to reach the warm shutdown, or, appear easily because the aperture of the big wind-guiding strip of direct adjustment, the reduction that leads to the refrigeration output of air conditioner is too big, thereby the refrigeration output that leads to the air conditioner is too low, lead to indoor environment temperature to rise fast, lead to the refrigeration effect of air conditioner poor.
Optionally, in order to solve the problem that the air conditioner may be shut down due to the fact that the minimum cooling output of the air conditioner is still greater than the thermal load of the indoor space where the air conditioner is located, because the reduction of the cooling output of the air conditioner is too small, in another embodiment, when the first temperature difference is smaller than a first preset temperature difference, the opening of the small air guiding strips is reduced, and the opening of the large air guiding strips is reduced.
It is easy to understand that, when the opening degree of the small air guiding strips is adjusted down and the opening degree of the large air guiding strips is adjusted down, the algorithm logic is complex, and the situation that the reduction amount of the refrigeration output of the air conditioner is too small due to adjustment errors easily occurs.
Optionally, in order to solve the above problem that adjustment errors are likely to occur due to a complex algorithm logic when the opening degrees of the small air guide strips and the large air guide strips are adjusted simultaneously, in another embodiment, when the first temperature difference is smaller than a first preset temperature difference, the opening degrees of the small air guide strips are reduced, and whether a second temperature difference between the indoor environment temperature and the set temperature of the air conditioner is smaller than the first preset temperature difference is dynamically detected; when the second temperature difference value is smaller than the first preset temperature difference value, the opening degree of the small air guide strip is reduced until the small air guide strip is closed; after the opening degree of the large air guide strips is reduced, dynamically detecting whether a third temperature difference value between the set temperatures of the air conditioner and the indoor environment temperature is smaller than a second preset temperature difference value, wherein the second preset temperature difference value is smaller than or equal to the first preset temperature difference value; when the third temperature difference is less than the second preset temperature difference, the opening of the large air guide strip is reduced until the large air guide strip is closed, the small air guide strip and the large air guide strip are gradually adjusted, so that the adjustment logic is clear, the process is advanced layer by layer, and the condition that the indoor environment temperature is too large is easily generated when the large air guide strip is directly adjusted at one time, so that the technical defect that the refrigeration effect of the air conditioner is poor is caused, and the refrigeration effect of the air conditioner is optimized under the condition that the air conditioner is not stopped due to the fact that the air conditioner is not warmed.
