Based on the hardware architecture, the embodiment of the air conditioner control method is provided.
Referring to fig. 2, fig. 2 is a diagram illustrating an embodiment of an air conditioner control method according to the present invention, the air conditioner control method includes the following steps:
step S10, obtaining condensation parameters of the air conditioner;
in the present invention, the air conditioner has a fresh air mode in which the air conditioner delivers outdoor air (fresh air) to the indoor, and, referring to fig. 3, the air conditioner includes: the fresh air device comprises a shell 10 and a fresh air device 20 arranged in the shell 10, wherein a fresh air port 110 is formed in at least one of a front panel 100 of the shell 10 and two end plates 200 of the shell 10, the fresh air device 20 is provided with an air inlet and an air outlet, the air inlet is communicated with the outside or the inside, and the air outlet is communicated with the fresh air port 110. Optionally, the fresh air device includes a volute, a centrifugal wind wheel and a motor for driving the centrifugal wind wheel to rotate, the volute has a wind cavity, and the centrifugal wind wheel is disposed in the wind cavity; the fresh air device further comprises a purification net arranged in the volute, the volute is provided with the air inlet and the air outlet, and the purification net is located between the air inlet and the air cavity.
Because the air-conditioning indoor unit provided by the application is provided with the fresh air device 20, the fresh air device 20 can introduce outdoor fresh air into a room, and therefore the quality of indoor air can be improved. Secondly, in the air-conditioning indoor unit provided by the present application, the fresh air opening 110 is formed in at least one of the front panel 100 of the casing 10 and the two end panels 200 of the casing 10, in other words, the fresh air opening 110 is not formed in the top plate of the casing 10, so that dust can be prevented from falling into the fresh air device 20 from the top of the casing 10, dust accumulation in the fresh air device 20 can be prevented, and the cleanliness of fresh air blown out by the fresh air device 20 can be improved; finally, the air intake of the indoor air conditioner is mostly arranged on the top plate, if the fresh air port 110 is arranged on the top plate, fresh air is easy to be sucked into the indoor air conditioner through the air intake of the indoor air conditioner, and dust in the interior of the indoor air conditioner is more, so that pollution to the fresh air can be caused.
In the invention, the air conditioner adopts the condensation parameter to represent the condensation risk of the air conditioner, and the condensation parameter can be obtained from at least one of the indoor environment temperature, the indoor environment humidity, the fresh air temperature, the fresh air speed and the outdoor environment temperature. For example, the indoor ambient temperature, the outdoor ambient temperature, and the indoor ambient humidity are used as condensation parameters, and the indoor ambient temperature, the outdoor ambient temperature, and the outdoor ambient humidity are obtained after the air conditioner is started; on this basis, the condensation parameter may also include a fresh air temperature, a fresh air humidity, and/or a fresh air fan speed. When the sensor is arranged on an outdoor unit or a fresh air pipe, the fresh air temperature is detected, and the outdoor environment temperature can be changed into the fresh air temperature.
In one embodiment, the condensation parameter can be calculated by the above parameters, specifically, when the air conditioner is in a refrigeration mode, the fresh air temperature is higher than the indoor environment temperature, condensation easily occurs on the inner wall of the fresh air pipeline, the air conditioner can calculate the fresh air dew point temperature according to the fresh air temperature and the fresh air humidity, and the fresh air dew point temperature is used as the condensation parameter; when the air conditioner is in the mode of heating, the new trend temperature is less than indoor environment temperature, and the outer wall that is located the wind channel of indoor environment produces the condensation easily, and the air conditioner calculates indoor environment dew point temperature according to indoor environment temperature and indoor environment humidity to regard indoor environment dew point temperature as the condensation parameter. Certainly, the humidity difference between the indoor environment humidity and the fresh air humidity can be calculated, and the humidity difference is used as a condensation parameter; or calculating the temperature difference between the indoor environment temperature and the fresh air temperature, and taking the temperature difference as a condensation parameter. When the condensation parameters are detected, the detection of fresh air humidity or outdoor environment humidity is reduced, only the indoor environment humidity is detected, the setting of a sensor is reduced, and the cost is saved.
Step S20, judging whether the condensation parameter meets the condensation condition;
the condensation condition is not necessarily determined singly according to a certain parameter or a combination of certain parameters, but may be determined according to one or more of the parameters, and after the condition is met, the condition is determined according to one or more of the other parameters, and when the conditions are met, the condensation condition is met. The condensation parameter is set according to different possible condensation conditions, for example, judgment is made according to the difference between the indoor environment temperature and the outdoor environment temperature, judgment is made on the indoor environment humidity according to the judgment result, and whether the condensation condition is met or not is judged when the indoor environment humidity is met.
In one embodiment, a condensation condition may be generated according to at least one of the parameters affecting condensation of the air conditioner, and whether the air conditioner is condensed or not may be determined according to the condensation condition. For example, in the air conditioner in the cooling mode, the condensation parameter is the fresh air dew point temperature, and the condensation condition is as follows: the dew point temperature of the fresh air is higher than the indoor temperature; in the heating mode of the air conditioner, the condensation parameter is the indoor dew point temperature, and the condensation condition is as follows: the indoor dew point temperature is higher than the fresh air temperature. In addition, when the condensation parameter is the temperature difference (the temperature difference between the indoor temperature and the fresh air temperature), the condensation condition is as follows: the temperature difference is greater than a preset temperature difference; when the condensation parameter is the humidity difference (the humidity difference of indoor humidity and fresh air humidity), the condensation condition is: the humidity difference is greater than the preset humidity difference.
Step S30, when the condensation parameter meets the condensation condition, the fresh air function of the air conditioner is closed;
the air conditioner judges whether the acquired condensation parameters meet the condensation conditions or not according to the set condensation conditions; for example, a difference between the indoor ambient temperature and the outdoor ambient temperature is calculated, and when the difference is smaller than a set value (for example, 5 degrees or 8 degrees), and the indoor humidity is greater than the set value, for example, the indoor humidity reaches 60% or 50%, it is determined that the condensation condition is satisfied; or, when the difference is smaller than a set value (for example, 10 degrees or 12 degrees) and larger than a previously set value (for example, 5 degrees or 8 degrees), and the indoor humidity is larger than a set value (for example, 30% or 40% of the indoor humidity), it is determined that the condensation condition is satisfied; still alternatively, when the indoor ambient temperature is greater than the outdoor ambient temperature, the indoor humidity is greater than a set value, for example, greater than 40% or 50%, and a difference between the indoor ambient temperature and the outdoor ambient temperature is greater than a set value, for example, greater than 2 degrees or 4 degrees, it is determined that the condensation condition is satisfied.
In one embodiment, the determination of the condensation condition may further be: and when the dew point temperature of the fresh air is higher than the indoor temperature, judging that the condensation condition is met.
After the condensation parameters meet the condensation conditions, the air conditioner can generate condensation risks, and the fresh air function is turned off, so that the air conditioner does not generate condensation.
In one embodiment, after the air conditioner does not meet the condensation condition, a condition difference value from the current time to the time when the condensation condition is met is determined; and determining an operation parameter adjustment value of the air conditioner according to the condition difference value, and adjusting the operation of the air conditioner according to the operation parameter adjustment value so as to enable the air conditioner to be in a non-condensation state. For example, when the difference between the current indoor environment humidity and the set value 50% is 20%, the operation parameters of the air conditioner are adjusted, for example, the indoor environment humidity is reduced, the indoor environment is dehumidified to reduce the environment humidity, or the difference between the indoor environment temperature and the outdoor environment temperature is reduced, so that condensation of the air conditioner can be avoided, the risk of condensation does not exist, the time that the air conditioner is in a non-condensation state can be prolonged, the time that fresh air is opened can be kept longer, and the indoor environment is better; and when the condition difference value reaches a preset condition difference value threshold value, judging that the condensation condition is met. Before reaching the condensation condition, the difference that allows some threshold values just judges in advance and satisfies the condensation condition when reaching this difference for the air conditioner does not produce any condensation and just ends the new trend, closes the new trend function, effectively avoids producing the condensation at the air conditioner more, brings the risk, guarantees the safety of air conditioner inner part, improves the life-span.
In the technical scheme that this embodiment provided, the air conditioner operation in-process, through the condensation parameter that acquires the air conditioner, when the condensation parameter satisfies the condensation condition, closes the new trend function to avoid the air conditioner to produce the condensation, guaranteed the life of air conditioner.

Calculating a difference between the indoor ambient temperature and the outdoor ambient temperature, and determining that the condensation condition is met when the difference is smaller than a set value (for example, 5 degrees or 8 degrees) and the indoor humidity is greater than the set value (for example, the indoor humidity reaches 60% or 50%); alternatively, when the difference is less than a set value (e.g., 10 degrees or 12 degrees) and greater than a previously set value (e.g., 5 degrees or 8 degrees), and the indoor humidity is greater than a set value (e.g., 30% or 40% of the indoor humidity), it is determined that the condensation condition is satisfied. This embodiment provides the judgement of more accurate air conditioner condensation condition through calculating the temperature difference delta T of indoor ambient temperature T1 and indoor ambient temperature T4 earlier, according to temperature difference delta T and indoor ambient humidity RH's judgement for the judgement of the risk of air conditioner condensation is more accurate, has effectively avoided the condensation of air conditioner.

step S36, when the difference value is larger than a second preset temperature value, judging whether the indoor environment humidity is larger than a third preset humidity value;
and step S37, when the indoor environment humidity is larger than a third preset humidity value, determining that the condensation condition is met.
After calculating a temperature difference Δ T between the indoor ambient temperature T1 and the outdoor ambient temperature T4, comparing the temperature difference Δ T with a first preset temperature value, where the first preset temperature value is set according to a requirement, and may be, for example, 2 degrees, 4 degrees, or 5 degrees; when the difference is smaller than or equal to a first preset temperature value, judging whether the indoor environment humidity RH is larger than a first preset humidity value, wherein the first preset humidity value is set according to requirements, for example, the first preset humidity value can be 60% or 70%, and when the indoor environment humidity RH is larger than the preset humidity value, judging that a condensation condition is met; and when the indoor environment humidity RH is smaller than a first preset humidity value, judging that the condensation condition is not met, continuously detecting the values of the indoor environment temperature T1, the outdoor environment temperature T4 and the indoor environment humidity RH, and detecting whether the condensation condition is met.
