Based on the hardware structure shown in fig. 1, a first embodiment of the present invention provides a control method of an air conditioner.
Referring to fig. 2, fig. 2 is a flowchart illustrating a control method of an air conditioner according to a first embodiment of the present invention.
The embodiments of the present invention provide embodiments of a control method of an air conditioner, and it should be noted that although a logic sequence is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that shown or described herein. Specifically, the control method of the air conditioner of the embodiment includes:
Step S10: when the air conditioner operates in a first preset no-wind-sense state, acquiring a first indoor temperature and a first indoor humidity of an indoor environment where the air conditioner is positioned, and acquiring a first set temperature of the air conditioner;
It should be noted that, the control method of the air conditioner provided by the present invention is applied to an air conditioner, which has a function of no wind sensation, where in this embodiment, the air conditioner may be controlled to operate in a state of no wind sensation based on a wind sensation instruction output by a user, and the air conditioner may be controlled to automatically switch to operate in a state of no wind sensation based on external parameters of the air conditioner (such as an indoor temperature of an outdoor environment where the air conditioner is located, a set temperature of the air conditioner, etc.), which is not limited in this embodiment.
Specifically, the first preset no-wind state may be a no-wind state corresponding to a specific operation parameter, which is set by a user or a developer in a user-defined manner, for example, the first preset no-wind state is that an operation frequency of the air conditioner is f, an operation speed of an indoor fan of the air conditioner is n, a wind guard angle of the air conditioner is α, and other internal components of the air conditioner are no-wind states of a specific operation parameter, in addition, in order to improve flexibility of operation of the air conditioner, the first preset no-wind state may also be a corresponding no-wind state satisfying a specific operation state parameter, specifically, in this embodiment, the first preset no-wind state refers to a no-wind state that makes an air flow speed of an indoor environment where the air conditioner is less than or equal to a preset speed, and a corresponding wind-blowing index of the air conditioner is less than or equal to a preset index, where, it should be noted that, the preset index refers to a corresponding air-blowing index in a non-wind-sensation state, the air-blowing sensation is a discomfort feeling frequently complained about by people in the air-conditioning environment, and the air-blowing index refers to a percentage of dissatisfied people caused by the air-blowing sensation, specifically, in this embodiment, by calculating the air-blowing index according to the indoor temperature of the indoor environment in which the air conditioner is located, the turbulence intensity and the wind speed corresponding to the indoor fan of the air conditioner, it is easy to understand that the turbulence intensity refers to the degree of time and space variation of the wind speed blown out by the air conditioner, wherein the turbulence intensity is related to the wind shield of the air conditioner, so that the operation parameters of the air conditioner, such as the operation frequency, the wind speed or the wind shield of the air conditioner, etc., can be flexibly regulated based on the actual state, only the air flow speed of the indoor environment in which the air conditioner is located is required to be less than or equal to the preset speed, and the air-feeling index corresponding to the air conditioner is smaller than or equal to the preset index.
In addition, it is easy to understand that, since the air conditioner in this embodiment has at least two types of non-wind-sensation states, in which the operation state parameters corresponding to the various non-wind-sensation states are different, in order to distinguish the various non-wind-sensation states, in this embodiment, the first and second etc. are used to distinguish the various non-wind-sensation states and the operation state parameters corresponding to the various non-wind-sensation states, for example, the first preset non-wind-sensation state and the second preset non-wind-sensation state are included in this embodiment, in which the second preset non-wind-sensation state refers to the non-wind-sensation state that the air flow speed of the indoor environment where the air conditioner is located is less than or equal to the first preset speed, and the wind-sensation index corresponding to the air conditioner is less than or equal to the first preset index, and the first preset non-wind-sensation state refers to the air flow speed of the indoor environment where the air conditioner is located is less than or equal to the second preset speed, and the air conditioner has a corresponding air-blowing index smaller than or equal to a second preset index, wherein the second preset index is larger than the first preset index, the first preset speed is between 0.1r/S and 0.8r/S, the second preset speed is between 0.1r/S and 0.8r/S, the first preset index is 5% to 20%, the second preset index is 0 to 8%, if the first preset air-feeling-free state indicates that the air flow speed of the indoor environment where the air conditioner is located is smaller than or equal to 0.2r/S, the air-blowing index corresponding to the air conditioner is smaller than or equal to 5%, the second preset air-feeling-free state indicates that the air flow speed of the indoor environment where the air conditioner is located is smaller than or equal to 0.8r/S, and the air-blowing index corresponding to the air conditioner is smaller than or equal to 20%.
In some embodiments, after the air conditioner enters the operation without wind sensing state, the condensation phenomenon may occur at the air outlet, so in this embodiment, in order to solve the technical problem that the condensation phenomenon occurs when the current air conditioning system operates in the operation without wind sensing state, when the air conditioner operates in the first preset operation without wind sensing state, the first indoor temperature and the first indoor humidity of the indoor environment where the air conditioner is located are obtained, and the first set temperature of the air conditioner is obtained, so that whether the anti-condensation treatment needs to be performed on the air conditioner is monitored in real time through the first indoor temperature, the first indoor humidity and the first set temperature.
In addition, the air conditioner includes three operation states, namely a rapid cooling state, an excessive state and a steady operation state when the air conditioner is operated in a non-wind state, wherein the three operation states of the non-wind state are distinguished according to the change rate of the external parameter of the air conditioner, for example, the three operation states are distinguished according to the temperature change rate of the indoor temperature of the indoor environment in unit time, so in the embodiment, in order to improve the accuracy of the condensation prevention treatment on the air conditioner through the first indoor temperature, the first indoor humidity and the first set temperature, the first indoor humidity and the first set temperature of the air conditioner are obtained, wherein the first indoor temperature, the first indoor humidity and the first set temperature of the indoor environment of the air conditioner are corresponding to the air conditioner in the operation state corresponding to the steady operation state when the air conditioner is operated in the first preset non-wind state.
Step S20: determining a temperature difference between the first indoor temperature and the first set temperature;
step S30: judging whether the temperature difference and the first indoor humidity meet preset condensation conditions or not;
Step S40: and if the preset condensation condition is met, adjusting the operation parameters of the air conditioner to prevent the air conditioner from condensation.
Specifically, the preset condensation condition refers to that when the temperature difference between the indoor temperature of the indoor environment where the air conditioner is located and the set temperature of the air conditioner reaches a certain specific temperature difference under a certain specific indoor humidity condition, the air conditioner generates condensation phenomenon,
Therefore, in this embodiment, after obtaining the first indoor temperature of the indoor environment where the air conditioner is located, the first indoor humidity and the temperature difference of the first set temperature of the air conditioner, optionally, determining the critical temperature difference corresponding to the first indoor humidity based on the preset humidity-temperature difference mapping function, then determining the temperature difference between the first indoor temperature and the first set temperature, and judging whether the temperature difference exceeds the critical temperature difference corresponding to the first indoor humidity, if so, judging that the preset condensation condition is met, and finally adjusting the operation parameters of the air conditioner to prevent the air conditioner from condensation.
Specifically, in this embodiment, when the first indoor humidity of the indoor environment where the air conditioner is located is detected to be greater than or equal to the first preset humidity and less than or equal to the second preset humidity, it is determined that the preset condensation condition is met after the temperature difference is detected to be less than or equal to the temperature difference threshold, where the first preset humidity, the second preset humidity and the temperature difference threshold are all preset limiting values, for example, the first preset humidity is between 75% and 80%, the second preset humidity is between 80% and 90%, the temperature difference threshold is between 3 ℃ and 5 ℃, it is easy to understand that when the indoor humidity of the indoor environment is very high, the set temperature of the air conditioner and the indoor temperature of the indoor environment where the air conditioner is located are not great, which indicates that the air conditioner will appear condensation after continuing to run for a long time in the environment state, in this embodiment, when the temperature difference and the first indoor humidity preset condensation condition are detected, it is determined whether the duration of the current air conditioner running in the first preset non-air-sensing state reaches the preset time, if the preset running time reaches the preset time is between 75%, and if the preset running time reaches the preset time is not, the preset time is set to prevent the air conditioner from reaching the preset time, and if the preset running time reaches the preset time is set time, and the preset time is set to prevent the air conditioner from reaching the preset time, and the user from reaching the preset time.
In addition, in some embodiments, the operation frequency of the air conditioner, the wind speed of the indoor fan of the air conditioner and the baffle parameters of the air conditioner are adjusted to prevent the air conditioner from condensation, further, in order to avoid affecting the blowing index of the air conditioner, preferably, the operation frequency of the air conditioner is firstly adjusted and controlled, if the compressor frequency is firstly reduced to improve the evaporation temperature, if the compressor frequency is still in a condensation state or a condensation trend when the compressor frequency is reduced to the limit frequency, the operation frequency of the air conditioner, the wind speed of the indoor fan of the air conditioner and the baffle parameters of the air conditioner are coordinated to prevent the air conditioner from condensation, and in order to facilitate understanding, in this embodiment, the operation frequency of the air conditioner, the wind speed of the indoor fan of the air conditioner and the baffle parameters of the air conditioner are coordinated to prevent the air conditioner from condensation:
Determining a wind shielding angle when the current air conditioner operates in a first preset no-wind-sensation state, acquiring the working time of the current air conditioner operating in the first preset no-wind-sensation state, determining the wind speed grade of the current air conditioner, determining the rotating speed of a fan according to the wind speed grade of the current air conditioner, controlling the fan of the air conditioner to operate at the rotating speed, and finally adjusting the working frequency according to the wind shielding angle, the rotating speed of the fan, the indoor temperature of the indoor environment where the air conditioner is located and the working time of the first preset no-wind-sensation state operation, wherein the air conditioning frequency is determined according to the operation parameters of the air conditioner and combined with the indoor temperature, so that the risk of condensation when the air conditioner operates is reduced.
It should be understood that the foregoing is merely illustrative, and the technical solution of the present invention is not limited in any way, and those skilled in the art may perform the arrangement according to the needs in practical application, and are not listed here.
According to the scheme, when the air conditioner operates in the first preset no-wind-sensation state, the first indoor temperature and the first indoor humidity of the indoor environment where the air conditioner is located are obtained, and the first set temperature of the air conditioner is obtained; determining a temperature difference between the first indoor temperature and the first set temperature; judging whether the temperature difference and the first indoor humidity meet preset condensation conditions or not; if the preset condensation condition is met, the operation parameters of the air conditioner are adjusted to prevent the air conditioner from condensation, so that the operation parameters of the air conditioner are timely adjusted when the air conditioner meets the preset condensation condition through the air conditioner external parameters by acquiring the air conditioner external parameters when the air conditioner operates in a preset windless state, and the air conditioner is prevented from condensation, so that the comfort level of a user is improved.
Further, based on the first embodiment of the control method of the air conditioner of the present invention, a second embodiment of the control method of the air conditioner of the present invention is provided.
Referring to fig. 3, fig. 3 is a flowchart illustrating a control method of an air conditioner according to a second embodiment of the present invention;
The second embodiment of the control method of an air conditioner is different from the first embodiment of the control method of an air conditioner in that, before the step of operating the air conditioner in the first preset no-wind state, the method further includes:
Step S101: when a windless operation instruction is received, acquiring a second indoor temperature and a second indoor humidity of an indoor environment where the air conditioner is positioned, and acquiring a second set temperature of the air conditioner;
Step S102: and if the second indoor temperature, the second indoor humidity and the second set temperature meet the first preset operation parameter condition, controlling the air conditioner to operate in a first preset windless state.
