Detailed Description
The invention firstly provides a control method of an air conditioner, which comprises the following steps:
after the air conditioner is started, acquiring the humidity change rate of the indoor environment where the air conditioner is located according to a preset first time period;
when the humidity change rate is smaller than or equal to a preset humidity change threshold value, controlling the air conditioner to operate according to the working condition of a laboratory; and when the humidity change rate is larger than a preset humidity change threshold value, controlling the air conditioner to operate according to the household working condition.
Fig. 1 is a schematic flowchart of a control method of an air conditioner according to an embodiment of the present invention. Referring to fig. 1, the control method of the present invention specifically includes:
step S10, after the air conditioner is started, acquiring the humidity change rate of the indoor environment where the air conditioner is located;
step S20, judging whether the humidity change rate is less than or equal to a preset humidity change threshold value; if yes, go to step S30; if not, go to step S40;
step S30, controlling the air conditioner to operate according to the laboratory working condition;
and step S40, controlling the air conditioner to operate according to the household working condition.
In a normal home environment, the temperature and humidity of the indoor environment gradually decrease as the air conditioner performs a cooling operation. However, in the laboratory environment of the condensation experiment, the humidity and temperature values can be stabilized through equipment, and the humidity of the current condensation test standard is basically maintained between 80% and 90% under three working conditions. Therefore, the invention judges whether the air conditioner is in a normal household environment or a laboratory environment according to the humidity change rate within a period of time after the air conditioner is started, thereby adopting different operation modes under two different environments. Specifically, when the humidity change rate is small, the environment where the air conditioner is located is a laboratory environment, and the air conditioner can be controlled to operate according to the working condition of the laboratory at the moment; when the humidity change rate is larger, the environment where the air conditioner is located is a normal household environment, and the air conditioner can be controlled to operate according to the household working condition. Therefore, the normal operation of the air conditioner in a household environment is ensured, and the condensation test can be performed in a laboratory environment.
Further, the control method of the present invention further includes: and under the household working condition, controlling the air conditioner to operate according to the operating parameters corresponding to the actual humidity of the current indoor environment, wherein the operating parameters comprise the operating frequency of a compressor of the air conditioner. That is, in the domestic situation, in order to ensure the qualified condensation of the air conditioner, the air conditioner operating parameters corresponding to different environmental humidity values are different. Since the operation of the air conditioner is known or readily available to those skilled in the art under home operating conditions, it is not described herein in detail.
In some embodiments, the control method of the present invention further comprises: under the working condition of a laboratory and on the premise that the condensation condition of the air conditioner is qualified, the air conditioner is enabled to sequentially operate according to the operation parameters corresponding to a plurality of humidity thresholds which are gradually reduced under the working condition of a household; wherein the operating parameter of the air conditioner comprises an operating frequency of a compressor of the air conditioner.
Under the laboratory operating mode, under the prerequisite of guaranteeing that the air conditioner condensation condition is qualified, make the air conditioner operate in proper order with the operating parameter that a plurality of humidity threshold values that reduce gradually under the domestic operating mode correspond, can find the critical value that guarantees the qualified air conditioner operating parameter of condensation under the invariable condition of humidity (the humidity of laboratory environment is roughly constant) to sacrifice refrigeration effect as far as possible, promoted refrigeration effect. The intelligent verification mode does not need research personnel to stop, change parameters and verify once and once, is simple, convenient and quick, and has higher efficiency and accuracy.
For example, the humidity of the laboratory environment is constantly maintained at about 90%, and the air conditioner operating parameters under the corresponding household working condition under the humidity may be, for example, a wind speed of 1200 rpm and an operating frequency of a compressor of 40Hz, at which time the condensation condition of the air conditioner is qualified. In a laboratory environment, if only humidity is taken as a judgment basis, the air conditioner only operates the parameters of wind speed 1200 revolutions per minute and operating frequency 40Hz of the compressor, which actually sacrifice the refrigeration effect and only operates the part. In the invention, when the humidity of the laboratory environment is kept constant at about 90%, the air conditioner is operated by using the operating parameters (such as the wind speed of 1150 revolutions per minute and the operating frequency of the compressor of 45Hz) corresponding to the humidity of 70% in the household environment, whether the air conditioner can be qualified or not is judged, and if the air conditioner can still be qualified, the actual household operating parameters can be changed, so that the refrigerating effect is improved.
Fig. 2 is a schematic flow chart of a control method according to a further embodiment of the invention. Referring to fig. 2, in some embodiments, the step S30 may specifically include:
step S301, enabling the air conditioner to operate for a first preset time according to operation parameters corresponding to the condition that the humidity of the air conditioner is greater than or equal to a first humidity threshold value under a household working condition;

step S303, enabling the air conditioner to operate according to the corresponding operation parameters when the humidity is smaller than a first humidity threshold value and larger than a second humidity threshold value under the household working condition;
and step S304, reducing the operation frequency of the compressor on the basis of the corresponding operation parameters when the humidity is more than or equal to the first humidity threshold value under the household condition. And returning to the step S303 to judge whether the condensation condition of the air conditioner is qualified again after the operating frequency of the compressor is reduced, and enabling the air conditioner to operate according to the corresponding operating parameters when the humidity of the air conditioner is smaller than the first humidity threshold value and larger than the second humidity threshold value under the household working condition until the condensation condition of the air conditioner is qualified.
In some embodiments, the step S30 further includes, under the laboratory conditions:
step S305, when the humidity of the air conditioner is smaller than the first humidity threshold value and larger than the second humidity threshold value under the household working condition, the corresponding operation parameter runs for a second preset time period, and then whether the condensation condition of the air conditioner is qualified is judged; if yes, go to step S306; if not, go to step S307;
step S306, the air conditioner is enabled to operate according to the corresponding operation parameters when the humidity is smaller than or equal to the second humidity threshold value under the household working condition;
and step S307, reducing the operation frequency of the compressor on the basis of the corresponding operation parameters when the humidity is smaller than the first humidity threshold and larger than the second humidity threshold under the household condition. And when the operating frequency of the compressor is reduced, returning to the step S305 to judge whether the condensation condition of the air conditioner is qualified again, and enabling the air conditioner to operate according to the corresponding operating parameters when the humidity is smaller than or equal to the second humidity threshold value under the household working condition until the condensation condition of the air conditioner is qualified.
In some embodiments, the step S30 further includes, under the laboratory conditions:
step S308, when the air conditioner operates for a third preset time according to the corresponding operating parameter when the humidity of the air conditioner is smaller than or equal to the second humidity threshold value under the household working condition, judging whether the condensation condition of the air conditioner is qualified; if yes, go to step S309; if not, go to step S310;

and step S310, reducing the operation frequency of the compressor on the basis of the corresponding operation parameters when the humidity is less than or equal to the second humidity threshold value under the household condition. And after the operating frequency of the compressor is reduced, returning to the step S308 to judge whether the condensation condition of the air conditioner is qualified again, and continuing to operate the air conditioner according to the current operating parameters and observing the condensation condition of the air conditioner until the condensation condition of the air conditioner is qualified.
Further, the step S30 includes:
step S311, judging whether a first time period for acquiring the humidity change rate is reached; if yes, go to step S10 to obtain the humidity change rate again; if not, turning to step S309, continuing to operate the air conditioner with the operation parameter corresponding to the humidity less than or equal to the second humidity threshold value under the household working condition, and continuing to observe the condensation condition of the air conditioner.
The invention particularly sets a first time period for acquiring the humidity change rate, and can avoid that the air conditioner is always circulated in a laboratory working condition under the household working condition due to judgment and detection errors or other factors.
Under the working condition of a laboratory, if the condensation condition of the air conditioner after running according to the running parameters corresponding to the certain humidity threshold under the household working condition is unqualified, the running frequency of the compressor can be reduced on the basis of the parameters until the condensation condition is qualified, and the qualified conditions of the condensation experiment under the experimental working condition are increased.

In other embodiments, the rate of change of humidity may also be obtained by:
in a first time period, acquiring the humidity of the indoor environment where the air conditioner is located n times according to a preset second time period, and recording the humidity as Th0、Th1、Th2……Thn；

The humidity change rate is calculated by the following formula: n ═ (Tav)m-Tav0)/Tav0(ii) a Wherein N represents a humidity change rate.
The judgment method of the humidity change rate obtains a plurality of groups of humidity values, stores the average value of each group of humidity values, judges by using the ratio of the difference between the last average value and the initial average value in a certain time, has long crossing time and slightly high precision judgment.
In still other embodiments, the rate of change of humidity may also be obtained by:
in the first time period, acquiring the humidity of the indoor environment where the air conditioner is located n times according to a preset fourth time period, and recording the humidity as Th0、Th1、Th2、……、Thn；
Obtaining the average value Tav of the humidity of the indoor environment where the air conditioner is located obtained n times, wherein the Tav is (Th)0+Th1+Th2+……+Thn)/n；
Sequentially taking m humidity average values according to the time sequence, and respectively recording as Tav0、Tav1、Tav2、……、Tavm；
The humidity change rate is calculated by the following formula: n ═ (Tav)0+Tav1+Tav2+……+Tavm-mTav0)/Tav0(ii) a Wherein N represents a humidity change rate.
The judgment method of the humidity change rate obtains m groups of humidity values, stores the average value of each group of humidity values, makes the difference between the sum of the average values of each group of humidity values and the m of the initial average value, and then makes the ratio of the difference value and the initial average value to judge, wherein the crossing time is long, and the precision judgment is highest.
