Description
Technical Field
The invention relates to the technical field of air conditioners, in particular to a control method and a control device of an air conditioner and the air conditioner.
Background
At present, commercial central air conditioners are widely applied to public places such as offices and the like, each user can control part of indoor units through a remote controller or a mobile phone, if the temperature is set unreasonably, the power consumption of the air conditioners can be increased, and further resource waste can be caused, and the current research shows that in summer, the temperature is increased by 1 ℃ every time, and the energy of the air conditioners can be saved by about 5-7%; if the air conditioner runs at a high power for a long time, the service life of the air conditioner is seriously influenced, for example, in summer, if the temperature set by the air conditioner in a refrigeration mode is 16 ℃, the indoor and outdoor temperature difference is too large, and a user is in an environment with a low temperature for a long time, and the user experience is also influenced. However, under the background of the strong demand for energy conservation in China, the energy conservation of the air conditioner is very important, and suggestions that the set temperature of the air conditioner is not lower than a recommended value are advocated nationwide in 2020, for example, a refrigeration recommended user sets 26-28 ℃, but in the prior art, the compensation value of the indoor return air temperature and the set temperature of the user is fixed, and the user generally has the idea that the lower the set temperature is, the faster the temperature is reduced. When the set temperature is lower, for example, 22 ℃, if the capacity requirement is calculated according to the fixed compensation value and the temperature is reached, energy waste and cold health hazards caused by the fact that a client cannot adjust the set temperature to be high in time are caused.
However, in the prior art, the control of the air conditioner during the cooling or heating operation generally has a mapping relationship between the temperature set by the user and the temperature-reaching shutdown temperature and the temperature-returning startup temperature, when the user sets a certain temperature, the temperature measuring point near the air-conditioning air return inlet can measure the room return air temperature in real time or at regular time, and compare the temperature with the temperature-reaching shutdown temperature in the mapping relationship, taking cooling as an example, if the return air temperature is reduced to or below the temperature-reaching shutdown temperature, the compressor is stopped to keep the inner fan to continue to operate. When the return air temperature rises to be higher than the starting temperature, the compressor is started to operate again. Such a room is frequently started at intervals while the temperature fluctuation is stabilized. However, the start-up interval of the compressor cannot be too small, and too frequent start-up and stop are disadvantageous to the long-term reliability of the compressor and the entire air-conditioning refrigeration system. The reason why the time interval between the frequent startup and shutdown of the compressor at the temperature reached is small in actual use is that the difference between the shutdown temperature at the temperature reached and the startup temperature reached in the control logic is small, and the heat insulation condition of the maintenance structure of the room or the building where the air conditioner is located is also important. When the air conditioner has strong capability of rapid refrigeration and heating, but the heat preservation and heat insulation performance of a room maintenance structure where the air conditioner is located is poor, the interval of reaching the temperature shutdown is obviously shortened, and therefore the air conditioner is started and stopped too frequently.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following describes a control method, a control device and an air conditioner of the air conditioner provided by the invention with reference to fig. 1.
Referring to fig. 1, a control method of an air conditioner, the control method comprising the steps of:
s1, after an air conditioner receives a starting and mode instruction sent by a remote control, voice or intelligent terminal and the like, acquiring a temperature value ts set by a user, a compressor running time t0 before the first temperature reaching shutdown, a first temperature reaching shutdown time interval delta t1, a first temperature returning starting running time interval delta t1 ', a second temperature reaching shutdown time interval delta t2, a second temperature returning starting running time interval delta t2 ', a third temperature reaching shutdown time interval delta t3 and a third temperature returning starting running time interval delta t3 ';
s2, calculating an average value delta ta of the time intervals of three times of temperature reaching and stopping according to the time interval delta t1 of the first time of temperature reaching and stopping, the time interval delta t2 of the second time of temperature reaching and stopping and the time interval delta t3 of the third time of temperature reaching and stopping;
calculating an average value delta t 'a of the interval of the third-time temperature-returning startup operation time according to the interval delta t 1' of the first-time temperature-returning startup operation time, the interval delta t2 'of the second-time temperature-returning startup operation time and the interval delta t 3' of the third-time temperature-returning startup operation time;
s3, judging the size relation between the average value delta ta of the time interval between the three times of reaching the temperature and stopping the machine and the minimum preset time interval delta tamin for stopping the machine, and judging the size relation between the average value delta t 'a of the time interval between the three times of returning the temperature and starting the machine and the minimum preset time interval delta t' amin for returning the temperature and starting the machine to run;
and S4, executing a temperature accurate control mode according to the judgment result.
Specifically, the minimum preset time interval Δ tamin for the shutdown of the compressor and the minimum preset time interval Δ t' amin for the operation of the compressor after the compressor is started up again are both preset time intervals based on long-time operation data of the compressor. The preset time can be obtained based on the compressor operation data by pre-storing the minimum preset time interval delta tamin for the compressor to stop and the minimum preset time interval delta t' amin for the compressor to return to the temperature and start to operate.
Further, the temperature precision control mode includes: if the average value delta ta of the three-time temperature-reaching shutdown time interval is more than or equal to the minimum preset time interval delta tamin for compressor shutdown and the average value delta T 'a of the three-time temperature-returning startup operation time interval is more than or equal to the minimum preset time interval delta T' amin for compressor temperature-returning startup operation, the capacity requirement and temperature-reaching shutdown control scheme in the air conditioner are reserved, and the temperature-reaching shutdown and temperature-returning startup conditions of the air conditioner compressor are judged according to the compensation difference value mapping relation interval of the temperature ts and the return air temperature T1 set by a user;
and if any condition that the average value delta ta of the three times of temperature reaching shutdown time intervals is less than the minimum preset time interval delta tamin for compressor shutdown or the average value delta t 'a of the three times of temperature returning startup operation time intervals is less than the minimum preset time interval delta t' amin for compressor temperature returning startup operation is met, judging whether fault protection occurs during the startup operation to the continuous three times of temperature reaching shutdown and temperature returning startup operation.
Specifically, the minimum preset time interval Δ tamin for the compressor shutdown is set to 3 min.
Specifically, the minimum preset time interval delta t' amin of the compressor when the compressor is started up after the temperature is returned is set to be 5 min.
Further, the method also comprises the following steps: the judging whether fault protection occurs during the period from starting operation to three continuous times of reaching the temperature shutdown and the temperature returning starting operation comprises the following steps: if the air conditioner is not shut down due to fault protection, the matching of the room building maintenance structure where the air conditioner is located and the original temperature-reaching shut down control scheme of the air conditioner is judged to be low, the compressor is started and stopped too frequently, and capacity requirements and temperature-reaching shut down control are adopted. The comfort is kept by adopting the capacity requirement and the temperature-reaching shutdown control, so that the long-term reliability of the air conditioner is prevented from being reduced due to the fact that the compressor is started and stopped too frequently;
if a positive correction value delta f is added to the reference value of the shutdown interval which can be zero, namely the shutdown interval is not suitable for achieving the shutdown, the compressor operates at a lower frequency in the interval, the inner fan is changed into a middle-low gear, and the throttle valve reduces the opening.
Further, the temperature precision control mode further includes: and if the average value delta ta of the three-time temperature-reaching shutdown time intervals is less than the minimum preset time interval delta tamin for compressor shutdown and the average value delta t 'a of the three-time temperature-returning startup running time intervals is less than the minimum preset time interval delta t' amin for compressor temperature-returning startup running, and no protective shutdown occurs in the continuous three-time temperature-reaching shutdown process, adding a correction value delta f to the reference value required by the temperature-reaching shutdown, cancelling the temperature-reaching shutdown, and adding the correction value delta f to the reference value of the temperature-reaching shutdown interval.
Specifically, the compensation difference between the user set temperature ts and the return air temperature T1 is larger when the user set temperature ts is higher, and the compensation difference between the user set temperature ts and the return air temperature T1 is larger. It can be understood that: the user-set temperature ts is set to four sections, which are [16,22 ], [22, 26 ], [26, 28 ], [28, 30], respectively, and the compensation values of the return air temperature T1 and the user-set temperature ts in the four sections are +2 ℃, 0 ℃,2 ℃ and 4 ℃, respectively. The set temperature ts of the user is high, the compensation value of the return air temperature T1 and the set temperature ts of the user is large, the set temperature ts of the user is low, the compensation value of the return air temperature T1 and the set temperature ts of the user is small, the temperature of the temperature-reaching shutdown and the temperature-returning startup are not lower than 3 ℃ for two lower set temperature intervals, and the temperature of the temperature-reaching shutdown and the temperature-returning startup is not higher than 2 ℃ in two higher set temperature areas.
In the embodiment, referring to fig. 2, taking the user-set temperature ts as 28 ℃ as an example, the control scheme belongs to the interval [28, 30], the capacity requirement and the reaching shutdown control scheme, and the air return temperature T1-the user-set temperature ts compensation value on the right side shown in fig. 2 is controlled according to +4, for example, the room initial temperature is 30 ℃, when the air conditioner is started and operated for a period of time, the air return temperature T1 is reduced to 24 ℃, the room is stopped at the temperature, the throttle valve is opened to the standby opening after returning to zero, the indoor fan continues to supply air, when the indoor air return temperature is increased to more than 26 ℃, the compressor is restarted and operated again, then the compressor is operated according to the requirement, when the air return temperature T1 is lower than 24 ℃, the compressor is stopped at the temperature for the second time, when the air return temperature T1 is increased to more than 26 ℃ again, the compressor is started at the second time, the compressor is started at the temperature for the third time, and is started at the third time, and if the calculated average value Δ T ' a of the reaching the temperature and stopping time is the third time, and the average value Δ T ' a of the third time is the third time of reaching the third time T ' a And if the average value delta ta of the three times of temperature reaching shutdown time intervals is larger than or equal to the minimum preset time interval delta tamin for compressor shutdown, and the average value delta t 'a of the three times of temperature returning startup operation time intervals is larger than or equal to the minimum preset time interval delta t' amin for compressor temperature returning startup operation, the operation is controlled according to the corresponding interval [28, 30] in the graph 2.
If the temperature ts set by the user is 21 ℃, the temperature ts belongs to the interval [16, 22), the capacity requirement and the reaching shutdown control are controlled by referring to the air return temperature T1 on the left side shown in fig. 2-the compensation value of the temperature ts set by the user is-2, for example, the initial temperature of a room is 30 ℃, when the air conditioner is started to operate for a period of time, the air return temperature T1 is reduced to be below 23 ℃, the reaching shutdown is achieved, the indoor fan continues to supply air, when the air return temperature T1 is increased back to be above 26 ℃, the compressor is restarted to operate, then the compressor is operated according to the requirement, when the air return temperature T1 is lower than 23 ℃, the second reaching shutdown is achieved, when the air return temperature T1 is increased back to be above 26 ℃, the compressor is started for the second time, the reaching shutdown and the returning startup are continued for three times, if the average value of the time interval Delta ta of the reaching shutdown and the average value Delta T' a of the time interval of the three times of the returning startup, meanwhile, the condition that the average value delta ta of the three times of temperature reaching shutdown time intervals is larger than or equal to the minimum preset time interval delta tamin for compressor shutdown and the average value delta t 'a of the three times of temperature returning startup operation time intervals is larger than or equal to the minimum preset time interval delta t' amin for compressor temperature returning startup operation is met, the room temperature is maintained between 23 ℃ and 26 ℃ according to the corresponding control operation of the [16, 22) intervals, and the condition that a user forgets to adjust the set temperature in time to enter sleep and the like, so that the room temperature is too low to bring health risks is avoided, and the energy-saving effect is achieved. The compensation value of the high setting temperature zone is positive, the value is large, the compensation value of the low setting temperature zone is small and can be negative, no matter which setting temperature zone is selected by a user, the lower temperature of a room can be closer to the setting temperature of the user, but the actual temperature of the room can not be seriously deviated from the energy-saving comfortable temperature recommended by the nation by 26 ℃ for a long time, even if the user is greedy, or the user psychology that the temperature of the room is reduced quickly due to the fact that the setting temperature is set to be lower when the user starts the machine, the temperature after the temperature of the room is reduced is too low, and the health is prevented from being influenced by sleeping or forgetting to adjust the setting temperature in time after the user starts the machine.
If the three-time temperature-reaching shutdown time interval average value delta ta and the three-time temperature-returning startup operation time interval average value delta t 'a obtained through calculation do not simultaneously meet the condition that the three-time temperature-reaching shutdown time interval average value delta ta is not less than 3min and the three-time temperature-returning startup operation time interval average value delta t' a is not less than 5min, it is judged that the building enclosure structure where the room is located fails to be matched with the control scheme of temperature-reaching shutdown, and a positive correction value is added to a capacity demand f interval, so that the capacity f interval can be the same as or close to the capacity e interval, so that temperature-reaching shutdown is cancelled, the compressor operates at a lower frequency, the rotating speed of the inner fan is reduced from high wind to medium and low wind, and the opening of the throttle valve is reduced while the superheat degree of the indoor evaporator is guaranteed. If the indoor return air temperature rises to or above the interval e, the compressor foundation can be normally controlled, the rotating speed of the fan is recovered to be high wind, and the throttle valve is also recovered to be controlled to be opened according to the conventional superheat degree, exhaust temperature, pressure and the like. Therefore, the long-term reliability of the compressor and the air conditioner system is reduced due to the fact that the compressor is started and stopped too frequently is avoided, the problem that the indoor environment temperature is fluctuated too much due to the fact that the compressor is started and stopped frequently is avoided, and the comfortable indoor environment can be maintained.
In another aspect, there is provided a control apparatus of an air conditioner, the control apparatus applying the control method as described above, including:
an obtaining module, configured to obtain a temperature value ts set by a user, a compressor running time t0 before a first warm-up shutdown, a first warm-up shutdown time interval Δ t1, a first warm-up startup running time interval Δ t1 ', a second warm-up shutdown time interval Δ t2, a second warm-up startup running time interval Δ t2 ', a third warm-up shutdown time interval Δ t3, and a third warm-up startup running time interval Δ t3 ';
