Detailed Description
So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.
When the air conditioner is applied, when the temperature of the air return inlet reaches the preset temperature, the operation parameters of the air conditioner setting device can be improved, the heat exchange strength is increased, and under the condition that the temperature of the air return inlet after heat exchange is increased and the preset temperature is slightly changed, the shutdown control of the indoor unit is carried out, the coverage range of the air conditioning effect can be increased due to the increase of the heat exchange, if the change between the temperature of the air return inlet and the preset temperature is not large, the phenomenon of uneven distribution of airflow organization in the air-conditioning action area is not obvious, the temperature distribution is relatively even, which shows that the temperature in the action area basically reaches the preset temperature, therefore, the air conditioner can be stopped, the probability that the air conditioner is stopped because the actual temperature of an action area does not reach the set temperature and the temperature of the air return inlet reaches the set temperature is reduced, the accuracy of the stop of the air conditioner is improved, and the intelligence of the air conditioner is further improved.
Fig. 1 is a schematic flow chart of an air conditioner shutdown control method in an embodiment of the present disclosure. As shown in fig. 1, the process of the air conditioner stop control may include:
step 101: and acquiring the current return air inlet temperature of the air conditioner.
In the embodiment of the disclosure, the air conditioner can acquire the temperature of the return air inlet in real time or at regular time, and the acquired temperature is the current temperature of the return air inlet each time. The acquisition can be performed by corresponding temperature sensors.
Step 102: and under the condition that the absolute value of the difference value between the current return air inlet temperature and the preset temperature is smaller than a first set value, increasing the operation parameters of the set device of the air conditioner from the first operation parameters to second operation parameters.
In the related art, when the current return air inlet temperature reaches the preset temperature, shutdown control can be performed, and generally, in order to improve the fault tolerance of the air conditioner, if the difference value between the current return air inlet temperature and the preset temperature is within a certain range, it can be determined that the current return air inlet temperature reaches the preset temperature. The difference between the current return air temperature and the preset temperature may be a positive value, or a negative value, such as: when the air conditioner operates in a cooling mode, the difference between the current return air temperature and the preset temperature is a positive value, and when the air conditioner operates in a heating mode, the difference between the current return air temperature and the preset temperature is a negative value. The first set value may be 0.3, 0.5, 0.8, 1, etc., which may be determined according to performance parameters of the air conditioner and the operation mode.
In the embodiment of the disclosure, when the temperature of the current return air inlet reaches the preset temperature, the machine is not stopped immediately, and whether the machine is stopped or not is determined according to the temperature of the return air after the heat exchange degree is increased. Therefore, the absolute value of the difference between the current return air inlet temperature and the preset temperature is smaller than the first set value, that is, when the current return air inlet temperature reaches the preset temperature, the operation parameter of the air conditioner setting device needs to be increased from the first operation parameter to the second operation parameter. The setting means may include: one, two or more of a fan, a compressor, an expansion valve, etc., and thus, the first operating parameter may include: at least one of a first wind speed, a first frequency, a first valve opening, etc., so that the wind speed of the fan can be increased from the first wind speed to a second wind speed, or the operating frequency of the compressor can be increased from the first frequency to a second frequency, or both the wind speed can be increased from the first wind speed to the second wind speed and the operating frequency of the compressor can be increased from the first frequency to the second frequency. Alternatively, the opening degree of the expansion valve is adjusted, which is not specifically listed.
The first wind speed is the current wind speed of the corresponding fan when the current return air inlet temperature reaches the preset temperature, and a preset lifting wind speed amplitude can be extracted, so that the sum of the current wind speed and the lifting wind speed amplitude is the second wind speed. Similarly, the first frequency is the current frequency of the corresponding compressor when the current return air inlet temperature reaches the preset temperature, and a lifting frequency amplitude can be preset, so that the sum of the lifting frequency amplitudes of the current frequency is the second frequency.
Step 103: and controlling the air conditioner indoor unit to stop running under the condition that the setting device runs with the second running parameter and the absolute value of the difference is less than or equal to the second set value.
The size of the air conditioning service area, the type of house, the installation location of the air conditioner, etc., may affect the airflow within the service area and, thus, the temperature at various locations within the service area.
The operation parameters of the setting device of the air conditioner are improved, the setting device operates with the second operation parameter, the coverage range of the heat exchange function of the air conditioner can be immediately increased, if the air conditioner is installed at a proper position, the area size is proper, etc., so that, if not only the temperature of the air conditioner in a close range reaches a preset temperature, if the temperature in the far range reaches the preset temperature, the temperature of the air return inlet collected again is not changed or is changed slightly, if the air flow organization in the air conditioning action area is not uniform, the temperature of the air return inlet which is collected at the beginning reaches the preset temperature, however, the temperature of other positions in the action area may not reach the preset temperature, so that after the heat exchange is increased, the temperature of the air return inlet collected again may be greatly changed, and at this time, the air conditioner can not be stopped, and the air conditioner is required to operate normally in the functions of refrigeration, heating, dehumidification and the like.
Therefore, the air conditioner can be controlled to stop running only under the condition that the temperature change in the action area is not large after the heat exchange is increased, namely, the air conditioner indoor unit is controlled to stop running under the condition that the setting device runs by the second running parameter and the absolute value of the difference is smaller than or equal to the second set value. The temperature in the active region does not vary much with increasing heat exchange, and therefore the second set point is not too great and can generally be only greater than or equal to the first set point, e.g., the second set point can be 1, 1.2, 1.5, etc. For example: the fan operates at a second wind speed, namely the wind outlet force is increased, the acting area of the air conditioner is enlarged, if the temperature difference of each position in the coverage area is increased is not large, the collected temperature of the return air inlet is not changed or changes slightly, namely the absolute value of the difference between the current temperature of the return air inlet and the preset temperature is smaller than or equal to a second set value, and therefore the indoor unit of the air conditioner can be controlled to stop operating.
It can be seen that, in this embodiment, after the return air inlet temperature of air conditioner reached preset temperature, can promote the operating parameter of air conditioner settlement device, increase heat transfer intensity, and under the little condition of change between the return air inlet temperature after the increase heat transfer and preset temperature, carry out indoor set shutdown control, increase the coverage that the heat transfer can increase the air conditioner effect, if the change between return air inlet temperature and the preset temperature is little, it is unobvious to confirm that the air current tissue distributes the inhomogeneous phenomenon in the air conditioner effect region, each position temperature distribution has been more even, thereby can shut down, the accuracy of air conditioner shut down has been improved, the intelligence of air conditioner has also been further improved.
Of course, after the heat exchange energy is increased, if the air flow organization in the air conditioning action area is not uniform, the temperature of the return air inlet may change greatly, at this time, the air conditioner cannot be stopped, and the air conditioner needs to operate normally in the cooling, heating or dehumidifying functions. In addition, in order to avoid various discomfort caused by direct blowing, improve user experience and reduce the probability of error shutdown, in some embodiments, the operation parameter of the setting device is reduced from the second operation parameter to the first operation parameter under the condition that the setting device operates with the second operation parameter and the absolute value of the difference is greater than or equal to the third setting value. After the heat exchange is increased, the temperature of the air return inlet may change greatly, so that the third set value may be larger than the second set value. For example: the third set point may be 2, 2.5, 3, 3.5, etc.
Because the air conditioner may collect the temperature of the return air inlet in real time or at regular time, if the collection frequency is high, the time for the air conditioner to enhance heat exchange is short, and the temperature change of the return air inlet may not be detected in time, in some embodiments, the running time of the setting device running with the second running parameter needs to be recorded; comparing the absolute value of the difference with a set value if the operating time is greater than the set time, the set value comprising: at least one of the second set point and the third set point. Namely, after the heat exchange is increased for a period of time, the shutdown control is carried out according to the collected temperature of the air return inlet. And controlling the air conditioner indoor unit to stop running under the conditions that the running time of the setting device running with the second running parameter is longer than the set time and the absolute value of the difference is less than or equal to the second set value. And reducing the operation parameter of the setting device from the second operation parameter to the first operation parameter under the condition that the operation time of the setting device operating with the second operation parameter is longer than the setting time and the absolute value of the difference is larger than or equal to a third setting value.
Of course, in the case where it is determined that the setting device is not operating with the second operating parameter, the recorded operating time is subjected to the zero clearing processing. Thus, the shutdown control can be ensured to be operated for a plurality of times.
Therefore, the accuracy and the intelligence of shutdown control can be further improved by increasing the control of the heat exchange operation time.
The following operational flow is integrated into a specific embodiment to illustrate the air conditioner shutdown control process provided by the embodiment of the present invention.
In one embodiment of the present disclosure, the first set value is 0.5, the second set value is 1.5, and the third set value is 3.
Fig. 2 is a schematic flow chart of an air conditioner shutdown control method in an embodiment of the disclosure. As shown in fig. 2, the process of the air conditioner stop control may include:
step 201: and acquiring the current return air inlet temperature of the air conditioner.
The current return air inlet temperature of the air conditioner can be obtained in real time or in a timing mode.
Step 202: is the absolute value of the difference between the current return air inlet temperature and the preset temperature less than 0.5? If so, go to step 203, otherwise, go to step 204.
Step 203: and increasing the wind speed of the air conditioner fan from the first wind speed to the second wind speed, and returning to the step 201.
Step 204: determine whether the wind speed of the wind turbine is the second wind speed? If yes, go to step 205, otherwise, go back to step 201.
The wind speed is the second wind speed, and the heat exchange is increased, so that the shutdown control can be continuously performed according to the temperature of the return air inlet. If the heat exchange is not increased, the current function of the air conditioner is executed.
Step 205: is the absolute value of the difference between the current return air inlet temperature and the preset temperature less than or equal to 1.5? If so, go to step 206, otherwise, go to step 207.
Step 206: and controlling the air-conditioning indoor unit to stop running, and returning to the step 201.
Step 207: is the absolute value of the difference between the current return air inlet temperature and the preset temperature greater than or equal to 3? If yes, go to step 208, otherwise, go back to step 201.
Step 208: and reducing the wind speed of the fan from the second wind speed to the first wind speed, and returning to the step 201.
It can be seen that, in this embodiment, after the return air inlet temperature of the air conditioner reaches the preset temperature, the air speed of the air conditioner fan can be increased, the heat exchange strength is increased, the coverage area of the air conditioning effect is increased, under the condition that the return air inlet temperature after heat exchange is increased and the preset temperature is slightly changed, the shutdown control of the indoor unit is performed, if the change between the return air inlet temperature and the preset temperature is not large, the phenomenon that the distribution of airflow tissues in the air conditioning effect area is not uniform can be determined, the temperature distribution of each position is relatively uniform, the shutdown can be performed, the shutdown accuracy of the air conditioner is improved, and the intelligence of the air conditioner is further improved.
In one embodiment of the present disclosure, the first set value is 0.8, the second set value is 1.2, and the third set value is 2.5, and the set time is 1 minute.
Fig. 3 is a flowchart illustrating an air conditioner shutdown control method according to an embodiment of the disclosure. As shown in fig. 3, the process of the air conditioner stop control may include:

Step 303: and controlling the wind speed of the air conditioner fan to operate at a second wind speed, and the frequency of the compressor to operate at a second frequency, and recording the operation time that the wind speed operates at the second wind speed and the compressor operates at the second frequency. Returning to step 301.
The first wind speed is the current wind speed of the corresponding fan when the current return air inlet temperature reaches the preset temperature, and the second wind speed is the sum of the first wind speed and the preset lifting wind speed amplitude. The first frequency is the current frequency of the corresponding compressor when the current return air inlet temperature reaches the preset temperature, and the second frequency is the sum of the first frequency and the preset lifting frequency amplitude. And recording the running time, namely timing and updating the running time.
Step 304: is it determined whether the wind speed of the fan is operating at the second wind speed and the compressor is operating at the second frequency for an operating time greater than 1 minute? If yes, go to step 305, otherwise, go back to step 301.
Judging 305: is the absolute value of the difference between the current return air inlet temperature and the preset temperature less than or equal to 1.2? If so, go to step 305, otherwise, go to step 307.
Step 306: and controlling the air-conditioning indoor unit to stop running, clearing the recorded running time, and returning to the step 301.
Step 307: is the absolute value of the difference between the current return air inlet temperature and the preset temperature greater than or equal to 2.5? If yes, go to step 308, otherwise, go back to step 301.
Step 308: and controlling the wind speed of the fan to operate at a first wind speed, operating the frequency of the compressor at a first frequency, resetting the recorded operation time, and returning to the step 301.
It can be seen that, in this embodiment, after the return air inlet temperature of the air conditioner reaches the preset temperature, the operating parameters of the air conditioner fan and the compressor can be improved, the heat exchange strength is increased, and under the condition that the return air inlet temperature after heat exchange is increased and the preset temperature has small change, the indoor unit shutdown control is performed, the coverage range of the air conditioner action can be increased by increasing the heat exchange, if the change between the return air inlet temperature and the preset temperature is not large, the phenomenon that the airflow organization distribution in the air conditioner action area is not uniform can be determined to be unobvious, the temperature distribution is relatively uniform, the temperature of each position in the action area basically reaches the preset temperature, so that the air conditioner can be shut down, the shutdown accuracy of the air conditioner is improved, and the intelligence of the air conditioner is further. And, still can further improve accuracy and the intellectuality of shutdown control through the control of increaseing the heat transfer time of operation.
According to the air conditioner stop control process, an air conditioner stop control device can be constructed.
Fig. 4 is a schematic structural diagram of an air conditioner shutdown control device according to an embodiment of the present disclosure. As shown in fig. 4, the air conditioner stop control device includes: an acquisition module 410, a lift module 420, and a shutdown module 430.

The lifting module 420 is configured to raise the set device operating parameter of the air conditioner from the first operating parameter to the second operating parameter when the absolute value of the difference between the current return air inlet temperature and the preset temperature is smaller than the first set value.
And the shutdown module 430 is configured to control the air conditioner indoor unit to stop running under the condition that the setting device runs at the second running parameter and the absolute value of the difference is less than or equal to the second set value.
