Specifically, under the condition that the normal running fan works at the wind gear within the rated wind gear range to ensure the normal running of the air conditioner, the normal running fan is controlled to work at the wind gear within the rated wind gear range; properly increasing the wind gear of the normally operating fan under the condition that the normal operation of the air conditioner cannot be ensured when the normally operating fan works at the wind gear within the range of the rated wind gear, and the normal operation of the air conditioner can be ensured by improving the wind gear of the normally operating fan; under the condition that the normal running fan cannot meet the running requirement of the air conditioner even when the wind level is increased, the running parameters of the air conditioner can be adjusted; and under the condition that the normal running fan improves the wind level and reduces the output of the air conditioner and the running of the air conditioner cannot be met, stopping the air conditioner.

Wherein, the output capacity of the fan of normal operating has been decided to rotational speed and electric current, and then has decided the working effect of air conditioner, and the rotational speed of fan and the scope of electric current have then been decided to the windscreen, for guaranteeing the normal operating of fan, must guarantee that the fan moves at certain windscreen within range.

In any of the above technical solutions, preferably, the processor is further configured to execute the computer program to implement: pushing fault information; the fault information includes: operating parameters of the fan and system operating parameters.

In the technical scheme, when the processor is further used for executing a computer program, fault information can also be pushed, wherein the fault information includes, but is not limited to, an operating parameter of the wind turbine and a system operating parameter. By pushing the system operation parameters, a user or maintenance personnel can accurately and timely judge the fan fault and guarantee timely maintenance; the current running state of the fan in normal running can be obtained by pushing the running parameters of the fan, the sustainable running time of the air conditioner in the current state can be obtained under the condition that the fan runs at the over-speed, and then a user or maintenance personnel is prompted to maintain the fan within the sustainable running time. Specifically, the fault information may be displayed on a display device of the air conditioner (such as a digital tube, a remote controller, a line controller, etc.) in a fault code or information manner, and may also be directly or indirectly pushed to a terminal (such as a mobile phone, an upper computer, etc.).

Further, before pushing the fault information, the fault condition may be analyzed, and different fault information may be matched for different fault conditions, including but not limited to the following fault information: the current air conditioner can still maintain normal output and can maintain enough long waiting maintenance time; the current air conditioner can still maintain normal output, but can only maintain the normal output for a short time; the current air conditioner can not maintain normal output, needs to reduce the output capacity, but can maintain enough long time for waiting for maintenance; the current air conditioner cannot maintain normal output, needs to reduce output capacity, and can only maintain the normal output for a short time.

In any of the above technical solutions, preferably, the processor is configured to implement: based on the condition that the current operating condition is the ambient temperature and the operating mode is the refrigeration mode, the method comprises the following steps of adjusting the operating parameters of the system according to the current operating condition, the rated wind gear range of the fan and the current operating parameters: according to the current operation condition, the rated wind gear range and the current operation parameters of the fan, five emergency modes are correspondingly set, and the method specifically comprises the following steps: the first mode is that on the basis that the ambient temperature is lower than a first temperature threshold value and the current wind gear is within a rated wind gear range, the wind gear of the fan is increased, and the air conditioner is controlled to normally operate; the second mode is that on the basis that the ambient temperature is higher than a second temperature threshold value, the wind level of the fan is increased under the condition that the current wind level exceeds the rated wind level range, and the air conditioner is controlled to normally operate; the third mode is that on the basis that the ambient temperature is higher than the second temperature threshold value, the wind level of the fan is increased under the condition that the current wind level is in the rated wind level range, and the output capacity of the air conditioner is controlled to be reduced; the fourth mode is that on the basis that the ambient temperature is higher than the second temperature threshold value, the wind level of the fan is increased under the condition that the current wind level exceeds the rated wind level range, and the output capacity of the air conditioner is controlled to be reduced; and in the fifth mode, the air conditioner is controlled to stop under the condition that the current wind gear exceeds the rated wind gear range and the four modes fail on the basis that the ambient temperature is higher than the second temperature threshold. Wherein the second temperature threshold is greater than the first temperature threshold.

In the technical scheme, under the condition that the current operation condition is the environment temperature and the air conditioner is in the refrigeration mode, five emergency modes are adopted to realize the accurate control of the air conditioner according to the environment temperature, the rated wind gear range of the fan and the current operation parameters of the fan, so that different control modes are provided for different fault conditions, and the flexible and accurate control of the air conditioner is realized. Specifically, the five emergency modes are as follows:

in the first mode, the current temperature environment is low (namely the ambient temperature is lower than a first temperature threshold value), and the fan which normally operates is in a rated wind gear range. At the moment, the wind gear of the fan which normally operates is increased within the range of the rated wind gear, and the normal operation of the air conditioner can be met. Therefore, the wind gear of the fan in normal operation is properly increased, so that the fan in normal operation can operate at a higher wind gear, and the normal operation of the air conditioner is ensured. The emergency mode can be maintained for a long time, the temperature cannot be increased in a large range, and the influence on the comfort level of a user is small.

In the second mode, the current temperature environment is high (namely the ambient temperature is higher than a second temperature threshold), and the fan which normally runs exceeds the rated wind gear range. At the moment, the wind level of the fan in normal operation is increased, and the normal operation of the air conditioner can be met in a short time. Therefore, the wind gear of the fan in normal operation is increased, so that the fan in normal operation operates at an ultrahigh wind gear, and the normal operation of the air conditioner is ensured. The emergency mode can be maintained for a short time, the temperature cannot be increased in a large range in a short time, and the influence on the comfort level of a user is small.

And in the third mode, the current temperature environment is high (namely the ambient temperature is higher than the second temperature threshold), and the fan which normally runs exceeds the rated wind gear range. At the moment, even if the wind level of the fan in normal operation is increased, the normal operation of the air conditioner cannot be met. Therefore, the wind level of the fan in normal operation is properly adjusted to be high, so that the fan in normal operation is operated at a higher wind level, and the output capacity of the air conditioner is reduced (the output capacity of the air conditioner can be reduced by increasing the minimum refrigeration temperature, reducing the frequency of the compressor and the like). The emergency mode can be maintained for a long time, which causes the temperature to rise, and has a great influence on the comfort of the user.

And in the fourth mode, the current temperature environment is high (namely the ambient temperature is higher than the second temperature threshold), and the fan which normally runs exceeds the rated wind gear range. At the moment, even if the wind level of the fan in normal operation is increased, the normal operation of the air conditioner cannot be met. Therefore, the normal operation fan is shifted up so that the normal operation fan is operated at an ultra-high wind, and the output capacity of the air conditioner is reduced, for example, by increasing the minimum cooling temperature and decreasing the compressor frequency to reduce the output capacity. The emergency mode can be maintained for a short time, which causes the temperature to rise, and has a great influence on the comfort of the user.

In the fifth mode, the current temperature environment is higher (namely the environment temperature is higher than the second temperature threshold), and the ultra-high wind gear can not ensure the output control of the unit according to the normal capacity, and can not ensure the capacity reduction output control, such as increasing the minimum refrigeration temperature and reducing the frequency of the compressor. And at the moment, the fault of the fan is directly reported, the emergency mode is invalid, and the unit is forbidden to operate. This situation may occur, but is not limited to, a situation where all fans are damaged.

It should be noted that the first temperature threshold and the second temperature threshold may be set according to actual conditions, but it is required to ensure that the second temperature threshold is greater than the first temperature threshold.

In any of the above technical solutions, preferably, the priority order of the emergency mode according to the reliability setting is, from high to low: a first mode, a third mode, a second mode, a fourth mode and a fifth mode; the priority order of setting the emergency mode according to the comfort is as follows in sequence from high to low: the first mode, the second mode, the third mode, the fourth mode and the fifth mode.

In the technical scheme, the user can set the priority of the emergency mode according to self definition or system default. Specifically, when the priority order of the emergency mode is set according to reliability, the order from high to low is: the first mode, the third mode, the second mode, the fourth mode and the fifth mode. When the priority order of the emergency modes is set according to the comfort, the first mode, the second mode, the third mode, the fourth mode and the fifth mode are sequentially arranged from high to low.

It is worth noting that in the emergency mode described above, the wind gear of the fan normally operating in each emergency mode determines the reliability of the emergency mode: the fan which runs normally in a rated wind gear range is most reliable, the fan which runs normally in a higher wind gear is the second time, and the fan which runs normally in an ultrahigh wind gear is the lowest in reliability, so that the first mode and the third mode are obviously superior to other modes in reliability. The length of time each emergency mode is maintained and the output capacity of the air conditioner determine the comfort of the emergency mode, so that the first mode and the second mode are obviously superior to the other modes in terms of comfort.

A second aspect of the present invention provides an operation control method of an air conditioner. The air conditioner comprises a fan, and the operation control method comprises the following steps: acquiring system operation parameters of the air conditioner and the number of fans with faults; and adjusting the operating parameters of the normally operating fans according to the operating parameters and the number of the systems.

The operation control method provided by the invention is applied to the air conditioner, and in the using process of the air conditioner, partial failure or total failure of the fan is possible, and the working effect of the air conditioner can be directly influenced when the fan fails. The operation control method provided by the invention can acquire the system operation parameters of the air conditioner and the number of the fans with faults, and the processor adjusts the operation parameters of the fans which normally operate according to the actual conditions after acquiring the system operation parameters and the number of the fans with faults.

In this technical solution, the current operating condition of the air conditioner may be obtained, and the current operating condition of the air conditioner includes but is not limited to: the current ambient temperature, the target ambient temperature set by the user. After the current operating condition of the air conditioner is obtained, the processor adjusts the operating parameters of the system according to the current operating condition of the air conditioner, the rated wind gear range of the fan and the current operating parameters of the fan, and the air conditioner continuously works on the premise of ensuring the operation safety of the air conditioner.

Specifically, under the condition that the normal operation of the fan can be ensured to operate normally by working at the wind gear within the rated wind gear range, the fan is controlled to operate at the wind gear within the rated wind gear range; under the condition that the normal operation of the air conditioner cannot be ensured when the fan works at the wind level within the rated wind level range, and the normal operation of the air conditioner can be ensured by improving the wind level of the fan in normal operation, the wind level of the fan in normal operation is properly increased; under the condition that the normal operation of the air conditioner cannot be met even when the wind level of the fan in normal operation is increased, the operation parameters of the air conditioner can be adjusted; and under the condition that the normal running fan improves the wind level and reduces the output of the air conditioner and the running of the air conditioner cannot be met, stopping the air conditioner.

In any of the above technical solutions, preferably, the method further includes: pushing fault information; the fault information includes: operating parameters of the fan and system operating parameters.

In the technical scheme, when partial fans are detected to have faults, fault information can be pushed, wherein the fault information includes but is not limited to the operating parameters of the fans and the operating parameters of the system. By pushing the system operation parameters, a user or maintenance personnel can accurately and timely judge the fan fault and guarantee timely maintenance; the current running state of the fan in normal running can be obtained by pushing the running parameters of the fan, the sustainable running time of the air conditioner in the current state can be obtained under the condition that the fan runs at the over-speed, and then a user or maintenance personnel is prompted to maintain the fan within the sustainable running time. Specifically, the fault information may be displayed on a display device of the air conditioner (such as a digital tube, a remote controller, a line controller, etc.) in a fault code or information manner, and may also be directly or indirectly pushed to a terminal (such as a mobile phone, an upper computer, etc.).

In any of the above technical solutions, preferably, the step of adjusting the system operation parameters according to the current operation condition, the rated windshield range of the fan, and the current operation parameters under the condition that the current operation condition is the ambient temperature and the operation mode is the cooling mode specifically includes: according to the current operation condition, the rated wind gear range and the current operation parameters of the fan, five emergency modes are correspondingly set, and the method specifically comprises the following steps: the first mode is that on the basis that the ambient temperature is lower than a first temperature threshold value and the current wind gear is within a rated wind gear range, the wind gear of the fan is increased, and the air conditioner is controlled to normally operate; the second mode is that on the basis that the ambient temperature is higher than a second temperature threshold value, the wind level of the fan is increased under the condition that the current wind level exceeds the rated wind level range, and the air conditioner is controlled to normally operate; the third mode is that on the basis that the ambient temperature is higher than the second temperature threshold value, the wind level of the fan is increased under the condition that the current wind level is in the rated wind level range, and the output capacity of the air conditioner is controlled to be reduced; the fourth mode is that on the basis that the ambient temperature is higher than the second temperature threshold value, the wind level of the fan is increased under the condition that the current wind level exceeds the rated wind level range, and the output capacity of the air conditioner is controlled to be reduced; and in the fifth mode, the air conditioner is controlled to stop under the condition that the current wind gear exceeds the rated wind gear range and the four modes fail on the basis that the ambient temperature is higher than the second temperature threshold. Wherein the second temperature threshold is greater than the first temperature threshold.

And in the fourth mode, the current temperature environment is high (namely the ambient temperature is higher than the second temperature threshold), and the fan which normally runs exceeds the rated wind gear range. At the moment, even if the wind level of the fan in normal operation is increased, the normal operation of the air conditioner cannot be met. Therefore, the normal operation fan is shifted up in wind so that the normal operation fan operates at an ultra-high wind, and the output capacity of the air conditioner is reduced, for example, by increasing the minimum cooling temperature, and reducing the compressor frequency to reduce the output energy). The emergency mode can be maintained for a short time, which causes the temperature to rise, and has a great influence on the comfort of the user.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

An operation control system of an air conditioner, an operation control method of an air conditioner, and a computer-readable storage medium according to some embodiments of the present invention are described below with reference to fig. 1 to 5.

In the embodiment, in the use process of the air conditioner, the possibility of partial failure or total failure of the fan exists, and the failure of the fan can directly influence the working effect of the air conditioner. In the operation control system 1 of the air conditioner according to this embodiment, the controller executes the computer program to obtain the system operation parameters of the air conditioner and the number of the fans having faults, and after obtaining the system operation parameters and the number of the fans having faults, the processor 20 adjusts the operation parameters of the fans that normally operate according to actual conditions.

By adjusting the operating parameters of the normally operating fan, on one hand, the complete machine halt of the air conditioner can be avoided, and the continuous and stable operation of the air conditioner is ensured; on the other hand, the running parameters of the fan which runs normally can be matched with the system running parameters of the air conditioner, the safe running of the air conditioner is ensured, and the use requirement is met. Specifically, the processor 20 determines whether the number of fans in normal operation can ensure continuous operation of the air conditioner according to the system operation parameters of the air conditioner and the number of fans having faults, and ensures that the comfort of the user is in the best state or the reliability of the whole unit is ensured on the premise of ensuring the safe operation of the air conditioner, so as to realize the longest operation time.

The second embodiment is as follows:

an operation control system 1 of an air conditioner according to a second embodiment of the present invention is an operation control system 1 of an air conditioner including a blower, the operation control system 1 including: a memory 10 for storing a computer program; a processor 20 for executing a computer program to implement: acquiring system operation parameters of the air conditioner and the number of fans with faults; adjusting the operating parameters of the normally operating fans according to the operating parameters and the number of the systems; acquiring the current operating condition of the air conditioner; and adjusting system operation parameters according to the current operation conditions, the rated wind gear range of the fan and the current operation parameters.

In this embodiment, the processor 20 may obtain the current operating condition of the air conditioner, and adjust the operating parameters of the system according to the current operating condition of the air conditioner, the rated wind range of the fan, and the current operating parameters of the fan, in addition to obtaining the operating parameters of the system and the number of fans having faults, and adjusting the operating parameters of the normal operating fan according to the actual conditions. The air conditioner can continuously work on the premise of ensuring the operation safety of the air conditioner.

Specifically, under the condition that the normal running fan works at the wind gear within the rated wind gear range to ensure the normal running of the air conditioner, the normal running fan is controlled to work at the wind gear within the rated wind gear range; properly increasing the wind gear of the normally operating fan under the condition that the normal operation of the air conditioner cannot be ensured when the normally operating fan works at the wind gear within the range of the rated wind gear, and the normal operation of the air conditioner can be ensured by improving the wind gear of the normally operating fan; under the condition that the normal running fan cannot meet the running requirement of the air conditioner even when the wind level is increased, the normal running parameters of the air conditioner can be adjusted; and stopping the air conditioner under the condition that the normal running fan improves the wind level and reduces the output of the air conditioner and the running of the air conditioner cannot be met.

Preferably, the system operating parameters include at least one of: system operating mode, discharge temperature of the compressor, pressure of the compressor, operating frequency of the compressor, temperature of the heat exchanger. The system operation mode can be a cooling mode, a heating mode or a dehumidification mode; the exhaust temperature of the compressor, the pressure of the compressor and the working frequency of the compressor determine the working efficiency of the air conditioner, the parameters are closely related to the operating parameters of the fan in normal operation, and the operating parameters of the fan in normal operation are adjusted to directly influence the exhaust temperature of the compressor, the pressure of the compressor, the working frequency of the compressor and the temperature of the heat exchanger, so that the working efficiency of the air conditioner is influenced.

Preferably, the operating parameters of the wind turbine include at least one of: speed, current, gear. Wherein, the output capacity of the fan of normal operating has been decided to rotational speed and electric current, and then has decided the working effect of air conditioner, and the rotational speed of fan and the scope of electric current have then been decided to the windscreen, for guaranteeing the normal operating of fan, must guarantee that the fan moves at certain windscreen within range.

The third concrete embodiment:

an operation control system 1 of an air conditioner according to a third embodiment of the present invention is an operation control system 1 of an air conditioner including a blower, the operation control system 1 including: a memory 10 for storing a computer program; a processor 20 for executing a computer program to implement: acquiring system operation parameters of the air conditioner and the number of fans with faults; adjusting the operating parameters of the normally operating fans according to the operating parameters and the number of the systems; acquiring the current operating condition of the air conditioner; adjusting system operation parameters according to the current operation conditions, the rated wind gear range of the fan and the current operation parameters; pushing fault information; the fault information includes: operating parameters of the fan and system operating parameters.

In this embodiment, when the processor 20 is used to execute a computer program, fault information may also be pushed, wherein the fault information includes, but is not limited to, operational parameters of the wind turbine and system operational parameters. By pushing the system operation parameters, a user or maintenance personnel can accurately and timely judge the fan fault and guarantee timely maintenance; the current running state of the fan in normal running can be obtained by pushing the running parameters of the fan, the sustainable running time of the air conditioner in the current state can be obtained under the condition that the fan runs at the over-speed, and then a user or maintenance personnel is prompted to maintain the fan within the sustainable running time. Specifically, the fault information may be displayed on a display device of the air conditioner (such as a digital tube, a remote controller, a line controller, etc.) in a fault code or information manner, and may also be directly or indirectly pushed to a terminal (such as a mobile phone, an upper computer, etc.).

Further, taking the current operating condition as the ambient temperature and the operating mode as the cooling mode as an example, the following five emergency modes are correspondingly set according to the current operating condition, the rated wind gear range of the fan and the current operating parameters:

And in the fourth mode, the current temperature environment is high (namely the ambient temperature is higher than the second temperature threshold), and the fan which normally runs exceeds the rated wind gear range. At the moment, even if the wind level of the fan in normal operation is increased, the normal operation of the air conditioner cannot be met. Therefore, the wind level of the fan in normal operation is increased, so that the fan in normal operation operates at an ultra-high wind level, and the output capacity of the air conditioner is reduced. The emergency mode can be maintained for a short time, which causes the temperature to rise, and has a great influence on the comfort of the user.

It should be noted that the first temperature threshold and the second temperature threshold may be set according to actual conditions, but it is required to ensure that the second temperature threshold is greater than the first temperature threshold. Specifically, the first temperature threshold and the second temperature threshold are correspondingly set according to the operation mode and the target operation temperature. For example, in the cooling mode, the target cooling temperature is 20 ℃, the first temperature threshold value is 25 ℃, and the second temperature threshold value is 30 ℃.

Setting the priority order of the emergency modes according to the reliability, wherein the five modes are as follows from high to low: a first mode, a third mode, a second mode, a fourth mode and a fifth mode; the priority order of the emergency modes is set according to the comfort, and the five modes are sequentially from high to low: the first mode, the second mode, the third mode, the fourth mode and the fifth mode. The user can select according to actual needs.

Further, before pushing the fault information, the fault condition may be analyzed, and different fault information may be matched for different fault conditions, specifically as follows:

when the air conditioner is in the first mode, the method can push that the current air conditioner enters an emergency operation state due to the fault of a few fans, but the air conditioner can still maintain normal output and can maintain enough long maintenance waiting time; when the air conditioner is in the second mode, the method can push that the current air conditioner enters an emergency operation state due to the fact that a few fans have faults, but the air conditioner can still maintain normal output, but only can maintain a short time; when the air conditioner is in the third mode, the method can push that the current air conditioner enters an emergency operation state due to the fact that a few fans have faults, the air conditioner cannot maintain normal output, the output capacity needs to be reduced, and the enough maintenance waiting time can be maintained; when the air conditioner is in the fourth mode, the situation that the current air conditioner enters an emergency operation state due to the fact that few fans have faults, the air conditioner cannot maintain normal output, the output capacity needs to be reduced, and the air conditioner can only be maintained for a short time can be pushed; when the air conditioner is in the fifth mode, the situation that the current air conditioner enters an emergency operation state due to the fact that a few fans have faults, the air conditioner cannot maintain normal output and needs to be shut down for processing can be pushed.

s102, acquiring system operation parameters of the air conditioner and the number of fans with faults;

and S104, adjusting the operating parameters of the normally operating fans according to the operating parameters and the number of the systems.

The operation control method provided by the invention is applied to an air conditioner, and more particularly, to an air conditioner with a plurality of fans. In the use process of the air conditioner, the possibility of partial failure or total failure of the fan exists, and the working effect of the air conditioner can be directly influenced when the fan fails. The operation control method provided by the invention can acquire the system operation parameters of the air conditioner and the number of the fans with faults, and the processor adjusts the operation parameters of the fans which normally operate according to the actual conditions after acquiring the system operation parameters and the number of the fans with faults.

By adjusting the operating parameters of the normally operating fan, on one hand, the complete machine halt of the air conditioner can be avoided, and the continuous and stable operation of the air conditioner is ensured; on the other hand, the running parameters of the fan which runs normally can be matched with the system running parameters of the air conditioner, the safe running of the air conditioner is ensured, and the use requirement is met. Specifically, the processor judges whether the number of fans in normal operation can ensure continuous operation of the air conditioner according to system operation parameters of the air conditioner and the number of fans with faults, and ensures that the comfort of a user is in the best state or the reliability of the whole unit is ensured on the premise of ensuring the safe operation of the air conditioner, so that the longest operation time is realized.

The air conditioner can continuously work on the premise of ensuring the operation safety of the air conditioner.

Specifically, under the condition that the normal operation of the fan can be ensured to operate normally by working at the wind gear within the rated wind gear range, the fan is controlled to operate at the wind gear within the rated wind gear range; under the condition that the normal operation of the air conditioner cannot be ensured when the fan works at the wind level within the rated wind level range, and the normal operation of the air conditioner can be ensured by improving the wind level of the fan in normal operation, the wind level of the fan in normal operation is properly increased; under the condition that the normal operation of the air conditioner cannot be met even when the wind level of the fan in normal operation is increased, the operation parameters of the air conditioner can be adjusted; and stopping the air conditioner under the condition that the normal running fan improves the wind level and reduces the output of the air conditioner and the running of the air conditioner cannot be met.

s306, acquiring the current operating condition of the air conditioner;

and S310, pushing the fault information.

In this embodiment, when it is detected that a part of the fans are in failure, failure information may also be pushed, where the failure information includes, but is not limited to, operating parameters of the fans and system operating parameters. By pushing the system operation parameters, a user or maintenance personnel can accurately and timely judge the fan fault and guarantee timely maintenance; the current running state of the fan in normal running can be obtained by pushing the running parameters of the fan, the sustainable running time of the air conditioner in the current state can be obtained under the condition that the fan runs at the over-speed, and then a user or maintenance personnel is prompted to maintain the fan within the sustainable running time. Specifically, the fault information may be displayed on a display device of the air conditioner (such as a digital tube, a remote controller, a line controller, etc.) in a fault code or information manner, and may also be directly or indirectly pushed to a terminal (such as a mobile phone, an upper computer, etc.).

Furthermore, under the condition that the current operation condition is the environment temperature and the air conditioner is in the refrigeration mode, five emergency modes are adopted to realize the accurate control of the air conditioner according to the environment temperature, the rated wind gear range of the fan and the current operation parameters of the fan, so that different control modes are provided for different fault conditions, and the flexible and accurate control of the air conditioner is realized. Specifically, the five emergency modes are as follows:

Further, the priority order of the emergency modes is set according to the reliability, and the five modes are as follows in sequence from high to low: a first mode, a third mode, a second mode, a fourth mode and a fifth mode; the priority order of the emergency modes is set according to the comfort, and the five modes are sequentially from high to low: the first mode, the second mode, the third mode, the fourth mode and the fifth mode. The user can select according to actual needs.

Specifically, the operation of the air conditioner according to the present invention will be explained with reference to fig. 5. Notably, in this embodiment, the processor includes: the fan fault detection module, the fault judgment and analysis module, the fault pushing module and the emergency processing module are used as examples for explanation. However, it will be understood by those skilled in the art that the above-mentioned functional modules are modular and separate processing of the operation control system of the first aspect of the present invention, and do not depart from the main idea of the present invention. Specifically, the method comprises the following steps: the function of the functional module is as follows:

fan fault detection module: the fault detection module is used for detecting whether the fan breaks down, if the deviation between the actual rotating speed of the fan and the preset rotating speed is large, the deviation between the actual current of the fan and the preset current is large and the like, the fan is judged to break down, and fault information is handed to the fault judgment analysis module for processing.

A fault judgment and analysis module: and after the number of fans with current faults is obtained, analyzing and judging according to a certain rule, and giving a complete machine operation strategy under the current faults to the emergency processing module.

An emergency processing module: and receiving the information of the fault judgment and analysis module and controlling the air conditioner to operate in an emergency.

A fault pushing module: and receiving the information of the fault judgment and analysis module and pushing fault information.

Wherein, the failure pushing module may be but not limited to: receiving fault information obtained by the fault judging and analyzing module (or directly obtaining the fault information from the fault detecting module), and presenting the fault information to a user or a maintenance worker in a fault information mode; such fault information may include, but is not limited to: the fault code or information is displayed on a display device (such as a digital tube, a remote controller, a line controller and the like) of the air conditioner in a fault code or information mode, or the fault code or information is directly or indirectly pushed to a terminal (such as a mobile phone, an upper computer and the like).

Taking the air conditioner in the cooling mode as an example, five emergency modes are defined according to the ambient temperature, the rated wind range of the fan and the current operating parameters of the fan. In the refrigeration mode, the fan mainly has a condensation effect on the outdoor heat exchanger, and the lower the ambient temperature, the lower the required wind level. The five emergency modes are as follows:

The selection of the above five modes can be performed according to, but not limited to, user-defined or system default priorities, such as:

wherein, on the premise of the reliability of the air conditioner and ensuring that the emergency mode maintaining time is long enough: first mode > third mode > second mode > fourth mode > fifth mode; the user comfort is the highest priority: first mode > second mode > third mode > fourth mode > fifth mode.

Further, the failure pushing information will also push different failure information according to the current failure analysis and processing strategy. As for the first mode, the push information may be: the current air conditioner enters an emergency operation state due to the fault of a few fans, but the air conditioner can still maintain normal output and can maintain enough waiting time for maintenance.

The invention provides an operation mode aiming at the failure of the fan, ensures that the air conditioner can continue to operate, simultaneously prompts the failure, strives for necessary time for maintenance and reduces the influence on the use of a user.

According to the invention, when the fan of the air conditioner breaks down, the current condition is more intelligently judged and analyzed to carry out corresponding processing, so that the influence on the comfort of a user is reduced, and meanwhile, enough time is provided for maintenance.
