Related definitions of other terms will be given in the description below.
Referring to fig. 1, fig. 1 is a schematic flow chart of an anti-freezing control method of an air conditioner according to an embodiment of the application, as shown in fig. 1, the anti-freezing control method of an air conditioner includes steps S101 to S104.
And step S101, acquiring indoor temperature, and acquiring the motor rotating speed of the indoor unit of the air conditioner when the indoor temperature is determined to meet a first condition.
When the air conditioner is started for refrigeration, frosting and freezing can occur due to self reasons or external factors, so that the actual running state of the air conditioner can be monitored in the using process of the air conditioner, the frostproofing treatment of the air conditioner is realized, and the healthy running of the air conditioner is further ensured.
In an embodiment, when performing anti-freezing control adjustment of an air conditioner, an indoor temperature of an indoor environment in which the air conditioner is located is obtained to perform corresponding judgment processing according to the collected indoor temperature, specifically, whether a first condition of anti-freezing adjustment is met is determined according to the collected indoor temperature, and when the first condition is determined to be met, a motor rotation speed of an indoor unit of the air conditioner is obtained, wherein the first condition is that the indoor temperature meets a set first temperature threshold, and the first temperature threshold is a temperature at which frost is most likely to occur in the indoor unit of the air conditioner, and the first temperature threshold can be obtained based on a plurality of experiments, and specific data is set according to actual conditions.
In practical application, in the operation process of air conditioner, when the air conditioner is in lower temperature operation, can be because the influence of refrigeration demand and environment for the condition that the air conditioner appears freezing, and the appearance that freezes the condition can lead to the condition that the air conditioner appears inefficiency in the operation in-process, if in time protect simultaneously, can make the frost probably spread on the connecting pipe, and then influence to life etc. of air conditioner, consequently need the timely effectual control air conditioner to prevent frostbite protection.
In the refrigerating process, the first temperature threshold value is a temperature value obtained based on experiments or other experiences, and frost is most likely to occur in the air conditioner, so that the indoor temperature is reasonably avoided to be at the temperature or is kept at the temperature for a long time in the using process, and the indoor temperature is collected by using the set temperature sensor to determine whether the air conditioner is likely to be controlled to prevent freezing.
For example, if the set first temperature threshold is K and the collected indoor temperature is Tc, when Tc is greater than K, it is determined that the air conditioner will not freeze at this time, i.e. will not frost, so that it is not necessary to control the air conditioner to perform anti-freezing protection, but periodic temperature collection and determination are performed according to the set temperature sampling period, for example, once every 10 minutes.
And when Tc is less than or equal to K, judging that the air conditioner is likely to be frozen at the moment, and further acquiring related data for judging in order to judge more accurately. Specifically, the motor rotation speed of the air conditioner indoor unit is acquired at this time, so that further judgment is made according to the obtained motor rotation speed.
And step S102, collecting the air outlet temperature of the air outlet of the air conditioner and the air inlet speed of the air inlet when the rotating speed of the motor is smaller than or equal to a rotating speed threshold value.
When it is determined that the collected indoor temperature is low, that is, less than the set first temperature threshold, further judgment needs to be made to determine whether or not to control the air conditioner to perform anti-freezing protection, and how to perform anti-freezing operation when the anti-freezing protection is required. Specifically, when the collected indoor temperature is determined to be smaller than or equal to the set rotating speed threshold value when the collected indoor temperature meets the first condition, the air outlet temperature of the air outlet and the air inlet speed of the air inlet of the air conditioner are collected and obtained through the set sensor, and further subsequent judgment is carried out according to the obtained air outlet temperature and the obtained air inlet speed.
In an embodiment, the rotation speed threshold is a motor rotation speed of an indoor unit used when the air conditioning system is most prone to frosting, which can be obtained specifically according to practical experiments, and the situation that freezing is likely to occur at the moment is determined when the obtained motor rotation speed is determined to be smaller than or equal to the rotation speed threshold, and the situation is achieved through collection and judgment of the air outlet temperature of the air outlet and the air inlet speed of the air inlet when further judgment is performed.
In addition, when the obtained motor rotation speed is greater than the set rotation speed threshold value, the condition that the air conditioner is not frozen at the moment is determined, so that the running state of the air conditioner is kept unchanged when an air conditioner adjusting instruction input by a user is not received at the moment, and detection and judgment are performed again after the air conditioner is operated for a certain time.
Referring to fig. 2, fig. 2 is a flow chart illustrating steps of obtaining an air outlet temperature and an air inlet speed according to an embodiment of the present application. Wherein, the step includes step S201 to step S203.
Step S201, when the rotating speed of the motor is less than or equal to a rotating speed threshold value, collecting the air outlet temperature of an air outlet of the air conditioner, and comparing the air outlet temperature with a second temperature threshold value;
step S202, if the air outlet temperature is less than or equal to the second temperature threshold value, collecting the air inlet speed of the air conditioner air inlet;
step S203, if the outlet air temperature is greater than the second temperature threshold, executing the steps of: and collecting the air outlet temperature of the air outlet of the air conditioner, and comparing the air outlet temperature with a second temperature threshold value.
In the detection and judgment process, each data acquisition can be used for determining whether the air conditioner needs to be protected against freezing, and meanwhile, the data of each parameter data is acquired under certain conditions, for example, the subsequent data acquisition and judgment can be performed only when the previous data meets the set conditions. Specifically, when the obtained motor rotation speed is determined to be less than or equal to a rotation speed threshold value, acquiring the air outlet temperature of the air conditioner air outlet through a set temperature sensor, comparing the air outlet temperature with a second temperature threshold value, further acquiring the air inlet speed of the air conditioner air inlet by using the set air speed sensor when the air outlet temperature is less than or equal to the second temperature threshold value, and executing the steps when the air outlet temperature is greater than the second temperature threshold value: and collecting the air outlet temperature of the air outlet of the air conditioner.
In practice, the second temperature threshold is combined with the configuration of each air conditioning system, and when the freezing test is passed and the air conditioning system starts to frost the nth pipe, the outlet air temperature at that time is set as a threshold value, and after the threshold value is obtained, the outlet air temperature is stored in the air conditioning system in advance.
For example, when the intake air temperature is less than or equal to the set second temperature threshold value, since there is a high possibility that freezing and frosting occur, it is necessary to determine which reason the freezing and frosting occur, and at this time, the intake air speed of the air conditioner intake will be obtained to further determine whether or not there is a freezing and frosting condition and for what reason.
In addition, when the air inlet temperature is greater than the set second temperature threshold value, the situation that the air conditioner is frozen and frosted at present is judged, but the indoor temperature is lower, namely the indoor temperature is smaller than the set first temperature threshold value, so that the running state of the air conditioner is kept unchanged at the moment, and the air outlet temperature of the air outlet of the air conditioner is detected again after a certain time to judge. The time interval for re-detection can be preset, for example, 10 minutes is a detection period, so that when an external adjusting instruction for the air conditioner is not received, the running state of the air conditioner is periodically monitored, and further, corresponding adjustment is timely performed when freezing and frosting are possible to occur, so that the situation of freezing and frosting is avoided.
And step 103, determining whether an anti-freezing condition is met according to the air outlet temperature and the air inlet speed.
In an embodiment, after the air outlet temperature of the air outlet of the air conditioner and the air inlet speed of the air inlet of the air conditioner are obtained according to the running state of the air conditioner, whether the obtained air outlet temperature and the air inlet speed meet the freezing prevention condition is determined, that is, whether freezing prevention protection is needed at the moment is determined, when the corresponding freezing prevention condition is determined to be met, the air outlet speed of the air outlet of the air conditioner is obtained, and then a corresponding control and regulation instruction is generated according to the obtained related data.
In the running process of the air conditioner, the situation of freezing and frosting of the air conditioner can be caused by the actual running condition, such as too low refrigerating temperature, and also can be caused by the abnormal running of the air conditioner, such as dirty blockage, so that when the freezing and frosting prevention is carried out, the situation of freezing and frosting of the air conditioner is required to be accurately determined for what reason, and further when the freezing and frosting caused by the actual running is determined, the air conditioner can be protected and regulated by controlling the running of the air conditioner, and when the frosting caused by the abnormal running of the air conditioner is determined, corresponding prompt and feedback information can be timely sent out to maintain the air conditioner.
Referring to fig. 3, fig. 3 is a flow chart illustrating a step of determining whether an anti-freezing condition is satisfied according to an embodiment of the present application. Wherein, the step includes steps S301 to S303.
Step 301, when the air outlet temperature is less than or equal to the second temperature threshold value, comparing the air inlet speed with a first air speed threshold value to determine whether an anti-freezing condition is met according to a comparison result;
step S302, if the wind inlet speed is larger than the first wind speed threshold value, determining that an anti-freezing condition is met;
and step S303, if the air inlet speed is smaller than or equal to the first air speed threshold value, determining whether the air conditioner is in an abnormal operation state, and determining that an anti-freezing condition is met when the air conditioner is not in the abnormal operation state.
In an embodiment, when the judgment and the determination are performed, the obtained wind speed of the wind inlet is compared with a preset first wind speed threshold value, so that whether the anti-freezing condition is met or not is determined according to the obtained comparison result. Specifically, if the air inlet wind speed is determined to be greater than a first wind speed threshold value, determining that an anti-freezing condition is met, then obtaining the air outlet wind speed of an air outlet of the air conditioner to perform anti-freezing protection on the air conditioner, and when the air inlet wind speed is determined to be less than or equal to the first wind speed threshold value, firstly determining whether the air conditioner is in an abnormal operation state, and further determining that the anti-freezing condition is met when the air conditioner is not in the abnormal operation state.
In the actual running process of the air conditioner, if the air conditioner is not timely maintained and other treatments are not carried out, abnormal conditions such as dirt blocking can occur to the air conditioner, and when the air conditioner runs under the conditions, the use efficiency of the air conditioner is lower, and more energy consumption losses can exist. Therefore, when the air conditioner is controlled and adjusted, besides timely adjusting the running state of the air conditioner, the air conditioner needs to be adjusted, for example, the situation that the air conditioner is frozen and frosted due to dirt blockage or component damage is determined, at the moment, the air outlet wind speed, the air inlet wind speed, the position of the air deflector and the like cannot be reasonably adjusted, and then the air conditioner needs to be maintained and treated to ensure that the air conditioner is not abnormal.
The first wind speed threshold is used for determining whether the air conditioner is operating normally, for example, the first wind speed threshold can be set to be used for determining whether the filter screen of the air inlet of the air conditioner is congested, and other determination can be made. When the filter screen of the air inlet of the air conditioner is determined to be jammed, the anti-freezing protection can be realized by lifting the motor rotation speed of the indoor unit or adjusting the position of the air deflector if the jam condition is small, if the jam condition is serious, the air conditioner can be judged to be in an abnormal operation state, and the anti-freezing protection can not be necessarily realized when the adjustment is carried out, so that the anti-freezing protection can be realized by maintaining the air conditioner.
In one embodiment, in determining whether the air conditioner is in an abnormal operation state, the method includes: when the air inlet speed is smaller than or equal to the first air speed threshold value, collecting the wind field pressure of an air outlet of the air conditioner, and determining whether the air conditioner is in an abnormal operation state according to the air outlet pressure; if the wind field pressure is determined to be positive, determining that the air conditioner is not in the abnormal operation state; and if the wind field pressure is determined to be negative, determining that the air conditioner is in the abnormal operation state.
As can be seen from the above description, when the intake wind speed is less than or equal to the set first wind speed threshold value, it is indicated that the air conditioner may be in an abnormal operation state at this time, so that an abnormal determination needs to be made, and when the abnormal determination is made, the determination is made by acquiring the wind field pressure at the air outlet of the air conditioner, specifically, if the obtained wind field pressure is a positive value, it is determined that the air conditioner is normally operated at this time, and when the obtained wind field pressure is a negative value, it is indicated that the air conditioner is in an abnormal operation state at this time.
In practice, when the pressure of the wind field is positive, the current dirty blocking condition of the air inlet can also ensure the normal operation of the sample machine, the return air phenomenon of the air outlet can not be formed, the water hanging phenomenon of the fan can not be caused, and the water blowing phenomenon of the air duct can not be caused, so that the normal operation of the air conditioner is judged when the pressure of the wind field is positive. A further determination is made at this point to determine how to adjust the air conditioner.
And step S104, when the anti-freezing condition is determined to be met, acquiring the air outlet wind speed of the air outlet of the air conditioner, and generating an anti-freezing instruction based on the air inlet wind speed and the air outlet wind speed so as to control the air conditioner to respond to the anti-freezing instruction.
When it is determined that the air conditioner satisfies the freezing prevention condition, it is then necessary to determine how to adjust the air conditioner. Specifically, when the condition of preventing freezing is determined to be met, the air outlet air speed of the air outlet of the air conditioner is obtained, and then a corresponding anti-freezing instruction is generated according to the obtained air inlet air speed and the air outlet air speed so as to control the air conditioner to respond to the generated anti-freezing instruction, wherein the anti-freezing instruction comprises an adjusting instruction of the air conditioner, and the anti-freezing protection of the air conditioner is realized by controlling the air conditioner to respond to and control information contained in the instruction anti-freezing instruction.
