Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, based on the examples herein, which are within the scope of the application as defined by the claims, will be within the scope of the application as defined by the claims.
Fig. 1 is a flowchart of an air conditioner control method according to an embodiment of the present application, as shown in fig. 1, including:
s11: acquiring frosting influence parameters;
s12: when the frosting influence parameters meet the conditions close to frosting, adjusting the operation parameters of the air conditioner;
s13: when the air conditioner frosts, the air conditioner is controlled to run at a corresponding temperature point according to the frosting influence parameters so as to defrost the air conditioner.
The defrosting control logic of the conventional air conditioner is rough, as shown in fig. 2, when the temperature of an evaporator tube of an outdoor unit is detected to be T Outer tube ≤-t1 ℃ during heating of the air conditioner, defrosting is carried out under certain conditions such as T Outer ring temperature, electric heating is stopped, the compressor stops running, the four-way valve is commutated (powered off) to be adjusted to a refrigerating mode, the inner fan stops, the outer fan stops, the compressor is started, the frequency of the compressor is slowly increased to the frequency of defrosting, and the defrosting method is to defrost through fixed defrosting time and defrosting period. If defrosting is performed according to a fixed period, for example, after the temperature of the outdoor tube is lower than-3 ℃, the air conditioner continues to operate for 40 minutes, defrosting is performed, if defrosting is not finished, the temperature of the outdoor tube is lower than-3 ℃, so that the air conditioner continues to operate for 40 minutes, and defrosting is performed again. And sequentially and circularly proceeding. And when the temperature T Outer tube ≥t2 ℃ meets the conditions of T Outer ring temperature and the like, the air conditioner exits defrosting, the compressor is stopped, the external fan is started at the same time, the four-way valve is switched to a heating mode (electrified), the internal fan carries out cold air prevention logic stop operation or different rotation speed control according to the temperature of the evaporator of the indoor unit, and the frequency of the compressor is slowly increased to the frequency of the user-set temperature to continue heating operation. In the traditional defrosting process, although the inner fan is stopped, the indoor unit heat exchanger does not continuously provide heating requirements for users, meanwhile, the indoor unit heat exchanger is equivalent to a refrigerating mode without the inner fan, and the relatively cold indoor unit heat exchanger still provides cold air for indoor environments through natural convection of air, heat conduction of the air and the indoor unit heat exchanger and a heat radiation mode, so that users who want to heat feel poor in comfort; meanwhile, after defrosting is finished, the air conditioning system needs to be modulated into a heating mode from a refrigerating mode for a period of time, then the temperature is slowly increased to the required temperature of a user, the process time is long, and the comfort of the user is poor.
Therefore, the defrosting logic of the traditional air conditioner controls the specific defrosting process only by fixing the defrosting time, the fixed defrosting time and the control time of the defrosting period are determined under the design working condition of the air conditioner, and the actual use working condition of a user is different from the design working condition, so that the problems of overlong defrosting time, overlong defrosting period, unclean defrosting and the like exist.
In addition, when the refrigerating air conditioner is in a special operation condition, frosting of the heat exchanger of the indoor unit occurs, as shown in fig. 3, during the evening, when the outdoor environment temperature is 24 ℃, and the indoor environment temperature is 27 ℃, the user starts refrigerating, and the temperature of air flowing through the heat exchanger of the outdoor unit is lower than that of air flowing through the heat exchanger of the indoor unit. At this time, the heat exchanger of the indoor unit has a larger wet load, and the heat exchanger of the outdoor unit can start condensing the refrigerant at the initial section, so that the heat exchanger has higher condensing efficiency, thereby storing a certain amount of refrigerant, leading more refrigerant to be retained in the condenser of the outdoor unit, and leading the evaporator of the indoor unit to be in a slightly liquid-deficient state. Before the unit cools the room, the condenser of the outdoor unit contains more refrigerant, so that the evaporator of the indoor unit operates under the state of being lower than the freezing point, the heat exchanger of the indoor unit is frozen, and the conventional air conditioner lacks preventive measures for the conditions.
In this embodiment, the air conditioner control method includes acquiring frost formation influence parameters; controlling the air conditioner to run at a corresponding temperature point according to the frosting influence parameters; and when the frosting influence parameter meets the condition close to frosting, adjusting the operation parameter of the air conditioner, and adjusting the operation parameter of the air conditioner to prolong the defrosting time of the air conditioner, so as to prevent frosting of the air conditioner, and controlling the air conditioner to operate at a corresponding temperature point according to the frosting influence parameter, so that the problem of long defrosting time of the air conditioner caused by unsuitable operation temperature can be avoided, and further, the defrosting time and the defrosting period of the air conditioner are reduced.
Fig. 4 is a flowchart of an air conditioner control method according to another embodiment of the present application, as shown in fig. 4, the air conditioner control method includes:
s41: acquiring the indoor environment temperature, the outdoor environment temperature, the time required by the indoor room temperature for every preset degree celsius change and the temperature variation corresponding to the preset frequency of every variable frequency lifting;
S42: when the product of the time required by changing the indoor room temperature by the preset degree centigrade and the temperature change quantity corresponding to the preset frequency of each frequency conversion rise and fall is smaller than a preset threshold value, adjusting the operation parameters of the air conditioner;
In this embodiment, whether the defrosting start condition is close or not is determined, and if the defrosting start condition is close, the air conditioner is prevented from frosting by adjusting the compressor frequency and the fan rotation speed control.
In some embodiments, adjusting the air conditioner operating parameters when the frost affecting parameters meet the near frost condition includes:
The fan speed of the air conditioner was adjusted according to the outdoor ambient temperature and the outdoor unit pipe temperature as shown in table 1.
Table 1 outdoor environmental temperature and outdoor machine tube temperature and fan rotation speed comparison table
As shown in table 1, when the relationship of the temperature change amount (relationship of a1= Δt/0.2 and a2= Δf/0.1) of 0.1Hz per frequency-change elevation for the length of time required for every 0.2 degrees celsius change in the indoor room temperature satisfies the approaching frosting condition, the indoor unit is determined to drop several wind steps according to the size of T Outer ring 、T Outer tube .
It should be noted that, the denominator values in a1= Δt/0.2 and a2= Δf/0.1 are used to locate 0.2 and 0.1, the example uses 1 degree fahrenheit as the variation, the accurate control temperature is taken as an example, and the actual temperature control difference may be 0.3, 0.4, 0.5, 0.6, and other differences. In this example, the latest 0.1Hz variable frequency air conditioner is taken as an example, and other variable frequency differences of 0.05Hz, 0.1, 0.2, 0.3 and the like can be adopted. This example is illustrated only with 0.2 and 0.1, and is not limiting.
In some embodiments, further comprising: and adjusting the rotating speed of a fan of the air conditioner according to the temperature difference between the tube temperature of the outdoor unit and the preset frosting temperature.
The method comprises the steps of adjusting the quantity of air gear downshifts of an indoor unit by controlling the speed of approaching the frosting temperature of an outdoor unit pipe temperature sensing bulb, and if the difference value between the outdoor unit temperature sensing bulb temperature and the variation quantity (a1= [ delta ] T/0.2) of the preset frosting temperature is relatively large, rapidly reducing a plurality of air gears by the indoor unit to prevent the frosting of an air conditioner; if the difference between the temperature of the temperature sensing bulb of the outdoor unit and the variation (a1= delta T/0.2) of the preset frosting temperature is smaller, the indoor unit can quickly drop by 1 wind gear to prevent the frosting of the air conditioner.
The embodiment can control the heat exchanger of the outdoor unit of the air conditioner to delay entering the frosting, and the frosting quantity of the heat exchanger is greatly reduced compared with that of the traditional air conditioner even though the heat exchanger enters the frosting, and the frosting time and the frosting period of the heat exchanger are reduced due to the reduction of the frosting quantity, so that the cool air provided by the indoor unit for a room needing heating is less, and the comfort of a user is greatly improved.
In order to delay the occurrence of frosting of the heat exchanger of the indoor unit or avoid the occurrence of repeated frosting and repeated defrosting of the air conditioner under severe working conditions when the refrigeration air conditioner is in a special working condition, the embodiment also provides a method for synchronously controlling the wind shield of the indoor unit, as shown in fig. 5. When the relation (relation of a1= DeltaT/0.2 and a2= DeltaF/0.1) of the temperature change amount of 0.1Hz per frequency conversion rise and fall of the indoor room temperature per 0.2 ℃ satisfies the condition of approaching frosting, the temperature is less than or equal to 27 ℃ with T Outer ring -T Inner ring ＝△T(22℃＜T Outer ring and less than or equal to 8 ℃ with DeltaT being less than or equal to 0 ℃ and the sizes of T inner pipe and T Outer tube determine that the outdoor unit falls by a plurality of wind steps.
The method comprises the steps of controlling the temperature of an outdoor unit pipe temperature sensing bulb to approach the frosting temperature to carry out the quantity of indoor and outdoor wind gear downshifts, and if the change quantity (a1= [ delta ] T/0.2) of the indoor unit environment is smaller, rapidly reducing a plurality of wind gears by the indoor unit to prevent the air conditioner from frosting; if the variation (a1= delta T/0.2) of the temperature sensing bulb of the outdoor unit from the frosting temperature is relatively large, the indoor unit is required to quickly drop by 1 wind gear to prevent the frosting of the air conditioner. The scheme can control the indoor unit heat exchanger of the air conditioner to delay entering frosting, thereby ensuring the normal cooling operation of the air conditioner in a severe environment, when the air conditioner operates for a period of time, the indoor environment temperature is gradually reduced, the air conditioner does not refrigerate in a warm environment, the air conditioner can exit the logic of preventing the indoor unit heat exchanger from frosting, the refrigerating function is normally provided for users, and the comfort of the users is greatly improved.
S43: establishing a second relation table of relation between environment change parameters and air conditioner control temperature points, wherein the environment change parameters comprise at least one of time, geographic position, environment temperature and current season of financial control logic;
S44: and when the air conditioner operates for the first time, controlling the air conditioner to operate at a corresponding temperature point according to the second relation table.
The time, geographic position, temperature, season time and the like of the first entering control logic fed back by the communication module such as the WIFI module automatically identify the relation table of the first entering logic execution. The control logic can be automatically identified when the subsequent air conditioner operates again, and the logic operation is prevented from being selected one by one, so that the temperature adjusting time and energy consumption of the air conditioner are greatly saved, and the comfort of a user is improved.
In some embodiments, further comprising:
and correcting the control temperature point so that the air conditioner operates at the corrected temperature point.
The correction of the control temperature point can be implemented through a machine learning algorithm, as shown in table 2, the temperature point A, B, C, D is tested as training data of machine learning in the air conditioner research and development stage, and then, when the actual air conditioner operates, according to the tested temperature point, the record is automatically carried out, if the logic section is started from C, the logic section is directly started from C next time, instead of identifying A first and then identifying C.
Table 2 machine learning training data table
The machine learning is to select different temperature entry points according to the early temperature change rate, perform logic control, and if entering from C, the C value may have a certain gap from the target value, and the temperature always fluctuates within the range of C+0.1 and C-0.1, so that machine learning is required to correct the value, and then the corrected value is listed in the position of C to replace the value of C. Other values and so on.
The conventional normal air conditioner runs from the first bar of the logic whenever it is. The logic section which is wanted by the user cannot be automatically entered, in the embodiment, the machine learning can automatically identify the logic section and record the logic section, the next time the logic section directly enters the corresponding temperature point for control, and the identification judgment is not repeated.
S45: establishing a first relation table of the relation between the indoor and outdoor environment temperature difference, the time required by changing the indoor room temperature by preset degrees celsius, the temperature change quantity corresponding to the preset frequency of each frequency conversion lifting and the air conditioner control temperature point;
S46: and controlling the air conditioner to operate at the corresponding temperature point according to the first relation table.
Because the defrosting time or the defrosting temperature of the air conditioner is determined under the design working condition, the corresponding air conditioner is not suitable for different geographic areas, different use environments and different seasons. The air conditioner has the conditions of higher energy consumption, repeated frosting and the like in the using process. According to the relation quantity between the temperature change speed a1= delta T/0.2 and the frequency change speed a2= delta F/0.1, the relation between the change rates of the two is tested under different working conditions, and a first relation table is established so as to realize differentiation and self-adaptive control of different air conditioners.
In some embodiments, further comprising: fitting a quadratic equation binomial curve according to the time required by changing the indoor room temperature by preset degrees celsius and the temperature change quantity corresponding to the preset frequency of each frequency conversion rise and fall;
and determining the control temperature point of the air conditioner according to the quadratic equation binomial curve so that the air conditioner operates at the temperature point.
In the embodiment, the air conditioner control can enter a defrosting function, defrosting time and defrosting period control according to different geographic areas, different use environments and different seasons through self-adaptive learning; based on reinforcement learning, fuzzy control of the air conditioner operation temperature point is realized, the time for entering defrosting of the air conditioner is prolonged, the defrosting time of the air conditioner is shortened, and the defrosting period of the air conditioner is shortened.
