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 is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a flowchart of an air conditioner control method according to an embodiment of the present application, and as shown in fig. 1, the air conditioner control method includes:
s11: acquiring frosting influence parameters;
s12: when the frosting influence parameters meet the condition close to frosting, adjusting the operating parameters of the air conditioner;
s13: when the air conditioner frosts, the air conditioner is controlled to operate at the corresponding temperature point according to the frosting influence parameter so as to defrost the air conditioner.
The conventional air conditioner has a relatively rough defrost control logic, as shown in fig. 2, when the air conditioner heats, the temperature of the outdoor unit evaporator tube is detected TOuter tube≤-t1At a certain temperature of TOuter ringThe defrosting method comprises the steps of defrosting when the temperature and other conditions are met, stopping electric heating, stopping running of the compressor, reversing (powering off) the four-way valve to adjust the four-way valve to a refrigeration mode, stopping the inner fan, stopping the outer fan, starting the compressor, and slowly increasing the frequency of the compressor to defrosting frequency to run. If defrosting is carried out according to a fixed period, for example, after the temperature of the outdoor pipe is lower than minus 3 ℃, the air conditioner continues to run for 40 minutes, then defrosting is carried out, if defrosting is not clean, the temperature of the outdoor pipe is still lower than minus 3 ℃, therefore, the air conditioner continues to run for 40 minutes, and then defrosting is carried out again. And the circulation is carried out sequentially. When T isOuter tube≥t2DEG C, satisfies TOuter ringWhen the temperature and other conditions are adjusted, defrosting is stopped, the compressor is stopped, the outer fan is started simultaneously, the four-way valve is reversed (electrified) to be adjusted into a heating mode, and the inner fan evaporates according to the indoor unitThe temperature of the generator is controlled by cold air prevention logic to stop running or different rotating speeds, and the frequency of the compressor is slowly increased to the frequency of the temperature set by a user to continue heating running. Although the inner fan is stopped in the traditional defrosting process, the heat exchanger of the indoor unit does not continuously provide heating requirements for users, meanwhile, the heat exchanger of the indoor unit is equivalent to a refrigeration mode without the inner fan, and the relatively cold heat exchanger of the indoor unit still provides cold air for indoor environment through natural air convection, heat conduction of air and the heat exchanger of the indoor unit and heat radiation modes, so that users who want to heat feel poor comfort; meanwhile, after defrosting is finished, the air conditioning system needs a period of time to be adjusted into a heating mode from a refrigerating mode, then the required temperature of a user is slowly increased in frequency, the process time is long, and the comfort of the user is poor.
Therefore, the defrosting logic of the traditional air conditioner only controls the specific defrosting process 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, the condition that the heat exchanger of the indoor unit frosts can occur when the refrigeration air conditioner is in a special operation condition, as shown in fig. 3, when the outdoor environment temperature is 24 ℃ and the indoor environment temperature is 27 ℃ in the evening, a user starts refrigeration, 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 the moment, the heat exchanger of the indoor unit has a larger wet load, and the heat exchanger of the outdoor unit can begin to condense the refrigerant in the initial section, so that the condensing efficiency is higher, a certain amount of refrigerant can be stored, more refrigerant is retained in the condenser of the outdoor unit, and the evaporator of the indoor unit is in a state of being slightly lack of liquid. Before a unit cools a room, because an outdoor unit condenser contains more refrigerants, an indoor unit evaporator runs under the state below the freezing point, and a heat exchanger of the indoor unit freezes, and the traditional air conditioner lacks preventive measures for the situation.
In the embodiment, the air conditioner control method comprises the steps of obtaining frosting influence parameters; controlling the air conditioner to operate at a corresponding temperature point according to the frosting influence parameter; and when the frosting influence parameter meets the condition close to frosting, adjusting the air conditioner operation parameter, prolonging the defrosting time of the air conditioner by adjusting the air conditioner operation parameter, preventing the air conditioner from frosting, controlling the air conditioner to operate at the corresponding temperature point according to the frosting influence parameter, and avoiding the problem of long defrosting time of the air conditioner caused by improper operation temperature, thereby realizing the reduction of the defrosting time and the defrosting period of the air conditioner.
Fig. 4 is a flowchart of an air conditioning control method according to another embodiment of the present application, and as shown in fig. 4, the air conditioning control method includes:
s41: acquiring indoor environment temperature, outdoor environment temperature, time required by every change of indoor room temperature by preset centigrade and temperature variation corresponding to every variable frequency lifting preset frequency;
s42: when the product of the time required by the indoor room temperature per change of the preset centigrade and the temperature change amount corresponding to the variable frequency lifting preset frequency is less than the preset threshold, adjusting the air conditioner operation parameters;
in the embodiment, the air conditioner is prevented from frosting by judging whether the defrosting starting condition is approached or not and adjusting the frequency of the compressor and the rotating speed of the fan to control if the defrosting starting condition is approached.
In some embodiments, adjusting the air conditioner operating parameter when the frosting impact parameter meets the approaching frosting condition comprises:
the fan speed of the air conditioner was adjusted according to the outdoor ambient temperature and the outdoor unit duct temperature as shown in table 1.
TABLE 1 outdoor ambient temp. and outdoor machine pipe temp. and fan speed comparison table
As shown in table 1, when the relationship between the length of time required for the indoor room temperature to change by 0.2 degrees celsius and the amount of temperature change per frequency conversion rise/fall by 0.1Hz (the amount of relationship between a1=Δt/0.2 and a2=Δf/0.1) satisfies the condition close to frosting, the relationship is determined based on TAn outer ring,TOuter tubeThe size of the air inlet pipe determines the descending of the indoor unit by a plurality of wind gears.
It should be noted that the denominator values in a1=Δt/0.2 and a2=Δf/0.1 are 0.2 and 0.1, and in this example, 1 degree fahrenheit is taken as the variation, the precise control temperature is taken as an example, and the actual temperature control difference may be other differences such as 0.3, 0.4, 0.5, 0.6, and the like. In this example, the latest 0.1Hz variable frequency air conditioner is taken as an example, and other variable frequency differences such as 0.05Hz, 0.1, 0.2, 0.3 and the like can be also adopted. This example is illustrated by 0.2 and 0.1, but 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 pipe temperature of the outdoor unit and the preset frosting temperature.
The method comprises the steps that the number of downshifting of wind gears of an indoor unit is adjusted by controlling the speed at which the temperature of a temperature sensing bag of an outdoor unit approaches to the frosting temperature, and if the difference value between the temperature sensing bag of the outdoor unit and the preset frosting temperature is larger (a 1 =deltaT/0.2), the indoor unit needs to rapidly lower a plurality of wind gears to prevent the air conditioner from frosting; if the difference value between the temperature of the temperature sensing bulb of the outdoor unit and the variation (a 1= [ Delta ] T/0.2) of the preset frosting temperature is smaller, the indoor unit can quickly reduce 1 wind gear to prevent the air conditioner from frosting.
The embodiment can control the heat exchanger of the outdoor unit of the air conditioner to delay entering frosting, the frosting amount of the outdoor unit of the air conditioner is greatly reduced compared with that of the traditional air conditioner even though the outdoor unit of the air conditioner enters frosting, and because the frosting amount is reduced, the defrosting time and the defrosting period of the outdoor unit of the air conditioner are reduced, so that the indoor unit provides less cold air for a room which needs to be heated, and the comfort of a user is greatly improved.
In order to delay the frosting of the heat exchanger of the indoor unit when the refrigeration air conditioner is in a special operation condition or avoid the repeated frosting and repeated defrosting of the air conditioner under a severe condition, the embodiment also provides a method for synchronously controlling the air damper of the indoor unit, which is shown in fig. 5. The time required for every 0.2 degree centigrade change in the indoor room temperature,When the relation of the temperature change amount of 0.1Hz per variable frequency lifting (the relation amount of a1= [ Delta ] T/0.2 and a2= [ Delta ] F/0.1) meets the condition of approaching frosting, the relation of T and T is satisfiedOuter ring-TInner ring＝△T(22℃＜TOuter ringDelta T is less than or equal to 27 ℃ and less than 0 ℃ and less than or equal to 8 ℃), TInner tubeAnd TOuter tubeThe size of the air inlet pipe determines the wind level of the outdoor unit.
The number of downshifting the wind gears inside and outside the room is controlled by controlling the speed of the temperature sensing package of the outdoor unit approaching the frosting temperature, and if the variation (a 1 =deltaT/0.2) of the environment of the indoor unit is smaller, the indoor unit can quickly reduce a plurality of wind gears to prevent the air conditioner from frosting; if the variation (a 1= [ Delta ] T/0.2) of the temperature sensing bulb of the outdoor unit and the frosting temperature is large, the indoor unit rapidly reduces 1 wind gear to prevent the air conditioner from frosting. According to the scheme, the air conditioner indoor unit heat exchanger can be controlled to delay entering frosting, so that the normal refrigeration operation of the air conditioner in a severe environment is guaranteed, after the air conditioner is operated for a period of time, the indoor environment temperature is gradually reduced, the air conditioner is no longer refrigerated in the warm environment, the air conditioner can exit the logic for preventing the frosting of the indoor unit heat exchanger, the refrigeration function is normally provided for users, and the comfort of the users is greatly improved.
S43: establishing a second relation table of the relation between the environment change parameters and the air conditioner control temperature points, wherein the environment change parameters comprise at least one of time, geographical 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 the corresponding temperature point according to the second relation table.
And automatically identifying a relation table executed by the first entering logic through the time, the geographical position, the temperature, the seasonal time and the like of the first entering control logic fed back by the communication module such as the WIFI module. 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 the energy consumption of the air conditioner are greatly saved, and the comfort of a user is improved.
In some embodiments, further comprising:
the control temperature point is corrected so that the air conditioner operates at the corrected temperature point.
The correction of the control temperature point can be realized through a machine learning algorithm, as shown in table 2, the temperature points a, B, C and D are tested in the air conditioner research and development stage to serve as training data for machine learning, then, when the actual air conditioner runs, the temperature points are automatically recorded according to the tested temperature points, if the temperature points enter the logic section from C, the temperature points directly enter from C next time, and the condition that the temperature points are recognized after the temperature points are recognized is avoided.
TABLE 2 machine learning training data sheet
If the temperature enters from C, because the C value may have a certain difference from the target value, the temperature always fluctuates in the ranges of C +0.1 and C-0.1, at this time, machine learning is needed to correct the value, and then the corrected value is listed in the former C position to replace the value of C. Other numbers are analogized.
