Description
Technical Field
The invention relates to the technical field of air conditioning equipment control, in particular to an air conditioning chassis electric heating control method, an air conditioner and a computer readable storage medium.
Background
When the air conditioner is in heating operation, because the outdoor environment temperature is lower, water vapor in the air can form condensate water precipitation on the heat exchanger of the outdoor unit, when the condensate water is lower than 0 ℃, the condensate water can frost on the heat exchanger and gradually freeze and accumulate on the chassis, and the heat exchange capacity of the heat exchanger is reduced and the risk that the fan blade is damaged due to potential icing is caused. In order to solve the problems, an electric heating belt is additionally arranged on the chassis of the existing air conditioner, and the electric heating belt works to heat so as to melt ice cubes on the chassis, quicken the drainage of the chassis, reduce the ice of the chassis and avoid the accumulation of the ice cubes.
The chassis electric heating belt is a resistance wire, when the temperature condition that the electric heating belt is started is met, alternating current is continuously supplied, heating is achieved through the heating mode of the resistance wire, and when the temperature condition that the electric heating belt is closed is met, an alternating current power supply is cut off to stop the electric heating belt.
The existing chassis electric heating belt keeps continuously working in the starting process, the influence caused by alternating voltage is not considered, the electric power energy waste is caused when the high power supply voltage is input, and the chassis electric heating belt is easy to burn out when the existing chassis electric heating belt works under the high power of the high power supply voltage for a long time.
Disclosure of Invention
The first aim of the invention is to provide an air conditioner chassis electric heating control method considering the influence of alternating voltage variation, which reduces energy consumption and avoids burning out an electric heating belt.
A second object of the present invention is to provide an air conditioner capable of implementing the above-described electric heating control method for an air conditioner chassis.
A third object of the present invention is to provide a computer-readable storage medium capable of implementing the above-described air conditioner chassis electric heating control method.
The electric heating control method for the air conditioner chassis provided by the first object of the invention comprises the following steps: when the opening condition of the electric heater is met; generating a voltage coefficient according to power supply alternating voltage data acquired by preset alternating voltage data, and controlling the electric heater to operate in an intermittent mode or a continuous mode according to a preset numerical value interval where the voltage coefficient is located.
According to the scheme, the voltage coefficient reflects the change condition of the power supply alternating current voltage, the operation modes of the electric heater are different according to the difference of preset numerical intervals where the voltage coefficient is located, the electric heater is prevented from continuously operating for a long time, the energy consumption is reduced, and the electric heating belt is prevented from being burnt out.
The method comprises the steps of obtaining power supply alternating voltage data according to preset alternating voltage data, wherein the step of generating a voltage coefficient comprises the step of generating the voltage coefficient according to the ratio of the power supply alternating voltage data to the preset alternating voltage data; in the step of controlling the intermittent operation or continuous operation of the electric heater according to the preset numerical interval where the voltage coefficient is located: if the voltage coefficient is larger than a first preset value, controlling the electric heater to operate in a first intermittent mode; if the voltage coefficient is smaller than a second preset value, controlling the electric heater to run in a continuous mode; the first preset value is larger than 1, and the second preset value is smaller than 1.
From the above, the larger the voltage coefficient is, the higher the current power supply voltage is reflected, and when the voltage coefficient exceeds 1, the current overvoltage is judged, so that the electric heater is controlled to operate in a first intermittent mode; when the voltage coefficient is far smaller than 1, the electric heater is controlled to operate in a continuous mode.
In a further scheme, in the step of controlling the intermittent operation or continuous operation of the electric heater according to a preset numerical interval where the voltage coefficient is located: if the voltage coefficient is between the second preset value and the first preset value, judging whether the electric heater is electrified for the first time; if yes, controlling the electric heater to run in a continuous mode; if not, controlling the electric heater to continuously operate in the primary mode. If the original mode is the intermittent mode, the electric heater is controlled to operate in a second intermittent mode.
From the above, when the voltage coefficient is between the second preset value and the first preset value, the voltage coefficient is near 1, and the control is performed according to the actual condition of the chassis at this time, if the electric heater is not started before, the current ice melting demand is large, so that the continuous mode operation of the electric heater is controlled, and if the electric heater is started before, the current ice melting demand is relatively small, the electric heater can select another relatively fixed intermittent mode operation.
In a further scheme, in the first intermittent mode, the power-on duration of the electric heater is the quotient of the work cycle of the electric heater and the voltage coefficient in the work cycle of the electric heater.
From the above, it can be seen that, when the voltage coefficient exceeds the first higher preset value, in the first intermittent mode, the energizing duration of the electric heater is related to the magnitude of the voltage coefficient, and the larger the voltage coefficient, the more the energizing duration is broken, and the longer the deenergizing duration is. The mode ensures that the heating capacity of the electric heater is ensured as much as possible on the premise that the first intermittent mode can avoid burning.
In another further scheme, in the second intermittent mode, the power-on duration of the electric heater is the product of the work cycle of the electric heater and a second preset value in the work cycle of the electric heater.
From the above, when the power supply ac voltage data is in the interval from the second preset value to the first preset value, the second preset value with the smallest interval is used as the proportional value to calculate the power-on duration in the working period. The mode ensures that the heating capacity of the electric heater is ensured as much as possible on the premise that the second intermittent mode can avoid burning.
The preset alternating voltage data are generated according to the product of rated voltage data and a temperature correction coefficient, and the value of the temperature correction coefficient is determined according to the preset temperature interval where the obtained detection temperature value is located.
As can be seen from the above, the preset ac voltage data for calculating the voltage coefficient should be related to the rated voltage data of the electric appliance. Because the electric heater is a resistance wire, the influence of temperature on resistance and the influence of temperature on voltage are required to be considered, and therefore, the influence of temperature can be eliminated through preset alternating voltage data obtained after the rated voltage data is corrected by the temperature correction coefficient related to the current environment temperature or the chassis temperature.
Still further, the opening condition includes: the detected temperature value is lower than a preset starting temperature value; after the step of controlling the intermittent mode operation or the continuous mode operation of the electric heater according to the preset numerical value interval where the voltage coefficient is located: and stopping the electric heater when the detected temperature value is higher than a preset closing temperature value.
From the above, the detected temperature is the external environment temperature, and the detected temperature value is lower than 0 ℃ to consider the icing phenomenon, so that the electric heater needs to be started for deicing; and stopping deicing when the temperature rises to a certain value.
In a further scheme, when the difference between the detected temperature value and the preset starting temperature value is smaller than a third preset value, the temperature correction coefficient takes a first coefficient value; when the difference between the detected temperature value and the preset starting temperature value is larger than or equal to a third preset value and smaller than 0, the temperature correction coefficient takes a second coefficient value which is smaller than the first coefficient value; when the detected temperature value is larger than or equal to the preset starting temperature value and smaller than the preset intermediate temperature value, the temperature correction coefficient takes a third coefficient value which is smaller than the second coefficient value; when the detected temperature value is larger than or equal to the preset intermediate temperature value and smaller than the preset closing temperature value, the temperature correction coefficient takes a fourth coefficient value which is smaller than the third coefficient value.
From the above, the correction is performed according to the interval of the outer ring temperature, and the rule that the higher the outer ring temperature is, the smaller the temperature correction coefficient value is, and the lower the outer ring temperature is, the larger the temperature correction coefficient value is, and the temperature correction coefficient is also related to the preset starting temperature value and the preset closing temperature value.
The second object of the present invention provides an air conditioner including a processor for implementing the above-mentioned electric heating control method of the air conditioner chassis when executing a computer program stored in a memory.
A third object of the present invention is to provide a computer readable storage medium having a computer program stored thereon, which when executed by a processor implements the above-mentioned air conditioner chassis electric heating control method.

Holding conditions of the electric heater: if T Start-up ≤T Outer ring ≤T Closing And controlling the chassis electric heater to operate in an original state.
When the closing condition T is satisfied Outer ring ＞T Closing And step S11 is executed when the judgment result of the step S2 is NO, the chassis electric heater is turned off or kept in an original off state, and the unit keeps running in a heating mode.
And T is detected when the start-up condition is satisfied for F minutes in succession Outer ring ＜T Start-up If the judgment result of the step S2 is yes, the step S3 is executed to acquire the current power supply alternating current voltage data U of the unit in Preset ac voltage data U Presetting And calculates the power supply alternating voltage data U in And preset alternating voltage data U Presetting As the voltage coefficient K Electric power 。
Wherein, the current power supply alternating voltage data U can be obtained through an alternating voltage sampling circuit in And acquiring preset alternating voltage data Upreset by reading data stored in the chip, U Presetting According to rated voltage data U of air conditioning unit place Rated for And a temperature correction coefficient m: u (U) Presetting ＝m×U Rated for The value of the temperature correction coefficient m is according to the acquired detection temperature value T Outer ring Determining the preset temperature interval, and conforming to T Outer ring The higher the temperature correction coefficient m is, the smaller T is Outer ring The lower the temperature correction coefficient m is, the larger the rule is.
Wherein: when detecting the temperature value T Outer ring And a preset starting temperature value T Start-up Is less thanThird preset value K 3 The temperature correction coefficient m takes a first coefficient value;
when detecting the temperature value T Outer ring And a preset starting temperature value T Start-up The difference of (2) is greater than or equal to a third preset value K 3 When the temperature correction coefficient m is smaller than 0, the temperature correction coefficient m takes a second coefficient value which is smaller than the first coefficient value;
when detecting the temperature value T Outer ring Is greater than or equal to a preset starting temperature value T Start-up And is smaller than a preset intermediate temperature value K 4 When the temperature correction coefficient m is a third coefficient value, the third coefficient value is smaller than the second coefficient value;
when detecting the temperature value T Outer ring Greater than or equal to a preset intermediate temperature value K 4 And when the temperature correction coefficient m is smaller than the preset closing temperature value, the temperature correction coefficient m takes a fourth coefficient value, and the fourth coefficient value is smaller than the third coefficient value.
In this embodiment, a third predetermined value K 3 At-5, preset intermediate temperature value K 4 Is T Closing -1, the value of the temperature correction coefficient m is between 0.8 and 1.2:
when T is Outer ring -T Start-up And 5, taking 1.2 as the temperature correction coefficient m.
When-5 is less than or equal to T Outer ring -T Start-up When the temperature is less than 0, the temperature correction coefficient m is 1.1.
When T is Start-up ≤T Outer ring ＜T Closing At-1, the temperature correction coefficient m takes 1.
When T is Closing -1≤T Outer ring ≤T Closing The temperature correction coefficient m is 0.8.
Acquiring current power supply alternating current voltage data U of unit in Preset ac voltage data U Presetting And calculates the power supply alternating voltage data U in And preset alternating voltage data U Presetting As the voltage coefficient K Electric power Then, step S4 is executed to determine the voltage coefficient K Electric power Whether or not it is greater than a first preset value K 1 Wherein, a first preset value K 1 The first preset value K can be obtained by reading the data stored in the chip 1 Should be greater than 1, in this embodiment, the first presetValue K 1 Taking 1.1.
If the judgment result of the step S4 is yes, the step S5 is executed to control the electric heater to operate in the first intermittent mode.
In the first intermittent mode, the power-on duration T of the electric heater is within the working period X of the electric heater Energizing 1 For the working period X and the voltage coefficient K Electric power Is a quotient of:
T energizing 1 ＝X÷K Electric power
Then, relatively, the duty cycle X interrupts the power for a period T Power outage 1 ＝X-T Energizing 1 。
If the judgment result of the step S4 is NO, the step S6 is executed to judge the voltage coefficient K Electric power Whether or not it is smaller than a second preset value K 2 Wherein the second preset value K 2 The second preset value K can be obtained by reading the data stored in the chip 2 Should be less than 1, in this embodiment, the second preset value K 2 Take 0.9.
If the judgment result of the step S6 is yes, the step S7 is executed to control the electric heater to operate in the continuous mode.
If the judgment result of the step S6 is NO, determining the current K 2 ≤K Electric power ≤K 1 And executing a judging step S8, and judging whether the condition of starting the electric heater of the chassis is met for the first time after the unit is electrified. If yes, executing step S9, and controlling the electric heater to run in a continuous mode; if not, the step S10 is executed to control the electric heater to maintain the original mode operation.
In the execution of step S10, the primary mode is an operation mode in the last working cycle of the electric heater, and the primary mode is only divided into a continuous mode and an intermittent mode, wherein the intermittent mode includes the first intermittent mode and the second intermittent mode, and when the primary mode is determined to be the intermittent mode, the electric heater is controlled to operate in the second intermittent mode in the execution of step S10. That is, whether the original mode is the first intermittent mode or the second intermittent mode of the intermittent modes, the electric heater is controlled to operate in the second intermittent mode at this time.
In the second intermittent mode, the power-on duration T of the electric heater is within the working period X of the electric heater Energizing 2 For the working period X and the second preset value K of the electric heater 2 The product of:
T energizing 2 ＝X×K 2
In the present embodiment, K 2 Take 0.9. Then, relatively, the duty cycle X interrupts the power for a period T Power outage 2 ＝X-T Energizing 2 。
The chassis electric heater is a resistive load, and assuming that the resistance impedance of the electric heating belt is R and the unit power supply voltage is U, when the electric heating belt is electrified, the power consumed by the electric heating belt is as follows:
P＝U2/R
as U increases, the greater the power P consumed by the electric heating belt, the greater the amount of heat generated, and the greater the risk of overheating and burning out of the electric heating belt of the chassis, for example, when the electric heater of the chassis is operated at high voltage and high power for a long time.
A first preset value K 1 And a second preset value K 2 Is designed for grid voltage fluctuations. According to the execution of the above steps, if the supply ac voltage data U is available in And preset alternating voltage data U Presetting As the voltage coefficient K Electric power Is greater than a first preset value K 1 The ac input voltage is considered to be high, and at this time, in order to reduce the electric power loss caused by the continuous electric heater starting state and prevent the electric heater from being damaged due to the fact that the electric heater continuously operates for a long time and the power is too high, the electric heater is controlled to perform deicing by adopting a first intermittent mode which is dynamically adjusted according to the change of the voltage coefficient m.
If power supply AC voltage data U in And preset alternating voltage data U Presetting As the voltage coefficient K Electric power Less than a second preset value K 2 At the moment, the situation that the voltage and the power are too high is considered not to occur, and the continuous mode of continuously powering on the chassis electric heater is selected for deicing.
If the current voltage coefficient K is determined Electric power Greater than or equal to a second preset value K 2 And is less than or equal to a first preset value K 1 When and confirm that the chassis electric heater is not powered on for the first time and the original mode is in betweenIn the rest mode, the electric heater is controlled in a relatively fixed second intermittent mode.
After steps S11, S5, S7, S9, or S10 are executed, the routine returns to step S2 to determine whether the on condition of the electric heater of the chassis is satisfied.
In addition, after executing steps S5, S7, S9 or S10, the start time of the air conditioning unit entering the defrosting mode is delayed by a first preset duration, for example, the first preset duration is 5 minutes. The problem that the condensed water flows to the chassis to cause difficulty in defrosting due to the fact that the chassis has ice and enters defrosting at the same time of defrosting is avoided as much as possible.
In addition, after executing steps S5, S7, S9 or S10, the outdoor fan is controlled to perform a downshift operation within a second preset period of time. For example, the outdoor fan is operated in 15 th gear, and after the electric heater is started, the outdoor fan is controlled to be lowered to 14 th gear for 2 minutes. The external fan blows cold air during heating operation, so that the heat loss of the electric heating belt can be reduced when the rotating speed of the external fan is reduced when the electric heating belt of the chassis is started, and the deicing efficiency is not affected.
