Description
Technical Field
The invention relates to the technical field of air conditioners, in particular to a sterilization control method and device of an air conditioner, the air conditioner and a storage medium.
Background
Along with the health requirements of users on the air conditioner in the use process, the high-temperature sterilization function of the air conditioner becomes the focus of attention of related technical personnel, the high-temperature sterilization function of the air conditioner is to inactivate germs and viruses by utilizing the high temperature of an indoor heat exchanger, therefore, the high-temperature sterilization function is to control the temperature of a coil pipe of the indoor heat exchanger to be maintained above 56 ℃, the essence of the high-temperature sterilization is heating, the harsh heating working condition specified by the national standard is the maximum operation heating working condition, which is called as the thermotechnical working condition for short, namely, 27 ℃ of indoor dry and wet balls and 24 ℃ of outdoor dry and wet balls and 18 ℃. However, in practical applications, users can also use the high-temperature sterilization function of the air conditioner to perform sterilization at higher ambient temperature, such as summer, but in summer, the outdoor temperature generally exceeds 30 ℃, even can reach 40 ℃ or above, and is more severe than the high thermal condition specified by the national standard, at this time, in order to ensure the sterilization effect, the temperature of the heat exchanger coil must be controlled and maintained in a higher sterilization temperature range, so the condensation pressure of the corresponding refrigeration system is high, however, the higher the temperature in summer, the better the heat exchange coefficient is, so that the compressor must operate at a low frequency, such as 10Hz, that is, a heavy load, and a low frequency. When the air conditioner runs under heavy load and low frequency, the problem that the air conditioner drives the compressor to fail easily occurs, and the reliability of the compressor is low. Wherein, the principle that the heavy load low frequency drives the compressor to lose step and shut down does: the output torque of a compressor motor, such as a permanent magnet synchronous motor, is related to the motor speed or frequency, and when the frequency is reduced to a certain value, the output torque is rapidly reduced. When the compressor is at a low frequency, the fluctuation of the rotating speed is obvious due to the influence of the rotational inertia, for example, when the compressor is at 20Hz, the fluctuation range may be 15Hz-30Hz, when the compressor is at 20Hz, the output torque is limited, the torque current may be increased for dragging the load, and when the torque current reaches the upper limit, the drive may be stopped out of step. And, as shown in fig. 1, when the frequency of the compressor is lower than 30Hz, the lower the frequency, the lower the maximum condensing pressure boundary, in order to maintain the coil of the indoor heat exchanger at 56 ℃, the corresponding condensing pressure is at least 3.6 Mpa; the highest sterilization condensation temperature can not exceed the maximum condensation pressure 4.15MPa specified by the compressor, the corresponding condensation temperature is 64 ℃, and different refrigerants have different specified maximum condensation pressure boundaries and corresponding condensation temperatures.
Aiming at the sterilization function of the air conditioner, in the prior related technology, the air conditioner is controlled to enter a high-temperature sterilization mode and perform heating operation, whether the pressure ratio of high pressure and low pressure is greater than or equal to a preset ratio or whether the pressure difference is greater than or equal to a preset difference value is detected and judged, and if the pressure ratio is greater than or equal to the preset ratio or the pressure difference is greater than or equal to the preset difference value, at least one of increasing the rotating speed of an outdoor fan, reducing the frequency of a compressor, increasing the opening degree of a throttling device and increasing the rotating speed of an indoor fan is performed; if the pressure ratio is smaller than the preset ratio or the pressure difference is smaller than the preset difference value, whether the temperature of the indoor heat exchanger is lower than the first sterilization temperature or not is judged, and if yes, at least one of the air guide piece is adjusted to reduce the area of the air outlet, the rotating speed of the indoor fan is reduced, the frequency of the compressor is improved, the opening of the throttling device is reduced, the rotating speed of the outdoor fan is improved, and the electric auxiliary heat is started to improve the temperature of the indoor heat exchanger. This improves the sterilization effect.
However, the conventional sterilization control method only considers the improvement of the sterilization effect, but does not consider the reliability problem of the compressor during sterilization, and is easy to trigger the driving step-out fault shutdown when the indoor and outdoor ambient temperatures are high, and is easy to cause the problem of the over-standard pressure of the refrigeration system, thereby reducing the reliability of the operation of the compressor.

Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
Controlling the temperature of the indoor heat exchanger above 56 c for a period of time, such as 30 minutes and more, and also requiring the compressor to operate at a higher frequency is difficult to achieve using conventional control methods when the outdoor ambient temperature is high, such as high temperatures in summer. The higher the outdoor environment temperature is, the more easily the driving step-out fault shutdown is triggered, and the problems of over-standard pressure of the refrigeration system and the like are caused, for example, the operation reliability and the electric control driving reliability of the refrigeration system are greatly examined in hot weather of more than 40 ℃. In view of the above, the sterilization control method of the air conditioner according to the embodiment of the present invention needs to control the lowest frequency of the compressor to 30Hz or more in order to ensure the reliability of the operation of the compressor, and to take into account the hysteresis of the control of the condensing temperature instead of the pressure and the reliability of the control, as shown in fig. 1. The minimum reliability operation frequency corresponding to the maximum condensing pressure of different compressors is different. And when the outdoor environment temperature is high, such as high temperature in summer, and the air conditioner needs to be sterilized, the rotating speed of an outdoor direct current motor, the rotating speed of an indoor motor and the frequency of the compressor of the air conditioner are controlled according to the temperature value of the indoor heat exchanger and the priority order, so that the compressor is ensured to operate at a high frequency during high-temperature sterilization in summer, the problems of driving step-out shutdown and overhigh condensation pressure caused by low-frequency operation of the compressor are avoided, and the operation reliability of the compressor and the high-temperature sterilization reliability of the air conditioner are improved.
The following describes a sterilization control method for an air conditioner according to an embodiment of the present invention.
The sterilization control method of the air conditioner according to the embodiment of the present invention is described below with reference to fig. 2, and as described in fig. 2, the sterilization control method of the air conditioner according to the embodiment of the present invention includes at least steps S1 and S2.
Step S1, after receiving the sterilization instruction, determining whether the current environment meets a preset condition, where the preset condition includes: the indoor ambient temperature is greater than or equal to a first temperature threshold, and the outdoor ambient temperature is greater than or equal to a second temperature threshold.
In an embodiment, the preset condition is that the indoor ambient temperature is greater than or equal to the first temperature threshold, and the outdoor ambient temperature is greater than or equal to the second temperature threshold, and the ambient temperature is considered to be higher, that is, the air conditioner is in a high-temperature environment, such as summer. After receiving the sterilization instruction, it is necessary to determine whether the current environment meets a preset condition, thereby determining whether the current environment is a high-temperature environment. Specifically, the indoor environment temperature is, for example, denoted as Tin, the outdoor environment temperature is, for example, denoted as Tout, the first temperature threshold is, for example, denoted as T1, the second temperature threshold is, for example, denoted as T2, and it is determined whether the current environment meets the preset conditions, that is, whether the indoor environment temperature Tin is greater than or equal to the first temperature threshold T1, for example, Tin ≧ T1, and the outdoor environment temperature Tout is greater than or equal to the second temperature threshold T2, for example, Tout ≧ T2; if the indoor ambient temperature Tin and the outdoor ambient temperature Tout are met at the same time, the indoor ambient temperature Tin and the outdoor ambient temperature Tout are considered to be higher, for example, the current environment is in a high-temperature environment in summer. Or, the current season may be located through an APP (application) terminal bound to the air conditioner, where the background is set in advance with respect to each season and the indoor ambient temperature Tin and the outdoor ambient temperature Tout corresponding to each season, for example, if it is determined that the current city is beijing and the current time is 7 months, it is determined that the current city is in summer, and the current indoor ambient temperature Tin and the current outdoor ambient temperature Tout meet the preset conditions.
For example, the user may send a sterilization command through, but not limited to, an air conditioner remote controller or a related key on an operation interface on the body of the air conditioner, and after receiving the sterilization command, the air conditioner detects the indoor ambient temperature Tin and the outdoor ambient temperature Tout, and determines whether the current environment meets preset conditions, for example, the first temperature threshold T1 is 25 ℃, the second temperature threshold T2 is 24 ℃, when detecting that the indoor ambient temperature Tin is 27 ℃ and the outdoor ambient temperature Tout is 33 ℃, the indoor ambient temperature Tin is considered to be greater than the first temperature threshold T1, and the outdoor ambient temperature Tout is greater than the second temperature threshold T2, at this time, the current environment is considered to meet the preset conditions, and the current ambient temperature is higher, for example, in summer. Or after the air conditioner receives the sterilization instruction, the air conditioner positions the seasons of the current time at each place through the APP terminal, and if the current time is Beijing and July or August, the current environment is considered to meet the preset conditions, for example, the air conditioner is in a high-temperature working condition in summer.
Step S2, if the current environment meets the preset condition, controlling the air conditioner to enter a sterilization mode, wherein in the sterilization mode, the method includes: the method comprises the steps of controlling an outdoor direct current motor of the air conditioner to operate at a first preset rotating speed, controlling an indoor motor to operate at a second preset rotating speed and controlling a compressor to operate at a first preset frequency, simultaneously controlling an air deflector to be in a set position, obtaining a temperature value of an indoor heat exchanger after operating for a first preset time, adjusting one or more of the rotating speed of the outdoor direct current motor, the rotating speed of the indoor motor and the frequency of the compressor according to the temperature value of the indoor heat exchanger, and in the adjusting process, adjusting the rotating speed of the outdoor direct current motor at the highest priority and adjusting the frequency of the compressor at the lowest priority.
In an embodiment, when the current environment meets a preset condition, for example, high temperature in summer, the air conditioner is controlled to enter a sterilization mode for high temperature sterilization. The essence of sterilization is heating, so, in the sterilization mode, the air conditioner operates in the heating mode, the indoor environment temperature is high in summer, and in order to avoid the situation that the indoor environment temperature is too high and quickly reaches the set temperature of the air conditioner, so that the air conditioner is stopped when reaching the temperature, the set temperature Ts is set to be far greater than the upper limit temperature value of the settable temperature, for example, the upper limit value of the settable temperature is 32 ℃, and then the set temperature Ts is set to be 50 ℃. Meanwhile, the rotating speed of the outdoor direct current motor, the rotating speed of the indoor motor and the frequency of the compressor are correspondingly controlled.
It can be understood that when the sterilization function is started, the rotating speed of the outdoor direct current motor is reduced or increased, and the temperature of the indoor heat exchanger is reduced or increased along with the reduction or the increase; the rotating speed of the indoor motor is reduced, and the temperature of the indoor heat exchanger is increased along with the reduction of the rotating speed of the indoor motor; the frequency of the compressor decreases or increases, and the temperature of the indoor heat exchanger decreases or increases.
Specifically, the rotation speed of the outdoor dc motor is generally set to three or more gears, and when three gears are set, such as a high windshield rotation speed, a medium windshield rotation speed, and a low windshield rotation speed, they are respectively denoted as R _ H, R _ M and R _ L; or, when more than three gears are provided, for example, when 12 gears of rotation speed are provided, the highest windshield rotation speed is recorded as R12, and the lowest windshield rotation speed is recorded as R1. The speed of the indoor motor is typically provided with three or more gear positions, such as a high damper speed, e.g., r _ H, a medium damper speed, e.g., r _ M, and a low damper speed, e.g., r _ L.
Taking three gears of the outdoor direct current motor and the indoor motor as an example, the process of correspondingly controlling the rotating speed of the outdoor direct current motor, the rotating speed of the indoor motor and the frequency of the compressor after the air conditioner enters the sterilization mode is described.
After the air conditioner is controlled to enter the sterilization mode, the rotation speed of the outdoor direct current motor is controlled to be a first preset rotation speed, for example, the low windshield rotation speed R _ L is 600rpm, the indoor motor is controlled to be a second preset rotation speed, for example, the low windshield rotation speed R _ L is 800rpm, and the compressor is operated at a first preset frequency for a first preset time. Specifically, the first preset frequency of the compressor is the lowest frequency of high-temperature sterilization in summer, and is recorded as F _ low, for example, and the first preset frequency is greater than the minimum frequency of the air conditioner during normal heating. Therefore, in the high-temperature sterilization process of the air conditioner, the first preset frequency F _ low of the compressor is always controlled to be above the lowest frequency of the summer high-temperature sterilization, and the reliability of the operation of the compressor during the summer high-temperature sterilization can be ensured. Meanwhile, the air deflector is controlled to be in a set position, so that the air outlet direction of the air conditioner can be used for discharging air along the horizontal direction or discharging air at a certain inclined included angle with the horizontal direction, wherein the angle range of the inclined included angle can be 0-30 degrees, for example, the air deflector is controlled to be in the air flow position of a patio, so that the air deflector guides air flow to blow to a ceiling, hot air blown out by an indoor fan is reduced, and the comfort of a user is improved. The F _ low is a preset value, the F _ low values corresponding to different compressors are different, the F _ low is generally determined comprehensively by technical requirements in a specification of the compressor and a specific driving scheme of the air conditioner, and generally, the F _ low value is 35Hz at the minimum.
In order to satisfy the problems of reliability of the compressor and prevention of step-out of driving, the operation frequency of the compressor is defined to be operated at the lowest frequency F _ low of the summer pasteurization, and initially remains unchanged, may be increased if necessary, but cannot be decreased.
Further, after the operation for a first preset time, for example, 2 minutes, a temperature value of the indoor heat exchanger is obtained, for example, recorded as Tc. After the temperature value Tc of the indoor heat exchanger is obtained, one or more of the rotating speed of the outdoor direct current motor, the rotating speed of the indoor motor and the frequency of the compressor are adjusted according to the priority sequence and the temperature value Tc of the indoor heat exchanger, so that the rotating speed of the outdoor direct current motor, the rotating speed of the indoor motor and the frequency of the compressor can run at normal frequency or rotating speed, the problems of driving out-of-step shutdown and overhigh condensation pressure due to low-frequency running of the compressor are avoided, the temperature of the indoor heat exchanger is guaranteed to meet the sterilization temperature requirement, and meanwhile the running reliability of the compressor and the high-temperature sterilization reliability of the air conditioner during high-temperature sterilization are improved.
According to the sterilization control method of the air conditioner of the embodiment of the invention, when the current environment meets the preset conditions, the air conditioner is controlled to enter the sterilization mode, and high-temperature sterilization is carried out in the sterilization mode, namely, the outdoor direct current motor of the air conditioner is controlled to operate at a first preset rotating speed, the indoor motor operates at a second preset rotating speed and the compressor operates at a first preset frequency, after the air conditioner operates for a first preset time, the temperature value of the indoor heat exchanger is obtained, one or more of the rotating speed of the outdoor direct current motor, the rotating speed of the indoor motor and the frequency of the compressor is adjusted according to the priority sequence, so that the temperature value of the indoor heat exchanger can meet the temperature requirement of high-temperature sterilization, meanwhile, the frequency of the compressor is controlled to be at or above the lowest frequency during high-temperature sterilization, the rotating speed of the outdoor direct current motor and the rotating speed of the indoor motor are correspondingly controlled, and when the high-temperature sterilization is ensured, the compressor can normally operate under indoor and outdoor high-temperature environments, the problems that the compressor is driven to stop in a step-out mode due to low-frequency operation and the condensing pressure is too high are solved, and therefore the cost is not increased, and the reliability of operation of the compressor and the reliability of high-temperature sterilization of the air conditioner during high-temperature sterilization are improved.
In the embodiment of the present invention, an interval formed by an upper limit sterilization temperature value and a lower limit sterilization temperature value is defined as a sterilization temperature interval, the lower limit sterilization temperature value is, for example, a first preset sterilization temperature value, which is denoted as Tc1, and the upper limit sterilization temperature value is, for example, a second preset sterilization temperature value, which is denoted as Tc2, the temperature value Tc of the indoor heat exchanger is between the first preset sterilization temperature value Tc1 and the second preset sterilization temperature value Tc2, and when, for example, Tc1 is not less than Tc < Tc2, the temperature value Tc of the indoor heat exchanger is considered to be in the sterilization temperature interval.
Specifically, the first predetermined sterilization temperature value Tc1 is determined by the minimum sterilization temperature, typically 56 ℃, the second predetermined sterilization temperature value Tc2 is determined by the maximum condensing pressure of the compressor specification, the condensing temperature corresponding to the maximum condensing pressure is 64 ℃, and the corresponding second predetermined sterilization temperature value Tc2 is, for example, 60 ℃. The adjustment process of the rotation speed of the outdoor dc motor, the rotation speed of the indoor motor, and the frequency of the compressor will be described below by taking the first predetermined sterilization temperature value Tc1 as 56 ℃ and the second predetermined sterilization temperature value Tc2 as 60 ℃.
In some embodiments, adjusting one or more of a rotational speed of the outdoor dc motor, a rotational speed of the indoor motor, and a frequency of the compressor based on the temperature value of the indoor heat exchanger includes: if the temperature value of the indoor heat exchanger is smaller than the first preset sterilization temperature value, controlling the outdoor direct current motor to gradually increase the rotating speed according to a first preset step length on the basis of the first preset rotating speed so as to correspondingly increase the temperature value of the indoor heat exchanger; in the process of increasing the rotating speed of the outdoor direct current motor, if the temperature value of the indoor heat exchanger is increased to be greater than or equal to a first preset sterilization temperature value and less than a second preset sterilization temperature value, and the rotating speed of the outdoor direct current motor is less than or equal to the highest rotating speed threshold value of the outdoor direct current motor at the moment, if the rotating speed of the high wind gear is R _ H, the outdoor direct current motor is controlled to operate according to the rotating speed of the outdoor direct current motor at the moment; and if the temperature value of the indoor heat exchanger is smaller than the first preset sterilization temperature value and the rotating speed of the outdoor direct current motor is increased to the maximum rotating speed threshold value of the outdoor direct current motor at the moment, controlling the indoor motor to gradually reduce the rotating speed according to a second preset step length on the basis of a second preset rotating speed so as to correspondingly increase the temperature value of the indoor heat exchanger.
For example, after the air conditioner operates for a first preset time, for example, after the air conditioner operates for 2 minutes, the temperature value Tc of the indoor heat exchanger is obtained, if the temperature value Tc of the indoor heat exchanger is 50 ℃, the temperature value Tc of the indoor heat exchanger is considered to be smaller than a first preset sterilization temperature value Tc1, that is, Tc is smaller than Tc1, the temperature value Tc of the indoor heat exchanger is considered to be lower, and the sterilization effect cannot be ensured, at this time, the temperature value Tc of the indoor heat exchanger needs to be increased, so that the temperature value Tc of the indoor heat exchanger is between the first preset sterilization temperature value Tc1 and a second preset sterilization temperature value Tc2, that is, the temperature value Tc of the indoor heat exchanger is within a sterilization temperature range, at this time, one or more of the rotating speed of the outdoor direct current motor, the rotating speed of the indoor motor and the frequency of the compressor needs to be sequentially adjusted according to the priority order of the rotating speed of the outdoor direct current motor, the rotating speed of the indoor motor and the frequency of the compressor, since the priority for adjusting the rotation speed of the outdoor dc motor is highest, when the temperature value Tc of the indoor heat exchanger is less than the first preset sterilization temperature value Tc1, the rotation speed of the outdoor dc motor is controlled first.
Specifically, the outdoor direct current motor is controlled to gradually increase the rotation speed of the outdoor direct current motor according to a first preset step based on a first preset rotation speed, where the first preset step is, for example, denoted as Δ R, the outdoor direct current motor gradually increases the rotation speed according to the first preset step Δ R based on a low windshield rotation speed R (0) and R _ L, and for example, R (1) and R (0) +50 are 600 and R _ L, 650 and 650rpm, R (2) and R (1) +50 and 650+50 are 700 and 700rpm, and so on, and the rotation speed of the outdoor direct current motor is gradually increased according to R (n +1) and R (n) + Δ R. In the process of increasing the rotation speed of the outdoor dc motor, the temperature value Tc of the indoor heat exchanger needs to be periodically obtained every 10 seconds, for example, every 10 seconds, and the temperature value Tc of the indoor heat exchanger is obtained again, for example, after 10 seconds, the temperature value Tc of the indoor heat exchanger is detected to be 58 ℃, then it is considered that the temperature value Tc of the indoor heat exchanger is increased to be greater than or equal to the first preset sterilization temperature value Tc1 and less than the second preset sterilization temperature value Tc2, and the rotation speed of the outdoor dc motor is less than or equal to the maximum rotation speed threshold of the outdoor dc motor at this time, it is considered that the temperature value Tc of the indoor heat exchanger can be increased to be between the first preset sterilization temperature value Tc1 and the second preset sterilization temperature value Tc2 only by increasing the rotation speed of the outdoor dc motor, that is, at this time, it is not necessary to continuously increase the rotation speed of the outdoor dc motor, and the outdoor dc motor is controlled to operate according to the rotation speed at this time, so that the temperature value Tc of the indoor heat exchanger is maintained within the sterilization temperature interval.
If the obtained temperature value Tc of the indoor heat exchanger is less than the first preset sterilization temperature value Tc1 and there is no obvious trend of rising, and the rotation speed of the outdoor direct current motor has risen to the maximum rotation speed threshold value R _ H of the outdoor direct current motor, for example, the rotation speed of the outdoor direct current motor has risen to R ═ 900rpm, it is considered that the temperature value Tc of the indoor heat exchanger cannot be increased to the sterilization temperature interval only by increasing the rotation speed of the outdoor direct current motor, at this time, the rotation speed of the indoor motor needs to be adjusted according to the priority adjustment sequence, and when the rotation speed of the indoor motor is adjusted, the indoor motor is controlled to gradually decrease the rotation speed according to the second preset step length on the basis of the second preset rotation speed, so as to correspondingly increase the temperature value Tc of the indoor heat exchanger. By comparing the size relationship between the temperature value Tc of the indoor heat exchanger and the first preset sterilization temperature value Tc1 and the second preset sterilization temperature value Tc2, when the temperature value Tc of the indoor heat exchanger is smaller than the first preset sterilization temperature value Tc1, the rotating speeds of the outdoor direct current motor and the indoor motor are adjusted according to the priority adjusting sequence, and therefore the temperature value Tc of the indoor heat exchanger is increased, and the temperature value Tc of the indoor heat exchanger is increased to the sterilization temperature interval.
In some embodiments, after the controlling the indoor motor to gradually decrease the rotation speed according to the second preset step length based on the second preset rotation speed, the method further includes: in the process of reducing the rotating speed of the indoor motor, if the temperature value of the indoor heat exchanger is increased to be greater than or equal to a first preset sterilization temperature value and less than a second preset sterilization temperature value, and the rotating speed of the indoor motor is greater than or equal to the lowest rotating speed threshold value of the indoor motor at the moment, controlling the indoor motor to operate according to the rotating speed of the indoor motor at the moment; if the temperature value of the indoor heat exchanger is smaller than the first preset sterilization temperature value and the rotating speed of the indoor motor is reduced to the lowest rotating speed threshold value of the indoor motor at the moment, controlling the compressor to increase the frequency gradually according to the preset frequency increment on the basis of the first preset frequency so as to correspondingly increase the temperature value of the indoor heat exchanger until the temperature value of the indoor heat exchanger is larger than or equal to the first preset sterilization temperature value and smaller than the second preset sterilization temperature value.
For example, in the process of reducing the rotation speed of the indoor motor, the indoor motor needs to be controlled to gradually reduce the rotation speed according to a second preset step length based on a second preset rotation speed threshold value to increase the temperature value Tc of the indoor heat exchanger, for example, the second preset step length is denoted as Δ r, at this time, the indoor motor is controlled to gradually reduce the rotation speed of the indoor motor according to the second preset step length Δ r based on the low windshield rotation speed r (0) -r _ L-800 rpm, that is, r (1) -r (0) -100-800-100-700-600-rpm, r (2) -r (1) -100-700-100-600-rpm, and so on, the rotation speed of the indoor motor is gradually reduced according to r (n +1) -r (n) - Δ r- (n) -r. In the process of reducing the rotating speed of the indoor motor, the temperature Tc of the indoor heat exchanger needs to be obtained, if the temperature value Tc of the indoor heat exchanger is increased to be greater than or equal to a first preset sterilization temperature value Tc1 and less than a second preset sterilization temperature value Tc2, and the rotating speed of the indoor motor is greater than or equal to the lowest rotating speed threshold of the indoor motor at the moment, the rotating speed of the indoor motor is considered to be adjusted after the rotating speed of the outdoor direct current motor is adjusted to be the highest rotating speed threshold, so that the outdoor direct current motor and the indoor motor are adjusted together, the temperature value Tc of the indoor heat exchanger can be increased to a sterilization temperature interval, at the moment, the rotating speed of the indoor motor does not need to be continuously reduced, only the indoor motor is controlled to operate according to the rotating speed at the moment, and the temperature value Tc of the indoor heat exchanger is maintained in the sterilization temperature interval.
If the temperature value Tc of the indoor heat exchanger is less than the first preset sterilization temperature value Tc1 and has no obvious trend of rising, and the rotation speed of the indoor motor has been reduced to the minimum rotation speed threshold of the indoor motor at this time, for example, the rotation speed of the indoor motor has been reduced to r ═ 400rpm, it is considered that the temperature value Tc of the indoor heat exchanger cannot be increased to the sterilization temperature range by increasing the rotation speed of the outdoor dc motor and reducing the rotation speed of the indoor motor, and at this time, according to the priority adjustment sequence, the frequency of the compressor needs to be adjusted so as to increase the temperature value Tc of the indoor heat exchanger to the sterilization temperature range. In other words, if the temperature value Tc of the indoor heat exchanger is always smaller than the first preset sterilization temperature value Tc1, and the rotation speed of the outdoor dc motor has been increased to the maximum rotation speed threshold R _ H of the outdoor dc motor according to R (n +1) ═ R (n) +. DELTA.r, the rotation speed of the indoor motor is controlled to be decreased to increase the temperature value Tc of the indoor heat exchanger, i.e. R (n +1) ═ R (n) — Δ R, where R (0) ═ R _ L, and the minimum value of R (n +1) is the minimum rotation speed rmin of reliable operation, i.e. the minimum rotation speed threshold of the indoor motor.
Further, when the rotation speed of the outdoor dc motor has increased to the maximum rotation speed threshold of the outdoor dc motor, and the rotation speed of the indoor motor has decreased to the minimum rotation speed threshold of the indoor motor, at this time, the temperature value of the indoor heat exchanger is still less than the first preset sterilization temperature value Tc1, the compressor is controlled to increase the frequency successively according to a preset frequency increment based on the first preset frequency, for example, the compressor is controlled to increase the frequency successively according to the preset frequency increment based on F (0) ═ F _ low, that is, F (1) ═ F (0) +5 ═ 35+5 ═ 40Hz, and the compressor is controlled to increase the temperature value Tc of the indoor heat exchanger successively according to F (n +1) ═ F ++ [ delta ] F, so as to increase the temperature value Tc of the indoor heat exchanger until the temperature value Tc of the indoor heat exchanger is greater than or equal to the first preset sterilization temperature value Tc1 and less than the second preset sterilization temperature value Tc 2. By comparing the size relationship between the temperature value Tc of the indoor heat exchanger and the first preset sterilization temperature value Tc1 and the second preset sterilization temperature value Tc2, when the temperature value Tc of the indoor heat exchanger is smaller than the first preset sterilization temperature value Tc1, the rotating speed of the outdoor direct current motor, the rotating speed of the indoor motor and the frequency of the compressor are adjusted according to the priority adjusting sequence, so that the temperature value Tc of the indoor heat exchanger is in a sterilization temperature range, the sterilization effect of the air conditioner is ensured, the operating frequency of the compressor is considered, the compressor frequency is not too low to cause shutdown, and the operation reliability of the compressor and the high-temperature sterilization reliability of the air conditioner during high-temperature sterilization are improved. In other words, if the rotation speed of the outdoor dc motor has increased to the maximum rotation speed threshold R _ H and the rotation speed of the indoor motor has decreased to the minimum rotation speed threshold rmin, and at this time, the temperature value Tc of the indoor heat exchanger is still less than the first preset sterilization temperature value Tc1, the frequency of the compressor is controlled to increase the temperature value Tc of the indoor heat exchanger, i.e. F (n +1) ═ F (n) ++ [ delta ] F, where F (0) ═ F _ low, until Tc1 ≦ Tc < Tc2 is satisfied.
In some embodiments, adjusting one or more of a rotational speed of the outdoor dc motor, a rotational speed of the indoor motor, and a frequency of the compressor based on the temperature value of the indoor heat exchanger includes: and if the temperature value of the indoor heat exchanger is greater than or equal to the first preset sterilization temperature value and less than the second preset sterilization temperature value, controlling the outdoor direct current motor to continuously operate at the first preset rotating speed so as to maintain the temperature value of the indoor heat exchanger.
In a specific embodiment, after the air conditioner operates for a first preset time, for example, after 2 minutes, a temperature value Tc of the indoor heat exchanger is obtained, and if the temperature value Tc of the indoor heat exchanger is greater than or equal to a first preset sterilization temperature value Tc1 and less than a second preset sterilization temperature value Tc2, for example, Tc1 is not greater than Tc < Tc2, it is determined that the temperature value Tc of the indoor heat exchanger is in a sterilization temperature interval, at this time, the outdoor direct current motor is controlled to operate continuously at a first preset rotation speed, for example, the outdoor direct current motor is controlled to operate continuously at R of 600rpm, so that the temperature value Tc of the indoor heat exchanger is maintained in the sterilization temperature interval, and thus, the sterilization effect of the air conditioner is ensured.
In some embodiments, adjusting one or more of a rotational speed of the outdoor dc motor, a rotational speed of the indoor motor, and a frequency of the compressor based on the temperature value of the indoor heat exchanger includes: if the temperature value of the indoor heat exchanger is greater than the second preset sterilization temperature value, controlling the outdoor direct current motor to gradually reduce the rotating speed according to a first preset step length on the basis of a first preset rotating speed so as to correspondingly reduce the temperature value of the indoor heat exchanger; in the process of reducing the rotating speed of the outdoor direct current motor, if the temperature value of the indoor heat exchanger is reduced to be greater than or equal to a first preset sterilization temperature value and less than a second preset sterilization temperature value, and the rotating speed of the outdoor direct current motor is greater than or equal to the lowest rotating speed threshold value of the outdoor direct current motor at the moment, controlling the outdoor direct current motor to operate according to the rotating speed of the outdoor direct current motor at the moment; and if the temperature value of the indoor heat exchanger is greater than the second preset sterilization temperature value and the rotating speed of the outdoor direct current motor is reduced to the lowest rotating speed threshold value of the outdoor direct current motor at the moment, controlling the outdoor direct current motor to be turned off, and controlling the outdoor direct current motor to be turned on again until the temperature value of the indoor heat exchanger is less than the first preset sterilization temperature value, and operating according to the lowest rotating speed threshold value of the outdoor direct current motor. The first preset rotation speed R (0) of the outdoor direct current motor is equal to R _ L, the minimum rotation speed threshold of the outdoor direct current motor is recorded as Rmin, and Rmin is lower than R _ L.
Specifically, after the air conditioner is operated for a first preset time, for example, after the air conditioner is operated for 2 minutes, the temperature value Tc of the indoor heat exchanger is obtained, and if the temperature value Tc of the indoor heat exchanger is 61 ℃, the temperature value Tc of the indoor heat exchanger is considered to be greater than a second preset sterilization temperature value Tc2, that is, Tc is greater than Tc2, at this time, the temperature value Tc of the indoor heat exchanger needs to be reduced so that the temperature value Tc of the indoor heat exchanger is between a first preset sterilization temperature value Tc1 and a second preset sterilization temperature value Tc2, that is, the temperature value Tc of the indoor heat exchanger is in a sterilization temperature range, at this time, according to a priority adjustment sequence of the rotating speed of the outdoor direct current motor, the rotating speed of the indoor motor and the frequency of the compressor, one or more of the rotating speed of the outdoor direct current motor, the rotating speed of the indoor motor and the frequency of the compressor are adjusted, and since the priority for adjusting the rotating speed of the outdoor direct current motor is highest, therefore, when the temperature value Tc of the indoor heat exchanger is greater than the second preset sterilization temperature value Tc2, the rotation speed of the outdoor dc motor is controlled first. Specifically, the outdoor dc motor is controlled to gradually decrease the rotation speed according to a first preset step based on a first preset rotation speed, where the first preset step is, for example, denoted as Δ R, based on a low windshield rotation speed R (0) ═ R _ L ═ 600rpm, the rotation speed of the outdoor dc motor is gradually decreased according to the first preset step Δ R, for example, R (1) ═ R (0) -50 ═ R600-50 ═ 550rpm, R (2) ═ R (1) -50 ═ R550-50 ═ 500rpm, and so on, the rotation speed of the outdoor dc motor is gradually decreased according to R (n +1) ═ R (n) — (n) R, a preset time is required to be a period in the process of decreasing the rotation speed of the outdoor dc motor, the temperature value of the indoor heat exchanger is periodically obtained, for example, every 10s, and then, the temperature value of the indoor heat exchanger is decreased to be greater than or equal to the first preset rotation speed and smaller than a second preset sterilization temperature value 1, and the temperature value of the indoor heat exchanger is periodically obtained, for example, every 10s, and then, the temperature value of the indoor heat exchanger is obtained, and after 10s is decreased to be greater than the first preset sterilization 1 Setting a sterilization temperature value Tc2, and at the moment, the rotating speed of the outdoor direct current motor is less than or equal to the maximum rotating speed threshold value of the outdoor direct current motor, then it is considered that the temperature value Tc of the indoor heat exchanger can be reduced to be between the first preset sterilization temperature value Tc1 and the second preset sterilization temperature value Tc2 only by reducing the rotating speed of the outdoor direct current motor, namely, the temperature value Tc is reduced to be within a sterilization temperature range, at the moment, the rotating speed of the outdoor direct current motor does not need to be controlled continuously to reduce the rotating speed, the outdoor direct current motor is controlled to operate according to the rotating speed at the moment, and the temperature value Tc of the indoor heat exchanger is maintained within the sterilization temperature range.
If the temperature value Tc of the indoor heat exchanger is greater than the second preset sterilization temperature value Tc2 and there is no significant trend of decreasing, for example, the temperature value Tc of the indoor heat exchanger is 62 ℃ > 60 ℃, and the rotation speed of the outdoor dc motor has been reduced to the minimum rotation speed threshold Rmin of the outdoor dc motor at this time, for example, the rotation speed of the outdoor dc motor has been reduced to R of 150rpm, it is considered that the temperature value Tc of the indoor heat exchanger cannot be reduced to the sterilization temperature range only by reducing the rotation speed of the outdoor dc motor, at this time, the outdoor dc motor is controlled to be turned OFF, for example, the outdoor dc motor is controlled to be in an OFF state, so as to rapidly reduce the temperature value Tc of the indoor heat exchanger until the temperature value Tc of the indoor heat exchanger is reduced to be less than the first preset sterilization temperature value Tc1, for example, the temperature value Tc of the indoor heat exchanger is 55 ℃ < 56 ℃, at this time, the outdoor dc motor is controlled to be turned on again, and the outdoor dc motor is controlled to operate at the minimum rotation speed threshold, for example, the external dc motor is controlled to run at R150 rpm. When the temperature value Tc of the indoor heat exchanger is greater than the second preset sterilization temperature threshold value, the temperature value Tc of the indoor heat exchanger is controlled between the first preset sterilization temperature value Tc1 and the second preset sterilization temperature value Tc2 by controlling the rotating speed of the outdoor direct current motor or controlling the outdoor direct current motor to be turned on or turned off, and therefore the high-temperature sterilization effect of the air conditioner is guaranteed.
In some embodiments, after the outdoor dc motor is controlled to be turned on again and operated according to the minimum rotation speed threshold of the outdoor dc motor, the method further includes: if the temperature value of the indoor heat exchanger is increased to be greater than or equal to a first preset sterilization temperature value and less than a second preset sterilization temperature value, controlling the outdoor direct current motor to be continuously started and operate according to the minimum rotating speed threshold value of the outdoor direct current motor, controlling the outdoor direct current motor to be closed until the temperature value of the indoor heat exchanger is increased to be greater than the second preset sterilization temperature value, correspondingly reducing the temperature value of the indoor heat exchanger, and controlling the outdoor direct current motor to be started and operate according to the minimum rotating speed threshold value of the outdoor direct current motor until the temperature value of the indoor heat exchanger is reduced to be less than the first preset sterilization temperature value; the above processes are repeatedly executed to alternately control the outdoor direct current motor to be turned on or turned off.
For example, the outdoor dc motor is controlled to be turned on again, and after the outdoor dc motor is operated according to the minimum rotational speed threshold of the outdoor dc motor, the temperature value Tc of the indoor heat exchanger continues to be periodically obtained, if the temperature value Tc of the indoor heat exchanger is increased to be greater than or equal to the first preset sterilization temperature value Tc1 and less than the second preset sterilization temperature value Tc2, for example, the temperature value Tc of the indoor heat exchanger is 59 ℃, the outdoor dc motor is controlled to be turned on continuously, and the outdoor dc motor is operated according to the minimum rotational speed threshold of the outdoor dc motor, for example, the outdoor dc motor is operated according to the minimum rotational speed threshold R of 150rpm, until the temperature value Tc of the indoor heat exchanger is increased again to be greater than the second preset sterilization temperature value Tc2, for example, the temperature value Tc of the indoor heat exchanger is greater than 60 ℃, the outdoor dc motor is controlled to be turned off for reducing the temperature value of the indoor heat exchanger Tc until the temperature value Tc of the indoor heat exchanger is reduced to be less than the first preset sterilization temperature value Tc1, and controlling the outdoor direct current motor to be started again, controlling the outdoor direct current motor to operate at the lowest rotating speed threshold, repeatedly executing the process, and alternately controlling the outdoor direct current motor to be started or closed so that the temperature value Tc of the indoor heat exchanger is kept between the first preset sterilization temperature value Tc1 and the second preset sterilization temperature value Tc 2. Therefore, the sterilization effect of the air conditioner is ensured, the running frequency of the compressor is not influenced, the compressor is not too low to stop, and the running reliability of the compressor and the high-temperature sterilization reliability of the air conditioner are improved during high-temperature sterilization. In other words, when the temperature value Tc of the indoor heat exchanger is between the first preset sterilizing temperature value Tc1 and the second preset sterilizing temperature value Tc2, the outdoor dc motor is ON and the rotation speed is Rmin or OFF, depending ON the state of the outdoor dc motor at the last detection cycle. If the outdoor direct current motor is ON and the rotating speed is Rmin in the previous period, the outdoor direct current motor is kept ON and the rotating speed is Rmin in the current period, and if the outdoor direct current motor is OFF in the previous period, the outdoor direct current motor is kept OFF in the current period, namely the outdoor direct current motor is controlled to be switched between OFF and the lowest reliable running rotating speed Rmin.
Fig. 3 is a schematic diagram illustrating a corresponding relationship between a rotation speed of an outdoor dc motor and a temperature value of an indoor heat exchanger according to an embodiment of the present invention. It can be seen that, after the rotation speed of the outdoor dc motor runs for a period of time at the lowest rotation speed threshold of the outdoor dc motor, the temperature value Tc of the indoor heat exchanger is still greater than the second preset sterilization temperature value Tc2, when the outdoor dc motor is stopped, that is, the outdoor dc motor is controlled to be in the OFF state, at this time, the evaporation pressure of the refrigeration system is rapidly reduced, and the condensation pressure is driven to be rapidly reduced, so that the temperature value Tc of the indoor heat exchanger is certainly smaller than the first preset sterilization temperature value Tc 1.
In some embodiments, in the sterilization mode, further comprising: and if the time accumulation that the temperature value of the indoor heat exchanger is greater than the first preset sterilization temperature value reaches the second preset time, controlling the air conditioner to exit the sterilization mode. Specifically, after the air conditioner enters the sterilization mode, the time that the temperature value Tc of the indoor heat exchanger is greater than or equal to the first preset sterilization temperature value Tc1 is counted, namely, the time that Tc is greater than or equal to Tc1 is accumulated, when the accumulated time reaches a second preset time, for example, 40 minutes, the sterilization time of the air conditioner in the sterilization mode is considered to meet the sterilization time requirement, and at the moment, the air conditioner is controlled to exit the sterilization mode.
