It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Supercooling phenomenon: when the ambient temperature reaches (is less than or equal to) the set temperature value, the temperature actually detected by the air conditioner does not reach (is less than or equal to) the set temperature value, and the air conditioner still performs refrigeration until the temperature detected by the air conditioner reaches (is less than or equal to) the set temperature value, and the air conditioner stops refrigeration at the moment, but the actual temperature is lower than the set temperature value, so that the supercooling phenomenon is caused.
Overheating phenomenon: when the ambient temperature reaches (is greater than or equal to) the set temperature value, the temperature actually detected by the air conditioner does not reach (is greater than or equal to) the set temperature value, heating still can be carried out, the air conditioner can not stop heating until the temperature detected by the air conditioner reaches (is greater than or equal to) the set temperature value, but the actual temperature is higher than the set value, and an overheating phenomenon is caused.
The invention provides a temperature compensation method for air conditioner detection, which aims to enable an environment temperature value detected by an air conditioner to be the same as or more approximate to an actual environment temperature value, stop refrigeration or heating after reaching a set temperature value and avoid supercooling or overheating. The air conditioner comprises a wire controller, wherein a temperature detection device, such as an environment temperature sensing bulb, is arranged on the wire controller and used for detecting the environment temperature of the environment. And a temperature detection device, such as an environment temperature sensing bulb, is arranged on the inner machine of the air conditioner and is used for detecting the environment temperature of the environment.
Fig. 1 is a schematic method diagram of an embodiment of a method for compensating a detected temperature of an air conditioner according to the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the air conditioner detection temperature compensation method includes at least step S110, step S120, and step S130.
Step S110, obtaining a temperature average value of the ambient temperature detected by the temperature detection device on the air conditioner internal unit and the ambient temperature detected by the temperature detection device on the air conditioner line controller.
Specifically, after the compressor is started, the air conditioner detection temperature compensation logic is started. The temperature average value may be an arithmetic average value of the ambient temperature detected by the temperature detection device on the internal unit and the ambient temperature detected by the temperature detection device on the line controller, for example, the temperature T detected by the temperature sensing bulb reading the environment of the internal unitInner partTemperature T detected by environment temperature sensing bulb of line controllerThreadAnd obtaining the average value T of the temperatureAre all made of＝(TThread+TInner part)/2。
Preferably, the temperature average value may be a weighted average value of the ambient temperature detected by the temperature detection device on the internal unit and the ambient temperature detected by the temperature detection device on the line controller. For example, since the line controller is often placed in an area where the user is frequently active, the weight (for example, 60%) of the ambient temperature detected by the temperature detection device on the line controller may be set to be greater than the weight (for example, 40%) of the ambient temperature detected by the temperature detection device on the indoor unit. The compensated indoor environment temperature obtained by the weighted average value is more accurate and can better meet the actual requirements of users.
And step S120, acquiring the temperature of the indoor heat exchanger of the air conditioner, and determining whether the temperature compensation of the air conditioner detection is needed according to whether the temperature of the indoor heat exchanger meets a preset condition.
Specifically, if the temperature of the indoor heat exchanger meets a preset condition, it is determined that the compensation of the air conditioner detection temperature is required, otherwise, it is determined that the compensation of the air conditioner detection temperature is not required. The temperature of the indoor heat exchanger can be specifically the tube temperature of the indoor heat exchanger (evaporator), and can be detected through an evaporator temperature sensing bulb. The preset condition may specifically include that when the air conditioner is in a heating mode, the temperature of the indoor heat exchanger is greater than or equal to a first temperature value, and/or when the air conditioner is in a cooling mode, the temperature of the indoor heat exchanger is less than or equal to a second temperature value. That is, when the air conditioner is in a heating mode, whether the temperature C of the indoor heat exchanger is greater than or equal to a first temperature value E1 is judged, namely whether C is greater than or equal to E1, and if so, the compensation of the detected temperature of the air conditioner is determined to be needed; if not, determining that the compensation of the air conditioner detection temperature is not needed; when the air conditioner is in a refrigeration mode, judging whether the temperature C of the indoor heat exchanger is less than or equal to a second temperature value E2, namely whether C is less than or equal to E2, and if so, determining that the temperature detected by the air conditioner needs to be compensated; and if not, determining that the air conditioner detection temperature compensation is not needed. For example, in the cooling mode of the air conditioner, the tube temperature of the indoor heat exchanger may drop, if the tube temperature does not reach a certain temperature, the complete machine may lack fluorine or other abnormalities may cause a poor cooling effect, if the cooling effect is poor, the compensation is still performed, which causes over-compensation, and the situation in the heating mode is similar, so that when the tube temperature reaches a certain temperature value, the air conditioner has cooled or heated to a certain degree, and then the temperature compensation is performed.
And step S130, if the compensation is determined to be needed, compensating the air conditioner detection temperature according to the temperature average value and the duration time that the temperature of the indoor heat exchanger meets the preset condition.
Specifically, after the duration time that the temperature of the indoor heat exchanger meets the preset condition reaches different time, different air conditioner detection temperature compensation is performed respectively.
Fig. 2 is a schematic flow chart of a specific embodiment of the step of compensating the detected temperature of the air conditioner according to the average temperature value and the duration of time for which the temperature of the indoor heat exchanger satisfies the preset condition.
As shown in fig. 2, in one embodiment, step S130 includes step S131 and step S132.
Step S131, determining a corresponding temperature compensation value according to the duration time that the temperature of the indoor heat exchanger meets the preset condition.
Specifically, there is a direct relationship between the amount of cooling and heating of the air conditioner and the operation time of the compressor, and the longer the operation time is, the larger the amount of cooling and heating of the whole machine is, the different compensation is needed, therefore, different durations correspond to different temperature compensation values, for example, when the duration reaches T1, the compensation value T isSupplement deviceY 1; the duration reaches T2, the compensation value TSupplement deviceY 2; …, respectively; the duration reaches tn, the compensation value TSupplement device＝yn。
The temperature compensation values corresponding to different durations may be preset through experiments, for example, when the temperature of the indoor heat exchanger satisfies the preset condition, the ambient temperature values at different indoor positions are detected and the average value of the ambient temperatures at different indoor positions is calculated as the actual ambient temperature value TRing (C)Or detecting the environmental temperature value of the frequently active area of the indoor user as the actual environmental temperature value TRing (C)And meanwhile, acquiring the average temperature value of the ambient temperature detected by the temperature detection device on the air conditioner indoor unit and the ambient temperature detected by the temperature detection device on the air conditioner wire controller, and determining a corresponding compensation value according to the average temperature value and the actual ambient temperature value when the temperature of the indoor heat exchanger meets the preset condition for different durations. The duration may be at least one preset duration, e.g., 1 hour, 2 hours. For example, after the duration that the indoor heat exchanger temperature satisfies C ≦ E2 reaches 1 hour, the actual ambient temperature is detected as TRing (C)35 deg.C, the temperature detected by the temperature detector on the wire controller is TThread38 ℃, the temperature detected by the temperature detection device on the inner machine is TInner part34 ℃, then: actual ambient temperature TRing (C)＝(TThread+TInner part)/2+TSupplement device，TRing (C)、TThread、TInner partFor constant value, T is obtainedSupplement deviceA value of (d); heat exchange in roomAfter the temperature of the device meets the condition that the duration time of E2 is less than or equal to C reaches 2 hours, detecting that the actual environment temperature is TRing (C)The temperature detected by the temperature detector on the wire controller is T at 20 DEG CThreadWhen the temperature is 25 ℃, the temperature detection device on the inner machine detects the temperature as TInner partAt 18 ℃, T is also obtained from the above equationSupplement deviceA value of (d); t derived from the difference in durationSupplement deviceDifferent values are obtained, and then the temperature compensation values T corresponding to different durations are obtained through numerical statistical analysisSupplement device。
And S132, compensating the temperature average value according to the determined temperature compensation value to obtain the compensated air conditioner detection temperature.
In one specific embodiment, after the corresponding temperature compensation value is determined, the sum of the temperature compensation value and the temperature average value is used as the compensated air conditioner detection temperature.
For example, the determined temperature compensation value is TSupplement deviceAverage temperature value of TAre all made ofAnd the compensated air conditioner detection temperature is TRing (C)＝TAre all made of+TSupplement device. And the compensated air conditioner detection temperature is the ambient temperature value according to which the air conditioner is controlled.
In another embodiment, the temperature compensation value needs to be corrected according to different heating and cooling capacities of the compressor (such as the influence of the internal and external fans, the influence of weather changes, and the like). Specifically, a correction coefficient of the temperature compensation value is determined according to the temperature change rate of the temperature of the indoor heat exchanger; and taking the sum of the product of the temperature compensation value and the correction coefficient and the temperature average value as the compensated air conditioner detection temperature.
The temperature change rate of the indoor heat exchanger temperature may specifically be a temperature change rate D at which the indoor heat exchanger temperature (e.g., an indoor heat exchanger tube temperature) changes from T1 to T2. For example, the temperature change rate sections of different temperatures of the indoor heat exchanger may correspond to different temperature compensation value correction coefficients, and the different temperature compensation value correction coefficients corresponding to the temperature change rate sections of different temperatures of the indoor heat exchanger may be determined through experiments. For example, D ≦ N1, correction coefficient k ═ k 0; d is more than or equal to N1 and less than or equal to N2, and a correction coefficient k is k 1; d is more than or equal to N2 and less than or equal to N3, and a correction coefficient k is k 2; … …, respectively; n (m-1) is more than or equal to D and less than or equal to Nm, and a correction coefficient k is k (m-1); d is more than or equal to Nm, and the correction coefficient k is km.
For example, the determined temperature compensation value is TSupplement deviceAverage temperature value of TAre all made ofAnd correcting the coefficient k, wherein the compensated air conditioner detection temperature is TRing (C)＝TAre all made of+k*TSupplement device. And determining a compensation temperature correction coefficient according to different intervals of the temperature change rate of the indoor heat exchanger, and finally obtaining an ambient temperature value (compensated air conditioner detection temperature) used by the unit, so that the accuracy of the compensated air conditioner detection temperature can be further improved.
The correction factor may be set by experiment. Assuming that the temperature change rates of the inner tube are respectively 10 ℃/h, 15 ℃/h, 20 ℃/h and 25 ℃/h, the temperature change rate is increased more and more, so that the T is increased when the temperature change rate is 15 ℃/hAre all made ofThe temperature change rate is higher than 10 ℃/h (the temperature change rate is increased due to the increase of refrigerating capacity per hour, so that the temperature detected by an indoor unit detection device at 15 ℃/h is lower than 10 ℃/h), therefore, under the condition that the temperature of an indoor heat exchanger meets the preset condition, the compensation temperatures are different due to different temperature change rates, and therefore, the correction coefficient k is used for TSupplement deviceAnd (6) correcting.
Specifically, when the indoor heat exchanger of the air conditioner reaches a preset condition and reaches different preset durations, the actual ambient temperature values T of different temperature change rate intervals are respectively detectedRing (C)(the detection method refers to the foregoing embodiment), and at the same time, the temperature average value of the ambient temperature detected by the temperature detection device on the air conditioner indoor unit and the ambient temperature detected by the temperature detection device on the air conditioner line controller is obtained, and the corresponding compensation value determined according to the temperature average value and the actual ambient temperature value when the temperature of the indoor heat exchanger meets the preset condition for different durations is obtained. By the formula: t isRing (C)＝TAre all made of+k*TSupplement deviceAnd calculating k values in different temperature change rate intervals. Wherein, TRing (C)、TAre all made ofIs a detected value, TSupplement deviceFor a constant value, a large number ofAnd (4) obtaining correction coefficient k values corresponding to different indoor heat exchanger temperature change rate intervals through experimental detection.
According to the embodiment of the invention, the average value of the ambient temperature is obtained by combining the temperature values detected by the temperature detection device on the line controller and the temperature detection device on the internal machine, and the detected temperature of the air conditioner is compensated according to different durations of the rise or the fall of the temperature of the evaporator, so that the detected temperature of the air conditioner is closer to the actual ambient temperature, the real-time performance and the accuracy of the detected temperature of the air conditioner are effectively improved, and the user experience is further improved. And moreover, a compensation temperature correction coefficient is determined according to different intervals of the temperature change rate of the indoor heat exchanger, an ambient temperature value (compensated air conditioner detection temperature) used by the unit is finally obtained, and the accuracy of the compensated air conditioner detection temperature is further improved.
Optionally, the method may further include: and determining whether the air conditioner starts a detection temperature compensation function, and executing the steps of the method if the air conditioner starts the detection temperature compensation function.
For example, after the air conditioner is powered on, the set state value set in the memory chip is read to determine whether to perform temperature compensation. After the power is on, the function can be cancelled or started through the wire controller, and the set state is written into the memory chip so as to be used in the next power failure. Thus, the user can flexibly set whether to start the detection temperature compensation function. When the compressor is started, the detection temperature compensation logic is started.
Optionally, the method may further include: and if the compressor of the air conditioner stops exceeding the preset time, clearing the compensated air conditioner detection temperature.
Specifically, after the compressor stops exceeding the preset time t, the ambient temperature and the temperature detected by the thermal bulb are close to each other, and at this time, if the compensated air conditioner detected temperature obtained before is continuously adopted, an error may exist, so that the compensated air conditioner detected temperature obtained before is cleared, the detected temperature compensation is executed again, and the accuracy of the detected temperature compensation is improved.
Fig. 3 is a schematic structural diagram of an embodiment of a temperature compensation device for air conditioner detection provided by the present invention. As shown in fig. 3, the air conditioner detection temperature compensation apparatus 100 includes an acquisition unit 110, a determination unit 120, and a compensation unit 130.
The obtaining unit 110 is configured to obtain an average temperature value between an ambient temperature detected by a temperature detecting device on the air conditioner internal unit and an ambient temperature detected by a temperature detecting device on the air conditioner line controller; the determining unit 120 is configured to obtain a temperature of an indoor heat exchanger of the air conditioner, and determine whether compensation of a detected temperature of the air conditioner is required according to whether the temperature of the indoor heat exchanger meets a preset condition; the compensation unit 130 is configured to compensate the detected temperature of the air conditioner according to the average temperature value and the duration that the temperature of the indoor heat exchanger meets the preset condition if the determination unit 120 determines that the compensation is required.
The obtaining unit 110 obtains a temperature average value of the ambient temperature detected by the temperature detecting device on the air conditioner indoor unit and the ambient temperature detected by the temperature detecting device on the air conditioner line controller.
Specifically, after the compressor is started, the air conditioner detection temperature compensation device starts the air conditioner detection temperature compensation logic. The average temperature value may be an arithmetic average of the ambient temperature detected by the temperature detecting device on the internal machine and the ambient temperature detected by the temperature detecting device on the line controller, for example, the obtaining unit 110 reads the temperature T detected by the internal machine ambient temperature sensing bulbInner partTemperature T detected by environment temperature sensing bulb of line controllerThreadAnd obtaining the average value T of the temperatureAre all made of＝(TThread+TInner part)/2。
Preferably, the temperature average value may be a weighted average value of the ambient temperature detected by the temperature detection device on the internal unit and the ambient temperature detected by the temperature detection device on the line controller. For example, since the line controller is often placed in an area where the user is frequently active, the weight (for example, 60%) of the ambient temperature detected by the temperature detection device on the line controller may be set to be greater than the weight (for example, 40%) of the ambient temperature detected by the temperature detection device on the indoor unit. The compensated indoor environment temperature obtained by the weighted average value is more accurate and can better meet the actual requirements of users.
The determining unit 120 obtains the temperature of the indoor heat exchanger of the air conditioner, and determines whether compensation of the detected temperature of the air conditioner is required according to whether the temperature of the indoor heat exchanger meets a preset condition.
Specifically, if the temperature of the indoor heat exchanger meets a preset condition, the determining unit 120 determines that the compensation of the detected temperature of the air conditioner is required, otherwise, the determining unit 120 determines that the compensation of the detected temperature of the air conditioner is not required. The temperature of the indoor heat exchanger can be specifically the tube temperature of the indoor heat exchanger (evaporator), and can be detected through an evaporator temperature sensing bulb. The preset condition may specifically include that when the air conditioner is in a heating mode, the temperature of the indoor heat exchanger is greater than or equal to a first temperature value, and/or when the air conditioner is in a cooling mode, the temperature of the indoor heat exchanger is less than or equal to a second temperature value. That is, when the air conditioner is in a heating mode, whether the temperature C of the indoor heat exchanger is greater than or equal to a first temperature value E1 is judged, namely whether C is greater than or equal to E1, and if so, the compensation of the detected temperature of the air conditioner is determined to be needed; if not, determining that the compensation of the air conditioner detection temperature is not needed; when the air conditioner is in a refrigeration mode, judging whether the temperature C of the indoor heat exchanger is less than or equal to a second temperature value E2, namely whether C is less than or equal to E2, and if so, determining that the temperature detected by the air conditioner needs to be compensated; and if not, determining that the air conditioner detection temperature compensation is not needed.
If the determining unit 120 determines that the compensation is required, the compensating unit 130 compensates the detected temperature of the air conditioner according to the average temperature value and the duration that the temperature of the indoor heat exchanger meets the preset condition.
Fig. 4 is a schematic structural diagram of an embodiment of a compensation unit according to an embodiment of the present invention. As shown in fig. 4, in one embodiment, the compensation unit 130 includes a determination subunit 131 and a compensation subunit 132.
The determining subunit 131 is configured to determine a corresponding temperature compensation value according to a duration that the temperature of the indoor heat exchanger satisfies the preset condition.
In particular, the amount of the solvent to be used,the refrigerating capacity and the heating capacity of the air conditioner are in a direct proportion relation with the running time of the compressor, the longer the running time is, the larger the continuous refrigerating capacity and the heating capacity of the whole machine are, the needed compensation is different, therefore, different duration corresponds to different temperature compensation values, for example, when the duration reaches T1, the compensation value T isSupplement deviceY 1; the duration reaches T2, the compensation value TSupplement deviceY 2; …, respectively; the duration reaches tn, the compensation value TSupplement device＝yn。
The temperature compensation values corresponding to different durations can be preset through experiments, for example, when the temperature of the indoor heat exchanger meets the preset conditions, the environment temperature values of different indoor positions are detected, the average value of the environment temperatures of different positions is obtained and used as an actual environment temperature value T ring, or the environment temperature value of a frequent activity area of an indoor user is detected and used as an actual environment temperature value T ring, meanwhile, the temperature average value of the environment temperature detected by the temperature detection device on the indoor unit of the air conditioner and the environment temperature detected by the temperature detection device on the air conditioner wire controller is obtained, and the corresponding compensation value is determined according to the temperature average value and the actual environment temperature value when the temperature of the indoor heat exchanger meets the different durations of the preset conditions. The duration may be at least one preset duration, e.g., 1 hour, 2 hours. For example, after the duration that the indoor heat exchanger temperature satisfies C ≦ E2 reaches 1 hour, the actual ambient temperature is detected as TRing (C)35 deg.C, the temperature detected by the temperature detector on the wire controller is TThread38 ℃, the temperature detected by the temperature detection device on the inner machine is TInner part34 ℃, then: actual ambient temperature TRing (C)＝(TThread+TInner part)/2+TSupplement device，TRing (C)、TThread、TInner partFor constant value, T is obtainedSupplement deviceA value of (d); after the temperature of the indoor heat exchanger meets the condition that the duration time of E2 is less than or equal to C reaches 2 hours, detecting the actual environment temperature as TRing (C)The temperature detected by the temperature detector on the wire controller is T at 20 DEG CThreadWhen the temperature is 25 ℃, the temperature detection device on the inner machine detects the temperature as TInner partAt 18 ℃, T is also obtained from the above equationSupplement deviceA value of (d); tong (Chinese character of 'tong')T derived from different durations of the overshootSupplement deviceDifferent values are obtained, and then the temperature compensation values T corresponding to different durations are obtained through numerical statistical analysisSupplement device。
The compensation subunit 132 is configured to compensate the temperature average value according to the temperature compensation value determined by the determination subunit 131, so as to obtain a compensated air conditioner detection temperature.
In one embodiment, after the determining subunit 131 determines the corresponding temperature compensation value, the compensating subunit 132 takes the sum of the temperature compensation value and the temperature average value as the compensated air conditioner detection temperature.
For example, the determined temperature compensation value is TSupplement deviceAverage temperature value of TAre all made ofAnd the compensated air conditioner detection temperature is TRing (C)＝TAre all made of+TSupplement device. And the compensated air conditioner detection temperature is the ambient temperature value according to which the air conditioner is controlled.
In another embodiment, the temperature compensation value needs to be corrected according to different heating and cooling capacities of the compressor (such as the influence of the internal and external fans, the influence of weather changes, and the like). Specifically, the compensation subunit 132 determines a correction coefficient of the temperature compensation value according to the temperature change rate of the temperature of the indoor heat exchanger; and taking the sum of the product of the temperature compensation value and the correction coefficient and the temperature average value as the compensated air conditioner detection temperature.
The temperature change rate of the indoor heat exchanger temperature may specifically be a temperature change rate D at which the indoor heat exchanger temperature changes from T1 to T2. For example, the temperature change rate sections of different temperatures of the indoor heat exchanger may correspond to different temperature compensation value correction coefficients, and the different temperature compensation value correction coefficients corresponding to the temperature change rate sections of different temperatures of the indoor heat exchanger may be determined through experiments. For example, D ≦ N1, correction coefficient k ═ k 0; d is more than or equal to N1 and less than or equal to N2, and a correction coefficient k is k 1; d is more than or equal to N2 and less than or equal to N3, and a correction coefficient k is k 2; … …, respectively; n (m-1) is more than or equal to D and less than or equal to Nm, and a correction coefficient k is k (m-1); d is more than or equal to Nm, and the correction coefficient k is km.
For example, the determined temperature compensation value is TSupplement deviceAverage value of temperatureIs TAre all made ofAnd correcting the coefficient k, wherein the compensated air conditioner detection temperature is TRing (C)＝TAre all made of+k*TSupplement device. And determining a compensation temperature correction coefficient according to different intervals of the temperature change rate of the indoor heat exchanger, and finally obtaining an ambient temperature value (compensated air conditioner detection temperature) used by the unit, so that the accuracy of the compensated air conditioner detection temperature can be further improved.
The correction factor may be set by experiment. Assuming that the temperature change rates of the inner tube are respectively 10 ℃/h, 15 ℃/h, 20 ℃/h and 25 ℃/h, the temperature change rate is increased more and more, so that the T is increased when the temperature change rate is 15 ℃/hAre all made ofThe temperature change rate is higher than 10 ℃/h (the temperature change rate is increased due to the increase of refrigerating capacity per hour, so that the temperature detected by an indoor unit detection device at 15 ℃/h is lower than 10 ℃/h), therefore, under the condition that the temperature of an indoor heat exchanger meets the preset condition, the compensation temperatures are different due to different temperature change rates, and therefore, the correction coefficient k is used for TSupplement deviceAnd (6) correcting.
Specifically, when the indoor heat exchanger of the air conditioner reaches a preset condition and reaches different preset durations, the actual ambient temperature values T of different temperature change rate intervals are respectively detectedRing (C)(the detection method refers to the foregoing embodiment), and at the same time, the temperature average value of the ambient temperature detected by the temperature detection device on the air conditioner indoor unit and the ambient temperature detected by the temperature detection device on the air conditioner line controller is obtained, and the corresponding compensation value determined according to the temperature average value and the actual ambient temperature value when the temperature of the indoor heat exchanger meets the preset condition for different durations is obtained. By the formula: t isRing (C)＝TAre all made of+k*TSupplement deviceAnd calculating k values of different temperature change rate intervals. Wherein, TRing (C)、TAre all made ofIs a detected value, TSupplement deviceAnd if the temperature change rate is a fixed value, correction coefficient k values corresponding to different indoor heat exchanger temperature change rate intervals can be obtained through a large number of experimental detections.
According to the embodiment of the invention, the average value of the ambient temperature is obtained by combining the temperature values detected by the temperature detection device on the line controller and the temperature detection device on the internal machine, and the detected temperature of the air conditioner is compensated according to different durations of the rise or the fall of the temperature of the evaporator, so that the detected temperature of the air conditioner is closer to the actual ambient temperature, the real-time performance and the accuracy of the detected temperature of the air conditioner are effectively improved, and the user experience is further improved. And moreover, a compensation temperature correction coefficient is determined according to different intervals of the temperature change rate of the indoor heat exchanger, an ambient temperature value (compensated air conditioner detection temperature) used by the unit is finally obtained, and the accuracy of the compensated air conditioner detection temperature is further improved.
Optionally, the apparatus may further include a function determining unit (not shown) configured to determine whether the air conditioner is turned on to detect the temperature compensation function, and if it is determined that the air conditioner is turned on to detect the temperature compensation function, the apparatus performs the air conditioner detection temperature compensation.
For example, after the air conditioner is powered on, the set state value set in the memory chip is read to determine whether to perform temperature compensation. After the power is on, the function can be cancelled or started through the wire controller, and the set state is written into the memory chip so as to be used in the next power failure. Thus, the user can flexibly set whether to start the detection temperature compensation function. When the compressor is started, the detection temperature compensation logic is started.
Optionally, the apparatus may further include a clearing unit (not shown) for clearing the compensated detected temperature of the air conditioner if the compressor of the air conditioner stops for more than a preset time.
Specifically, after the compressor stops exceeding the preset time t, the ambient temperature and the temperature detected by the thermal bulb are close to each other, and at this time, if the compensated air conditioner detected temperature obtained before is continuously adopted, an error may exist, so that the compensated air conditioner detected temperature obtained before is cleared, the detected temperature compensation is executed again, and the accuracy of the detected temperature compensation is improved.
The invention also provides a storage medium corresponding to the air conditioner detection temperature compensation method, and a computer program is stored on the storage medium, and when the program is executed by a processor, the program realizes the steps of any one of the methods.
