Description
Technical Field
The invention relates to a method for detecting and correcting the outer ring temperature of a variable frequency air conditioner.
Background
With the continuous development of daily household appliance technology, more and more household appliances enter the daily life and work of people, but due to different specific application environments and conditions, the household appliances have a plurality of corresponding problems in the application process. Taking a frequency conversion air conditioner as an example, an outdoor ambient temperature sensor of the existing frequency conversion split type air conditioner is generally arranged on a condenser, and the sensor is easily influenced by heat radiation of the condenser in a refrigeration mode because the sensor is closely spaced from the condenser. Especially, under the working condition that the outdoor environment temperature is high, the influence is very obvious, and the outdoor environment temperature detected by the sensor is far higher than the actual outdoor environment temperature.
For the inverter air conditioner, in order to ensure the safe operation of the compressor and avoid the compressor from being burnt out in a high-temperature environment, the inverter air conditioner can adjust the maximum allowable operation frequency of the compressor according to the outdoor environment temperature detected by the sensor within a certain temperature range; specifically, in a certain temperature range, as the outdoor environment temperature acquired by the inverter air conditioner from the sensor increases, the maximum frequency at which the compressor is allowed to operate decreases. In the cooling mode, the problem that the outdoor environment temperature detected by the sensor is higher than the actual outdoor environment temperature exists, so that the accuracy of the adjustment of the highest frequency allowed by the air conditioner to the compressor is influenced, the reduction range of the operation frequency of the compressor is overlarge, and the cooling effect is influenced.
Therefore, in the cooling mode, in order to solve the problem that the outdoor environment temperature detected by the sensor is higher than the actual outdoor environment temperature, and avoid the situation that the maximum frequency of the allowed operation of the compressor is excessively adjusted by the air conditioner, which causes the operation frequency of the compressor to be excessively reduced, and ensure the cooling effect of the air conditioner, a method for correcting the outdoor environment temperature detected by the sensor needs to be provided.

However, the number of parameters involved in the application is large, the temperature correction method is complex, and in the same region, although the same weather information is provided, the ambient temperature around the air conditioner outdoor unit has a large difference due to different installation positions of the air conditioner outdoor unit, which undoubtedly has a certain influence on the temperature correction process and reduces the accuracy of temperature correction.

Detailed Description
The technical solutions in the embodiments of the present invention are further described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
When the air conditioner is not started, the outdoor environment temperature sensor of the air conditioner and the environment temperature value of the coil temperature sensor in the middle of the condenser are close to each other, and the numerical values are approximate to the outdoor real environment temperature value. After refrigeration and startup, due to the fact that a refrigerant circulates and releases heat when passing through the condenser, the temperature detected by the coil temperature sensor in the middle of the condenser can quickly rise in a short time and then is stable, the temperature detected by the outdoor environment temperature sensor is the same as the temperature value when the condenser is started, but the detected temperature is easily affected by heat radiation of the condenser due to the fact that the position where the outdoor environment temperature sensor is installed is close to the condenser, the detected outdoor environment temperature is larger than the environment temperature when the condenser is started, and poor air conditioner refrigeration effect is caused in order to avoid the situation that the highest frequency of allowed operation of the compressor is reduced due to overhigh outdoor environment temperature detected by the air conditioner, and therefore the outdoor environment temperature detected by the air conditioner needs to be corrected.
Example 1
As shown in fig. 1, a method for detecting and correcting the outer ring temperature of an inverter air conditioner includes:
s1, starting the air conditioner and operating in a refrigeration mode;
s2, detecting the outdoor environment temperature T10 and the condenser middle coil temperature T20 when the air conditioner is started, judging whether a correction starting condition is met, if so, performing the step S3, and if not, not correcting the outdoor environment temperature T1;
s3, after the air conditioner continuously operates for a first rated time T1, detecting the outdoor environment temperature T11 in real time;
s4, judging whether the second rated temperature difference B is used as a reference, and if so, correcting the T1, wherein the T11-T10 is not less than B; if not, T1 is not corrected.
In the embodiment, the air conditioner detects the outdoor environment temperature T10 and the condenser middle coil temperature T20 when the air conditioner is started, judges whether T10 and T20 meet the correction starting condition or not, and starts the temperature correction process when the correction conditions are met, so that the error correction condition of the air conditioner caused by the interference of factors such as the use environment or air conditioner faults can be effectively avoided, and the accuracy and the reliability of temperature correction are improved.
When the air conditioner is used for temperature correction, the air conditioner is continuously operated for a preset time period, after the air conditioner is ensured to be in a stable operation state, the outdoor environment temperature T11 is monitored in real time, whether the temperature T11-T10 reaches a preset temperature difference is judged, if the temperature T11-T10 does not reach the preset temperature difference, the detected outdoor environment temperature of the air conditioner is approximate to the environment temperature (namely the actual environment temperature value) when the air conditioner is started, the air conditioner has small influence on the air conditioning effect, and the temperature can not be corrected; if the temperature reaches the preset temperature, the detected outdoor environment temperature of the air conditioner is far higher than the environment temperature when the air conditioner is started, and the temperature must be corrected, so that the situation that the maximum frequency of the allowed operation of the compressor is reduced due to the overhigh outdoor environment temperature detected by the air conditioner, and the refrigeration effect of the air conditioner is poor is avoided.
To further explain the temperature correction process, the air conditioner monitors the outdoor ambient temperature T11 in real time, and when temperature correction is performed, the air conditioner uses T11-B as the outdoor ambient temperature, and when temperature correction is not performed, the air conditioner uses T11 as the outdoor ambient temperature.
Example 2
As shown in fig. 2, a method for detecting and correcting the outer ring temperature of an inverter air conditioner includes:
s1, starting the air conditioner and operating in a refrigeration mode;
s2, detecting the outdoor environment temperature T10 and the temperature T20 of the middle coil of the condenser when the air conditioner is started;
s3, based on the rated lower limit temperature T3 and the rated upper limit temperature T4, judging whether T3 is more than or equal to T10 and more than or equal to T4 are met, if yes, performing step S4, and if not, not correcting T1;
s4, judging whether a first rated temperature difference A is satisfied or not and is not more than T10-T20A, if so, performing S5, and if not, not correcting T1;
s5, after the air conditioner continuously operates for a first rated time T1, detecting the outdoor environment temperature T11 in real time;
s6, judging whether the second rated temperature difference B is used as a reference, and if so, correcting the T1, wherein the T11-T10 is not less than B; if not, T1 is not corrected.
The method of the embodiment is based on embodiment 1, the determination of whether the air conditioner meets the correction starting condition is determined by setting two continuous determination processes, specifically, the air conditioner firstly determines whether the air conditioner meets T3 or not and T10 or not and T4 or not, and determines whether the air conditioner is started or not according to the working environment temperature of the air conditioner, because the working environment temperature of the air conditioner is low, the refrigeration effect is always in a good state, the temperature correction is not needed, and when the working environment temperature is high, the air conditioner can perform self-protection; therefore, the judgment process avoids the interference of the working environment of the air conditioner on the temperature correction starting process, avoids the error correction of the air conditioner, and improves the accuracy of the temperature correction starting of the air conditioner;
then, when the air conditioner is started, the outdoor environment temperature sensor of the air conditioner and the environment temperature value measured by the coil pipe temperature sensor in the middle of the condenser are close to each other, so that the air conditioner determines whether the outdoor environment temperature sensor of the air conditioner is in a fault state or not by judging whether T10-T20I is not more than A or not on the basis of judging whether T3 is not more than T10 is not more than T4 or not, if so, the outdoor environment temperature sensor of the air conditioner is normal, so that the temperature correction process can be started, and if not, the outdoor environment temperature sensor of the air conditioner is in the fault state, the temperature is not corrected, so that the error correction condition is avoided; therefore, the judgment process eliminates the interference of the temperature sensor fault on the temperature correction starting process, avoids the error correction of the air conditioner, improves the accuracy of the temperature correction starting of the air conditioner, and simultaneously ensures the accuracy and the reliability of the temperature detection in the temperature correction process.
In this embodiment, since the steps S3 and S4 are two consecutive determination processes for determining whether the air conditioner satisfies the correction start condition, and the two logic determinations in the steps S3 and S4 do not succeed each other, a modification is made on the basis of the method of this embodiment, as shown in fig. 3, the present embodiment provides another method for detecting and correcting the outer loop temperature of the inverter air conditioner, including:
s1, starting the air conditioner and operating in a refrigeration mode;
s2, detecting the outdoor environment temperature T10 and the temperature T20 of the middle coil of the condenser when the air conditioner is started;
s3, judging whether a first rated temperature difference A is satisfied or not and is not more than T10-T20A, if so, performing S4, and if not, not correcting T1;
s4, based on the rated lower limit temperature T3 and the rated upper limit temperature T4, judging whether T3 is more than or equal to T10 and more than or equal to T4 are met, if yes, performing step S5, and if not, not correcting T1;
s5, after the air conditioner continuously operates for a first rated time T1, detecting the outdoor environment temperature T11 in real time;
s6, judging whether the second rated temperature difference B is used as a reference, and if so, correcting the T1, wherein the T11-T10 is not less than B; if not, T1 is not corrected.

m1, correcting the outdoor environment temperature T1 by the air conditioner;
m2, judging whether the artificial conditions are met by the air conditioner, if so, quitting the correction, and if not, performing the step M3;
m3, during the second rated time T2, the air conditioner continuously detects T1;
m4, based on the rated lower limit temperature T3, judging whether T1 < T3 is satisfied, if so, exiting the correction, if not, returning to the step M2.
The artificial condition comprises at least one judgment condition of whether to shut down or not and whether to switch modes.
In this embodiment, after the temperature correction of the air conditioner, when there is an off state of the air conditioner, a mode switching of the air conditioner, or when T1 < T3 is caused by an actual outdoor temperature drop, the temperature correction is exited, and the outdoor environment temperature needs to be detected and corrected again after the next on state after the exiting.
