Conjunction is not present, also not within the protection domain of application claims.
The present invention proposes a kind of detection method of compressor temperature sensor.
In the first embodiment of the present invention, as shown in figure 1, the detection method of the compressor temperature sensor is including following
Step：
Step S100, the running frequency of compressor is changed according to parameter preset in the first preset period of time；
Wherein, the first preset period of time generally selects the period that compressor has been in after steady operational status, specifically, right
For compressor in air conditioner, selection has stably reached the period of design temperature when indoor temperature, for refrigerator, refrigerator-freezer
For compressor in, actual temperature is selected to reach the period of the cryogenic temperature of setting, to exclude other factors to row
The interference of temperature degree, improve the accuracy of the detection to temperature sensor.When changing the running frequency of compressor, generally according to pre-
If compressor frequency is raised and lowered in rule in proper range, it should be noted that the excursion of compressor operating frequency
The mid frequency range being preferably between compressor minimum operating frequency and maximum running frequency, so as to avoid compressor from transporting
Row avoids because compressor state labile causes the inaccuracy to temperature sensor detection, also simultaneously under extremity
The service life of compressor can be extended.
Step S200, the delivery temperature of the compressor of temperature sensor detection in the second preset period of time is obtained；
Because the circulation of refrigerant needs certain time, also there is certain hysteresis plus detection of the temperature sensor to temperature
Property, therefore, change of the delivery temperature compared to compressor operating frequency for the compressor that temperature sensor detects has necessarily
Hysteresis quality.Second preset period of time of detection delivery temperature and the first preset period of time of compressor operating frequency change might not be complete
It is complete consistent.In a specific example, the second preset period of time and the first preset period of time coincide, but should be noted the stagnant of temperature change
Property afterwards.In another specific example, the second preset period of time covers the first preset period of time, to observe complete temperature change feelings
Condition.Certainly, in another specific example, the second preset period of time suitably lags behind the first preset period of time, so as in complete detection row
While gas temperature variations, detection duration is reduced, detection efficiency is improved, hereinafter also will be apparent from.
Step S300, judge whether delivery temperature is corresponding with the running frequency of compressor；
If so, perform step S410, judge that temperature sensor is normal；
If it is not, perform step S420, judge abnormality of temperature sensors.
In refrigerant circulation circuit, with the increase of compressor operating frequency, the gas flow of compression increases in the unit interval,
Accordingly, delivery temperature raises, by judging whether delivery temperature is corresponding with the running frequency of compressor, specifically, including
Whether the parameters such as the variation tendency of delivery temperature, detected value, rate of change are corresponding with the running frequency of compressor, it can be determined that temperature
Whether degree sensor is in normal condition.When delivery temperature is corresponding with the running frequency of compressor, temperature sensor is normal,
Otherwise, abnormality of temperature sensors.
In the present embodiment, the detection method of compressor temperature sensor comprises the following steps：In the first preset period of time
Change the running frequency of compressor according to parameter preset；Obtain the row of the compressor that temperature sensor detects in the second preset period of time
Temperature degree；Judge whether delivery temperature is corresponding with the running frequency of compressor；If so, judge that temperature sensor is normal；If it is not,
Judge abnormality of temperature sensors.In the refrigerant circulation circuit of electric equipment, the delivery temperature of compressor is in its running frequency
Positive correlation.In the case where other operational factors of compressor are constant, with the increase of running frequency, unit interval internal pressure
The gas of contracting increases, accordingly, delivery temperature rise.By changing the running frequency of compressor, judge that temperature sensor detects
Whether obtained delivery temperature is corresponding with the change of running frequency, to judge whether temperature sensor is normal.Due to compressor
Running frequency can easily be regulated and controled by default program etc., therefore, in the inventive solutions, without by temperature
Degree sensor takes apart from compressor, you can the delivery temperature detected according to it judges whether to be in normal condition, greatly
The big detection difficulty for simplifying temperature sensor, makes the detection of compressor temperature sensor very succinctly facilitate, and then is easy to pair
The running status of electric equipment is monitored, and is advantageous to improve the reliability of electric equipment.
In the second embodiment of the present invention, as shown in Fig. 2 before step S100, the inspection of compressor temperature sensor
Survey method is further comprising the steps of：
Step S500, compressor is controlled to be run in the 3rd preset period of time with the frequency of the first preset period of time initial time.
In the present embodiment, before controlling compressor operating frequency change, first compressor is controlled to be run with a setpoint frequency
Set duration.Wherein, the setpoint frequency is equal with the frequency of the first preset period of time initial time, that is to say, that is compressed in control
Before machine running frequency changes, compressor is in steady operational status, and delivery temperature is done so as to eliminate other factorses
Disturb, be advantageous to improve the degree of accuracy judged.
In the third embodiment of the present invention, as shown in figure 3, electric equipment includes control valve, control valve and compressor phase
Connection, step S100 include：
Step S110, the running frequency of compressor is controlled to be increased to the by the first predeterminated frequency in the second default sub-period
Two predeterminated frequencies；
Step S120, control compressor is run with the second predeterminated frequency in the 3rd default sub-period；
Step S130, the running frequency of compressor is controlled to be reduced to the by the second predeterminated frequency in the 4th default sub-period
Three predeterminated frequencies.
During step S100 is performed, constant opening degree of the control valve in the first preset period of time, so as to eliminate because
The change of control valve opening causes gas flow in compressor to change, the change of delivery temperature caused by entering.Wherein, first is pre-
If the period is made up of the second default sub-period, the 3rd default sub-period and the 4th default sub-period.It is that is, default second
In sub-period, the frequency of compressor is controlled first to be increased to the second predeterminated frequency by the first predeterminated frequency, in the 3rd default sub-period
It is interior, the second predeterminated frequency is maintained, the running status of compressor is tended towards stability, on the other hand avoids frequently change compression
Unit frequency and reduce its life-span, and then control compressor frequency the 3rd predeterminated frequency is reduced to by the second predeterminated frequency.
In above-mentioned changes phase, compressor operating frequency has ascent stage and decline stage, and accordingly, delivery temperature has rise and drop
It is low, it is whether normal so as to comprehensively detection temperature sensor.
Further, in the fourth embodiment of the present invention, step S200 includes：
Step S210, judge in the 5th default sub-period, whether delivery temperature by the first temperature range rises to the second temperature
Spend scope；
Step S220, judge in the 6th default sub-period, whether delivery temperature by second temperature scope drops to the 3rd temperature
Spend scope.
Wherein, for the sake of easy, choose the second preset period of time and coincided with the first preset period of time, the second preset period of time is by the 5th
Default sub-period and the 6th default sub-period composition, the duration of the 5th default sub-period are more than the duration of the second default sub-period,
And duration and the duration sum of the 3rd default sub-period less than the second default sub-period, at this stage, the fortune of compressor
Line frequency takes the lead in rising keeps constant again, it is contemplated that the hysteresis quality of hysteresis quality and the temperature sensor detection of refrigerant circulation, accordingly,
The delivery temperature that temperature sensor detects should rise to second temperature scope by the first temperature range, afterwards, the fortune of compressor
Line frequency is begun to decline, and accordingly, delivery temperature should be dropped to the 3rd temperature range by second temperature scope.In the present embodiment
In, not only judge the rate of change of delivery temperature, and the detected value of delivery temperature is judged, to determine the TEMP
Whether device is in normal condition.
For example, the changing value of one group of delivery temperature and the changing value relation such as following table of compressor operating frequency,
| The changing value Δ f (Hz) of compressor operating frequency | The changing value Δ T (DEG C) of delivery temperature |
| -18 | -6 |
| -15 | -5 |
| -12 | -4 |
| -10 | -3 |
| -8 | -2 |
| 8 | 3 |
| 10 | 4 |
| 12 | 5 |
| 15 | 6 |
| 18 | 7 |
When the frequency rise of compressor, the changing value Δ f of compressor operating frequency and the changing value Δ T of delivery temperature it
Between fit correlation it is as follows：Δ T=-0.0137 Δs f2+0.7519Δf-2.2；When the frequency of compressor reduces, compressor fortune
Fit correlation between the changing value Δ f of line frequency and the changing value Δ T of delivery temperature is as follows：Δ T=-0.0137 Δs f2+
0.7519Δf+3.2.Under identical condition, when judging whether temperature sensor is normal, can be determined according to above-mentioned fit correlation
Second temperature scope and the 3rd temperature range.
In the fifth embodiment of the present invention, as shown in figure 5, step S200 also includes：
Step S230, the duration between judging at the time of initial time to the delivery temperature of the second preset period of time is begun to ramp up
Whether it is more than the first preset duration, and is less than the second preset duration.
Wherein, the first preset duration is less than the duration of the 5th default sub-period.In the present embodiment, it is contemplated that detect
The hysteresis quality of delivery temperature, by obtaining specific hysteresis duration, whether the susceptibility of temperature sensor is normal.Wherein,
First preset duration is to determine temperature sensor susceptibility normal most short lag time, and the second preset duration is to determine temperature
Sensor sensitivity normal most long lag time.When initial time to the delivery temperature of the second preset period of time is begun to ramp up
When duration between quarter is between the first preset duration and the second preset duration, show that the hysteresis of temperature sensor is normal, it is no
Then, temperature sensor there may be failure.The order of determination is had no between step S230 and step S210, step S220, can be
Get after the delivery temperature that temperature sensor detects while judge, can also real-time judge, now, step S230 is positioned at step

In the present embodiment, the first predeterminated frequency is equal to the 3rd predeterminated frequency, after compressor operating is stable, two states
Under delivery temperature between difference should be smaller.Therefore, the exhaust temperature measured by detecting the initial time of the second preset period of time
Degree and the poor absolute value of the delivery temperature measured in the end time of the second preset period of time, can determine whether the hysteresis of temperature sensor
Property and measurement it is offset resistance.When above-mentioned poor absolute value is less than or equal to fiducial temperature, show that the detection of temperature sensor is stagnant
Smaller afterwards, and the offset of detected value is small, otherwise, the hysteresis quality of temperature sensor and offset resistance all more serious may shadow
Ring the normal operation to electric equipment.The order of determination is had no between step S240 and step S210, step S220, can obtained
After the delivery temperature detected to temperature sensor while judge, can also real-time judge, now, step S240 is located at step
