On the one hand, the embodiment of the present invention provides a kind of retaining valve leakage detection method, is applied to air-conditioning, please refer to Fig. 1, specifically comprises:
Step S101: during in the first operational mode, detect and obtain the first temperature value of retaining valve first end and detect the second temperature value that obtains retaining valve the second end at air-conditioning;
Step S102: the absolute value of determining the difference of the first temperature value and the second temperature value;
Step S103: judge whether absolute value is greater than predetermined threshold value;
Step S104: in the time that absolute value is greater than predetermined threshold value, determine that leaking appears in retaining valve.
In step S101, the first operational mode is for example heating mode.
In step S101, can detect in several ways and obtain the first temperature value and the second temperature value, two kinds that enumerate below are wherein introduced, and certainly, in specific implementation process, are not limited to following two kinds of situations.
The first, be provided with the first temperature sensor at first end, detect and obtain the first temperature value by the first temperature sensor, at the second end, the second temperature sensor is set, detect and obtain the second temperature value by the second temperature sensor, in this case, because the first temperature sensor is attached to first end, the second temperature sensor is attached to the second end, so have the first detected temperature value and the more accurate technique effect of the second temperature value.
The second, on air-conditioning, be only provided with a temperature sensor, for example: infrared temperature sensor, then send the infrared signal of different directions by infrared temperature sensor, and then detection obtains the first temperature value and the second temperature value respectively, due in this case, only a temperature sensor need to be set, so there is the technique effect reducing costs.
In specific implementation process, in step S101, can detect and obtain the first temperature value and the second temperature value by multiple trigger condition, enumerate two kinds of trigger conditions wherein below, certainly, in specific implementation process, be not limited to following two kinds of trigger conditions.
Detect and obtain the first temperature value of retaining valve first end and detect the second temperature value that obtains retaining valve the second end, be specially:
Every Preset Time interval, detect and obtain the first temperature value and the second temperature value.
Preset Time interval is for example: 30min, 1h, 2h etc., this embodiment of the present invention is not restricted, one timer can be set in air-conditioning inside, every Preset Time interval, timer just produces a pulse signal, air-conditioning, after this pulse signal being detected, just detects and obtains the first temperature value and the second temperature value, and then determine by the first temperature value and the second temperature value whether retaining valve breaks down.Can ensure in time whether retaining valve is leaked and detected by such scheme.
The second, please refer to Fig. 2, detects and obtains the first temperature value of retaining valve first end and detect the second temperature value that obtains retaining valve the second end, is specially:
Step S201: detect the exhaust pressure value that obtains air-conditioning;
Step S202: judge whether exhaust pressure value is less than preset pressure value;
Step S203: in the time that exhaust pressure value is less than predetermined threshold value, detects and obtain the first temperature value and the second temperature value.
In step S201, the exhaust pressure value of air-conditioning refers to air through the pressure size at gas outlet place after compressor compresses, can pressure transducer be set at gas outlet place, for example: resistance pressure transmitter, capacitance pressure transducer, etc., then detect and obtain the exhaust pressure value of air-conditioning under the first mode of operation by pressure transducer, being for example 1.2MPa, can certainly be other value, such as: 1.7MPa, 2.0MPa etc.
In step S202, preset pressure value can for air-conditioning dispatch from the factory before arrange preset pressure value, also can different preset pressure values be set for each air-conditioning, this embodiment of the present invention is not restricted, suppose that preset pressure value is 1.5MPa, can determine so exhaust pressure value and be less than preset pressure value.
In step S203, under normal circumstances, under heating mode, if exhaust pressure value is less than preset pressure value, may there is at least one situation in following several situation:
1. the four-way change-over valve internal leakage of air-conditioning;
2. the retaining valve of air-conditioning leaks;
3. the refrigeration system of air-conditioning lacks fluorine;
4. the exhaust efficiency of the compressor of air-conditioning declines;
5. indoor environment temperature is too low.
As can be seen here, be less than predetermined threshold value at the exhaust pressure value of air-conditioning, may cause because retaining valve leaks, so in this case, just detect the first temperature value and the second temperature value, to determine whether retaining valve leaks, thereby can prevent from frequently detecting the first temperature value and the second temperature value, and then can reduce the processing load of air-conditioning.
In step S102, suppose that the first temperature value is 20 DEG C, the second temperature value is 25 DEG C, the difference of the first temperature value and the second temperature value is-5 DEG C so, take absolute value is 5 DEG C, certain the first temperature value and the second temperature value can also, for other value, no longer itemize and not be restricted this embodiment of the present invention.
In step S103, predetermined threshold value is for example: 1 DEG C, 2 DEG C, so the absolute value of the difference of the first temperature value and the second temperature value is greater than predetermined threshold value, the first temperature value and the second temperature value differ larger as can be seen here.
In step S104, if the first temperature value and the second temperature value difference are larger, illustrate that leaking appears in retaining valve, need to carry out inspection and maintenance to retaining valve.
Further, if absolute value is less than predetermined threshold value, illustrate that the first temperature value and the second temperature value differ less, so in this case, illustrate that retaining valve does not break down.
As further preferred embodiment, in the time that absolute value is greater than predetermined threshold value, method also comprises:
Produce information, information is used for pointing out retaining valve to occur leaking.
