In the accompanying drawings:

Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with embodiment and accompanying drawing, the present invention is described in further details. At this, the exemplary embodiment of the present invention and explanation thereof are used for explaining the present invention, but not as a limitation of the invention.
So that user can find the scarce fluorine situation of air-conditioning model machine in time, in order to looking for maintenance of visiting after sale to carry out adding fluorine operation in time, effectively working thus ensureing that air-conditioning can be stablized. In this example, it is provided that a kind of air conditioner coolant lacks fluorine decision method, as it is shown in figure 1, comprise the following steps:
Step 101: obtain air-conditioning and start shooting the internal ring temperature after first scheduled time and interior pipe temperature;
Step 102: obtain the evaporating pressure of described air-conditioning, wherein, evaporating pressure be cold-producing medium from liquid become gaseous state time maximum pressure;
Step 103: when evaporating pressure less than or equal to coolant lack fluorine pressure judge marginal value, and the difference between described internal ring temperature and said inner tube temperature less than or equal to the first predetermined difference value time, control described air-conditioning enter lack fluorine judgment model.
In upper example, the pressure differential of the internal ring temperature after certain time and the interior pipe temperature of being started shooting by air-conditioning, and the evaporating pressure of air-conditioning determines whether air-conditioning exists the possibility of scarce fluorine, if the pressure differential of internal ring temperature and interior pipe temperature, and the evaporating pressure of air-conditioning meets certain condition, so can specifically confirm that air-conditioning can no scarce fluorine, solve the technical problem that cannot effectively detect cold medium shortage in prior art by the way, reach whether timely and effective discovery air-conditioning lacks the purpose of fluorine, and significantly simpler to implement.
This mainly considers that the cold-producing medium of air-conditioning is when scarce fluorine, there will be the problems such as pressure decline, aerofluxus rising, if generally air-conditioning has certain time not start shooting, so in air-conditioning, the temperature of pipe and ambient temperature (i.e. internal ring temperature) are close, this time starts shooting, and interior pipe temperature can reduce at short notice, and lower than indoor environment temperature, and if coolant lacks fluorine, the difference between interior pipe temperature and internal ring temperature would not change so fast. Therefore, based on the change of pressure, and these parameters of temperature gap can effectively determine whether air-conditioning lacks fluorine.
Based on principles above, after controlling the scarce fluorine judgment model of air-conditioning entrance, can specifically determine whether according to the difference between internal ring temperature and interior pipe temperature to lack fluorine, such as, after above-mentioned steps 103, it is possible to determine that air-conditioning whether coolant lacks fluorine in such a way: statistics air-conditioning from start to internal ring temperature in second scheduled time and the difference interior pipe temperature less than or equal to the accumulated time of the second predetermined difference value; If accumulated time is more than preset time threshold, it is determined that described air conditioner coolant lacks fluorine. That is, the overlong time that internal ring temperature is less with interior pipe temperature gap, then can reflect cold medium shortage.
Because of first three minute, most inverter air conditioner needs to enter oil return, and therefore first scheduled time could be arranged to 3 minutes, and second scheduled time could be arranged to 6 minutes. That is, internal ring temperature and interior pipe temperature are divided into: 0 arrives 3min, and 0 arrives whether 6min the two interval judgement air-conditioning lacks fluorine.
After the scarce fluorine judgment model opening air-conditioning, need also exist for the frequency of air-conditioning is adjusted, in order to air-conditioning can stable operation, for instance, can enter lack after fluorine judgment model controlling air-conditioning, it is determined that whether the frequency of air-conditioning current gear is less than the frequency of most low one grade of the high tap position of current working; If it is, improve the frequency of the compressor of described air-conditioning. Concrete, it is possible to the frequency that the frequency of the compressor of air-conditioning is increased to most low one grade of the high tap position of described current working is run.
Wherein, current working may refer to the outdoor environment temperature of (when namely first scheduled time just terminated that moment) after start 3 minutes, this temperature controls in a temperature range of logic at frequency changer, also more corresponding Frequency points under this temperature range, therefore can by current frequency compared with the second of these respective frequencies points the top grade frequency.
It should be noted, however, that have only to ensure that air-conditioning is according to current working raising frequency, concrete raising frequency to which shelves can be determined according to being actually needed, and this is not construed as limiting by the application.
Further, when implementing, so that control better effects if, it can also be ensured that air-conditioning meets the following conditions:
1) before air-conditioning is started shooting, it is ensured that air-conditioning quilt places the sufficiently long time, namely ensure that indoor set pipe gentleness indoor ambient temperature gap is within 1 degree.
2) putting the available machine time and be decided to be 0min, institute is free to be calculated with the available machine time for starting;
3) consider that frequency changer running frequency is unfixed, but general single cold frequency changer needs oil return in first three minute, according to actual measurement condition, oil return frequency is all fixing, and 3 to 6 minutes different because of frequency conversion type system control parameters (memory chip parameter), specifically can in the light of actual conditions adjust the frequency state needing to bring up to 3 to 6 minutes.
Why adopt the mode that temperature and pressure judge simultaneously, the volume refrigerating capacity compressor being primarily due to coolant is big, aerofluxus is higher, if adopting merely the difference between internal ring temperature and interior pipe temperature to control, it is difficult to ensure that the state of air-conditioning (secondary refrigerant leakage situation), therefore, this parameter of evaporating pressure is introduced to combine judgement. If adopting merely pressure to judge whether to lack fluorine, owing to the pressure under each cooling condition is different, pressure changing is also not quite similar, and arranging device specially, to carry out sensed pressure variable quantity obviously relatively big to becoming present aspect increase, therefore by processing mode that difference variation auxiliary corresponding pressure value is comparatively suitable.
Illustrate below in conjunction with a specific embodiment, it is important to note, however, that this specific embodiment is merely to be better described the present invention, be not intended that inappropriate limitation of the present invention.
Determine the air-conditioning method whether coolant lacks fluorine, mainly can include the following aspects:
1) fluorine detection is lacked
The evaporating pressure P of model machine can be gatheredSteamAnd initial ring temperature T before the operating of collect and process machineRing 0With indoor pipe temperature TPipe 0. If meet following two condition simultaneously, then can trigger entrance and lack fluorine judgment model:
Condition one: model machine evaporating pressure PSteam�� refrigeration lacks fluorine pressure and judges marginal value PFace
In order to record model machine evaporating pressure, pressure transducer can be increased in refrigeration systems, for instance, it is possible to obtain 8 kgfs and carry out metrical prototype evaporating pressure, but above-mentioned 8 kilograms only be schematic description, when implementing can as desired this power number be adjusted.
Condition two: after continuous running 3min opened by compressor, the pipe temperature T that Real-time Collection arrivesPipe 0Meet TRing 0-TPipe 0�� refrigeration lacks fluorine Guan Wenhuan temperature approach, for instance, this difference can value be 1, namely ensures that Guan Wenyu room temperature is equal as far as possible.
2) after lacking the unlatching of fluorine judgment model, the frequency method of operation
If the frequency of current gear is less than the frequency of most low one grade of the high tap position of current working, then compressor frequency is increased to the frequency of most low one grade of the high tap position of current working and runs 3min, otherwise runs with the frequency of current gear.
In this is the 3 to 6th minute, it is only necessary to ensureing according to current operating mode raising frequency, being specifically increased to which shelves can adjust according to actual needs.
3), after lacking the unlatching of fluorine judgment model, fluorine determination methods is lacked
Start to count after start, terminated by the 6th minute, accumulation internal ring and interior pipe temperature approach (T in these six minutesRing 0-TPipe 1)��refrigeration lacks fluorine Guan Wenhuan temperature approach, for instance, this difference can value be that the time of 2 was more than 3 minutes, it is possible to judges to lack fluorine.
After mass data is tested, it is found that this determine that the method for scarce fluorine is very accurate.
4) specific condition whether fluorine pattern opens is lacked:
When groundwater increment is higher than more than 70%, do not allow access into scarce fluorine pattern; When groundwater increment is lower than less than 30%, it is necessary to enter and lack fluorine pattern.
In this example, the evaporating pressure P of air-conditioningSteamThe very low operating mode of a lot of secondary refrigerant leakage (such as: groundwater increment is more than more than 70%) can be screened out when being initially powered up judging, so can ensure that air-conditioning does not have protection by mistake. After the air-conditioning that a part of secondary refrigerant leakage degree is less is fallen in pressure change screening, the test prototype of 97% can being made to perform according to scarce fluorine pattern unlocking condition again through interior pipe, two interval judgement of internal ring temperature approach (0 to 3min, 0 to 6min), accuracy is better. And first three minute needs to consider to enter oil return because of most of frequency changers, if therefore fixing measurement condition, the model machine operational factor such as oil return frequency all determines, and therefore can ensure that the relative uniformity of program.
In this example, only gathering the data that air-conditioning is started shooting first 6 minutes, according to testing confirmation at present, occur that the aspect situations such as aerofluxus frequency reducing to be started shooting after more than 6 minutes at least, temperature just can reach aerofluxus protection temperature.
By the way, effectively determine whether air-conditioning lacks fluorine, thus improve the stability of operation of air conditioner, not havinging and disorderly shutting down phenomenon, and user can be allowed to find in time to lack fluorine situation, in order to notify that personnel carry out adding fluorine maintenance after sale.
