Air-conditioning, which is in, lacks fluorine state.
Above-mentioned scheme can be performed simultaneously, and one can also be selected according to actual conditions, selects the execution of two selectivity, as long as according with
The decision condition of any of which scheme to be closed, judges that air-conditioning is in and lacks fluorine state, now, it is preferable that system, which is shown, lacks fluorine operation,
Fault-signal, or a series of safeguard measures such as triggering control shutdown can be triggered.It is above-mentioned that embodiments, provides a variety of systems
The determination strategy of lack of fluorine of air-conditioners under chill formula, meet that any Rule of judgment triggers the cue of scarce fluorine operation so that making
Fluorine prompting is lacked under cold state becomes more accurate.
In yet another embodiment of the present invention, additionally provide when the operational mode information of air-conditioning is heating mode
It is preferred that control strategy, during specific implementation, as shown in figure 3, when the operational mode information of current air-conditioning is heating mode, call with
Judge that process judges that air-conditioning whether in fluorine state is lacked, can use such as corresponding to the operational mode information of the current air-conditioning obtained
Lower scheme：
Scheme one：First is called to judge that whether process judges air-conditioning in scarce fluorine state, wherein, first judges process detection
Air-conditioning continuous operating time, and judge air-conditioning whether in scarce fluorine state according to continuous operating time.During specific implementation, first sentences
Disconnected process judges that air-conditioning is in and lacks fluorine state when detecting that air-conditioning continuous operating time meets the first preset time A3.With/
Or,
Scheme two, second is called to judge that whether process judges air-conditioning in scarce fluorine state, wherein, second judges process detection

The decision condition of any of which scheme to be closed, judges that air-conditioning is in and lacks fluorine state, now, it is preferable that system, which is shown, lacks fluorine operation,
Fault-signal, or a series of safeguard measures such as triggering control shutdown can be triggered.
In air-conditioning in actual use, air-conditioning system enters refrigeration mode, if system lacks fluorine and can cause cooling system
Ability substantially reduces, and inner side heat exchange deficiency, inner tube temperature and interior environment difference variation are smaller, so being capable of the whether scarce fluorine of effective detection
Operation, if but system in summer normal operation, the leakage refrigerant time is autumn and winter, can not effective detection into heating mode
Whether fluorine operation is lacked.It is above-mentioned embodiments, provides the determination strategy of lack of fluorine of air-conditioners under a variety of heating modes, when system is entered
After entering heating mode, because now outside be evaporation side, if system lacks fluorine, similarly outer tube temperature and external environment difference variation compared with
It is small.Simultaneously larger in view of outer fan delivery, heat exchange is relatively strong, it is necessary to interior machine heat exchange situation be taken into account, if system lacks fluorine and can cause inner side
Just fully exchanged heat when air-supply enters evaporator half, later half heat exchange is smaller, and inner tube medium temperature approaches with leaving air temp, and system
When lacking fluorine heating, interior liquid pipe temperature approaches with interior leaving air temp, can use leaving air temp in interior liquid pipe temperature replacement.Judged
When, meet that any Rule of judgment triggers the cue of scarce fluorine operation so that fluorine prompting is lacked under heating state to be become more
Accurately.Meanwhile the scarce fluorine under the detection of scarce fluorine and refrigeration mode of air-conditioning under heating mode is detected and adopted according to operation of air conditioner principle
With each different control strategies so that the entirety of air-conditioning system, which lacks fluorine prompting, becomes more accurate.
On the device in above-described embodiment, wherein unit, module performs the concrete mode of operation relevant
It is described in detail in the embodiment 1 of this method, explanation will be not set forth in detail herein.
