Description
Technical field
The present invention relates to air-conditioning technical field, more particularly to a kind of air conditioner.
Background technology
With the rising of Global Temperature, air conditioner comes into huge numbers of families, is more and more used.Through market survey
It was found that, occur often because air-conditioning refrigerant leaks the situation that causes machine and can not normally run, on the one hand influence consumer is to production
The satisfaction that product are used, on the other hand, because refrigerant R22 has destruction to the ozone in atmosphere, should more reduce refrigeration
Agent is leaked into air.
Cause the reason for refrigerant is leaked a lot, for detachable air conditioner, heat exchange manifold weld and interior
The presence of microminiature leakage is easier at outer machine connecting line, current air conditioner shuts down after operation, compressor stops fortune
Turn, refrigerant is dispersed in indoor external heat exchanger and corresponding pipeline, because internal pressure is higher than external ambient atmosphere pressure, hold very much
Refrigerant is easily caused slowly to be lost in by microminiature leak.
In summary, the problem of refrigerant in the heat exchanger and respective line of air conditioner is leaked how is solved, it has also become
Those skilled in the art's technical barrier urgently to be resolved hurrily.
The content of the invention
It is an object of the invention to provide a kind of air conditioner, the refrigerant in heat exchanger and respective line to avoid air conditioner
Leakage.
To achieve these goals, the invention provides a kind of air conditioner, including compressor, condenser and evaporator, institute
The gas exhaust piping for stating compressor is connected with the condenser, and the return line of the compressor is connected with the evaporator, described
It is provided with gas exhaust piping in the first stop valve, the return line and is provided with the second stop valve；
When the compressor is opened, first stop valve and second stop valve are in conducting state；
When the compressor just stops operating, first stop valve can be closed immediately, second stop valve
It can tend to remain on to preset time and turn off.
Preferably, the preset time is 20 seconds.
Preferably, first stop valve is magnetic valve.
Preferably, second stop valve is magnetic valve.
Preferably, second stop valve is tended to remain on to preset time by connecting time-delay relay and turned off.
Content is introduced compared to background technology, above-mentioned air conditioner, by setting the first stop valve and the second stop valve, makes sky
When adjusting the device to shut down, namely when compressor just stops, gas exhaust piping instantaneously still in high pressure, return line still in low pressure,
Although now the first stop valve is closed, the flowing of the fluid in pipeline continues flowing due to inertia, and then makes
Refrigerant-recovery in heat exchanger system to inside compressor；After preset time is flowed to, the second stop valve is closed, from
And cause the channel interior formation negative pressure between the first stop valve and the second stop valve, even if also in heat exchanger and system pipeline
Pressure is less than external environment condition standard atmospheric pressure, when system has minute leakage point, it is to avoid the slow leakage of refrigerant.
Brief description of the drawings
Fig. 1 is the theory structure schematic diagram of air conditioner provided in an embodiment of the present invention.
In figure 1 above, arrow represents the flow direction of fluid：
Compressor 1, condenser 2, evaporator 3, gas exhaust piping 4, return line 5, the first stop valve 6, the second stop valve 7,
Throttling arrangement 8.
Embodiment
The core of the present invention is to provide a kind of air conditioner, the refrigerant in heat exchanger and respective line to avoid air conditioner
Leakage.
In order that those skilled in the art more fully understands the technical scheme that provides of the present invention, below in conjunction with accompanying drawing and
The present invention is described in further detail for specific embodiment.
As shown in figure 1, air conditioner provided in an embodiment of the present invention, including compressor 1, condenser 2 and evaporator 3, compression
The gas exhaust piping 4 of machine 1 is connected with condenser 2, and the return line 5 of compressor 1 is connected with evaporator 3, is provided with gas exhaust piping 4
The second stop valve 7 is provided with first stop valve 6, return line 5；When compressor 1 is opened, the first stop valve 6 and second section
Only 7 valves are in conducting state；When compressor 1 just stops operating, the first stop valve 6 can be closed immediately, the second cut-off
Valve 7 can be tended to remain on to preset time and turned off.Explanation is needed exist for, those skilled in the art should be able to
What is understood is the heat exchanger system of air-conditioning, typically should also have throttling arrangement 8, and the throttling arrangement 8 is arranged on condensation
Between device 2 and evaporator 3.
Content is introduced compared to background technology, above-mentioned air conditioner, by setting the first stop valve and the second stop valve, makes sky
When adjusting the device to shut down, namely when compressor just stops, gas exhaust piping instantaneously still in high pressure, return line still in low pressure,
Although now the first stop valve is closed, the flowing of the fluid in pipeline continues flowing due to inertia, and then makes
Refrigerant-recovery in heat exchanger system to inside compressor；After preset time is flowed to, the second stop valve is closed, from
And cause the channel interior formation negative pressure between the first stop valve and the second stop valve, even if also in heat exchanger and system pipeline
Pressure is less than external environment condition standard atmospheric pressure, when system has minute leakage point, it is to avoid the slow leakage of refrigerant.
In some specific embodiments, the corresponding preset time of time-delay closing of above-mentioned second stop valve is 20 seconds.
Of course, it should be understood that being only within above-mentioned 20 seconds the preferable examples of the embodiment of the present invention, it can also be according to air conditioner correspondence
Heat exchanger built-in system facilities selection other times value.
In addition, one or two in the above-mentioned stop valve 7 of first stop valve 6 and second can be magnetic valve.By setting
, can be with the opening and closing of the on-off control valve body of the power supply of application valve body, simpler convenience into magnetic valve.Can certainly
Be above-mentioned magnetic valve be only the embodiment of the present invention preferable examples or mechanical valve body.
In addition, when the second stop valve 7 is magnetic valve, can be tended to remain on by connecting time-delay relay to default
Time turns off.Of course, it should be understood that above-mentioned time-delay relay realizes that the second stop valve time-delay closing is only the present invention
Other time-delay closing devices that the preferable examples of embodiment or those skilled in the art commonly use are realized, such as are directly led to
Cross controller and control the second stop valve time-delay closing.
