Description
Technical field
It the utility model is related 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 because air-conditioning refrigerant leakage cause machine can not the situation of normal operation occur often, on the one hand influence consumer to production
The satisfaction that product use, on the other hand, because refrigerant R22 has destruction to the ozone in atmosphere, it should more reduce refrigeration
Agent is leaked into air.
The reason for causing refrigerant to leak, is a lot, for detachable air conditioner, heat exchange manifold weld and interior
The presence of microminiature leakage is easier at outer machine connecting line, air conditioner shuts down after operation at present, and 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, is held very much
Refrigerant is easily caused slowly to be lost in by microminiature leak.
In summary, how to solve the problems, such as the refrigerant leakage in the heat exchanger of air conditioner and respective line, it has also become
Those skilled in the art's technical barrier urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to provide a kind of air conditioner, to avoid the system in the heat exchanger of air conditioner and respective line
Cryogen leaks.
To achieve these goals, the utility model provides a kind of air conditioner, including compressor, condenser and evaporation
Device, the gas exhaust piping of the compressor connect with the condenser, and the return line of the compressor connects with the evaporator,
The first stop valve is provided with the gas exhaust piping, the second stop valve is provided with the return line；
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 close 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 to flow 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 channel interior between the first stop valve and the second stop valve to form negative pressure, 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, avoids the slow leakage of refrigerant.
Brief description of the drawings
Fig. 1 is the theory structure schematic diagram for the air conditioner that the utility model embodiment provides.
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
Core of the present utility model is to provide a kind of air conditioner, to avoid the system in the heat exchanger of air conditioner and respective line
Cryogen leaks.
In order that those skilled in the art more fully understands technical scheme provided by the utility model, below in conjunction with attached
The utility model is described in further detail with specific embodiment for figure.
As shown in figure 1, the air conditioner that the utility model embodiment provides, including compressor 1, condenser 2 and evaporator 3,
The gas exhaust piping 4 of compressor 1 connects with condenser 2, and the return line 5 of compressor 1 connects with evaporator 3, on gas exhaust piping 4
The first stop valve 6 is provided with, the second stop valve 7 is provided with return line 5；When compressor 1 is opened, the He of the first stop valve 6
Second stop valve 7 is in conducting state；When compressor 1 just stops operating, the first stop valve 6 can close immediately, the
Two stop valves 7, which can be tended to remain on to preset time, to be turned off.Explanation is needed exist for, those skilled in the art are
It should be appreciated that the heat exchanger system of air-conditioning, typically should also have throttling arrangement 8, and the throttling arrangement 8 is set
Put between condenser 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 to flow 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 channel interior between the first stop valve and the second stop valve to form negative pressure, 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, avoids the slow leakage of refrigerant.
In some specific embodiments, preset time corresponding to the time-delay closing of above-mentioned second stop valve is 20 seconds.
Of course, it should be understood that above-mentioned 20 seconds be only the utility model embodiment preferable examples, can also be according to air conditioner
The built-in system facilities selection other times value of corresponding heat exchanger.
In addition, one or two in the above-mentioned stop valve 7 of first stop valve 6 and second can be magnetic valve.Pass through 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
It is that above-mentioned magnetic valve is only the preferable examples of the utility model embodiment 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 this practicality
Other time-delay closing devices realization that the preferable examples of new embodiment or those skilled in the art commonly use, such as directly
Connect controller and control the second stop valve time-delay closing.
Air conditioner provided by the utility model is described in detail above.It should be noted that in this specification
Each embodiment described by the way of progressive, what each embodiment stressed be it is different from other embodiment it
Place, between each embodiment identical similar part mutually referring to.
