Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the present invention can be defined by the claims and cover
Multitude of different ways implement.
See shown in Fig. 2 and Fig. 3, according to embodiments of the invention, gas-liquid separator include housing 10, many oil return pipes 20,
Connecting tube 30 and control portion 40, wherein, housing 10 encloses and sets formation receiving chamber 11, accommodates chamber 11 and includes multiple isolation area 12,
The solution accommodated in chamber 11 is separated by multiple isolation areas 12；Many oil return pipes 20 connect correspondingly with multiple isolation areas 12,
During oil return, the corresponding oil return pipe 20 of the fluid in an isolation area 12；Connecting tube 30 is arranged on the most adjacent two and returns
Between oil pipe 20；Control portion 40 is arranged in connecting tube 30 to control the break-make of connecting tube 30.
According to the present embodiment, connected by connecting tube 30 between adjacent two oil return pipes 20, connecting tube 30 is provided with control even
The control portion 40 of adapter 30 break-make, when in system or a few compressor 100 break down shutdown or unit open for a long time
When opening fixing compressor 100 load operation, or the oil that the isolation area 12 corresponding to compressor 100 stores cannot enter in system
During row circulation, by the control action in control portion 40, the fluid in other isolation areas 12 can be delivered to the oil return pipe of correspondence
20, it is to avoid shut down or unit is opened fixing compressor 100 load operation for a long time and caused compressor 100 oil starvation of operation
Phenomenon, thus improve the service life of compressor 100 and the operational reliability of compressor bank.
The gas-liquid separator of the present embodiment also includes exhaustor 60, and this exhaustor 60 is arranged on the top of housing 10 and is positioned at housing
Outside 10, and connect with accommodating chamber 11, in preventing exhaustor 60 to be arranged on receiving chamber 11, cause the pressure of gas-liquid separator to damage
Lose.Exhaustor 60 is many in the present embodiment, and many exhaustors 60 are arranged correspondingly with multiple isolation areas 12, will be through
Coolant after gas-liquid separator separates is delivered to the compressor 100 of correspondence.
Preferably, the first end of many oil return pipes 20 is connected to the bottom of multiple isolation area 12 correspondingly, and is arranged on
Oil return pipe 20 on same isolation area 12 and exhaustor 60 are at housing 10 ft connection, owing to there being bigger gas in exhaustor 60
Rate of flow of fluid, makes exhaustor 60 and oil return pipe 20 seam pressure less than the pressure bottom gas-liquid separator, this pressure reduction makes receiving
Fluid bottom chamber 11 arrives at exhaustor 60 by oil return pipe 20, is returned in compressor 100 by exhaustor 60.
Preferably, gas-liquid separator also includes air inlet pipe 70, and this air inlet pipe 70 is arranged on the top of housing 10, it is ensured that through evaporation
What device was returned a small amount of do not evaporate cold-producing medium completely and can well be separated.Air inlet pipe 70 is many, many air inlet pipe 70
Arrange correspondingly with multiple isolation areas 12.It is highly preferred that the first end of each air inlet pipe 70 all stretches into receiving chamber 11, and enter
The most exhaustors 60 of the opening of the first end of trachea 70, it is to avoid from vaporizer enter gas-liquid separator cold-producing medium the most separated and
Directly from exhaustor 60 drainage gas-liquid separator, and the opening of the first end of air inlet pipe 70 towards the liquid level accommodated in chamber 11 with
On sidewall, it is to avoid enter gas-liquid separator cold-producing medium directly rush at the liquid bottom gas-liquid separator and cause bottom liquid
Splash.
Referring again to shown in Fig. 2 and Fig. 3, according to embodiments of the invention, gas-liquid separator also includes multiple separator 50, many
Receiving chamber 11, along accommodating chamber 11 length direction spaced set successively, is divided into multiple isolation area 12 by individual separator 50, thus will
Fluid within gas-liquid separator is separated into multiply, and multiply fluid is delivered to multiple compressor by oil return pipe 20 correspondingly
100.In the present embodiment, separator 50 is baffle plate.In other embodiments of the invention, separator 50 can also is that other
Multiple isolation area 12 can be isolated into the structure separated by the fluid accommodated bottom chamber 11 by accommodating chamber 11.It should be noted that
In the present embodiment, baffle plate is only to separate accommodating the fluid bottom chamber 11, in the upper end of baffle plate, and whole receiving chamber 11
Communicate, it is possible to that returns vaporizer a small amount of do not evaporate cold-producing medium completely and can well be separated.
In the present embodiment, control portion 40 includes controller 41, and this controller 41 is arranged in connecting tube 30 to control connecting tube
The break-make of 30.When in system or a few compressor 100 break down shutdown or unit open fixing compression for a long time
During machine 100 load operation, by the control action of controller 41, the fluid in other isolation areas 12 can be delivered to accordingly
Oil return pipe 20 in, fluid flows into corresponding exhaustor 60 from oil return pipe 20 and then enters corresponding compressor 100, prevents pressure
There is petrol starvation in contracting machine 100.It is highly preferred that controller 41 is switch valve.In other embodiments, controller 41 also may be used
Being that other can control the structure of connecting tube 30 break-make.
The specific operation process of the present invention is specifically introduced below in conjunction with Fig. 3:
Three pieces of baffle plates will be divided into four isolation areas 12 bottom gas-liquid separator, its store fluid through oil return pipe 20 by inspiratory airflow
Respectively in the crankcase of the compressor 100 that band is back to correspondence.When certain compressor 100 is shut down, its corresponding isolation area 12
Side switch valve connect so that the oil in corresponding isolation area 12 can participate in the normal circulation of unit, it is ensured that system
Enough fluid is had to participate in running.
According to another embodiment of the present invention, air-conditioner includes gas-liquid separator, and gas-liquid separator is above-mentioned gas-liquid separator.
The above embodiment of the present invention achieves techniques below effect:
1) prevent because of compressor fault or because of logic shut down time, cause parts of lubricating oil formed dead angle, it is impossible to the phenomenon of circulation, really
Insurance system lubricating oil normal circulation.
2) during unit sub-load, and when the air-cooler of the compressor of operation and operation is not the most symmetrical above and below, pipe is opened
Switch valve on road can make the normal oil return of system, ensures the reliability service of unit.
3) shutdown or unit can be avoided to open fixing compressor load for a long time run and cause showing of the compressor oil starvation run
As, service life of compressor and operational reliability in raising system.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for those skilled in the art
For, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of being made, etc.
With replacement, improvement etc., should be included within the scope of the present invention.
