The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Shown in Fig. 2 and Fig. 3, according to embodiment of the present utility model, gas-liquid separator comprises housing 10, many oil return pipes 20, tube connector 30 and control parts 40, wherein, housing 10 encloses and forms container cavity 11, container cavity 11 comprises a plurality of isolated areas 12, and a plurality of isolated areas 12 are separated the solution in container cavity 11; Many oil return pipes 20 are communicated with correspondingly with a plurality of isolated areas 12, in oil return process, and the corresponding oil return pipe 20 of fluid in an isolated area 12; Tube connector 30 is arranged between every adjacent two oil return pipes 20; Control part 40 is arranged on tube connector 30 break-make with control connection pipe 30.
According to the present embodiment, between adjacent two oil return pipes 20, by tube connector 30, connect, on tube connector 30, be provided with the control part 40 of control connection pipe 30 break-makes, in system one or a few compressor 100 break down and shut down or unit is long-time while opening fixing compressor 100 load operation, or the oil that the corresponding isolated area 12 of compressor 100 stores cannot carry out circulation time in system, by the control action of control part 40, fluid in other isolated areas 12 can be delivered to corresponding oil return pipe 20, avoid the phenomenon of long-time compressor 100 oil starvations of opening fixing compressor 100 load operations and causing moving of shutdown or unit, thereby improve the service life of compressor 100 and the operational reliability of compressor bank.
The gas-liquid separator of the present embodiment also comprises blast pipe 60, this blast pipe 60 be arranged on the top of housing 10 and be positioned at housing 10 outside, and be communicated with container cavity 11, prevent that blast pipe 60 is arranged in container cavity 11 and causes the pressure loss of gas-liquid separator.Blast pipe 60 is many in the present embodiment, and many blast pipes 60 arrange correspondingly with a plurality of isolated areas 12, and the refrigerant after gas-liquid separator separates is delivered to corresponding compressor 100.
Preferably, the first end of many oil return pipes 20 is connected to the bottom of a plurality of isolated areas 12 correspondingly, and the oil return pipe 20 and the blast pipe 60 that are arranged in same isolated area 12 are communicated with in housing 10 outsides, owing to there being larger gas flow rate in blast pipe 60, make blast pipe 60 and oil return pipe 20 interface pressure be less than the pressure of gas-liquid separator bottom, by this pressure reduction, made the fluid of container cavity 11 bottoms arrive blast pipe 60 places by oil return pipe 20, by blast pipe 60, get back in compressor 100.
Preferably, gas-liquid separator also comprises air inlet pipe 70, and this air inlet pipe 70 is arranged on the top of housing 10, and what guarantee to return through evaporimeter does not evaporate on a small quantity cold-producing medium completely and can access good separation.Air inlet pipe 70 is many, and many air inlet pipe 70 arrange correspondingly with a plurality of isolated areas 12.More preferably, the first end of each air inlet pipe 70 all stretches into container cavity 11, and the opening of the first end of air inlet pipe 70 many blast pipes 60 far away, the cold-producing medium of avoiding entering gas-liquid separator from evaporimeter is without separated and directly from blast pipe 60 drainage gas-liquid separators, and the sidewall more than liquid level of the opening of the first end of air inlet pipe 70 in container cavity 11, avoids the cold-producing medium that enters gas-liquid separator directly to rush at the liquid of gas-liquid separator bottom and cause the liquid splash of bottom.
Refer again to shown in Fig. 2 and Fig. 3, according to embodiment of the present utility model, gas-liquid separator also comprises a plurality of separators 50, a plurality of separators 50 are along container cavity 11 length directions successively spaced set, container cavity 11 is divided into a plurality of isolated areas 12, thereby the fluid of gas-liquid separator inside is separated into multiply, and multiply fluid is delivered to a plurality of compressors 100 by oil return pipe 20 correspondingly.In the present embodiment, separator 50 is baffle plate.In other embodiment of the present utility model, separator 50 can also be that other can be isolated into container cavity 11 a plurality of isolated areas 12 with by the separated structure of fluid of container cavity 11 bottoms.It should be noted that, in the present embodiment, baffle plate is only that the fluid of container cavity 11 bottoms is separated, and in the upper end of baffle plate, whole container cavity 11 communicates, and that can return to evaporimeter does not evaporate on a small quantity cold-producing medium completely and can access good separation.
In the present embodiment, control part 40 comprises controller 41, and this controller 41 is arranged on tube connector 30 break-make with control connection pipe 30.In system one or a few compressor 100 break down and shut down or unit is long-time while opening fixing compressor 100 load operation; by the control action of controller 41; fluid in other isolated areas 12 can be delivered in corresponding oil return pipe 20; fluid flows into corresponding blast pipe 60 and then enters corresponding compressor 100 from oil return pipe 20, prevents that petrol starvation from appearring in compressor 100.More preferably, controller 41 is switch valve.In other embodiments, controller 41 can also be the structure that other can control connection pipe 30 break-makes.
Below in conjunction with Fig. 3, specifically introduce specific operation process of the present utility model:
Three baffle plates are divided into four isolated areas 12 by gas-liquid separator bottom, the fluid of its storage through oil return pipe 20 by inspiratory airflow respectively with being back in the crankcase of corresponding compressor 100.When certain compressor 100 is shut down, the switch valve on the side of its corresponding isolated area 12 is connected, thereby makes oil in the corresponding isolated area 12 of institute can participate in the normal circulation of unit, guarantees that system has enough fluid to participate in moving.
According to another embodiment of the present utility model, air-conditioner comprises gas-liquid separator, and gas-liquid separator is above-mentioned gas-liquid separator.
Above-described embodiment of the present utility model has been realized following technique effect:
1) while preventing from shutting down because of compressor fault or because of logic, cause parts of lubricating oil to form dead angle, the phenomenon that cannot circulate, guarantees system oil normal circulation.
2) during unit sub-load, and the compressor of operation and the air-cooler of operation be not upper and lower when symmetrical in position, and the switch valve of opening on pipeline can make the normal oil return of system, the reliability service of guarantee unit.
3) can avoid the phenomenon of the long-time compressor oil starvation of opening fixing compressor load operation and causing moving of shutdown or unit, the service life of compressor and operational reliability in raising system.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
