Abstract
The utility model relates to a gas-liquid separator which is suitable for multiple compressors, and is connected with an air-conditioning system in parallel, which relates to the gas-liquid separator in the air-conditioning technique field. The utility model comprises a casing body of a gas-liquid separator, a cooling agent inlet pipe and an air intake duct which are connected with the upper end of the casing body. The structure characters of the utility model are that the cooling agent inlet pipe is a main pipe which is communicated with the inner cavity of the casing body. The air intake duct is a plurality of U-shape pipes which are arranged on the lower end of the inner cavity of the casing body, the U-shaped section on the lower end of each air intake duct is provided with a plurality of oil absorption holes. Compared with the prior art, the gas-liquid separator can lead lubricating oil which is accumulated in a system pipeline to be smoothly brought back to the compressor and lead each compressor to evenly return oil, and meanwhile, air-breathing pressure and air-breathing amount of each compressor are basically the same.
Description
Technical field
The utility model relates to the gas-liquid separator of air-conditioning technical field, is applicable to particularly that multiple compressors is connected in parallel to constitute the gas-liquid separator of air-conditioning system.
Background technology
In the air-conditioning system of multi-compressor multi-joint machine in parallel, even be provided with oil eliminator at each compressor air-discharging end, still can be mingled with lubricating oil in the cold-producing medium and enter system with cold-producing medium, the bad meeting of compressor oil-supplying causes compressor damage, and the quality of oil return situation is to the performance safety important influence of whole system.When refrigerating operaton, the cold-producing medium that compressor flows in this section of off-premises station pipeline is a high temperature and high pressure gas, and very high flow velocity is arranged, cold-producing medium and lubricating oil can be good at mixing, so the cold-producing medium of storing in this section pipeline seldom, and in off-premises station, cold-producing medium is the high-temperature liquid state cold-producing medium, lubricating oil and cold-producing medium solubility are bigger, therefore also can trapped fuel at this section of off-premises station pipeline.Export to compressor inlet at indoor set, cold-producing medium becomes the low-temp low-pressure of certain degree of superheat gas, and flow velocity is lower, and most of lubricating oil separates with refrigerant gas, and this section pipeline can accumulate a large amount of lubricating oil.Heating circulation time as a same reason, off-premises station exports to compressor inlet also can stockpile a large amount of lubricating oil.Therefore solving in this section lubricating oil, to stockpile problem be the key that solves the oil return problem.In the in parallel multi-joint machine of the multi-compressor of the prior art system, every compressor all is to suck refrigerant gas by a common air suction main from gas-liquid separator.Because the caliber of air suction main is thicker, during underrun in the pipe air velocity slower, if be lower than low strap speed oil, lubricating oil just is difficult to return compressor, causes compressor oil-supplying bad and make compressor damage.
Summary of the invention
For solving above-mentioned problems of the prior art, the utility model provides a kind of gas-liquid separator that is applicable to air conditioning system with multi-compressor parallel connection.It can make the pressure of inspiration(Pi) of every compressor and inspiratory capacity basic identical the taking back compressor and the make every compressor oil return even of lubricating oil smoothness of accumulating in the system pipeline simultaneously.
To achieve the above object of the invention, the utility model adopts following technical scheme:
Be applicable to the gas-liquid separator of air conditioning system with multi-compressor parallel connection, it comprises the housing of gas-liquid separator and cold-producing medium inlet pipe and the air intake duct that links to each other with the housing upper end.Its design feature is that described cold-producing medium inlet pipe is that a house steward communicates with the inner chamber of housing.Described air intake duct is the many U type pipes that place housing inner chamber bottom, and the lower end U type section of each air intake duct is provided with a plurality of oil-sucking holes.
In above-mentioned gas-liquid separator, the radical setting of described air intake duct equates with the number of compressors of air-conditioning system.
The utility model is owing to adopted technique scheme, the multiplex system cryogen that flows out from evaporator/condenser imports the cold-producing medium inlet pipe, every compressor all has the air intake duct of independently drawing from gas-liquid separator, effectively reduced the caliber of air intake duct, so that when minimum load in the pipe air velocity also can be higher than low strap speed oil, can in pipe, not form amass oily.Because a plurality of oil-sucking holes that are positioned at differing heights on the air intake duct make the high and low howsoever variation of liquid level of gas-liquid separator, lubricating oil also can both be inhaled into air intake duct.Big cavity in the gas-liquid separator housing can guarantee the steady relatively of the interior lubricating oil liquid level of gas-liquid separator, solved the problem of the oil return deficiency that exists in the in parallel multi-joint machine of the multi-compressor system, and guarantee that every compressor oil return is even, make the pressure of inspiration(Pi) of every compressor basic identical, air-breathing more even.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model air intake duct;
Fig. 3 is the connection diagram that the utility model is used.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises the housing 1 of gas-liquid separator and cold-producing medium inlet pipe 2 and four air intake ducts 3 that link to each other with housing 1 upper end.Cold-producing medium inlet pipe 2 is that a house steward communicates with the inner chamber 11 of housing 1.The multiplex system cryogen that flows out from each evaporator/condenser 4 flows into housing 1 inner chamber 11 through cold-producing medium inlet pipe 2.Air intake duct 3 is the many U type pipes that place housing 1 inner chamber 11 bottoms, and the lower end U type section of each air intake duct 3 is provided with a plurality of oil-sucking holes 32.
Referring to Fig. 3, when the utility model used, the cold-producing medium that flows out from each evaporator 4 imported cold-producing medium inlet pipe 2 through cross valve 6, and enters the inner chamber 11 of gas-liquid separator housing 1.A large amount of refrigerant gas accumulate in the top of inner chamber 11, lubricating oil and a spot of refrigerant liquid are positioned at inner chamber 11 bottoms, refrigerant gas is sucked by four compressors 5 by the air entry 31 on four air intake ducts 3, lubricating oil enters each air intake duct 3 by oil-sucking hole 32, is taken back in each compressor 5 by refrigerant gas.
What deserves to be explained is that the radical setting of described air intake duct 3 equates with the quantity that is provided with of the compressor 5 of air-conditioning system.Corresponding air intake duct 3 radicals are connected and the multi-joint machine system circuit of multi-compressor parallel connection that constitutes is protection domain of the present utility model in suchlike employing multiple compressors 5 and the playscript with stage directions utility model gas-liquid separator 7.
