Abstract
The utility model discloses a gas-liquid separator used for an air-conditioning double-compressor system, which comprises a total gas outlet pipe (7) connected with two gas outlet branch pipes (1), a gas inlet pipe (6) and a barrel body (5), wherein the total gas outlet pipe (7) and the gas inlet pipe (6) are all communicated with the barrel body (5), the bottom of the barrel body (5) is provided with a total oil return pipe (4) which is divided into two oil return branch pipes (3) outside the barrel body (5), and the two oil return branch pipes (3) are respectively communicated with the two gas outlet branch pipes (1) through capillaries (2). After the above structure is adopted, the damage of the compressor caused by no oil in the compressor with smaller displacement is avoided, the oil levels of the compressors with different displacements can be ensured to be at better levels.
Description
Technical field
The utility model relates to the refrigeration and air-conditioning technical field, specifically is that a kind of capacity differs the bigger gas-liquid separator that is used for the air-conditioning double compressor system.
Background technology
The ambient temperature range of air-conditioner work is bigger, at worst cold case evaporator evaporation scarce capacity, perhaps the reaction of the controlling organization of air-conditioner is untimely, all may cause a large amount of refrigerant liquids to return the suction side of compressor, thereby influence the operational efficiency of air-conditioning system.Enter compressor in a large number for fear of liquid refrigerant, the air-conditioning system that refrigerant charge is bigger generally all disposes gas-liquid separator in suction side.Gas-liquid separator generally comprises air inlet pipe, escape pipe and cylindrical shell, and wherein escape pipe is designed to U type pipe in cylindrical shell, and cold-producing medium and oil just can be deposited in the bottom of U type pipe like this.The main effect of gas-liquid separator is the part cold-producing medium in the storage system, prevent that compressor generation liquid hit phenomenon and cold-producing medium from too much diluting compressor oil, it should be able to carry enough cold-producing mediums and oil to get back to compressor, thereby keeps the operational efficiency of system and the pasta in the crankcase.In the air-conditioning system of the multi-compressor of prior art, in order to make multiple compressors draw refrigerant from gas-liquid separator equably, common way is to connect a distributor at the escape pipe place of gas-liquid separator, tell many arms again on distributor, many arms are connected with the import of compressor respectively again.But there is following shortcoming in this structure: the capacity of the compressor that uses in the air-conditioning system of general multi-compressor parallel connection is more or less the same, like this can be so that the refrigeration oil between each compressor reaches balance.When the capacity of two compressors differs big, can cause the big compressor recirculating oil quantity of capacity many, the compressor recirculating oil quantity that capacity is little is few even do not have, and air-breathing like this inhomogeneities can make the compressor damage of not having oil;
The utility model content
Technical problem to be solved in the utility model is a kind of each compressor oil return equilibrium to be provided, thereby to avoid the gas-liquid separator that is used for the air-conditioning double compressor system of compressor damage.
For solving the problems of the technologies described above, the gas-liquid separator that is used for the air-conditioning double compressor system that the utility model provides, comprise and be connected with two total escape pipe, air inlet pipe and cylindrical shells that go out gas branch pipe, described total escape pipe and air inlet pipe all are communicated with cylindrical shell, described cylindrical shell bottom is provided with total oil return pipe, described total oil return pipe is divided into two oil returning branch pipes outside cylindrical shell, described two oil returning branch pipes go out gas branch pipe and are communicated with two by capillary respectively.
After adopting above structure, the utility model compared with prior art, have the following advantages: because two go out on the gas branch pipe and all be connected with the oil return pipe of cylindrical shell by capillary, compressor according to different capacities, determine length capillaceous, the recirculating oil quantity of balanced two compressors is avoided occurring can guaranteeing preferably that the oil level of the compressor that capacity is different is in level preferably because the less interior nothing oil of compressor of capacity causes the phenomenon of compressor damage.
As improvement, described capillary is shape in the shape of a spiral.After adopting the capillary of this shape, make capillary energy reach effect more significantly, damping is stronger.
Description of drawings
Accompanying drawing is the structural representation that the utility model is used for the gas-liquid separator of air-conditioning double compressor system.
Wherein: 1, go out gas branch pipe; 2, capillary; 3, oil returning branch pipe; 4, total oil return pipe; 5, cylindrical shell; 6, air inlet pipe; 7, total escape pipe.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
Be used for by the utility model shown in the drawings the air-conditioning double compressor system gas-liquid separator structural representation as can be known, it comprises and is connected with two total escape pipe 7, air inlet pipe 6 and cylindrical shells 5 that go out gas branch pipe 1, described total escape pipe 7 and air inlet pipe 6 all are communicated with cylindrical shell 5, described cylindrical shell 5 bottoms are provided with total oil return pipe 4, described total oil return pipe 4 is divided into two oil returning branch pipes 3 outside cylindrical shell 5, described two oil returning branch pipes 3 go out gas branch pipe 1 and are communicated with two by capillary 2 respectively.Described capillary 2 is shape in the shape of a spiral.
Like this, when compressor of air conditioner just began to start, the pressure of total escape pipe 7 was lower, caused cold-producing medium and oil in the cylindrical shell 5 to flow toward the gas outlet direction by total oil return pipe 4.By the damping action of capillary 2, suitably weakened the flow of oil return, make oil flow to going out the gas branch pipe 1 separately according to two compressors capacity separately, thereby guarantee that the oil level in the compressor is in horizontal level preferably from two oil returning branch pipes 3.
Claims (2)
1. gas-liquid separator that is used for the air-conditioning double compressor system, comprise and be connected with two total escape pipe (7), air inlet pipe (6) and cylindrical shells (5) that go out gas branch pipe (1), described total escape pipe (7) and air inlet pipe (6) all are communicated with cylindrical shell (5), it is characterized in that: described cylindrical shell (5) bottom is provided with total oil return pipe (4), described total oil return pipe (4) is divided into two oil returning branch pipes (3) outside cylindrical shell (5), described two oil returning branch pipes (3) go out gas branch pipe (1) and are communicated with two by capillary (2) respectively.
2. the gas-liquid separator that is used for the air-conditioning double compressor system according to claim 1 is characterized in that: described capillary (2) is shape in the shape of a spiral all.
