Abstract

The utility model discloses a gas-liquid separator for an air-conditioning system, which comprises an air outlet pipe (1), an air inlet pipe (5) and a cylinder (4). The air outlet pipe (1) and the air inlet pipe (5) are communicated with the cylinder (4). An oil return pipe (3) is arranged at the bottom of the cylinder (4). The oil return pipe (3) outside the cylinder (4) is communicated with the air outlet pipe (1) through a capillary pipe (2). After the adoption of the above structure, a pressure equalizing pore arranged on the air outlet pipe is eliminated, only the capillary pipe on the oil return pipe is increased to play a role in damping, and the length of the capillary pipe is determined according to oil return only, thereby avoiding massive experiments from checking during designing and greatly simplifying design difficulty. In addition, the structure is simpler.

Description

The gas-liquid separator that is used for air-conditioning system
Technical field
The utility model relates to the refrigeration and air-conditioning technical field, specifically is a kind of gas-liquid separator that is used for air-conditioning 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.The capacity of the compressor that uses in the air-conditioning system of the multi-compressor parallel connection of prior art is more or less the same, like this can be so that the refrigeration oil between each compressor reaches balance.Therefore, escape pipe place at gas-liquid separator U type pipe is provided with balancing orifice, and when compressor just brought into operation, the pressure of gas outlet was lower like this, hydraulic pressure cold-producing medium of storing in the U type pipe and oil will flow to the gas outlet direction along U type pipe, just can control the size of recirculating oil quantity by balancing orifice.The excessive recirculating oil quantity in aperture is just little even can not oil return, and the too small recirculating oil quantity in aperture is just big, so the size of balancing orifice has directly influenced the size of recirculating oil quantity.And the balancing orifice aperture determine obtain by a large amount of experimental verifications, its development difficulty is very big.
The utility model content
Technical problem to be solved in the utility model is, a kind of simple in structure, gas-liquid separator that is used for air-conditioning system that design difficulty is little is provided.
For solving the problems of the technologies described above, the gas-liquid separator that is used for air-conditioning system that the utility model provides, comprise escape pipe, air inlet pipe and cylindrical shell, described escape pipe and air inlet pipe all are communicated with cylindrical shell, described cylindrical shell bottom is provided with oil return pipe, and described oil return pipe is communicated with escape pipe by capillary outside cylindrical shell.
After adopting above structure, the utility model compared with prior art, have the following advantages: owing to cancelled the balancing orifice that is arranged on the escape pipe, just increased the effect that capillary on the oil return pipe reaches damping, only need to decide length capillaceous according to recirculating oil quantity, thereby a large amount of experimental verification when having avoided design, simplified design difficulty greatly, structure is simpler simultaneously.
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
Fig. 1 is the structural representation of prior art gas-liquid separator;
Fig. 2 is the structural representation that the utility model is used for the gas-liquid separator of air-conditioning system.
Wherein:
Prior art: 1 ', escape pipe; 4 ', cylindrical shell; 5 ', air inlet pipe; 6 ', balancing orifice; 7 ', spill port.
The utility model: 1, escape pipe; 2, capillary; 3, oil return pipe; 4, cylindrical shell; 5, air inlet pipe.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
By the structural representation of prior art gas-liquid separator shown in Figure 1 as can be known, it comprises escape pipe 1 ', air inlet pipe 5 ', cylindrical shell 4 ', described escape pipe 1 ' and air inlet pipe 5 ' all are communicated with cylindrical shell 4 ', escape pipe 1 ' is designed to U type pipe in cylindrical shell 4 ', be provided with spill port 7 ' in U type bottom, be provided with balancing orifice 6 ' on the top of escape pipe 1 '.Like this, when compressor of air conditioner just begins to start, the pressure of escape pipe 1 ' is lower, cause cold-producing medium and oil in the U type pipe to flow toward the gas outlet, at this moment air inlet pipe 5 ' air inlet is sent into from balancing orifice 6 ', the pressure in the balance U type pipe, the pore size of control balancing orifice 6 ' is controlled at pressure the cold-producing medium of a part and oil are flowed in the compressor of air conditioner.
Be used for by the utility model shown in Figure 2 air-conditioning system gas-liquid separator structural representation as can be known, it comprises escape pipe 1, air inlet pipe 5 and cylindrical shell 4, described escape pipe 1 and air inlet pipe 5 all are communicated with cylindrical shell 4, described cylindrical shell 4 bottoms are provided with oil return pipe 3, and described oil return pipe 3 is communicated with escape pipe 1 by capillary 2 outside cylindrical shell 4.Described capillary 2 is shape in the shape of a spiral.Equally, when compressor of air conditioner just began to start, the pressure of escape pipe 1 was lower, caused cold-producing medium and oil in the cylindrical shell 4 to flow toward the gas outlet direction by oil return pipe 3, like this by the damping action of capillary 2, had suitably weakened the flow of oil return.
