Abstract

The utility model discloses an air conditioning gas-liquid separator, which comprises a shell and an inlet pipe and an outlet pipe which are communicated into the shell, wherein the inlet pipe is connected with an evaporator, the outlet pipe is connected with a compressor and connected with one end of a U-shaped pipe arranged in the shell, the other end of the U-shaped pipe is provided with a gas outlet, and the bottom of the U-shaped pipe is provided with an oil hole with a filter screen; one end of the inlet pipe positioned in the shell is an internal inlet, and the position of the internal inlet is lower than the gas outlet of the U-shaped pipe; and the bottom of the shell is provided with a balance pipe, and the pipe wall of the U-shaped pipe is provided with a downward bent oil pipe with the filter screen oil hole. The outlet pipe is connected with the U-shaped pipe, the U-shaped pipe is provided with oil pipes with the filter screen oil hole and with a filter for two-time oil return, and the balance pipe used when a plurality of gas-liquid separators are connected in parallel is provided, so compared with the traditional gas-liquid separator, the air conditioning gas-liquid separator has the following advantages of more reasonable structure, capability of separating gas and liquid more thoroughly, better effect and capability of combining the separators together for use.

Description

The air-conditioning gas-liquid separator

Technical field

The utility model relates to air-conditioning unit relevant device technical field, is specifically related to the gas-liquid separator of air-conditioning unit.

Background technology

Therefore the central air-conditioning unit is widely used in heavy constructions such as various hotels, meeting-place, mansion, factory because of its environmental protection and energy saving, function admirable, reliable and stable.In the evaporimeter of air-conditioning, because liquid refrigerant evaporates, become the process of gas by liquid refrigerant in evaporimeter, consider the variation of load, may some all evaporations of cold-producing medium, and can directly enter into compressor.Because the Incoercibility of liquid refrigerant, so before not entering compressor, at first gas-liquid to be separated from each other and come, the low-pressure low-temperature steam that prevents to return compressor carries too much liquid refrigerant and enters compresser cylinder, guarantee that entering the whole of compressor is gas, to guarantee the eupraxic running of compression.At present, gas-liquid separator on the market generally adopts Gravity Separation, has functions such as filtration, oil return, storage liquid, but its structure is comparatively simple, design scientific and reasonablely inadequately, the effect of separation is not very desirable, still the phenomenon that liquid refrigerant enters compressor can take place.

The utility model content

The technical problems to be solved in the utility model provide a kind of combination rationally, the air-conditioning gas-liquid separator of good separating effect.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of air-conditioning gas-liquid separator, comprise the housing of forming separator, be passed into the inlet pipe of enclosure interior and go out pipe, inlet pipe connects the evaporimeter of air-conditioning unit, goes out pipe and connects compressor, it is characterized in that: describedly go out the end that pipe is connected at the U-shaped pipe of enclosure interior, the other end of U-shaped pipe is a gas vent, and U-shaped pipe bottom is provided with band screen pack oilhole; The end that inlet pipe is positioned at housing is inner import, and the position of inner import is lower than the gas vent of U-shaped pipe.

Further, be provided with balance pipe, in order to a plurality of gas-liquid separators and coupling at housing bottom.

Further, the described U-shaped pipe tube wall that connects a side of pipe is provided with the downward oil pipe that has filter of a bending.

Further, the tangent plane of the inside import of described inlet pipe is oval the side cut.

Further, described U-shaped pipe top is provided with spout hole.

The utility model connects the U-shaped pipe by setting out pipe, the oil pipe that band screen pack oilhole and thing filter are set at the U-shaped pipe carries out twice oil return, be provided with the balance pipe that a plurality of gas-liquid separators use when in parallel in addition, compare with traditional gas-liquid separator, the utlity model has following advantage: structure is more reasonable, gas-liquid separation can be got more thorough, better effects if, and can also a plurality of splitter group using altogether.

Description of drawings

Fig. 1 is the utility model three-dimensional structure diagram;

Fig. 2 is the utility model internal structure schematic diagram;

Fig. 3 looks cut-away illustration for the utility model master.

Among the figure, 1 is housing, and 2 is inlet pipe, and 21 is inner import, and 3 for going out pipe, and 4 is balance pipe, and 5 is the U-shaped pipe, and 51 is gas vent, and 52 are band screen pack oilhole, and 6 is oil pipe, and 61 is filter.

The specific embodiment

In the present embodiment, with reference to Fig. 1, Fig. 2 and Fig. 3, described air-conditioning gas-liquid separator, comprise the housing 1 of forming separator, be passed into the inlet pipe 2 of housing 1 inside and go out pipe 3 that inlet pipe 2 connects the evaporimeter of air-conditioning unit, go out pipe 3 and connect compressor, go out the end that pipe 3 other ends are connected at the U-shaped pipe 5 of housing 1 inside, the other end of U-shaped pipe 5 is a gas vent 51, and U-shaped pipe 5 bottoms are provided with band screen pack oilhole 52; The end that inlet pipe 2 is positioned at housing 1 is inner import 21, and the position of inner import 21 is lower than the gas vent 51 of U-shaped pipe 5.U-shaped pipe 5 tops are provided with spout hole (not shown), can flow out from spout hole when liquid refrigerant is too much in the U-shaped pipe 5.

Be provided with balance pipe 4 in housing 1 bottom, in order to a plurality of gas-liquid separators and coupling.

The tube wall that U-shaped pipe 5 connects a side of pipe 3 is provided with the downward oil pipe that has filter 61 6 of a bending.

The tangent plane of the inside import 21 of inlet pipe 2 is oval the side cut.

The refrigerant that includes gaseous state and liquid state is entered in the housing 1 of gas-liquid separator from evaporimeter by inlet pipe 2, liquid refrigerants is stayed in the housing 1, gaseous coolant then from gas vent 51 by U-shaped pipe 5 with go out pipe 3 and enter compressor, lubricating oil is then under the suction of compressor, enter from band screen pack oilhole 52 and oil pipe 6, and enter compressor by going out pipe 5.

Below the utility model is described in detail, the above only is one of the utility model preferred embodiment, when not limiting the utility model practical range, be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
