According to the air-liquid separator used for the air conditioner, a reasonable structure design enables the external size of the air-liquid separator to be miniaturized; and meanwhile, the long-term heating operation of the air conditioner under the low-temperature operating condition is effectively guaranteed, refrigerant oil can smoothly and completely flow back to a compressor, and the reliability and the stability of the operation of the compressor are enhanced.
Description
Technical field
The present invention relates to a kind of gas-liquid separator, specifically refer to a kind of idle call gas-liquid separator, belong to the air-conditioning production technical field.
Background technology
Idle call gas-liquid separator operated by rotary motion is on the low pressure pipeline between four-way change-over valve and the compressor and near compressor inlet, and the position in air-conditioning system as shown in Figure 1.The effect of gas-liquid separator in air-conditioning system is the refrigerant liquid in separation and the preservation muffler, effectively prevents the appearance of compressor liquid hit phenomenon.And, in gas-liquid separator escape pipe bottom oilhole is set, guarantee in separating the process of preserving refrigerant liquid, to isolate refrigeration oil simultaneously, refrigeration oil is back to compressor, avoids the compressor oil starvation.
Gas-liquid separator is not simply to buy back the gas-liquid separator product from air conditioner parts factory to be assembled on the air-conditioning product or simply to imitate design and just can use, and should be according to self air-conditioning product situation, gas-liquid separator is carried out the reasonable optimizing design improvement, just can give full play to its effect, enhance product performance and reliability.
Establish a spill port and a backsiphonage hole in the structural system of existing idle call gas-liquid separator, as shown in Figure 2, cold-producing medium at flow direction in the gas-liquid separator shown in arrow among Fig. 2.As seen from Figure 2, be siphoned into when machine stops in gas outlet or the compressor for preventing the liquid in the gas-liquid separator, escape pipe generally adopts inner U-shaped structure, on air intake duct top the backsiphonage hole is set.
Such project organization can take the gas-liquid separator inner space, reduces dischargeable capacity, and therefore, gas-liquid separator must amplify to remedy this loss when design; Simultaneously cold-producing medium is with refrigeration lubrication oil dissolves each other or partly molten, lodge in the bottom of gas-liquid separator, or air-conditioning product long-term heating operation under worst cold case, lamination appears in liquid refrigerant and refrigeration lubrication oil, because of liquid refrigerant density greater than the refrigeration lubrication oil density, refrigeration lubrication oil reservoir in the gas-liquid separator is in liquid refrigerant layer top, spill port near escape pipe bottom is difficult to guarantee that refrigeration oil flows back to compressor smoothly, and at this moment liquid refrigerant has part and flows back to compressor from spill port.
Summary of the invention
Deficiency at the prior art existence, technical problem to be solved by this invention is, a kind of idle call gas-liquid separator, make the external dimensions miniaturization of gas-liquid separator by reasonable structural design, simultaneously, effectively guarantee air conditioner long-term heating operation under worst cold case, refrigeration oil can be back to compressor smoothly completely, strengthens the reliability and stability of compressor operation.
For solving the problems of the technologies described above, the technical solution used in the present invention is, a kind of idle call gas-liquid separator is provided, comprise cylindrical shell, air inlet pipe and the escape pipe that has U-shaped pipe, its U-shaped pipe is arranged at the cylindrical shell outside, between escape pipe and the cylindrical shell balance pipe is set, and at least two spill ports are set on the escape pipe.
Above-mentioned idle call gas-liquid separator, its balance pipe is communicated with escape pipe and cylinder lumen.
Above-mentioned idle call gas-liquid separator arranges spill port and following spill port on its escape pipe, last spill port diameter is less than following spill port diameter.
Above-mentioned idle call gas-liquid separator, spill port diameter is 1.0mm-1.5mm on it, and following spill port diameter is 1.5mm-2.0mm, and last spill port is 25mm-35mm with following spill port spacing, and following spill port and cylindrical shell distance from bottom are 15mm-25mm.
Above-mentioned idle call gas-liquid separator, spill port diameter is 1.5mm on it, and following spill port diameter is 2.0mm, and last spill port is 30mm with following spill port spacing, and following spill port and cylindrical shell distance from bottom are 20mm.
The present invention has following advantage and useful technique effect:
1, gas-liquid separator of the present invention is arranged at the cylindrical shell outside with the U-shaped pipe of escape pipe, satisfying under the prerequisite of system requirements, dwindling the overall dimensions of gas-liquid separator, realizing the gas-liquid separator miniaturization, can be good at cooperating the improvement design of air-conditioning volume miniaturization, meet the need of market.
2, the present invention arranges the effect that the balance pipe that is communicated with plays backsiphonage between escape pipe and cylindrical shell, prevents that effectively the liquid in the gas-liquid separator is siphoned into when air-conditioner is shut down in the give vent to anger mouth of pipe or the compressor, the stability of assurance system operation.
3, can satisfy air-conditioning product long-term heating operation under worst cold case, increase spill port by system's practical operation situation at escape pipe, the refrigeration lubrication oil of being convenient to the top oil-enriched layer is back to compressor with the top aperture, more effectively realized that the press oil return avoids the compressor oil starvation, guaranteed the reliability of press runs.
