Abstract
The present invention provides a kind of gas-liquid separator for air conditioner, and including cylinder, air inlet pipe and the escape pipe with U-tube, its U-tube is arranged at outside cylinder, arranges balance pipe between escape pipe and cylinder, and escape pipe arranges at least two spill port. Being made the external dimensions miniaturization of gas-liquid separator by rational structural design, meanwhile, be effectively ensured 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.
Description
Technical field
The present invention relates to a kind of gas-liquid separator, specifically refer to a kind of gas-liquid separator for air conditioner, belong to air-conditioning production technical field.
Background technology
Gas-liquid separator for air conditioner is generally located on the low pressure pipeline between four-way change-over valve and compressor and near compressor inlet, position within air-conditioning systems is as shown in Figure 1. Gas-liquid separator effect within air-conditioning systems is the coolant liquid separating and preserving in muffler, effectively prevents the appearance of compressor liquid hit phenomenon. And, oilhole is set bottom gas-liquid separator escape pipe, it is ensured that in separating the process preserving coolant liquid, concurrently separating out refrigeration oil, refrigeration oil is back to compressor, it is to avoid compressor oil starvation.
Gas-liquid separator is not simply bought back gas-liquid separator assembling product from air conditioner parts factory and to air-conditioning products or is carried out simple Imitated design and just can use, and should according to self air-conditioning products situation, gas-liquid separator carries out reasonably optimize design improve, just can give full play to its effect, enhance product performance and reliability.
The structural system of existing gas-liquid separator for air conditioner sets a spill port and a backsiphonage hole, as in figure 2 it is shown, cold-producing medium in gas-liquid separator, flow direction is as shown by the arrows in Figure 2. As seen from Figure 2, for preventing the liquid in gas-liquid separator to be siphoned into when machine stops in gas outlet or compressor, escape pipe is generally adopted internal U-shape structure, arranges backsiphonage hole on suction nozzle top.
Such design structure can take gas-liquid separator inner space, reduces dischargeable capacity, and therefore, gas-liquid separator must be amplified when design to make up this loss; Simultaneously cold-producing medium and refrigeration lubrication oil dissolve each other or half molten, lodge in the bottom of gas-liquid separator, or air-conditioning products long-term heating operation under worst cold case, there is lamination in liquid refrigerant and refrigeration lubrication oil, because liquid refrigerant density is more than refrigeration lubrication oil density, refrigeration lubrication oil reservoir in gas-liquid separator is in above liquid refrigeration oxidant layer, spill port bottom escape pipe is difficult to ensure 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
For the deficiency that prior art exists, the technical problem to be solved is, a kind of gas-liquid separator for air conditioner, the external dimensions miniaturization of gas-liquid separator is made by rational structural design, simultaneously, being effectively ensured 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 above-mentioned technical problem, the technical solution used in the present invention is, a kind of gas-liquid separator for air conditioner is provided, including cylinder, air inlet pipe and the escape pipe with U-tube, its U-tube is arranged at outside cylinder, arranges balance pipe between escape pipe and cylinder, and escape pipe arranges at least two spill port.
Above-mentioned gas-liquid separator for air conditioner, its balance pipe connection escape pipe and cylinder lumen.
Above-mentioned gas-liquid separator for air conditioner, its escape pipe arranges spill port and lower spill port, and upper spill port diameter is less than lower spill port diameter.
Above-mentioned gas-liquid separator for air conditioner, on it, spill port diameter is 1.0mm-1.5mm, and lower spill port diameter is 1.5mm-2.0mm, and upper spill port and lower spill port spacing are 25mm-35mm, and lower spill port and cylinder body bottom distance are 15mm-25mm.
Above-mentioned gas-liquid separator for air conditioner, on it, spill port diameter is 1.5mm, and lower spill port diameter is 2.0mm, and upper spill port and lower spill port spacing are 30mm, and lower spill port and cylinder body bottom distance are 20mm.
The invention have the advantages that and Advantageous Effects:
1, the U-tube of escape pipe is arranged at outside cylinder by the gas-liquid separator of the present invention, under the premise meeting system requirements, reduce the overall dimensions of gas-liquid separator, it is achieved that gas-liquid separator miniaturization, can be good at coordinating the Curve guide impeller of air-conditioning volume miniaturization, meet the market demand.
2, the present invention arranges the balance pipe connected between escape pipe with cylinder and plays the effect of backsiphonage, effectively prevents the liquid in gas-liquid separator to be siphoned into when air-conditioner is shut down and gives vent to anger in the mouth of pipe or compressor, it is ensured that the stability that system is run.
3, disclosure satisfy that air-conditioning products long-term heating operation under worst cold case, on escape pipe, spill port is increased by running situation, the refrigeration lubrication oil being easy to top oil-enriched layer is back to compressor with top aperture, more effective achieve press oil return and avoid compressor oil starvation, it is ensured that the reliability of press runs.
