At present; Common vapour liquid separator basic principle is the proportion that utilizes gas different with liquid; Liquid moment weightlessness was separated from the gas after saturated gas got into separator; And utilizing the flow velocity formation whirlpool of exit gas to make heavy liquid deposition to the separator bottom, the gas after the separation flows out from separator top.
The evaporimeter of air-conditioner generally adopts shunt structure at present, and heat exchange was carried out on several roads parallel with one another after promptly cold-producing medium got into evaporimeter, remerged Cheng Yilu at last, got into compressor through air intake duct.Therefore, need a knockout and accomplish the assignment of traffic of cold-producing medium between each branch road of evaporimeter.Because the liquid refrigerant that comes out from condenser is general earlier through throttling arrangement before getting into the evaporimeter knockout, liquid refrigerant flash distillation becomes the stream-liquid two-phase flow body.The mutual irregular mixing of refrigerant vapour in the two-phase fluid and liquid; And produce the flow velocity slippage because of flow resistance is different; Local flow has unstability and uncertainty, and therefore how effectively controlling the assignment of traffic of cold-producing medium in evaporimeter just becomes the difficult point in the knockout design.If the knockout design is unreasonable; Then flow distribution of refrigerant just maybe be seriously unbalance, and the big branch road of flow is because of the not enough fully heat exchange of heat exchange area, and the heat exchange area surplus then appears in the branch road that flow is little; Thereby cause total heat exchange efficiency of evaporimeter low, and then reduce the performance of air-conditioner.
At present, in the prior art that at home and abroad the air-conditioner manufacturer is adopted, all be directly two phase refrigerant to be shunted.In order to make separatory even as far as possible, let cold-producing medium flow into knockout vertically downward earlier, through the gravity effect, make the bigger refrigerant liquid of density accumulate near the diffluence pass of knockout; Upwards flow along separate routes then, refrigerant vapour promotes refrigerant liquid and gets into each branch road of evaporimeter under the effect of pressure reduction.Sometimes also the isocon that makes progress is designed to certain inclination angle, so that separatory is even as far as possible.The shortcoming of this type knockout is the even separatory that is difficult to ensure two phase flow (because the local flow of two phases has stronger unstability and uncertainty), improves through lot of test often or verifies its performance, has reduced the design efficiency of air-conditioner.
Summary of the invention
The technical problem that the utility model will solve and the technical assignment of proposition are that to overcome existing knockout design unreasonable, cause the low defective of total heat exchange efficiency of evaporimeter, and a kind of hot coil vapour liquid separator of taking back is provided.
For achieving the above object; The hot coil vapour liquid separator of taking back of the utility model comprises low pressure inlet pipe, housing, rich oil liquid outlet, low tension outlet pipe, heat exchange coil, high-pressure inlet pipe, high-pressure outlet pipe; It is characterized in that: described low pressure inlet pipe is from the top access of said housing and near the bottom of housing; Described rich oil liquid outlet is installed in the bottom of said housing; Described low tension outlet pipe is installed in the top of said housing, and described heat exchange coil is fixed on the middle part in the said housing, and described high-pressure inlet pipe, high-pressure outlet pipe are connected to the two ends of said heat exchange coil and extend the outside of said housing.
As the optimization technique measure; The two ends of said heat exchange coil lay respectively at the upper and lower of said housing; Described high-pressure inlet pipe is connected with the superposed end of said heat exchange coil, and described high-pressure outlet pipe is connected with the end that said heat exchange coil is positioned at the bottom.
The hot coil vapour liquid separator of taking back of the utility model is earlier the two phase refrigerant that flows into current divider to be carried out vapor-liquid separation, then the refrigerant liquid after separating is carried out heat exchange, and the refrigerant vapour after separating directly passes through by-pass to compressor inlet.Have the following advantages and good effect: at first, be integral partial design such as vapour liquid separator and heat exchanger, thereby reduce assembling space, simplification pipeline; Secondly, utilize reheat coils to carry out heat exchange, thereby improve condensation effect and liquid evaporation effect, help improving the Energy Efficiency Ratio of air-conditioner, reach energy-conservation effect; The 3rd, further improve or prevent the flash distillation of the too low and anti-solution stopping pipe of degree of superheat refrigerant, can improve the Energy Efficiency Ratio and the protection compressor of unit.The effective heat in the recovery system.
