Description
Technical field
The utility model relates to air conditioner technical field, particularly relates to a kind of low noise gas-liquid separator and air-conditioner.
Background technology
In the evaporimeter of air-conditioning, evaporate in evaporimeter because there is liquid, become the process of gas from liquid, owing to considering the change of load, some refrigerant all may not evaporate, and directly can enter into compressor.Due to the Incoercibility of liquid, so before not entering compressor, first to pass through gas-liquid separator, to guarantee to enter the whole in gas of compressor, ensure the eupraxic running of compression.
Gas-liquid separator is installed on the entrance point of compressor, and mainly prevent the low-pressure low-temperature steam returning compressor from carrying too much drop, prevent liquid refrigerant from entering compresser cylinder, gas-liquid separator has the functions such as filtration, oil return, storage liquid simultaneously.
Gas-liquid separator in existing multiple on-line system, as shown in Figure 1, the gas-liquid two-phase refrigerant of being come by outer machine condenser divides inlet pipe 2 to enter gas-liquid separator from gas, gas-liquid two-phase refrigerant is separated, gaseous coolant goes out pipe 1 by top gas and flows out, and the through hole 5 ' of liquid refrigerants bottom liquid pipe goes out pipe 3 from liquid and flow out.Under refrigeration mode, the refrigerant liquid level of gas-liquid separator inside there will be fluctuation, is liquid when causing liquid to go out refrigerant in pipe 3, time and be gaseous state, produce significantly discontinuous, intermittent noise, approximate " breathing ", have a strong impact on air-conditioning noise quality; In addition, if to go out the through hole 5 ' bottom pipe 3 less with the bottom space of gas-liquid separator for the liquid of existing gas-liquid separator, refrigerant by slit enter liquid go out pipe 3 time, can other noises such as howling be produced, affect air-conditioning noise reduction equally; And due to technique restriction, the bad guarantee of uniformity of gas-liquid separator, may cause certain batch of noise producing part very large.
As shown in Figure 2, in figure, the direction of arrow is refrigerant flow direction, the air-flow of existing gas-liquid separator a-quadrant in fig. 2 goes out the rigid plane of pipe 3 with the liquid of higher velocity shock larger area, form air-flow at rigid plane to peel off, reflect and friction, produce larger noise, air velocity is larger, and noise is larger; , can there is obvious whirlpool in B region in fig. 2, produce larger aerodynamic noise, whirlpool energy is larger, and noise is larger near the liquid sucting port of through hole 5 '.Especially when the refrigerant liquid level in gas-liquid separator is instantaneously lower than through hole 5 ', can not suddenly change at the inside and outside differential pressure of drain pipe 3, the moment of through hole 5 ' imbibition transfers air-breathing to, under same pressure differential, gaseous coolant flow velocity enlarges markedly, go out the rigid plane of pipe 3 with higher velocity shock liquid, vortex core energy increases severely simultaneously, thus produces larger noise.
