One running action-
Below, describe about the running of described refrigerating plant 1 action.
When starting described refrigerating plant 1, each compressor 11,12 entry into service in refrigerant loop 10, after each expansion valve 15,17 was configured to suitable aperture, cold-producing medium circulated according to the direction shown in Fig. 1 arrow.
From the high-pressure refrigerant of the senior side compressor 12 ejections outdoor heat converter 14 of flowing through, and after the outdoor air heat release, condensing.Curdy cold-producing medium is flowed through and is reduced to intermediate pressure behind the intermediate expansion valve 15, and becomes the cold-producing medium of gas-liquid two-phase state.
The flow through inflow pipe 20 of gas-liquid separator 18 of the cold-producing medium of described gas-liquid two-phase state, and by grid mesh part 50.At this moment, the bubble in this gas-liquid two-phase state cold-producing medium is by refinement.Just, the gas-liquid two-phase cold-producing medium in the inflow pipe 20 becomes slug flow as shown in Figure 2, and the bubble 80 that is formed by big gaseous refrigerant piece flows therein.Be box lunch when being in described situation, bubble 80 also can become small bubble 81 by refinement by grid mesh part 50 backs.Consequently the gas-liquid two-phase cold-producing medium becomes the uniform state that is dispersed with micro bubble 81 in liquid refrigerant.
And, since this grid mesh part 50 be arranged on openend 21 near, so the gas-liquid two-phase cold-producing medium is in the inside that keeps being imported under the situation of uniform state vessel 16.Particularly described gas-liquid two-phase cold-producing medium is imported into the inside of vessel 16 with the form that falls gently to liquid refrigerant storage portion 23 from openend 21, and this openend 21 is towards the below that becomes miter angle with vertical.
So, because the gas-liquid two-phase cold-producing medium is imported in the vessel 16 with stable flow regime, so can reduce because bubble that 23 foamings of liquid refrigerant storage portion produce and the liquid refrigerant that causes because of the liquid fluctuating of this liquid refrigerant storage portion 23 splash.And, the gas-liquid two-phase cold-producing medium that imports in vessel 16 is separated into liquid refrigerant and gaseous refrigerant, this gaseous refrigerant is stored in the gaseous refrigerant storage portion 24 on vessel 16 tops, and described liquid refrigerant is stored in the liquid refrigerant storage portion 23 of vessel 16 bottoms.
The liquid refrigerant of vessel 16 described liquid effuser 30 backs of flowing through are reduced to low pressure and expand by main expansion valve 17 time.Dilated cold-producing medium when flowing through freezing heat-exchanger 13, air heat absorption back evaporation in the storehouse, thus air in the storehouse is cooled off.
Vaporized cold-producing medium is inhaled into rudimentary side compressor 11, sprays after being compressed into intermediate pressure.And, after via the gaseous refrigerant of gas effuser 40 in the ejection cold-producing medium of this intermediate pressure has been supplied with the vessel 16 of described gas-liquid separator 18, be inhaled into senior side compressor 11.
The effect of-embodiment one-
In described refrigerating plant 1, because the inflow pipe 20 at gas-liquid separator 18 is provided with grid mesh part 50, thereby can positively carry out refinement to the bubble 80 that forms by gaseous refrigerant in the gas-liquid two-phase cold-producing medium of the inflow pipe 20 of flowing through, so can make this gas-liquid two-phase cold-producing medium become uniform state.Thus, because the gas-liquid two-phase cold-producing medium is imported into vessel 16 with rule and stable flow regime, thus can reduce liquid refrigerant storage portion 23 liquid fluctuating, because the liquid refrigerant that causes of this fluctuation splashes and since the bubble that causes at liquid refrigerant storage portion 23 generation bubbles etc. sneak into.
And, because described inflow pipe 20 is set to the form that whole along continuous straight runs extends, so the air pocket piece that is formed by gaseous refrigerant in the gas-liquid two-phase fluid becomes and breaks easily, and from by just suppressing the generation of air pocket 80 before the grid mesh part 50.
Also have, in described gas-liquid separator 18, the top that the openend 21 of described inflow pipe 20 and the openend 41 of gas effuser 40 are arranged on vessel 16 is gaseous refrigerant storage portion 24, and be configured to the side of this openend 21 towards vessel 16, this openend 41 is towards the opposite side of this side of vessel 16.Can prevent that consequently the gas-liquid two-phase cold-producing medium from directly being imported liquid refrigerant storage portion 23 from the openend 21 of described inflow pipe 20, and can prevent the inwall of the gas-liquid two-phase cold-producing medium collision vessel 16 that flows into from the openend 21 of described inflow pipe 20 and the phenomenon of splashing produces.Therefore, can prevent that bubble from sneaking into the liquid fluctuating of this liquid refrigerant storage portion 23 and this fluid liquid storage portion 23.
And, since the openend 21 of described inflow pipe 20 in the about 45 degree backs of bending below tiltedly, so can prevent really further that the gas-liquid two-phase cold-producing medium from colliding the housing section of vessel 16.And, because with compare with respect to the vertical situation about falling of liquid level of the liquid refrigerant storage portion 23 in the vessel 16, the gas-liquid two-phase cold-producing medium is more gently fallen, so can reduce the liquid fluctuating of liquid refrigerant storage portion 23 and the phenomenon of foaming.
And the openend 41 of gas effuser 40 is arranged on a side relative with the openend 21 of described inflow pipe 20 in vessel 16, but also is set at the top of the openend 21 of described inflow pipe 20.Therefore, can prevent from directly to flow out from described gas effuser 40 to the gas-liquid two-phase cold-producing medium that vessel 16 flows into from described inflow pipe 20.
Also have,, when liquid effuser 30 flows out, can prevent that gaseous refrigerant is blended into this liquid refrigerant at liquid refrigerant because the openend 31 of described liquid effuser 30 is arranged on the liquid refrigerant storage portion 23 of vessel 16 bottoms.
As mentioned above, by each pipeline 20,30,40 of gas-liquid separator 18 is set, thereby can prevent that gaseous refrigerant is blended into from liquid refrigerant storage portion 23 flows to the liquid refrigerant of liquid effuser 30.And, can also prevent from that liquid refrigerant is blended into from gaseous refrigerant storage portion 24 to flow to the gaseous refrigerant of gas effuser 40.The gas-liquid separation performance is improved.
Also have, in described refrigerating plant 1, because the gas-liquid separation performance of the gas-liquid separator 18 in the refrigerant loop 10 improves,, can realize the stabilisation that turns round thus so can make the evaporability of freezing heat-exchanger 13 and the condensation ability of outdoor heat converter 14 realize stabilisation.The reliability of refrigerating plant 1 is improved.
