The specific embodiment

(embodiment 1)

With reference to Fig. 1～Fig. 4, the gas refrigerant separator of first embodiment of the invention is described.

The path of the outlet side of this gas refrigerant separator SG and expansion valve links together; Shown in Fig. 1 (a); Import chamber 10, speedup chamber 20 and derive chamber 30 and combine, and cold-producing medium ingress pipe 11 and gas refrigerant are extracted pipe Pg out and imported chamber 10 and link together with the mode that series connection with one heart links together.In addition, cold-producing medium delivery line 31 links together with derivation chamber 30.In addition, this gas refrigerant separator SG shows the basic structure of extracting out from the gas refrigerant that imports after separate chamber 10.

Import chamber 10 and be cylindric, and have the sidewall 12 that is positioned at speedup chamber 20 opposite sides.In addition; Also adopt following structure: on the internal face of perisporium 13, be formed with the cold-producing medium introducing port 14 that the biphase gas and liquid flow of self-expanding valve in the future imports with the mode along this internal face, and make cold-producing medium after the importing along this internal face rotate (with reference to the arrow of Fig. 2).On this cold-producing medium introducing port 14, be connected with cold-producing medium ingress pipe 11.In addition, the central part at sidewall 12 is connected with gas refrigerant extraction pipe Pg.Through adopting said structure, cold-producing medium rotates along the internal face of perisporium 13, can the gas refrigerant that concentrate on central part be extracted out the pipe Pg from gas refrigerant and extract out.

Speedup chamber 20 forms diameter from importing chamber 10 towards deriving coniform that chamber 30 diminishes.The diameter of the entrance side of this speedup chamber 20 is identical with the diameter that imports chamber 10, and is formed with diameter and not really little connected entrance 21 at front end.In addition, speedup chamber 20 links with derivation chamber 30 through this connected entrance 21.

Derivation chamber 30 forms cylindric, and its diameter is bigger than connected entrance 21, is set to bigger.In addition, derive chamber 30 and have the sidewall 32 that is positioned at and imports chamber 10 opposite sides.Central part at sidewall 32 is connected with cold-producing medium delivery line 31, and the cold-producing medium more than needed of the liquid refrigerant after this cold-producing medium delivery line 31 is used for gas refrigerant is drawn out of is derived (with reference to Fig. 1).

According to the gas refrigerant separator SG that constitutes as stated, divided gas flow cold-producing medium from the cold-producing medium of gas-liquid two-phase stream mode as follows.At first, as shown in Figure 2, biphase gas and liquid flow does not receive flow velocity that gravity effect ground rotates in importing chamber 10 to be imported into columnar importing chamber 10 along the internal face of perisporium 13 enough to make it.If like this, then liquid refrigerant is roughly concentrated along the internal face of perisporium 13 because of centrifugal force, and gas refrigerant concentrates on the central portion of the stream that rotates.In addition, with regard to regard to the stream that rotates that generates in importing chamber 10, if on the center line that runs through the gas refrigerant separator SG that imports chamber 10, speedup chamber 20 and derive chamber 30, form the center of the stream that rotates, the stream that then rotates is stablized and is in desirable state.But the cold-producing medium that in importing chamber 10, generates rotates the initial center of stream might not be consistent with the center of gas refrigerant separator SG.But, through in speedup chamber 20 by speedup, gas and liquid are more clearly separated with central part near the internal face of perisporium, and cold-producing medium rotates the center of stream near the center of derivation chamber 30, make the liquid film homogenization.

Arrow shown in Figure 2 is represented the flow regime of cold-producing medium.Wherein, dotted arrow representes to extract out from gas refrigerant the flow direction of pipe Pg effluent air cold-producing medium.In addition, in following illustrated embodiment, it also is identical separating the arrow of putting down in writing in the relevant accompanying drawing of hold concurrently coolant flow divider and expansion valve with gas refrigerant separator, gas.

In addition, because speedup chamber 20 forms thin coniform of front end, therefore, the rotate diameter of stream of the cold-producing medium that passes this speedup chamber 20 is more little the closer to outlet, thereby can improve the speed that rotates of cold-producing medium.In addition; Diminish and make its speedup through the diameter that rotates that makes cold-producing medium like this, can make cold-producing mediums in the speedup chamber 20 stream that rotates stable, especially; Even if under the situation of the biphase gas and liquid flow that intermittently imports the variation of flowing from cold-producing medium introducing port 14, also can eliminate the discontinuity of its Density Distribution.In addition, through make cold-producing medium rotate diameter the closer to the outlet connected entrance 21 more little, can make cold-producing medium rotate stream the center near central shaft.In addition, when cold-producing medium rotates stream when stablize, speedup chamber 20 interior refrigerant density are scattered in the contour shape of the center circle identical with the center of this speedup chamber 20.Therefore; Can utilize the shape of this speedup chamber 20 realize cold-producing medium the speed that rotates increase and cold-producing medium Density Distribution stabilisation the two; And can omit that the speed that rotates that is used to realize cold-producing medium increases and the special utensil of the Density Distribution stabilisation of cold-producing medium; By this, can simplify the structure of gas refrigerant separator SG.

In addition, owing to the cold-producing medium that flows to speedup chamber 20 from importing chamber 10 is drawn out of gas refrigerant during importing chamber 10, so the ratio of the gas refrigerant in the cold-producing medium reduces.Therefore, the easy homogenization of liquid film, the gas-liquid distributional stability in the speedup chamber 20, the cold-producing medium in importing chamber 10 and the speedup chamber 20 rotate to flow and stablize.In addition, the cold-producing medium from speedup chamber 20 imports the less derivation chamber 30 of diameter from the connected entrance 21 that is formed at speedup chamber 20 front ends.

In that 20 flow directions derive the cold-producing medium jet flow of chamber 30 from the speedup chamber, because the diameter of connected entrance 21 is also not really little, therefore, the centrifugal force that liquid refrigerant flows because of rotating blows out towards the internal face of perisporium 33, and gas refrigerant sprays from central division.Therefore, in deriving chamber 30, form the cold-producing medium of the sneaking into liquid stream that rotates, by this, can make the stream stabilisation that rotates in above-mentioned importing chamber 10 and the speedup chamber 20 along the internal face of perisporium 33.In addition; Even if in importing the chamber; Extract pipe Pg out in case gas refrigerant begins the inflow gas cold-producing medium, also can comparatively fast make the less gas refrigerant of density further concentrate on the center easily, make the cold-producing medium stream stabilisation that rotates because of the flow velocity that sucks; Therefore, can be from the central portion that imports chamber 10 gas bleeding cold-producing medium stably.On the other hand, tapping cold-producing medium cold-producing medium more than needed from the cold-producing medium delivery line 31 of being located at sidewall 32 central parts of deriving chamber 30.

In Fig. 4, just derive chamber 30 and show the basic configuration that all can consider, but this derivation chamber 30 is equivalent to the grown form III among Fig. 4.As for other basic configuration, will explain explicitly with the embodiment of following explanation.

Then, according to the refrigerant loop of Fig. 3, an example of the refrigerating plant of the gas refrigerant separator of formation describes to using as above.

This refrigerant loop is the refrigerant loop of heat pump type air conditioner.This refrigerant loop shows heating with gas refrigerant separator and the cooling gas refrigerant separator example together that is connected to each other.In the refrigerant loop figure of Fig. 3, solid arrow is represented the flow direction of cold-producing medium when cooling operation, and dotted arrow representes to heat the flow direction that heats when turning round.In the refrigerant loop figure of following explanation, also be identical.

That is, four-way switching valve 2 links together with the outlet and the suction inlet of compressor 1.In addition, between the switch terminal 2a of this four-way switching valve 2,2b, be connected with outdoor heat exchanger 3 in turn, heat the coolant flow divider 4A of usefulness, the gas refrigerant separator SG that heats usefulness, the DYN dynamic expansion valve 5A of usefulness, DYN dynamic cooling expansion valve 5B, cooling gas refrigerant separator SG, cooling cold-producing medium separator 4B, the indoor side heat exchanger 6 of heating.In addition; The gas refrigerant that heats the gas refrigerant separator SG of usefulness is extracted out between pipe Pg is connected the outlet side of evaporimeter when heating via bypass circulation 7A the outdoor heat exchanger 3 and four-way switching valve 2, acting outdoor heat exchanger 3 bypass of evaporimeter when this bypass circulation 7A heats conduct.In bypass circulation 7A, be inserted with check valve 8A, this check valve 8A is used to stop when refrigeration from extracting the situation of managing the Pg bypass out towards gas refrigerant between outdoor heat exchanger 3 and the four-way switching valve 2.In addition; Identical therewith; When the gas refrigerant of cooling gas refrigerant separator SG is extracted pipe Pg out and is connected as refrigeration via bypass circulation 7B between the outdoor heat exchanger 3 and four-way switching valve 2 of the outlet side of evaporimeter, this bypass circulation 7B makes acting indoor side heat exchanger 6 bypass of evaporimeter when freezing.In bypass circulation 7B, be inserted with check valve 8B, this check valve 8B is used to stop when heating from extracting the situation of managing the Pg bypass out towards gas refrigerant between indoor side heat exchanger 6 and the four-way switching valve 2.

In the air conditioner that as above constitutes; Discharge gas after discharging from compressor 1 when cooling operation by outdoor heat exchanger 3 condensations, and via the coolant flow divider 4A that heats usefulness, heat the gas refrigerant current divider SG of usefulness and heat the expansion valve 5A of usefulness and flow towards cooling expansion valve 5B.Then, in cooling expansion valve 5B, be depressurized and expand and become biphase gas and liquid flow, and import cooling gas refrigerant separator SG.The cold-producing medium that imports behind the gas refrigerant separator SG is drawn out of gas refrigerant through above-mentioned effect, gas refrigerant utilize bypass circulation 7B and bypass to outlet side as the acting indoor side heat exchanger 6 of evaporimeter.In addition, in cooling gas refrigerant separator, the liquid refrigerant cold-producing medium more than needed that is in after the gas refrigerant extraction is shunted in cooling coolant flow divider 4B, and mobile towards a plurality of refrigerant passage that constitute indoor side heat exchanger 6.Then, towards a plurality of refrigerant passage flowing liquids refrigeration refrigerant cools room air more than needed, make cold-producing medium self evaporation and become gas refrigerant.This gas refrigerant and the gas refrigerant interflow of coming from gas refrigerant separator SG bypass, and be back to compressor 1.At the coolant flow divider 4A that heats usefulness and heat among the gas refrigerant separator SG of usefulness, because the direction circulation in the opposite direction of cold-producing medium court and the original function of performance, so these equipment only just work as refrigerant passage.

In addition; Discharge gas after compressor 1 is discharged heats room air and is condensed indoor side heat exchanger 6 when heating running; And flow towards the expansion valve 5A that heats usefulness via cooling coolant flow divider 4B, cooling gas refrigerant separator SG and cooling expansion valve 5B; Then in this heats the expansion valve 5A of usefulness, be depressurized and expand and become biphase gas and liquid flow, and import the gas refrigerant separator SG that heats usefulness.The cold-producing medium that imports behind the gas refrigerant separator SG is drawn out of gas refrigerant through above-mentioned effect, gas refrigerant utilize bypass circulation 7A and bypass to outlet side as the acting outdoor heat exchanger 3 of evaporimeter.In addition, being among the coolant flow divider 4A that liquid refrigerant cold-producing medium more than needed heating usefulness after in heating the gas refrigerant separator SG of usefulness, gas refrigerant being extracted out shunted, and flows towards a plurality of refrigerant passage that constitute outdoor heat exchanger 3.Then, towards cold-producing medium and the outdoor air heat exchange more than needed of a plurality of refrigerant passage flowing liquids refrigeration,, cold-producing medium self is evaporated and become gas refrigerant from the extraneous gas draw heat.This gas refrigerant and the gas refrigerant interflow of coming from gas refrigerant separator SG bypass, and be back to compressor 1.In cooling coolant flow divider 4B and cooling gas refrigerant separator SG, because the direction circulation in the opposite direction of cold-producing medium court and the original function of performance, so these equipment only just work as refrigerant passage.

In this refrigerating plant, SG comes to move as follows through using gases cold-producing medium separator.

By in the cold-producing medium of shunting, gas refrigerant significantly reduces, and therefore, can improve significantly towards the bias current of each isocon Pd in coolant flow divider 4A, 4B.In addition; In acting heat exchanger (outdoor heat exchanger 3 or indoor side heat exchanger 6) as evaporimeter; Because the cold-producing medium more than needed of the liquid refrigerant after having gas refrigerant to be drawn out of flows into, and therefore can improve the surface heat transfer coefficient in the heat exchanger.In addition, because of gas refrigerant reduces the circulating resistance of cold-producing medium is reduced.In addition; Since the cold-producing medium in the refrigerant passage of evaporimeter after the evaporation with from the cold-producing medium of gas refrigerant separator SG bypass interflow and be back to compressor 1; So as long as make mixed cold-producing medium be in the suitable degree of superheat, thereby can reduce from the degree of superheat of the cold-producing medium of evaporimeter outflow through regulating this bypass amount.Therefore, in acting outdoor heat exchanger 3 and indoor side heat exchanger 6, can significantly improve heat exchanger effectiveness through this effect as evaporimeter.

Gas refrigerant separator and refrigerating plant according to first embodiment that as above constitutes can play following effect.

(1) because gas refrigerant separator SG constitutes by importing chamber 10, speedup chamber 20 and deriving chamber 30, thereby can make the cold-producing mediums that import in the chamber 10 rotate the stream stabilisation not receive the influence of gravity.Therefore, can relax the restriction relevant when being assembled into gas refrigerant separator SG in the refrigerating plant, become easy thereby make to handle with installation direction.

(2) the speedup chamber can utilize and form the speed that rotates and the stabilisation that coniform such simple structure increases cold-producing medium.By this, in the restriction on relaxing installation direction, can more stably carry out the extraction of gas refrigerant.In addition,, also can eliminate the discontinuity of its Density Distribution, therefore, reduce flow of refrigerant sound in this case such as expansion valve even if under the situation of the biphase gas and liquid flow that intermittently imports the variation of flowing from cold-producing medium introducing port 14.

(3) through being assembled to refrigerant loop, gas refrigerant separator SG reduces the refrigerant gas amount in the cold-producing medium that is delivered to evaporimeter.Therefore, because of carrying out the shunting among coolant flow divider 4A, the 4B, the reasons such as surface heat transfer coefficient raising in the evaporimeter easily equably, the heat exchanger effectiveness in evaporimeter improves.

(4) since in importing chamber 10 the gas bleeding cold-producing medium, so the ratio of the gas refrigerant that flows to speedup chamber 20 in the cold-producing medium reduces, and makes the gas-liquid distributional stability in the speedup chamber 20.Consequently, make the cold-producing medium that imports in chamber 10 and the speedup chamber 20 stream stabilisation that rotates.

(second embodiment)

Then, with reference to Fig. 5～Fig. 7, the gas refrigerant separator of second embodiment is described.

SG is different with the situation of first embodiment for this gas refrigerant separator, shows from deriving chamber 30 gas bleeding cold-producing mediums and with the basic structure of its separation.

The situation of this gas refrigerant separator SG and first embodiment is identical to be connected with the outlet side of expansion valve.In addition, shown in Fig. 2 (a), import chamber 10, speedup chamber 20 and derivation chamber 30 and combine with the mode that links of connecting with one heart.In addition, cold-producing medium ingress pipe 11 links together with importing chamber 10, and cold-producing medium delivery line 31 and gas refrigerant are extracted pipe Pg out and derived chamber 30 and link together.

The situation that imports chamber 10 and first embodiment is identical to be cylindric, and is formed with sidewall 12 in the side of the opposite side of speedup chamber 20.In addition, also adopt following structure: on the internal face of perisporium 13, be formed with the cold-producing medium introducing port 14 that the biphase gas and liquid flow of self-expanding valve in the future imports with the mode along this internal face, and make cold-producing medium after the importing along internal face rotate (with reference to the arrow of Fig. 6).In addition, on cold-producing medium introducing port 14, be connected with cold-producing medium ingress pipe 11.

Coniform that chamber 30 diameters diminish derived with identical the forming from importing chamber 10 courts of situation of first embodiment in speedup chamber 20.The diameter of the entrance side of this speedup chamber 20 is identical with the diameter that imports chamber 10, and is formed with diameter and not really little connected entrance 21 in front.In addition, speedup chamber 20 links with derivation chamber 30 through this connected entrance 21.The size of connected entrance 21 and first embodiment are in roughly the same degree.

Derive chamber 30 and be cylindric, form the diameter bigger, i.e. bigger diameter than the diameter of connected entrance 21.Yet in order in this derivation chamber 30, cold-producing medium to be rotated, the internal diameter of deriving chamber 30 forms forr a short time than the internal diameter that imports chamber 10.In addition, the side of an opposite side of importing chamber 10 forms the shape that links continuously with cold-producing medium delivery line 31.Therefore, cold-producing medium delivery line 31 is to form big footpath with the smooth mode that becomes that is connected that derives chamber 30, and gas refrigerant is extracted pipe Pg out and to constitute the such form of interior pipe of this cold-producing medium delivery line 31 as the double pipe of outer tube is being configured.In addition, gas refrigerant extraction pipe Pg is supported at the part place of running through cold-producing medium delivery line 31.Like this, gas refrigerant is extracted pipe Pg out and is configured to the gas refrigerant extraction with the central part of the cold-producing medium stream that rotates that concentrates on above-mentioned derivation chamber 30.In addition, cold-producing medium delivery line 31 is configured to the liquid refrigerant that rotates the on every side cold-producing medium more than needed of extracting pipe Pg at this gas refrigerant out is derived.

Gas refrigerant separator SG according to above formation; Identical with the situation of first embodiment; The cold-producing medium of biphase gas and liquid flow imports with the mode along the internal face of perisporium 13 from cold-producing medium introducing port 14, and in importing chamber 10, rotates with the intensity that does not receive gravity effect.Then, liquid refrigerant is roughly concentrated along the internal face of perisporium 13 because of centrifugal force, only has gas refrigerant to concentrate on to rotate the central portion of stream.In addition owing to import that the stream that rotates that generates in the chamber 10 receives the effect identical with the situation of embodiment one in speedup chamber 20 speedup, thereby make the center stabilisation of the stream that rotates.

In addition, the cold-producing medium of speedup chamber 20 is fed to the bigger derivation chamber 30 of diameter from diameter and the not really little connected entrance 21 that is formed at speedup chamber 20 front ends.Because connected entrance 21 forms and not really little diameter, therefore, from the cold-producing medium jet flow of flow direction derivation chambers 30 20, speedup chamber, the centrifugal force that liquid refrigerant flows because of rotating blows out towards the internal face of perisporium 33, and gas refrigerant sprays from central division.Therefore, in deriving chamber 30, the cold-producing medium of sneaking into liquid rotates along the internal face of perisporium 33, the stream thereby the cold-producing medium that forms the center of the center that will derive chamber 30 flowing as rotating rotates.In addition; Owing to utilize towards the gas refrigerant of the central part opening of deriving chamber 30 and extract pipe Pg out, therefore can be formed on flowing of gas refrigerant stable on the central shaft of extracting out from the central authorities of connected entrance 21 to gas refrigerant till the pipe Pg from deriving the central portion gas bleeding cold-producing medium of chamber 30.Like this, because it is stable to derive cold-producing mediums in the chamber 30 stream that rotates, therefore gas bleeding cold-producing medium stably.This derivation chamber 30 is equivalent to the grown form III among Fig. 4.

Then, according to the refrigerant loop of Fig. 7, an example of the refrigerating plant of the gas refrigerant separator SG of formation describes to using as above.

This refrigerant loop is identical with the refrigerant loop of the heat pump type air conditioner of Fig. 3, just gas refrigerant separator SG is changed into the gas refrigerant separator SG of this embodiment, and other structure and action are identical with first embodiment.

Because the gas refrigerant separator of second embodiment and use the refrigerating plant of this gas refrigerant separator to adopt above structure, therefore can play the identical effect of effect with (1)～(3) of first embodiment, in addition, can also play following effect.

(5) in deriving chamber 30; Owing to utilize towards the gas refrigerant of the central part opening of deriving chamber 30 and extract pipe Pg out, therefore can be formed on flowing of gas refrigerant stable on the central shaft of extracting out from the central authorities of connected entrance 21 to gas refrigerant till the pipe Pg from deriving the central portion gas bleeding cold-producing medium of chamber 30.By this, can make the extraction stabilisation of gas refrigerant.

(6) become double pipe through making and derive the structure that cold-producing medium delivery line 31 that chamber 30 links together and gas refrigerant extract pipe Pg out, can simplify.

(the 3rd embodiment)

Then, with reference to Fig. 8 and Fig. 9, the gas refrigerant of the 3rd embodiment is separated the coolant flow divider of holding concurrently describe.

The gas refrigerant that the 3rd embodiment relates to the gas-liquid separation mechanism that uses above-mentioned gas cold-producing medium separator separates double coolant flow divider and uses this gas refrigerant to separate the refrigerating plant of double coolant flow divider.

It is on the basis of first embodiment that the gas refrigerant of the 3rd embodiment separates the coolant flow divider DR that holds concurrently; Form the diameter of deriving chamber 30 slightly little, and change cold-producing medium delivery line 31 into a plurality of isocon Pd that a plurality of refrigerant passage with evaporimeter are connected to.Therefore, compare with first embodiment, importing chamber 10 and speedup chamber 20 are identical, derive chamber 30 differences.

Derive chamber 30 and be cylindric, its diameter forms lessly (when comparing with the derivation chamber 30 of first embodiment, diameter is less).

In addition; The gas refrigerant of this embodiment separates a plurality of (being three here) isocon Pd that the coolant flow divider DR that holds concurrently uses the refrigerant passage with evaporimeter to link together, with as the cold-producing medium delivery line 31 among the gas refrigerant separator SG of first embodiment.These isocons Pd is equally spaced disposed on certain circumference.In addition; Cold-producing medium for fear of importing from connected entrance 21 is directly sucked isocon Pd; And near the cold-producing mediums the perisporium 33 that can liquid refrigerant be concentrated suck, and the radius r 1 of the circular arc that the inner surface that makes three isocon Pd is linked together forms greatlyyer than the radius r 2 of connected entrance 21.

Therefore, with regard to the action in this gas refrigerant separates the coolant flow divider DR that holds concurrently, it is identical with the situation of first embodiment to import cold-producing medium in chamber 10 and the speedup chamber 20 stream that rotates.In addition, because from importing chamber 10 gas bleeding cold-producing mediums, the ratio regular meeting of the gas refrigerant in the cold-producing medium that therefore in speedup chamber 20, flows reduces.Therefore, the easy homogenization of liquid film, the gas-liquid distributional stability in the speedup chamber 20, the cold-producing medium in importing chamber 10 and the speedup chamber 20 rotate to flow and stablize, thereby make gas refrigerant from importing the extraction stabilisation of chamber 10.

In addition, in that 20 flow directions derive the flow of refrigerant of chamber 30 from the speedup chamber, because the diameter of connected entrance 21 is also not really little, therefore, the centrifugal force that liquid refrigerant flows because of rotating blows out towards the internal face of perisporium 33, and gas refrigerant sprays from central division.Therefore, in deriving chamber 30, the cold-producing medium that blows out towards the internal face of perisporium 33 collides with the internal face of perisporium 33, and is stirred because of this collision.In addition, owing to form axisymmetric flow of refrigerant, therefore can make the stream stabilisation that rotates in above-mentioned importing chamber 10 and the speedup chamber 20 from the internal face of perisporium 33 towards center flow.In addition; Even if in importing chamber 10; Extract pipe Pg out in case gas refrigerant begins the inflow gas cold-producing medium, also can comparatively fast make the less gas refrigerant of density further concentrate on the center easily, make the cold-producing medium stream stabilisation that rotates because of the flow velocity that sucks; Therefore, can be from the central portion that imports chamber 10 gas bleeding cold-producing medium stably.

In addition, in deriving chamber 30,, has function as current divider though the gas-liquid of cold-producing medium distributes and the flow regime of cold-producing medium is identical with above-mentioned grown form II (with reference to Fig. 4) basically.

In the cold-producing medium that is inhaled into isocon Pd in this derivation chamber 30, extract out because gas refrigerant is extracted out pipe Pg by gas refrigerant, so the ratio of gas refrigerant is less.In addition, because therefore isocon Pd can carry out the cold-producing medium shunting equably at the cold-producing medium stream part opening that becomes from the internal face of perisporium 33 towards the axisymmetric flow of refrigerant of center flow.In addition, owing to form like this cold-producing medium stream that rotates, so can eliminate the influence of the installation direction when refrigerating plant is assembled.

Fig. 9 representes to be assembled with the refrigerant loop that the gas refrigerant that as above constitutes separates the refrigerating plant of the coolant flow divider of holding concurrently.Refrigerant loop words relatively with first embodiment that illustrates among Fig. 3; In the first embodiment; Between cooling expansion valve 5B and indoor side heat exchanger 6, be connected with gas refrigerant separator SG and cooling coolant flow divider 4B; In addition, also between expansion valve 5A that heats usefulness and outdoor heat exchanger 3, be connected with gas refrigerant separator SG and the coolant flow divider 4A that heats usefulness.Yet; In the refrigerant loop of this embodiment; As shown in Figure 9; Only, just can play the effect identical with the situation of first embodiment through between cooling expansion valve 5B and the indoor side heat exchanger 6 and be connected gas refrigerant respectively between the expansion valve 5A that is heating usefulness and the outdoor heat exchanger 3 and separate the coolant flow divider DR that holds concurrently.

That is separate the to hold concurrently container of coolant flow divider DR of the gas refrigerant that, constitutes this embodiment is formed the member of one, is constituted the member of deriving the sidewall 32 relative with connected entrance 21 in the chamber 30 and form by the perisporium and the perisporium 33 of deriving chamber 30 that constitute the member that imports chamber 10, speedup chamber 20 shown in Figure 25 (a).

In constitute importing the member of chamber 10, the perisporium 13 that imports chamber 10 is formed one with the sidewall 12 that is positioned at the opposition side of speedup chamber 20, and perisporium 13 and sidewall 12 the two linked together smoothly.In addition, the diameter of perisporium 13 20 enlarges and links together with speedup chamber 20 towards the speedup chamber.Make the situation of enlarged-diameter of perisporium 13 identical like this with the situation of the 7th embodiment.In addition, sidewall 12 is shaped as inner wall surface thereof 12a and is bent local spherical (part of sphere) of lateral bending outwardly with the central shaft of this chamber as the center.Cold-producing medium ingress pipe 11 is identical with the situation of the 5th embodiment, and the mode and the cold-producing medium introducing port 14 that import cold-producing medium with the internal face along perisporium 13 link together.

The perisporium of speedup chamber 20 is identical with the situation of the 5th embodiment, forms from importing chamber 10 towards deriving coniform that chamber 30 diameters diminish.

In addition, the perisporium 33 of derivation chamber 30 forms the taper shape that enlarges gradually from the connected entrance 21 of speedup chamber 20.In addition, in this embodiment, the perisporium of speedup chamber 20 and the perisporium 33 of deriving chamber 30 be by one-body molded, and form the wall that is smooth surface across connected entrance 21.

Then, the sidewall 32 of derivation chamber 30 is formed by the tabular component of heavy wall.In addition, the core of the internal face 32a of sidewall 32 is cut the shape that is processed into formation partial sphere shape and lateral bending is bent outwardly, that is, the internal face 32a of sidewall 32 is cut to be processed into to be and forms the also shape of depression of local spherical curved surface.In addition, the side view of the derivation chamber side that illustrates like Figure 25 (b), near this sidewall 32 is formed with periphery a plurality of (being specially 18) isocon connecting hole 32b.On this each isocon connecting hole 32b, be connected with isocon Pd.

The mobile of cold-producing medium of importing chamber 10 of this embodiment and derivation chamber 30 is described below.The cold-producing medium that 13 inner peripheral surface imports from cold-producing medium introducing port 14 along perisporium separates the coolant flow divider DR that holds concurrently with this gas refrigerant mounting position onrelevant ground formation cold-producing medium in importing chamber 10 stream that rotates.When such formation cold-producing medium rotates stream, rotate near perisporium 13 because of density contrast makes liquid cold-producing medium more than needed, and gas cold-producing medium more than needed is rotated at central part.Yet, in this cold-producing medium rotates stream, import in the chambers 10, so cold-producing medium rotates, and not necessarily to separate the central shaft of the coolant flow divider DR that holds concurrently consistent with this gas refrigerant for the center of stream because cold-producing medium flows into from a cold-producing medium introducing port 14.

Yet; In this embodiment; The core of the internal face 12a of sidewall 12 forms local spherical shape and lateral bending is bent outwardly; Utilize rotate center bent local spherical of lateral bending outwardly of stream of cold-producing medium, can form the delay portion that does not carry out only having the speed composition that rotates from the initial outflow of its central part.By this, the cold-producing medium stream that rotates is corrected near the gas refrigerant direction at center of coolant flow divider DR and stable of separate holding concurrently.In addition, because the diameter of perisporium 13 that imports chamber 10 20 enlarges towards the speedup chamber, therefore can make the cold-producing medium stream that rotates flow to the mobile composition of speedup chamber 20.Like this, because perisporium 13 forms the guide wall with 20 guiding towards the speedup chamber of cold-producing medium stream, therefore, Yi Bian can separate the mounting position onrelevant ground of the coolant flow divider DR that holds concurrently cold-producing medium is successfully rotated towards speedup chamber 20, Yi Bian mobile with gas refrigerant.

In addition, the flow of refrigerant till from speedup chamber 20 to derivation chamber 30 is described below.
