Technical field

The present invention relates to have the kind of refrigeration cycle that is used to carry out cooling down operation and be used for giving birth to the refrigeration plant that thermic devices is collected the rankine cycle of used heat from for example internal combustion engine etc.The invention further relates to the compound fluid machinery that will be applied to refrigeration plant, wherein fluid machinery has the effect of the compressor set that is used for compressing and pumps working fluid and is used for effect by the expansion gear that makes the working fluid expansion output mechanical energy of working in rankine cycle.The invention further relates to the method for operating that is used to control refrigeration plant, relate in particular to the method for operating that stops rankine cycle.

Background technology

Wherein the integrally formed compound fluid machinery of compressor set, expansion gear, drive motors and pump is well known in the art, for example shown in the Japan Patent publication No.H8-86289 (rotating machinery of Scroll piston is shown).In above-mentioned compound fluid machinery, each unit Series arranges, and (compressor set is by the magnet coupling device or be connected directly to expansion gear) coaxially to each other.Compressor set is used for the cold-producing medium of compression refrigeration circulation, and expansion gear is handled by the working fluid in the rankine cycle.

According to above-mentioned fluid machinery, in initial (beginning) stage of expansion gear, expansion gear drives a period of time by drive motors, becomes stable up to the operation of expansion gear.Then, expansion gear is driven by making working fluid (by the burner heating, the to be transformed into the high pressure-temperature working fluid) expansion in the rankine cycle, thereby it is by the driving force rotation of himself.Driving force directly or indirectly (passing through magnet coupling) is delivered to compressor set, to operate on it, makes working fluid be compressed.Pump is also handled by the driving force that produces at the expansion gear place, so that the working fluid cycles in the rankine cycle.

As mentioned above, giving birth to thermic devices (for example burner) is to need especially in above-mentioned prior art equipment.The present inventor has developed the refrigeration plant that is used for motor vehicle, and wherein the used heat from internal combustion engine is collected, and is used to handle rankine cycle, thereby considers grovel heating (grovelwarming), can reduce energy consumption.

Be used under the situation of motor vehicle at above-mentioned prior art equipment, wherein the used heat from engine is used as thermal source (replacement burner), when the waste heat from engine can not obtain driving force by expansion gear more after a little while.During this period, compressor set can be handled by drive motors.Yet in this case, pump is also handled by drive motors with compressor set, has reduced the efficient of drive motors operate compressor.

On the other hand, not under the situation that (not to require the cooling down operation of kind of refrigeration cycle) in the operation of compressor set, even when the used heat that can fully obtain from engine, can stop the operation of expansion gear yet.As a result, used heat can not be effective to collect the energy that expansion gear produces.

According to the fluid machinery of another prior art, for example as shown in Japan Patent publication No.2004-232492, fluid machinery has the function of compressor and the function of expansion gear equally.According to this prior art fluid machinery, wherein as the flow direction of the working fluid under the situation of compressor device works with opposite as the flow direction of the working fluid under the situation of expansion gear work.First fluid (discharging) mouth and first (discharging) valve gear are set in the fluid machinery, make compressed working fluid be pumped out by first fluid (discharging) mouth.And second fluid flow port (inlet) and second (inlet) valve gear are set in the fluid machinery, make the high pressure-temperature working fluid be supplied in the expansion gear.When fluid machinery was operated as compressor set, second fluid flow port (inlet) was closed by second valve gear (electrically operated on-off valve device).

Yet according to above-mentioned fluid means, the volume of second fluid flow port becomes the dead volume (dead volume: thereby can not be pumped out the volume of the working fluid of staying the operating room during squeeze operation) of the squeeze operation that is used for fluid machinery inevitably.This is a problem, particularly, when in order to allow the extensive work fluid to flow into the operating room of expansion gear the internal diameter of second fluid flow port being designed to when big, or is designed to hour when the amount of the working fluid that pumps from compressor set for each rotation.

According to another prior art refrigeration plant, for example as shown in Japan Patent publication No.S56-43018, refrigeration plant is used for motor vehicle, wherein compressor set is connected with expansion gear, so that compressor set is by drive force, wherein said driving force is produced by the expansion gear that is used to from the used heat of engine is handled.Yet, in this refrigeration plant, when during used heat can not the warm-up operation at engine, being collected, can not carry out cooling down operation.Particularly, even after parking under the burning sun of vehicle in summer, require under the situation of big cooling capacity in order to cool off vehicle interior fast, as long as can not collect sufficient used heat from engine, then cooling down operation is exactly impossible.

Therefore, the present inventor has proposed a kind of refrigeration plant that is used for motor vehicle in its Japanese patent application No.2004-227006, wherein, compressor set separates with expansion gear, compressor set is driven by engine or drive motors, and is used for producing the pump that electric power and/or driving are used to make the working fluid cycles of rankine cycle from the energy of expansion gear.According to the refrigeration plant that proposes above, though when not having used heat the cooling down operation possibility that also becomes, and when having sufficient waste heat, can be by rankine cycle harvest energy effectively.

Yet, according to the refrigeration plant that proposes above, consider environmental protection, if refrigeration plant is applied to have the vehicle of idling shut-down operation, when stopping temporarily, power operation can not carry out cooling down operation.

According to another prior art, for example, as shown in the Japan Patent publication No.2004-108220, electric power produces at the generator place that is driven by expansion gear, and wherein said expansion gear will be handled in rankine cycle, to collect used heat.

Dynamotor is handled by no sensor control method usually, according to the method, and the rotatable phase of prediction generator, rather than use phase detector, thus realize generator cheaply.

The operation that can not prevent generator in this no sensor control method fully becomes out of control, the result, and its normal operating state is left in operation.Therefore, in the operation of generator (driving) when leaving its normal operating state by expansion gear, the operation of generation outage machine usually.Then, owing to be removed,, and can exceed and allow rotational energy level so the rotation of expansion gear can be accelerated to the load of expansion gear.If this situation takes place, then noise may produce at the expansion gear place, and depends on the circumstances, and expansion gear may be damaged.And, may produce high voltage at the generator place, cause related electric part or the impaired problem of device possibility.

Even the operation of generator by situation from the signal controlling of position sensor under, be out of order if be used for the controller (converter) of generator, then the operation of generator also may become out of control, and can quicken and damage the rotation of expansion gear.

In view of the above problems, make the present invention.

Circulate the kind of refrigeration cycle 30 that the low pressure port 121a by heater 43, switch valve 44, condenser 31, gas-liquid separator 32, dropping equipment 33, evaporimeter 34, check-valves 34b, inflate compression machine 110 forms from the cold-producing medium of high-pressure mouth 111c discharging, thereby carry out cooling down operation by the heat absorption operation of evaporimeter 34.Because engine cooling water (hot water) do not flow in the heater 43, thus cold-producing medium in heater 43, be not heated, thereby heater 43 is only as the part work of coolant channel.

Because pump shaft 134 (small diameter portion 134d) is owing to one-way clutch 140 no longer meshes with motor shaft 124, so refrigerated medium pump 130 is not worked under this pattern.

(expansion mechanism)

In expansion mechanism, when the cooling down operation that no longer needs kind of refrigeration cycle 30, and can be when engine 10 obtains fully many used heat (when the temperature of engine cooling water abundant when high), high pressure superheater cold-producing medium by heater 43 heating is supplied with in the inflate compression machine 110, so that the cold-producing medium in the expansion gear 110 expands.Removable spool 113 rotates by the expansion of cold-producing medium, to obtain to be used to make the driving force (mechanical energy) of motor shaft 124 rotations.The driving force rotation of the rotor 123 of dynamotor 120 by obtaining like this producing electric power, and charges into battery 13 with the electric power that is produced.

More specifically, switch valve 44 cuts out by the control module (not shown), and engine cooling water is by three-way valve 21 circulations, to flow in the heater 43.Dynamotor 120 is as power generator work (rotation) in the opposite direction, and opens magnetic valve 117 by valve body 117d, to open inlet 116.

In this operation, the pump shaft 134 (small diameter portion 134d) of refrigerated medium pump 130 is by one-way clutch 140 and motor shaft 124 engagements, so that drive refrigerated medium pump 130 rotations.By high-pressure section 111c, hyperbaric chamber 114 with enter the mouth and 116 infeed among the V of operating room, make cold-producing medium in the V of operating room, expand by the high pressure superheater cold-producing medium of heater 43 heating.Expansion by cold-producing medium make removable spool 113 with compact model in rotate on the opposite direction, the rotary driving force that imposes on axle 118 is delivered to the motor shaft 124 and the rotor 123 of dynamotor 120.When the driving force that passes to motor shaft 124 becomes when being higher than refrigerated medium pump 130 needed driving forces, dynamotor begins to rotate as power generator.And, the electric power that is obtained is charged in the battery 13 by transverter 12.

Pressure is owing to the cold-producing medium that reduces that expands flows out from low pressure port 121a.The cold-producing medium that flows out from low pressure port 121a circulates rankine cycle 40, and wherein said rankine cycle 40 comprises second bypass channel 42, check-valves 42a, condenser 31, gas-liquid separator 32, first bypass channel 41, check-valves 41a, refrigerated medium pump 130, heater 43 and inflate compression machine 110 (high-pressure mouth 111c).Refrigerated medium pump 130 will be supplied with heater 43 from the liquid phase refrigerant of gas-liquid separator, wherein with pressurizes refrigerant to pressure corresponding to the temperature of the cold-producing medium of the overheated evaporation that produces at heater 43.

(the 3rd embodiment)

The 3rd embodiment shown in Figure 10 to 13, the difference of this embodiment and first and second embodiment be following some.

At first, will difference in the structure of fluid machinery 100B be described referring to Figure 10.

Remove the refrigerated medium pump 130 of first embodiment from the fluid machinery 100B of the 3rd embodiment.The axle head of motor shaft 124 is supported rotationally by the bearing 141 that is fixed to electric machine casing 121.

Inlet 116 is communicated with the V of operating room with the one end.And enter the mouth 116 with hyperbaric chamber 114 openings of its other end court in the part of close floss hole 115,116 the channel region of wherein entering the mouth is designed to big inadequately, thus in overheated gasified refrigerant by 116 pressure losses that are not enough to produce cold-producing medium when flowing into the V of operating room that enter the mouth.As shown in Figure 11, inlet 116 forms in the substrate 112a of fixing spool 112, and forms L shaped.Inlet 116 part therebetween is crooked, and the sealing 116a that the check-valves part 322b of bobbin 322 may be operably coupled to is formed on the pars intermedia office.Be referred to as operating room's wing passage with sealing 116a with at an end of the inlet 116 at floss hole 115 places, and the other end of sealing 116a and inlet 116 is referred to as the high-pressure side passage.The wing passage 116b of operating room forms in substrate 112a, so that tilt about floss hole 115.

The floss hole valve gear comprises drain valve 117a, retainer 117b and bolt 117c, and its structure is identical with first embodiment.

Inlet valve device 300 comprises bobbin type valve body 322, the 322b of check-valves portion and the protuberance 322c with sliding part 322a.Sliding part 322a is the main part of valve body 322, and is forming cylindricality to end thereafter, so that form cylindrical space.Make that the external diameter of slipper 322a is bigger than the external diameter of the other parts (check-valves part 322b and protuberance 322c) of valve body 322.Check-valves part 322b is formed on the position near the forward end of valve body 322, and forms the round flange shape.Protuberance 322c forms at the forward end of valve body 322, and forms cylindricality, makes its external diameter littler than the external diameter of check-valves 322b.Make the cube volume cube volume of operating room's wing passage 116b no better than of protuberance 322c.Sliding part 322a, the 322b of check-valves portion and the coaxial setting of protuberance 322c.

Cylindrical space forms in the substrate 112a of fixing spool 112, and coaxial with the wing passage 116b of operating room.The outer end of cylindrical space is to the outside opening of fluid machinery 100B.Seal 324 is arranged on the peripheral part of sliding part 322a.Valve body 322 is slidingly arranged in the cylindrical space, makes protuberance 322c in the face of the wing passage 116b of operating room.The outer end of cylindrical space is sealed by stopper spare 323, and forms pressure chamber 326, back by the space that sliding part 322a and stopper spare 323 limit.The cylindricality guide part 323a that extends towards sliding part 322a is formed on stopper spare 323 places, wherein makes the external diameter of guide part 323a less than the external diameter of stopper spare 323.Under check-valves part 323a and sealing 116a state of contact, between sliding part 322a and stopper spare 323, form the gap, thereby can move axially valve body 322.

It is distolateral that high-pressure side passage 116c is positioned at the forward direction of sliding part 322a, distolateral thereby the high pressure P 1 of the cold-producing medium in the hyperbaric chamber 114 always is applied to the forward direction of sliding part 322a.Gas spout 327 forms in substrate 112a, is used to make the back to press chamber 326 to be communicated with the 117j of pressure controling chamber (Figure 10), so that the pressure P 2 of the cold-producing medium among the 117j of pressure controling chamber is applied to pressure chamber 326, back, that is, is applied to the back to side of sliding part 322a.

Spring 325 is arranged between sliding part 322a and the stopper spare 323, and is guided by cylindricality guide part 323a.Thereby biasing force F is applied to valve body 322 on the valve closing direction,, enters the mouth 116 thereby close so that the 322b of check-valves portion contacts with sealing 116a.Biasing force F is designed to such valve, even in the V of operating room, producing high pressure during the compact model of inflate compression machine 110, and when this high pressure is applied to the protuberance 322c of valve body 322 by floss hole 115, at described valve place, valve body 322 can not move towards stopper spare 323 (opening on the direction at valve) yet.

Axial length and the external diameter of protuberance 322c design like this, make the cube volume of the protuberance 322c cube volume of operating room's wing passage 116b no better than that becomes.More specifically, the axial length of protuberance 322c designs like this, makes to open on the direction when mobile at valve when valve body 322, and protuberance 322c pulls out fully from the wing passage 116b of operating room.And protuberance 322c separates with sealing 116a, and to form circular flow channel between protuberance 322c and sealing 116a, wherein circular flow channel has the flow area that the cold-producing medium that allows necessary amount can flow through circular flow channel.As mentioned above, the mobile range of valve body 322 is designed to, make when valve body is mobile on the valve closing direction, protuberance 322c is contained among the wing passage 116b of operating room, and open on the direction when mobile at valve when valve body 322, protuberance 322c pulls out fully from the wing passage 116b of operating room, and separates with sealing 116a, to form gap (circular flow channel).

Operation control part 410 is controlled the handover operation (opening or closing) of corresponding (six) switching device shifter 420a to 420f of switching part 420 according to the command signal of coming autonomous ECU401, thereby controls the rotating speed of dynamotor 120 by the electric power (electric current and/or voltage) that is controlled at dynamotor 120 places.When dynamotor 120 work, the operation control part 410 outputs signal relevant with electric current, voltage and/or rotating speed arrives main ECU401.

Operation with explanation the 9th embodiment.When Vehicular occupant needed cooling down operation, compressor set 110 was connected with engine 10 via pulley gear 35a, made compressor set 110 be driven by engine 10.Under the situation that power operation stops temporarily, electric power is supplied with dynamotor 120, with the generation revolving force, thereby compressor set 110 is driven by compressor set 110.

When the operation as the inflate compression machine 110 of compressor set began, compressed cold-producing medium circulated in kind of refrigeration cycle 30, to carry out cooling down operation.

When compressor set 110 by from the drive force of engine 10 time, dynamotor 120 is also driven by motor driven power, to produce electric power, these electric power will be charged into battery 13.

In above-mentioned cooling down operation, the operation of liquid pump 130a stops, and switch valve 44 is opened, and three-way valve 21 switches to the position of hot water bypass mode, wherein in described hot water bypass mode, prevents to flow into heater 43 from the hot water of engine 10.Magnetic valve 117h closes, to close inlet 116.

Under the situation that does not need cooling down operation and existence from fully many used heat of engine 10, for example, the temperature that is detected by temperature sensor 15 is higher than predetermined value, fluid machinery 100F disconnects from engine 10, or the operation by dynamotor 120 stops as the operation of the fluid machinery 100F of compressor set 110.

Switch valve 44 is opened, and three-way valve 21 switches to the another location, flows into heater 43 so that allow from the hot water of engine 10.

The operation of liquid pump 130a begins, and will supply with the pressure of the cold-producing medium of heater 43 from gas-liquid separator 32 to improve.At this moment, inlet 116 still is in its closed position by valve body 117d, and cold-producing medium can be from the hyperbaric chamber 114 flow into operating rooms.Therefore, the pressure of cold-producing medium increases fast by the operation of liquid pump 130a.

Dynamotor 120 to rotate, begins its operations thereby drive removable spool 113 as electric motor operated on the direction opposite with compact model.The rotating speed of removable spool 113 is brought up to predetermined speed by the driving force of dynamotor 120.Then, magnetic valve 117h opens, and enters the mouth 116 to open, thereby 110 beginnings of inflate compression machine are as expansion gear work.

When obtaining the stable operation of rankine cycle 40, removable spool 113 rotates by the expansion of superheated refrigerant, with the output revolving force.Dynamotor 120 is the revolving force rotation by obtaining at expansion gear 110 then, and to produce electric power, these electric power will be charged into battery 13.

According to the rotating speed of the temperature of thermo-motor cooling water control inflate compression machine 110 (removable spools 113), so that can obtain maximum power in the operating period of rankine cycle 40.The temperature that flows through the cold-producing medium of heater 43 is determined by the temperature of hot water.By improving the rotating speed of dynamotor 120, can reduce the pressure of cold-producing medium, thereby improve the speed of expansion of cold-producing medium, and, can increase the pressure of cold-producing medium, thereby reduce speed of expansion by reducing the rotating speed of dynamotor 120.Therefore, obtain effective expansion work at expansion gear 110, and keep the operation balance of rankine cycle 40, thereby the cold-producing medium that will have certain degree of superheat after expansion is supplied with condenser 31.As mentioned above, can obtain higher power.

According to the 9th embodiment, when the operation of dynamotor 120 becomes uncontrollable, force to stop the operation of rankine cycle 40, the result, in the operating period of rankine cycle 40, its normal running is left in the operation of dynamotor 120.To further specify this operation referring to the flow chart of Figure 35 and the timetable of Figure 36 A to 36D.

At step S100, the operation of beginning rankine cycle 40, and in the normal control of step S110 execution to the operation of dynamotor 120.At step S120, electronic control unit 400 determines whether the operation of dynamotor 120 is in its normal condition, that is, whether the operation of dynamotor 120 leaves its normal running.

Whether definitely normally carry out the operation of dynamotor 120 according to current signal.That is, when dynamotor 120 when the electric current of its operating period is in predeterminated target current range (leaving shown in Figure 36 A definite scope), electronic control unit 400 determines that the operation of dynamotor 120 is in its normal condition.On the other hand, determine that when electric current was not within the target current scope, the operation of dynamotor 120 was in its normal condition.Being defined as under the situation not in step S120, that is, when the operation of dynamotor 120 was in its normal condition, process was got back to step S110, continued on for the normal control of the operation of dynamotor 120.Under the situation that being defined as in step S120 is, that is, in operation just often, process forwards step S130 to, stops the operation of liquid pump 130a.

At step S130, the operation of liquid pump 130a stops immediately.At step S140, whole switching device shifter 420a to 420f of switching part 420 at first close, and then three switching device shifter 420d to 420f on the ground connection side of battery 13 open, as shown in Figure 36 A.At step S150, the magnetic valve 117h of inflate compression machine 110 closes, to close inlet 116 by valve body 117d, as shown in Figure 36 C.

As mentioned above, owing to stopping of liquid pump 130a, the circulation of the cold-producing medium in the rankine cycle 40 stops, thereby the cold-producing medium of supplying with inflate compression machine 110 reduces.Three switching device shifter 420d to 420f of ground connection side open, and being formed for the closed circuit of each winding U, V and W, thereby allow electric current to flow through closed circuit.As a result, produce electrodynamic power at dynamotor 120 places, to stop the rotation of dynamotor 120 fast, as shown in Figure 36 D.Then, inlet 116 is closed by valve body 117D, flows into expansion gear 110 to stop cold-producing medium fully, as shown in Figure 36 C.

As mentioned above, when the operation of leaving its normal running and being used for dynamotor 120 in the operation of the control that is used for dynamotor 120 becomes uncontrollable, can stop the operation of inflate compression machine 110 and dynamotor 120 safely.

That is, the result as preventing that inflate compression machine 110 from quickening can avoid may damaging of fluid machinery, and this rotating speed that can occur in fluid machinery surpasses when being scheduled to allow limit.And, can suppress the generation of noise, this may anti-locking mechanism 119 work of rotation when not being fine removable and fixedly produce between the spool.Owing to the rotation that electrodynamic power is used for stopping fast fluid machinery, so compare with the fluid machinery that wherein adopts mechanical braking power, the cost of described fluid machinery becomes lower.

For whether the operation of determining dynamotor 120 is in its normal operating conditions, can be used for the voltage of fluid machinery or the signal of rotating speed at step S120, rather than electric current.

Execution in step S130 to S150 when abnormal conditions take place is to stop the operation of rankine cycle 40.Yet only one of them of execution in step S130 (stopping liquid pump 130a), S140 (turning off all switching device shifters, then device for opening 420d to 420f) and S150 (closing inlet by valve body) stops the operation of rankine cycle 40.

As the modification of the fluid machinery that is used for the 9th embodiment, can remove electromagnetic clutch 35c from fluid machinery 100F, as shown in Figure 37.According to this structure (fluid machinery 100G), when inflate compression machine 110 during as compressor device works, it is always driven by dynamotor 120.

The fluid machinery that can be used as the 9th embodiment with regard to the fluid machinery 100 and the 100A to 100D of first to the 5th embodiment explanation.

Figure 38 and 39 illustrates another modification of the 9th embodiment, has wherein revised the electrodynamic circuit that is used for dynamotor 120.

According to described modification, as shown in Figure 38, electrodynamic circuit 125 with resistance 125a and switching device shifter 125b is arranged between two the winding U and V of stator 122, operationally to form closed circuit by winding U and V, resistance 125a and switching device shifter 125b.

As shown in Figure 39, when detecting the abnormal work situation of dynamotor 120 at step S120, after the operation that stops liquid pump 130a, switching device shifter 125b closes at step S141.

As a result, electric current flows through the closed circuit of winding U and V and resistance 125a, is used for the electrodynamic power of dynamotor 120 with generation.

Depend on the circumstances, can remove step S150 from the process shown in Figure 39.
