Sparger 100 has normally columnar body 102.Body 102 comprises nozzle body 104 and diffuser portion 106.Fluid tip 108 is positioned in nozzle body 104.Body 102 also comprises mixed area, and this mixed area is set to the form in zone of convergence 110 and has leaving the cross sectional area reduced on nozzle 108 direction and along the axis of sparger 100.Diffuser portion 106 also comprises radiating area 118, and this radiating area 118 has the cross sectional area increased on the direction leaving nozzle 108 and along the axis of sparger 100.
Sparger 100 has the first entrance 114 of the first fluid for receiving such as refrigeration agent and so on.In addition, sparger 100 has the second entrance 116 for receiving second fluid, and this second fluid also can be refrigeration agent.But it will be understood by those of skill in the art that, first fluid and second fluid can have various different type.Such as, first fluid and/or second fluid can be alternately air, water, water vapour or refrigerant vapor or other suitable fluid any.First fluid 114 has pressure P 1 through before nozzle 108.Nozzle 108 has radiating area 109, first fluid leaves nozzle 108 by this radiating area 109 and radiating area 109 causes the expansion of first fluid, first fluid is expansion zone of convergence 110 further, in this zone of convergence 110, first fluid has the pressure P 2 (and the speed of first fluid increases) of reduction.In the operation of sparger 100, the enough low second fluid that makes of pressure P 2 is drawn to the mixed area of zone of convergence 110 by the second entrance 116 to mix with first fluid.The mixture of first fluid and second fluid is through zone of convergence 110, cylindrical area 112, diffusion zone 118 and leave sparger 100 with pressure P 3 afterwards.Therefore, sparger 100 is as the pump of pressure increase or the compressor that make second fluid.
The efficiency of sparger 100 pumping second fluid depends on various operating parameter, and these operating parameters comprise the difference between the pressure P 1 of the given design for sparger 100, P2 and P3.Such as, be larger situation for P3 for P1, compared with the situation that P3 is less, nozzle 108 should be positioned in zone of convergence 110 further.
Nozzle 108 can move along the axis of sparger 100, and nozzle 108 can be located according to P3, P2 and P1.In this embodiment, nozzle 108 has retainer 121, and in this retainer 121, nozzle 108 is along the axial sliding movement of sparger 100.Sparger 100 also comprises around nozzle 108 and the barrier film 119 of sealed-in nozzles 108.In addition, sparger 100 comprises conduit 122, and this conduit 122 makes the end sections of diffuser region 118 be connected with the volume 123 after barrier film 119.Therefore, volume 123 has pressure proportional or roughly equal with pressure P 3 in this embodiment, make the pressure in volume 123 promote barrier film 119 and promote nozzle 108 and move to barrier film 119 by the position fully expanded to make nozzle 108, make barrier film 119 provide abundant reaction force and nozzle is positioned at adjustment position.Barrier film 119 is by certainty ratio and be arranged so that operational condition that is that this adjustment position can realize approximate desired according to P3 relative to other pressure of sparger or that at least improve.
Orifice holder 121 is provided with the device of the motion for suppressing nozzle 108, makes nozzle 108 not change position along with the rapid fluctuation of pressure P 1, P2 or P3.The rapid fluctuation of pressure can be caused by the pressure wave in sparger or shock wave.Damping can be provided by the friction in orifice holder 121.This friction can provide by comprising flexible ring 130 in orifice holder 121.
It will be understood by those of skill in the art that, sparger 100 can alternately be set to take a different form.Such as, barrier film 119 can only partly around nozzle 108 and remainder can be rigid.In addition, barrier film 119 can be positioned at other positions except Fig. 1 instruction.Such as, barrier film 119 can be positioned at sparger 100 and further along nozzle 108.In addition, barrier film 119 can provide the suitable spring mechanism (comprising such as compression or expansion spring) of reaction force to replace by being set to nozzle to be positioned at adjustment position.In this case, sparger 100 can comprise or can not comprise barrier film 119, and pressure P 3 can push the rigid walls (not shown) being attached to movable sprinklers 108, move until spring mechanism provides sufficient reaction force to make nozzle 108.In addition, retainer 116 can be set in any suitable form or can not exist.Such as, barrier film 119 or rigid walls can be arranged to keep nozzle 108.In addition, one end of conduit 122 can in zone of convergence 110 or near the outlet being positioned at nozzle 108 in cylindrical area 112.In addition, sparger 100 can comprise zone of convergence.Such as, mixed area can be incorporated in diffusion zone 118.In another modification, sparger can comprise the actuator being arranged to the position adjusting fluid tip 108 according to P1, P2 or P3.Such as, sparger can comprise pressure transducer, the change of this pressure sensor senses P1, P2 or P3 and the output signal produced for controlling actuator.

Fig. 4 illustrates the method for operation sparger according to the embodiment of the present invention.Method 400 comprises the step 402 and 404 receiving first fluid and second fluid.Method 400 also comprises and guides first fluid by the nozzle of sparger, makes the pressure of first fluid be decreased to the second pressure lower than the first pressure.Method 400 also comprises to be drawn second fluid second fluid is mixed (step 408) with the first fluid of the outlet leaving nozzle, according to the position of the mixed area relative to sparger of the outlet of the first pressure and/or the first fluid of mixing and the pressure adjusting nozzle of second fluid to improve the efficiency (step 410) of sparger.Step 408 can comprise the position of the outlet of self-regulating fluid tip.
Turn to Fig. 5 now, describe the operation of sparger 100 in heat pump refrigeration cycle in more detail.
Heat pump refrigeration cycle 500 comprises high temperature subcycle and low temperature subcycle (being 510 and 512 respectively) in this example.In high temperature subcycle 510, the heat being passed to sparger 100 by vapor generator 514 from thermal source (such as solar collector 504) causes ejector cycle working fluid to evaporate in the temperature of the saturation temperature a little more than refrigeration agent maker 514.Then, flow of vapor is to sparger 100, and at sparger 100 place, steam is by the nozzle accelerated (and pressure reduction) of sparger 100.
Pump 516 may be needed to produce pressure difference operate for sparger 100, but be compressed due to liquid, power consumpiton is relatively little.
Then, the fluid coming self-generator 514 and vaporizer 518 mixes in sparger 100 and the fluid mixture obtained stands compression shock.Like this, hot compression instead of the motor compressor in conventional heat pump.In the diffusion zone of sparger 100, there is compression further, flow into condenser 520 after making the subcritical flow occurred from sparger 100.Because the position of the outlet of the nozzle 108 of sparger 100 is adjusted (such as self-regulating), if operation pressure changes, then sparger 100 provides the efficiency of raising.
At condenser 520 place, heat discharged to surrounding environment, thus causes the refrigerant liquid of condensation from working fluid (refrigeration agent) in condenser 520 outlet port.
Then the liquid refrigerant leaving condenser 520 is divided into two plumes: a plume enters vaporizer 518 by expansion valve 552 after pressure reduces, and another plume is back in maker 514 after experiencing pressure increase by refrigerated medium pump 516.Refrigerant fluid evaporates in vaporizer 518, absorbs heat from cooled environment, and then it to be brought back to sparger 100 thus to complete circulation.
