Specific embodiment
First, it should be appreciated that according to technical literature, vaporizer " can run (power) " form according to it and classify, i.e.
Vaporizer can be defined to dry expansion vaporizer, flooded evaporator or liquid oversupply vaporizer.
Dry expansion vaporizer usually " is supplied " previous turbulent flow refrigerant fluid (liquid and steam) and in its outflow
In mouthful, all cold-producing mediums are in superheated steam form.Flooded evaporator generally " supply " is in only the cold-producing medium of liquid form, full
Solution type evaporator equipped at outlet port, all cold-producing mediums are in that saturated vapor fluid form is dried.
This arrangement is important, because the refrigeration system of currently proposed inclusion at least two parallel evaporator is specifically
Be shaped to provide the dry expansion vaporizer in parallel with flooded evaporator, and vaporizer " supply " have no effect on another
The " RUN " of vaporizer.
As shown in figure 3, according to the present invention, the refrigeration system including the vaporizer of at least two parallel connections mainly includes compressor
1st, condenser 2, switching device 3,41, second expansion gear 42 of one first expansion gear, dry expansion vaporizer 51, full liquid
Formula vaporizer 52 and liquid accumulator device 6.
Compressor 1 is substantially Conventional press, including single flow export 11 and single suction path 12.
Condenser 2 is substantially conventional vessel, and it includes ingress path 21 and flow export 22.
Switching device 3 is any device, and it includes ingress path 31 and at least two flow exports 32 and 33, can switch it and enter
The fluid communication of the only one in mouth path 31 and at least two flow exports 32 or 33.Preferably, described switching device 3 is substantially
It is the conventional three-way valve for two positions.
First expansion gear 41 and the second expansion gear 42 are all traditional expansion device, and preferably, are this area skills
Conventional capillaries known to art personnel.
Vaporizer as cooling chamber (not shown) or the dry expansion vaporizer as high pressure and cryogenic vaporizer
51 is that traditional drying expands vaporizer, and it consists essentially of ingress path 511 and flow export 512.
Vaporizer as freezing chamber (not shown), i.e. the flooded evaporator as low pressure and very cryogenic vaporizer
52, it is conventional flooded evaporator, it includes ingress path 521 and flow export 522.
And liquid accumulator device 6 is the liquid accumulator device being routinely used in refrigeration system, and include airtight housing, this gas
Close housing is provided through at least one entrance, at least one upper inlet path 62 and the flow export 63 at least one of bottom 61.
According to the present invention, the flow export 11 leading to compressor 1 is fluidly connected to the ingress path 21 leading to condenser 2.
The flow export 22 of condenser 2 is fluidly connected to the entrance 31 of switching device 3.
The flow export 32 of switching device 3 is fluidly connected to the first expansion gear 41, and the first expansion gear 41 is connected to logical
Ingress path 511 to dry expansion vaporizer 51.The flow export 512 of described dry expansion vaporizer 51 is fluidly connected to liquid
The upper inlet path 62 of body accumulator 6.
The flow export 33 of switching device 3 is fluidly connected to the second expansion gear 42, and the second expansion gear 42 is via input
Mouth 521 is connected to flooded evaporator 52.The flow export 522 of aforementioned flooded evaporator 52 is fluidly connected to liquid accumulator device
6 bottom inlet path 61.
And the upper flow export 63 of liquid accumulator device 6 is fluidly connected to the suction path 12 of compressor 1.
It is noted that fluidly connecting between system element as described above is come by conventional metals pipe device
Execution.
Based on the arrangement of above-detailed, demonstrate the final two kinds of functions of execution simultaneously of liquid accumulator device 6, comprising: i)
Attachment means between the flow export 512 of vaporizer 51 and 52 and 522 and the suction path 12 of compressor 1;And, ii)
Adiabatic apparatus between the evaporation pipeline of the evaporation pipeline of dry expansion vaporizer 51 and flooded evaporator 52.
In view of liquid accumulator device 6 serves as link between vaporizer 51 and 52 and compressor 1 it is clear that the present invention is easy to
Overall this system of over-assemble (referring to Fig. 2).
Liquid tank 6 is served as in each spacer medium evaporating between row it may be said that becoming it to be mainly responsible for maintaining evaporation pipeline
Between independence, and specifically, maintain flooded evaporator 52 to be always at full liquid condition, or even when it does not operate
(operation depending on vaporizer 51 is dried).
Therefore, when dry expansion vaporizer 51 operates (according to the ad-hoc location of switching device 3), i.e. dry when being only supplied
During dry expansion vaporizer 51, compressor 1 tends to only suck the superheated steam obtaining from described dry expansion vaporizer 51, and
Flooded evaporator 52 is still full of coolant, and wherein, liquid in tank should be in its minimum liquid level and lower inlet always expires liquid.
When flooded evaporator 52 operates (also due to ad-hoc location of switching device 3), i.e. steam when being only supplied full-liquid type
When sending out device 52, the superheated steam that compressor 1 tends to suck first from the rise of described dry expansion vaporizer 51 is self-satisfied as coming
The dry saturated steam of solution type evaporator 52, and in the second time, only sucks and saturation is dried from flooded evaporator 52
Steam, and the cold-producing medium being contained in dry expansion vaporizer 51 is completely exhausted out and is deposited in accumulator that to arrive it maximum
Value, maintains the flow export leading to compressor to be constantly filled with superheated steam simultaneously.
In other words, above-detailed operation channel syndrome make a clear distinction between right and wrong Chang Youli's it is important to notice that, liquid amass
Store device 6 and must have bigger gravitional force with respect to flooded evaporator 52, after all, maximum gravitional force is finally limited to described
Siphon effect between liquid accumulator device 6 and aforementioned flooded evaporator 52, prevents refrigerant liquid from changing position when not sucking
Put.
However, also illustrate the refrigeration system including at least two parallel evaporators as disclosed herein being also entirely capable of solely
Stand on liquid accumulator device 6 gravitional force bigger with respect to flooded evaporator 52 and operate, after all, depend on determined by system
Cold dynamic, the pressure reduction between vaporizer 51 and 52, i.e. the pressure of described dry expansion vaporizer 51 is more than flooded evaporator
52 pressure (certainly, depending on the concrete size of expansion gear 41 and 42) is enough to maintain cold-producing medium in liquid phase only in accumulator
It is liquid in 6 lower region, and be liquid therefore in whole flooded evaporator 52.
In more detail, also illustrate, preferably but and without limitation, compressor 1 substantially Conventional press, it can be
Operate in the case of there is no lubricant.Finally, also illustrate Fig. 3 and some terms expections used above illustrate that the present invention's is excellent
Select embodiment it is impossible to be understood to restricted embodiment, after all, the scope of the present invention must be understood as claim such as and solves
Release such width, the scope of the present invention also includes possible equivalent device.
