Specific embodiment
Below in conjunction with drawings and Examples, technical scheme is described in further detail.
As shown in figure 1, the pipeline composition schematic diagram for vaporizer first embodiment of the present invention.Wherein, 50 is vaporizer, steams
The refrigerant passage sending out device 50 is round copper pipe, and empty circles 510 are refrigeration pipings, and solid circles 520 are defrosting pipelines.
As shown in Fig. 2 the pipeline connection diagram for vaporizer first embodiment of the present invention.
Wherein, the flow direction of low-temp low-pressure coolant when hollow arrow represents vaporizer 50 refrigeration, now coolant is along hachure
Tube runs, the coolant of low-temp low-pressure is out divided into 4 tunnels through separating tube 1,2,3,4 afterwards respectively from low pressure inlet house steward 511, then
Enter in the refrigeration piping 510 of vaporizer 50, the refrigeration piping 510 of vaporizer 50 is also classified into 4 tunnels, and there are 6 copper pipes on each road, cold
Matchmaker, after 4 road refrigeration piping outputs, enters in suction nozzle 512 together, then flows to compressor.
The flow direction of high pressure refrigerant when filled arrows represent vaporizer 50 defrosting, now coolant is along broad-brush tube runs,
High pressure refrigerant is divided into two-way after high-pressure inlet house steward 521 output, respectively enters the two-way pipeline of vaporizer 50 defrosting pipeline 520
In, also enter back into through the water accumulating disc defrosing pipe 526 of vaporizer 50 bottom setting after the two-way pipeline output of defrosting pipeline 520
In high-pressure liquid tube 522, and export from high-pressure liquid tube 522.
As shown in figure 3, the theory of constitution schematic diagram for inventive refrigeration system first embodiment.Wherein, 10 is compressor,
61 is four-way change-over valve, and 20 is condenser, and 30 is two-way reservoir, and 50 is vaporizer, and vaporizer 50 comprises refrigeration piping 510 He
Defrosting pipeline 520, it is gas-liquid separator that the bottom of vaporizer 50 is additionally provided with water accumulating disc defrosing pipe 526,62, and 40 and 66 are heat
Power expansion valve, 63 is break-make electromagnetic valve, and 64 and 65 are check valve, and its conducting direction is direction shown in arrow.
Four-way change-over valve 61 is an electromagnetic valve, total d mouth, e mouth, s mouth, four connectors of c mouth, and has two operations
Position, during four-way change-over valve 61 power-off, its d mouth connects with c mouth and e mouth connects with s mouth, on four-way change-over valve 61 during electricity, its d mouth
Connect with e mouth and c mouth connects with s mouth.
The d mouth of four-way change-over valve 61 is connected with the air vent of described compressor 11, and the s mouth of four-way change-over valve 61 is through gas-liquid
Separator 62 is connected with the air entry of compressor 11, and the c mouth of four-way change-over valve 61 is sequentially connected in series connection condenser to e mouth
20th, the defrosting pipeline 520 of check valve 65, reservoir 30, check valve 64, water accumulating disc defrosing pipe 526, vaporizer 50, check valve 65
Two ends be also arranged in parallel heating power expansion valve 66, on the connecting pipe between reservoir 30 and check valve 64 also bypass have one
Pipeline, this pipeline connects gas-liquid separation after sequentially passing through the refrigeration piping 510 of electromagnetic valve 63, heating power expansion valve 40, vaporizer 50
The entrance of device 62.In the refrigeration system application of the present embodiment and low temperature miniature cold storage, condenser 20 and vaporizer 50 are all using wind
Cold.
During cooling system, four-way change-over valve 61 power-off, electromagnetic valve 63 is opened, and the cold-producing medium of High Temperature High Pressure is defeated from compressor 10
After going out, sequentially pass through the d mouth of four-way change-over valve 61 and c mouth enters condenser 20, after radiating condensation in condenser 20, become high
Press liquid, be then passed through check valve 65 enter reservoir 30, from reservoir 30 output high-pressure liquid coolant through electromagnetic valve 63
Enter heating power expansion valve 40 afterwards to throttle, be changed into the biphase coolant of low-temp low-pressure, subsequently in the refrigeration piping 510 of vaporizer 50
Heat absorption is changed into low-pressure gas, is then passed through the air entry that gas-liquid separator 62 returns to compressor 11, forms a complete refrigeration
Circulation.
With the increase of cooling system time, the frost layer of vaporizer 50 fin surface increasingly thicker therefore, it is desirable to evaporation
Device 50 defrosts.
During system defrosting, electricity on four-way change-over valve 61, electromagnetic valve 63 cuts out, and the cold-producing medium of High Temperature High Pressure is defeated from compressor 10
After going out, sequentially pass through the d mouth of four-way change-over valve 61 and e mouth enter the defrosting pipeline 520 of vaporizer 50, radiating condensation wherein,
The water accumulating disc defrosting pipe 526 entering back into vaporizer 50 bottom radiates further and is changed into highly pressurised liquid, is then passed through check valve 64 and enters
Enter in reservoir 30, be changed into the two of low-temp low-pressure from the high-pressure liquid coolant of reservoir 30 output after heating power expansion valve 66 throttling
Phase coolant, entering back into the heat of vaporization absorbing in surrounding air in condenser 20 becomes low-pressure gaseous coolant, then in turn through
The c mouth of four-way change-over valve 61, s mouth and gas-liquid separator 62, eventually pass back to the air entry of compressor 11, complete complete removing
Frost circulation.
In defrosting circulation, the coolant in vaporizer 50 refrigeration piping 510 is heated and is inhaled into through gas-liquid separator 62
The air entry of compressor 10, in the system hence into defrosting circulation.After the completion of defrosting circulation, when just starting kind of refrigeration cycle, steam
Send out the device 50 slightly higher coolant of pressure in pipeline 520 that defrosts and sequentially pass through the e mouth of four-way change-over valve 61, s mouth, gas-liquid separator 62,
It is inhaled into the air entry of compressor 10, hence in the system of kind of refrigeration cycle.
Because the ad hoc defrosting pipeline 520 of vaporizer 50 and its internal volume and heat exchange area are relatively small, to vaporizer 50
During defrosting, the coolant of needs less and also defrost pressure will not too low so that impact system or compressor normally run, during defrosting,
Due to being provided with reservoir 30, the coolant of water accumulating disc defrosting pipe 526 output from vaporizer 50 bottom does not almost have degree of supercooling, steams
Send out in the defrosting pipeline 520 and water accumulating disc defrosting pipeline 526 of device 50, remove the sub-fraction that discharge superheat coolant takies pipeline,
It is condensation temperature, during defrosting, system operation is reliable, and defrost uniformly, quickly, thoroughly, efficiently.
Finally it should be noted that: the foregoing is only the preferred embodiments of the present invention, be not limited to this
Bright, for a person skilled in the art, the present invention can have various modifications and variations.So, all spirit in the present invention
With any modification made within principle, equivalence replacement, improvement etc., should be included within the protection domain of present invention request.
