The utility model discloses an adopt the binary channels refrigeration in cryogenic refrigerating system, solved the inside problem of frosting easily of the evaporimeter under the low temperature. Have advantages such as simple structure, convenient operation, solution frost problem.
Description
Technical field
The present invention relates to dual pathways cascade refrigeration system, belongs to refrigerating field.
Background technology
Traditional single refrigeration system, is conditional to cryogenic temperature, cannot meet most of worst cold case, multiple
The appearance of stacked Refrigeration Technique solves this problem, it is possible to achieve -80 ° of even lower cryogenic temperatures.
Cascade refrigeration technology realizes the increasingly lower requirement of cryogenic temperature, but due to cryogenic temperature mistake in vaporizer
It is low, easily cause frosting, or even icing, the whole vaporizer of serious blocking, safety, efficiency for vaporizer etc. all to have greatly
Affect, be very important problem.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of simple structure, it is easy to operate, can be with
The double pass system of defrosting process is carried out to vaporizer.In the case that the processing meanss can ensure that refrigeration system is normally run,
Vaporizer to bypassing carries out defrosting process, realizes that two-way sweat cooling system is used alternatingly, has ensured stablizing for refrigeration system
Operation.
The present invention for achieving the above object, is adopted the following technical scheme that：
A kind of novel double-channel cascade refrigeration system, is divided into high temperature and cryogenic refrigerating system, including vaporizer, compressor,
Condenser, choke valve, gas-liquid separator, oil eliminator and valve, wherein described one-level vaporizer belong to high-temperature refrigeration system,
Secondary evaporimeter a and secondary evaporimeter b belong to cryogenic refrigerating system, and vaporizer a and vaporizer b take turns to operate, by valve A and
The switch of valve B is controlled.
Described refrigeration system is divided into high temperature and low temperature, belongs to two grades of cascade refrigerations.
Described refrigeration system includes vaporizer, compressor, condenser, choke valve, gas-liquid separator, oil eliminator and valve
Door.
Described one-level vaporizer belongs to high-temperature refrigeration system.
Described secondary evaporimeter a and b belongs to cryogenic refrigerating system, and vaporizer a and b take turns to operate, by valve A and B
Switch be controlled.
Two-way secondary evaporimeter system of the dual pathways defrosting device of the present invention using parallel connection, when using secondary evaporimeter a's
When refrigeration system is normally run, enter in secondary evaporimeter b from compressor part high temperature and high pressure steam out, carry out defrosting
Process.After defrosting process terminates in secondary evaporimeter b, the operation of secondary evaporimeter b refrigeration systems is switched to, to secondary evaporimeter
A carries out defrosting process, alternately, it is ensured that the stability of system operation.
Numerous valves is for the operating loop for controlling refrigeration system, it is ensured that the normal operation of system.
Compared with prior art, it is an advantage of the invention that：Simple structure, easy to operate, bypass defrosting is processed.
Description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
A kind of novel double-channel cascade refrigeration system as shown in Figure 1, mainly by one-level vaporizer 1, gas-liquid separator 2,
Compressor 3, gs-oil separator 4, condenser 5, choke valve 6, secondary evaporimeter a7, secondary evaporimeter b8, valve A and valve B groups
Into.
Cold-producing medium is flowed out from vaporizer, through gas-liquid separator, compressor, gs-oil separator, condenser, choke valve, most
Again vaporizer is flowed back to afterwards.Material to be cooled carries out high-temperature refrigeration into one-level vaporizer, enters subsequently into secondary evaporimeter
Row cryogenic refrigeration.When into secondary evaporimeter a, all of valve A is opened, and valve B is closed.Refrigeration in two-stage system cooling system
Gas-liquid separator, compressor and gs-oil separator are flow through in agent, and part of refrigerant enters condenser, then through choke valve, flows into
Vaporizer, completes circulation；The cold-producing medium of another part High Temperature High Pressure out enters secondary evaporimeter b afterwards from gs-oil separator,
Defrosting process is carried out, the cold-producing medium after the completion of process flows back to condenser again again, complete circulation.When whole secondary evaporimeter b melts
After the completion of frost, then refrigeration system is switched over.All valve A are closed, and valve B is opened.Secondary evaporimeter b is normally made
SAPMAC method, secondary evaporimeter a carry out defrosting process.So circulate, alternate run.
The present invention is by using two passway system cooling system, solving the problems, such as cryogenic vaporizer frosting, it is ensured that refrigeration system
The normal operation of system, reduces cost.
Advantage of the invention is that simple structure, easy to operate, reduces cost and frosting is solved the problems, such as.
