Background technology
Cold storage development is rapid, and a large-scale freezer has different refrigerating spaces, such as 0 DEG C, -18 DEG C, -30 DEG C of storehouses
Temperature, the current Ku Wen to obtain different temperature often uses a unit or several different unit La Kuwen, when using one
Unit generally passes through valve transfer in the case where stopping to a class libraries Wen Lawen to another when drawing the storehouse temperature of different temperatures
Ku Wen carries out La Wen, or draws temperature respectively using many different units, causes that temperature fluctuation in storehouse is big, cost in this case
Height, while controlling trouble, proposes the utility model in such cases, and the utility model need not be being carried out under other operations
Two kinds of different Ku Wen can be provided, especially quick-frozen and two kinds of storehouse temperature of refrigeration.
Utility model content
The purpose of this utility model is directed to technological deficiency present in prior art, and provides a kind of band vortex tube runback
Cascade refrigeration system.
To realize that the technical scheme that the purpose of this utility model is used is：
A kind of band vortex tube auto-cascading refrigeration system, the exhaust outlet of compressor of the refrigeration system and the first condenser inlet
Connection, the outlet of first condenser is connected with vortex tube inlet, the vortex tube have cold air outlet, saturated solution export and
Heat outlet, the heat outlet of the vortex tube is connected with the second condenser inlet, the outlet of the gaseous state of second condenser with
The gaseous state entrance connection of condenser/evaporator, the liquid outlet of the second condenser pipe device after the first expansion valve with condenser/evaporator
Liquid entrance is connected, and the condenser/evaporator liquid outlet is connected after the second expansion valve with the first evaporator, the vortex tube
Saturated solution outlet is connected with the second evaporator inlet, the condenser/evaporator gaseous state outlet, the outlet of the first evaporator gaseous state, vortex
Pipe cold air outlet and the second evaporator outlet are connected after merging with the compressor air suction mouthful.
The refrigeration system is using R22 and R23 working medium.
Compared with prior art, the beneficial effects of the utility model are：
A kind of band vortex tube auto-cascading refrigeration system of the present utility model has the characteristics that：

Using R22 and R23 working medium.
In the system, R22 has different condensation temperatures from R23 working medium, and it is cold that the working substance steam after compression enters first
Condenser 2 is condensed, and condensed liquid refrigerant enters nozzle of vortex tube of the vortex tube 13 along interior tangential distribution, in minor air cell
High speed rotating separation goes out cold air, saturated solution and hot gas, and saturated solution is evaporated into the second evaporator 16, there is provided one kind evaporation temperature
Degree, can be used for freezing-cooling storeroom class, and hot gas is condensed into the second condenser 9, and now R22 is condensed, and R23 is still gas
State, condensed R22 is condensed into condenser/evaporator 3 by after the step-down of the first expansion valve 6 to R23, condensed R23 warps
Second expansion valve 5 enters the first evaporator 10 after being depressured, and now provides a kind of relatively low evaporating temperature, can be used for quick freezing repository class,
Enter after first evaporator 10, condenser/evaporator 3, vortex tube cold air outlet 15, the working substance steam mixing of the second evaporator outlet
Compressor 1 is compressed, and the mixed more general auto-cascading refrigeration system pressure of inspiration(Pi) of gaseous working medium pressure has been raised.It is described
The operation that system is so gone round and begun again.
The above is only preferred embodiment of the present utility model, it is noted that general for the art
