Demand to low temperature environment, and traditional single stage vapor compression refrigeration system, under lower evaporating temperature, system COP is lower,
Inefficiency.
Utility model content
The purpose of this utility model is to design and build a kind of experimental bench of convenient and efficient to study the quasi- twin-stage of steam injection
Performance of refrigerant systems simultaneously can compare research with single-stage vapor compression refrigeration system.
A kind of quasi- double-stage compressive refrigerating system experimental bench of steam jet ejector, the experimental bench includes: evaporator, gas injection
Device, compressor, oil eliminator, condenser, liquid storage device, device for drying and filtering, heating power expansion valve, volume flowmeter one, volume flow

Connect volume flowmeter one, gas ejector, check valve two, volume flowmeter two；Oil eliminator passes through setting manual modulation valve
The nozzle of piping connection gas ejector.
The oil eliminator oil outlet connect compressor.
The utility model has following technical effect that
1, this experimental bench can realize that single-stage vapor compression formula refrigeration cycle and steam injection are quasi- double by the switch of valve
Two kinds of methods of operation of grade compression refrigeration cycle, and the variation of cooling system amount and system performance is carried out in fact under different operating conditions
Test research.
2, steam, which sprays quasi- Two-stage refrigerating system, can obtain evaporating temperature more lower than single-stage vapor compression refrigeration system,
And under lower evaporating temperature, steam sprays quasi- Two-stage refrigerating system performance and is better than single-stage vapor compression refrigeration system.
Detailed description of the invention
Fig. 1 is a kind of quasi- double-stage compressive refrigerating system experimental bench schematic diagram of steam jet ejector.
Specific embodiment
System is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that described herein
Specific embodiment is only used to explain this system, is not used to limit this system.
Such as Fig. 1, a kind of quasi- double-stage compressive refrigerating system experimental bench of steam jet ejector, comprising: evaporator 1, gas ejector
2, compressor 3, oil eliminator 4, condenser 5, liquid storage device 6, device for drying and filtering 7, heating power expansion valve 8, one M1 of volume flowmeter, body
Product two M2 of flowmeter, one Z1 of check valve, two Z2 of check valve, one F1 of ball valve, two F2 of ball valve, solenoid valve F3, manual modulation valve F4；It steams
Hair device refrigerant outlet is separately connected one F1 of ball valve, two F2 of ball valve；One F1 of ball valve is sequentially connected one Z1 of check valve, body by pipeline
Product two M2 of flowmeter, compressor, oil eliminator, condenser, liquid storage device, device for drying and filtering, solenoid valve F3, heating power expansion valve, steaming
Device refrigerant inlet is sent out, two F2 of ball valve passes through one M1 of piping connection volume flowmeter, gas ejector 2, two Z2 of check valve, volume
Two M2 of flowmeter；The nozzle that oil eliminator 4 passes through the piping connection gas ejector 2 of setting manual modulation valve F4.
Two F2 of ball valve, manual modulation valve F4 are closed, and are single-stage vapor compression formula refrigeration system when one F1 of ball valve is opened, by
Evaporator, compressor, oil eliminator, condenser, liquid storage device, device for drying and filtering, heating power expansion valve and other auxiliary devices composition.
The liquid refrigerant becomes the heat realization that refrigerant gas absorbs object to be cooled after evaporating in evaporator
Refrigeration.
The refrigerant gas is compressed within the compressor, after increasing temperature and pressure, in oil eliminator after sedimentation separation compression
Refrigerant vapour in lubricating oil, the temperature refrigerant vapor condensation that oil eliminator is discharged condenser becomes saturated liquid,
Enter heating power expansion valve reducing pressure by regulating flow by liquid storage device, device for drying and filtering, solenoid valve etc., the refrigerant temperature after throttling also declines
To evaporating temperature, and part flash steam is generated, liquid mixture enters evaporator and is evaporated, and repeats the above process；
Two F2 of ball valve, manual modulation valve F4 are opened, and when one F1 of ball valve is closed, spray quasi- two-stage compression refrigeration for steam
System.Gas ejector suction carrys out the refrigeration working medium of flash-pot, is sent into compressor air suction mouth after improving its pressure.Compressor is taken out
The refrigerant vapour from gas ejector is inhaled, is compressed to condensing pressure within the compressor；
The compressor air-discharging is divided into two parts by oil eliminator: power of a part as gas ejector is sent into
To the nozzle of injector, vapor refrigerant is converted into kinetic energy by pressure energy in nozzle, and suction chamber is made to form low-pressure area, and suction comes
The low pressure refrigerant vapor of flash-pot；Another part enters condenser, after completing cooling, condensation, by heating power expansion valve
It is throttled to evaporating pressure, cooling capacity is produced in evaporation in evaporator, is cooled down to freezer, is then repeated above-mentioned process of refrigerastion.
The above is only the preferred embodiment of this patent, it is noted that for the common skill of the art
For art personnel, under the premise of not departing from this system principle, several improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as the protection scope of this patent.
