For those of ordinary skill, above-mentioned term concrete meaning in the present invention can be understood as the case may be.
Below with reference to Fig. 1, refrigerating plant 100 according to embodiments of the present invention is described.
As it is shown in figure 1, refrigerating plant 100 according to embodiments of the present invention, including: compressor assembly 1, condenser 2, first
Vaporizer 3, flash vessel 5 and the second vaporizer 6.Wherein compressor assembly 1 includes the first cylinder 10 and the second cylinder 11, the first gas
Cylinder 10 has the first air entry and first row QI KOU, and the second cylinder 11 has the second air entry and second exhaust port.In the present invention
Some concrete examples in, the first cylinder 10 and the second cylinder 11 are located in same housing, say, that compressor assembly 1
Including a compressor, the first cylinder 10 and two cylinders that the second cylinder 11 is same compressor.At another of the present invention
In a little concrete examples, compressor assembly 1 includes that two compressors, the first cylinder 10 and the second cylinder 11 are respectively two compressors
Cylinder, say, that compressor assembly 1 includes two single cylinder compressors, and the limiting cylinder of two compressors makes the first cylinder
10 and second cylinder 11.
First end of condenser 2 connects with first row QI KOU and second exhaust port respectively.First end of the first vaporizer 3 with
Being in series with first throttle element 4 between second end of condenser 2, first throttle element 4 plays the effect of reducing pressure by regulating flow, optional
Ground, first throttle element 4 is capillary tube, electric expansion valve or heating power expansion valve.Of course, it should be understood that first throttle is first
The element that part 4 can also have reducing pressure by regulating flow effect for other, such as, can be restriction sleeve.
Flash vessel 5 is provided with inlet tube 50, drain pipe 51 and escape pipe 52, and flash vessel 5 can play the effect of gas-liquid separation,
Inlet tube 50 is connected with the second end of the first vaporizer 3, and escape pipe 52 is connected with the first air entry.The first of second vaporizer 6
It is in series with second section fluid element 7, the second end of the second vaporizer 6 and the second air entry between end and drain pipe 51 to be connected.Wherein
Second section fluid element 7 plays the effect of reducing pressure by regulating flow, and alternatively, second section fluid element 7 is capillary tube, electric expansion valve or heat
Power expansion valve.Of course, it should be understood that second section fluid element 7 can also have the element of reducing pressure by regulating flow effect, example for other
As being restriction sleeve.
As illustrated by the arrows in fig. 1, the High Temperature High Pressure coolant discharged from first row QI KOU and second exhaust port enters condensation
In device 2, subcooled liquid is dispelled the heat in condensation, and subcooled liquid enters in the first vaporizer 3 after first throttle element 4 decrease temperature and pressure
Becoming gas-liquid mixture after absorbing heat, gas-liquid mixture through flash vessel 5 and carries out gas-liquid separation in flash vessel 5 afterwards.
The gaseous coolant separated enters into the first air entry by escape pipe 52 and is compressed into high temperature and high pressure gas by the first cylinder 10；
The liquid refrigerants separated enters the second vaporizer 6 by drain pipe 51, second section fluid element 7 respectively and absorbs after heat by the
Two air entries suck, and these coolant sucked by the second air entry are compressed into high temperature and high pressure gas in the second cylinder 11.From
The high temperature and high pressure gas that first cylinder 10 and the second cylinder 11 are discharged all enters into condenser 2, the most repeatedly.
It follows that the pressure of the coolant of the second air entry absorption of the first air entry of the first cylinder 10 and the second cylinder 11
Power is different, and the coolant discharged from the first vaporizer 3 is flashed device 5 gas-liquid separation, and the liquid refrigerants separated is through second section
The reducing pressure by regulating flow heel row of fluid element 7 is to the second vaporizer 6, and the gaseous coolant separated is pressed in being drained into the first cylinder 10
Contracting, such that it is able to the gaseous coolant content in reducing the coolant flowing into the second vaporizer 6, the gaseous state simultaneously discharged from flash vessel 5
The coolant pressure of coolant, more than the evaporating pressure of the second vaporizer 6, can reduce compression ratio and compressor horsepower is declined.
Refrigerating plant 100 according to embodiments of the present invention, increases a flash vessel 5 by the entrance at the second vaporizer 6,
Gaseous coolant is separated, the heat exchange efficiency of the second vaporizer 6 not only can be made to improve, it is also possible to minimizing is separated
The work done during compression of gaseous coolant, thus improve the heat exchange amount of refrigerating plant 100, reduce compressor horsepower.
In a preferred embodiment of the invention, the first cylinder 10 is different with the delivery space of the second cylinder 11.The most excellent
Selection of land, the delivery space of the first cylinder 10 is less than the delivery space of the second cylinder 11.Of course, it should be understood that in order to reduce zero
The delivery space of the kind of parts, the first cylinder 10 and the second cylinder 11 can also be identical.
As it is shown in figure 1, according to some embodiments of the present invention, refrigerating plant 100 also includes the first reservoir 8, the first storage
Liquid device 8 is located between the second air entry and the second vaporizer 6, and the first reservoir 8 can play the effect of gas-liquid separation, from second
The coolant that vaporizer 6 is discharged is drained in the first reservoir 8 and carries out gas-liquid separation, and the gas coolant separated is from the second air-breathing
Mouth is compressed, such that it is able to avoid the second cylinder 11 that liquid hit phenomenon occurs in being drained into the second cylinder 11.
In some embodiments of the invention, refrigerating plant 100 also includes the second reservoir (not shown), the second liquid storage
Device is located between the first air entry and escape pipe 52, and the second reservoir plays the effect of gas-liquid separation, discharges from escape pipe 52
Coolant is drained into the first gas through the second time gas-liquid separation of the second reservoir, the gaseous coolant separated from the first air entry
It is compressed in cylinder 10, such that it is able to avoid the first cylinder 10 that liquid hit phenomenon occurs further.
In the present invention, unless otherwise clearly defined and limited, fisrt feature second feature " on " or D score permissible
It is that the first and second features directly contact, or the first and second features are by intermediary mediate contact.And, fisrt feature exists
