Having exhaustor 14, the first cylinder 11 and the second cylinder 12 to be located in housing 10, the first cylinder 11 is provided with the first air intake passage, and second
Cylinder 12 is provided with the second air intake passage, the ratio between delivery space V1 and delivery space V2 of the second cylinder 12 of the first cylinder 11
Value meets following relation: V2/V1≤0.3.Preferably, compressor 1 is gas refrigerant jet compressor.
First end of outdoor heat exchanger 2 is connected with exhaustor 14, the first end of indoor heat exchanger 3 and the first air intake passage phase
Even.Recuperative heat exchanger 4 includes the first heat exchanger channels and second heat exchanger channels of mutual heat exchange, the arrival end of the first heat exchanger channels with
First throttle element 5 it is in series with, the port of export of the first heat exchanger channels and the second air intake passage between second end of outdoor heat exchanger 2
Being connected, the arrival end of the second heat exchanger channels is connected with the second end of outdoor heat exchanger 2, and the port of export of the second heat exchanger channels is with indoor
It is in series with second section fluid element 6 between second end of heat exchanger 3.Wherein first throttle element 5 and second section fluid element 6 all play
The effect of reducing pressure by regulating flow.Alternatively.First throttle element 5 is capillary tube, choke valve, electric expansion valve or heating power expansion valve.Can
Selection of land, second section fluid element 6 is capillary tube, choke valve, electric expansion valve or heating power expansion valve.
Specifically, Recuperative heat exchanger 4 includes the first port a to the 4th port d, and the arrival end of the first heat exchanger channels is first
Port a, the port of export of the first heat exchanger channels is the second port b, and the arrival end of the second heat exchanger channels is the 3rd port c, and second changes
The port of export of the passage of heat is the 4th port d.First port a is connected with first throttle element 5, the second port b and the second cylinder 12
Being connected, the 3rd port c is connected with outdoor heat exchanger 2, and the 4th port d is connected with second section fluid element 6.
When refrigerating plant 100 works, the coolant discharged from the first cylinder 11 and the coolant discharged from the second cylinder 12 are at shell
Collecting in body 10, the coolant collected discharges and flows to carry out condensation heat radiation outdoor heat exchanger 2, from outdoor heat exchange from exhaustor 14
The coolant that device 2 is discharged is divided into two parts, and Part I coolant is by passing through the first port after the reducing pressure by regulating flow of first throttle element 5
A is flowed in the first heat exchanger channels, and the coolant in the first heat exchanger channels enters in flowing out from the second port b and flow to the second cylinder 12
Row compression.
Part II coolant is directly discharged into in the second heat exchanger channels by the 3rd port c, cold in the second heat exchanger channels
Matchmaker carries out reducing pressure by regulating flow from the 4th port d row to second section fluid element 6, and the coolant discharged from second section fluid element 6 is arranged to indoor
Heat exchanger 3 is evaporated heat absorption, is compressed in the coolant of indoor heat exchanger 3 discharge is drained into the first cylinder 11.Thus
Understand, enter into the coolant in the first heat exchanger channels and there is temperature difference between the coolant entered in the second heat exchanger channels, the
Coolant in one heat exchanger channels and the coolant in the second heat exchanger channels carry out heat exchange.
Owing to the ratio between delivery space V1 and delivery space V2 of the second cylinder 12 of the first cylinder 11 meets as follows
Relation: V2/V1≤0.3, is therefore drained in the second cylinder 12 quality of the coolant being compressed from the first heat exchanger channels and is less than
Be drained in the first cylinder 11 quality of the coolant being compressed from indoor heat exchanger 3, the coolant of the most whole refrigerating plant 100 is big
Part flows through indoor heat exchanger 3, to ensure the evaporation demand of indoor heat exchanger 3.
The change procedure of coolant is further described below with reference to the system pressure-enthalpy chart shown in Fig. 2.
From the beginning of compressor 1, the coolant 2 and 3 ' of the high pressure-temperature after compressor 1 compresses enters after discharging compressor 1
In outdoor heat exchanger 2, there is the temperature difference in outdoor heat exchanger 2 and outdoor environment temperature, heat is exchanged to outdoor by outdoor heat exchanger 2
Environment, thus the temperature of the coolant of high pressure-temperature can be reduced to and delivery chamber's external heat exchanger 2 at 5, if good effect of heat exchange coolant stream
Also have one section of supercool region then coolant can become 6 points after crossing outdoor heat exchanger 2.
The coolant of delivery chamber's external heat exchanger 2 is divided into secondary air road, after the first plume road is for first flowing through first throttle element 5
Throttling is reduced to 7 points, and the coolant state of 7 is gas-liquid mixture, this gas-liquid mixture toward compressor 1 the second cylinder 12 the
Two air intake passage flowings.Second plume road is the coolant towards indoor heat exchanger 3, before indoor heat exchanger 3, owing to being provided with
Recuperative heat exchanger 4, after this makes the first plume road coolant throttle, 7 and second strand of coolant do not throttle first 6 and carry out heat exchange.By
This second strand of coolant can be further cooled into 8 points, then enters back into second section fluid element 6, is throttled by second section fluid element 6
After become at 9 and enter into indoor heat exchanger 3；And progressively change into gaseous state 3 after the heat absorption of first strand of coolant and enter into the of compressor 1
It is compressed in two cylinders 12.
In above process, being cooled to 8 points owing to Recuperative heat exchanger 4 allows second strand of coolant again cross, this can improve refrigeration dress
Put the ability of 100, i.e. refrigerating capacity；And by being provided with compressor 1 according to embodiments of the present invention, allow after first burst of coolant heat exchange
3 dotted state enter the second cylinder 12 of compressor 1 and are compressed, then the compression process of 3 is represented by the 3-3 ' process of Fig. 2,
1-2 process relative to Fig. 2 clearly saves compression power consumption, and thus this compressor 1 and refrigerating plant 100 thereof can bring efficiency
Lifting.
Refrigerating plant 100 according to embodiments of the present invention, by arranging Recuperative heat exchanger 4 and making the row of the first cylinder 11
The ratio V2/V1 of the delivery space of air space and the second cylinder 12 is less than or equal to 0.3, can be effectively improved refrigerating plant 100
Performance, make refrigerating plant 100 easily reach optimal energy efficiency state.
In some embodiments of the invention, delivery space V1 of the first cylinder 11 and delivery space V2 of the second cylinder 12
Between ratio meet following relation: V2/V1≤0.15.Further, delivery space V1 of the first cylinder 11 and the second cylinder
Ratio between delivery space V2 of 12 also meets following relation: 0.05≤V2/V1≤0.12.Further, the first cylinder
Ratio between delivery space V1 and delivery space V2 of the second cylinder 12 of 11 also meet following relation: 0.07≤V2/V1≤
0.1。
As it is shown in figure 1, in some embodiments of the invention, compressor 1 also includes reservoir 13, the import of reservoir 13
Being connected with the first end of indoor heat exchanger 3, the gas outlet of reservoir 13 is connected with the first air intake passage.Specifically, from indoor
The coolant that heat exchanger 3 is discharged is drained in reservoir 13 and carries out gas-liquid separation, and the gaseous coolant separated is drained into the first gas
It is compressed in cylinder 11, thus by being provided with reservoir 13, can avoid the first cylinder 11 that liquid hit phenomenon occurs, improve compressor
The functional reliability of 1.
