It is logical, so as to which first pressure refrigerant can be passed through into variable-volume storage chamber 141 (for example, to be compressed is low by transfiguration air entry 142
Press refrigerant), transfiguration cylinder 14 carries out normal compression work, and first pressure refrigerant is compressed to obtain HTHP refrigerant,
Now the twin-tub of transfiguration jet compressor 100 operates.When transfiguration valve 2 is located at blocking position, can lead into variable-volume storage chamber 141
Enter second pressure refrigerant (for example, high pressure refrigerant), now the pressure of second pressure refrigerant through transfiguration jet compressor 100 with compressing
The pressure of the refrigerant (namely refrigerant after the compression of transfiguration cylinder 14) obtained afterwards is substantially the same, and now transfiguration cylinder 14 is without pressure
Contracting work, the operating of the single cylinder of transfiguration jet compressor 100；And because transfiguration air entry 142 and variable-volume storage chamber 141 are cut-offs,
Therefore first pressure refrigerant can not enter variable-volume storage chamber 141 by transfiguration air entry 142.Wherein, second pressure refrigerant is preferred
The refrigerant discharged after being compressed for transfiguration jet compressor 100.
Air jet system 3 is located on compressor body 1, and as shown in Figure 1-Figure 3, air jet system 3 is located at outside compressor body 1,

Matchmaker).Thus, by setting air jet system 3, the 3rd pressure refrigerant that is sprayed into by air jet system 3 can with often fortune compression chamber 131 and
It is compressed after first pressure refrigerant mixing in variable-volume storage chamber 141, delivery temperature can reduce, and this just compresses transfiguration jet
The Low-Temperature Reliability of machine 100 improves, and refrigerant system capacity (such as heating capacity) increase, and cold medium flux increase, this is in low temperature bar
Under part, the reliability of transfiguration jet compressor 100 can be equally improved, moreover, it is achieved that quasi- two-stage compression circulates, optimizes circulation
Efficiency, Partial shrinkage work(is saved, improve the heat exchange efficiency of evaporator, can be with improving energy efficiency.
Wherein, the pressure of first pressure refrigerant is less than the pressure of the 3rd pressure refrigerant, and the pressure of the 3rd pressure refrigerant is less than
The pressure of second pressure refrigerant.Here, the 3rd pressure refrigerant can be connected to condenser and evaporator from air-conditioning system
Between flash vessel middle pressure refrigerant, it is of course also possible to which directly external pipeline is to normal fortune compression chamber 131 and variable-volume storage chamber 141
Inside it is passed through middle pressure refrigerant.It is understood that the specific pressure of first pressure refrigerant, second pressure refrigerant and the 3rd pressure refrigerant
Force value can specifically be set according to the transfiguration jet compressor 100 of reality.
Transfiguration jet compressor 100 according to embodiments of the present invention, can be with by the way that transfiguration valve 2 is located in compression mechanism
The volume of compressor body 1 is effectively reduced, reduces the space-consuming of compressor body 1, by setting air jet system 3, realizes spray
Airway dysfunction, so as to realize quasi- two-stage compression kind of refrigeration cycle.
According to some embodiments of the present invention, as shown in Figure 3 and Figure 4, air jet system 3 includes jet channel 151, and jet is led to
Formed with suitable for the normal fortune puff prot 152 connected with normal fortune compression chamber 131 and suitable for being connected with variable-volume storage chamber 141 on road 151
Transfiguration puff prot 153.Now the 3rd pressure refrigerant can be entered often in fortune compression chamber 131 by often transporting puff prot 152, and be led to
Transfiguration puff prot 153 is crossed to enter in variable-volume storage chamber 141.Often fortune air injection control device is often provided with fortune puff prot 152, often fortune spray
Gas control device is used to control whether to be passed through the 3rd pressure refrigerant into normal fortune compression chamber 131.It is provided with and becomes at transfiguration puff prot 153

During being rotated in chamber 131, at some moment, normal pumping piston 132 can block often fortune puff prot 152, and now the 3rd pressure is cold
Matchmaker can not be entered often in fortune compression chamber 131 by often transporting puff prot 152, and can be avoided in other moment, normal pumping piston 132
Often fortune puff prot 152 is opened, so as to which the 3rd pressure refrigerant can be entered often in fortune compression chamber 131 by often transporting puff prot 152.
First check-valve is configured to irreversibly deliver the 3rd pressure refrigerant to normal fortune compression chamber 131, and often transports compression chamber 131
Interior refrigerant can not enter jet channel 151 by often transporting puff prot 152.First check-valve is normal in closure under normal conditions
The state of puff prot 152 is transported, now the 3rd pressure refrigerant can not enter often fortune compression chamber 131 by often transporting puff prot 152, and
When the pressure of the 3rd pressure refrigerant in jet channel 151 is more than the opposite side of first check-valve (i.e. often in fortune compression chamber 131
Refrigerant pressure) when, first check-valve is opened, and the 3rd pressure refrigerant can enter often fortune compression chamber by often transporting puff prot 152
In 131.
Alternatively, first check-valve can be adjacent to exhaust side (the i.e. exhaust outlet place of Chang Yunqi cylinders 13 of Chang Yunqi cylinders 13
Side) set.Thus, because the pressure of the 3rd pressure refrigerant sprayed into by air jet system 3 is more than first pressure refrigerant

More than second check-valve opposite side (i.e. often fortune compression chamber 131 in refrigerant pressure) when, second check-valve open, the 3rd pressure
Refrigerant can be entered in variable-volume storage chamber 141 by transfiguration puff prot 153.
Alternatively, second check-valve can be adjacent to exhaust side (the i.e. exhaust outlet place of transfiguration cylinder 14 of transfiguration cylinder 14
Side) set.Thus, because the pressure of the 3rd pressure refrigerant sprayed into by air jet system 3 is more than first pressure refrigerant
Pressure, therefore second check-valve is arranged on to the side of the close exhaust outlet of transfiguration cylinder 14, work done during compression can be saved, reduces and becomes
Hold the energy consumption of jet compressor 100.
In some embodiments of the invention, as shown in figures 3 to 6, often fortune air injection control device is piston valve, and transfiguration is sprayed
