Specifically, when the cold medium shortage in compression chamber 1a, the tonifying Qi pipeline 42 and first of pressure release tonifying Qi sharing unit 40
Passage 313 is connected, and now outside refrigerant is supplemented in compression chamber 1a by tonifying Qi pipeline 42 and first passage 313, and then is avoided
Cold medium shortage in compression chamber 1a, and cause the too low problem of the compression efficiency of screw compressor 100 to occur.
When the refrigerant in compression chamber 1a be in overcompression when, now, the pressure relief pipe 43 of pressure release tonifying Qi sharing unit 40 with
First passage 313 is connected, and compression chamber is discharged in the high pressure refrigerant part in compression chamber 1a by first passage 313 and pressure relief pipe 43
1a, in this way, avoiding high pressure refrigerant in compression chamber 1a by overcompression, and then reduces the compression power consumption of screw compressor 100.
The utility model shares single by setting first passage 313, pressure release tonifying Qi on the quiet disk body 31 of fixed scroll 30
The connecting line 41 of first 40 one end is connected with first passage 313, and the other end of pressure release tonifying Qi sharing unit 40 blowdown pipe
Road 42 and pressure relief pipe 43 are switchably connected with first passage 313, so so that screw compressor 100 is in tonifying Qi or pressure release
When, first passage 313 is in running order all the time, so as to advantageously reduce the clearance volume of screw compressor 100, and then reduces
The power consumption of screw compressor 100.
Refer to Fig. 2, above-mentioned first passage 313 has and connected with compression chamber 1a and along axially extending the of quiet disk body 31
One section of 313a and connected with first paragraph 313a and along the second segment for axially penetrating through the periphery wall of quiet disk body 31 of quiet disk body 31
313b, and second segment 313b connects with the connecting line 41 of pressure release tonifying Qi sharing unit 40.It is understood that quiet disk body 31
It is radial and axial be it is orthogonal, i.e., the first paragraph 313a of first passage 313 is connected with second segment 313b and is mutually perpendicular to set
Put.Because first passage 313 is to be drilled to be formed by drilling machine, by the first paragraph 313a of first passage 313 along quiet disk body 31 axle
To extension, second segment 313b the radially extending along quiet disk body 31 of first passage 313 is arranged such, is easy to drilling machine to drill,
And then be conducive to improving the processing efficiency of fixed scroll 30.
Obviously, first passage 313 can also be set along the quiet disk body 31 that axially penetrates through of quiet disk body 31.It is arranged such, more just
In drilling machine drilling, and then be conducive to improving the processing efficiency of fixed scroll 30.
In order to improve the tonifying Qi speed and pressure release speed of screw compressor 100, the quiet disk body 31 is provided with and compression chamber 1a
Multiple first passages 313 of connection, and each first passage 313 connects setting with adapter.
When the cold medium shortage in compression chamber 1a, outside refrigerant can enter compression chamber 1a by multiple first passages 313
It is interior, compared to by a first passage 313, to coolant adding in compression chamber 1a, multiple first passages 313 can be in the same time
It is interior to supplementing more refrigerants in compression chamber 1a, and then improve the coolant adding speed of the screw compressor 100.Work as compression chamber
When refrigerant in 1a is in overcompression state, the part overvoltage refrigerant in compression chamber 1a can be by the row of multiple first passages 313
Go out compression chamber 1a.Refrigerant is outwards discharged compared to by a first passage 313, multiple first passages 313 can be in the same time
It is interior to giving off more refrigerants in discharge chamber 1b, and then improve the pressure release speed of the screw compressor 100.
It should be noted that the quantity of first passage 313 and position can be set according to actual conditions, here, not
Do specific restriction.
The compression chamber 1a of above-mentioned screw compressor 100 is outwards followed successively by higher-pressure region, middle nip, low from the center of quiet disk body 31
Nip.First passage 313 connects setting with the middle nip of compression chamber 1a.It should be noted that the low-pressure area of compression chamber 1a is cold
Gas pressure is relatively low, if first passage 313 is connected with low-pressure area, cannot accurately to coolant adding amount in compression chamber 1a, i.e.,
Occur that the excessive or very few problem of coolant adding amount occurs, supplemented the compression performance that can reduce screw compressor 100 at least,
Supplemented the power consumption that can at most increase screw compressor 100.The higher-pressure region refrigerant air pressure of compression chamber 1a is higher, if by first passage
313 connect with higher-pressure region, due to refrigerant air pressure of the refrigerant air pressure less than higher-pressure region for supplementing, so can then cause from compression chamber 1a
The refrigerant air pressure of discharge does not reach requirement.Therefore, first passage 313 is connected relatively good with the middle nip of compression chamber 1a, specifically
, in the cold medium shortage of middle nip, the tonifying Qi pipeline 42 of pressure release tonifying Qi sharing unit 40 is connected with first passage 313, to cause
Outside refrigerant can enter to the middle nip of compression chamber 1a by tonifying Qi pipeline 42 and first passage 313.In the refrigerant of middle nip
Gas is in overcompression, and the pressure relief pipe 43 of pressure release tonifying Qi sharing unit 40 is connected with first passage 313, with the portion of nip in causing
Point refrigerant is discharged by first passage 313 and pressure relief pipe 43, so avoid compression chamber 1a middle nip and higher-pressure region it is cold
Gas presses through height, advantageously reduces the power consumption of screw compressor 100.

Electric machine assembly 60 is exchanged heat, and then is conducive to improving the refrigeration of screw compressor 100.
Further, controller 250 is additionally operable to the ratio of the pressure of inspiration(Pi) and pressure at expulsion according to screw compressor 100,
The switch valve 95 on the second channel 314 of screw compressor 100 is controlled to open or close.
Specifically, air-conditioner 200 also has the third working condition under control of the controller 250：First flash vessel 230
Connected with first passage 313 by the tonifying Qi pipeline 42 of pressure release tonifying Qi sharing unit 40, at the switch valve 95 on tonifying Qi pipeline 90
In open mode, to cause that the second flash vessel 260 is connected with second channel 314.Now, the first control valve 240 and second is controlled
Valve 270 is in opening, and the first flash vessel 230 and the second flash vessel 260 simultaneously participate in circulation, and middle pressure refrigerant is distinguished
It is passed through in compression chamber 1a, realizes first passage 313 and second channel 314 simultaneously to the operation of coolant adding in compression chamber 1a, it is real
Existing quasi- three stage compression.
Preferred embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited,
It is every under inventive concept of the present utility model, the equivalent structure made using the utility model specification and accompanying drawing content is become
Change, or directly/be used in other related technical fields indirectly and be included in scope of patent protection of the present utility model.
