Description
Technical field
The present invention relates to air conditioner technical fields, more particularly, to a kind of compressor and air-conditioning system.
Background technique
Existing heat pump air conditioner system includes end to end compressor, four-way valve, indoor heat exchanger, outdoor heat exchange
Device, throttling set composition, but for traditional air-conditioning system, pressure ratio must be controlled in a certain range, exceeding should
Range, the operation that system just can not be reliable and stable, especially under low-temperature heating operating condition, since outdoor environment temperature is low, pressure
The case where refrigeration dose of contracting machine sucking is few, and delivery temperature is high, and it is low that it is easy to appear heating efficiencies at this time, fluctuation of service；
The concept of Gas-supplying enthalpy-increasing is proposed for the phenomenon, currently with increasing a set of tonifying Qi auxiliary circulation in system one
The saturated vapor of shwoot after grade throttling is directly back in the compression chamber of compressor, is reduced delivery temperature and is improved system operation
Stability, but current tonifying Qi mode, i.e., in compression process, all there is suction and discharge loss in tonifying Qi and intermediate cavity tonifying Qi recompression
Greatly, clearance volume is big, and has stringent control range lower than intermediate pressure, limits the promotion of efficiency.
Summary of the invention
An object of the present invention is to provide a kind of compressor, must be tight to solve the pressure of air compensating system in the prior art
The problem of lattice control, and limit the promotion of efficiency.
In some illustrative embodiments, the compressor is arranged useful between the gas supplementing opening and compression chamber of the compressor
In the increasing enthalpy room of adjustment superfeed pressure
It is a further object to provide a kind of air-conditioning systems.
In some illustrative embodiments, the air-conditioning system, using above-mentioned compressor.
By above-mentioned compressor structure, the tonifying Qi into compressor compresses chamber is made to initially enter the increasing enthalpy room of compression chamber, it is real
Existing adjust automatically superfeed pressure, increasing enthalpy room distributes tonifying Qi according to the air pressure of compression chamber and flash vessel automatically, makes air-conditioning system without more
Remaining clearance volume, the intermediate pressure range allowed is wide, and adjustment space is improved, and facilitates the promotion of system effectiveness.
Detailed description of the invention
The drawings described herein are used to provide a further understanding of the present invention, constitutes part of this application, this hair
Bright illustrative embodiments and their description are used to explain the present invention, and are not constituted improper limitations of the present invention.In the accompanying drawings:
Fig. 1 is the structural schematic diagram of the air-conditioner system of illustrative embodiments according to the invention.
Specific embodiment
In the following detailed description, a large amount of specific details are proposed, in order to provide a thorough understanding of the present invention.But
It will be understood by those within the art that implementable present invention without these specific details.In other cases, without detailed
Well-known method, process, component and circuit are carefully described, in order to avoid influence the understanding of the present invention.
As shown in Figure 1, disclosing a kind of compressor, it is arranged between the gas supplementing opening 101 of the compressor 1 and 106 and compression chamber
There is the increasing enthalpy room for adjusting superfeed pressure.
By above-mentioned compressor structure, the tonifying Qi into compressor compresses chamber is made to initially enter the increasing enthalpy room of compression chamber, it is real
Existing adjust automatically superfeed pressure, increasing enthalpy room distributes tonifying Qi according to the air pressure of compression chamber and flash vessel automatically, makes air-conditioning system without more
Remaining clearance volume, the intermediate pressure range allowed is wide, and adjustment space is improved, and facilitates the promotion of system effectiveness.
In some illustrative embodiments, the first increasing enthalpy room is provided between the gas supplementing opening 101 and one stage of compression chamber 102
103；The second increasing enthalpy room 105 is provided between the gas supplementing opening 106 and two-stage compression chamber 104.
In some illustrative embodiments, a kind of air-conditioning system is disclosed, using above-mentioned compressor 1.
In some illustrative embodiments, air-conditioning system further include: the indoor heat exchange being sequentially communicated on refrigerant circulation path
Device 2, flash vessel 3, outdoor heat exchanger 4, four-way reversing valve 5, the compressor 1；The compressor 1 passes through the four-way reversing valve
5 are connected to the indoor heat exchanger 2 and outdoor heat exchanger 4 respectively；The tonifying Qi exhaust outlet of the flash vessel 3 and the compressor 1
Two gas supplementing openings 101 be connected to 106.
In some illustrative embodiments, it is arranged on the return-air duct between the four-way reversing valve 5 and the compressor 1
There is fluid reservoir 6, two exhaust outlets of the fluid reservoir 6 are connected to the gas returning port of two compression chambers of the compressor 1 respectively.
In some illustrative embodiments, air-conditioning system further include: setting is in the indoor heat exchanger 2 and the flash vessel
A nuclear one-stage throttling device 7 between 3.
In some illustrative embodiments, air-conditioning system further include: be arranged on the tonifying Qi exhaust outlet of the flash vessel 3
Two-step throttle device 8.
In some illustrative embodiments, a nuclear one-stage throttling device 7 and the two-step throttle device 8 are electric expansion valve
Or capillary.
Under heating circulation, the gas of the high temperature and pressure come out from compressor passes through indoor heat exchanger and a nuclear one-stage throttling device
Afterwards, become the liquid refrigerants of cryogenic high pressure, for refrigerant when entering flash vessel, having part refrigerant shwoot is gaseous state, the part gas
After state refrigerant is directly entered the increasing enthalpy room pressure regulation of two compression chambers of compressor after two-step throttle device, compressed into two
Chamber, enters exhaust cycle after compression, and another part refrigerant is discharged into outdoor heat exchanger from flash vessel, becomes later low
The gas returning port of the gaseous coolant of warm low pressure to two compression chambers enters compression chamber, becomes the gaseous coolant of high temperature and pressure after compression
It enters in exhaust cycle.
The circulatory system enters the tonifying Qi of compression chamber by the automatic adjustment of increasing enthalpy room, reduces the requirement to superfeed pressure, no
Adjustable extent by the pressure influence of system compresses chamber, superfeed pressure is more extensive；On the other hand by controlling throttle system,
The delivery temperature for reducing compressor improves the internal circulating load of refrigerant, improves ability and efficiency.
The above description of the embodiment is only used to help understand the method for the present invention and its core ideas；Meanwhile for this
The those skilled in the art in field, according to the thought of the present invention, there will be changes in the specific implementation manner and application range,
In conclusion the contents of this specification are not to be construed as limiting the invention.
