Summary of the invention the object of the present invention is to provide a kind of scroll compressor with gas compensation function, thereby realizes that compressor is being lower than proper functioning under normal design use evaporating pressure, the high pressure ratio operating mode, and improves the ability and the efficient of compressor.
The object of the present invention is achieved like this: the scroll compressor with gas compensation function, comprise and decide scroll element and moving scroll element, it is characterized in that on scroll element, having the tonifying Qi hole, this tonifying Qi hole with by moving, decide the sealed volume that scroll element forms be connected in the pressurized gas process, and be connected with the system air supply source by blowdown pipe, make system's air supply source in sealed volume, charge into gas, increase the air displacement of compressor.
And have a tonifying Qi hole on the corresponding scroll element of sealed volume at least, the suction pressure in a plurality of tonifying Qi hole that is connected simultaneously with same sealed volume is identical.
Each sealed volume can be successively in the continuous operation process of compressor be in diverse location on the tonifying Qi hole be connected.
Scroll compressor provided by the invention, in air-breathing, compression normally, exhaust process, can also be as required, by being arranged on the tonifying Qi hole on the scroll element, for each sealed volume that is formed by fixed, moving scroll element before air-breathing end back, exhaust begin provides extra gas, this not only can increase air displacement under the situation that does not influence the compressor air suction amount, can also cool off the gas that is compressed intensification in the former sealed volume simultaneously.The tonifying Qi hole can be opened and decided on the scroll element, also can open on moving scroll element, preferably in the end of deciding scroll element.Each sealed volume can be successively in the continuous operation process of compressor be in diverse location on the tonifying Qi hole be connected, in whole compression process, implement multistage tonifying Qi like this.Each sealed volume can corresponding be provided with one or more and its tonifying Qi hole that is communicated with simultaneously, and best correspondence is provided with a tonifying Qi hole.If correspondence is provided with two above tonifying Qi holes, the suction pressure in each hole should be identical.Two relatively independent sealed volume can be mended the gas into different pressures.
Characteristics of the present invention are: except that the performance with existing scroll compressor, also have the function of the sealed volume make-up gas after sealing.The gas that benefit is gone into has improved the air displacement of compressor, and cold, heat that system is obtained increase, and the compressor work done increases.Mend the gas of going into and to reduce original gas that is compressed intensification in the sealed volume, delivery temperature is descended, realize the proper functioning of compressor under low evaporating pressure, high pressure ratio.In the increase of compressor horsepower and the system of living in the increase of cold, heat compare very little, so the low temperature efficient of system and energy indexes obtain bigger raising.

Fig. 3 is used in the schematic diagram of air-conditioning system for common scroll compressor.
Fig. 4 is used in the schematic diagram of air-conditioning system for the present invention.
The invention will be further described below in conjunction with accompanying drawing for embodiment:
As shown in Figure 1, scroll compressor housing 8 is provided with outlet pipe 1 and sucking pipe 2, be provided with the last lower support 5,10 that is used for fixing support scroll component 3,4 and electric machine main shaft 6 in the housing, and motor stator 7 and rotor 9, main shaft top eccentric shaft is connected with moving scroll element 4.Therefore the prior art that is configured to owing to above-mentioned scroll compressor no longer describes in detail.The present invention is deciding to have opened 3 tonifying Qi holes 13,14,15 on the scroll element, communicates with the system air supply source through blowdown pipe 12 respectively.3 tonifying Qi holes are and 11, the 16 corresponding settings of 2 sealed volume, see Fig. 2, and wherein tonifying Qi hole 13,14 communicates with sealed volume 11, and tonifying Qi hole 15 is connected with sealed volume 16.The suction pressure in tonifying Qi hole 13,14 is identical, and is different with the suction pressure in tonifying Qi hole 15.Each sealed volume can have the tonifying Qi hole, also can be to offer at interval.Among Fig. 2, compress when mobile to the center when sealed volume 11,16, sealed volume 11,16 is withdrawed from tonifying Qi hole 13,14,15 gradually, before tonifying Qi hole 15 enters sealed volume 11, oneself withdraws from sealed volume 11 tonifying Qi hole 13,14, remains in operation, and tonifying Qi hole 15 enters sealed volume 11.Like this, sealed volume 11 has been carried out a tonifying Qi by tonifying Qi hole 13,14, has carried out a tonifying Qi again by tonifying Qi hole 15, has promptly carried out the two-stage tonifying Qi in compression process.
Fig. 4 is applied to fundamental diagram on the air-conditioning system for the present invention, and during proper functioning, solenoid valve 17 cuts out, and the tonifying Qi loop is blocked, and is consistent with common air-conditioning work shown in Figure 3; When outdoor temperature was very low, evaporating pressure was very low, and compressor 20 abilities are also fallen very lowly, this moment, solenoid valve 17 was opened, the liquid refrigerant that comes out from condenser 18 is distributed one the tunnel, after throttling, enters heat exchanger 19 evaporations, further cool off the liquid refrigerant of major loop, gas refrigerant after the evaporation enters the sealed volume that scroll component forms through air supply passage (12), tonifying Qi hole, together with original gas in the sealed volume, further compressed, discharge condensation.Because it is low to cover the refrigerant temperature of sealed volume,, delivery temperature is descended with original refrigerant cools that is compressed intensification; Because tonifying Qi is carried out after air aspiration cavity sealing, does not influence gettering quantity, but air displacement increased, so compressor work increases, and the load of condenser increases, and heating capacity increases; Because main circuit refrigerant is by cold excessively, so refrigerating capacity increases, the ability of compressor gets a promotion.The increase of compressor horsepower is compared very little with the increase of cold, heat, efficient obtains bigger raising, has promptly realized the proper functioning of compressor under low evaporating temperature high pressure ratio, has enlarged the operating range of air-conditioning.21 is outdoor heat exchanger among Fig. 3,4,22 throttle valve, and 23 is the branch road throttle valve among Fig. 4.
