Specific embodiment
In order to make those skilled in the art more fully understand application scheme, below in conjunction in the embodiment of the present application
Attached drawing, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described embodiment is only
The embodiment of the application a part, instead of all the embodiments.Based on the embodiment in the application, ordinary skill people
Member's every other embodiment obtained without making creative work, all should belong to the model of the application protection
It encloses.
It should be noted that the description and claims of this application and term " first " in above-mentioned attached drawing, "
Two " etc. be to be used to distinguish similar objects, without being used to describe a particular order or precedence order.It should be understood that using in this way
Data be interchangeable under appropriate circumstances, so as to embodiments herein described herein.In addition, term " includes " and " tool

Process, method, system, product or equipment those of are not necessarily limited to be clearly listed step or unit, but may include without clear
Other step or units listing to Chu or intrinsic for these process, methods, product or equipment.
The mechanism that slide plate and roller are detached from when the course of work and absorbing gas belt liquid of compressor pump: see that Fig. 1 and 2, crankshaft 1 exist
Under the rotation linkage of motor, roller 2 is driven to rotate in cylinder 3, slide plate 4 follows movement with roller 2 under back pressure effect, and
Compression chamber in cylinder 3 is divided into suction chamber and discharge chamber；Suction air cavity constantly occurs in the rotary motion lower volume of roller 2
Change and then complete the air-breathing and exhaust process of compression.
When the refrigerant that dispenser air intake duct 5 sucks is gas-liquid binary states, cylinder 3 is flowed by cylinder air entry 6 and is worked
Intracavitary liquid refrigerant absorbs heat evaporation under working chamber hot environment, and flash evapn causes the pressure in working chamber to increase, sliding
Piece 4 is bonded under the action of back pressure with roller 2, but cylinder 3 works cavity pressure when instantaneously increasing, and slide plate is mutated in head pressure
In the case where be bonded with roller, slide plate generates shock with roller under back pressure effect again after air-breathing, and generates and " rattles away
Sound ", the phenomenon often occur in underload low-frequency operation, keep the experience of air conditioner user sense of hearing poor, cause discomfort.
Embodiment 1
On the basis of existing compressor, in order to solve underload low-frequency operation absorbing gas belt liquid and the slide plate because generating with liquid
Roller problem is hit, dispenser air intake duct 1 and exhaust pipe 7 are connected to by bypass line 8, the high-temperature gas that exhaust pipe is discharged
Dispenser 9 can be introduced by bypass line；The heat of high-temperature gas can evaporating getter sucking liquid refrigerant, alleviate air-breathing
Abnormal sound problem caused by band liquid, is shown in Fig. 1.
Control valve 10 is provided on bypass line, for controlling the bypass amount of high-temperature exhaust air, appropriate bypass amount can be solved
Air-breathing solution dehumidification while migration, but excessive bypass will lead to pump housing leakage loss and suction superheat.Appended drawing reference 11 is lower flange, and 12 are
Upper flange.
Compressor is easy to happen absorbing gas belt liquid in light load low-frequency operation and with compressor abnormal sound, usually in suction and discharge
When pressure difference is less than 1MPa, running frequency is less than 30Hz, the risk that compressor generates abnormal sound is larger.
When compressor generates " sound of rattling away " abnormal sound, due to hitting again after slide plate and roller disengaging, shock when, is radially generated
Biggish vibrational energy can judge and then with the vibration acceleration at slide plate back to judge the stroke speed of slide plate and roller
Absorbing gas belt liquid measure under this operating status.Vibration acceleration is detected using vibrating sensor, and vibrating sensor setting is carried on the back in slide plate
On the corresponding compressor main part shell in portion.
When the slide plate back vibration acceleration measured is greater than 30m/s2When show at this time air-breathing have band liquid phenomenon, but hit produce
Raw abnormal sound is not noticeable, and user experience is unobvious；When vibration acceleration is greater than 100m/s2When show that air-breathing has serious band at this time
Liquid phenomenon, the abnormal sound for hitting generation are easy to discover and generate sense of discomfort.
The bypass amount of high-temperature exhaust air, vibrating sensor connection control are adjustably controlled by the control valve being arranged on bypass line
Valve processed.To avoid compressor operating caused by excessively bypassing abnormal, can using the vibration acceleration at slide plate back as judgment basis,
The vibration acceleration at slide plate back is in 30m/s under normal circumstances2Show in ± 30% range air-breathing have slightly with liquid and generate
Abnormal sound is not noticeable, and exhaust bypass amount on this basis controls slide plate back vibration acceleration best in this range.Slide plate back
The vibration acceleration in portion is in 20m/s2Show air-breathing when following without liquid, if the vibration acceleration at exhaust bypass excess slide plate back
Within this range, the adverse effects such as compressor performance decline, suction and discharge overheat be may cause.The vibration acceleration at slide plate back exists
40m/s2Show existing certain band liquid measure when above, can obviously discover abnormal sound at this time and the higher abnormal sound of vibration acceleration is tighter
Weight, shock abnormal sound easily cause user experience uncomfortable when larger.
Therefore, it is greater than 40m/s in vibrating sensor detection vibration acceleration2When air intake duct and exhaust pipe pressure difference value
Running frequency value with compressor is as the threshold value for controlling valve opening.
Exhaust is passed directly to suction side, main purpose is to solve to have when the operation of single-rotor compressor underload low-frequency band liquid
It rattles away this particular problem of sound；Air-breathing is led in exhaust to need to control ventilatory capacity, to prevent the production in other accidental conditions
Raw adverse effect.
The bypass high pressure overheated gas that this method provides reduces the design scheme and high pressure gas of absorbing gas belt liquid to dispenser
The scaling method and system control strategy of body bypass amount, under the premise of guaranteeing that rationally bypass reduces absorbing gas belt liquid, not to compression
The performance of machine, reliability, noise have a negative impact.
