Description
Technical field
The utility model relates to a kind of air-conditioner set gas-liquid separator, especially a kind of air conditioner with air-source heat pump group is used
Injection oil return gas-liquid separator.
Background technique
With the raising of people 's material life level, the requirement to living environment comfort is higher and higher, and air-conditioning becomes life
Essential living facilities in work.Meanwhile Status of Energy Sources unreasonable problem in China's is very prominent, a large amount of winter heating combustions
Coal is one of the main reason for causing winter air seriously to pollute." the northern area winter cleaning of national ten ministries and commissions joint publication
Heating planning (2017-2021 years) " policy instruction, northern various regions " coal changes clean energy resource " engineering will be all complete in the end of the year 2021
At.
Under the promotion that government policy requires, relevant policies are launched respectively in all parts of the country, widely popularize with air source heat pump
Air-conditioner set is that the coal of main alternative form changes electric project.However in the use process of air source heat pump because outdoor unit defrost with
And situations such as comfortable sexual experience of user declines caused by load variations, and compressor operating condition deteriorates, happens occasionally.It is defrosting
Or during load variations, since liquid refrigerant fails to entirely reach saturation or superheat state, part liquid in evaporator
If drop, which is directly entered compressor, can occur Wet Compression.So dividing in evaporator outlet to gas-liquid to be arranged between suction port of compressor
From device, it is ensured that into all gas of compressor, and lubricating oil is taken back compressor, to guarantee to compress eupraxic fortune
Turn.There are also defrostings to use electric expansion valve fully open, the mode of compressor high-speed cruising, still, due to gaseous refrigerant
The case where agent overheats, and compressor operating condition is caused to deteriorate happens occasionally.
Currently, gas-liquid separator used in air-conditioner set uses gravity and change in flow generally to carry out gas-liquid separation,
Such as Publication No.: the patent of CN206247719UD discloses a kind of gas-liquid separator and air conditioner, wherein the gas-liquid separator
It include: tank body;Escape pipe is inserted in tank body from the roof of tank body;Outlet tube is inserted in tank body from the side wall of tank body lower end;With
And air inlet liquid pipe, it is inserted in tank body from the roof of tank body, the lower end of air inlet liquid pipe is arranged to the sidewalls flex of tank body, and air inlet liquid
The lower end axis of plane and air inlet liquid pipe where the upper end axis and tank body axis of pipe is arranged in angle.The refrigerant of external mix state
When entering in tank body by air inlet liquid pipe, eddy flow can be formed along the wall flow of tank body, at this point, in the refrigerant of mixed state
Gaseous coolant is flowed to the top of tank body, and liquid refrigerants gathers under self gravitation effect to the bottom of tank body, so that into
Entering gaseous coolant and liquid refrigerants in tank body can be good at separating, but isolated effect is less desirable, especially in heat pump
It is also possible to there is a phenomenon where refrigerant drops to enter compressor when air-conditioner defrosting.Meanwhile the oil return hole of traditional gas-liquid separator
Positioned at gas-liquid separator bottom, it is also possible to exist since operating condition changes, a large amount of liquid refrigerants and lube oil retention are in gas-liquid
The case where separator causes oil-bearing layer liquid level to rise, and lubricating oil can not return to compressor, cause compressor oil starvation by oil return hole
Occur.

Capillary 7-1 sucks muffler 8, compressor is returned to together with gaseous refrigerant, thus with reaching the mesh of oil return.
Embodiment 2
When system defrosting or larger load variations, refrigerant gas in evaporator by gas-liquid separator air inlet pipe 2 into
Enter gas-liquid separator ontology 4, since 2 one end of gas-liquid separator air inlet pipe is divided into two branches, the refrigerant of one of branch
The drop of carrying is directly entered gas-liquid separation cylinder 5 under the action of inertia force, is trapped herein.Gaseous refrigerant is by air hole stream
Out, achieve the purpose that gas-liquid separation.Another branch gaseous refrigerant is passed directly into gas-liquid separator, due to refrigerant gas point
Stream, so that gas flow rate declines, some biggish drops are directly fallen, and achieve the purpose that gas-liquid separation.If gaseous state system simultaneously
Contain impurity in cryogen, also enters in gas-liquid separation cylinder 5 under the action of inertia force, and be deposited on 5 bottom of gas-liquid separation cylinder, make
Gas-liquid separation cylinder 5 has been also equipped with the function of thick effect filtering.The meeting of amount of liquid refrigerant increases significantly in gas-liquid separator at this time, liquid
The liquid level of state refrigerant can gradually rise, and can successively reach time low level according to the liquid level of the different liquid refrigerants of operating condition and return
Positions, the lube layer positions such as oil pocket partition 6-2, secondary high-order oil back chamber partition 6-3, high-order oil back chamber partition 6-4 also can
The positions such as low level oil back chamber partition 6-2, secondary high-order oil back chamber partition 6-3, high-order oil back chamber partition 6-4 are successively reached, no matter are moistened
Which position lubricating oil layer reaches, corresponding low level oil return float 3-2, secondary high position oil return float 3-3 and high-order oil return float 3-4
It will float vertically upward.Because 8 gaseous refrigerant of muffler is sucked with certain flow velocity by compressor, muffler 8 and corresponding time
Low level oil return capillary 7-2, secondary high position oil return capillary 7-3 and the high position junction oil return capillary 7-4 form local low pressure,
Then lubricating oil is inhaled by corresponding low level oil return capillary 7-2, secondary high position oil return capillary 7-3 and high position oil return capillary 7-4
Enter muffler 8, compressor is returned together with gaseous refrigerant, thus with reaching the mesh of oil return.
Embodiment 3
Under the operating condition of system defrosting, while oil back chamber oil return where refrigerant level, submerged by liquid refrigerant
Oil back chamber secondary low level oil return capillary 7-2, secondary high position oil return capillary 7-3 and high position oil return capillary 7-4 play throttling
Antihypertensive effect, so that returning liquid decompression gasification, the heat for absorbing overheat gaseous refrigerant, which reaches, reduces compressor air suction temperature, protection
The effect of compressor.
Present patent application has the following characteristics that 1. can adopt according to the variation of air conditioner load for different working conditions
With the different multiple oil return capillary oil returns of high and low position, solves existing gas-liquid separator because oil return hole site is fixed, in sky
The shortcomings that can not changing adjustment oil return when load variations according to oil level is adjusted, oil return effect is effectively guaranteed.2. the utility model
Two branches are set in gas-liquid separator entrance, deflecting all the way sets gas-liquid separation cylinder all the way, enhances the effect of gas-liquid separation
Fruit.3. this patent utilizes injection principle, oil return pipe has restriction effect, makes contained liquid refrigerant gasification in oil return, reduces
