Technical field
The utility model is related to a kind of preparation of air-conditioning, especially a kind of multi-online air-conditioning system is specifically a kind of fast
The multi-online air-conditioning system of speed defrosting.
Background technology
Air conditioner in winter heating operation when, the easy frosting of outdoor unit heat exchanger, common method is by by air conditioner
The method of refrigeration operation is switched to remove the frost on heat exchanger.But when the heat exchanger of air conditioner is made of more circuit
When, refrigerant will enter different circuits by distributor.Since the air quantity of exchanger base position is usually all smaller, thus
Circuit at this other circuits that compare are more easy to frosting.Meanwhile the order of heat exchanger defrosting is typically gradually to eliminate from top to bottom
, therefore the whole defrosting time of air conditioner is by the defrosting speed depending on heat exchanger lowest position.And the defrosting of air conditioner
Time directly influence it heating performance and user Experience Degree, therefore, design a kind of air conditioner system for being capable of quickly defrosting
System, is necessary.
Utility model content
The purpose of this utility model is to provide a kind of multi-gang air-conditioner system of quickly defrosting in view of the deficiencies of the prior art
System, can greatly shorten defrosting time, improve the heating performance and user experience of air conditioner.
The technical solution of the utility model is：
A kind of multi-online air-conditioning system of quickly defrosting, compressor, oil separation including being sequentially connected and forming circuit
Device, four-way valve, outdoor unit heat exchanger, heating electronic expansion valve module, electronic expansion valve of indoor unit, indoor set heat exchanger and gas-liquid
Separator, the heat that the outdoor unit heat exchanger includes multiple parallel connections return road；Each heat returns road transverse direction arranged in parallel in one
In a vertical plane, left end is interconnected, and right end connects distributor respectively；One heat of the lowermost returns road and the distribution
Check valve is equipped between device.
Further, the left end that each heat returns road is connected respectively to a gas collecting tube and is interconnected.
Further, the outdoor unit heat exchanger is finned heat exchanger, flows surrounding air by wind turbine, forced convertion
Heat exchange.
The beneficial effects of the utility model：
The utility model is designed reasonably, it is simple in structure, it is easy to produce, the defrosting time of air conditioner can greatly be shortened,
The heating performance of air conditioner is improved, the Experience Degree of user is effectively improved, is worthy to be popularized.

Fig. 2 is the heat exchanger structure schematic diagram of the utility model.
Wherein：1 compressor, 2 oil eliminators, 3 four-way valves, 4 outdoor unit heat exchangers, 5 heating electronic expansion valve modules, Room 6
Interior machine electric expansion valve, 7 indoor set heat exchangers, 8 gas-liquid separators, 9 gas collecting tubes, 10 heat return road, 11 check valves, 12 distribution
Device.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
" on " " under " involved in text " left side " " right side " is not the restriction to technical solution for sake of convenience.
As shown in Figure 1, a kind of multi-online air-conditioning system of quickly defrosting, compressor 1, oil including forming circuit successively
From device 2, four-way valve 3, outdoor unit heat exchanger 4, heating electronic expansion valve module 5, electronic expansion valve of indoor unit 6, indoor heat exchanger
7th, gas-liquid separator 8.Specifically it is connected as：Compressor is connected by oil eliminator with four-way valve, and C-terminal and the outdoor unit of four-way valve change
Hot device is connected, and outdoor unit heat exchanger by passing through electronic expansion valve of indoor unit and indoor unit according to this after heating electronic expansion valve module
Heat exchanger, indoor set heat exchanger outlet connection four-way valve E ends, by entering gas-liquid separator, gas-liquid separator behind four-way valve S ends
Outlet be connected with the import of compressor.
Cyclic process of the refrigerant in above-mentioned refrigeration system be：The gaseous state of high temperature and pressure by the compression of compressor 1 is cold
Matchmaker is by oil eliminator 2, by refrigerant and lubricating oil separation.Wherein, refrigerant enters outdoor unit heat exchanger by the C-terminal of four-way valve 3
4, lubricating oil enters gas-liquid separator 8.The gaseous coolant of high temperature and pressure exchanges heat in outdoor unit heat exchanger 4 and is condensed into medium temperature and medium pressure
Liquid refrigerants, using heating electronic expansion valve module 5 after enter indoor.Side indoors, the liquid of the medium temperature and medium pressure are cold
Matchmaker first passes through indoor electronic expansion valve 6 and carries out throttling decrease temperature and pressure, is exchanged heat subsequently into indoor set heat exchanger 7 and evaporated.
Low-temp low-pressure gaseous coolant after evaporation successively enters gas-liquid separator 8 behind the E ends of four-way valve 3 and S ends.By gas-liquid point
From rear, pure gaseous coolant enters compressor 1 and is compressed machine.
As shown in Fig. 2, the heat that the outdoor unit heat exchanger includes multiple parallel connections returns road 10；It is horizontal that each heat returns road 10
To arranged in parallel in a vertical plane, and, the left end that each heat returns road 10 is connected respectively to a gas collecting tube 9 and phase
Intercommunicated, right end connects distributor 12 respectively.Wherein, one heat of the lowermost, which is returned, is equipped with list between road and the distributor 12
To valve 11.
When air conditioner is in heating operation, refrigerant returns road 10 from distributor 12 into heat.Due to check valve 11
Effect, the lowermost heat return in road do not have refrigerant by, the circuit is made not have heat exchange, also would not frosting.
When air conditioner refrigeration or defrosting operating, refrigerant is from gas collecting tube 9 into including bottom heat returns road
Each heat returns road 10.There is no frosting since the lowermost heat returns road in heating operation, in defrosting operating, pass through
The heat of the refrigerant in bottom circuit can be used for that its adjacent loop is helped to defrost, so as to greatly accelerate defrosting speed
Degree.
The outdoor unit heat exchanger is finned heat exchanger, flows surrounding air by wind turbine, forced-convection heat transfer, is improved
Heat exchange efficiency.
It is same as the prior art or the prior art can be used realized that the utility model is not directed to part.
