Description
Technical field
The present invention relates to the vehicle-mounted refrigeration control technical field of air conditioning for automobiles, in particular it relates to a kind of oil electricity mixing caravan
Air-conditioning system.
Background technology
One of the core system of caravan air-conditioning system as motor homes system, it is one of important indicator of caravan quality.With
Expanding economy and the continuous improvement of living standard, requirement more and more higher of the user to caravan air-conditioning.Traditional caravan air-conditioning system
The single fuel oil by consumption automobile of uniting to provide electric power and power for system, and its general principle is as shown in figure 1 above：
When automobile engine is run, generator operation is driven by power transmission (belt), will after generator operation
Caused electric energy part deposit battery, a part are supplied to automobile electrical equipment；When refrigeration system needs to start, compression
The sucker of machine rotates together with the belt pulley that engine connects, so as to provide energy for refrigeration system.
The specific functionality of caravan so that the application of caravan air-conditioning and common in-vehicle are also different.Common in-vehicle is as traffic work
Tool, move during most of the time automobile, and the time of caravan motion and parking is essentially the same, or even the time of parking is far above
Run time.Traditional approach provides power by fuel consumption for vehicle-mounted refrigerating system completely, (ratio after engine stop operates
Such as temporary parking), compressor can also stop, and such refrigeration system cannot work again.If it is intended to ensure that refrigeration system is normal
Operation, also it is essential to ensure that engine does not stop working under dead ship condition.This can bring many consistency in actual applications, together
When can also increase many extra costs.

Embodiment
With reference to specific embodiment, the present invention is described in detail.Following examples will be helpful to the technology of this area
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill to this area
For personnel, without departing from the inventive concept of the premise, some changes and improvements can also be made.These belong to the present invention
Protection domain.
The present invention provides a kind of oil electricity mixing caravan air-conditioning system, as shown in Figure 2 to Figure 3, including first be connected in parallel
The compressor circuit 2 of compressor circuit 1 and second, first compressor circuit 1 and second compressor circuit 2 are one end
Connected with total air-breathing end 10, the other end connects with total outlet side 11；
First compressor circuit 1 includes gas separation unit 6, the first compressor 3 and the first oil 8 being sequentially connected, its
In, the gas separation unit 6 connects with total air-breathing end 10, and first oil 8 connects with total outlet side 11；
Second compressor circuit 2 include connection the second compressor 4 and the second oil 9, second compressor 4 with
Total air-breathing end 10 connects, and second oil 9 connects with total outlet side 11；
Unidirectional stop valve 5 is provided with first compressor circuit 1, the second compressor circuit 2.
Wherein, the total air-breathing end 10 connects automobile air-conditioning evaporator gas outlet, and it is empty that total outlet side 11 connects automobile
Adjust condenser air inlet.During to avoid the first compressor circuit 1 or the second both patterns autonomous working of compressor circuit 2, system
Cryogen will not be lost in and go to the wrong way loop, increase multiple unidirectional cutoff valve controls fluid trends in system.
As shown in figure 3, the shunting of total air-breathing end 10 forms the first suction end 12 and the second suction end 13；Wherein, it is described
First suction end 12 is connected with gas separation unit 6, and unidirectional stop valve is provided with the pipeline by the first suction end 12 to gas separation unit 6
5；Second suction end 13 connects with the second compressor 4, is provided with the pipeline by the compressor 4 of the second suction end 13 to the second
Unidirectional stop valve 5.
Total outlet side 11 is converged by the first outlet side 14 and the second outlet side 15 to be formed；Wherein, first outlet
End 14 is connected with the first oil 8, and unidirectional stop valve 5 is provided with the pipeline by the outlet side 14 of the first oil 8 to the first；Described
Two outlet sides 15 are connected with the second oil 9, and unidirectional stop valve 5 is provided with the pipeline by the outlet side 15 of the second oil 9 to the second.
In first compressor circuit 1, the liquid outlet of first oil 8 and the first compressor 3 connect and compose loop,
Meanwhile the gas outlet of first oil 8 connects with total outlet side 11；In second compressor circuit 2, second oil
9 liquid outlet and the second compressor 4 connect and compose loop, meanwhile, the gas outlet of second oil 9 connects with total outlet side 11
It is logical.To ensure to appoint when the first compressor circuit or the second compressor circuit work, refrigeration oil can be returned normally under each mode of operation
Return to associated compressors, individually match somebody with somebody an oil for each compressor.
The gas separation unit 6 is arranged on the loop that the liquid outlet of first oil 8 and the first compressor 3 connect and compose
Outside.
Unidirectional stop valve 5, the unidirectional cutoff are provided with the pipeline that second compressor 4 connects with total air-breathing end 10
Valve 5 is arranged on outside the loop that the liquid outlet of second oil 9 and the second compressor 4 connect and compose.
First compressor 3 is electrically-driven compressors, and second compressor 4 is caravan compressor of air conditioner.Second
Do not include gas separation unit in compressor circuit 2, this determines that caravan carries compression mainly due to different type compressor arrangement
Machine (i.e. the second compressor) is oblique tray type compressor, therefore all without with qi leel in practical application, and the first compressor is totally-enclosed
Rotor compressor, so must have gas separation unit.
In the caravan air-conditioning system, the first compressor 3 works when different from the second compressor 4.Under fuel oil pattern, refrigeration
As legacy system, compressor is driven and provides power system by caravan engine.Under electric model, system is totally independent of caravan
Engine, directly worked by externally fed.I.e. caravan uses fuel oil pattern in the process of running, but at parking (parking, encamping)
Engine can be then closed, is powered completely by external power source, i.e., is worked under electric model.
In the present invention, increase an electrically-driven compressors in caravan air-conditioning system, and electrically-driven compressors and caravan are empty
It is parallel-connection structure in refrigeration systems to adjust compressor (caravan carries compressor), and two kinds of compressors share other in refrigeration system
Critical piece, including condenser 204, front evaporator 201, finisher 202, expansion valve 203, liquid storage bottle 205 and cooling system
Pipeline etc..Each system refrigeration oil can normally be returned to compressor during to ensure either mode work, be that each compressor is independent
Loop will not be lost in and go to the wrong way with an oil, while for refrigerant when avoiding the both of which from working independently, increase is more in system
Individual unidirectional cutoff valve controls fluid trend.Because the condensation fan in system and evaporation fan are common component, so in fuel oil
Under pattern, blower fan electric power is supplied by automobile current generator and storage battery, and under electric model, blower fan electric power is supplied by external power source.Appoint
When wait, system can only select a kind of pattern to work, and both of which is mutex relation.
The specific embodiment of the present invention is described above.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make a variety of changes or change within the scope of the claims, this not shadow
Ring the substantive content of the present invention.In the case where not conflicting, the feature in embodiments herein and embodiment can any phase
Mutually combination.
