Description
Technical field
The utility model belongs to car air-conditioner technical field, and in particular to a kind of dual power source air conditioning system for vehicle.
Background technology
Special purpose vehicle is commercially using more and more.The other work of many times car parking progress (such as blood-collecting car,
Caravan etc.), but remain that air-conditioning works on, at this time if car still open engine drive compressor of air conditioner and
Generator drive air-conditioning work, then not only bring the uneconomical of fuel economy, the increase of use cost can also be with noise
Increase, the increase of pollution, the increase of peculiar smell, can have an impact the comfort of people.
Utility model content
A kind of the defects of the utility model is in order to make up the prior art, there is provided dual power source air conditioning system for vehicle.
The utility model is achieved by the following technical solution：
A kind of dual power source air conditioning system for vehicle, including indoor apparatus of air conditioner become with air-conditioner outdoor unit assembly and AC-DC voltages
Change device, the indoor apparatus of air conditioner is parallel with the first compressor and the second compression with air-conditioner outdoor unit assembly by air conditioner connecting pipe road
Machine, indoor apparatus of air conditioner access 220V alternating currents with air-conditioner outdoor unit assembly by AC-DC voltage changes device.
Further, it is respectively equipped with the suction line and gas exhaust piping of first compressor and the second compressor unidirectional
Valve, during preventing that the wherein compressor from working, refrigerant and lubricating oil are brought into another compressor.
Further, second compressor is connected with motor by belt.Motor uses AC220V alternating current conducts
Power resources.
Further, the AC-DC voltage changes device is connected in parallel on the circuit system of indoor apparatus of air conditioner and air-conditioner outdoor unit assembly
On, common AC220V AC conversions are become into 24V direct currents supply air-conditioning draught fan.
The beneficial effects of the utility model are：A kind of dual power source air conditioning system for vehicle of the utility model ensures heat pump performance
On the premise of use, increase another power source of air-conditioning to ensure that bus engine remains able to normal use sky after stopping
Adjust.
Brief description of the drawings
The utility model will be further described below with reference to the accompanying drawings.
Attached drawing 1 is the structure diagram of the utility model；
Attached drawing 2 is the Parallel connection structure schematic diagram of each compressor of the utility model；

Attached drawing 4 is the power resources schematic diagram of the utility model air-conditioning draught fan.
In figure, 1 indoor apparatus of air conditioner and air-conditioner outdoor unit assembly, 2AC-DC voltage change devices, 3 air conditioner connecting pipe roads, 4 the
One compressor, 5 second compressors.
Embodiment
Attached drawing 1-4 is a kind of specific embodiment of the utility model.A kind of dual power source car air-conditioner system of the utility model
System, including indoor apparatus of air conditioner and air-conditioner outdoor unit assembly 1 and AC-DC voltage changes device 2, the indoor apparatus of air conditioner with outside air conditioning chamber
Machine assembly 1 is parallel with the first compressor 4 and the second compressor 5 by air conditioner connecting pipe road 3, indoor apparatus of air conditioner with outside air conditioning chamber
Machine assembly 1 accesses 220V alternating currents by AC-DC voltage changes device 2.
Further, it is respectively equipped with unidirectionally on the suction line of 4 and second compressor 5 of the first compressor and gas exhaust piping
Valve, during preventing that the wherein compressor from working, refrigerant and lubricating oil are brought into another compressor.
Further, second compressor 5 is connected with motor by belt.Motor is made using AC220V alternating currents
For power resources.
Further, the AC-DC voltage changes device 2 is connected in parallel on the system electricity of indoor apparatus of air conditioner and air-conditioner outdoor unit assembly 1
Lu Shang, becomes 24V direct currents supply air-conditioning draught fan by common AC220V AC conversions.
A kind of dual power source air conditioning system for vehicle of the utility model, directly drives the first pressure during use by engine
Contracting machine 4 is air-conditioning work, and engine directly drives vehicle-mounted 24VDC generators and is used as the first power source for air-conditioning draught fan work,
Then the second compressor 5, auxiliary AC-DC voltage changer driving air-conditioning draught fan work are driven with the civilian ac motors of 220VAC
It is used as the second power source, solves following three major issues by the technical program：1st, since double-compressor is relation in parallel,
After the work of a wherein compressor, lubricating oil inside the refrigerant and compressor of generation can to another compressor of compressor into
Row interference, influences its service life；2nd, the type of drive of the second compressor 5 is machine driving, need to solve power resources；3rd, when
Parking, when air-conditioning need to be used by stopping paying out motivation, the power resources problem of the 24V wind turbines of air-conditioning.
The utility model is not limited to the above embodiment, anyone should learn what is made under the enlightenment of the utility model
There is same or like technical solution with the utility model, each fall within the scope of protection of the utility model.
Technology that the utility model is not described in detail, shape, construction part are known technology.
