Abstract
The utility model discloses a hybrid -driven air conditioning system for excavator belongs to vehicle air conditioner equipment technical field, including condenser (2), reservoir (3), evaporation case (4), condensation fan (1), engine driven compressor (5) and motor compressor (6), engine driven compressor (5) form closed -loop with evaporation case (4), reservoir (3), condenser (2) intercommunication through the pipeline in proper order, and condensation fan (1) sets up in one side of condenser (2), motor compressor (6) are parallelly connected through pipeline and engine driven compressor (5). When parking operation start air conditioner, can not shorten the continuous operating time of vehicle, can not produce carbon monoxide waste gas in the driver's cabin in the air conditioner use in addition, the assurance driver's is healthy.
Description
Technical field
The utility model relates to a kind of a/c system, and specifically a kind of excavating machine combination drive a/c system, belongs to car air-conditioner equipment technical field.
Background technology
The car air-conditioners such as traditional excavating machine, pass through engine belt drive, driving air-conditioning compressor carries out operation of air conditioner, the vehicles such as these excavating machines, hoisting crane, heavily card generally all need (the continuous working every day 12-20 hour) of long continuous operation, when ambient temperature needs to continue to turn on the aircondition cooling higher than 28 DEG C of operator'ies compartment; Existing air-conditioning is all open a/c system by engine drive air-conditioning compressor, air-conditioning horsepower input is up to 3000-4400W, if carry out continuing using air-condition in the process of operation in vehicle non-driving state for a long time, vehicle oil consumption will be caused comparatively large, shorten the work-hours that vehicle carries out disposable continuous working.Using during engine drive operation of air conditioner in vehicle non-driving state in addition causes fuel oil uncomplete combustion can produce carbonic oxide waste gas because vehicle motor idling is lower, it can enter operator's compartment along air-conditioning ventilation inlet, and long-term like this to treat to affect healthy even carbonic oxide waste gas at the chaufeur of airtight driving office work poisoning.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of excavating machine combination drive a/c system, when parking operation start air-conditioning, can not shorten the stream time of vehicle; Carbonic oxide waste gas can not be produced in operator's compartment in air-conditioning use procedure in addition, ensure the healthy of chaufeur.
To achieve these goals, the technical solution adopted in the utility model is: this kind of excavating machine combination drive a/c system, comprise condenser, reservoir, evaporation tank, condensation fan, engine drive compressor and motor driven compressor, engine drive compressor is communicated with evaporation tank, reservoir, condenser is successively formed C/LOOP by pipeline, condensation fan is arranged on the side of condenser, and described motor driven compressor is by pipeline and engine drive compressor parallel.
Further, a check valve is equipped with at the liquid outlet of engine drive compressor and the liquid outlet of motor driven compressor.
Further, the cold finger in described condenser is flat tube.
Compared with prior art, the utility model increases motor driven compressor, have employed combination drive air-conditioning, and adopt engine drive compressor start air-conditioning during using air-condition when driving, now motor driven compressor does not work; When carrying out original place operation after a stoppage, be electrically connected motor driven compressor by city, adopt motor driven compressor to start air-conditioning when using air-condition, now engine drive compressor does not work, additionally would not consume the oil mass of vehicle itself like this, the stream time of vehicle can not be shortened; In addition in air-conditioning use procedure owing to adopting motor driven compressor, make can not produce carbonic oxide waste gas in operator's compartment, ensure chaufeur healthy.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
In figure: 1, condensation fan, 2, condenser, 3, reservoir, 4, evaporation tank, 5, engine drive compressor, 6, motor driven compressor, 7, check valve.
Detailed description of the invention
The utility model is described in further detail below.
As depicted in figs. 1 and 2, the utility model comprises condenser 2, reservoir 3, evaporation tank 4, condensation fan 1, engine drive compressor 5 and motor driven compressor 6, engine drive compressor 5 is communicated with evaporation tank 4, reservoir 3, condenser 2 successively by pipeline and forms C/LOOP, condensation fan 1 is arranged on the side of condenser 2, and described motor driven compressor 6 is in parallel with engine drive compressor 5 by pipeline.
Improve as one of the present utility model, be equipped with a check valve 7 at the liquid outlet of engine drive compressor 5 and the liquid outlet of motor driven compressor 6; Increase check valve 7 at the liquid outlet place of two compressors, can prevent when engine drive compressor 5 or motor driven compressor 6 work, refrigerant return enters in another compressor out-of-run, causes refrigeration to be deteriorated.
Cold finger in described condenser 2 can be pipe, square tube or flat tube, preferably adopts flat tube, and such shape can increase the area of interchange of heat, improves air conditioner refrigeration effect.
Adopt engine drive compressor 5 to start air-conditioning when driving during using air-condition, now motor driven compressor 6 does not work; When carrying out original place operation after a stoppage, by city's electrical connection motor driven compressor 6, adopt motor driven compressor 6 to start air-conditioning when using air-condition, now engine drive compressor 5 does not work, additionally would not consume the oil mass of vehicle itself like this, the stream time of vehicle can not be shortened.
