Background technology
The exhaust emissions of vehicle is the principal element of atmospheric contamination.The city with high density vehicle is particularly outstanding.In the past few years for improving exhaust emission, various places government launches respectively various preferential policy to promote that environmental protection vehicle develops.
Pure Electric Transit big bus is a kind of environmental protection vehicle of zero-emission, and obtain big or middle city and generally approve, development prospect is wide.
Because the transmission of electric energy is convenient, the power of its compressor no longer needs driving engine directly to provide, and therefore becomes motor driven compressor.
At present, the whole dependence on import of electric bus air-conditioning compressor or foreign capital affiliate manufacture.Its structure is electrical motor direct connection compressor, with the direct cool motors stator and rotor of refrigerant return-air; Compressor arrangement is vortex.Its feature: 1, integral structure is long; 2, expensive; 3, scroll compressor reasons in structure refrigerating capacity is less, has certain limitation to the traveling comfort of automobile; 4, rotating speed is high, noise is large.
Utility model content
The a/c system of the Electric Transit big bus that the purpose of this utility model is to provide a kind of compact conformation, noise is little, safety performance is high.
For achieving the above object, the technical scheme that the utility model adopts is:
An a/c system for Electric Transit big bus, comprises motor driven compressor, condenser, evaporator, and motor driven compressor is connected with condenser, evaporator respectively by four-way change-over valve, meanwhile, is connected with expansion valve between condenser and evaporator; Described motor driven compressor comprises electrical motor arranged in parallel and compressor, is with is connected between the main shaft mouth of electrical motor and the main shaft input end of compressor by PK; The casing of electrical motor offers free air diffuser, and free air diffuser is looped around the stator exterior of electrical motor, one end of free air diffuser and the casing ft connection of electrical motor, and the other end of free air diffuser is communicated with the swash plate chamber in compressor, piston compression chamber successively; The casing of compressor offers exhaust passage, one end of exhaust passage and the casing ft connection of compressor, the other end of exhaust passage is communicated with piston compression chamber; In integral structure between the casing of electrical motor and the casing of compressor.
As the further setting of such scheme, described electrical motor is thulium permanent magnetism gear.Thulium permanent magnetism gear is lightweight, efficiency is high, and efficiency can reach about 95%, and can facilitate and change motor speed as required, to reach the object of compressor " change discharge capacity ".
Described compressor is oblique tray type compressor.Oblique tray type compressor can choose arbitrarily required discharge capacity in the broad range of 100 to 500ml/r.The main shaft of oblique tray type compressor rotates, and makes the swash plate be anchored on main shaft promote piston and make axially reciprocating in piston compression chamber, complete the compression to refrigerant.Be characterized in that compact conformation, noise are little, it is little to vibrate; And Volumetric efficiency during slow speed of revolution is high.
The a/c system of the utility model Electric Transit big bus mainly contains following beneficial effect:
1. the electrical motor in motor driven compressor and compressor arranged in parallel, and in integral structure between the casing of electrical motor and the casing of compressor, make motor driven compressor compact conformation, and then make the structure of whole a/c system more compact.
2. the electrical motor in motor driven compressor is connected with being with by PK between compressor, reduces rotational noise, thus makes the noise reduction of whole a/c system.
3. well-known, electrical motor needs cooling, general motor driven compressor is directly passed between the rotor of electrical motor and stator by refrigerant return-air (containing refrigerant oil), make iron core, permanent magnet, particularly coil long period of soaking is in refrigerant gas and refrigerant oil, be the hidden danger of electrical motor, likely cause serious consequence.Motor driven compressor in the utility model then have employed motor stator exocoel cooling technology, make refrigerating agent containing oil and stator, rotor, coil completely isolated, add reliability and the safety of electrical motor use, thus improve the safety performance of whole a/c system.
4. freeze, heat aspect: original automobile air conditioner compressor is single cooled, heats, and is to be heated by the heat of engine cooling water; The power of existing pure electric bus automobile becomes electrical motor from driving engine, and can not lean on the waste heat of driving engine to have heated; Motor driven compressor in the utility model heats by four-way change-over valve realization, refrigerating function.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
