4th, rotating speed is high, noise is big.
The content of the invention
It is an object of the invention to provide a kind of compact conformation, the air-conditioning of the Electric Transit bus that noise is small, security performance is high
System.
To reach above-mentioned purpose, the technical solution adopted in the present invention is：
A kind of air-conditioning system of Electric Transit bus, including motor compressor, condenser, evaporator, motor compressor lead to
Four-way reversing valve is crossed to be connected with condenser, evaporator respectively, meanwhile, expansion valve is connected between condenser and evaporator；It is described
Motor compressor includes motor and compressor arranged in parallel, and the main shaft output end of motor is defeated with the main shaft of compressor
To enter connected by PK bands between holding；Inlet channel is offered on the casing of motor, inlet channel is looped around the stator of motor
Outside, one end of inlet channel and the casing ft connection of motor, the other end of inlet channel successively with compressor in it is oblique
Disk chamber, the connection of piston compression chamber；Exhaust passage, one end of exhaust passage and the casing of compressor are offered on the casing of compressor
Ft connection, the other end of exhaust passage is connected with piston compression chamber；It is in one between the casing of motor and the casing of compressor
Body formula structure.
As the further setting of above-metioned scheme, the motor is thulium permanent magnetism gear.Rareearth permanent-magnet DC
Motor weight is light, efficiency high, and efficiency can reach 95% or so, and conveniently can as needed change motor speed, to reach compression
The purpose of machine " change discharge capacity ".
The compressor is oblique tray type compressor.Oblique tray type compressor can be any in the broad range of 100 to 500ml/r
Discharge capacity needed for choosing.The main shaft rotation of oblique tray type compressor, makes to be anchored on the swash plate on main shaft and promotes piston in piston compression chamber
Inside make axially reciprocating, complete the compression to refrigerant.It is characterized in that compact conformation, noise be small, vibration is small；And the slow-speed of revolution
When volumetric efficiency it is high.
The air-conditioning system of Electric Transit bus of the present invention mainly has following beneficial effect：
1. the motor and compressor in motor compressor are arranged in parallel, and casing and the compressor of motor case
It is in integral structure between body, makes motor compressor compact conformation, and then cause that the structure of whole air-conditioning system is more compact.
2. connected by PK bands between the motor and compressor in motor compressor, reduce rotational noise, so that
Obtain the noise reduction of whole air-conditioning system.
3., it is well known that motor needs cooling, general motor compressor is by refrigerant return-air（Containing refrigeration oil）Directly
It is passed through between the rotor of motor and stator, makes iron core, permanent magnet, particularly coil long period of soaking is in refrigerant gas and freezing
It is the hidden danger of motor, it is possible to cause serious consequence in oil.And the motor compressor in the present invention then employs motor stator
Sub- exocoel cooling technology, makes refrigerating agent containing oil completely isolated with stator, rotor, coil, increased the reliability that motor is used
And security, so as to improve the security performance of whole air-conditioning system.
4. freeze, heat aspect：Original automobile air conditioner compressor is single cooled, and is heated, and is by starting
The heat of machine cooling water is heated；The power of existing pure electric bus automobile is changed into motor from engine, and can not be by starting
The waste heat of machine is heated；Motor compressor in the present invention can be heated by four-way reversing valve realization, refrigerating function.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Brief description of the drawings
