Refrigerating plant is cooled down or dehumidified for the air in automobile or the fresh air sucked in, so as to obtain the dress of comfort air
Put.Caused low-temperature low-pressure refrigerant steam in evaporator is sucked and is compressed during thermantidote compressor operation, in height
Discharged in the state of warm high pressure.Refrigerant absorbs heat in evaporator is vaporized into gaseous refrigerant, declines evaporator surface temperature.
The air come from air blower, constantly flows through evaporator surface, is sent to after cooled in compartment, compartment is cooled.Modern Car
Heater is used as thermal source by the use of the cooling water of engine.When air conditioning for automobiles works, the air of feeding first passes around evaporator, quilt
After cooling, by temperature damper, portion of air flows to the heat exchanger of heater, is heated；Separately partly flow directly into.It is logical
The position-adjustable for overregulating B air doors enters the AIR Proportional of heat exchanger, has finally just obtained driver when air mixes
The temperature of setting.
But existing car air conditioner cooling system test-bed is complicated, and the course of work is cumbersome, detection inconvenience, security
It is relatively low.
The content of the invention
The defects of the present invention seeks to exist for prior art, provides a kind of experiment of electric automobile air conditioner refrigeration system
Stand.
The present invention to achieve the above object, adopts the following technical scheme that：A kind of experiment of electric automobile air conditioner refrigeration system

Output end is connected with electric machine controller, and the first output end of the electric machine controller connects with synchronous three-phase alternating current motor compressor
Connect, the second output end of the electric machine controller is connected with conditioning control unit；Second output end of the D.C. regulated power supply
It is connected with DC/DC modular converters, the first output end of the DC/DC modular converters is connected by air-conditioning switch and conditioning control unit
Connect, the second output end of the DC/DC modular converters is connected with normally opened relay, the 3rd output of the DC/DC modular converters
End is connected with blower switch, and the output end of the blower switch is connected with blower motor；Wherein, the air-conditioning switch with
Evaporator temperature switch, low tension switch and high-voltage switch gear are additionally provided between the conditioning control unit.
Further, air blower speed adjusting resistance is provided with the blower switch.
Further, in addition to the cooling fan motor for being cooled down to evaporator, the cooling fan motor have
The normally opened relay controls work.
Beneficial effects of the present invention：The present invention can intuitively show the structure and the course of work of electric automobile air conditioner, structure letter
It is single, safe and reliable, it is easy to detect.
Brief description of the drawings
Fig. 1 is the principle schematic diagram of the present invention.
Embodiment
Shown in Fig. 1, it is related to a kind of experimental stand of electric automobile air conditioner refrigeration system, including for 220V alternating currents to be turned
The D.C. regulated power supply 1 of 48V direct currents is changed to, the first output end of the D.C. regulated power supply 1 is connected with electric machine controller 14,
First output end of the electric machine controller 14 connects with synchronous three-phase alternating current motor compressor 13, the electric machine controller 13
Second output end is connected with conditioning control unit 4；Second output end of the D.C. regulated power supply 1 connects with DC/DC modular converters 2
Connect, the first output end of the DC/DC modular converters 2 is connected by air-conditioning switch 3 with conditioning control unit 4, and the DC/DC turns
Second output end of mold changing block 2 is connected with normally opened relay 8, and the 3rd output end of the DC/DC modular converters 2 is opened with air blower
10 connections are closed, the output end of the blower switch 10 is connected with blower motor 12；Wherein, the air-conditioning switch 3 with it is described
Evaporator temperature switch 5, low tension switch 6 and high-voltage switch gear 7 are additionally provided between conditioning control unit 4.
In wherein further scheme, air blower speed adjusting resistance 11 is provided with the blower switch 10.
During work, 220V alternating currents are converted into 48V direct currents and powered to electric machine controller by D.C. regulated power supply.DC/
48V direct currents are converted into 12V DC electricity by DC modular converters.Evaporator temperature switch is arranged near evaporator, for detecting
Evaporator surface temperature, its switch closure at more than 0 DEG C, it is switched off at less than 0 DEG C, and its effect is to prevent evaporator surface
Freeze.Low tension switch and high-voltage switch gear are all on the pressure duct of refrigeration system, when system pressure is less than 0.2MPa, low
