Refrigerant temperature afterwards carrys out regulation motor rotating speed, so as to control the constant temperature effect that electric automobile air conditioner freezes.
The present invention is further arranged to：Expansion valve is provided between the condenser and evaporator.
The present invention is further arranged to：The junction of condenser and motor compressor assembly is provided with exhaust outlet, evaporator
The junction of motor compressor assembly is provided with air entry.
The present invention is further arranged to：High-voltage power supply control system is additionally provided with motor compressor assembly and 12V is opened
Guard's valve.
The present invention is prominent and beneficial compared with prior art to be had the technical effect that：By said structure, refrigeration system is reduced
Space, while realizing the controllable output of motor compressor assembly come the rotating speed of controlled motor by control system, making evaporator
The cold wind come out keeps steady state value to the temperature of automotive interior.
Brief description of the drawings

Embodiment
With specific embodiment, the invention will be further described below in conjunction with the accompanying drawings：
It is shown in Figure 1, a kind of electric automobile air conditioner refrigeration system, including the motor compressor assembly 1 being sequentially connected in series, it is cold
Condenser 2 and evaporator 3, the motor compressor assembly 1 include motor 4, the compressor controller 5 being connected with motor 4 and control
The control module of the rotating speed of motor 4 processed；The control module includes the main control singlechip 6 being sequentially connected in series, temperature control single-chip microcomputer 7, modulus
Converter 8 and thermistor 9, main control singlechip 6 are connected with motor 4；The thermistor 9 is arranged on the air entry of evaporator 3
10, by the stabilization of the gas outlet of 9 induction evaporation mode device of thermistor 3 come the rotating speed of regulation motor 4, so that the electric automobile air conditioner system of control
Cold constant temperature effect, by said structure, reduces the space of refrigeration system, while by control system come controlled motor 4
Rotating speed, realizes the controllable output of motor compressor assembly 1, the cold wind that evaporator 3 comes out is protected the temperature of automotive interior
Hold steady state value.
It is further arranged to：Expansion valve 11, the liquid system of cryogenic high pressure are provided between the condenser 2 and evaporator 3
Cryogen is after the throttle orifice throttling of expansion valve 11, and the vaporific hydraulic pressure refrigerant as low-temp low-pressure, is the evaporation of refrigerant
Create conditions；Meanwhile, into the liquid refrigerant of evaporator 3, after evaporator 3, refrigerant is evaporated to gaseous state by liquid, inhales
Heat is received, in-car temperature is reduced.Expansion valve 11 controls the flow of refrigerant, it is ensured that the outlet of evaporator 3 is entirely gaseous state system
Cryogen, if flow is excessive, outlet contains liquid refrigerant, and liquid hammer is produced possibly into compressor；If refrigerant flow is too small, carry
Front evaporator is finished, and causes refrigeration not enough.
It is further arranged to：The junction of condenser 2 and motor compressor assembly 1 is provided with exhaust outlet 12, evaporator 3 with
The junction of motor compressor assembly 1 is provided with air entry 10；Gas is realized by the setting of exhaust outlet 12 and air entry 10
Circulation it is smooth.
It is further arranged to：High-voltage power supply control system 13 is additionally provided with motor compressor assembly 1 and 12V start and stop are opened
Close 14, the convenient opening and closing to system.
During work, thermistor 9 is sensed after the temperature at air entry 10, and analog-digital converter 8 is by the signal of thermistor 9
Binary speed signal is converted to, temperature control single-chip microcomputer 7 is transmitted to, temperature control single-chip microcomputer 7 is transmitted to main control singlechip 6, passes through master control monolithic
The rotating speed of the controlled motor 4 of machine 6, is controlled the flow rate of refrigerant gas into condenser 2, so as to control changing for evaporator 3
Heat, makes the temperature of air-conditioner air outlet be always maintained at comfortably, and then changes the sensing amount of thermistor 9.
Above-described embodiment is only presently preferred embodiments of the present invention, is not limited the scope of the invention according to this, therefore：It is all according to
The equivalence changes that structure, shape, the principle of the present invention is done, all should be covered by within protection scope of the present invention.
