Barrier rate is high.
Utility model content
The defects of in order to overcome in the prior art, the purpose of this utility model are to provide a kind of simple and reliable for structure, letter
Number collector is few and precision is high, can thermostatically controlled temp electric automobile air conditioner refrigeration system.
What the purpose of this utility model was realized in：
A kind of electric automobile air conditioner refrigeration system, including the motor compressor assembly being sequentially connected in series, condenser and evaporator,
The motor compressor assembly includes motor, with the compressor controller of motor connection and the control mould of controlled motor rotating speed
Block；The control module includes the main control singlechip being sequentially connected in series, temperature control single-chip microcomputer, analog-digital converter and thermistor, master control
Single-chip microcomputer and motor connection；The thermistor is arranged on the air entry of compressor, is exchanged heat by thermistor induction evaporation mode device
Refrigerant temperature afterwards carrys out regulation motor rotating speed, so as to control the constant temperature effect that electric automobile air conditioner freezes.
The utility model is further arranged to：Expansion valve is provided between the condenser and evaporator.
The utility model is further arranged to：The junction of condenser and motor compressor assembly is provided with exhaust outlet, steams
The junction of hair device and motor compressor assembly is provided with air entry.
The utility model is further arranged to：Be additionally provided with motor compressor assembly high-voltage power supply control system and
12V start stop switches.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：By said structure, refrigeration is reduced
The space of system, while realize the controllable output of motor compressor assembly by control system, make steaming come the rotating speed of controlled motor
The cold wind that hair device comes out keeps steady state value to the temperature of automotive interior.
Brief description of the drawings
Fig. 1 is principle schematic of the present utility model.
Label implication in figure：

Embodiment
The utility model is further described with specific embodiment 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 as to control electric automobile air conditioner system
Cold constant temperature effect, by said structure, the space of refrigeration system is reduced, while by control system come controlled motor 4
Rotating speed, the controllable output of motor compressor assembly 1 is realized, 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 turns into the vaporific hydraulic pressure refrigerant of low-temp low-pressure after the throttle orifice throttling of expansion valve 11, 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, reduces the temperature of in-car.Expansion valve 11 controls the flow of refrigerant, and the outlet for ensureing 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 finishes, and causes refrigeration deficiency.
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
14 are closed, the convenient opening and closing to system.
During work, after thermistor 9 senses the temperature at air entry 10, analog-digital converter 8 is by the signal of thermistor 9
Binary speed signal is converted to, is transmitted to temperature control single-chip microcomputer 7, 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, controlled the flow rate of refrigerant gas into condenser 2, so as to control changing for evaporator 3
Heat, the temperature of air-conditioner air outlet is always maintained at comfortably, and then change the sensing amount of thermistor 9.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection model of the present utility model according to this
Enclose, therefore：All equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by protection of the present utility model
