The specific embodiment
Understand for technical characterictic, purpose and effect to utility model have more clearly, now contrast the description of drawings specific embodiment of the present utility model, identical label is represented identical part in each figure.
Fig. 1 is the scheme drawing of a kind of embodiment of electric vehicle air conditioning system.As shown in Figure 1, electric vehicle air conditioning system comprises an inverter 12 that links to each other with the automobile batteries 10 of electronlmobil; An air-conditioning compressor 20 that links to each other with inverter 12.Air-conditioning compressor 20 can be frequency converting air-conditioner compressor.The refrigerant of air-conditioning compressor 20 outputs returns described air-conditioning compressor 20 through condenser 22, liquid storage dryer 24, expansion valve 26 and crew department's evaporator 28.
It is air-conditioning compressor 20 power supplies that the direct current (DC) of automobile batteries 10 becomes alternating current through inverter 12, drive air-conditioning compressor 20 rotations, the refrigerant of output high temperature, high-voltage gas, refrigerant enters condenser 22 and cools off, because the outer temperature of car is lower than the refrigerant temperature that enters condenser 22, a large amount of heats of the refrigerant in condenser are taken away by the car outer air, thereby the condensation of refrigerant of high temperature, high-voltage gas becomes the refrigerant of high temperature, highly pressurised liquid.This refrigerant process liquid storage dryer 24, liquid storage dryer 24 interim storages from the refrigerant of the liquid of condenser outflow, when little leakage took place, the amount of the refrigerant of expansion valve 26 was supplied with in energy supplementary sum adjustment in time, and assurance refrigerant continous-stable flows.When high temperature, high-voltage liquid refrigerant enter expansion valve 26, volume becomes big step-down suddenly, and the refrigerant that becomes low temperature, low pressure enters evaporator, vaporizes under level pressure, thereby the air themperature of the evaporator of flowing through is reduced, and produces the effect of refrigeration cool-down.The refrigerant of having vaporized is from newly entering the gas refrigerant that compressor becomes High Temperature High Pressure, constantly circulation.
Electric automobile air-conditioning system also comprises an air-conditioner controller 30, reception is from the evaporator temperature signal of crew department's temperature signal of electronlmobil, crew department's evaporator 28 and the target temperature signal of being set by a temperature setting device 32, and according to the control signal of these signal outputs to air-conditioning compressor 20.By air-conditioner controller 30 target setting temperature, the sensor (not shown) in the air-conditioner controller 30 obtains crew department's temperature signal, air-conditioner controller 30 with the target temperature signal of this temperature signal and setting jointly as target temperature.The sensor (not shown) of evaporator 28 obtains the evaporator temperature signal.According to the evaporator feedback temperature, air-conditioner controller 30 control air-conditioning compressor 20 and evaporators 28, the power of control air-conditioning compressor 20 and evaporator 28, low cruise in the low no cooling ability of temperature of electronlmobil air-conditioning, the power consumption of minimizing system.
As shown in Figure 2, in a kind of exemplary embodiment of the present utility model, condenser 22 also is provided with a cooling fan 21, and air-conditioner controller 30 is also exported the control signal to cooling fan 21.Cool off when refrigerant enters condenser 22, by means of cooling fan 21 effects, a large amount of heats of the refrigerant in condenser are taken away by the car outer air, thereby the condensation of refrigerant of high temperature, high-voltage gas becomes the refrigerant of high temperature, highly pressurised liquid.
Crew department's evaporator 28 also is provided with a fan 29, and air-conditioner controller 30 is also exported the control signal to fan 29.Controller 30 is controlled fan 29 according to Current Temperatures and target temperature.Fan 29 can be the PWM fan, controls air-conditioning compressor 20 and evaporator 28 power accurately, avoids low cruise in the low no cooling ability of temperature of electric automobile air-conditioning system, reduces the power consumption of system.
Fig. 3 is used to illustrate the working process of electric automobile air-conditioning system, and as shown in Figure 3, the working process of electric automobile air-conditioning system is as follows.
Carry out system initialization at step S10.
At step S12, air-conditioner controller 30 judges whether to satisfy the service conditions of electric automobile air-conditioning system, if the service conditions of electric automobile air-conditioning system can't satisfy, then program enters step S20, air-conditioner controller 30 automatic power cut-off processes are avoided system power dissipation.
If satisfy the service conditions of electric automobile air-conditioning system, then enter step S14, controller 30 calculates the amount of refrigerant, air-conditioning compressor 20 rotating speeds in step S16 control electric air-conditioning system subsequently, judge the state of fan 29 at step S18, the rotating speed of unified refrigerant amount, air-conditioning compressor 20 is when target temperature reaches, in step S20 power cut-off process.
Above listed a series of detailed description only is specifying at feasibility embodiment of the present utility model; they are not in order to limiting protection domain of the present utility model, allly do not break away from equivalent embodiment or the change that skill spirit of the present invention done and all should be included within the protection domain of the present utility model.
