Specific embodiment
Below with reference to drawings and examples, the technical solution for the automotive air-conditioning system that one aspect of the invention proposes is made
It is described in further detail.
Refering to Figure 1, the automotive air-conditioning system that an embodiment proposes according to the present invention comprising control module
10, internal-external cycle throttle 11, air blower 12, evaporator 13, humidity detector 14, temperature damper 15 and air-out mode air door
16.Wherein, the humidity detector 14 is configured for detecting the humidity of 13 core surface of evaporator and obtain corresponding
Humidity data, the control module 10 connects the humidity detector 14, and obtains it from the humidity detector 14
The humidity data detected.
Wherein, the humidity detector 14, which specifically can be using humidity sensor, realizes to 13 core of evaporator
The detection of body surface surface humidity.For example, electric resistance moisture sensor, capacitance type humidity sensor or light formula humidity sensor,
But not limited to this.
Preferred light formula humidity sensor in one embodiment, based on principle be light reflection, the biography
Sensor itself is with light transmitting and light receiver unit.When 13 core surface of evaporator is there are when subtle droplet, then
There can be the phenomenon that refraction and reflection of light, the light intensity received so as to cause the sensor changes.The biography
The volume of sensor can enable it to the droplet for detecting very little with very little, for example, the droplet that human eye can't see.
Include humidity sensor signal Acquisition Circuit in the control module 10, is obtained for acquiring the humidity sensor
Humidity Detection data.Moreover, the control module 10 be also configured for controlling the air blower 12 and each air door 11,
15,16 mode position setting.Wherein for the control of the mode position of each air door 11,15,16, can be by controlling air door
11,15,16 respective driving motor, to control the position of air door different mode, but not limited to this.
It should be appreciated that the control module 10 can integrate in place vehicle for manual car air-conditioning system
In car body control module, to improve popularization and use range of the invention.
When work, please refer to shown in Fig. 2, the control module 10 place vehicle stall for a period of time after, for example, 10 points
Zhong Hou, specifically can with the need depending on, and be not limited, just start dehumidification operation.At this moment interior generally to there will be no people, to avoid
Influence of the dehumidification operation to client's comfort.
The control module 10 acquires the Humidity Detection numerical value of the humidity sensor, first by collected detection numerical value
It is compared with preset value in it.When collected Humidity Detection numerical value is greater than preset value, the evaporator 13 is judged
Core surface has the demand of dehumidifying；Otherwise, then judge that the core surface of the evaporator 13 does not have dehumidification.
Then, the size of vehicle battery voltage value where the control module 10 needs to judge, to comprehensively consider to institute
The dehumidification operation of 13 core surface of evaporator is stated, the influence that consumed place vehicle battery electricity starts vehicle.Such as
Battery voltage value described in fruit is lower than the voltage value of place whole vehicle engine start, for example, 11.5V(but not limited to this, only
Illustrate for illustrative), then the control module 10 does not start the air blower 12 and carries out removing for 13 core surface of evaporator
Wet practice.
Further, when the air blower 12 operates, to guarantee that it is empty that it blows to 13 core surface of evaporator
Gas be all it is dry, be preferably provided with the internal-external cycle throttle 11 in outer circulation mode position.
For the circulation for reinforcing in-vehicle air, humid air is discharged outside vehicle as early as possible, is preferably provided with the air-out mode air door 16
In blowing face air-out mode position.The setting of this mode is related with vehicle flow field analysis result, if vehicle flow field analysis is found
Defrosting air-out mode is more advantageous to the discharge of interior humid air, then air-out mode air door 16 can be placed in defrosting air-out mode position
It sets.To reduce in the 13 core surface dehumidification process of evaporator, the influence to heater core can incite somebody to action in the process
The temperature damper 15 is placed in full cold mode position.
Finally, the control module 10 controls the air blower after 13 core surface of evaporator dehumidifying is completed
12 close, while controlling each air door 11,15,16 and also returning to the position before 13 core surface of the evaporator dehumidifying.
The automotive air-conditioning system that one aspect of the invention proposes, A/C evaporator core is accurately detected by humidity sensor
Then the humidity in body surface face is carrying out effective dehumidification operation to it by air blower, to effectively overcome expansion core
The problem of body is big and mouldy because of humidity, leads to air-conditioning peculiar smell improves the riding comfort and satisfaction of client.Meanwhile also
Energy conservation can be taken into account, the fuel economy of vehicle where being promoted.
Moreover, before dehumidification operation, vehicle battery voltage value where the system also detects, if the storage of place vehicle
Cell voltage is lower than the voltage of engine starting, then does not start air blower and be evaporated the dehumidifying of device core surface, to keep away
Exempt from the influence that vehicle battery electricity where consuming excessively starts vehicle.
Also, air blower used in the air conditioning for automobiles, air conditioner damper and associated mechanical air door, in the sky of existing vehicle
It is all configured in adjusting system, it does not need to be modified, not will increase additional cost, be more convenient for that the present invention relates to air-conditioning systems
The popularization and use of system.
Technical scope of the invention is not limited solely to the content in above description, and those skilled in the art can not take off
Under the premise of from technical thought of the invention, many variations and modifications are carried out to above-described embodiment, and these deformations and modification should all
In belonging to the scope of protection of the present invention.
