Embodiment

[0060] The control method of the internal and external circulation mode of the automobile air conditioner pre-sets the following conditions:

[0061] Condition a: The air conditioning system is in automatic mode;

[0062] Condition b: the compressor is on;

[0063] Condition c: The blowing mode is non-window blowing mode or non-window blowing foot blowing mode;

[0064] Condition d: The engine is in a state of insufficient power.

[0065] Such as figure 1 As shown, the control method of the internal and external circulation mode of the automobile air conditioner, the process of free fine-tuning of the position of the internal and external circulation damper comprises the following steps:

[0066] Get the following data in real time:

[0067] Step1 calculates the fogging probability.

[0068] Step2 detects the engine water temperature.

[0069] Step3 Calculate the heat load of the air conditioning system.

[0070] Step4 detects the speed of the car.

[0071] Step5 detec...

Abstract

The invention relates to a control method and system for an internal and external circulation mode of an automobile air conditioner, including: detecting the working mode of the air conditioner system; detecting the state of the compressor; detecting the blowing mode of the air conditioner system; judging the power state of the engine; , c, d, if conditions a, b, c, and d are met at the same time, the internal and external circulation mode is adjusted to internal circulation, otherwise, the current circulation mode is maintained, among which, condition a: the air conditioning system is in automatic mode; condition b: the compressor is on Status; Condition c: The blowing mode is the non-window blowing mode or the non-window blowing foot-blowing mode; Condition d: The engine is in a power-deficient state. The control method and system for the internal and external circulation mode of the automobile air conditioner provided by the present invention avoid overloading of the engine and prolong the service life of the engine.

Description

technical field [0001] The invention relates to the field of automobile air conditioner control, in particular to a control method and system for the internal and external circulation modes of the automobile air conditioner. Background technique [0002] At present, the air circulation mode of the automobile air-conditioning system includes an internal circulation mode and an external circulation mode. Internal circulation means that the wind blown by the blower only circulates inside the car. Since there is no external air involved, it has the advantages of fuel saving and fast cooling (heating). The disadvantage is that it is not conducive to the renewal of the air in the car. External circulation means that the blower sucks air from the outside of the car and blows it into the car. The advantage is to keep the freshness of the air in the car, but it consumes oil and the cooling (heating) speed is slow. In order to balance the problems of fuel consumption and air quality...
