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 automobile air conditioner inner and outer circulation modes. The control method comprises the steps that the working mode of an air conditioner system is detected; the state of a compressor is detected; the air blowing mode of the air conditioner system is detected; the power state of an engine is judged; whether the conditions a, b, c and d are met at the same time or not is judged, if yes, the inner and outer circulation modes are adjusted into the inner mode, and if not, the current circulation modes are kept, wherein the condition a is that the air conditioner system is in the automatic mode, the condition b is that the compressor is in the start state, the condition c is that the air blowing mode is a non-window-blowing mode or a non-window-blowing foot-blowing mode, and the condition d is that the engine is in the power insufficient mode. According to the control method and system for the automobile air conditioner inner and outer circulation modes, the engine is prevented from working with overloads, and the service life of the engine is prolonged.

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...
