example 1

[0111] Example 1: If figure 2 As shown, in the standby state or in the natural wind mode, when the temperature adjustment knob is turned right by one gear, the expected effect is to adjust the system to the heating mode of +1 heating level, but because the brake is not pressed Hot starter, the operation judgment is invalid, and the system still maintains the state of natural air supply. Then, when the temperature adjustment knob is turned left by one gear, the expected effect is to turn off the heating mode of the +1 heating level of the system, and the system still maintains the state of natural air supply.

[0112] This design is intended to avoid the waste of energy caused by passengers operating the temperature control parts too casually, thereby avoiding the reduction of driving mileage.

example 2

[0113] Example 2: If image 3 As shown, in the standby state or in the natural wind mode, when the temperature adjustment knob is turned right by six gears, the expected effect is to adjust the system to the heating mode of the maximum heating level, but because the heating is not pressed Activator, the operation judgment is invalid, and the system still maintains the state of natural air supply. Then, when the temperature adjustment knob is turned left to the sixth gear, the expected effect is to turn off the heating mode of the maximum heating level of the system, and the system still maintains the state of natural air supply.

[0114] This design is intended to avoid the waste of energy caused by passengers operating the temperature control parts too casually, thereby avoiding the reduction of driving mileage.

example 3

[0115] Example 3: If Figure 4 As shown, in the standby state or in the natural wind mode, when the temperature adjustment knob is turned rightward to the seventh gear and above, the angle of rotation exceeds the starting gear on the hot air side. The intention of the passenger is clear, and the desired effect of the passenger is to adjust the system Heating mode to maximum heating level. At this time, the operation judgment is valid, and the system starts the heating mode at the maximum heating level.

[0116] Since the maximum heating level of the system is level 4, the heating level remains at level 4 when the temperature adjustment knob is turned to the left at a small angle, and the heating level decreases when the temperature adjustment knob is turned to the +3 level.

[0117] In addition, in the standby state, when the temperature adjustment knob is turned rightward from 0 to the seventh gear and above, the wind speed is at the third gear; in the natural wind mode, whe...

Abstract

The invention discloses a control method for an air conditioning system of an electric automobile. The air conditioning system comprises a compressor, a heater and a draught fan and has a standby state and a working state. In the working state, the air conditioning system has a refrigerating mode, a heating mode, a natural air mode and a defrosting mode. In the refrigerating mode, the compressor runs, and the heater is stopped; in the heating mode, the compressor is stopped, and the heater runs; in both the refrigerating mode and the heating mode, the draught fan runs so as to blow refrigerated or heated air into a cab of the electric automobile; in the natural air mode, both the compressor and the heater are stopped, and the draught fan runs to blow air; and in the defrosting mode, both the compressor and the heater are started to run. According to the control method, the energy consumption of the electric automobile and the running cost of the system are reduced, the weight of a storage battery can be better reduced, and miniaturization and lightweight development of the electric automobile are further facilitated.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a control method for an air conditioning system of the electric vehicle. Background technique [0002] The control method of the air conditioner on the electric vehicle is complicated, which is not conducive to reducing energy consumption and saving energy. Contents of the invention [0003] The present application is intended to solve at least one of the problems existing in the prior art. Therefore, the present invention aims to provide a control method of an air-conditioning system of an electric vehicle, according to which the energy consumption can be reduced. [0004] According to the control method of the air-conditioning system of an electric vehicle in an embodiment of the present invention, the air-conditioning system includes a compressor, a heater, and a fan, and the air-conditioning system has a standby state and a working state, and in the working state, the air-...
