example 1

[0131] Example 1: If Figure 12 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.

[0132] 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

[0133] Example 2: If Figure 13 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.

[0134] 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

[0135] Example 3: If Figure 14 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.

[0136] 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.

[0137] 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, wh...

Abstract

The invention discloses a control method for an air adjusting system of an electric car. In the refrigerating mode, a compressor is operated while a heater is turned off. In the heating mode, the compressor is turned off while the heater is operated. A fan is operated in both the refrigerating mode and the heating mode so as to blow cooled air or heated air into a cab of the electric car. In the natural wind mode, both the compressor and the heater are turned off, and the fan is operated to blow air. In the defrosting mode, both the compressor and the heater are started for operation. According to the embodiment of the control method for the air adjusting system of the electric car, the power consumption of the electric car and system operation cost are reduced, the weight of a storage battery is advantageously reduced, and miniaturization and lightweight development of the electric car is further facilitated. Fragmentary small display screens on an air conditioner control panel are omitted, and a display screen is used for displaying air conditioner operation information, so that the occupied area of the air conditioner control panel is reduced. In addition, the air adjusting system is simple and attractive in structure and has multiple control functions.

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. [0003] There are many control parts, fragmented small display screens, and control panels that need to be installed on the center console of electric vehicles, and the shapes are different, which will give people a sense of heterogeneity and fragmentation as a whole. For example, the air conditioner control panel will form an irregular shape, and the panel is provided with two or three rows of buttons, keys and two or three small display blocks, etc., which is not conducive to the simple and beautiful design of the interior of the electric vehicle. Contents of the invention [0004] The present application is intended to ...
