Control method, device, storage medium and air conditioner controller for electric air conditioner

Abstract

The invention discloses a control method, device, storage medium and air conditioner controller of an electric air conditioner. The method includes: obtaining the actual temperature value of the current water outlet of the heater of the electric air conditioner and the target temperature value corresponding to the heating gear currently used by the heater; The opening of the heating and cooling air door of the electric air conditioner and the heating power of the heater. The invention solves the technical problem in the related art that the heating power of the electric air conditioner and the heating and cooling dampers operate independently of each other and lack linkage.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a control method, device, storage medium and air conditioner controller for an electric air conditioner. Background technique [0002] At present, the heating and cooling dampers of electric air conditioners are usually controlled by operating knobs, and the total travel of the dampers corresponds to the position of the operating mechanism. Each gear position of the operating mechanism corresponds to a fixed position, so the outlet air temperature cannot be flexibly controlled, and the heater is always turned on to the maximum gear, which causes serious power waste and affects the cruising range of the vehicle. The heater distributes the heating power corresponding to each gear evenly according to the gear position of the operating mechanism, and the heating and cooling air door is at the maximum position. After the heater has been heated for a long enough time, the outlet air t...

AI Technical Summary

Problems solved by technology

If the heater is equipped with the automatic control function of the outlet air temperature, when the operating mechanism is adjusted from the maximum heating temperature to the minimum heating temperature, due to the relatively large heat capacity of the coolant, the temperature of the coolant cannot be adjusted to the required temperature immediately, thus affecting the comfort of passengers

In addition, in view of the heater temperature and the fixed position corresponding to the gear adjustment of the operating mechanism corresponding to the heating and cooling air door, if it is necessary to adjust from the highest heating temperature to the minimum heating temperature at this time, the heating and cooling air door should be adjusted in place first, resulting in a significant change in the outlet air temperature

However, as the water temperature of the heater continues to decrease, the temperature of the air outlet will decrease accordingly, which will also affect the comfort of passengers

[0003] It can be seen that the electric heater and the heating and cooling air door of the electric vehicle electric air conditioning system provided in the related art cannot realize linkage control

It is impossible to achieve balance among the considerations of heater water temperature, heating power, position corresponding to the damper, outlet air temperature and heater power

When the outlet air temperature is appropriate, it is impossible to ensure that the heater is in an energy-saving state; and when the heater is in an energy-saving state, it is impossible to ensure the linearity of the outlet air temperature

[0004] For the above problems, no effective solution has been proposed
