Embodiment 1

[0037] The method of the present invention can use the microcomputer to calculate the outlet air temperature, and then determine the outlet air temperature according to the control flow, so that the air outlet mode of the air conditioner can be automatically switched according to blowing the surface, blowing the feet, blowing the surface and blowing the feet, and blowing the window.

[0038] Among them, the calculation formula of the outlet air temperature Tm is as follows:

[0039] Tm=Tin+ATC+BXi

[0040] Among them: Tin is the air inlet temperature; TC is the condensation temperature of the air conditioner; A is a correction constant, the value range is [0,1]; B is a correction constant; Xi is the blower gear, and the corresponding values ​​are X1, X2, X3, X4, X5, X6, X7.

[0041] The specific meanings of various air outlet modes in the present invention are as follows:

[0042] Defog mode: the air flow mode is blowing the window;

[0043] Surface blowing mode: the airflo...

Abstract

The invention discloses a control method of an air outlet mode in an automatic state of an air conditioner and the automobile air conditioner using the control method. The control method comprises thesteps of detecting and determining an airflow mode in the automatic state of the air conditioner, determining the relationship between an air outlet temperature Tm and w and the relationship betweenTm and y when the airflow mode is determined as a two-channel air outlet mode, determining the relationship between the air outlet temperature Tm and z and the relationship between Tm and x when the airflow mode is determined as a blowing-face mode, determining the relationship between the air outlet temperature Tm and z and the relationship between Tm and y when the airflow mode is determined asa defogging mode, and determining the relationship between the air outlet temperature Tm and w when the airflow mode is determined as a blowing-foot mode, wherein w, x, y, z are preset values of the air outlet temperature and w > x > y > z. The control method of the air outlet mode in the automatic state of the air conditioner and the automobile air conditioner using the control method only utilize an existing temperature sensor, and save the cost of arranging an air outlet temperature sensor. The human body comfort is improved by virtue of the control of the air outlet mode in the automatic mode of the air conditioner.

Description

technical field [0001] The invention belongs to the technical field of automobile air conditioners, and in particular relates to a control method for an air outlet mode of an air conditioner, in particular to a control method for an air outlet mode of an air conditioner in an automatic state. Background technique [0002] At present, the automatic air-conditioning system of automobiles gradually replaces manual air-conditioning and is widely used in the automotive field. Different from the heating method of traditional fuel vehicles, electric vehicles rely on heat pumps for heating in winter. The corresponding automatic air-conditioning system method is also very different from the control of fuel vehicles. [0003] There is no air outlet temperature sensor in the automobile air conditioning system, and the signal of the air temperature cannot be directly recognized. If the air outlet temperature sensor is added, the corresponding cost will be increased. A control method is n...
