Embodiment 1

[0014] The musty smell of the air conditioner is caused by the moldy interior of the air conditioner in the car, such as the air outlet and air duct, caused by high humidity such as water vapor in the car air conditioner. This application mainly uses the automatic start of the air conditioner after the vehicle is parked and turned off. The blower is used for dehumidification, and the water and moisture are blown out by means of external circulation, so as to avoid the influence of residual water vapor in the car. Specific programs include:

[0015] A control method for reducing the musty smell of an automobile air conditioner, comprising the steps of:

[0016] Including the detection during the start-up and running of the vehicle and the control after the vehicle is stopped and turned off;

[0017] Real-time detection of air conditioner operating status after the vehicle is started, and judge whether the air conditioner operation status will cause mildew risk; mildew risk ref...

Embodiment 2

[0025] When the vehicle is running, monitor the compressor and outdoor temperature in real time. When the compressor runs for more than 4 minutes and the ambient temperature is ≥10°C, it is judged that there is a risk of mildew. After the vehicle is turned off and stopped for 30mim, start the blower (blower voltage 50 %), external circulation, the blowing mode adopts the state before the flameout, continuous blowing for 10S, stop for 10S, 4 consecutive cycles, to eliminate the condensed water on the surface of the evaporator, so as to achieve the effect of automatically reducing the musty smell.

Abstract

The invention discloses a control method for reducing musty odor of an automobile air conditioner, which comprises the following steps: detecting the running state of the air conditioner in real time after an automobile is started, and judging whether the running state of the air conditioner can generate a mildew risk or not; and if so, controlling the air conditioner to operate in a set state to dehumidify an air conditioner evaporator after the automobile flames out, and turning off the air conditioner after the end condition is met. The method has the advantages that hardware cost does not need to be increased, only software is needed to control the control method to detect and judge operation of the air conditioner, condensate water on the surface of the evaporator is reduced or eliminated by starting an air blower after flameout of the automobile and controlling an air conditioner circulating air mode, mildew caused by the condensate water is reduced, and further, the musty odor is reduced.

Description

technical field [0001] The invention relates to the field of automobile air-conditioning control, in particular to a control method for reducing the musty smell of automobiles. Background technique [0002] With the improvement of people's living standards, the demand for automobiles is not only a means of travel, but also greatly increases the comfort requirements of automobiles. In the survey of historical problems over the years, the main complaints of the air conditioning system basically include: not cooling fast enough, musty smell, and noise. At present, there are three main ways to reduce the musty smell of air conditioners: 1. Change the filter screen frequently; 2. Apply higher quality sealing materials; 3. Reduce the use of foam under the premise of ensuring airtightness. These three schemes are not only costly, but also inconvenient to operate. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior ...
