In order to save fuel, ECO mode was turned on, and the air conditioner was broken?

It is said that car use in summer must be inseparable from air conditioning, but now human beings in modern society can be said to be completely inseparable from air conditioning. Summer is also the season of high incidence of automobile air conditioning problems, because the temperature in other seasons is not high, and riders don't need air conditioning at all, even if there is something wrong with the air conditioning. Therefore, it creates the illusion that there are many air conditioning failures in summer.

Part of the "problem" of car air conditioning is actually

It's all "no problem"

Turning on the air conditioner in summer is nothing more than a few so-called "fault points": the air conditioner has noise, the air conditioner has odor, the air conditioner does not cool at all, and the air conditioner has poor cooling effect. Regarding the first few faults, it is actually very easy to judge. For example, air conditioning noise problems are basically caused by foreign objects entering the fan duct, which causes the fan blades to make a collision sound when running.

Or the installation position of the fan sinks (shifts), causing the blades to rub against other things on the side of the air duct, then the fan will naturally make noise as soon as it is electrified. To solve this problem, you need to ask the master to help you dismantle and repair it, find the rubbing point, and it will be solved soon.

As for the problem of air conditioning odor, it is relatively simple: it is nothing more than the moldy air duct of the air conditioner, which leads to a musty smell. Generally, the most moldy part is the evaporator. Usually we will go to the repair shop to replace the air conditioning filter (air filter) and then thoroughly clean the moldy evaporator.

"No refrigeration" and "poor refrigeration effect"

They are two different things and should be dealt with separately.

The air conditioner doesn't cool at all. Basically, it is nothing more than that the compressor is broken, or the air conditioning pipeline is leaking, and the refrigerant (snow) is completely leaked, which has no refrigeration effect at all. But what if there is cold air blowing from the car air conditioner, but the cooling effect is not strong?

As we said before, it may be that the evaporator is blocked by dust, the condenser is blocked by dust, or the refrigerant (snow) is partially leaked. Of course, these are common air conditioning failures. Today, the "fault" to be said today may not be a fault at all!

Maybe "poor cooling effect" is not a problem at all!

Start with ECO mode!

Now, in order to protect the environment, there will be an ECO mode for car owners to choose from, and many car owners will use the ECO mode for a long time to save fuel. As for whether the ECO mode can really bring more objective fuel-saving miracle to car owners, we will not say it for the time being, but once the ECO mode is turned on, many car owners will mistakenly think that their air conditioners are broken, which can be said.

Everyone knows that the ECO mode of a car is an energy-saving mode, which can theoretically reduce the fuel consumption after the car is turned on, but what does this have to do with air conditioning? -In fact, with the development of science and technology, today's ECO is no longer a single function (that is, reducing engine fuel consumption by reducing the upshift speed), but will reduce the overall energy consumption of the whole vehicle (not just fuel consumption).

When the "variable displacement compressor" encounters

Unreasonable ecological plan ...

For example, many automobile air-conditioning compressors adopt "variable displacement" compressors, which can be basically understood as "variable frequency air conditioning" at home (although the principle is different, it does not hinder our rough imagination). In the past, there were only two working modes of compressors. Once it is turned on, it will be fully output, and it will stop when the temperature inside the car reaches the set temperature.

The current "variable displacement" compressor can adjust the working state according to the working load and manual adjustment. Once the economy mode is turned on, the operation mode of air conditioning compressor will be switched to "energy saving mode". To make the most popular analogy, suppose that the power of air conditioner is "5 horses", then once ECO is turned on, the air conditioner kilometer will be reduced to "3 horses".

If it is sunny, the owner will feel that the temperature of his car is slow and always feel that "the wind is not cold enough". At this time, I am anxious to try to ask people everywhere. In fact, the simplest operation is: turn off ECO mode! As long as you turn off the ECO, you can often feel fierce cold air blowing out within 1 minute, and feel that the air conditioner is "full of blood" again.

Congenital problems cannot be fixed,

Just master the correct usage.

Of course, this is also related to the model. After some cars start ECO mode, the air conditioning performance is reduced, but it is not obvious; And some models are very obvious. For example, I recently borrowed GAC Chuanqi GA4 sedan. As long as the ECO is turned on, the cooling effect of the air conditioner is simply … but it is completely acceptable after the ECO is turned on at night, because there is no solar radiation at night, so the power demand for the air conditioner is not so great.

Well, our analysis of the "false failure" of air conditioning caused by ECO mode ends here. If you are in such a predicament, don't rush to look for someone everywhere. Try to close the ECO first. If the problem is solved, there is nothing wrong with your car. If the fault still exists, you need to go to the repair shop to find out the specific reason.
