The headline was launched today, with original content prohibited from moving。
Whether an old driver has been driving for more than a decade or a new driver with a new driver's license, the vast majority of people's perception of car air conditioning has been a fatal error. Everyone defaults: the ac key in the car is the cooler key, press the ac if you want a cold wind in the summer, and the warm wind in the winter must turn off the ac。
It is this seemingly correct common sense error that has led many people to drive for years, the less cooler air conditioners, the less windy, and the high fuel consumption of the car, the more one to two oils per 100 km in the summer, the less reason they can find themselves。
A number of drivers also drive in the summers to drive acs, lower temperatures, maximum wind, and remain heated in the busy half-day car; in the winter windows there are frequent mists and the blowing of the wind is heavier, and there is a security risk of blurring the sight。
Today we are going to give you a complete picture of the real functions of the ac keys, the bottom principles, the correct use of the four seasons. When you're done with this dry product, you'll be able to say goodbye to air conditioners, cooler in the summer, more thoroughly defrost in the winter, and save a lot of fuel for driving。
I. Correcting errors: ac keys are not cooling keys at all
First, the central truth is that it subverts the perception of the vast majority of drivers: the ac key, not the cold wind switch, nor the cooler button, is just the car air-conditioning compressor's start。
Ac is the abbreviation for air regulation in english and has only one central function: to control compressor work or to stop. The compressor is the core component of car air conditioning, which corresponds to the heart of the air conditioner and its main function is to cool + dehumidify and not control the cold and heat of the wind。
Many people don't know where the heat comes from. It's the simplest word。
Cars are cold and warm from very different sources. The cold wind in the summer, which is driven by compressor-driven refrigerant cycles, absorbs heat cooling in the vehicle; the warm wind in the winter, which costs no gas, is the residual heat generated by engine work and is delivered directly into the vehicle。
The cold and heat of the wind is determined by the red and blue temperature of the wheel in the car, while the ac key, which only regulates whether the compressor is working or not, is not directly tied to the wind temperature。
This is the key area of error:
It doesn't mean it's cold
Turning off the ac doesn't mean it's only hot。
When compressors work, they can both assist with cooling and dewetting alone. The vast majority of drivers use only its refrigeration function, completely neglecting the more functional and critical de-wetting function, which is the source of air conditioning difficulties, fuel costs and fog。
A simple summary of true logic:
In summer, cooler + ac, compression mechanism cold, cold wind
In winter, warmer + ac, compressor dehumidifies and drys the warm wind
The ac is closed and the compressor is out of work, with only natural or engine heat in the vehicle and no cooling, dewetting effect。
Ii. Scratching the ac in the summer is the killer of the air conditioner
Summer driving is the most frequent air-conditioning season and the most mishandling time. A lot of drivers' habits are always wrong。
The most common errors are: direct fire in the car, pressing ac keys, closing the window, turning the wind to cool。
This operation is not only particularly slow but also wastes a lot of fuel。
When the car is tanned, the temperature of the enclosed space is far above the external temperature, up to a maximum of 50 and 60 degrees. Just starting the car, the engine's not moving at a steady pace and the compressor is working extremely inefficiently. At this point in time, the overloading of compressors at the ac will not only have minimal cooling effects, but will also increase the engine burden and fuel consumption will surge。
The correct use of air conditioning in the summer, bearing in mind this standard process, has doubled the speed of cooling and saves fuel:
As a first step, no fire, no air conditioning, four windows opened, or skylights opened and ventilation for about a minute. It's the only way to get rid of all the hot and hot, formaldehyde smell in the car. A lot of people ignore this step, and the heat can't get out of the air。
Step two, start the vehicle, start off the outer cycle, wind in the middle, and continue to heat for 30 seconds. The outer cycle can quickly replace high-temperature air in cars and pave the way for subsequent refrigeration。
Step three, close the window, press the ac key to open the compressor, switch to the inner circulation mode, with temperature between 22 and 24 degrees. This temperature is the most energy-efficient and refrigeration-efficient zone for car air conditioning and does not overconsumption。
The fourth step, after the temperature in the vehicle has fallen, is to switch the outer cycle by 10 minutes to ensure that the air in the vehicle is fresh and that the long cycle does not lead to heat and oxygen shortages and dizziness。
There is also a saving detail that many people do not know about: the summer drive, and the whole ac drive saves more than the wind。
Many drivers drive at low speed to turn off air conditioning and open windows to save fuel. The low speed gap is not significant, but when the speed of the car exceeds 60 yards, opening windows can significantly increase wind resistance, which can lead to much more fuel consumption than air conditioning. The most cost-effective option is to open the window and open the air conditioning。
An error was also corrected: many drivers felt that air conditioners were the most expensive to run, whereas the consumption of car air conditioners depended mainly on whether the compressor worked and the size of the wind was small. Winds only control the speed of the wind and do not add too much fuel consumption。
Three, a warm winter. Should i drive an ac? Ninety percent of the drivers are wrong
The winter fog in the windows and the damp and hotness of the car are a problem for all drivers. The majority of people agreed that a warm winter wind had to turn off the ac or pay for the oil or blow the cold wind。
This is only half the story, and many old drivers don't know the true correct use。
First of all, it's clear: winter is just a warmer, no ac, no gas at all. Warm wind is taken from the remaining heat of the engine, the compressor is not involved in the work, it is activated normally and it is warm and saves fuel。
However, when two scenarios are encountered, the ac must be opened, the effect will be doubled and security concerns will be addressed。
The first scenario: rain and snow, high temperatures, front windshields and fast fog in side windows。
Many of the drivers experienced fog in the winter, which only raised the temperature and increased the amount of wind, so that half-day fog could not be blown, the dampness of the blowing vehicle and the blurring of the sight seriously affected the safety of the vehicle。
The reason is simple: mist is formed by wet water condensing on glass inside the car, and the warm wind can only warm and cannot be dehumidized. The moisture is still inside the vehicle and the fog is naturally recurring。
This is when the ac key is opened, the compressor is activated, and the water in the car's air is absorbed in an instant, and it is quickly wet and dry. Combining a warm wind, an outer cycle, a front-runner fog-proof mode, removes the fog completely in 30 seconds and does not repeat the fog, with a clear vision。
The second scenario: rainy and humid days, cold and humid inside the car, glazing beads and slimy body。
The dry, warm and comfortable inside the car does not suppress the heat。
Many are concerned about the cost of operating the ac in winter, when ac works only to dehumidize, is not fully cooled, has a very low load, is almost negligible, and has a very high cost for safety and comfort。
No ac for spring and autumn? It's a waste of power and a car
In the spring and autumn seasons, when the temperature was appropriate, there was no need for cold or warm winds, and many drivers shut down acs and did not turn on compressors for years。
It is also a bad habit to cut short air conditioners ' lifetimes in a very traumatic car。
Automobile air-conditioning compressors, like engines, require regular operation and lubricants. If the compressor does not work for several months, the internal lubricating oil is deposited, the seals dry and aging, and the problem of carden and the seals are prone。
Long periods of idleness, when suddenly opened in the summer, were prone to poor air conditioning cooling, acoustic noise, fluorine leakage, aging of pipes and high maintenance costs。
The correct use of spring and autumn festivals: aacs are opened once a week for three to five minutes each. It is sufficient to operate the compressor, to protect the air-conditioning system, to extend its useful life and to avoid frequent malfunctions。
V. Ac keys for internal and external circulation is the core of air conditioning
It is not enough to use the ac keys alone, and the internal and external cycles are mixed up in error and are still slow, dull and expensive。
Here's the simplest combination of logic, and the new guy can do it。
Internal circulation applies to the scenes: summer cooling, rapid cooling, air quality in cars, urban congestion. The inner cycle is open, the air in the vehicle is closed, the air is not lost, the cooling speed is the fastest and the fuel is the lowest。
The exterior cycle applies to high-speed vehicles, long driving hours, cloud removal in the rain, window ventilation, heat and oxygen in cars. The outer cycle can replace the fresh air, avoid the accumulation of carbon dioxide in the vehicle, and prevent the vehicle from becoming sleepy and dizzy。
The most taboo operation: a full cycle in summer, or an out-of-way cycle。
(b) full out-of-way cycle, continuous ventilation of air conditioning and high loads of air conditioning, increasing the cost of fuel and cooling
The entire cycle, the air is not in circulation, the car is in a state of lack of oxygen, driving is prone to exhaustion and safety hazards。
Six: the ac keys are misused every year
Many drivers are aware of the cost of the air conditioners, but are unaware of the error, and there are many hidden problems。
First, air conditioning filters are fast and dirty. Cold-hot cycle disorders, water and gas build-up, filter cores are prone to mold, dust bacteria are accumulated, air is blown for long periods of time, cars are heavy in smell and families are prone to coughing, allergies and dizziness。
Second, the evaporation box is damp and moldy. The ac has been inoperable for a long period of time, has been unwetted, has left water in the evaporation box, has bred fungus, has smelted after the air conditioner has been shut down, and will smell of acid the next time it is driven。
Third, compressors age early. The three-year compressor is ageing in one year, increasing maintenance costs。
Use of ac keys in the correct manner not only saves fuel, but also keeps air conditioners dry and clean, non-smelling and longer-lived。
Vii. Summary: four seasons of ac-wide access
Finally, a simple set of air conditioners for the rest of their lives will be organized and driven directly。
Summer tan: open windows to heat, then recycle inside ac+
Fogs from winter: warm wind +ac+ circular, fast except in the fog
Spring, autumn and winter seasons: ac minutes per week to maintain compressor failure
High-speed vehicles: turn off windows and turn on air conditioners, more fuel-efficient than opening windows
Routine travel: internal and external cycle interchanges, cool and fuel-efficient
This will make it clear that car air conditioning is not very good, cold, fuely, and never a problem with car quality, but we have been using it wrong for decades. A small ac key, which contains dry goods that many drivers do not know about, is used to save fuel, comfort and safety, is used in the wrong oil-incurred vehicle, and is in constant danger。
