Sincere

High -temperature weather is super long standby

Incidents in the car are not uncommon for people

(Why do you say every year

Every year there are such things that appear

today

Let's talk about it again

High -temperature weather in the car safety precautions

(Do you learn to hear well?

How danger is the closed car?

As the weather is getting hotter

Often due to high temperature, accidents in the car occur

How high is the temperature in the car that is exposed to the sun?

Meteorological staff

I did an experiment of "High temperature in the car" in the summer

High -temperature weather in summer

Under direct sunlight conditions

Use professional meteorological observation temperature table

Compare observation experiments of temperature and temperature in the car

the result shows

The vehicle is parked in an open -air sun

In -car temperature within 40 minutes

You can achieve a relatively maximum value

Temperature difference inside and outside the car

Gradually increase with increased temperature

When the temperature is 33.0 ℃

The maximum temperature difference reaches 45.5 ℃

The temperature in the car actually reached 78.5 ℃

Even the cooler place

The temperature in the car can also rise to 47 ° C within an hour

Even if the window seam is opened

No role

On July 14, a mother in Huai'an, Jiangsu got out of the car to buy things and accidentally fell the car key in the car. The door was locked and could not open. Source/Jiangsu Fire Weibo

It is worth noting

Children cannot adjust their body temperature like adults

Especially children under 3 years old

Locked in a closed carriage for 15 minutes

The brain and kidneys will be damaged

More than half an hour

It may cause children

Dehydration, heat stroke, shock

Even suffocating death

For children under 15 years old

Except for a car accident

The heat stroke in the car has become

Vehicle -related deaths

The second cause of death

A few days ago, in Wuxi, Jiangsu, a young child was locked in a car. He was afraid of crying. Firefighters came to rescue, but parents wanted to wait for the unlocking master to open the door instead of the source of the window.

Smelling at high temperature accelerates

Smell more prone to produce

Formaldehyde boiling point -19.5 ℃, easy to volatilize

It has a irritating effect on human eyes and nose

The air conditioning system in the car

Gear in the instrument board system

POM (polydehyde) material for connecting rods

Bubbles such as seats, carpets, ceiling and other foam

All of its main sources

research shows

The quality concentration of formaldehyde at high temperature

Can reach more than 10 times at normal temperature

In addition to "five benzenedehyde"

There are many organic compounds in the car

Including direct chain alkanes, branches of chain alkane

Pyromone, cyclocity, ester and aldehydes, etc.

Some substances have irritating odors

It's harmful to the human body

also

The items that usually put in the car at will

It is likely to cause explosion in high temperature days

Including lighter, old flower mirror, perfume

Carbonated beverages, cooling spray

Insect -proof spray, sunscreen spray, etc.

Research has shown that

The sunscreen spray exploded in 1 second

High -temperature days, how to cool down in the car quickly?

Hot summer

The car is exposed to the sun

Open the door

A heat wave strikes

In the car

Boiled in all directions

It was just a crime

So what are the ways

Can you quickly cool the vehicle?

01

Natural environment cooling

This is the simplest and most direct solution

If there is an underground garage, it is the best

if there is not

Just try to take the vehicle as much as possible

Passing under the big tree or the cool place

02

Switch door to cool down

Before getting on the car, ensure safety before getting on the car

Repeat the door at least 5 times before the door

Utilize the principle of "pulling the box"

Quickly dispel the harmful gases emitted by the exposure in the car

Cool the seat at the same time

03

Clever driving windows to cool down

About the correct window ventilation method

Recommend the following two

Can quickly achieve the effect of cooling.

Method 1: Open two windows on diagonal

Two windows that open the corner

Equivalent to "through the wind"

Let the air -flowing air form a soft "small whirlwind"

The cooling effect is good

Noise is also very small

Method 2: Close the driver's rear car window

Open the remaining three windows

Ventilate

Not only can we gather a lot of air to the back row

High pressure zone

Accelerate thermal exhaustion

And the wind is very soft

04

Air conditioning cooling

After the vehicle is started

Don't turn on the air conditioner immediately

Open the air conditioner at this time

Not only increase fuel consumption

It will also cause the engine to varying degrees

I suggest you open the window first

Drive for about three minutes

Open the air conditioner again

You can enjoy air -conditioning more economical and quickly

There are also a few tips for the use of air conditioners in the car

first

Open the air conditioner outside the air conditioner

The air volume is open to the maximum

At the same time, open the windows and windows

Doing this is to let the air inside and outside the car convex the flow of air

Excess high temperature gas as soon as possible

Then close the window

Air conditioner switch to the inside loop

Towards the temperature and air volume that you feel comfortable

Outlet

Cold air will sink automatically

Improve cooling efficiency

05

Sunny curtain cooling

After the vehicle stops

Install a sun

Can effectively resist most direct sunlight

Reduce the temperature of the seat and the internal car

There is also a car umbrella

It can also play the same cooling effect

at last

Remind everyone again

Hot weather

Be sure to raise awareness of safety precautions in the car

Avoid high temperature injury incidents occur again
