Chapter 0165: Medal!!

“My refrigerant, which is an ordinary refrigerant, has the same effect.”

“If anything, it’s my refrigerant, which is more environmentally friendly.”

“Eco-friendly?”

Hearing Lin Weidong’s explanation, Professor Li and Professor Liu were a little puzzled.

Aren’t today’s refrigerants environmentally friendly?

Seeing their puzzled expressions, Lin Weidong explained: “The current refrigerants are basically Freon 12. ”

“But according to my guess, Freon 12 will cause damage to the ozone layer.”

“Because after the release of chlorofluorocarbon gas, it slowly rises to the top of the ozone layer in the atmosphere.”

“When CFCs float in the air, they begin to decompose due to the ultraviolet rays in sunlight, releasing chlorine atoms.”

“These chlorine atoms are extremely reactive and like to combine with other substances. So when it encounters ozone, it begins to produce chemical changes. ”

“Ozone is forced to break down into an oxygen atom and an oxygen molecule, and the chlorine atom is combined with the oxygen atom.”

“But when other oxygen atoms encounter this chlorine oxidation molecule, they snatch the oxygen atom back to form an oxygen molecule, and the chlorine atom that recovers into a single can destroy other ozone.”

Hearing Lin Weidong’s explanation, Professor Li and Professor Liu’s faces became extremely serious.

Even if they are not experts in this area, they understand the importance of the ozone layer.

“If so, aren’t we slowly destroying the environment in which we live.”

Professor Li said with fear.

“So to speak.”

Lin Weidong nodded.

“Then the refrigerant you studied will not cause damage to the ozone layer?”

“Of course not, or would I have to make it special?”

“But we can’t make the refrigerant you mentioned, after all, we know very little about it.”

Professor Liu said with a frown.

“So I helped us contact a chemistry laboratory through the second elder.”

“I see.”

Professor Li nodded cautiously: “I will report this matter.” ”

“If what you say is true, you’re a great deal.”

After speaking, Professor Li was not resting and directly proposed to leave.

“By the way, this is the reward given to you above.”

Before leaving, Professor Li took out a small box with a medal inside.

“Because of the special circumstances, the above chose not to be public.”

Professor Lee explained.

“Understandable!”

Lin Weidong nodded and carefully accepted the medal.

The current situation in the country is not very peaceful.

However, this medal, after the wind rises, will become another life-saving talisman for him.

After Professor Li and Professor Liu left, Lin Weidong saw that the things on their transport truck were left.

It was Professor Li who asked the people of the security department to move in front of Lin Weidong.

After Lin Weidong opened it, he saw a set of drones.

At this time, the drone is still in a folded state, only more than two meters long.

However, after the arms and blades are deployed, it will reach four or five meters.

This is a small UAV whose function is to detect and provide fire support at short and medium distances.

Professor Li and the whole set of drones they sent were very complete, even the machine gun components and grenade components were sent together.

There were also two boxes of grenades next to it, which made Lin Weidong’s eyes a little hot, and he wanted to control it and try it.

But after thinking about it, let’s wait first, Elder Huang and the big leader, it is estimated that they are also waiting to see the drone.

If he knew that Lin Weidong didn’t wait for them to play first, I was afraid that he could mumble to him all day.

So Lin Weidong called Elder Huang and the big leader respectively, and then went to the parking lot.

Since his car arrived, he hadn’t tried it himself.

“Director, where are you going?”

Seeing Lin Weidong coming to the parking lot, the driver of the transport team who was always on standby in the lounge next to him quickly walked out and asked.

“It’s okay, you guys go back, I’ll just walk around the neighborhood and try the car.”

Lin Weidong waved his hand and said.

“This… Director or I’ll go with you. ”

The leader of the transport team said.

“Okay then.”

Lin Weidong nodded and did not let him follow, and they were probably not at ease.

Lin Weidong started the car slowly, and at first gave Lin Weidong a good feeling, after all, the road repair in the institute was still very flat.

It’s that the acceleration is very slow, and the car vibrates greatly.

But after driving out of the institute, it will not work, it is very bumpy, and the shock absorption ability is very poor.

“What do you think of this car?”

After returning from the test drive, Lin Weidong asked.

“It feels good.”

Zhao Pan’er nodded.

The captain of the transport team also hurriedly said: “That’s right, this is definitely a good car. ”

“The cars in the rolling mill are not as good as this car.”

Listening to their answers, Lin Weidong also knew that he had asked in vain…

They have not taken the car of the later life, how can they have any evaluation.

“Let’s go, let’s go back.”

Lin Weidong already had a general upgrade plan in his heart.

The most important thing to upgrade is naturally the engine.

The engine is the heart of the whole car, and then the bearings, which are equivalent to the joints that connect the trunk of the car.

Some small functions in later generations, such as listening to the radio, playing music and so on, can now be left unadded.

If it is too troublesome, it may not be possible to do it with the current technology.

But air conditioning function, this must have.

Otherwise, it’s okay in winter, and the big summer can die of heat in this iron box.

Of course, the shock absorption function must be well upgraded.

Riding in a car is not just a comfortable one.

After having an idea, Lin Weidong took action directly.

One by one, the drawings appeared in front of Zhao Paner.

In this regard, Zhao Paner also felt Lin Weidong’s drawing speed and pride again.

People who don’t understand the situation think that Lin Weidong just sits in the office every day, takes so much money, and keeps being promoted.

But Zhao Pan’er has seen the hard work that Lin Weidong and others have not seen in the past few days.

The drawings that were densely painted and ordinary people had a headache when they saw it, appeared one by one under Lin Weidong’s pen.

How much knowledge does it take to save to draw so many and responsible drawings.

“Off work!”

Hearing the ringing, Lin Weidong stretched out his hand and waved in front of the stunned Zhao Pan’er.

“Oh, let’s pick up Xixi 1.41!”

Zhao Pan’er quickly came back to her senses.

The next day, before Lin Weidong arrived at the research institute, Huang Lao and the big leader had already arrived at the rolling mill.

However, he did not go in, but sat directly in the car and waited.

Seeing Lin Weidong coming, he quickly got out of the car.

“Wei Dong, you can come, where is the drone, take me to see.”

Elder Huang said impatiently.

“Right at the research institute!”

Lin Weidong smiled and led the way in front.

And when he walked to the door of the institute, looking at the security department standing guard next to him, one person and one 81 bar, Huang Lao was a little envious.

“It’s really yours, my guards haven’t even changed into new equipment yet, but your security section here has changed first.”

“That is, I, the designer, can’t be shabby to the people under my hand.”

Lin Weidong said with a smile.

When Huang Lao heard this, he laughed and scolded a few times…
