Cold chain for 20 years

Chapter 82 Dawn
"Different! Dawn succeeded!"

Luan Pingxin's tone was full of excitement that Hu Shutong had never heard before, and even a little trembling.

Hearing these five words, not to mention Luan Pingxin, even Hu Shutong's cheeks became numb!
Don't look at these five words, there is endless darkness behind it and the hard work in the darkness.

"Dawn" is a screw refrigeration compressor. Our country jointly designed and produced the first oil-injected screw refrigeration compressor in 1976, but there is a huge gap compared with foreign countries. It has been improving for more than 20 years.

Compared with the oldest piston refrigeration compressor, the screw compressor has a simple structure, fewer wearing parts, high volumetric efficiency, low exhaust temperature and can realize stepless adjustment of cooling capacity.

In recent years, foreign brands have built factories in China one after another, using Chinese labor to control and occupy the compressor market on Chinese soil, firmly grasping the core technology, forming a situation where more than a dozen major foreign brands compete.

And dawn is our national brand!

This is the beginning of the competitiveness of domestic compressors. No matter how fierce the competition environment is in the future, we will have a seat!
Lixiao is not perfect yet, but the gap has been made up in quality.Lixiao adopts a new tooth type line, and the efficiency is 10% higher than that of the standard type line; the oil separation efficiency of the new oil separator reaches 99.998%, which is comparable to the first-class products in the United States and abroad; in terms of internal volume ratio, Lixiao can only allow customers to choose three of the multiple choice questions. Instead of a slide valve, a manual internal volume ratio adjustable device has been developed.

For more practical control functions, the intelligent microcomputer control system is used to adjust the cooling capacity, avoiding excessive manual intervention, and achieving mechatronics.

What is even more admirable is its birth process. These complex craftsmanship are indispensable, but as long as one of them fails to take shape, dawn will still be eternal night.

And this is exactly what Luan Pingxin suffers from. She and her team are working hard every day, and she is in the laboratory every day, but she often cannot see the dawn, nor can she predict when the day will come. Such persistence is not easy. .

To give a particularly popular example, why do people like to eat sunflower seeds, because every time they eat one, they will get a sense of taste satisfaction, which will motivate them to eat the next one.But many people in the front line of scientific research, many of them will not even be inspired by the results in their entire lives, but they will still do it.

"Unlike, I really want to see you right now."

Luan Pingxin was a little choked up, and Hu Shutong also had tears in his eyes. Although they were separated by thousands of miles, Luan Pingxin's voice and appearance seemed to be right in front of him at this moment.This strong and stubborn girl went back to a small corner to talk to herself on the phone, and she didn't have to hide her crying or laughing.

This is a memorable moment in Luan Pingxin's life. From the internship to the present, after four years of worshiping the cold, he finally sharpened his sword.

When the dawn came out, Hu Shutong's inner unbearableness became more intense. Unlike Luan Pingxin, when a plan is made, there is a feedback on the plan, and when a task is completed, the burden can be unloaded. These days, the inner suffering is silently unbearable. language.

At this moment, Hu Shutong suddenly heard the sound of the music box, and the crisp blue Danube sounded. Suddenly, Hu Shutong's heart followed him to the distance.He tucked his phone over his shoulder and started to pack it up.

This plan and that plan are all thrown away, and this problem and that problem cannot be compared with what is in front of us.

"I'm sorry Ping Xin, I've been too busy recently, but if there are fewer things to do, I will definitely go to you."

"It's not unusual at all, so I asked you to give me this at that time."

"Then I'll hang up first, and I'll call you tomorrow morning."

"Mass production will start at Lixiao at the end of this month, and the testing process has exhausted me to the point of exhaustion. Go ahead, I should take a good rest."

"I have to get up early tomorrow, and I won't be able to stop once I get lazy."

"I have to be lazy for a few days! Hang up!"

Luan Pingxin lives in an old-fashioned building not far from the group. Four five-storey small buildings surround a small square in the middle. Charming lilacs bloom in the flower beds, and stone slabs are still strong after many years of stepping on the feet.

After the phone rang, Luan Pingxin came to the balcony. Her eyes widened first, and then she pursed her lips into a sweet smile.

He saw Hu Shutong standing by the flower bed, and he was blown in front of him like a night wind dreaming of his heart.Regardless of washing and dressing up, she ran downstairs.

This is a scene that Hu Shutong will never forget all his life. Luan Pingxin is like a princess who ran out of the garden. When she came to her, she tilted her head on purpose. I am relieved.

"Who said it was busy?"

"Busy to get tickets."

Luan Pingxin turned her eyes sideways, her eyes shining brightly, "To show how touched I am, this girl will spare no effort to cook you breakfast."

"A thousand miles away, one meal is not enough."

Their eyes met, Luan Pingxin raised his eyes, and Hu Shutong focused, as if time and space were frozen for a moment.

After embracing, the two joined hands and walked upstairs.

When I walked into the room, I saw that the table was full of documents and materials, and it was too late to organize them. Once they were organized, I didn’t know how to find them. It was exactly the same as the scene in my own dormitory now.

Luan Pingxin didn't care about these at all, and soon heard the sound of sizzle from the kitchen.

Other people's trophies and certificates are all placed in a good place to show them. Luan Pingxin is good, standing beside the TV like a bunch of dwarves.There are no decorative paintings on the walls, only equipment drawings.

"Student Hu, don't be dazed, clear the table and prepare to eat!"

The things on this table didn't dare to move around, Hu Shutong carefully moved all kinds of materials, but one of the poster-like contents caught Hu Shutong's attention.

I saw that it said——

"Madrid Refrigeration Exhibition".
