Chapter 0163: How the Refrigerator Works, The Light Mapping Machine Manufacturing Completed!!
“Don’t dream.”
Liu Lan said angrily.
“Is it possible for us people to enter a place like the institute casually?”
“I heard Director Li say, don’t look at Sister Ye, they are also recruited normally, but on the day of entry, the three generations of ancestors have been clearly investigated.”
“It’s also terrible.”
It was also the first time that MCA and others heard the news, but they did not have the slightest doubt about the accuracy of the news.
After all, the relationship between Liu Lan and Deputy Director Li, they also know a little.
“Isn’t it three generations of ancestors, but I…”
Halfway through, He Yuzhu was suddenly stunned.
He can’t casually say what kind of third-generation farmer he is now, because he was implicated by a deaf old lady before, after being caught in, he directly checked all his family background.
Thinking about this, He Yuzhu despondently found a place to sit.
“You want to be lazy again, don’t you see that we are still busy?”
The fat man always supervises him, the former ‘master’.
At the same time, Lin Weidong was also perfecting the refrigerator drawings in front of him.
In fact, the working principle of the refrigerator is really not very complicated.
The refrigerator consists of a box, a refrigeration system, a control system and accessories.
In the refrigeration system, it is mainly composed of four parts: compressor, condenser, evaporator and capillary throttle, which is a closed circulation system of its own.
The evaporator is installed above the inside of the refrigerator, and the other components 010 are installed on the back of the refrigerator.
The system is filled with refrigerant.
The refrigerant is vaporized into gas by a low-pressure liquid in the evaporator, absorbing the heat in the refrigerator and reducing the temperature in the box.
The refrigerant that becomes gaseous is sucked in by the compressor, compressed into high temperature and high pressure gas by the compressor’s work, and then discharged into the condenser.
In the condenser, the refrigerant continuously releases heat into the surrounding space and gradually condenses into a liquid.
These high-pressure liquids must flow through the capillary tube, throttle and reduce the pressure to slowly flow into the evaporator, maintain continuous vaporization in the evaporator, absorb heat and cool.
In this way, the refrigerator uses electric energy to do work, with the help of the refrigerant state change, the heat around the evaporator in the box is moved to the condenser after the box to be released, and so on and so on to achieve the purpose of refrigeration.
So the difficulty of production is not very large, most of the materials are now in the research institute.
The only thing missing is refrigerant.
Lin Weidong remembers that foreign countries discovered Freon 12 as a refrigerant around the thirties.
Later, several refrigerants such as Freon 22 were found.
But these refrigerants will cause damage to the ozone layer.
Finally, R410A refrigerant that is more environmentally friendly, will not destroy the ozone layer, and works more efficiently has been produced.
R410A refrigerant is a refrigerant mixture consisting of HFC-like substances.
A mixture of R32 (difluoromethane) and R125 (pentafluoroethane).
Especially the second one, it seems that I haven’t found it yet.
Lin Weidong knows the production method, but this thing, he is a chemical thing.
That is, it does not belong to physics, let alone machinery.
Lin Weidong’s mechanical research institute has no production conditions at all.
It seems that after that, we will try to see if we can contact some chemistry laboratories through the big leaders or Professor Li.
At this time, there was two knocks on the office door.
“I’ll go to the shutter.”
Zhao Paner, who was panicking, hurriedly went to open the door, and it was Meng Yuxin outside.
“Forester, all the parts of the light plotter, we have already made them all,” Meng Yuyun reported.
“That’s wonderful.”
Lin Weidong stood up directly.
It took a week for them to finish all the materials for the light plotter.
“Take me quickly.”
“Good!”
Because the institute has just been completed, the parts are still all in the rolling mill
After Lin Weidong arrived at the rolling mill, in an empty room, he saw various parts neatly arranged, as well as various tools needed for assembly.
However, because assembling the light mapping machine is too complicated.
So it took two and a half days to assemble three photomappers.
This speed was achieved with the help of all the engineers and technicians of the institute.
After Lin Weidong’s side was assembled, Director Yang and Deputy Director Li ran over like sharks that smelled blood.
“Wei Dong, this is the light mapping machine you designed yourself?”
Looking at the brand new machine in front of him, Director Yang kept smiling.
“I’ll keep one in the rolling mill.”
Seeing Director Yang like this, Lin Weidong knew what he wanted to say.
If it weren’t for this, Lin Weidong wouldn’t have directly assembled three of them.
“Haha, that’s great.”
Yang Changchang laughed.
But then he looked at the remaining two light mappers: “Wei Dong, what are you going to do with these two.” ”
“The institute needs one.”
“That’s as it should be, but what about the last one?”
“I’m going to send it to my teacher.”
Lin Weidong said angrily.
“It should be, it should be!”
Director Yang said with a sneering smile.
After returning to the institute, Lin Weidong contacted Professor Li.
Drawings of light plotters, they should be in great demand.
Soon, after the phone was transferred, before Lin Weidong could speak, Professor Li’s excited voice came from the other side: “Weidong, I just wanted to contact you to tell you good news.” ”
“Good news? Could it be that the drone made it? ”
“That’s right, we’ve managed to make a sample, and the effect is much better than we expected, it’s really strong.”
“That’s really good news.”
However, Lin Weidong did not show too much excitement, because he knew that this was an inevitable thing.
After Professor Li was excited, he also remembered that Lin Weidong was looking for him, and quickly asked: “Weidong, what is the matter with you this time.” ”
“It’s not a big deal, just I made some improvements to the light plotter, if you need it, I can give you the drawings.”
“Light Machine… What the? Light Plotter! ”
Professor Li reacted sharply.
“Wei Dong, you said you improved the light mapper?”
“That’s right!”
Lin Weidong nodded.
“What is the result of the improvement, how much is the efficiency compared to before, and how much the accuracy has improved.”
Professor Li asked in a series of questions.
“Specific data, you better come and test it yourself, I have already made samples here.”
“Wei Dong, such a big news, you didn’t tell me earlier.”
“You wait, I’ll go to your institute.”
Lin Weidong looked out the window, although it was still very bright, it was almost time to leave work.
Hurriedly said: “Professor Li doesn’t need to be so anxious, or come back tomorrow morning.” ”
“Anyway, the machine is placed here, and it won’t run.”
“Okay then!”
Professor Li had to nod.
“You kid is also true, I don’t know when to choose a better time to tell me.”
“I’m afraid it’s hard to fall asleep this night, no, I have to tell Lao Liu to go, he doesn’t want to sleep tonight.”
After speaking, Professor Li hung up the phone.
Hearing the last sentence, Lin Weidong shook his head funny.
They’re really friends…
