Siheyuan: Starting From The Conversion Of Technicians

"System, I want to sign in.

Today is the weekend, Lin Yu woke up, stretched himself, lay on the bed and started to sign in.

"Sign in successfully."

"Reward [50 catties of white flour]

"Reward [20 catties of rice]"

"Reward [5 catties of rock candy]"

"Reward [10 bottles of malted milk]"

"Reward [20 pencils]"

"Reward [1 set of electrical tools]"

"Reward [5 catties of eggs]"

"Reward [milk 10 catties]"

"Reward [5 bags of rat poison]"

Another sign-in reward of all kinds.

Good guy, this time there is not only food and drink, but also rat poison.

Lin Yu has long been used to the system's rewards.

But Lin Yu can almost guess the awards every time.

In short, every reward must have something to eat and drink.

The system is very humane and cares about him very much. He must not be starved to death or thirsty to death.

However, this time Lin Yu's attention was on the set of electrical tools.

He was planning to make a refrigerator by himself this morning, and the system sent him a set of electrical tools.

The system is really not ordinary humanized!

"Six Seven Seven" gave the system a big thumbs up!

Get up, get dressed, wash up.

As usual, Lin Yu made breakfast for Xiao Bai first.

It is still a bowl of milk and a bag of cat food.

Xiaobai ate with relish.

After finishing the work, Lin Yu made himself a simple but not nutritious breakfast.

Canned beef bread, and a cup of steaming milk.

After eating and drinking, Lin Yu pushed his bicycle out the door.

This morning he is going to buy a lot of electrical components for assembling the refrigerator.

Refrigerators can be divided into two types according to the working principle, one is gas absorption refrigerator, and the other is semiconductor refrigerator.

The working principle of the gas absorption refrigerator is mainly based on the heat source as the power. The gas absorption refrigerator often uses ammonia as the refrigerant, so that the evaporation conditions of liquid ammonia can be formed. At the same time, it also uses hydrogen as the diffusing agent. A mixture of ammonia, water and hydrogen is used to complete the work of refrigeration.

The working principle of the semiconductor refrigerator is mainly to use the Peltier effect produced by semiconductor materials to work. It uses P-type semiconductors and N-type semiconductors to make galvanic couples. The phenomenon of heat release and heat absorption, so as to achieve the purpose of refrigeration.

For them, the cost of semiconductor refrigerators is too high, even in the market of later generations, they have not been able to come.

In comparison, the gas absorption refrigerator has low cost and no noise, and has been promoted all over the world in the future market.

Lin Yu decided to assemble a gas absorption refrigerator.

But there is a problem, that is, it is necessary to get various electronic components of a fully assembled gas absorption refrigerator.

Lin Yu rode a bicycle through the streets and alleys, shuttling between major department stores and supply and marketing cooperatives.

After running for more than half the morning, Lin Yu bought all the electronic components for assembling the refrigerator.

As for the shell of the refrigerator, it can be made and assembled with plastic.

Although the rubber and plastic industry in this era is not very developed, all kinds of plastic feathers can still be obtained.

Shuttle back and forth four times between the compound and major department stores.

In the end, Lin Yu got all the electronic components and various materials to assemble the refrigerator.

The neighbors were very puzzled.

Every weekend in the past, Lin Yu couldn't even see a shadow.

But today and this weekend, why did Lin Yu ride his bicycle back and forth several times, and bought so many things?

When Lin Yu returned from the fourth trip with a full load, he returned to the compound. Yan Bugui asked Lin Yu in the front yard: "Lin Yu, what are you so busy doing? Why don't you go fishing by the river outside the city? "

Lin Yu smiled and said, "Take out some gadgets. Third uncle, why didn't you go fishing outside the city today?"

Yan Bugui smiled wryly and said: "I let the children ride out on my bicycle, let them practice their cycling skills, and let them carry me out in the future, isn't it a lot easier for me?"

"That's true."

Lin Yu responded and followed the bicycle into the backyard.

In the courtyard.

Jia Dongxu was lying on the recliner, staring at the sky in a daze.

Mrs. Jia Zhang was sitting on a chair beside her and was picking up the soles of her shoes.

Qin Huairu is washing clothes.

Silly Zhu went out to help the cook again.

Yi Zhonghai was drinking tea while listening to the radio in his room.

When Lin Yu came back, he immediately attracted everyone's attention.

But Lin Yu didn't even look at them, and pushed the bicycle directly into the backyard.

"Mom, I said that Lin Yu has been going over and over again, what is he messing with?"

Jia Dongxu was lying on the recliner, his body could not move, only his mouth could move, he asked curiously.

Jiazhang held the needle and scratched her hair, and put a little hair roller on the tip of the needle, so that she could continue to suck the sole of the shoe.

"Who knows, what else can I mess with? Just mess around." Jia Zhang said angrily.

Qin Huairu looked at Lin Yu's back, thinking secretly.

Qin Huairu felt that Lin Yu must be making something after spending so much time and effort.

It's just like Lin Yu used to buy wood to make furniture, and buy building materials to make big pots.

Maybe Lin Yu will make something again this time.

"Bang Geng, go to the backyard and see what Lin Yu is messing around with?" Jia Zhang said to Bang Geng.

"I won't go." Stick shook his head repeatedly.

He took his two younger sisters and ran outside to play.

"This child is becoming more and more disobedient." Mrs. Cao Zhang sighed.

backyard.

Lin Yu opened the door of the house.

Push the bike into the house.

Remove all materials from the vehicle.

Then take out the electrician's tool set from the system space.

Looking at this pile of electronic components, there are also a lot of materials.

In an instant, dozens of compositions appeared in Lin Yu's mind.

In the end, Lin Yu chose the simplest and most operable composition, and began to assemble it.

The eighth-level electrician skill, plus the hands-on ability of the eighth-level fitter skill, is simply not too strong.

Not long.

Lin Yu assembled the electronic components.

Another half hour passed.

A refrigerator has already taken shape.

Outside the house, there was a little head lying on the window, secretly observing what Lin Yu was up to.

The little head looked at it for a while, then turned around and ran home, and ran to tell the second uncle Liu Haiwang.

"Dad, go and have a look, Lin Yu has created a new thing, I don't know what it is for, but it looks very strange..."

Liu Guangfu ran home and yelled at his father, Liu Haizhong.

"What? Lin Yu is building something again? Let's go and have a look."

Liu Haizhong put down the radio, took big steps, and walked out of the house with a big belly.

The father and father came to Lin Yu's house together.

"Hey, Lin Yu, what are you building again?"

With a shy smile on his face, Liu Haizhong came over to ask Lin Yu.

Without raising his head, Lin Yu continued to work on his hands, and responded, "Make some gadgets."

"Small thing? I don't think what you made is a small thing, it's clearly a big thing." Liu Haizhong complimented with a smile.

Lin Yu didn't bother to talk to him either.

The two of them came to his house because they were night owls and came in for nothing.

Lin Yu's indifference made Liu Haizhong a little annoyed.

But he still asked Lin Yu patiently: "Lin Yu, can you tell me what is the use of this thing you made? I know that you will never make useless things."

Lin Yu said casually: "It's not summer yet. The weather is so hot that many foods can't be stored at all. I plan to make a special container for refrigerating food. Let's call it a refrigerator."

Liu Haizhong was taken aback.

Isn't Lin Yu's idea too bold?

Actually handmade that what is used to refrigerate food in summer...refrigerator!

By the way, isn't Lin Yu a technician in their workshop?

When did he learn electrical skills?

Looking at the electronic components that Lin Yu assembled together, Liu Haiwang's scalp tingled with shock.

There is no airtight wall in the compound.

Soon, all the neighbors in the compound knew that Lin Yu was making a refrigerator specially used to keep food cold in summer in his own home in the backyard.

The news attracted both Yan Bugui and Yi Zhonghai to run to the backyard and stand at the door of Lin Yu's house, looking up.

After BangJiao heard Liu Guangfu tell him the news, he stopped playing outside with his two younger sisters. He also ran to the backyard to watch the fun.

Under the watchful eyes of many neighbors, Lin Ning screwed on the last screw.

Electricity 0.8 refrigerator production and assembly completed!!

Plug it in and turn on the power.

The refrigerator starts to work, the refrigerator starts to cool, and the cooling fan starts to rotate.

The refrigerator made by Lin Yu is divided into upper and lower layers, the upper layer is for refrigeration, and the lower layer is for freezing.

The refrigerator door was closed. Not long after, I opened the refrigerator door and stretched my hand in, feeling chilly.

It's really done.

The neighbors were all shocked and dumbfounded.

"My God! Lin Yu actually... made a refrigerator by himself.

"What's the use of this thing?"

"I heard that it is specially used in summer. Fresh food can be stored for a long time."

When the neighbors learned of the usefulness of this refrigerator, everyone's eyes could burst into flames when they stared at the refrigerator.

The most stingy and calculating third uncle, Yan Bugui, simply leaned forward and asked Lin Yu with a smile, is this refrigerator for sale? How much does it cost, and he wants to buy it.

However, before Yan Bugui finished speaking, Yi Zhonghai hurriedly said, "Lin Yu, sell me this refrigerator you made. I'll give you fifty yuan. How about it?"

The neighbors were all stunned. Uncle Yi actually paid 50 yuan to buy this gadget made by Lin Yu.

Just this thing, is it really worth five thousand dollars?!.
