Courtyard: Start with the technician turning positive

Chapter 107 Lin Yu made and assembled a refrigerator, which shocked the neighbors in the hospital, and the neighbors rushed to buy [Ask for Custom].

“System, I want to check in.”

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

“Successful check-in.”

“Reward [White noodles 50 jin] reward [Rice 20 jin] Reward [Rock sugar 5 jin] Reward [Wheat milk essence 10 bottles] Reward [20 pencils] Reward [1 set of electrical tools] Reward [5 jin of eggs]”

“Reward [Milk 10 pounds] Reward [5 bags of rat poison]”

Another variety of check-in rewards.

Good fellow, this time there is not only food and drink, but also rat poison. Lin Yu had long been accustomed to the system’s rewards.

However, Lin Yu can almost guess the award award of each time eight (9) and not far from ten. In short, every reward is bound to be something to eat and drink.

The system is very human, it cares about him, and he can’t let him starve or die of thirst. However, this time, Lin Yu’s attention stayed on the set of electrician tools.

He was planning to make his own refrigerator this morning, and the system brought him a set of electrician tools. The system is really not ordinary humanization!

Give the system a big thumbs up! Get up, get dressed, and wash up.

As usual, Lin Yu first made breakfast for Xiaobai. As usual, it’s a bowl of milk, a bag of cat food.

Xiao Bai ate with relish.

After that, Lin Yu himself also made a simple but not nutritious breakfast. Canned beef slices of bread and a steaming glass of milk.

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

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

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

The working principle of gas absorption refrigerator, mainly to heat source as power, gas absorption refrigerator often use ammonia as a refrigerant, so that liquid ammonia evaporation conditions can be formed, and it also uses hydrogen as a diffusion agent, using ammonia, water and hydrogen mixed solution to complete the refrigeration work.

The working principle of semiconductor refrigerator is mainly to use semiconductor materials to produce the Peltier effect for work, it uses P-type semiconductors and N-type semiconductors to make galvanics, after direct power, it will produce heat release and heat absorption at its nodes, so as to achieve the purpose of refrigeration.

But relatively speaking, the cost of semiconductor refrigerators is too high, even in the market of later generations, it has not been promoted. In contrast, gas-absorbing refrigerators, with low cost and no noise, have been promoted to the world in the future market. Lin Yu decided to assemble a gas absorption refrigerator.

However, there is a problem, that is, it is necessary to fully assemble the various electronic components of the gas-absorbing refrigerator. Lin Yu rode his bicycle through the streets and alleys, shuttling between major department stores and supply and marketing cooperatives.

After running for most of 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 from plastic.

Although the rubber and plastic industry in this era is not very developed, all kinds of plastic forest feathers can still be obtained. Four times back and forth between the compound and the major department stores.

In the end, Lin Yu got all the electronic components and various materials for assembling the refrigerator. The neighbors were puzzled.

In the past, every weekend, Lin Yu couldn’t even see a shadow.

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

When Lin Yu returned to the compound after returning from the fourth full load, Yan Bugui asked Lin Yu in the front yard: “Lin Yu, what are you busy with?” Why don’t you go fishing in the rivers outside the city? ”

Lin Yu said with a smile: “Just pour some gadgets.” Uncle, why didn’t you go fishing outside the city today? ”

Yan Bugui said with a wry smile: “I let the children ride out on my bicycle, let them exercise their cycling skills, and let them carry me out in the future, isn’t it much easier for me to go out?” ”

“That’s true, too.”

Lin Yu responded and pushed the bicycle into the backyard. In the middle courtyard.

Jia Dongxu was lying on the recliner, looking at the sky in a daze. Jia Zhang sat on a chair next to him, collecting the soles of his shoes. Qin Huairu was doing laundry.

Silly Zhu went out to help cook again.

Yi Zhonghai was listening to the radio and drinking tea in the house.

Lin Yu’s return 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 went again and 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.

Jia Zhang pinched the needle and scratched his hair, adding a little oil roller skating to the tip of the needle so that he could continue to apply the sole.

“Who knows, what else can be tinkered with? Tinkering. ”

Jia Zhangshi said angrily.

Qin Huairu looked at Lin Yu’s back, thinking secretly in his heart.

Qin Huairu felt that Lin Yu must be making something with such a lot of effort.

Just like Lin Yu used to buy wood to make furniture, and buy building materials plate cauldron. This time, I don’t know what Lin Yu will make.

“Stick terrier, go to the backyard and see what Lin Yu is pouring again?”

Jia Zhang said to the stick terrier.

“I’m not going.”

The stick terrier shook his head repeatedly.

Leading their two sisters, they ran outside to play.

“This kid is becoming more and more disobedient.”

Jia Zhang sighed. Backyard.

Lin Yu opened the door. Push your bike into the house.

Unload all the materials from the car.

Then take out the set of electrician tools from the system space.

Looking at this pile of electronic components, there are all kinds 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, coupled with the hands-on ability of the eighth-level fitter skill, is simply not too strong.

It didn’t take long.

Lin Yu assembled the electronic components. Another half hour passed.

A refrigerator is already in its own shape.

Outside the house, there was a little head lying on the window, secretly observing what Lin Yu was tinkering with. The little head looked at it for a while, turned around and ran home, and ran to tell Uncle Yi about Liu Haizhong.

“Dad, go and see, Lin Yu has made a new thing, I don’t know what it’s for, but it’s very peculiar to go up…”

Liu Guangfu ran home and shouted at his father’s bangs.

“What? Lin Yu is building something again? Go, see go. ”

Liu Haizhong put down the radio, took a big stride, and walked out of the house with a big belly. The two came to Lin Yu’s house together.

“Hehe, Lin Yu, what are you building again?”

With a shy smile in his bangs, he came over to ask Lin Yu.

Lin Yu did not raise his head, his hands continued to be busy, and he responded: “Make some gadgets.” ”

“Gadgets? I see that what you made is not a gadget, this is clearly a big gadget. ”

Liu Haizhong smiled and complimented.

Lin Yu didn’t bother to deal with him.

The two came to his house, and it was the night owl who entered the house and came without anything. Lin Yu’s indifference made Liu Haizhong a little angry.

But he still patiently asked Lin Yu: “Lin Yu, can you tell me, what is the use of this thing you made?” I know you’re never going to make something useless. ”

Lin Yu said casually: “It’s not summer, the weather is extremely hot, a lot of food can’t be put at all, I plan to make a container specially used to refrigerate food, let’s call it a refrigerator.” ”

The bangs were taken aback.

Lin Yu’s idea is also too bold, right?

What do you actually handmake to refrigerate food in the summer… Refrigerator! By the way, isn’t Lin Yu a technician in their workshop?

When did he learn the skills of an electrician?

Looking at the electronic components that Lin Yu turned together, his scalp was numb with shock in his bangs. There are no impermeable walls in the compound.

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

This news caused Yan Bugui and Yi Zhonghai to run to the backyard, stand at the door of Lin Yu’s house, and look up.

After the stick terrier heard Liu Guangfu tell him the news, he didn’t play outside with his two sisters, and he also ran to the backyard to see the excitement Under the gaze of many neighbors, Lin Yu screwed the last screw.

Refrigerator making 0.2 assembly completed!! Plug in an outlet and plug in the power supply.

The refrigerator starts working, the refrigerator starts to cool, and the cooling fan starts to spin.

This refrigerator made by Lin Yu is divided into two layers, the upper layer is refrigerated, and the lower layer is frozen. The refrigerator door closed, not long after, opened the refrigerator door, reached in, and felt cold. It really worked.

The neighbors were all stunned.

“Oh my God! Lin Yu actually… I actually made a refrigerator myself. ”

“What’s the use of this thing?”

“I heard that it is specially used in summer, and fresh food can be stored for a long time.”

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

Yan Bugui, the most critical and calculating uncle, simply came forward and asked Lin Yu with a smile if this refrigerator was sold? How much to sell, he wants to buy.

However, before Yan Bugui’s words fell, Yi Zhonghai hurriedly said: “Lin Yu, sell this refrigerator you made to me, I will pay fifty yuan, how about it?” ”

The neighbors were all stunned, and this gadget made by Lin Yu, Uncle Yi actually had to spend fifty yuan to buy it. This thing, it’s really worth fifty dollars?!。
