Sheng Yuqiu made a big mistake.
She was originally a liberal arts student, how could she think about these things?
Of course, based on some life experience extracted from her daily life, it is natural that she uses quilts to keep warm, and using quilts will heat up ice cubes.
Su He explained with a smile: "The function of the quilt is actually to lock in some heat. From a physical point of view, cold air is also temperature. The reason why the quilt can keep warm is that it can isolate most of the air from the human body. contact, thus reducing the heat exchange between the body and the cold outside air.
The quilt isolates the internal temperature from the outside world, so when the temperature inside the quilt is higher than the outside temperature, the quilt plays the role of insulation (so people feel warmer in the quilt); when the temperature inside the quilt is lower than When the outside temperature is high, the quilt plays a role in keeping cold.
Therefore, quilts are actually for thermal insulation, not for heating. "
Su He's explanation made Sheng Yuqiu understand that he had made a big mistake before.
She was a little shy, but Su He didn't say any more.
He is a straight man, but he is not a straight man.
Su He smiled and said: "Come and try it. This small electric fan is a small electric fan I made myself using a motor and the principle of electromagnetic conversion. Because I planned to get some ice water in the box, I blew it out. It’s the cold. So I don’t plan to use too much horsepower. Just give it a try and see if it works.”
Obviously, that's a very comfortable thing.
Su He immediately agreed to come up. Anyway, I was very used to doing that kind of handwork, and I quickly made several handmade air conditioners.
Why is my life so miserable?
Yes, the customers were all small industrial factories, and air conditioners for civilian use were not available for the time being.
That kind of carpentry, compared to outside craftsmanship, is all very rough.
"The existence of the ozone layer is due to its ineffective absorption and isolation of ultraviolet rays from the sun. Excessive ultraviolet radiation can also induce various eye diseases, such as cataracts, corneal tumors, etc. So the ozone layer is very important."
In the future, when the old man knows about the matter.
Put the ice cubes back out of the water and put the lid down.
In my free time, I chatted with Sheng Wenyang.
Just as he was talking, the big pumpkin actually got up.
Sheng Yuqiu looked back at the old man and said to himself, because he knew where his precious grandson had gone, he would say that about you.
Because I don’t have any trouble, I need to manually replace the ice cubes and ice water outside every day.
"Oh, this is tin foil. Just like a quilt, it is insulated. The box inside is nailed up with wooden boards. It is inevitable that there will be some gaps. Although the cotton outside the quilt is tight, there is no such problem. So you Get some tin foil and take a step back to keep it warm. Go get some ice cubes and ice water. Try it and see if the horsepower is enough."
Just as he was about to turn on the fan, Big Pumpkin asked curiously: "Brother, what is that he did?"
The morning passed quickly in the process of making that kind of handmade air conditioner.
If there is not enough saltpeter, the saltpeter will be extracted again. Those ice cubes are difficult to obtain.
It seems that Big Pumpkin is still very satisfied with his future sister-in-law?
Mr. Sheng looked at Mou Shuhui and felt that he had seen something strange.
Mou Shu shook his head slightly, and without thinking, went to get some ice cubes and ice water.
That would be like digging a hole with your own hands and then jumping out of it.
Mou Shuhui said proudly: "What your friend made by hand is an air conditioner in this tolerant sense."
Just when Sheng Yuqiu was not worried, it was time to know what to say.
The two people's eyebrows moved and they had an in-depth exchange.
Mou Shu cannot see his parents at any time.
There is no manual air conditioner like that, it's just the same.
Even if you add a basin of ice, you will be woken up by the cold in the middle of the night.
Sheng Wenyang reluctantly put the ice cubes out of the ice box and got some ice water to put back.
You took out the saltpeter and made some ice cubes according to your memory.
Sheng Wenyang came back and relieved me.
It would not appear until 1986.
The atmosphere was not strange. Mr. Sheng thought, "Are they hiding something from you?"
Sheng Yuqiu glanced at Su He and was glad that he was not a straight man like the third brother, nor was he a woman who knew about style like the fifth brother.
It's just you, Big Pumpkin. Su Mei and Sheng Wenyang were disgusted and felt very comfortable.
In addition, saltpeter is also common, so few people know about it, and even fewer people use it.
After a while, Sheng Wenyang's elders also came back.
It's just that I don't think there's anything weird about it.
Sheng Yuqiu pursed her lips: "The saltpeter used to make ice locks in the cold air. The principle is very complicated. People who have read books and understand physics can easily make it. It's very complicated."
If it doesn’t work, naturally we’ll do a few less and have one per person.
Mou Shu simply explained together.
Thomas Midgley invented chlorofluorocarbon gas in 1928 and named it Freon.
It means that I have no materials, and even if I don’t have materials, my handiwork can’t produce such a crude handmade air conditioner.
I just stopped there.
Sheng Yuqiu said: "That kind of knowledge, I know it in the future. But have you thought about it in that aspect?"
That kind of heating agent is harmful to humans, but it is not harmful to the ozone layer. "
But it can also cause the indoor humidity to be too high, which is also quite comfortable.
"Bag? Seventh brother isn't here yet, he's already here. Come here, you haven't even gotten an air conditioner back."
I wanted to cry, but at that time, it was too early.
Fortunately, Sheng Wenyang brought back seven air conditioners. After squeezing them together, it was still enough.
"Bad, bad, bad, nothing."
"It's bad, he is the worst to grandpa."
"Let's try the simple air conditioner you made by hand. See how it goes. If it doesn't work, make less."
Su He also urged me, but I was not eager to meet the elders of the Sheng family.
There is a place to explain that principle.
Xiang Yazi and Yucheng Yazi also walked back from inside. It seemed that they were looking for the big pumpkin.
So Su He's workmanship was extremely bad.
The technique of making ice with saltpeter also shocked Sheng Wenqiao.
Although he hasn’t been seen by Bage Mou Shuhui yet.
It can be seen that it is because it is given to Sheng Wenyang's family.
Sheng Wenyang hummed: "Everyone, after learning knowledge, can flexibly apply it in life to improve the quality of your life."
You bad cabbage, don’t let the pig give you away.
He mentioned it a little bit, but Su He said less.
I was just planning to have fun, and Su He also firmly believed that it was a relationship that was preceded by marriage, not a hooliganism.
Mou Shuhui is still preparing to trick Mou Shu into seeing his family.
It was used for good, but it also caused some problems.
At this time, it was really embarrassing.
Although my memory and understanding abilities have improved slightly, when I study, the knowledge will actively fly out of my head.
After we took back a few boxes, Sheng Wenqiao said: "What kind of air conditioner is that? Is it an electric fan? Is it the same fan? Isn't it a little bigger? It's still a corner, can there be no wind? Yes. Put the fan closer so there is no wind, right?"
If so, just using a fan would be cool enough.
If I had known earlier, I would have gone to Bishui City and pulled back the time bomb.
If you keep chasing yourself to explain, you will understand everything but only roughly understand the truth.
But although Sheng Yuqiu was worried, she dared not say anything.
After dinner, Mou Shu and Sheng Wenyang took a quick walk home together.
Although in my heart, environmental protection is very important.
This triumphant look almost made Sheng Yuqiu break her guard.
Usually it's after class, but Big Pumpkin doesn't wake up until he's an hour and a half old.
Is that envy, jealousy, and hatred?
What friend, girlfriend.
I walked back and forth outside my home without any relief.
"So, Brother Ba is talking about very complicated things. Can anyone who has studied physics do it? Brother Ba, just solve it yourself."
That time, there were so few of them.
This is something that other developed countries in the world have experienced during their development process.
Mr. Sheng's eyes were very keen and he discovered some clues.
"The air conditioner is not made by Willis Carrier of Eagle Sauce. I am the engineer and inventor of Eagle Sauce. It was invented in 1902. By 1906, I applied for a patent..."
If Su He was revealed, would the Sheng family be in danger of an earthquake?
When the time comes, the old man will also let me go.
It’s about whether I take responsibility, but whether Sheng Wenyang’s bad image is ready to be broken.
Unexpectedly, the eldest sister didn't react at all and kept praising that friend.
The old man's most cherished pearl was stared at by others.
Sheng Wenyang said proudly: "How's it going? Is the air conditioner your friend made wrong?"
Sheng Yuqiu looked at Sheng Wenyang without any resentment: "You helped him hide the matter and carried the thunder. When this day breaks out, the old man will still worry about it. In the end, did you have any share in the air conditioner?"
"What are you talking about?" Sheng Wenqiao said with a frown.
Su He helped move the handmade air conditioner to the door of Sheng's house and was seen by neighbors.
But those words didn't sound sour?
Immediately, Big Pumpkin, you all clamored to Su He to ask me to make one and use that one tonight.
Sheng Wenqiao also understood that his starling seemed to be such a rigid person.
Su He even made a few less and planned to give eight or seven to Sheng Wenyang for you to take back.
Sheng Yuqiu only felt that the boy was Zhongliu.
"Then outside, he also made a quilt? Then what is that layer outside?"
"air conditioner?"
Fortunately, the motor I prepared is enough. If so, there is really no way to appease no one in the house that time.
But today's country is so poor that it has to trade the environment for economic development.
Sheng Yuqiu was not surprised: "Aren't air conditioners sold in our country?"
Sheng Yuqiu is a very humble person, and he has always been strict, and many people will say such things.
You need to tell people outside the family about Su He first, and then find time for Su He to visit his family.
At this stage, there is no air conditioning in the country.
You are so shameless and shameless, just like the air conditioner did it yourself.
While Su He was making that kind of handicraft, while taking a break, he took out the books he received in the afternoon and read them.
"The original air conditioners and refrigerators used non-toxic gases such as ammonia and methyl chloride. Such gases would cause major accidents before they leaked.
Sheng Yuqiu knew in her heart that that friend was probably not Su He.
The temperature inside is still very low. Although there is not a tree outside the yard, the tree crown covers much of the sun.
But Sheng Wenyang said, I am also a bad person.
Do I have any brothers or sisters in the future?
"He dares to say that you are done with him." "I really want to tell the old man now that no one is going to steal my cabbage."
Why did you recruit that person back?
The old man is still angry and has a stomachache?
That kind of hand-made air conditioner is not as convenient as the air conditioner in the previous life.
Sheng Wenyang said: "You are knowledgeable. Show him how powerful the air conditioner is."
It is said that boys are introverted, but the ancients were really trying to bully you.
Sheng Yuqiu opened her mouth because she knew what to say.
"What is air conditioning?"
"Air conditioning."
The two communicated loudly. Did Sheng Wenqiao see it? He asked without any surprise: "Bago, if he can do it, he can make one for you. There is no such thing as making ice with saltpeter. How can Bago be with him in the future?" What do you think? If there is no air conditioning, it would be bad to get an ice basin at night."
Sheng Yuqiu didn't bother to say it was true, but she dared to say it now because she was afraid that her eldest sister would miss her.
In the end, it was just causing trouble for myself.
You asked Su He to put the things at the door, and then urged Su He to go back first.
Now, it's not yet a year.
"What's that look in his eyes?"
Well, the main thing is that the universality of knowledge is not as developed as in the previous life.
But the small area was already so cold, but before retreating, the manual air conditioner blew out the hot air outside the box and blew it outside the room.
Anyone who misses it is bad.
He actually concealed something so important.
Sheng Wenyang hummed a few words and said: "If Bage knew, how could he make one at such a young age? If he had made it earlier, he would have honored grandpa earlier. We still have to wait for your friends to make it. You go and ask for a few Come back and give your grandparents a good relief from the heat."
Su He was also very satisfied with that phenomenon.
Miss Su Mei and brother-in-law Qian Rui also came over and looked at the box behind them curiously, knowing what Su He was doing.
When Sheng Yuqiu came back from work, she actually saw her eldest sister outside the house.
When the hot air blew out, driving away the cold outside the house, the Sheng family felt a rare refreshing feeling.
Then if my eldest sister knew that I had leaked, she wouldn't have a bad look on me.
In the evening, Su He cooked a small table of dishes and invited Sheng Wenyang to eat.
I just want to say it out, but my eldest sister will let me go when the time comes.
Mr. Sheng looked at his grandson angrily and said, "What is he doing walking around outside? It's very annoying."
At that moment, Sheng Wenyang reacted and quickly denied: "Are you there? Are you talking about that air conditioner? Grandpa, does he think you are bad to him? I specially asked him to bring one back and let him use it in the evening. One night. Basically, I just need to replace the ice cubes, but at least it can keep me warm for one night."
After all, saltpeter is not toxic at all.
Before, it was not necessary to close the cover, insert the latch, and turn on the switch.
Sheng Yuqiu was not surprised: "How about making saltpeter ice? In ancient times, in some small households, except for storing ice cubes in the winter, no one knew that method. But in recent years, more people have used it."
"Ah, it's so comfortable."
When they reached the alley near Mou Shuhui's house, Lu Yuan had been waiting there for a long time because he was driving.
"Moreover, breaking the ozone layer will lead to global warming. In the future world, the annual average temperature will decrease year by year. Summers will become colder."
"Sister Yuqiu." Big Pumpkin ran over, hugged one of Mou Shuhui's calves, and grabbed your hand.
What does that do?
Really, I know what to say.
That big girl is going crazy for fun, will she be back in the evening?
