After the noon class, Song Chu got in touch with the friend introduced by Gu's father.

The other party sent a construction team over, and Song Chu took them to the back mountain, and then handed over the design drawings he had drawn to the captain.

The captain has always been engaged in architecture, and when he got the design drawings and looked at them carefully, although he had never built such a thing, his company could build it.

After the communication between them was confirmed, the price was negotiated, and a contract was signed for both copies, and with the consent of the school, work can start tomorrow.

When he started working, Song Chu would take time to go over every day to take a look, and if there was a problem, he would immediately point it out.

In the second week, when Song Chu returned to school, he brought a simple small refrigeration fan.

It would take time to make an air conditioner, and Gu Yue was afraid that Song Chu would be too hot in the school accommodation or experiment, so it took a week to make a small cooling fan.

Nowadays, the fan rotates and uses the surrounding wind to blow out to cool down, but the weather is too hot and the wind is also hot, so the effect of the electric fan is not very good.

Gu Yue added a new type of refrigeration to the fan, and the wind blowing out was about the same as the air conditioner adjusting to about 18 degrees of cold air, and the power was small and would not consume much electricity.

If Song Chu wants to use it in the dormitory or laboratory, he has to say hello to the principal first, after all, it requires electricity.

So she went to the principal's office with a fan in her arms.

Principal Zhu and Vice Principal Ding were talking about something, and they were surprised when they saw Song Chu knocking on the door.

He immediately said with a smile on his face: "Xiao Song is here, come in." ”

Song Chu walked in and sat down, "Principal Zhu, I came here because I wanted to discuss something with you." ”

Principal Zhu smiled and asked, "What's the matter?" ”

Song Chu put the desktop fan on the table, "It's too hot now, I've studied a small refrigeration fan, so I want to use it in the dormitory and laboratory, so I want to ask you if it's okay." ”

Principal Zhu and the others naturally knew who she was targeting, and they all looked at the fan on the table.

"Refrigeration fans? Does it mean it's different from a regular fan? ”

Song Chu nodded: "It's different, the wind it blows out is refrigerated by a layer, so it will be very cool." ”

Principal Zhu and the others instantly showed curiosity, "Can you try it?" ”

Song Chu smiled: "Of course you can." ”

Principal Zhu personally turned on the electric fan, and soon the rotation of the fan gradually blew out a cool breeze, making the stuffy office much more comfortable.

"This wind is so cool, it's really different from ordinary fans." Principal Zhu came over and couldn't put it down, looking left and right.

There is also an electric fan in his office, but the wind that blows out is hot, but it is slightly better than not blowing at all.

But this electric fan is different, it blows out completely cold air, which is particularly comfortable.

"Xiao Song, does this refrigeration fan consume electricity?" He asked.

Song Chu replied truthfully: "My object deliberately changed the power to a smaller one, and it consumes about one kilowatt-hour of electricity in about five hours. ”

"That's not a lot of electricity."

Now there are air conditioners purchased from abroad in China, Principal Zhu saw it once some time ago, and experienced it, it is indeed very cool, but the power consumption is very scary, almost one kilowatt-hour of electricity.

In addition, the air conditioning itself is very expensive, and their school really can't afford it.

But the refrigeration fan brought by Song Chu made them feel moved, and it was still necessary to put one in the laboratory.

Now that the weather is hot, the professors in the laboratory are all old, and they have been doing experiments all the time, and one person fainted from heat stroke two days ago.

They were worried about this, but they didn't expect Song Chu to send the solution to the door.

"Xiao Song, do you sell this air conditioning fan over there?" Although Principal Zhu knew that the Gu family's grandson would definitely not be short of money, he still couldn't help asking.

"A few days ago, our professor fainted from heat stroke during an experiment, and our school couldn't afford to buy a laboratory for air conditioning from abroad, and the electricity bill was very expensive."

"So if you sell it, our school wants to buy a few of these cooling fans and put them in each laboratory for everyone to use." He added with a sigh.

As for their office, he didn't dare to think about it, for fear that it would be too expensive.

Song Chu hadn't thought about selling this thing before, but when he heard their words, he suddenly had an idea.

"I'm going to ask him about this first, can I get back to you later?"

Principal Zhu smiled and nodded: "Okay, then I'll trouble you." ”

"You can use this refrigeration fan, whether it is in the dormitory or in the laboratory, the electricity bill is out of our school, after all, I said before that I would give you a separate laboratory, and now you don't want it, this is even the benefit of work compensation."

He heard many people say that Song Chu is a lucky star, but he didn't think so before, but now he thinks that she may be true.

The things they have been worrying about these days, she can just come across to help solve them.

Song Chu didn't refuse, she originally wanted to say that she would pay the electricity bill, "Okay, thank you Principal Zhu." ”

Out of the office, she didn't go back to the dormitory, but went to a more remote corner of the campus, and then entered the space lab.

Now there is no surveillance, and no one will notice that she has disappeared into thin air.

At this time, Gu Yue had just returned home after sending Song Chu and found that Song Chu had entered the space laboratory, so he guessed that something might be wrong with her, so he also quickly went in.

"Is something wrong?" Gu Yue asked.

Song Chu gestured to the electric fan he was holding with his eyes, "Our school wants to buy this." ”

Gu Yue was stunned for a moment, and quickly reacted to what it meant, "I only made a few units, if I want to buy them, then I will work overtime and bring someone to make a few units?" ”

If someone from the Agricultural University wants to buy it, he certainly doesn't have the time and energy to help build a few units, after all, he still has a lot of new projects to do.

And he didn't provide it at BGI, and only sent one to the offices of several teachers.

But if it was his own Song Xiaochu who wanted to, then he would work hard and work overtime.

Song Chu put down the electric fan and reached out to hold his arm, "You don't need to work overtime, you are so tired, it's not me who is distressed." ”

Gu Xueshen is so fond of her, how can she be willing to let him work so hard.

Gu Yue's heart warmed, and he chuckled: "For you, I'm willing to work hard." ”

"You don't have to work overtime with me, but you came to me to talk about this, you should still want to provide fans for Agricultural University, do you have a better idea?" He still knows his object better.

Song Chu nodded: "I think, if you don't let my fourth brother do it, what do you think?" ”

"Although he has invested in the club's project, he will not mainly do this in the future, I have always wanted my fourth brother to do that piece, and now because of this, I think it is good to make household appliances."

"Your technology is shared, and my fourth brother will open a factory to realize it, which will not only lead foreign countries in technology, but also benefit everyone." She added.
