Doomsday Bunker Upgrade

Chapter 123 Qin Lan's Sweater (810)

But even though that is said, the manufacture of high-power equipment is obviously much more difficult than the manufacture of ordinary equipment.

The power of the compressor itself is a constraint, and the size design of other parts is not designed for high-power equipment. If you want to manufacture a high-power ground source heat pump, unless Chen Xin uses the system to help transform the parts, otherwise Still need real supporting high-power components.

Of course Qin Lan knew this, so she didn't force Chen Xin to make high-power equipment, but just said to him: "Since high-power equipment is not easy to do, Ah Xin, you should build a ground source heat pump according to an external air conditioner. Just make six ground source heat pumps for our SWAT team. As for how to use it, I can just take it back and hand it over to the experts, you don’t have to worry about it.”

"Okay, since you said that, Alan, then do as you said." Chen Xin did not object.

Using the system to help transform parts also needs to spend survival points. Although the cost is not much, why not do it if he can save a little?

With Qin Lan's help, Chen Xin took out a bunch of parts on the shelf from the storage room, and these happened to be the parts of the air conditioner outside unit he dismantled with the system in front of Qin Lan just now.

Of course, the things disassembled by the system do not have a layer of burnt dirt like the manually disassembled parts, and they are clean as if they were new.

Perhaps it was due to the vague concept of the so-called information state. Qin Lan didn't think there was anything wrong with these parts being new. He just assisted him in assembling these parts one by one under the guidance of Chen Xin.

"Axin, can this pipe be so thin, can it work?" Qin Lan asked Chen Xin with a copper pipe. The copper pipe was only the thickness of a finger, and it didn't look like it could effectively transport heat energy.

Chen Xin didn't care about this, not to mention that he could use system upgrades to improve the efficiency of the equipment and improve the diameter of the copper tube. Even the diameter of the copper tube itself is no problem.

However, he still explained to Qin Lan: "Don't worry, there is no problem with this thickness. The air conditioner uses such thick pipes. Isn't it also possible to achieve high-efficiency cooling in summer?"

"Is the cooling and heating energy the same?" Although she knew that the ground source heat pump works the same as the air conditioner, she still doesn't think the two sets of equipment are the same.

He took the copper pipe from Qin Lan's hand with a smile and connected it to the already assembled equipment. Chen Xin smiled and said, "Why is it different? Isn't it all about heat transfer? And the ground source heat pump's The thermal efficiency is twice that of an air conditioner, and you have seen the heating efficiency of my unit, so don’t worry.”

Qin Lan turned to look at the ground source heat pump installed here by Chen Xin, hesitated for a while, then nodded affirmatively, unzipped his jacket and took off his jacket: "Axin, if you don't tell me, I won't. I think you're still a little hot."

"Who told you to wear such a thick coat indoors?" Chen Xin glanced at the jacket Qin Lan took off, and sure enough, it was thicker.

Qin Lan stretched out, and her impressive figure was wrapped in the thick gray sweater on her body, which made Chen Xin look away in embarrassment: "Is this the sweater I gave you? "

"Yeah, Ah Xin, you bought it for me with the first monthly fee. It should be the first birthday present you gave me, right?" Qin Lan glanced at the sweater on her body and smiled.

"It's been so many years in a blink of an eye, but I didn't expect you to still be wearing it." Chen Xin couldn't help shaking his head, with some emotion.

At that time, he had just quit his original job and planned to become a full-time online writer. Although his parents were very opposed to this decision, Qin Lan spared no effort to support him.

At that time, Chen Xin had a falling out with his parents and moved out of the house. He originally planned to rent a house by himself, but Qin Lan asked him to move directly to her.

It is also with the support of Qin Lan that Chen Xin was able to persevere and become an online writer.

So after he earned his first manuscript fee after becoming a full-time online writer, he bought this sweater for Qin Lan as her birthday present at that time.

Qin Lan likes this sweater very much and has always cherished it, which is also a testimony of their love.

It's just a pity that the two did not get together in the end, but chose to break up.

"Yeah, it's been so many years in the blink of an eye." Qin Lan couldn't help but feel a little emotional, and even said a little narrowly: "I still remember, Ah Xin, you liked that I only wore this sweater! Why did you like to do that at that time? what?"

Regarding this question, Chen Xin turned his face in embarrassment, rubbed his nose and said, "Because you were in good shape at that time, Alan!"

"I said that I seem to be out of shape now." Hearing Chen Xin's answer, Qin Lan showed a smile on his face.

However, she did not continue the topic, but continued to assemble the ground source heat pump with Chen Xin.

With Qin Lan's help, the assembly of this ground source heat pump went very smoothly, much faster than when Chen Xin assembled the first one.

It's just that the parts used in this ground source heat pump equipment come from ordinary household air conditioners, while the first ground source heat pump parts assembled by Chen Xin came from the household central air conditioners. There are also some differences in the size of the equipment that comes out.

"Axin, are you ready?" Qin Lan looked at what Chen Xin had assembled and confirmed to him.

Chen Xin nodded, stretched his waist and stood up: "The assembly is complete, but it still needs to be debugged and checked to see if there is any problem."

"Oh, then leave it alone, don't worry about debugging." Qin Lan also stood up and wiped his hands with a rag.

After being busy for a long time, she couldn't help but feel a little hungry, so she asked Chen Xin, "Are you hungry, Ah Xin? Why don't you eat first?"

"Alan, are you hungry? Okay, let's eat first." Seeing that Qin Lan said she was really hungry, Chen Xin nodded indifferently: "Go wash your hands first, I'll cook."

After speaking, Chen Xin wiped his hands and planned to go to the storage room to get food, but Qin Lan held him down.

"I'll cook today, Ah Xin, you've been busy all afternoon, and you're tired." After saying that, without waiting for Chen Xin to object, he walked towards his storage room.

Looking at Qin Lan's appearance, Chen Xin raised his eyebrows and looked at her back. He couldn't help but hug his chest and put the second knuckle of his right index finger into his mouth.

This is Chen Xin's habit when he thinks about certain issues. Whenever he can't figure out something, he will do it, which will help his thinking.

Biting his finger, Chen Xin fell into doubt and thinking: "Alan... What the hell are you trying to do..."
