Doomsday Bunker Upgrade Chapter 122: Qin Lan’s sweater (8/10)

"I can upgrade the shelter ()" to find the latest chapter!

However, that 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 restriction, and the size design of other parts is not designed for high-power equipment. If you want to make a high-power ground source heat pump, unless Chen Xin uses the system to help modify the parts , Otherwise, real matching high-power parts are still needed.

Qin Lan knows this too, so she didn’t force Chen Xin to make high-power equipment, but said to him: “Since high-power equipment is not easy to make, Axin, you should build a ground based on an external air conditioner. Source heat pumps. Just give our SWAT team six ground source heat pumps. As for how to use them, I will take them back and give them to the experts. You don’t have to worry about it."

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

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

With the help of Qin Lan, Chen Xin took out a pile of parts on the shelf from the storage room, and these happened to be the parts of the external air conditioner that he had disassembled 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 parts that are disassembled manually, and they are clean as if they were new.

Perhaps due to the so-called vague concept of information state, Qin Lan didn't feel that these parts were the same as new ones, but only assisted him to assemble these parts one by one under Chen Xin's guidance.

"Axin, can this pipe be so thin, can it be useful?" Qin Lan asked Chen Xin with a copper tube. This copper tube is only the thickness of a finger and does not seem to be able to effectively transport heat. look.

Chen Xin didn't care about this. Not to mention that he could use system upgrades to improve equipment efficiency and improve the diameter of the copper pipe. Even the diameter of the copper pipe itself is not a problem.

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

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

With a smile, he took the copper tube from Qin Lan and connected it to the assembled equipment. Chen Xin smiled and said: "Why is it different? Isn't it all about heat transfer? The thermal efficiency of the source heat pump is twice that of the air conditioner, and you have seen the heating efficiency of mine, so don’t worry.”

Qin Lan turned to look at the ground-source heat pump installed here by Chen Xin. After hesitating for a while, he nodded with certainty, unzipped the zipper on his coat and took off the coat: "Axin, don't you tell me? I don’t think you are a bit hot."

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

Qin Lan stretched her waist, her impressive figure wrapped in the thick gray sweater on her body was not tempted, and Chen Xin turned away from her gaze a little embarrassingly: "This is the one I gave you. sweater?"

"Yes, Axin, you bought me the first month's manuscript fee. It should be your first birthday gift, right?" Qin Lan glanced at the sweater on her body and smiled.

"It's been so many years in a blink of an eye. I didn't expect you to be wearing it." Chen Xin couldn't help shook his head, feeling a little.

At that time, he had just quit his original job and planned to become a full-time online writer. Although his parents opposed 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 directly let him move 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 draft 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. This is also a testimony to the love between the two.

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

"Yes, 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 at that time! Why did you do it then? Do you like doing that?"

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

"It seems like I'm out of shape now." Hearing Chen Xin's answer, Qin Lan showed a smile on his face.

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

With the help of Qin Lan~IndoMTL.com~ The assembly of this ground source heat pump is very smooth, much faster than when Chen Xin assembled the first one.

It’s just that the parts used in this ground-source heat pump equipment are derived from ordinary household air conditioners, and the first ground-source heat pump parts assembled by Chen Xin are derived from household central air conditioners. The power gap between the two is somewhat large. , So the size of the equipment made is also somewhat different.

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

Chen Xin nodded, stretched and stood up: "The assembly is complete, but it needs to be debugged. Check to see if there are any problems."

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

After busying for most of the day, she couldn't help feeling a little hungry, so she asked Chen Xin: "Ah Xin, are you hungry? Shall we eat first?"

"Alan, are you hungry? Okay, let's eat first." Seeing Qin Lan said that she was really hungry, Chen Xin nodded indifferently: "You should 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.

"Let me cook today, Ah Xin, you have been busy all afternoon, and you are also tired." After finishing speaking, before Chen Xin objected, he walked towards his storage room.

Chen Xin looked at Qin Lan, looked at her back with raised eyebrows, and couldn't help but put his hands on his chest, bending 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.

Bite his finger, Chen Xin fell into doubts and thinking: "Alan...what are you doing? Reunion? It's impossible for us..."
