Doomsday Bunker Upgrade

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

But even though it is said, the manufacturing of high-power equipment is obviously much more difficult than the manufacturing 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 Still need real matching high-power parts.

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

"Okay, since Alan, you said that, just do what you said." Chen Xin did not object.

It also costs survival points to use the system to help transform parts. Although it doesn't cost much, why not 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 just happened to be the parts of the external unit of the air conditioner that he had disassembled with the system in front of Qin Lan.

Of course, there is no burnt dirt on the disassembled parts of the system, and it is clean as if it 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 the new ones, but only assisted him to assemble these parts one by one under the guidance of Chen Xin.

"Axin, this pipe is so thin, can it work?" Qin Lan asked Chen Xin holding a copper pipe. This copper pipe is only the thickness of a finger, and it doesn't seem to be able to effectively transport heat.

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

However, he 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 knowing 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? And the ground source heat pump The thermal efficiency is twice that of an air conditioner. You can see 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. After hesitating for a while, she nodded with certainty, unzipped the zipper on her coat and took off the coat: "Axin, if you don't tell me, I will not I think you are still a bit hot."

"Who told you to wear such a thick one indoors?" Chen Xin glanced at Qin Lan's coat that was taken off. As expected, it was thick.

Qin Lan stretched out, and her impressive figure was wrapped in the thick gray sweater on her body. Instead, she was not tempted. Chen Xin turned her gaze away a little embarrassingly: "Is this the sweater I gave you? "

"Yes, Axin, you bought me with the first month's contribution fee. It should be your first birthday present, 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 but 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 quarrel 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 was also with Qin Lan's support that Chen Xin was able to persevere and become an online writer.

So after he made his first contribution 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 of their love.

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 a blink of an eye." Qin Lan couldn't help feeling a little, and even said narrowly: "I still remember Axin, you liked me wearing only this sweater at the time! Why did you like to do it then? what?"

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

"It seems that I am not in shape now." Qin Lan smiled on Chen Xin's answer.

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~www.ltnovel.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, while 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 that comes out is also somewhat different.

"Axin, are you done now?" Qin Lan confirmed to him looking at the things that Chen Xin had assembled.

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

"Oh, let's just let it go for now, don't worry about debugging." Qin Lan also stood up and wiped her 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 she was indeed 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, 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 thinking about certain issues. Whenever he can't figure out something, he will do it, which helps him think.

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