But having said that, 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, you still need to really match the high-power parts.

Of course, Qin Lan also 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 make a ground source heat pump according to an air conditioner external unit, and make six ground source heat pumps for our SWAT team." As for how to use it, I'll just take it back and hand it over to the experts, you don't have to bother. ”

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

It also costs survival points to help transform parts with the system, although it doesn't cost much, but why not save a little?

With Qin Lan's help, Chen Xin took out a pile of parts from the storage room that were placed on the shelves, and these happened to be the parts of the air conditioner outdoor unit that he had disassembled with the system in front of Qin Lan just now.

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

Perhaps it was the credit of the so-called vague concept of information state, Qin Lan didn't feel that there was anything wrong with these parts like the new ones, but under Chen Xin's guidance, he assisted him in assembling these parts one by one.

"Ah Xin, this pipe is so thin, can it work?" Qin Lan asked Chen Xin with a copper pipe, which 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 caliber of the copper pipe, even the caliber of the copper pipe 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 a thick pipe, isn't it also able to achieve high-efficiency cooling in summer?" ”

"Is cooling the same as heating?" Although she knew that the ground source heat pump worked the same as the air conditioner, she still didn't think that the two sets of equipment were the same.

With a smile, he took the copper pipe from Qin Lan's hand and connected it to the equipment that had been assembled, Chen Xin smiled: "Why is it different?" Isn't it all about the transport of heat? Moreover, the thermal efficiency of the ground source heat pump is twice that of the air conditioner, and you can see the heating efficiency of my unit, so don't worry. ”

Qin Lan turned his head to look at the ground source heat pump installed by Chen Xin here, hesitated for a moment before nodding affirmatively, took the opportunity to unzip the coat on his body, and took off the coat: "Ah Xin, I don't think you are still a little hot if you don't say it." ”

"Who told you to wear such a thick one indoors?" Chen Xin glanced at the coat that Qin Lan had taken off, and sure enough, it was thickened.

Qin Lan stretched her waist, and her considerable figure was wrapped in the thick gray sweater on her body, which made Chen Xin look away a little embarrassed: "Is this the sweater I gave you?" ”

"Yes, Ah Xin, you bought it for me with the first month's manuscript fee, it should be the first birthday gift 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 wear it." Chen Xin couldn't help but shake his head, a little emotional.

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 fell out with his parents and moved out of the house, he originally planned to rent a house by himself, but Qin Lan directly asked him to move to her.

It is precisely with Qin Lan's support 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 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 me very much at that time, I only wore this sweater!" Why did you like to do that? ”

Regarding this question, Chen Xin turned his face away in embarrassment, rubbed his nose and said, "Because Ah Lan was in good shape at that time!" ”

"It's like I'm not in good shape right now." Hearing Chen Xin's answer, a smile appeared on Qin Lan's face.

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

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

It's just that the parts used in this ground source heat pump equipment come from ordinary household air conditioning units, and the first ground source heat pump parts assembled by Chen Xin come from household central air conditioning units.

"Ah Xin, are you doing a good job?" Qin Lan looked at the things that Chen Xin had assembled and confirmed with him.

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

"Oh, then let's put it first, don't rush to debug." Qin Lan also stood up and wiped her hands with a rag.

After being busy for most of the day, she couldn't help but feel a little hungry, so she asked Chen Xin, "Ah Xin, are you hungry?" Why don't you eat first? ”

"Ah Lan, are you hungry? Okay, let's eat first. Seeing that Qin Lan said that she was indeed hungry, Chen Xin nodded indifferently: "You go wash your hands first, I'll cook." ”

After speaking, Chen Xin wiped his hands and was about to go to the pantry to get food, but Qin Lan held him down.

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

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

This is Chen Xin's habit when thinking about certain issues, and whenever he can't figure out something, he will do it, which helps him think.

Biting his fingers, Chen Xin fell into doubts and thoughts: "Ah Lan...... What the hell are you trying to do? Compound? We're no longer possible......"
