Chapter 123

However, although it is said that, the manufacturing of high-power equipment is obviously more difficult than that of ordinary equipment.

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

Qin LAN certainly knows this, so she did not force Chen Xin to manufacture high-power equipment, but said to him: "since the high-power equipment is not easy to do, ah Xin, you'd better make a ground source heat pump according to one air conditioner, and make six ground source heat pumps for our special police force. As for how to use it, I'll take it back and give it to the experts. You don't have to worry about it. "

"OK, since you said that, ah LAN, just do what you said." Chen Xin has no objection.

Using the system to help transform parts also needs to cost survival. Although the cost is not much, why not save a little?

With Qin Lan's help, Chen Xin takes out a stack of parts from the storage room, which are just the parts of the external air conditioner he disassembled in front of Qin LAN.

Of course, the things disassembled by the system are not as clean as the parts disassembled by hand.

Perhaps due to the so-called fuzzy concept of information state, Qin LAN didn't feel that there was anything wrong with these parts as new ones. He just assisted him to assemble them one by one under the guidance of Chen Xin.

"Ah Xin, this pipe is so thin, can it work?" Qin LAN takes a copper tube and asks Chen Xin. The copper tube is only finger thick and thin. It doesn't look like it can effectively transport heat energy.

Chen Xin didn't think much of it. He didn't say that he could upgrade the system to improve the efficiency of the equipment and the diameter of the copper tube. Even the diameter of the copper tube itself was no problem.

However, he explained to Qin LAN: "don't worry, there is no problem with the thickness. The air conditioner uses such a thick pipe, can't it achieve high efficiency refrigeration in summer?"

"Is refrigeration the same as heating?" Although she knows that the working principle of GSHP is the same as that of air conditioning, 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 said with a smile, "how can it be different? Isn't it all about the heat? Moreover, the thermal efficiency of ground source heat pump is twice that of air conditioner. You can see the heating efficiency of this one. Don't worry about it. "

Qin LAN turned to look at the ground source heat pump installed here by Chen Xin, hesitated for a moment, then nodded for sure, took the opportunity to open the zipper of his coat, took off his coat: "ah Xin, I don't think you are still a little hot if you don't say it."

"Who asked you to wear such thick clothes indoors?" Chen Xin took a look at the coat Qin LAN took off. It's not surprising that it was thickened.

Qin LAN stretched a stretch, and her considerable figure was wrapped in her thick gray sweater, which made Chen Xin look away awkwardly: "is this the sweater I sent you?"

"Yes, ah Xin, you bought it for me with the first month's contribution fee. It should be the first birthday present you gave me?" Qin LAN took a look at her sweater and laughed.

"It's been so many years in a twinkling of an eye. I didn't expect you to wear it." Chen Xin could not help shaking his head with some emotion.

At that time, he just quit his original job and planned to become a full-time Internet writer. Although his parents opposed 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 also with Qin Lan's support that Chen Xincai has been able to persist and become an online writer.

So after he became a full-time Internet writer and earned the first contribution, he bought this sweater for Qin LAN as her birthday present at that time.

Qin LAN likes this sweater very much and cherishes it all the time, which is also the witness of their love.

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

"Yes, so many years in a flash." Qin LAN can't help but feel some emotion, and even said: "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 at that time? "

For this problem, Chen Xin embarrassed side to face, rubbed his nose just said: "because at that time, you have a good figure ah LAN!"

"It's like I'm out of shape now." Hearing Chen Xin's answer, Qin LAN smiles.

However, she did not continue this 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 is 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 the external unit of ordinary household air conditioner, while the parts of the first ground source heat pump assembled by Chen Xin come from the external unit of household central air conditioner. There is a big power gap between the two, so there is also a gap in the size of the equipment."Ah Xin, are you ready?" Qin LAN looks at what Chen Xin has assembled and confirms it to him.

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

"Oh, let's put it first. Don't worry about debugging." Qin Lan also stood up and wiped her hands with a rag.

Busy for most of the day, she can't help feeling a little hungry, so she asked Chen Xin, "are you hungry, ah Xin? Why don't you eat first? "

"Ah LAN, are you hungry? OK, let's eat first See Qin Lan said she is really hungry, Chen Xin indifferent nodded: "you go to wash your hands, I'll cook."

With that, Chen Xin wiped his hands and planned to go to the storeroom to get food, but Qin LAN held him down.

"I'll cook today, Xin. You've been busy all afternoon, and you're tired." Finish saying, wait for Chen Xin to oppose, then walk toward his storeroom.

Chen Xin looks at Qin LAN like this, some eyebrow picking people look at her back, can't help but hold her chest in both hands and put the second knuckle of her right index finger into her mouth.

This is Chen Xin's habit of thinking about some problems. Whenever he can't figure out something, he will do it, which helps him to think.

Biting his finger, Chen Xin fell into doubt and thought: "a LAN What are you trying to do? reunite with? It's impossible for us... "
