Chen Xin did not answer Qin Lan's question, because this question did not need to be answered by him.

"Uncle and aunt, have they gone back to their hometown? So Ah Xin, how are you going to get them back? Qin Lan put down the gamepad in his hand and put his hand on Chen Xin's shoulder: "If you need my help, Ah Xin, you can say that I will definitely help if I can do it." ”

Qin Lan said that she would help, Chen Xin believed this, but the place she could help was actually very limited, but Chen Xin still thanked her: "Thank you, Ah Lan, I will say something." ”

Seeing that Chen Xin looked unmotivated, Qin Lan did not force Chen Xin to cheer up, but just said to Chen Xin: "If you are in a bad mood, find something to do, the more decadent you are, the more difficult it is to recover." ”

"Really? Then Ah Lan, what do you think I should do? Chen Xin looked at Qin Lan, and at this time he still didn't want to work in his heart: "And you said you want to stay for two days?" I don't have any extra beds and toiletries, so where do you sleep at night? And you didn't bring a change of clothes, what should you do when you take a shower? ”

"Can't you wear yours?" Qin Lan said something casually, but after saying that, she became embarrassed.

In the past, when they were still a couple, Qin Lan did wear Chen Xin's clothes, but now that the two have broken up, it would be too embarrassing to say this again.

In the end, Chen Xin broke the embarrassment, flattened the can of Coke after drinking, stood up and said: "I originally wanted to give myself a day off today, but if you do this, I can't rest." Come and help, I'll dismantle the air conditioner units you brought first. ”

With that, Chen Xin threw away the can in his hand, walked out of the living room, and walked towards the storage room.

Qin Lan watched Chen Xin walk out and hurriedly followed.

The two lifted an air-conditioner out of the storage room and placed it on the workbench.

Looking at the burnt black air conditioner, Qin Lan took the initiative to ask, "Ah Xin, is this still useful?" How to dismantle? ”

"It's not very bad, it should still work, remove the cover first." Chen Xin sat down, reached out and took a screwdriver and handed it to Qin Lan: "Help screw it." ”

As he spoke, he took another driver himself and began to remove the screws on the external unit of the air conditioner.

With Qin Lan's help, the screws on the external unit of the air conditioner were soon removed, allowing Chen Xin to smoothly remove the shell, revealing the inside.

Although it is protected by the shell, the inside does not seem to be very burned, and all parts remain intact, but it is still burned black.

"It looks good, it should still work." Chen Xin bowed slightly, signaling Qin Lan to continue to help remove the screws.

It is often much easier to disassemble things than to install them, even if you don't know how to disassemble and assemble, you can still do it with your hands when you take the screwdriver and screw it.

And if you loosen all the screws, you can naturally remove them.

With Qin Lan's cooperation, Chen Xin quickly disassembled the air conditioner in front of him into a pile of parts.

Chen Xin put these parts on the workbench one by one, looked at the scorched black on the upper layer and frowned a little, so he said to Qin Lan: "Ah Lan, you go and get a basin of water, these things need to be cleaned." ”

These parts are burned black, and even if they are not burned, a layer of black ash on the surface must be cleaned.

Qin Lan nodded, and was about to go to fetch water, but she didn't see the basin: "Ah Xin, where is your basin?" ”

"Basin?" Chen Xin was also stunned for a moment, and then he remembered that he seemed to have not used a basin for many years, so he said to Qin Lan: "Ah Lan, go to the storage room and get a larger plastic box, I don't seem to have a basin." ”

Seeing this, Qin Lan had no choice but to nod and go to the storage room to get the plastic box without saying anything.

Watching Qin Lan enter the storage room, Chen Xin suddenly had an idea, wanting to test the effect of the system's information state concept blurring.

So I opened the system interface, looked at the air conditioner that showed the detachable, and clicked on the disassembly.

A green light flashed in the storage room, and a public dispatch machine sent by Qin Lan today was silently disassembled into parts and appeared on the shelves, but Qin Lan didn't notice it.

Seeing this scene, Chen Xin was immediately relieved, so that he would not be afraid to use the system functions in front of others, and after the overall upgrade of the shelter, he could also consider recruiting others.

Qin Lan didn't notice what Chen Xin had done just now, took out a large plastic box from the storage room, and asked Chen Xin, "Ah Xin, can this work?" Where's your faucet? ”

"The faucet is next to the tank over there, just put the water in." Chen Xin pointed to the water tank embedded in the wall next to the storage room.

pointed out the location of the water tank to Qin Lan, and Chen Xin was also going to go to the storage room to get some parts out, and then make a ground source heat pump.

However, before Chen Xin could stand up, Qin Lan let out a surprised voice: "Ah Xin, are you using hot water?" You can't waste it if you have a heat source, right? ”

Chen Xin felt a little puzzled, stood up and came to Qin Lan's side, and asked suspiciously, "I've always been cold water!" I dug a well to pump groundwater, not hot water! ”

However, when he reached under the faucet and touched the water coming out, he was also surprised: "What's going on?" Why is this water so hot! ”

Surprised, Chen Xin directly pressed his hand on the wall of the water tank, but what he felt was still warm, obviously the water in the water tank was hot water at the moment.

"What's going on? I've been pumping cold water before! Chen Xindun was puzzled.

His tank has always been cold water, initially just ordinary tap water, and then upgraded to pumped groundwater, and the water temperature has always been cold.

Now it suddenly turned into hot water, which really made him feel very puzzled.

While checking the water tank and water supply system with the system function, Chen Xin was also thinking about what changed the temperature of the water in the tank.

Ground source heat pumps? This is obviously impossible, although the ground source heat pump is used for water circulation, but the connected pipe is valve and opened in one direction, and there is no possibility of backfilling.

As for the temperature rising and causing the water temperature to rise, it will not make the tank feel hot.

"Ah Xin, do you use groundwater? Could it be a hot spring? Qin Lan thought of a possibility at this time.

Hearing Qin Lan say this, Chen Xin thought about it and felt that it was possible, but it didn't make sense.

"That's not right, I've been pumping cold water before, and it's impossible for it to get hot all of a sudden!" Chen Xin still felt very strange, he shook his head and said: "If I had found out that there was hot spring water below, I would have no need to engage in a ground source heat pump, just pump hot water directly and use it, there is no need to engage in shallow ground temperature heating." ”
