Doomsday Bunker Upgrade

Chapter 120 Hot groundwater (510)

Chen Xin did not answer Qin Lan's question, because he did not need to answer this question.

"Aunt and uncle, have they gone back to their hometown? How are you going to bring them back, Ah Xin?" 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 Say whatever I can, and I will definitely help."

Qin Lan said that she would help, and Chen Xin believed it, but the areas she could help were actually very limited, but Chen Xin still thanked her: "Thank you Alan, I will tell you something."

Seeing Chen Xin's lack of energy, Qin Lan did not force Chen Xin to cheer up, but said to Chen Xin, "If you are in a bad mood, just find something to do. The more decadent you are, the harder it is to recover."

"Really? What do you think I should do, Alan?" Chen Xin looked at Qin Lan, at this moment he still didn't want to work: "And you said you wanted to stay for two days? I don't have any extra. Bed and toiletries, where do you sleep at night? And you didn't bring laundry and change clothes, what should you do when you take a shower?"

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

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

In the end, Chen Xin broke the embarrassment, squashed the finished Coke can, stood up and said, "I wanted to give myself a day off today, but I can't rest because of you. Come and help. , I'll dismantle the air conditioners you brought."

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

Qin Lan watched Chen Xin go out, and hurriedly followed.

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

Looking at the charred outside unit of the air conditioner, Qin Lan took the initiative to ask, "Axin, is this still useful? How do I dismantle it?"

"It didn't burn very badly, and it should still be usable. Take off the cover first." Chen Xin sat down, reached out and took a screwdriver and handed it to Qin Lan: "Help me tighten the screws."

Having said that, he also took another screwdriver and started to remove the screws on the outside unit of the air conditioner.

With Qin Lan's help, the screws on the air conditioner's outer unit were quickly removed, allowing Chen Xin to remove the outer casing and reveal the inside.

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

"It looks good, everything should still work." Chen Xin nodded slightly and motioned Qin Lan to continue to help remove the screws.

It is often easier to disassemble things than to install things. Even if you don't know how to disassemble and assemble, you can still do it by hand with a screwdriver.

After loosening all the screws, the ones that can be dismantled can be dismantled naturally.

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

Chen Xin put these parts on the workbench one by one, frowning a little at the burnt blackness on the upper layer, so he said to Qin Lan, "Alan, go get a basin of water, these things need to be cleaned."

These parts are all burnt black, even if they are not burnt out, the layer of black ash on the surface must be cleaned.

Qin Lan nodded and was about to pick up the water, but he didn't see the basin: "Axin, where is your basin?"

"Basin?" Chen Xin was also stunned for a moment, then he remembered that he hadn't used a basin for many years, so he said to Qin Lan: "Alan, go to the storage room and get a bigger plastic box, I'm here. There doesn't seem to be a pot."

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 a thought, wanting to test the effect of the vagueness of the system's concept of information state.

So I opened the system interface, looked at the display of the detachable external air conditioner, and clicked on the dismantling.

A green light flashed in the storage room, and a public tuner that Qin Lan sent today was silently broken down into parts and appeared on the shelf, but Qin Lan didn't notice it.

Seeing this scene, Chen Xin immediately felt relieved, so that he was not 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 realize what Chen Xin had done just now. He took out a large plastic box from the storage room and asked Chen Xin, "A Xin, can this be used? Where is your faucet?"

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

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

However, before Chen Xin stood up, Qin Lan made a surprised voice: "A Xin, are you using hot water? You can't waste it like this 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 have always been cold water! I dug a well and pumped groundwater, not hot water!"

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

Surprised, Chen Xin pressed his hand directly 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 all the time!" Chen Xin was puzzled.

The water in his water tank has always been cold water. At first, it was just ordinary tap water. Later, after the upgrade, it became groundwater. 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 water tank.

Ground source heat pump? This is obviously impossible. Although the ground source heat pump uses water circulation, the connected pipes have valves and are opened in one direction, and there is no possibility of backflow.

As for the water temperature rising when the temperature rises, it does not make the water tank feel hot.

"Ah Xin, the groundwater you use? 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 thought it was possible, but it didn't make sense.

"That's not right, I've been pumping cold water all the time, it's impossible to suddenly get hot!" Chen Xin still felt very strange, he shook his head and said: "If I had found out that it was hot spring water earlier, I didn't need it at all. If you have a ground source heat pump, you can directly pump hot water for use, and there is absolutely no need to engage in shallow ground heating."
