Chapter 120

Chen Xin didn't answer Qin Lan's question because he didn't need to answer it.

"Uncle and aunt, have they gone back to their hometown? How are you going to get them back, ah Xin? " Qin LAN put down the game handle in her hand and put her hand on Chen Xin's shoulder: "if you need my help, ah Xin, just say that I can do it for you."

Qin Lan said that she would help, which Chen Xin believed, but the place she could help was very limited, but Chen Xin still said to her, "thanks a LAN, I will say something."

Looking at Chen Xinyi's listless appearance, Qin LAN doesn't force Chen Xinzhen to do it. She just says to Chen Xin, "if you're in a bad mood, find something to do. The more decadent you are, the more difficult it is to recover."

"Yes? What do you think I should do, Alan Chen Xin looked at Qin LAN. At this time, he still didn't want to work: "and you said you would stay for two days? I don't have any extra bed and toiletries. Where do you sleep at night? And you didn't bring your laundry. What do you do when you take a bath? "

"Can't you wear yours?" Qin Lan said a word, but then she was embarrassed.

When they were lovers before, Qin LAN did wear Chen Xin's clothes, but now that they have separated, it would be too embarrassing to say that again.

In the end, Chen Xin broke the embarrassment, flattened the coke can, stood up and said, "I wanted to take a day off today, but as a result, I can't rest. Come and help. I'll take down the outside air conditioners you brought

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

Qin LAN watched Chen Xin go out, and quickly followed him.

Two people will be an air conditioner outside the unit from the storage room carried out, put on the workbench.

Looking at the scorched air conditioner, Qin LAN asked: "Xin, is this still useful? How do you want to dismantle it? "

"It's not very hot. It should still work. Take off the cover first." Chen Xin sat down, reached for a screwdriver and handed it to Qin LAN: "help screw it."

With that, he himself took another screwdriver 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 quickly removed, allowing Chen Xin to remove the shell smoothly, revealing the appearance inside.

Although it is protected by the outer shell, it seems that the interior is not badly burned, and all kinds of parts remain intact, but they are still burned black.

"It looks good. Everything should work." Chen Xin nodded slightly, indicating Qin LAN to continue to help remove the screw.

It's easier to disassemble than to install things. Even if you don't know how to disassemble and assemble, you can still do it with your hands when you screw with a screwdriver.

If you loosen all the screws, you will be able to remove what you can.

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

Chen Xin put these parts on the worktable one by one. Looking at the blackened layer above, he frowned a little, so he said to Qin LAN, "ah LAN, you need to get a basin of water. These things need to be cleaned."

These parts are black, even if not burned out, the surface of a layer of black ash is also necessary to clean.

Qin LAN nodded, ready to pick up the water, but did not see the basin: "Xin, where are you basin?"

"Basin?" Chen Xin was stunned for a moment. Then he remembered that he had not used the basin for many years, so he said to Qin LAN, "ah LAN, go to the storage room and get a bigger plastic box. I don't seem to have a basin."

Seeing this, Qin LAN had to nod her head and didn't say anything more. She went to the storeroom to get the plastic box.

Looking at Qin LAN into the storage room, Chen Xin suddenly moved an idea, want to test the information state of the system, the concept of fuzzy exactly what effect.

So I opened the system interface, looked at the display of the detachable external unit of the air conditioner, and click disassembly.

The green light flashed in the storage room. A public dispatching machine sent by Qin LAN today was quietly decomposed into parts and appeared on the shelf, but Qin LAN didn't feel it.

Seeing this, Chen Xin immediately felt relieved that he would not be afraid to use the system functions in front of others. Moreover, after the overall upgrade of the refuge, he could also consider recruiting other people.

Qin LAN didn't find out what Chen Xin had done just now. She took out a large plastic box from the storage room and asked Chen Xin, "ah Xin, can this work? Where's your tap? "

"The tap is next to the water tank over there. Just let it go." Chen Xin pointed to the water tank embedded in the wall next to the storage room.

Qin LAN pointed out the location of the water tank, Chen Xin is also ready to take some parts out of the storage room, and then make a ground source heat pump.

However, before Chen Xin got up, Qin LAN made a surprised voice: "ah Xin, are you using hot water? You can't waste heat like that, can you? "

Chen Xin felt puzzled. He stood up and came to Qin LAN. He asked: "I've always been cold water! I drilled a well to pump groundwater, not hot water! "However, when he reached under the tap and felt the water flowing out, he was also surprised: "what's the matter? Why is the water so hot! "

Surprised, Chen Xin presses his hand directly on the wall of the water tank. As a result, he still feels warm. Obviously, the water in the water tank is hot at the moment.

"What's the matter? I've been pumping cold water before! " Chen Xin was puzzled.

The water stored in his tank has always been cold water. At first, it was just ordinary tap water. Later, after upgrading, it became groundwater extracted. The water temperature has always been cold.

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

While checking the water tank and water supply system with system functions, Chen Xin is also thinking about what changes the water temperature 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 one-way opening, so there is no possibility of backflow.

As for the rise of temperature, it will not make the water tank feel hot.

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

Hearing what Qin Lan said, Chen Xin thinks it's possible, but it doesn't make sense.

"That's not right. I've been pumping cold water before. It can't get hot suddenly!" Chen Xin still felt very strange. He shook his head and said, "if I had found that there was hot spring water below, I would have no need to build a ground source heat pump. I would have pumped hot water directly. There was no need to build a shallow geothermal heating system."
