Doomsday Bunker Upgrade

When Chen Xin and the researchers left the room where the ground source heat pump was installed and came to the canteen of the SWAT team, the heating effect of the ground source heat pump was obviously improved after the renovation. Although the temperature was still cold, the temperature in the room was still There is a more obvious rise.

Before Chen Xin's renovation of the ground source heat pump, the people here felt like they wanted to stick to the heating radiator and bake, but now they have changed from water heating to air heating, these people are just around the heating radiator, and obviously You can feel the comfort exuding from their demeanor.

This is actually easy to understand. Plumbing uses a boiler or heat source to heat water for heating. The temperature is generally around 60~80°C, which is a temperature that can be directly held by hand without feeling very hot.

However, air heating uses a heat source to burn water into high-temperature steam for heating. The temperature is above 100°C, which is a temperature that can scald people.

Although both are heating, the difference in heating efficiency can be said to be worlds apart.

For the heating system, if there is no heat source with sufficient heat energy, there is no way to use the heating method of air heating.

But now, only the SWAT team can enjoy the air heating in the entire city police station shelter. After all, the shelter uses water heating as a whole, and air heating and water heating cannot be operated at the same time, so Chen Xin was renovating and upgrading just now. When the SWAT team was located, the heating system connected to the ground source heat pump was independently transformed into air heating.

If the heating of the entire city police station shelter is to be converted into air heating, it will only be possible after Chen Xin renovates the boiler of the shelter.

For this, Chen Xin is not in a hurry at all, because it is really not troublesome at all, the only thing he has to wait is for the city police station to gather the raw materials for the boiler transformation.

So at this time, Chen Xin's demeanor was much easier compared to when he found Qin Lan and Ding Ning in the cafeteria, with a smile on his face.

"Xiao Ding, Alan!" Chen Xinchong greeted the two of them and walked over to the two of them, while the scientific researcher beside him walked aside with great discernment, without disturbing Chen Xin and his friends.

"Axin! Sister Lan said that you just went to remodel the ground source heat pump. How is the situation now?" Ding Ning was very happy to see Chen Xin's performance. While greeting him enthusiastically, he also asked with concern. .

"The upgrade has been completed, don't you feel that the temperature of the heating has risen now?" Chen Xinchong Ding Ning smiled, explained a sentence, and asked her: "Xiao Ding, have you lived here recently? Long's family is over there. Do you know what's going on now?"

Ding Ning shook his head in embarrassment and explained, "I was on duty here when the blizzard came. I started to go back once, but then I didn't have time to go back. It should have been buried by the blizzard by now."

Speaking of this, the expression on Ding Ning's face was a little embarrassed. When Mo Qingyan handed over the house to her before, she asked her to take care of it. Now that the house was buried by snow, although it was due to the weather, the manpower was unstoppable. But it is also true that it was not taken care of.

Hearing what Ding Ning said, Chen Xin nodded clearly. He obviously expected this situation, so he said to Ding Ning: "Longniang also mentioned to me when I came, so I'll take a look back. It's her home anyway, and even though she's moved to mine now, her family can't just give up like that."

"Well, then, Ah Xin, tell me when you go. If I have time, I will go with me. My things are still there!" Ding Ning said something to Chen Xin, thinking of the things he didn't have time to bring out.

Chen Xin nodded and wrote it down, then glanced at the cafeteria again, and asked Ding Ning and Qin Lan, "Can I get something to eat here? I'm a little hungry, Alan, are you hungry?"

"A little bit, but there are too many people here. Let's eat what we brought." Qin Lan also glanced at the cafeteria and shook his head when he saw the long queue at the dining window of the cafeteria. She and Chen Xin were motivated. There is emergency food in the armor, and there is absolutely no need to crowd with these survivors here.

Chen Xin also nodded in agreement, so he asked Ding Ning, "Xiao Ding, is Alan's room still reserved? Or do you know where we can go to eat easily?"

"Sister Lan's room is still reserved, you can just go there." Ding Ning looked at Chen Xin and Qin Lan with some envy.

In fact, she was already very hungry, especially when she was on duty in the cafeteria, it was easier to feel hungry when she smelled the smell of food.

But the duty lies, no matter how hungry she is, she must stick to her post until she can rest, instead of going to get something to eat just because she is hungry.

Chen Xin and Qin Lan didn't say much after seeing this. After saying goodbye to Ding Ning, they walked out of the cafeteria together.

Seeing Chen Xin and Qin Lan walking out, the researchers on the side immediately posted it again and asked Chen Xin, "Mr. Chen Xin, what are you going to do?"

"I'm going to take a rest and eat something. I came out in a hurry when I came here in the morning, and I've been in a hurry since I came here. I'm a little hungry." Chen Xin replied, looking at the researchers and thinking for a moment Said: "You also go have something to eat, you don't have to follow me all the time."

The researcher hurriedly shook his head and said, "No, no, we already had lunch before we came here. I'd better follow you, Mr. Chen Xin. It will benefit me a lot to see Mr. , very inspiring!"

Chen Xin knew that the vague concept of the information state of the system can instantly instill a lot of knowledge and pictures for those who see the upgrade process. The more knowledge people can get, the more instillation they can get. He nodded, tacitly acknowledging that the other party followed his own affairs.

However, Chen Xin went to restart the power armor that he had parked before. After wearing the power armor and Qin Lan to her previous room, he took off the power armor with Qin Lan, and the two walked into the room together.

The room seemed to be the same as before, but Qin Lan had been away for more than a month, and a thin layer of ash had fallen on the table.

Qin Lan found a rag and wiped the table and chairs, and then he greeted Chen Xin to sit down, but the researchers who followed them did not come in, but looked at the power armors parked by Chen Xin and Qin Lan at the door obsessively. Vice wants to study it.

Chen Xin didn't care about him, just took out the emergency food with Qin Lan from the silo behind the power armor and ate it.
