Chapter 291: eat

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, after the renovation, the heating effect of the ground source heat pump has been obviously improved. Although the temperature is still cold, the temperature in the room is still There has been a more pronounced rise.
Before Chen Xin transformed the ground source heat pump, the people here felt like they couldn’t wait to stick them on the radiator fins, but now that they’ve switched from plumbing to air heating, these people just surround the radiator fins, and it’s obvious You can feel comfort in their expressions.
This is actually easy to understand. Plumbing is heated by heating water through a boiler or a heat source. The temperature is generally around 60~80°C. It is a temperature that can be held directly 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 burn people.
Although both are heating, the difference in heating efficiency can be said to be vastly different.
For the heating system, if there is no heat source with sufficient heat energy, there is no way to use air heating.
However, for the entire city’s police station’s shelter, only the SWAT team can enjoy air heating. After all, the entire shelter uses plumbing heating. Air heating and water heating cannot be operated at the same time, so Chen Xin was upgrading and upgrading. At the time, the heating system connected to the ground source heat pump in the area where the SWAT team was located was independently transformed into air heating.
If the heating of the entire city police station's refuge is to be converted into air heating, it will only be possible after Chen Xin has modified the refuge's boiler.
For this, Chen Xin was not in a hurry, because it was really not troublesome at all. The only thing he had to wait was for the city police station to gather the raw materials for the boiler transformation.
Therefore, Chen Xin's expression is a lot more relaxed than before, and when he finds Qin Lan and Ding Ning in the cafeteria, his faces are also smiling.
"Xiao Ding, Alan!" Chen Xinchong said hello to the two and walked to the two of them, while the scientific researcher beside him walked aside with great eyesight and did not disturb 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 behaving. While greeting him enthusiastically, she also asked with concern. .
"The upgrade has been completed, don't you feel that the temperature of the heating is rising now?" Chen Xinchong Ding Ning smiled, and then asked her after an explanation: "Did you live here recently? Xiaoding? Do you know what is going on now?"
Regarding this question, Ding Ning shook his head a little embarrassed and explained: "I was on duty here when the blizzard came, and I started to go back once, but then there was no time to go back. There should have been buried by the blizzard."
Speaking of this, the expression on Ding Ning’s face is a bit embarrassing. When Mo Qingyan handed over the house to her before, she asked her to take care of it. Now the house is buried by snow. Although it is due to the weather, manpower is unstoppable. But it can be said that it has not been taken care of.
Hearing Ding Ning's words, Chen Xin nodded clearly. Obviously he had anticipated this situation, so he said to Ding Ning: "Long Niang also mentioned it to me when I came here. Let me take a look. It's her house anyway. Although she has moved to my place now, her family still can't just give up like that."
"Well, Axin, tell me when you go. If I have time, I will go together. I still have everything there!" Ding Ning thought of the things that he hadn't had time to bring out, and said to Chen Xin.
Chen Xin nodded and took note, then glanced at the cafeteria, and asked Ding Ning and Qin Lan: "Can I get something to eat here? I'm a little hungry, Alan, are you hungry?"
"It's kind of, but there are too many people here. Let's eat what we bring." Qin Lan also glanced at the cafeteria, and shook her head directly when she saw the long line at the cafeteria's window. She and Chen Xin were motivated. There is emergency food in the armor, so there is no need to squeeze with these survivors here.
Chen Xin also nodded in agreement, and asked Ding Ning, "Xiao Ding, is Alan's room still reserved? Or do you know where we can go to eat?"
"Sister Lan's room is still left, so you can go straight ahead." 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, she was more hungry when she smelled the scent of food.
But where the job is, no matter how hungry she is, she must stick to her post before she can rest, instead of fetching food because she is hungry.
Chen Xin and Qin Lan didn't say much when they saw this. After saying goodbye to Ding Ning, they walked out of the cafeteria together.
Seeing Chen Xin and Qin Lan walking outside, the researchers on the side immediately posted them again and asked Chen Xin: "Mr. Chen Xin, what are you going to do?"
"I'm going to take a rest and eat something. When I came in the morning, I came out in a hurry. After I came here, I was busy again, and my stomach was a little hungry." Chen Xin replied, watching the researchers think for a while. Said: "You also go eat something, don't have to follow me all the time."
The researcher hurriedly shook his head and said: "No need~EbookFREE.me~ We have already had lunch before we came here. I'll follow Mr. Chen Xin. You can see Mr. Chen Xin transforming the equipment. The words also benefited a lot, very enlightening!"
Chen Xin knows that the fuzzy concept of the information state of the system can instill a large amount of knowledge and images in an instant to those who see the upgrading process, and the more knowledgeable people can obtain, the more instillation, and it is not surprising what the scientific researchers say, so Nodded, tacitly acquiescing that the other party followed him.
However, Chen Xin went to restart the power armor he had parked before. After wearing the power armor and Qin Lan came 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 was away for more than a month, and a thin layer of dust fell on the table.
Qin Lan found out the rag and wiped the tables and chairs, and then greeted Chen Xin to sit down, but the researchers who followed them did not come in, but obsessively looked at the power armor of Chen Xin and Qin Lan parked at the door. The deputy wants to study the look.
Chen Xin didn't care about him either, just took out the emergency food brought by Qin Lan from the silo behind the power armor and ate.
