Chapter 292

When Chen Xin and his researchers left the room where the ground source heat pump was installed and came to the canteen of the special police force, the heating effect of the ground source heat pump was obviously improved after the transformation. Although the temperature is still cold, the temperature in the room has increased significantly.

Before Chen Xin's renovation of the ground source heat pump, people here wanted to stick it on the radiator, but now they have changed from water heating to air heating. These people are just around the radiator, and obviously they can feel comfortable.

In fact, it's easy to understand that water heating is to heat water through a boiler or heat source. The temperature is generally about 60 ~ 80 ℃, which can be held directly by hand without feeling very hot.

But gas heating is to heat the water into high-temperature steam through the heat source. When the temperature is above 100 ℃, it can scald people.

Although both of them are heating, the gap in heating efficiency can be said to be very different.

For the heating system, if there is no enough surplus heat source, there is no way to use air heating.

However, for now, only the SWAT team can enjoy the air heating in the whole refuge of the city police station. After all, the whole refuge uses water heating, and the air heating and water heating can not operate at the same time. So just now, when Chen Xin was upgrading, he only transformed the heating system connected with the ground source heat pump in the area where the SWAT team is located into air heating system Warm.

If we want to transform the heating of the whole city police shelter into air heating, we can only wait for Chen Xin to transform the boiler of the shelter.

For this, Chen Xin is not worried at all, because it is really no trouble at all. The only thing he has to wait for is for the municipal police station to collect all the raw materials for the boiler transformation.

So at this time, Chen Xin's look is much more relaxed than before. When he finds Qin LAN and Ding Ning in the canteen, his face is also smiling.

"Xiao Ding, a LAN!" Chen Xinchong greets them and walks to them. The researcher beside him walks to one side with great insight, without disturbing Chen Xin and his friends.

"Ah Xin! Sister Lan said that you just went to do the transformation of the ground source heat pump. What's the situation now? " Ding Ning is very happy to see Chen Xin's performance. While warmly greeting him, he also inquires with concern.

"The upgrade has been completed. Don't you feel the temperature of the heating system rising now?" Chen Xinchong Ding Ning smiles for a while, explains one sentence and then asks her, "Xiao Ding, do you live here recently? Do you know what's going on in the dragon lady's house? "

For this problem, Ding Ning shook his head in embarrassment and explained: "when the blizzard came, I was on duty here and began to go back once, but later there was no time to go back. That place should have been buried by the blizzard now."

At this point, 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 the house is buried in snow. Although it's due to the weather and irresistible manpower, it's true that she didn't take care of it.

Hearing Ding Ning say so, Chen Xin nodded clearly, this situation he obviously expected, so he said to Ding Ning: "when I came here, long Niang also talked to me. I'll go back and have a look. It's her home. Although she has moved to my home now, her home still can't give up."

"Well, ah Xin, tell me when you go. If I have time, I'll go with you. I still have my things there." Ding Ning thought of what he didn't have time to bring out and said a word to Chen Xin.

Chen Xin nodded and took a look at the canteen. He asked Ding Ning and Qin LAN, "can I get something to eat here? I'm a little hungry. Are you hungry, Alain

"A little bit, but there are too many people here. We'd better eat our own food." Qin Lan also took a look at the canteen, and saw the long line at the dining window. She and Chen Xin had emergency food in their power armor, so there was no need to squeeze with these survivors here.

Chen Xin also nodded to agree, so he asked Ding Ning: "Xiao Ding, does a LAN's room still exist? Or do you know where we can get something to eat? "

"Sister Lan's room is still reserved. You can go there directly." Ding Ning looks at Chen Xin and Qin LAN enviously.

In fact, she is already very hungry, especially when she is on duty in the canteen. She is more likely to be hungry when she smells the food.

But the responsibility is that no matter how hungry she is, she must stick to her post before she can have a rest, instead of getting something to eat just because she is hungry.

Chen Xin and Qin LAN didn't say much. After saying goodbye to Ding Ning, they went out to the canteen together.

Seeing Chen Xin and Qin LAN walking out, the researchers on one side immediately pasted up and asked Chen Xin, "Mr. Chen Xin, what are you going to do?"

"I'm going to have a rest and eat. I came out in a hurry in the morning. After I came here, I was busy. I was a little hungry. " Chen Xin answered, looking at the scientific research personnel thought for a while, said: "you also go to eat something, don't always follow me."The researcher quickly shook his head and said, "no, no, we had lunch before we came here. I'd better follow Mr. Chen Xin. It's very enlightening for me to see Mr. Chen Xin transform your equipment."

Chen Xin knows that the concept of information state of the system is vague, which can instill a lot of knowledge and pictures into people who see the upgrading process in an instant. The more knowledge people have, the more instillation they can get. It's not surprising what the scientific researchers said, so he nodded and acquiesced to the other party's following their own things.

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

The room seems to be the same as before, but Qin Lan was away for more than a month, and a thin layer of ash fell on the table.

Qin LAN finds out the rag and wipes the table and chair. Then she asks Chen Xin to sit down. However, the researchers who are with them do not come in. Instead, they are obsessed with looking at the power armor that Chen Xin and Qin LAN stop at the door, looking like they want to study.

Chen Xin doesn't care about this either. He and Qin LAN just take out the emergency food from the silo behind the power armor and eat it.
